Module Summary — Part 1 of 2 — The Diagnosis
The Debt Cycle — the essence of it, in two minutes.
Most SME cash flow forecasts show revenue, costs, and working capital — but rarely map the total debt service obligation month by month. A business can be profitable on paper and still run out of cash, because debt repayments consume more cash than operations generate. This isn't rare — it's the documented reality behind thousands of Australian business closures from 2022 to 2026.
The metric that matters: DSCR
DSCR = Net Operating Income (EBIT) ÷ Total Annual Debt Service
Above 1.0 means the business can cover its debt. Below 1.0, it can't — and must fund the shortfall from reserves, borrowing, or asset sales. Lenders typically require 1.25–1.35. Many SMEs are now below 1.0 without knowing it.
Why 2026 is the sharpest point of stress
Pandemic-era loans were taken on at record-low rates with repayment holidays. Since 2022: 425 basis points of RBA rate rises, repayment holidays ending, and the ATO resuming enforcement have converged simultaneously — while the cash buffers that once absorbed shocks have returned to pre-pandemic (i.e. much thinner) levels. Around 70–75% of small business debt is on variable rates — higher than almost any other developed economy — so rate rises transmit faster and harder here than elsewhere.
The debt trap sequence — how it actually unfolds
The critical point: this is a capital structure failure, not a performance failure. A business can be serving customers well and still close because the debt structure built during expansion can't survive the contraction. See The Formula for the equivalent breakeven-gap mechanism.

The problem most businesses do not model
Ask the CFO of a medium-sized Australian business to present the cash flow forecast for the next 12 months. In the majority of cases, that forecast will show revenue projections, operating cost assumptions, and working capital movements. What it will rarely show — clearly, explicitly, and with the full compounding effect mapped month by month — is the total debt and credit cycle repayment obligation: the sum of all principal repayments, interest charges, lease obligations, ATO payment plan instalments, and equipment finance repayments falling due across the period, and the precise cash surplus or deficit remaining after those obligations are met.
This omission is not a minor gap in financial reporting. It is, in the experience of practitioners who have worked through business distress at the smaller and medium end of the market, one of the most consistent and consequential shortcomings in SME financial governance. A business can be operationally profitable — generating positive EBITDA month after month — and still be cash flow negative and heading for insolvency, because the debt service obligations it has accumulated are consuming more than the business can generate after paying its operating costs. This is not a theoretical scenario. It is the documented reality of thousands of Australian businesses in the period from 2022 to 2026.
"I recently came across a highly profitable business that was scrambling for short-term funding with an equipment buy-back obligation looming on the horizon. With few options under time pressure, the business owner opted to take an offer to sell a portion of the business at a low valuation in order to remedy its short-term cash flow crunch."

Understanding the debt service coverage ratio — the metric every owner must know
The Debt Service Coverage Ratio (DSCR) is the single most important financial metric for any business carrying significant debt obligations, and it is among the least commonly monitored by SME boards. It measures, in the clearest possible terms, whether the business generates enough cash to service its debt — not just its operating costs, but the full principal and interest obligations of every facility it carries.
Debt Service Coverage Ratio — the fundamental test
DSCR = Net Operating Income (EBIT) ÷ Total Annual Debt Service
Where Total Annual Debt Service = all interest payments + all principal repayments + lease obligations + ATO payment plan instalments + equipment finance repayments falling due in the period. A DSCR above 1.0 means the business generates enough to cover its obligations. A DSCR below 1.0 means it does not — and must fund the shortfall from cash reserves, additional borrowing, or asset sales. Most commercial lenders require a minimum DSCR of 1.25 to 1.35 at the time of lending. Many SMEs are now operating below 1.0 without knowing it.
The profit vs cash trap — why profitable businesses fail
Cash Available = EBITDA — Tax — Principal Repayments — Interest — Lease Payments — Capital Expenditure
EBITDA (Earnings Before Interest, Tax, Depreciation and Amortisation) is an accounting profit measure. It deliberately excludes interest and principal — the very obligations that determine whether the business can survive. A business reporting strong EBITDA but carrying heavy debt may have negative free cash flow after servicing that debt. The board that monitors EBITDA without monitoring DSCR is managing an incomplete financial picture.
