ATO Debt Consolidation Into Your Mortgage

Can I consolidate ATO debt into my home loan?

ATO debt stresses people out more than almost anything else we see. The good news is there is usually a clean path through it. This is exactly why you need a specialist broker who knows which lenders work for your situation.

Here is how it works at a high level: your new (or refinanced) home loan is sized to cover your existing mortgage balance plus the ATO debt. At settlement, the lender pays the ATO directly on your behalf. The tax debt is cleared in full, and you are left with a single home loan repayment at a significantly lower interest rate.

The ATO issues what is called a payout letter (sometimes called a "running balance account" statement) that confirms the exact amount owed, including any general interest charge that has accrued. Your broker organises this as part of the process - you do not need to chase it yourself.

We see this most often with self-employed clients who have fallen behind on BAS or income tax obligations. But it is not limited to the self-employed - PAYG workers can end up with ATO debt from investment property shortfalls, amended assessments, or capital gains events they did not plan for.

Even if your situation does not tick every box here, talk to us. We specialise in finding pathways others miss.

How does ATO debt consolidation work?

1. Assess your equity
   First, we work out how much equity you have in your property. Your total new loan (existing mortgage + ATO debt + any other debts being consolidated) needs to fit within the lender's loan-to-value ratio (LVR) limits. 80% LVR is ideal as it avoids Lenders Mortgage Insurance, but some of our lenders can go up to 90% LVR. The key is having a broker who knows which lenders are flexible.
2. Strategy with your broker
   We map out the full picture: the ATO debt amount, any other debts, your income and employment type, and your credit history. From there, we identify which lenders are the best fit and model the repayment comparison so you can see the numbers clearly.
3. Lodge the refinance application
   We prepare and submit your application to the chosen lender, including the ATO payout letter, your income evidence, and all supporting documents. We handle all lender communication and conditions on your behalf.
4. Settlement - ATO paid directly
   At settlement, the new lender pays out your existing mortgage and pays the ATO directly. You do not receive funds and then pay the ATO yourself - it is handled through the settlement process. You wake up the next day with the ATO debt gone and one clean home loan repayment.

Important detail: the ATO payout figure can change daily because the general interest charge compounds. Your broker will request the payout letter close to settlement to ensure the figure is current. Any small discrepancy is typically handled through a settlement adjustment.

Which lenders accept ATO debt?

This is one of the main reasons people come to us specifically. Most brokers do not know which lenders treat ATO debt favourably - we do, because it is what we work with every day. We handle these files daily and know exactly how to position them.

Major banks

The big four and other major banks will sometimes accept ATO debt consolidation, but they tend to ask more questions. They want to understand why the debt exists, whether it is under a payment arrangement, and whether it indicates an ongoing cash flow problem. For straightforward cases - say a one-off tax bill with a good credit history and stable income - a major bank may well approve it.

Non-major and specialist lenders

This is where most ATO debt consolidation applications end up, and for good reason. Non-major lenders have more flexible credit policies around tax debt. They are experienced in assessing these cases and can often move faster than the majors. Some key differences:

• Smaller ATO debts - some lenders are more flexible with smaller ATO debts, while larger amounts may need a specialist approach. Either way, we know which lenders to go to.
• Larger ATO debts - still very much possible, but the lender will want a clear explanation of the cause and evidence that the underlying issue has been addressed (e.g., a new accountant, updated BAS lodgements, changed business structure). This is exactly the kind of file we handle every day and know how to position.
• Multiple ATO debts - if you have both income tax and BAS/GST arrears, lenders look at the total picture. Having a tax agent actively managing your affairs is a strong positive signal

This is exactly why working with a broker who specialises in debt consolidation matters. A generalist broker may not know which lenders have appetite for ATO debt, or how to present the application in a way that gets through credit assessment. We deal with these cases every day and know exactly how to tell the right story to the right lender.

What if I have a payment plan with the ATO?

This surprises a lot of clients. They assume that having a payment arrangement with the ATO looks bad. In reality, lenders view it positively - it demonstrates responsibility and engagement. An ATO debt with no plan in place is a red flag. An ATO debt with an active payment arrangement says "this person is dealing with it."

How to set up an ATO payment plan

If you do not already have one, you can set up a payment plan:

• Online through your myGov account linked to the ATO
• By phone on 13 11 42 (ATO debt line)
• Through your tax agent - they can negotiate on your behalf and often get more favourable terms

Practical tip: even if you intend to consolidate the debt into your mortgage within a few weeks, having an active payment plan in place when the lender assesses your application makes a real difference. Set it up as early as possible, even if the repayments are modest.

