Quick answer

A business tax bill can be paid from cash, through an ATO payment arrangement, or with a short-term loan. Borrowing makes sense when the shortfall is a timing problem and the business can repay; it makes less sense when tax money is being spent every quarter. ATO debt is considered case by case, and unsecured funding is typically $5,000 to $500,000.

Key points

  • Contact the ATO early; business.gov.au points owners with unpaid tax to 13 11 42.
  • Borrowing suits a timing problem; a payment plan may suit a larger, slower one.
  • ATO debt is considered case by case by lenders; a plan in good standing helps.
  • The lasting fix is a set-aside habit, not repeated borrowing.

Tax has a way of arriving on a date that suits nobody. The income tax bill after a strong year, the BAS after a fast quarter, a PAYG instalment that has crept up with turnover. When the cash that should be there is somewhere else, owners start asking whether borrowing to pay the ATO is smart or desperate. It can be either.

What kinds of tax bill cause trouble?

Four come up most often.

  1. The BAS, carrying GST, PAYG instalments and possibly PAYG withholding. See BAS and GST cash-flow loans.
  2. The income tax assessment, which can be large after a profitable year.
  3. PAYG instalments, which business.gov.au explains as prepayments towards income tax, and which can step up as your income grows.
  4. Super and PAYG withholding, which are held on behalf of others and have to be paid over.

Business.gov.au says that if you have unpaid tax or super, you should contact the ATO on 13 11 42.

Should I pay with a loan or an ATO arrangement?

Both can be reasonable. The choice rests on the cause and the cost.

Question Leans towards a loan Leans towards an ATO arrangement
Why can’t I pay? Timing: money is owed to me and will land soon The bill is bigger than a short bridge can sensibly cover
Can the business repay a lender? Yes, comfortably Only slowly
How long do I need? Weeks to a few months Longer
What are the consequences of delay? Penalties, pressure Managed through the arrangement

Call the ATO first, before the due date if possible. Business.gov.au advises contacting creditors early, explaining your circumstances and asking about extensions, partial payments or a payment plan, and keeping a record of every conversation. After that, consider whether a loan or an arrangement leaves the business healthier. Your accountant should help you compare.

When does borrowing to pay tax make sense?

It tends to fit when:

  • a big customer is late and the invoice will land within weeks;
  • a growth spurt inflated this quarter’s GST and PAYG;
  • paying on time protects the business from penalties and keeps lodgements clean;
  • the loan can be repaid from normal trading without choking wages.

It fits poorly when the business has spent the tax money three quarters in a row, because a loan will only add repayments to the same habit. If that is you, fix the habit first, using the tax-dough jar guide.

How do lenders see ATO debt?

ATO debt is considered case by case. A lender reading your application wants to know:

  • Is the business trading now, and are the statements healthy?
  • Are your lodgements up to date?
  • Is there a payment plan, and are you keeping to it?
  • What caused the debt, and has it been addressed?

A plan that is up to date is evidence of good faith. An unaddressed debt with silent lodgements is a red flag. Our page on bad-credit business loans goes into more detail.

For trading businesses, unsecured funding is typically $5,000 to $500,000, sized on turnover and bank statements. Same-day funding is possible for smaller unsecured amounts when the paperwork is in order. Property-backed funding from $20,000 to $5,000,000 may suit larger tax debts if you own property.

What does it cost, beyond the debt itself?

Add up the total cost of the finance in dollars, any fees, and what the repayments do to your weekly cash. Business.gov.au notes that non-bank lenders can cost more than banks while offering more flexible criteria, so go in with eyes open. Compare that total with the cost of the alternative, whether it is an arrangement with the ATO or paying from cash and thinning your working capital.

What stops this happening again?

A set-aside habit. Every time money lands, a fixed slice goes into a separate account for GST, PAYG and super. The slice is not touched. In practice that means:

  1. Decide the slice with your accountant, based on your actual obligations.
  2. Move it the day the money arrives, not at the end of the month.
  3. Treat the account as the ATO’s money, because it is.
  4. Review the slice every quarter as turnover changes.

What should I bring to the conversation?

Whether you speak to the ATO, your accountant or a lender, preparation helps. Gather:

  • your latest BAS, assessment or notice showing the amount and due date;
  • your ATO account balance and any current payment arrangement;
  • recent business bank statements;
  • a short note on why the bill is hard to pay;
  • your expected cash position over the next two or three months.

With those in hand, the discussion gets practical quickly. You can show what you owe, what you can pay, when more cash arrives and what gap remains. That gap is the number that any funding has to cover, and it is nearly always smaller than the bill itself.

Next step

If a tax bill is close and cash is short, tell us about it. Share the amount, the due date, why the cash isn’t there and whether you have an arrangement with the ATO. A lending specialist reads the enquiry and rings you. There is no credit check just to ask, and your details are not sent out to a pile of lenders.

Honest, accurate answers are the quickest route: the real figures, the real dates, and the real story. See if you qualify before the date passes.

Frequently asked questions

Can I borrow money to pay the ATO?

Yes, tax is a common business cash-flow purpose. Whether it is sensible depends on why the bill is hard to pay and whether the business can carry the repayments.

Is a payment plan better than a loan?

Sometimes. The ATO can agree payment arrangements, so speak to them directly. A loan can still make sense if it settles the debt cleanly and the business can repay. Compare the total cost and the consequences of each.

Will ATO debt stop me getting funding?

Not automatically. ATO debt is considered case by case. Lenders look at current trading, whether lodgements are up to date and whether there is a plan for the debt.

What if I'm behind on lodging as well?

Catch up on lodgements first if you can. Overdue lodgements raise more questions than a debt with an active plan.

Where can I get free help with a business debt?

Business.gov.au lists the free Small Business Debt Helpline on 1800 413 828 and the ATO on 13 11 42 for unpaid tax or super.
