Incurred a Tax Debt? Here’s What You Need to Know

Key takeaways

• Confirm the debt is correct and understand what it relates to.
• Act quickly. Interest and penalties can add to what you owe, and the Australation Taxation Office (ATO) may take further steps to recover the debt.
• If you can’t pay the full amount, the ATO may let you set up a payment plan that fits your cash flow.
• A tax agent can help you review your situation, talk to the ATO for you, and help you stay on track in the future.
• Keep clear records of correspondence and payments to avoid misunderstandings.

Confirm what the debt is for

Begin by asking: what is the debt, and how did it happen?

For small businesses, tax debts often come from:

• BAS liabilities (GST, PAYG withholding, PAYG instalments)
• Income tax (including unexpected taxable profit)
• Super guarantee issues
• Penalties or interest due to late lodgement or late payment

Review your ATO notice or statement carefully and check:

• The period (which quarter or financial year)
• The type of tax involved
• Whether interest and penalties have been added
• Whether any credits (such as previous payments or refunds) have been applied correctly

Mistakes can happen. Maybe a deduction was missed, income was reported incorrectly, or records were incomplete when you lodged your return.

If needed, you might be able to fix a return or object, depending on your situation.

Don’t ignore ATO debt notices

Ignoring the notice usually makes things worse. If you don’t pay the debt, the ATO may:

• Apply interest charges and penalties (which increase the balance)
• Offset future refunds against the debt
• Escalate to debt recovery action where there’s ongoing non-payment and limited engagement

The ATO is more helpful when you take action early. Even if you can’t pay right away, getting in touch quickly can reduce the risk of things getting worse.

Consider your payment options

If you can’t pay the full amount now, you still have options. The key is to act early and propose a plan your business can stick to.

Pay in full if you can

If your business has the funds, paying sooner can reduce ongoing interest charges. If you can’t pay it all, even a partial payment can help reduce the balance and interest over time.

Set up a payment plan

The ATO may agree to a payment arrangement where you repay the debt over time (weekly, fortnightly, or monthly). In most cases, you’ll need to show that:

• Your business can meet the repayments, and
• You’ll stay up to date with future lodgements and payments

When making a payment plan, base your repayments on your actual cash flow, not the best-case scenario. If your plan is too ambitious, it can fall apart and put you back at the start.

Be careful with “business-critical” obligations

For many small businesses, the most common and risky debts are GST and PAYG withholding, since these can keep growing each quarter. If your BAS debts are adding up, your plan should cover both the existing debt, and your ongoing quarterly obligations

Address the root cause to prevent repeated debt

Once you have a plan for your current debt, set up controls so you don’t end up in the same situation again.

Common fixes that work well for small businesses include:

• Setting aside a percentage of income into a separate “tax” account
• Reviewing your PAYG instalments so you’re not underpaying during the year
• Improving bookkeeping so BAS and tax estimates are more accurate
• Checking your pricing and margins (especially if GST and tax bills are consistently catching you out)

Even small changes can make a difference, especially for businesses with seasonal income or uneven cash flow.

Get professional support if you need it

A registered tax agent can help you manage tax debt with less stress and fewer errors. They can support you by:

• Confirming whether the debt is correct and complete
• Preparing amendments (where appropriate)
• Helping you propose a realistic payment plan
• Communicating with the ATO on your behalf
• Setting up systems so you stay compliant moving forward

If your business is behind on BAS lodgements, payroll, or record-keeping, getting help early can prevent the debt from growing.

Keep good records and stay organised

Always keep clear records of everything you send to and receive from the ATO. If you set up a payment plan or object to a debt, keep track of deadlines, approvals, and payments. Good records help avoid confusion and keep you in control.

A tax debt can feel overwhelming, but if you act quickly, know your obligations, and get professional help, you can manage it. The sooner you deal with it, the easier it is to fix and move on with confidence.
