| Compare | ATO payment plan | Commercial tax debt loan |
|---|---|---|
| Approval | Subject to the ATO’s assessment and terms | Subject to the lender’s policy and assessment |
| Cost | General interest charge may continue to accrue | Quoted interest or charge plus establishment and other fees |
| Repayments | Agreed instalments and continuing obligations | The lender’s repayment schedule and contract |
| Security | Check the actual ATO arrangement | May add asset security or a personal guarantee |
| Future tax | New liabilities still need funding | New liabilities still need funding alongside the loan |
Ask the ATO about the position first
Confirm the amount owed, overdue lodgements and any existing arrangement or notice. If you cannot pay in full, contact the ATO or your registered tax agent promptly. A payment plan is not automatic forgiveness, and interest can continue while the debt is paid down.
The ATO's general interest charge guidance explains that rates change quarterly and interest compounds daily (checked 5 October 2026). Use the applicable rate rather than a historical article figure, and confirm how refunds or credits affect your account.
Prepare a proposal that leaves room for new tax
Reconcile the debt by account, period and charge so you know what is overdue and what is still becoming due. Gather current lodgement status and details of any previous arrangement. An unexplained total from an old statement is a poor basis for either a payment-plan request or a refinance.
Work backwards from the cash left after ordinary business costs and upcoming obligations. If an instalment can only be met by leaving the next BAS unpaid, the proposed plan has not solved the recurring problem. Show a realistic payment amount and explain how the trading forecast supports it.
Ask the ATO or your agent what conditions apply, including continuing lodgements, later liabilities and treatment of refunds or credits. Confirm the agreed dates and method of payment against your actual account. Keep the written arrangement so you can identify any change or missed instalment promptly.
If the balance includes a disputed assessment or charge, separate that issue from the payment discussion and ask your tax adviser how each process affects the position. A dispute should not be assumed to suspend every payment or response obligation.
Account for the change to interest deductions
The ATO states that GIC and shortfall interest charge incurred on or after 1 July 2025 are no longer deductible (checked 5 October 2026). Applicable income-year rules matter for substituted accounting periods. Do not use an old comparison that assumes these charges always reduce taxable income.
That does not make every commercial refinance preferable. Ask your tax adviser about the treatment of any proposed borrowing; the purpose and circumstances matter. Compare cash cost first, then any properly established tax effect.
Compare what clears the ATO balance and what you repay
Use the ATO balance for the expected payment date, then obtain a lender quote showing the usable advance after any deducted fees. An approved amount equal to the tax balance may be insufficient if fees come out of the advance. Confirm how payment reaches the ATO and when it will be credited.
For each available option, list the instalment dates, charges and total expected outlay over the same period. Use the applicable quarterly GIC rates for the ATO side, allowing for uncertainty in future rates. Do not compare a short payment plan with a multi-year loan using the instalment alone.
Review any new security or guarantee separately from the price. A quote that appears cheaper can place an asset at risk under a new agreement. The tax account may be cleared while the business and its guarantors remain liable to the commercial lender.
Compare a cash-flow benefit with a genuine saving
Suppose an illustrative tax balance is $40,000 and a commercial lender deducts a $1,200 fee from a $40,000 advance. Only $38,800 is available to pay the account. The business needs another $1,200 or a different facility amount to clear the assumed balance, before any further charge accruing before payment. Include that funding gap explicitly.
Now compare the proposed lender schedule with the available ATO arrangement over the same period. A longer loan may lower instalments but keep the debt outstanding for more years. If the loan is secured against property, the cost comparison should sit beside the new security risk, not replace it.
Early repayment deserves its own figure where a strong seasonal receipt is expected. Ask how much would be due on that date, which charges are refundable or avoided and how security is released. The answer may change whether a short ATO arrangement or commercial borrowing fits the expected recovery.
What could justify the commercial option?
An eligible commercial offer may create a more workable repayment schedule or meet a specific funding deadline. It might also be unsuitable because of fees, frequent deductions, guarantees or an uncertain exit. Judge the actual written alternatives rather than assuming either the ATO or a lender is always the cheaper or easier creditor.
If the loan depends on a property sale or further refinance, test that exit separately. Clearing the tax account with borrowing only transfers the repayment obligation. The business needs a plan that works after the transfer, including the next tax cycle and a realistic downturn case.
Stop the next tax bill becoming another loan
Build upcoming BAS, income tax and other obligations into the forecast alongside the proposed debt payments. A business paying down old tax without funding new liabilities can quickly return to the same position.
If a formal demand or director penalty notice is involved, seek prompt advice on its deadlines and consequences. A pending application or an assumed payment plan should not be treated as having resolved the notice.