How Australia's debt service burden became extraordinary — the 2022 to 2026 cycle
To understand why debt service has become such a critical stress point for Australian SMEs in 2025 and 2026, it is necessary to trace the credit cycle from 2020 forward. The pandemic period produced an unprecedented expansion of business debt, facilitated by government guarantee schemes, record low interest rates, and forbearance by the ATO and major lenders. The SME Recovery Loan Scheme, which closed for new loans on 30 June 2022, enabled businesses with turnover up to $250 million to access government-backed lending with repayment holidays of up to 24 months and generous terms. The Commonwealth guaranteed 50 per cent of loans under the earlier Coronavirus SME Guarantee Scheme. Together these schemes placed an estimated $40 billion of additional lending into the SME sector at the lowest interest rates in Australian history.
The repayment holiday period created a dangerous illusion of financial health. Businesses that had taken on debt during the pandemic were not yet feeling the full cost of that debt, because principal repayments had not yet commenced and interest charges were minimal. When the repayment holidays ended — largely through 2022 and 2023 — and when the RBA began raising the cash rate in May 2022 in response to inflation, these two forces converged simultaneously on businesses that had rebuilt their cost structures for a low-rate, low-repayment environment.
The convergence that nobody planned for — 2022 to 2024
Between May 2022 and November 2023, the RBA raised the cash rate by approximately 425 basis points — the fastest and largest tightening cycle in three decades. SME variable lending rates rose by approximately 365 basis points over the same period, confirmed by the RBA's 2024 Small Business Economic and Financial Conditions Bulletin. On a $562,500 variable facility — close to the average SME loan amount — 365 basis points adds approximately $20,530 per year in additional interest. That is the equivalent of a part-time employee's salary extracted from the business through higher debt servicing costs, every year, with no offsetting revenue increase.
At the same time, pandemic-era loan repayment holidays expired, ATO payment plans on deferred obligations began requiring instalments, and the cash buffers accumulated during COVID — higher for larger SMEs, much lower for smaller ones — were progressively depleted. The RBA's October 2022 Financial Stability Review confirmed that average cash balances for SMEs had been declining through 2022, with approximately one-fifth of all firms carrying cash buffers of less than one month's expenses. The businesses that entered 2023 with thin cash buffers, variable rate debt, ATO repayment obligations, and a cost structure built for the 2020 to 2021 environment were in structural trouble before any external shock occurred.
Australia's variable rate exposure — structurally more dangerous than any other economy
Australia's debt service problem is not simply a product of the rate hiking cycle — it is amplified by a structural feature of the Australian lending market that makes monetary policy transmit faster, harder, and more directly into business cash flows than in almost any other developed economy.
Approximately 70 to 75 per cent of small business debt in Australia is held on variable rates, according to RBA Statistical Table D14 data. This compares to a much more balanced mix for large businesses, which have greater access to fixed-rate bond markets and long-term debt structures. This structural skew is not a choice made from a position of strength — it reflects the reality that small businesses are pushed toward variable rate products because they cannot access fixed-rate capital markets, because banks price fixed-rate SME lending at a significant premium, and because products like overdrafts and revolving credit facilities — which are inherently variable — are the working capital tools most accessible to smaller operators.
The CBA's head of Australian economics, Gareth Aird, described the consequence precisely: Australia's debt service ratio rose "more swiftly in Australia than in any other region" during the 2022 to 2023 tightening cycle. The change in Australia's debt service ratio since the global co-ordinated tightening cycle began is "extraordinary relative to other jurisdictions" — dwarfing that of any other major region due to the structure of the Australian mortgage and business lending market and the directness with which monetary policy transmits to borrowers.
The owner-operator double exposure
For the owner-director of a smaller SME, the variable rate exposure extends beyond the business. The same person typically carries a variable rate residential mortgage. When rates rise, business cash flow tightens — reducing the income the owner can draw from the business — while simultaneously the personal mortgage becomes harder to service. This feedback loop, where business debt stress and personal mortgage stress compound each other, is a pattern that the insolvency and personal bankruptcy statistics of 2023 to 2025 directly reflect.
