Business loan or ATO payment plan: which way out of a tax debt costs less?

The letter from the ATO usually lands at the worst possible moment, and the first instinct is to ring and ask for time. That’s often exactly the right move. But the arithmetic behind “just go on a payment plan” changed in 2025, and two more shifts arrive before the end of 2026. Here’s an even-handed look at when the ATO’s own arrangement is the smarter choice and when a commercial loan earns its place.

Three changes that reshaped this decision

ATO interest lost its tax deduction. Any GIC or shortfall interest the ATO levies from 1 July 2025 onwards is now outside the deductions list, and that applies even when the underlying debt belongs to an earlier income year. For years, owners treated a payment plan as cheap finance partly because the GIC came back to them at tax time. That’s gone.

Card payments to the ATO are ending. From December 2026, a credit card is no longer a way to pay the ATO; the final day for card payments is 30 November. Anyone whose plan instalments are charged to a card, or who planned to pay a lump sum by card and roll it on, needs another arrangement.

The credit reporting line is live. When an ABN holder lets $100k or more sit overdue for longer than 90 days without engaging, the ATO can report that debt to credit bureaus. A listed debt follows the business into every future application, including with its own bank.

	ATO payment plan	Business loan
Setting it up	Online for many business debts under $200k; by phone above that	An application to a bank, non-bank or private lender
Speed	Often same day if you qualify online	Same day to a few weeks, depending on the lender and security
Cost in dollars	GIC accrues daily and compounds; not deductible	Interest plus fees; interest generally deductible for business borrowing
What the ATO sees	An ongoing debt being managed	A cleared account
Conditions	Keep up instalments, lodge on time, pay new liabilities as they fall due	Make loan repayments; the ATO account is closed
If things go wrong	Plan can be cancelled, and the ATO can escalate to garnishees or director penalties	The lender enforces its security or guarantee
Security	None	None for smaller unsecured loans; property for larger or harder cases
Credit file	Unaffected while you’re engaging	A new credit enquiry and an account

When the payment plan wins

• The debt is modest and the runway is short. A five-figure BAS shortfall you can clear over a few months rarely needs a lender involved.
• Your cash flow is steady. If instalments sit comfortably beside wages, rent and next quarter’s BAS, a plan is low-friction.
• You’d struggle to qualify elsewhere. The ATO doesn’t run a credit check to agree a plan, and a business with patchy credit can still get one.
• You want no new debt on the books. No guarantee, no security, nothing registered on the PPSR.
• You’re sorting out a dispute. If part of the debt is under objection, keeping the rest on a plan while the review runs can be the tidy option.

When the business loan wins

• The ATO wants more upfront than you have. After a previous default, the ATO commonly asks for a sizeable lump sum before a new plan. A loan can fund that sum or clear everything.
• The debt is large or escalating. Garnishee notices, director penalty notices and the threat of credit reporting make speed worth paying for. See our guide to an ATO garnishee notice.
• The instalments would choke the business. The ATO’s preferred terms are often shorter than a commercial loan’s. Spreading over a longer term can protect payroll and stock.
• The total cost is lower. With GIC now non-deductible, a loan whose interest is deductible can come out cheaper after tax, particularly for larger debts held over a year or more.
• You want the ATO relationship reset. A cleared account helps with future plans, refunds being withheld, and bank applications that ask about tax debt.

How to compare the dollars properly

Rates aren’t quoted in this directory, and the GIC rate moves each quarter, so do the comparison in dollars using today’s figures.

An illustrative building supplies company owes $140k across GST, PAYG withholding and company tax. It can afford roughly $9k a month without trimming staff.

• Payment plan. At $9k a month the debt takes well over a year to clear once GIC keeps accruing on the shrinking balance. Use the ATO debt calculator to estimate the total GIC, then remember none of it is deductible.
• Unsecured loan over two years. Ask the lender for the total repayable. Subtract $140k for the cost in dollars, then ask your accountant how much of the interest the company can deduct.
• Property-secured loan over three years. Higher setup costs (valuation, legals, establishment fee), but often fewer dollars per year and lower monthly repayments.

Put the after-tax figures side by side. In some cases the plan still wins comfortably. In others, the loan comes out ahead once the deduction is counted, and the business stops worrying about default notices too.

The hybrid most owners overlook

It isn’t always one or the other. The ATO tracks income tax and activity statement debts in separate accounts, which opens up combinations:

1. A small loan funds the upfront payment the ATO wants, and the rest stays on a plan.
2. A loan clears the larger or older account, and the smaller one runs on a plan.
3. A line of credit sits beside the plan to cover the next BAS, so the plan never defaults because of a bad month.

Our page on tax debt loans explains which lenders pay the ATO directly at settlement, and paying a tax bill walks through sizing the amount.

Where banks fit

If your bank will lend to clear the debt, take that offer seriously: banks are often the cheapest money around. They tend to be comfortable when the debt is small, the plan is current and the business is profitable. Where they step back is larger overdue debts, recent defaults or unlodged returns. That’s the territory covered in ATO tax debt business loans, where non-bank and private lenders do much of the work.

A five-question checklist

1. Can you meet the ATO’s instalments and every new BAS on top? If not, a plan may fail, and a failed plan costs more than a loan.
2. Have you defaulted on a plan before? Expect tougher ATO terms; read funding an ATO payment plan default.
3. Are you near the $100k, 90-day disclosure line? Engaging now, by plan or by payment, matters.
4. What’s the after-tax dollar cost of each option? Get your accountant to sign off the deduction assumptions.
5. Are lodgements up to date? Neither the ATO nor a lender will move far while returns are outstanding.

Clearing the ATO and getting back to work

Tax debt is a routine part of what we deal with, and it doesn’t put us off. Some owners need a plan, some need a loan, and plenty need a bit of each, so the first job is a clear picture of the debt and the cash flow around it. Our enquiry form takes a minute or so to complete, and making it won’t trigger any check on your credit report. It goes to our own team rather than being broadcast to every lender in the market. A real specialist reviews it before ringing you. Please be upfront about the amount owing, what’s lodged and any notices received; accurate details help us land on the right path straight away.