We also see cases where clients have let a payment plan lapse. If that has happened to you, re-establishing the arrangement before we lodge your application is usually straightforward. Your tax agent can help, or we can guide you through it.

What about the general interest charge (GIC)?

The GIC rate is set quarterly by the ATO at the base interest rate plus 7%. It compounds daily, which means the debt grows faster than most people expect. The difference between the GIC rate and a home loan rate is substantial, and that gap is where the real savings come from.

On a typical ATO debt, consolidating into your home loan can save you thousands in interest every year. The exact savings depend on your specific situation, but the difference is significant in almost every case we see. A Loop Loans broker will model your exact numbers so you can see clearly what the saving looks like.

Beyond the interest saving, there is a cash flow benefit. ATO payment plans often require higher monthly instalments than what the same debt costs when spread across a home loan. Clients regularly tell us the monthly breathing room is just as important as the interest saving.

We handle these calculations every day and can show you exactly what the improvement looks like for your situation. That is what we do.

Can the interest on consolidated ATO debt be tax deductible?

This is one of the most overlooked advantages of consolidating ATO debt into your mortgage. With the right loan structure - typically a separate split on your home loan for the ATO debt portion - the interest you pay on that split can be claimed as a tax deduction. Compare that to an ATO payment plan, where the General Interest Charge you are paying is not deductible at all.

The combination of a lower interest rate and potential tax deductibility makes the financial case very compelling for most clients we work with. We structure these splits as part of our standard process, so this benefit is built in from day one.

Can I consolidate ATO debt if I'm self-employed?

If you are self-employed and carrying ATO debt, you are far from alone. It is one of the most common financial patterns we see: a trade or services business grows quickly, the owner reinvests in equipment or staff, and the quarterly BAS payments fall behind. Before long, the ATO debt has grown significantly and is accruing GIC daily.

The good news is that lenders who work in this space understand the cycle. They are not looking for a perfect tax history - they are looking for evidence that the business is viable and the underlying issue has been addressed. We handle these files every day and know exactly how to position them.

Income verification for self-employed borrowers

• Full-doc - if your tax returns are up to date and your declared income supports the loan, you can go through the standard pathway at the best rates
• Low-doc (BAS method) - the lender uses your Business Activity Statements to calculate annualised income, applying an industry-standard profit margin to your GST turnover
• Alt-doc (bank statements) - some lenders assess 6 to 12 months of business bank deposits to determine income, which works well for businesses with irregular invoicing cycles
• Accountant's declaration - your accountant provides a letter estimating current-year income, useful when tax returns are being prepared but not yet lodged

Even if your situation does not tick every box here, talk to us. We specialise in finding pathways others miss.

What are the risks?

Unsecured becomes secured

This is the most important thing to understand. Right now, if you cannot pay your ATO debt, the ATO can pursue you through payment arrangements, garnishee notices, or director penalty notices - but they cannot take your home. Once that debt is part of your mortgage, your home is the security. If you default on the mortgage, the lender can sell your property.

We are direct about this with every client. Consolidation is a powerful tool, but it only makes sense if you are confident you can maintain the mortgage repayments going forward. This is exactly why you need a specialist broker who looks at the full picture, not just the refinance in isolation.

Address the cause, not just the symptom

If your ATO debt built up because of a one-off event - a bad year, a late-paying client, an unexpected tax bill - consolidation is a clean reset. But if the underlying issue is ongoing cash flow management or a business that consistently cannot cover its tax obligations, consolidating the debt without fixing the root cause just delays the problem.

We ask every client: what has changed since this debt accumulated? If the answer involves a new accountant, better systems, restructured BAS management, or a change in business model, that is a strong signal. If nothing has changed, we will be honest about that too.

The key is making sure the underlying issue is addressed too. We do not just consolidate and walk away - we stay involved with regular reviews to make sure your situation keeps improving.

Longer loan term

Rolling ATO debt into a 25-year mortgage means you are technically paying it off over a much longer period than a 2 to 3 year ATO payment plan. Even at a lower rate, the total interest paid over 25 years could be more. The practical solution: make additional repayments in the early years to clear the consolidated amount faster. We model this for every client - showing the difference between minimum repayments and an accelerated strategy.

How we handle this at Loop

We do not just process the refinance and move on. Every ATO consolidation strategy we build includes a clear comparison of total interest costs (not just monthly repayments), a discussion about what caused the debt and what has changed, and where possible, a repayment structure that clears the consolidated amount ahead of schedule.

Our job is to make sure you are genuinely better off - not just in month one, but in year five. We handle these files every day and know exactly how to position them.