The non-bank lending escalation
As bank credit tightened and SME credit scores declined — down 0.51% on average in Q1 2025, per Equifax — businesses unable to access or refinance conventional bank facilities turned increasingly to non-bank lenders. The non-bank share of SME lending has increased strongly since the start of 2022. These facilities carry materially higher interest rates, often include stricter covenant terms, and in some cases carry accelerated repayment provisions that can be triggered by covenant breaches — converting a manageable debt into an immediate crisis.
The ATO as the largest legacy creditor
Grant Thornton partner John McInerney captured the structural reality in 2022: the ATO was a major creditor in 70 per cent of SME insolvencies before COVID and is "now likely over-represented in the creditor pool as a result of the growth in ATO business debt during the pandemic." In Q1 2025, 30,320 businesses had an active ATO default totalling $9.48 billion — an average of $410,000 per default. For these businesses, the ATO is not just a creditor — it is the primary debt service obligation, with interest now no longer tax deductible from 1 July 2025.
The private credit tightening of 2025
BDO's January 2025 credit analysis identified the first signs of private credit funds re-assessing their loan portfolios against a backdrop of rising defaults. Some funds have begun calling in loans to manage their capital positions as new inflows moderate. For SMEs that refinanced into private credit during the post-COVID period, this represents a potential acceleration of repayment obligations at exactly the moment when operating cash flow is under its greatest pressure.
The pandemic legacy debt problem — a deferred reckoning
One of the most important and least discussed dimensions of the current debt cycle stress is what Grant Thornton and other practitioners describe as "legacy debt" — the accumulated obligations from the pandemic period that businesses have been servicing since 2022 while simultaneously managing the cost inflation, rate rises, and revenue pressures documented throughout this series.
The RBA's September 2024 Financial Stability Review identified three main drivers of the post-pandemic rise in company insolvencies: the removal of pandemic support measures, more challenging trading conditions as the economy slowed, and the ATO resuming enforcement on unpaid taxes. These three factors are not independent — they represent three simultaneous demand pulls on the same limited pool of business cash flow. A business meeting its pandemic-era loan repayments, its ATO payment plan instalments, and its current operating obligations while trading in a weaker revenue environment is not managing one problem. It is managing three compounding obligations from a contracting cash base.
The RBA noted in the same review that the high cash buffers accumulated during the pandemic had "returned to more normal levels across small and medium enterprises," meaning the financial cushion that allowed many businesses to absorb the early phase of this triple stress has now been substantially depleted. The businesses entering 2025 and 2026 in distress are doing so without the buffer that allowed them to absorb 2022 and 2023.
"While a repayment plan may appear attractive to a debt-riddled business owner, there is often a failure to address the underlying business model, in which case the business may end up collapsing with a heavier debt burden. As businesses find their feet in the new normal, advisors will be called on more than ever to assist clients deal with legacy debts."
— John McInerney, Partner Financial Advisory, Grant Thornton · 2022
"New projects drive cash flow to pay employees, suppliers and the ATO, but unfortunately, a stagnant or growing pool of debt and creditors may be their reality — despite them continuing to deliver on projects. This challenge is not unique to the construction industry — we see it across a vast number of sectors; business owners trying to decide whether to deal with the financial difficulties now, or later down the track."

Why this does not appear in the cash flow forecast — the governance gap
The central question raised by this analysis — and by the personal experience of the practitioner who has lived through it — is not why debt service cycles create financial stress. That is mechanically obvious once the numbers are laid out. The central question is why the debt service cycle is so consistently absent from the cash flow forecasts, equity planning, and asset and debt management frameworks presented to SME boards.
The answer reflects several interlocking gaps in financial governance that are deeply embedded in the way smaller and medium Australian businesses manage their finances.
