ATO Debt & Business Lending: What Melbourne Business Owners Must Know in 2026

Every July, Melbourne accountants finish lodging tax returns and business owners open ATO portals to face a number they’ve been half-expecting. Post-EOFY ATO debt is almost a rite of passage for growing SMEs — but the question that lands in our office most often isn’t “how do I pay this?” It’s “will this stop me from getting a business loan?”

The answer is more nuanced — and more solvable — than most Melbourne business owners expect. Having spent over 20 years in business banking (including a decade at NAB before founding IFG), I’ve seen ATO debt derail finance applications that should have been straightforward, and I’ve seen it structured around when the approach was right. This guide covers both.

Can I get a business loan if I have ATO debt?

Yes — in many cases. But the answer depends entirely on which lender you approach and how your ATO situation is structured.

Banks (the major four and second-tier banks) have rigid credit policies around ATO debt. Their systems flag any ATO default, and in most cases an ATO debt on file will trigger an automatic decline — even if the amount is modest relative to your turnover and you have a solid trading history. This is not a credit officer making a judgment call; it is a policy filter that removes the application before a human sees it.

Non-bank and specialist lenders take a different approach. They are underwriting the deal by hand, which means they assess:

• The total amount of ATO debt relative to annual revenue
• Whether you have a current ATO payment arrangement in place (and are compliant with it)
• How long the debt has been outstanding and whether it is growing or reducing
• Your business cash flow and underlying profitability
• What security is available (property, equipment, debtors)

An active, compliant ATO payment plan changes the risk picture significantly for these lenders. It demonstrates that you are engaging with the ATO, that the debt is being managed, and that your business can service both the ATO commitment and new debt simultaneously. This is the critical distinction most business owners miss when they assume ATO debt is an automatic blocker.

Will ATO debt affect my credit score?

The ATO has the power to report your debt to credit reporting bureaus, but it only does so when all three of the following conditions are met:

1. The debt exceeds $100,000
2. The debt is more than 90 days overdue
3. The business is not engaging with the ATO to resolve the debt

Engagement is the key word. Under the ATO’s disclosure scheme, if you have an active payment arrangement — even if you’ve fallen slightly behind on it — the ATO does not report to credit bureaus. The scheme is designed to encourage businesses to come forward rather than avoid the problem. Once the ATO refers a debt, it appears on your commercial credit file and will be visible to any lender running a credit check.

Why the ATO’s 11.43% GIC now costs more than ever

Many business owners treat ATO debt as “free money” — a soft debt that can sit there while they prioritise other obligations. That calculation changed materially on 1 July 2025.

Prior to that date, the General Interest Charge (GIC) and Shortfall Interest Charge (SIC) were tax-deductible business expenses. If your marginal tax rate was 30%, a 10% GIC effectively cost you 7% after tax. Not ideal, but manageable compared to commercial finance rates.

From 1 July 2025, the government removed the deductibility of GIC and SIC entirely. The current GIC rate for Q1 FY2027 is 11.43% per annum — and every dollar of that is a real, after-tax cost to your business. There is no offset.

Compare this to a non-bank business term loan or commercial facility at 8–10%, which — as a genuine business expense — remains deductible. The maths now often favours paying out the ATO with business finance rather than letting the GIC run. This is a conversation for your accountant to quantify for your specific situation, but the directional shift is significant.

The bank vs non-bank divide — a former NAB banker explains

I spent years on the business banking side at NAB before moving into brokering. I understand exactly why banks decline ATO debt applications — and it is not always about credit risk.

Banks operate with highly centralised credit policies that are calibrated for volume. When they set a policy that says “any ATO default = decline,” they are not saying every business with ATO debt is a bad risk. They are saying it is more efficient to decline a cohort than to underwrite each case individually. The profitable, well-managed business with a short-term GST timing issue gets caught in the same net as the genuinely distressed operator.

Non-bank lenders do not have this constraint. Their business model is built around manual underwriting of deals that don’t fit bank templates. That makes them slower and more expensive — but for the right client, they are the right tool.

