Can Your Business Actually Afford an ATO Payment Plan? What to Check Before You Agree

When you owe money to the ATO and a payment plan is offered, it is tempting to agree quickly just to make the pressure stop.
That instinct is completely understandable. But agreeing to an ATO payment plan without first checking your numbers carefully is one of the most common mistakes small business owners make - and it can make an already difficult situation significantly harder.
This article walks through what you need to know before entering an ATO payment plan, why your bookkeeping matters more than most people realise, and how to make sure any arrangement you agree to is one your business can actually sustain.
What an ATO Payment Plan Actually Is
An ATO payment plan (formally called an instalment arrangement) allows you to pay your tax debt in regular instalments over an agreed period rather than in one lump sum.
For many small businesses, this is a genuine lifeline. Rather than having to find a large amount immediately, the debt is spread out into manageable pieces.
To set up a payment plan, you can either apply online through the ATO's business portal (for debts under $100,000) or contact the ATO directly. In most cases, you will need your lodgements to be up to date before a plan is approved - overdue BAS or tax returns generally need to be lodged first.
Interest continues to apply to the outstanding balance throughout the arrangement - the general interest charge (GIC) rate is set quarterly and is currently above 11% per annum. This is not a reason to avoid a payment plan, but it is a reason to understand the true cost of the arrangement.
The Mistake Most Business Owners Make
The mistake is not entering a payment plan. Payment plans are often exactly the right thing to do.
The mistake is agreeing to a repayment amount without first knowing whether the business can afford it - not just for the next month, but consistently, every month, for the duration of the plan. Here is why this matters:
If you default on an ATO payment plan - even once - the arrangement can be cancelled. When that happens, the full outstanding balance becomes immediately payable. The ATO is also less inclined to enter into a new arrangement with someone who has already defaulted on one.
Defaulting is worse than negotiating a lower repayment to begin with.
What You Need to Know Before You Agree
Before committing to any repayment amount, you need honest, accurate answers to these questions:
1. How much do you actually owe? Not an estimate. The actual figure - including principal debt, interest accrued to date, and any penalties. This number should come from your ATO account, not from memory.
2. Are all your lodgements up to date? As noted above, the ATO generally requires BAS and tax returns to be current before approving a payment plan. If lodgements are missing, these need to be dealt with first - and completing them may change the total debt figure.
3. What is your current cash flow position? What is actually coming into the business each month, and what are all the outgoings? This needs to include not just the obvious expenses but also upcoming obligations - next month's wages, rent, supplier invoices, and any loan repayments.
4. What are your future ATO obligations? This is the one most business owners overlook. While you are making repayments on the old debt, new BAS quarters keep coming. GST, PAYG, and superannuation still need to be paid. If the repayment plan amount does not leave room for future obligations, the debt will keep growing even while you are paying it down.
5. What buffer does the business have? Cash flow in a small business is unpredictable. A slow month, a late-paying client, an unexpected expense - any of these can put pressure on your ability to make plan repayments. Is there a margin in the plan for this?
What Happens If the Repayment Amount Is Too High
If you agree to a monthly repayment you cannot sustain, one of two things happens:
You default, the plan is cancelled, and the full debt becomes payable.
Or you keep making the payments, but you stop paying other obligations - wages, superannuation, suppliers - and the business gets into deeper trouble from a different direction.
Neither outcome is good. Which is why it is worth taking the time to get the number right before you commit.
The ATO will sometimes negotiate on repayment amounts - particularly if you can demonstrate, with real financial records, what the business can realistically afford. A payment plan based on accurate bookkeeping is a much stronger negotiating position than one based on a rough estimate.
The Role of Bookkeeping in Getting This Right
Accurate, up-to-date bookkeeping is the foundation of everything described above.
You cannot accurately answer any of the questions in the previous section without clean financial records. If your bank accounts have not been reconciled, if your income and expenses are not correctly categorised, if your GST and PAYG figures are unclear - then any cash flow assessment you do is based on guesswork.