Why debt cycle repayments disappear from SME financial governance
Cash flow forecasts focus on operations, not obligations
The standard SME cash flow forecast is built around trading activity — revenue in, costs out, working capital movement. Debt repayments are either excluded entirely or treated as a single line item rather than being mapped month by month against their actual due dates, variable rate exposure, and covenant requirements. A forecast that shows positive monthly cash flows but excludes a $180,000 principal repayment falling due in month six is not a cash flow forecast — it is an operational projection that will produce a crisis.
CEOs and boards monitor profitability, not debt serviceability
Board reporting in growing SMEs typically centres on revenue, gross margin, EBITDA, and debtor days. These are important measures of operating performance. They do not measure debt serviceability. A business with strong EBITDA and a DSCR below 1.0 is operationally successful and financially fragile simultaneously. The board that does not monitor DSCR, interest coverage ratio, and the full debt maturity schedule has an incomplete picture of the business's financial health.
Debt is treated as a one-time decision, not an ongoing risk
When a business takes on a new facility — a term loan, equipment finance, or lease — the financial analysis typically focuses on the purpose and the initial serviceability. What is rarely modelled is the cumulative effect of multiple debt facilities taken on at different points, maturing or repricing at different times, in combination with changing interest rates and changing revenue conditions. The debt portfolio is managed facility by facility rather than as an integrated obligation structure.
Equity and asset planning are treated separately from debt planning
The equity base of a business — the capital available to absorb losses, fund growth, and provide a buffer against debt service obligations — is rarely planned explicitly in smaller SMEs. Equity is what remains after everything else is accounted for, rather than a target maintained as a structural discipline. When debt grows and equity is not maintained, the leverage ratio deteriorates silently. When the credit cycle turns and lenders reassess security values, businesses discover that equity they believed they had has evaporated.
The credit cycle — how tightening credit amplifies debt cycle stress
The debt service cycle and the credit cycle interact in a way that makes each more damaging than either would be alone. The credit cycle describes the alternating periods of expanding and contracting credit availability that characterise every market economy. During the expansion phase — as Australia experienced from 2020 to 2022 — credit is abundant, terms are generous, and marginal borrowers can access capital they could not in more normal conditions. During the contraction phase — as Australia has experienced from 2022 onwards — credit availability tightens, terms harden, and the businesses that borrowed during the expansion find that the refinancing options they assumed would be available are no longer accessible on the terms they need.
BDO's 2025 credit analysis describes the current phase precisely: "If 2024 was the year of the private credit boom, 2025 is shaping up as the year for lenders to take stock and be more nuanced with their view of risk." As credit contracts, businesses that need to refinance legacy pandemic-era debt or roll over short-term working capital facilities discover that the terms available in 2025 are materially worse than the terms they locked in during 2020 and 2021. Higher rates, tighter covenants, lower advance rates against security, and more conservative property valuations all combine to make refinancing more expensive and less accessible.
The Equifax Q1 2025 Commercial Credit Report documented this dynamic with precision: SME credit demand fell sharply by 8.25 per cent compared to Q1 2024 — the lowest in several years. Importantly, this was not primarily a demand-side withdrawal. It reflected a combination of SMEs becoming more cautious about taking on additional debt in a high-rate environment and lenders tightening standards against declining SME credit scores. The construction sector showed the most acute symptoms: credit demand from construction SMEs fell 18.1 per cent, while simultaneously insolvencies remained elevated and construction borrowers were taking approximately 2.4 times longer to pay their suppliers than businesses in other sectors.
The debt trap sequence — how it actually unfolds
Debt taken on during expansion — at low rates and generous terms
During 2020 to 2022, businesses take on pandemic-era loans, government-guaranteed facilities, and equipment finance at historically low variable rates. Repayment holidays mask the true cash flow impact. The business plans around a low-rate, low-repayment environment. Growth commitments — new branches, additional staff, expanded inventory — are made against this assumption.
Rates rise — the variable rate exposure activates
From May 2022, 13 consecutive RBA rate increases raise the cash rate by 425 basis points. Variable rate SME lending costs rise by 365 basis points. Every dollar of variable rate debt now costs materially more to service. For a business carrying $1 million in variable rate facilities, annual interest costs increase by approximately $36,500 — before any principal repayment obligations are considered.
