How Does ATO Tax Debt Affect Your Home Loan?

Managing a tax bill while trying to enter the property market or refinance your current home can feel like an uphill battle. In 2026, the Australian Taxation Office (ATO) took a firmer stance on debt collection, increasing the General Interest Charge (GIC) to 10.96% p.a. and reporting large, unmanaged debts to credit bureaus.

While major banks view tax debt as a high-risk factor, you can still secure approval by consolidating the debt into a mortgage or using specialist lenders who accept ATO payment arrangements.

For homeowners, this means that tax debt is no longer just a business expense. it is a critical factor that banks scrutinise when deciding whether to approve your mortgage.

Can I get a home loan if I have an ATO tax debt?

Yes, you can secure a home loan with ATO tax debt, provided you have a formal repayment plan in place or sufficient equity to consolidate the debt into your mortgage.

While Big 4 banks are often restrictive, specialist lenders allow you to borrow up to 90% of your property value (LVR) to pay off tax bills. The key is demonstrating good credit conduct by showing a history of on-time installments to the ATO or providing a reasonable explanation for a one-off tax event.

How much does tax debt reduce my borrowing power?

Tax debt reduces your borrowing power by the exact amount of your monthly repayment obligation, as lenders must subtract these costs from your disposable income during the servicing assessment.

For example, if you are paying the ATO $2,000 per month on a short-term plan, a lender will view that as a $2,000 reduction in your ability to pay a mortgage. In some cases, this can slash your total loan eligibility by hundreds of thousands of dollars unless the debt is consolidated into the long-term loan.

How much can I borrow if I have outstanding tax debt?

• Borrow up to 90% of the property value with a specialist lender. 95% on a case-by-case basis (stricter lending criteria apply).
• Borrow up to 85% of the property value, which includes the combined value of your tax debt and your current mortgage.
• Borrow up to 80% of the property value with a low doc loan (stricter lending criteria apply).

Can You Get a Home Loan with ATO Debt?

Yes. Depending on your situation, there are three main pathways to approval:

1. Refinancing & Consolidation

If you have enough equity in an existing property, you can roll your tax debt into your mortgage.

The Benefit: You replace a 10.96% interest rate with a mortgage rate (e.g., 6-7%) and spread the repayments over 30 years, drastically improving your monthly cash flow.

The Limit: Most specialist lenders allow you to borrow up to 90% of your property value (LVR) to consolidate tax debt.

2. Using Specialist Lenders

While the major banks often reject applicants with active tax debts, specialist lenders are more flexible.

These specialist lenders typically want to see at least 6 months of on-time payments if you are on an ATO payment plan.

For self-employed borrowers who aren’t up to date with their tax returns, low-doc loans allow you to prove income via BAS or an accountant’s letter.

3. The “Step” Strategy

If your credit is bruised by tax debt, our mortgage experts recommend:

• Consolidating the debt with a specialist lender at a slightly higher rate.
• Staying with that lender for 12–24 months while you “clean up” your ATO portal.
• Refinancing back to a major bank once the debt is gone and your credit score recovers.

What are the benefits of refinancing your tax debt?

Paying your ATO tax debt off by refinancing allows you to:

• Avoid high-interest-rate debts such as business loans.
• Manage your finances and cash flow better by consolidating your tax debt and other debts (if any) by rolling them into a single mortgage repayment.
• Keep your credit file clear, as overdue ATO tax debt now appears on it. Having an adverse listing on your credit file can also make it difficult to qualify for good interest rates in the future.
• Save on interest paid on the ATO tax debt. For the April–June 2026 quarter, the Australian Taxation Office (ATO) General Interest Charge (GIC) annual rate is 10.96% p.a. Generally, home loan interest rates, even with specialist lenders, are lower than the GIC rate.

However, taking out a tax debt loan has some disadvantages:

• There are fees and charges associated with taking out a tax debt loan.
• You are taking out another loan to cover the outstanding debt.
