ATO tax debt and your home loan: borrowing, refinancing and the risks
In plain English
An ATO tax debt doesn't automatically stop you getting a home loan — but it changes which lenders will deal with you. Major banks mostly decline applications with unmanaged tax arrears, while specialist and non-bank lenders will often lend if the debt is paid out at settlement or you can show a payment plan you've been keeping. Refinancing to clear a tax debt can make mathematical sense now that ATO interest runs at 11.43% and is no longer tax-deductible — but it converts an unsecured debt into one secured against your house, and that trade-off deserves a clear head.
The short answer
Three things decide how a tax debt affects a home loan application:
- Is the debt managed? A tax debt inside a payment plan you've been keeping looks very different to unmanaged arrears the lender finds in your ATO account statement.
- Has it been reported to credit bureaus? Most tax debts never appear on a credit file — but once one does, mainstream finance largely closes. See tax debt credit reporting.
- Which lender? Major banks and tax arrears rarely mix. Specialist and non-bank lenders price for it instead of declining.
So the realistic paths are: clear or restructure the debt first and apply clean; apply to a specialist lender with the debt disclosed and managed; or refinance and pay the ATO out at settlement.
How lenders actually treat ATO debt
| Major banks | Specialist / non-bank lenders | |
|---|---|---|
| Unmanaged tax arrears | Usually a decline, or a requirement that the debt be cleared before approval | Often acceptable if the loan pays the ATO out at settlement |
| Debt in a payment plan | Case by case; some want the plan cleared, most want long, clean conduct | Commonly acceptable with around 6 months of on-time plan payments |
| Tax debt on your credit file | Effectively a decline while listed | Some will still lend, at higher rates and lower LVR |
| Pricing | Standard rates | Higher rates and fees; refinancing back to a mainstream lender later is the usual plan |
Lenders don't have a live feed of your ATO account. They find tax debt through what you disclose, your ATO portal or integrated account statements (routinely requested from self-employed applicants), unusual BAS or financials, and — in the worst case — a credit bureau listing. Not disclosing a debt the documents will reveal anyway is the fastest way to turn a workable application into a dead one.
Where credit reporting changes the picture
The ATO can disclose business tax debts to credit reporting bureaus, but only where the debt is at least $100,000, more than 90 days overdue, and you are not engaging with the ATO about it — and only after a 28-day intent-to-disclose notice. A payment plan counts as engaging, which is why simply getting a payment plan in place is often the single most finance-protective step available: it keeps the debt off your credit file while you work out the longer-term answer.
Once a default is listed, it stays for years and most mainstream credit — home loans, business finance, even equipment leases — becomes difficult. If you've received an intent-to-disclose notice, the 28 days matter more for your future borrowing than almost anything else in this article.

Refinancing to pay out the ATO: why the maths often works now
Two changes have shifted this calculation in recent years:
- The general interest charge is 11.43% a year (Jul–Sep 2026 quarter), compounding daily. A home loan is typically several percentage points below that.
- GIC is no longer tax-deductible. Interest incurred from 1 July 2025 can't be claimed, so the 11.43% is a true after-tax cost. For a profitable business, that makes ATO debt one of the most expensive kinds of debt you can carry. More: ATO interest is no longer deductible.
Whether interest on the replacement loan is deductible depends on your circumstances — borrowing to pay a tax debt that arose from carrying on a business can be treated differently from private borrowing, and this is exactly the kind of question to put to your accountant before settlement, not after.
Two more parts of the calculation people miss. First, before refinancing an interest-heavy debt, it's worth asking the ATO to reduce the interest itself — GIC remission is real and costs nothing to request. Second, a 30-year loan term makes any debt look cheap per month; the honest comparison is total cost against a 1–2 year payment plan, not minimum repayments. Some borrowers split the difference: refinance on a 30-year term for serviceability, then direct the freed-up cash flow at the loan so the tax-debt portion is actually gone in a few years.