Repayment holidays end — principal falls due simultaneously
Pandemic-era loan repayment holidays expire through 2022 and 2023. Principal repayments commence at the same time as interest costs have risen substantially. The ATO, having deferred collection through the pandemic, begins issuing payment plans and enforcement actions on accumulated obligations. Three distinct debt service streams activate simultaneously: commercial loan principal, higher variable interest, and ATO repayment plan instalments.
Cash buffers are consumed servicing the obligation stack
The pandemic cash buffers — built from government support, reduced spending, and precautionary saving — are drawn down to bridge the gap between operating cash flows and the combined debt service obligation. RBA data confirms these buffers have returned to pre-pandemic levels for SMEs. For many businesses, they have been depleted entirely. The business is now servicing its debt stack from operating cash flow alone, with no buffer to absorb revenue variability or unexpected costs.
Credit tightens — refinancing is unavailable or unaffordable
The business attempts to refinance or extend its facilities to reduce the immediate repayment pressure. It discovers that its credit score has declined, its security values have moderated, and the terms available in 2024 and 2025 are materially worse than those it obtained in 2020 and 2021. Non-bank lenders, who had expanded aggressively, are now reviewing their portfolios and in some cases calling in loans. The refinancing option — which the business assumed was available — is not available at a price the cash flow can support.
DSCR falls below 1.0 — insolvency approaches without operational decline
The business reaches the point where its total debt service obligations exceed its net operating income. The DSCR falls below 1.0. The business is not operationally failing — it may still be generating positive EBITDA and serving its customers well. But the accumulated debt service obligation structure has grown beyond what the business can sustain from its cash flows. Without a recapitalisation, a debt restructure, or an asset sale, insolvency is the destination — not because the business lost customers, but because the debt cycle consumed the cash that operations generated.
A different trigger, the same trap — startups and early-growth funding
The six-stage sequence above is driven by interest rates and bank debt. Startups and early-growth businesses face a related but distinct version of the same trap — one triggered not by the RBA, but by the funder's own confidence.
Friends, family, and early investors typically supply funding as equity, not as a loan. That distinction matters more than founders usually realise. A bank lends against a security and enforces its rights through a defined legal process if repayments are missed. An equity funder's leverage is different and, in practice, can be more immediate: as a shareholder — often a director as well — they can withdraw support, decline to fund a promised next tranche, or move to wind up the business if they judge their own position to be at risk. That judgment does not have to be about the business's actual operating health. It can be driven by the funder's own circumstances, their reading of the founder, or simply a loss of confidence — and the business has no enforceable right to insist otherwise.
This creates a specific, avoidable failure mode: a founder treats a funder's in-principle commitment — the verbal assurance, the term sheet still in due diligence, the "next round" everyone expects to close — as if it were cash already in the bank. Spending proceeds against that expectation, before it is actually secured and drawn, is the startup equivalent of Stage 1 above: a growth commitment made against an assumption that later proves unreliable. When the funding does not land on schedule, or at all, the business discovers — often suddenly — that it has been trading without the cash it was counting on, for longer than anyone realised.
The governance complication is that the people best placed to see this coming are frequently the same people whose confidence is the trigger. When directors are drawn from the equity holders and funders themselves, there is a direct tension between their duty to keep the company trading solvently and their personal interest in protecting their own position. That conflict is structural, not a matter of individual bad faith — and it is precisely why the Formula's standard does not bend for a business's stage or funding story. A business is solvent when its cash IN — including funding that is genuinely committed and drawable, not merely hoped for — equals or exceeds its cash OUT. Committed-but-undrawn funding, contingent on a funder's continuing confidence, is not cash in hand. Treating it as such is the same "hope-based" cashflow the rest of this page describes, wearing a different costume.
Real-world cases — the debt cycle in practice
The six-stage sequence described above is not theoretical. It is the documented pattern behind some of Australia's most significant business closures of the past three years — from household-name corporates to the thousands of smaller construction, hospitality, and retail businesses that collapsed without making national headlines. Three cases illustrate the mechanism at different scales.
