Tax debt business finance: matching the fix to the date

Which tax debt is it, and when did it fall due?

“Tax debt” covers several different bills, and each one has its own clock. Before choosing between a payment plan and finance, write down what makes up the balance on your ATO statement of account:

Component	Typical due date	Why it matters
GST on your BAS	28th of the month after the quarter (21st for monthly)	Largest single item for many businesses
PAYG withholding	With your BAS	Money held for employees; carries director penalty exposure
PAYG instalments	Quarterly, 28 days after quarter end	Prepayment of income tax
Income tax	After assessment	Can arrive as one large bill
Super guarantee charge	On assessment	Only if super was paid late

The split matters because the consequences are different. Withheld PAYG and unpaid super sit closest to personal risk for directors, so they’re usually cleared first. GST and income tax still accrue interest, but the pressure is different. If the balance jumped after a return or an amendment, see unexpected tax bill.

When is a payment plan enough?

The ATO says businesses owing $200,000 or less may be able to set up a payment plan through online services, which is quick when it fits. A plan can make sense when:

• the debt is modest compared with your cash flow;
• you’re confident of meeting every instalment alongside new BAS amounts as they fall due; and
• nothing else is waiting on the tax debt being cleared — for example, another lender who won’t proceed while it’s outstanding.

The ATO’s alternative payment plan page also describes interest-free arrangements over 12 months for some small businesses (turnover under $2 million, activity statement debts of $50,000 or less, overdue for up to 12 months). Check whether you fit before you borrow.

The catch with standard plans is interest. The ATO confirms that tax debts on a payment plan keep accruing general interest charge, which compounds daily, and ATO interest incurred on or after 1 July 2025 can no longer be claimed as a tax deduction. A long plan on a large balance can quietly become expensive.

When does funding the tax debt make sense?

Funding tends to come into its own when:

1. The plan defaulted. The ATO says a missed instalment can default the plan and make the full overdue balance payable. See missed ATO payment plan instalment.
2. The debt is large or growing. Daily compounding on a big balance adds up, and once reporting thresholds come into view, the debt starts to affect how others see your business.
3. The debt blocks other plans. A tax balance can hold up a refinance, a new facility or a purchase. Clearing it can unlock the bigger picture.
4. You want one repayment instead of two. A new BAS every quarter on top of plan instalments is a lot to juggle; one structured facility can simplify it.

On reporting: the ATO can disclose a business’s tax debt to credit reporting bureaus when at least $100,000 is overdue by more than 90 days, the business has an ABN, and it isn’t engaging with the ATO. Engaging early — including arranging finance — keeps you on the right side of that line.

Secured or unsecured for a tax debt?

For most tax debts above a modest size, property security gives the most room. Property-secured loans run from $20,000 to $5,000,000 over residential or commercial property; $20k to $250k is possible same day and up to $5m is possible within 24–48 hours. Unsecured and cash-flow options, typically $5,000 to $500,000, can cover smaller tax bills for trading businesses with steady bank statements. ATO debt is considered case by case either way. Compare the two in secured or unsecured when time is short, or start the enquiry and we’ll look at it with you.

An illustrative example

Illustrative only. An electrical contractor owes $148,000 — two quarters of GST and withheld PAYG — after a large builder paid late. A payment plan was set up but defaulted when the next BAS landed on top of it. The director owns a home with good equity and the business has steady work booked.

Rather than try to reinstate a plan while carrying the new quarter as well, the director uses a property-secured loan to clear the full balance and the current BAS together. The withheld PAYG is gone, the daily interest stops, and there’s one repayment to manage while the builder’s money comes in.

What to do before the next due date

• Lodge on time, even if you can’t pay. The ATO recommends calling before the due date if you can’t lodge or pay.
• Get your statement of account from online services so the number is exact.
• Separate withheld PAYG and super from the rest — clear those first.
• Don’t let a plan quietly default. If an instalment is at risk, call the ATO before it’s missed.

Deal with the tax debt — see where you stand

Tax debt is one of the most common reasons people come to us, and we’d rather help you clear it than watch interest compound. Tell us the balance, what it’s made of and any date the ATO has given you. Asking doesn’t run a credit check, your details stay with one team instead of being passed to a queue of lenders, and a real person works through your situation and calls you. Fill the form in accurately — especially the total owed and any property — so we can match the right option first time.