Factor	Major Bank	Non-Bank / Specialist Lender
ATO debt on file	Typically auto-decline	Assessed case-by-case
ATO payment plan in place	Still likely to decline	Significant positive factor
Underwriting approach	Automated / policy-driven	Manual / relationship-based
Rate	Lower (if approved)	Higher (reflects complexity)
Speed	Slower (more process)	Faster in many cases
Typical use case	Clean credit, established business	ATO debt, adverse history, complex structure

At IFG we work with a deliberately broad panel of bank, non-bank and specialist lenders. This matters when ATO debt is in the picture — we know which lenders are genuinely open to these applications and how to present the file so the underwriter understands the full story, not just the ATO flag.

What Melbourne SMEs should do right now

If you have ATO debt and are thinking about business finance in the next 6–12 months, here is the sequence that gives you the best outcome:

1. Engage with the ATO immediately if you haven’t already. Call or ask your accountant to call. Formalise a payment arrangement before the 90-day mark to protect your credit file. The ATO is often more flexible than business owners expect — they would rather receive payments than refer debts.
2. Keep the arrangement current. Missing a payment on an ATO plan can be as damaging as having no plan at all. Set up direct debits and make sure the cash flow supports it before you commit to the schedule.
3. Get your financials in order. Non-bank lenders will want 2 years of business tax returns or BAS statements, 3–6 months of business bank statements, and a clear picture of current ATO obligations. Have these ready before you approach a broker.
4. Talk to a business finance broker — not your bank. Your bank already knows about the ATO debt and has policy constraints. A broker with access to a broad lender panel can place the deal correctly from the start, rather than burning your credit file with declines.
5. Consider a consolidation strategy. In some cases, a short-term business loan or commercial facility to pay out the ATO entirely is the cleanest path — it removes the ATO obligation, stops the GIC accrual, and clears the way for standard bank finance down the track. Ask your accountant about the tax treatment and speak to us about the finance structure.

How IFG helps Melbourne SMEs with ATO debt access finance

We are not a residential brokerage that dabbles in business finance. Business lending has been a core part of IFG since we opened in 2003. Our directors have 45+ years of combined experience — including direct business banking experience at NAB — and we understand how to read a business finance application the way a credit officer reads it.

When ATO debt is in the picture, we do three things that most brokers don’t:

• We qualify the deal before we place it — understanding whether the lender panel we have access to can actually approve this file, rather than sending it everywhere and hoping.
• We package the application properly — a clear narrative about the ATO situation, the payment plan, and why the business is a sound credit risk despite the debt, changes outcomes at non-bank lenders.
• We look at the medium-term picture — sometimes the right move is a short-term non-bank facility to pay out the ATO, followed by a refinance to bank rates once the credit file is clean. We build that roadmap upfront.

Our enquiries are answered the same business day — by a director. If you have ATO debt and need to move on finance, call us first.

Frequently Asked Questions

Can I get a business loan if I have ATO debt?

Yes — in many cases. Banks will typically decline, but non-bank and specialist lenders assess the full picture: the amount, whether you have an active ATO payment arrangement, cash flow, and security. An active, compliant payment plan is a significant positive factor with these lenders.

Will ATO debt affect my credit score?

Only if all three conditions are met: the debt exceeds $100,000, it is 90+ days overdue, and the business is not engaging with the ATO. If you have an active payment arrangement, the ATO does not report to credit bureaus. Engagement is the critical protection — contact the ATO before the 90-day mark.

Should I use a business loan to pay out my ATO debt?

Often yes — especially since 1 July 2025 when GIC and SIC became non-deductible. With the ATO’s GIC at 11.43% and no tax offset, a business term loan at 8–10% (which remains deductible) can be cheaper in real terms and removes the ATO from future finance applications entirely. Speak with your accountant to quantify the saving for your situation.

How quickly can the ATO refer my debt to a credit bureau?

The ATO can refer once debt is $100,000+, 90+ days overdue, and the business is not engaging. There is no fixed timeline — the ATO exercises discretion. This is why proactively contacting the ATO and formalising a payment arrangement before the 90-day mark is so important. Once a debt is referred, it appears on your commercial credit file and lenders will see it.