A note on the cases below: each is drawn entirely from public reporting and the cited sources, and is included solely to illustrate the debt cycle mechanism this page describes — for solvency education purposes, not commentary on any individual, director, or entity beyond what is already public record. These are demonstrations of a pattern, not an assessment of any party's conduct.
Healthscope — the $5.7 billion debt cycle catastrophe — 2019 to 2025
Healthscope, Australia's second-largest private hospital operator with 39 facilities and over 650,000 patients treated annually, entered receivership in May 2025 owing approximately $1.6 billion. It is the clearest large-scale illustration in Australian corporate history of a business destroyed not by operational decline but by a debt structure that could not survive a turning credit cycle.
In 2019, Canadian private equity giant Brookfield acquired Healthscope for $5.7 billion — paying 21 times EBITDA, a premium that required approximately $1.9 billion in debt at entry, representing a leverage ratio of approximately 7 times EBITDA. The debt load was manageable under the assumptions of the acquisition model: an ageing population driving steady demand, stable insurer contracts, and low interest rates. Every one of those assumptions was invalidated within 12 months of closing.
COVID throttled elective surgeries — Healthscope's primary revenue stream. Labour shortages drove wage costs higher. As the pandemic receded, inflation compounded operational costs while rising interest rates made the debt load progressively more expensive to service. By 2024, only 6 of Healthscope's 37 hospitals were profitable. Brookfield injected over $200 million in additional equity — too little, too late. In May 2025, lenders appointed McGrathNicol as receivers, wiping out Brookfield's entire equity investment of approximately $1.2 billion — the largest private equity write-down in Australia since CVC's loss on Channel 9 in 2012.
Lesson: A profitable, operationally capable business — one treating hundreds of thousands of patients — was destroyed by a capital structure that could not withstand the simultaneous pressure of COVID revenue loss, rising wage costs, and a rate hiking cycle. The DSCR at entry was optimistic. The DSCR in 2023 was terminal. Sources: Ashurst Distress in the Market 2025; SmartCompany; RSM Australia; ABSI Analysis.
Porter Davis Homes — the SME construction debt cycle — 2023
Porter Davis Homes collapsed in March 2023 — one of 2,832 construction companies that entered insolvency in the 2023–24 financial year alone. It left approximately 4,500 home buyers stranded with unfinished houses or unrecoverable deposits, and owed money to around 2,000 creditors including subcontractors — bricklayers, plumbers, plasterers, and painters — who had not been paid since before Christmas 2022.
The Porter Davis case illustrates the specific debt cycle trap of the construction industry: the fixed-price contract model. Builders lock in a price at contract signing, then must absorb all cost increases — materials, labour, fuel — between signing and completion. When input costs rose sharply through 2021 and 2022, fixed-price contracts became loss-making. The business kept winning new contracts to generate the cash flow needed to service existing debt and pay creditors on prior projects — a pattern RSM's Brisbane-based restructuring partner Mitch Herrett described as building companies "carrying significant debts from prior projects while new projects drive cash flow to pay employees, suppliers and the ATO."
When the new contract pipeline could no longer generate enough cash to bridge the accumulated deficit, the entire structure collapsed simultaneously. The Commonwealth Bank was the largest secured creditor — recovered first. The 2,000 unsecured creditors, including small subcontracting businesses, were left with losses many could not absorb.
Lesson: The construction debt trap is a debt cycle problem disguised as a trading problem. New revenue is consumed servicing old debt rather than building equity. The business appears to be trading when it is actually drowning — and the subcontractors downstream have no visibility of the water rising until it is too late.

Dyldam — aggressive expansion, borrowed capital, inevitable collapse — 2023
Dyldam's collapse in February 2023 provides the clearest example of the growth trap meeting the debt cycle at a medium business scale. The company had aggressively expanded its residential development operations using borrowed funds, becoming heavily leveraged and structurally vulnerable to market downturns and project delays. When both arrived simultaneously — in the form of rising interest rates, construction cost inflation, and a softening property market — the debt structure could not be maintained.
