When the ATO assesses your tax return and determines that you owe money, they will issue a Notice of Assessment outlining the amount due and the deadline for payment. In most cases, you are required to pay the full amount within 21 days from the date on the notice. This three-week window is standard for most taxpayers and applies to income tax, business tax, and other obligations unless you have an existing arrangement with the ATO.
Paying your tax debt within this timeframe will help you avoid additional charges, penalties, and interest fees that can make the total debt significantly higher. If you fail to pay on time, the ATO will begin adding interest to your outstanding balance, which continues to accrue daily.
If you can afford to pay in full by the due date, this is always the best option. Clearing the debt quickly means no extra costs. If you cannot pay the full amount immediately, it is still advisable that you contact the ATO as soon as possible to discuss alternative payment arrangements. They provide payment plans that allow you to pay off your debt in smaller, more manageable instalments over time, giving you more flexibility.
Consequences of Late Payment
If you don’t pay your tax debt by the due date, the ATO may;
Apply a General Interest Charge (GIC) – This is interest added to your unpaid tax debt, which compounds daily, increasing the total amount you owe.
Contact you for payment – The ATO will reach out through SMS, letters, or phone calls to remind you of the overdue amount and discuss payment options.
Offset future tax refunds – Any future tax refunds or credits you are eligible for may be used to reduce your outstanding debt.
Initiate legal action – Continued non-payment can lead to more severe actions, such as legal proceedings, which could result in bankruptcy or liquidation, depending on your circumstances.
Setting Up a Payment Plan
If you are unable to pay your full tax debt within the standard 21-day period, contact the ATO before the due date to help you set up a payment plan that can help you manage the repayments without excessive financial strain. These payment arrangements can be set up online, through the ATO’s automated phone service, or by speaking directly with an ATO representative.
How Payment Plans Work
Tailored to Your Financial Situation
The ATO will consider your income, expenses, and financial commitments when structuring a payment plan. This ensures that the repayment schedule is realistic and that you can keep up with the payments without falling behind on other essential expenses.
Automated or Negotiated Plans
If your debt is under $100,000, you may be eligible to set up a payment plan online using the ATO’s self-service options. However, if your financial situation is more complex or you owe a larger amount, you may need to speak directly with the ATO to negotiate a customised plan.
Payment Frequency and Duration
Payment plans can be weekly, every two weeks, or monthly, depending on what works best for you. The total duration of the plan depends on how much you owe and how much you can afford to pay each instalment.
General Interest Charge (GIC) Still Applies
Even though a payment plan allows you to pay over time, it is important to remember that the General Interest Charge (GIC) will continue to accrue on the outstanding balance. This means that the longer you take to pay off your debt, the more interest you will owe. If possible, making larger or more frequent payments can help reduce the overall interest cost.
Factors Affecting Payment Terms
The duration and terms of a payment plan with the ATO are not the same for everyone. They are influenced by several key factors, including your past compliance with tax obligations, the total amount owed, and your financial situation.
Your Payment History
Your past behaviour in meeting tax obligations can significantly impact the flexibility of the payment plan the ATO offers. The ATO considers whether you have;
- Paid taxes on time in the past – If you have a history of paying your taxes on time, the ATO may be more lenient in granting longer or more flexible payment terms.
- Defaulted on previous payment plans – If you have previously failed to meet agreed repayment schedules, the ATO may require stricter conditions, such as shorter repayment periods or higher instalment amounts.
- Regularly lodged tax returns – Keeping up to date with tax lodgements shows responsibility and may make it easier to negotiate favourable terms.
If you have a strong compliance record, the ATO is more likely to approve longer repayment periods and lower minimum instalments. However, if you have previously missed payments or failed to lodge tax returns on time, they may require more frequent payments or additional security.
Amount Owed
The size of your tax debt directly affects how the ATO structures your repayment plan. Smaller debts are generally easier to manage and may be eligible for automated payment, while moderate debts may require a more detailed discussion with the ATO to set up a repayment plan based on your income and financial commitments.
Large debts often require additional security or financial disclosures before approval. The ATO may ask for detailed financial statements, proof of income, and expense breakdowns. In some cases, they may even request a second mortgage on a property or a personal guarantee to secure the debt.
Larger debts may also be subject to stricter conditions, such as shorter repayment terms or higher minimum monthly payments to ensure the debt is cleared as quickly as possible.
Financial Circumstances
Your ability to repay the debt is another key factor in determining your payment plan terms. The ATO assesses;
- Your income – If you have a stable and high income, you may be expected to make larger or more frequent payments.
- Your expenses – The ATO takes into account necessary living expenses, such as rent, mortgage payments, and utility bills, to ensure your repayment plan is realistic.
- Your assets and liabilities – If you own valuable assets, such as property or investments, the ATO may expect you to use them to help settle your debt more quickly.
If you are experiencing financial hardship, the ATO may offer more lenient terms, such as lower instalment amounts or extended repayment periods. However, they will likely require proof of your hardship, such as bank statements or income details.
Additional Considerations
Business owners vs. individuals – If you owe tax as a business owner, the ATO may require additional documentation, such as business financial reports, before approving a payment plan.
Bankruptcy risk – If the ATO believes you are at risk of bankruptcy, they may take more aggressive steps, such as initiating legal action to recover the debt.
How to Improve Your Payment Terms
Here are some tips to increase your chances of securing a favourable repayment plan;
- Stay compliant – Ensure all your tax returns and BAS lodgements are up to date.
- Show financial responsibility – If possible, make an initial lump-sum payment to reduce the total amount owed.
- Provide accurate financial information – Be transparent about your income, expenses, and liabilities to demonstrate what you can realistically afford.
- Avoid missing payments – If you commit to a repayment plan, stick to it to maintain a good compliance record for future negotiations.
When to Seek Professional Help
While many individuals can manage a standard ATO payment plan on their own, seeking professional help is advisable if;
- Your tax debt is large or continues to grow due to interest charges.
- You are struggling financially and cannot afford the standard payment plan.
- You have missed multiple payments or defaulted on a previous arrangement.
- You are at risk of legal action, such as garnishee orders or asset seizure.
- You need to apply for interest or penalty remission and require a strong case to support your request.
- You run a business and have complex tax obligations, such as unpaid GST or PAYG withholding debts.
If you decide to work with a tax professional, make sure they are qualified to provide credible tax advice. Look for professionals who specialise in dealing with tax debts and ATO payment plans to ensure they are capable of negotiating effectively on your behalf. A qualified professional should take the stress out of dealing with the ATO, helping you secure a manageable payment plan while protecting your financial future.
Conclusion
The ATO generally expects payment within 21 days, but if you are unable to pay in full, you can set up a payment plan to spread the cost over time. However, note that interest charges will continue to apply, so it is best to pay off your debt as soon as possible.
If you ignore your tax debt, the ATO may take further action, such as charging additional interest, offsetting future tax refunds, or even initiating legal proceedings. If you are struggling financially or with setting up the ATO tax debt payment, seek professional help from a tax or financial professional. They can negotiate better terms, help you avoid serious consequences, and take the stress of the entire process off your shoulders.