And in a payment plan negotiation, guesswork is expensive. When your bookkeeping is current, you can:
Pull an accurate profit and loss statement and balance sheet showing real income and expenses and the working capital position of the business
See exactly what cash is coming in and going out each month
Identify upcoming BAS and tax obligations
Show the ATO (or your accountant) a clear picture of what the business can afford
Make a repayment commitment with confidence rather than hope
This is the difference between a payment plan that works and one that collapses.
Working With Your Accountant and Bookkeeper Together
An ATO payment plan is not just a financial decision. It is a business decision - one that affects your cash flow, your operations, and your relationship with the ATO for months or years.
Your bookkeeper's role is to make sure your records are accurate and your financial position is clear. Your accountant's role is to advise on the tax implications and help you negotiate with the ATO where needed. For complex situations - significant debt, penalties, Director Penalty Notices, or w,here the ATO has already escalated - a specialist tax debt adviser may also be needed and a good bookkeeper should be able to refer you to one of these people.
Having these three people working from the same accurate set of numbers is the most effective way to reach a resolution that works for your business.
Before You Call the ATO
If you know you need to enter an ATO payment plan and you have not yet made that call, now is the right time to act - but do not do it without your numbers in order.
The steps to take first:
Get your bookkeeping up to date and your bank accounts reconciled
Pull a current profit and loss statement and cash flow summary
Confirm which BAS periods are outstanding and get those lodged
Calculate what monthly repayment your business can genuinely sustain - including future tax obligations
Talk to your accountant before agreeing to any amount
This preparation takes time. But it is far less costly than entering a plan you cannot maintain.

Frequently Asked Questions About ATO Tax Debt
How do I set up an ATO payment plan for my business?
For debts under $100,000, you can apply for a payment plan online through the ATO's business portal (myGov or Online services for business) without needing to call. For larger debts or more complex situations, you will need to contact the ATO directly on 13 11 42. Before applying, make sure all lodgements are up to date - the ATO generally requires this before approving an arrangement.
Does interest still apply during an ATO payment plan?
Yes. The general interest charge (GIC) continues to accrue on the outstanding balance throughout the payment arrangement. As of 2025, the GIC rate is above 11% per annum, calculated daily. This means the sooner you reduce the principal balance, the less interest you pay overall. Some business owners choose to pay more than the minimum instalment where cash flow allows.
What happens if I miss a payment on my ATO payment plan?
Yes. For purchases over $82.50 (including GST), you must hold a valid tax invoice from a GST-registered supplier to claim the input tax credit. A valid tax invoice must include the supplier's ABN, a description of the goods or services, the GST amount or a statement that GST is included, and the date. Claiming credits without valid invoices is a common BAS audit trigger.
How do I check if a supplier is registered for GST?
You can check any ABN on the Australian Business Register at abr.business.gov.au. If a supplier is not registered for GST, no GST is included in their invoice and no credit can be claimed, regardless of what the invoice says.
Can I amend a BAS after it has been lodged?
Yes. You can lodge a BAS amendment if you discover an error after lodgement. Amendments can be lodged through the ATO's online services or through your registered BAS agent. If the error resulted in underpayment, interest may apply on the difference. If you overpaid, you may be entitled to a refund.
How often do I need to lodge BAS?
Most small businesses lodge quarterly. Businesses with a GST turnover of $20 million or more must lodge monthly. You can also choose to lodge monthly voluntarily. The ATO notifies you of your lodgement frequency when you register for GST, and this can be changed by contacting the ATO if your circumstances change.
What is the difference between a BAS and an IAS?
A Business Activity Statement (BAS) is lodged by businesses registered for GST and includes GST, PAYG withholding, and sometimes PAYG instalments. An Instalment Activity Statement (IAS) is lodged by businesses not registered for GST but who have PAYG withholding or instalment obligations. If you are registered for GST, you will lodge BAS rather than IAS.