Dyldam represents the pattern described in Article 4 of this series — the six-stage growth trap — playing out with debt cycle amplification. The decision to fund expansion with debt rather than equity meant every percentage point of rate increase directly compressed the available cash for operations. When the credit cycle turned, the refinancing Dyldam had assumed would be available was not. The business entered liquidation with multiple projects unfinished and investors and homebuyers facing significant losses.
Lesson: Debt-funded expansion is a bet on the credit cycle remaining favourable. When the cycle turns, the leverage that made the growth possible becomes the mechanism of the collapse. Sources: Mastt Construction Industry Analysis; ASIC Insolvency Statistics 2022–23.
The ATO debt epidemic — 30,320 businesses in active default — Q1 2025
Beyond the named corporate collapses, the most revealing case study of the debt cycle in action at the SME level is the ATO's own enforcement data. In Q1 2025, 30,320 businesses had an active ATO default totalling $9.48 billion — an average of $410,000 per default. These are not businesses that chose not to pay their tax. They are businesses for which the ATO became, in the ATO's own Second Commissioner's words, "the bank of last resort" — the creditor used to fund ongoing operations when all conventional credit had been exhausted.
The ATO's total debt book has surged to over $105 billion — the highest on record — with $46.4 billion considered collectible, nearly double what it was in 2019. One in three businesses with significant ATO debt did not survive the year. From 1 July 2025, the general interest charge on unpaid ATO debt is no longer tax deductible, meaning a business carrying $100,000 in ATO debt is now paying the full $11,000 per year in non-deductible interest — compounding a problem that was already unsustainable for most of the 30,320 businesses in default.
RSM's construction industry analysis makes the practitioner observation that cuts to the core of the problem: "New projects drive cash flow to pay employees, suppliers and the ATO, but unfortunately, a stagnant or growing pool of debt and creditors may be their reality — despite them continuing to deliver on projects." This is the debt cycle trap at the SME level: the business is working, but the debt is growing faster than the work can service it.
Lesson: When 30,320 businesses have an average ATO default of $410,000 each, the scale of the debt cycle crisis at the SME level dwarfs anything captured in the corporate insolvency headlines. These are the businesses behind the statistics — and most of them have no board, no CFO, no debt maturity schedule, and no DSCR model.

The current environment — why 2026 is the most acute point of debt cycle stress
Every dimension of the debt cycle stress documented in this article has intensified in the period from late 2025 through April 2026. The oil supply crisis triggered by conflict affecting the Strait of Hormuz from late February 2026 has added a new cost pressure layer on top of an already stressed debt service environment. Deloitte's April 2026 analysis forecasts CPI peaking at 4.9 per cent in June 2026 — above the RBA's 2 to 3 per cent target band — with a further interest rate increase anticipated in the June quarter. The February 2026 rate increase already clawed back 25 basis points of the relief businesses received from the 2025 rate cuts.
CreditorWatch's May 2025 economic analysis noted that "low unemployment helps underpin consumer spending and debt repayment, which prevents a more significant credit cycle" — but also confirmed that pressures on consumers and businesses were expected to remain elevated through the second half of 2025. Equifax's Q1 2025 data showed 3,393 business insolvencies — up 28 per cent year-on-year and 214 per cent higher than Q1 2022. These are not businesses that failed operationally. A significant proportion are businesses that failed because the accumulated debt service obligations of the 2020 to 2022 expansion period, repriced at the interest rates of 2023 to 2026, exceeded the cash flow the business could generate.
For the independent director, the CFO, and the CEO of any medium business carrying significant debt in 2026 — and just as much for the owner of a smaller one — the debt cycle analysis in this article is not an academic exercise. It is a description of the financial environment in which the business is currently operating. The business that has a complete debt maturity schedule, monitors DSCR quarterly, stress tests its debt structure, and is actively managing its refinancing pipeline is navigating that environment with open eyes. The one that is not doing these things is navigating it blind — and relying on outcomes it cannot control to avoid consequences it has not modelled.
