ATO payment plan vs business loan: an honest side-by-side comparison

Why is this comparison usually done badly?

Most pages about this question are written by someone with a side to sell. Lenders tend to dismiss payment plans in a sentence. Advisers tend to treat borrowing as reckless. Neither helps you decide. Here is the comparison as fairly as we can make it — and yes, we’re a funder, so you should check our reasoning with your accountant.

What are the real differences?

Factor	ATO payment plan	Business loan
Set-up cost	Free	Loan fees vary — ask for them in writing
Ongoing cost	GIC, compounding daily, rate reset quarterly	The loan’s interest and fees over its term
Deductibility	GIC incurred from 1 July 2025: not deductible	Interest may be deductible — ask your accountant
Who you deal with	The ATO	A lender
Flexibility to change	Can’t change online beyond 24 months; renegotiate with the ATO	Depends on the lender’s terms
What triggers trouble	A missed instalment, an ignored arrears letter, or new tax not paid on time	Missed repayments under the loan contract
Consequence of default	Whole overdue balance due immediately; firmer action may follow	The lender’s arrears and recovery process
Director penalties	Not remitted by a plan	Payment of the company liability remits them, including lockdown amounts
Credit reporting	Not disclosed while you comply	Removed once the debt is paid
Security	Usually none; secured plans exist for larger debts	Property for secured loans; personal guarantees common
Speed	Online plans are immediate for debts under $200,000	Property-secured funding possible in as little as 24 hours

How do you compare the cost without a published rate?

You need three numbers, all of which you can get today:

1. The ATO balance, from your statement of account.
2. The current GIC rate, from the ATO’s GIC rates page. The ATO resets it each quarter.
3. A written loan quote showing the total of all repayments and fees.

Then estimate the GIC over the plan term you’d realistically need, remembering it compounds daily on the reducing balance. Compare that with the loan’s total cost over its term. Finally, ask your accountant how each would be treated for tax — GIC from 1 July 2025 isn’t deductible; loan interest may be.

Our payment plan vs loan tool does the GIC arithmetic for you with the rate you enter. It doesn’t fill in any rate on your behalf.

When does a payment plan usually win?

• The debt is modest and can be cleared within a year or so.
• You qualify for the interest-free plan — that’s hard to beat.
• The debt is mostly income tax, which isn’t covered by director penalties.
• The business can comfortably meet instalments and new tax.
• You have no property and an unsecured loan would mean very high repayments.

When does a loan usually win?

• A lockdown director penalty applies. Only payment removes it.
• A standard DPN has arrived and paying within 21 days is the only outcome that keeps you in control.
• The debt is large and a plan would run for years with GIC compounding throughout.
• The ATO has refused or defaulted a plan and the whole balance is due.
• A garnishee notice is taking a share of your takings.
• You want certainty: one fixed repayment and no further ATO action.

What risks apply either way?

Both options fail in the same circumstance: when the business keeps adding new tax debt faster than it pays the old. If that’s happening, fix the cause first — pricing, costs, a tax set-aside account, monthly BAS reporting. Otherwise a plan will default and a loan will be followed by a new ATO debt on top of it.

And if the business can’t sustain any repayment, neither option is right. That’s a moment for the free Small Business Debt Helpline (1800 413 828) or a registered professional you’ve checked.

What does a fair side-by-side look like? (illustrative)

Here’s how to set out a comparison on paper. The figures are placeholders — replace them with your own ATO balance, the ATO’s current published GIC rate and a real written loan quote.

Line	ATO plan	Loan
Amount owed to the ATO today	Your balance	Your balance (paid out at settlement)
Term	The plan length you’d realistically need	The loan term
Estimated interest / cost	GIC over the plan (daily compounding at the current quarterly rate)	Total of all repayments and fees, less the amount borrowed
Deductible?	No, for GIC incurred from 1 July 2025	May be — ask your accountant
After-tax cost	Same as above	Adjusted for any deduction
Director penalty exposure	Remains until paid	Removed on payment
What happens on a missed payment	Default; whole balance due	Lender’s arrears process

Our payment plan vs loan tool works out the GIC line for you. Your accountant can complete the after-tax lines.

Questions to ask yourself before deciding

• Could the business meet the plan instalments and every new BAS for the whole plan term?
• Is any of the debt locked down for director penalty purposes?
• Has a plan defaulted before, and what’s different now?
• How would a garnishee notice or credit listing affect suppliers and customers?
• Is there property you’re comfortable using as security?

Honest answers usually make the choice obvious.