Mechanics worth knowing if you do proceed: the lender will usually want a current ATO payout figure and will pay the ATO directly at settlement rather than handing you the money — expect that, it's standard. Interest accrues daily until settlement, so the payout figure has a use-by date. And if enforcement is already under way — a garnishee on the account the loan would fund, or a winding-up application on foot — tell the broker upfront, because it changes which lenders are realistic and how fast things need to move.
What a broker will ask you for
- ATO integrated account or online services statements showing the current balance and its history
- Details of any payment plan and evidence of on-time payments
- Up-to-date lodgments — unlodged returns or BAS stall everything, and can also trigger an ATO default assessment that inflates the debt
- A short, honest explanation of how the debt arose and why it won't recur — lenders read a one-off event (illness, a bad debtor, a bad year) very differently from a pattern
- The usual: payslips or financials, bank statements, existing loan statements
A broker who regularly places tax-debt loans is worth finding — this is a niche, and a broker who only writes clean-credit deals may simply tell you it can't be done when the real answer is "not at a major bank". Good questions to ask any broker: which lenders on your panel accept ATO debt at settlement payout, what rate premium should I expect, and what's the exit plan back to a mainstream rate once the debt is cleared and my file is clean for six to twelve months?
Business loans vs putting it on the house
If the tax debt belongs to a trading business, a business or commercial loan may fund the payout without touching your home — commercial lenders are generally more used to tax debt than residential credit teams. The pricing is higher, but the security position matters more than the rate: a business loan that fails is a business problem; a home loan that fails is a house problem.
At the far end sit short-term caveat and second-mortgage lenders offering fast money against your property at rates that can exceed 1–2% a month. They have a place in genuine emergencies — a garnishee notice or winding-up deadline — but as a way to hold off the ATO indefinitely they usually just relocate the problem to somewhere more dangerous.
The real risk: making tax debt secured
AN UNSECURED DEBT BECOMES YOUR HOUSE
ATO debt is unsecured. The ATO rarely moves directly against a family home, and there are many steps before that point — see can the ATO take my house? A mortgage is different: miss the repayments and the lender's path to your home is short and well-practised. Refinancing tax debt onto the house is often sensible — but only when the business problem that created the debt is actually fixed. Borrowing against the home to clear one tax bill, then falling behind on the next BAS, is the most common way people end up worse off.
If a loan isn't the answer
Refinancing suits a fundamentally sound position with a one-off debt. If the debt keeps growing each quarter, the better conversation is usually about the underlying business: a payment plan sized to real cash flow, or for a company with under $1m in liabilities, small business restructuring — which can formally compromise the debt rather than just moving it.

Frequently asked questions
Will my tax debt show up when a lender does a credit check?
Usually not. The ATO only reports business tax debts of $100,000 or more that are over 90 days overdue where you aren't engaging with them, and only after a 28-day warning notice. Most tax debts never reach a credit file — but lenders can still find the debt through your ATO statements and disclosures.
Can I get a home loan while I'm on an ATO payment plan?
Often, yes — mainly through specialist and non-bank lenders, who typically want to see around six months of on-time plan payments. Major banks are stricter and may want the debt cleared first. The plan repayment is counted as a liability in your servicing calculation.
Is it better to refinance the tax debt or stay on a payment plan?
It depends on the numbers and the risk. A refinance usually wins on interest rate — GIC is 11.43% and no longer deductible — but it secures the debt against your home and can stretch it over decades. A payment plan keeps the debt unsecured and short. Many people compare both with a broker and an accountant before deciding.
Should I hide the tax debt from my lender?
No. Loan applications require honest disclosure of liabilities, and the debt is usually visible in the ATO statements lenders request from self-employed applicants anyway. Non-disclosure risks the loan being declined late, or worse, and doesn't survive contact with the paperwork.
Does refinancing to pay the ATO stop other ATO action?
Only actual payment stops it. Until settlement clears the debt, interest keeps accruing and enforcement action remains possible. If you've received a formal notice — a DPN, garnishee or statutory demand — the deadline on that notice runs regardless of a loan application in progress.
Can a company's tax debt affect my personal home loan?
It can — through a director penalty notice that makes company PAYG, GST or super debt personally yours, or through a director guarantee. Lenders assessing a director will often look at the company's position too. See company director liability.
