How to Set Up an ATO Payment Plan in 2026

If your business owes the ATO money — whether it's a BAS debt, income tax shortfall, or overdue super — ignoring it is the worst thing you can do. The ATO charges General Interest Charge (GIC) daily, and debts can escalate into Director Penalty Notices. The good news? Setting up a payment plan is straightforward and stops enforcement action in most cases.

1. When Should You Request a Payment Plan?

Don't wait until the ATO sends a warning letter. Request a plan as soon as you know you can't pay in full by the due date. Common scenarios include:

• BAS debt after a strong quarter — you collected GST but spent the cash on operations.
• Income tax bill after lodgment — your tax return shows a larger-than-expected liability.
• Super guarantee shortfall — you missed the quarterly deadline and now owe the Super Guarantee Charge (SGC).
• PAYG instalment catch-up — your business grew faster than your instalment rate predicted.

2. How to Set Up a Plan Online

For debts under $200,000, you can set up a plan yourself through the ATO's online services:

1. Log in to your myGov account (linked to ATO) or use your myGovID via the ATO Business Portal.
2. Navigate to Accounts and Payments → Payment Plans.
3. Select the debts you want to include in the plan.
4. Choose your instalment amount and frequency (weekly, fortnightly, or monthly).
5. The system will calculate the end date and total interest payable.

For debts over $200,000 or complex situations, you'll need to call the ATO or have your registered tax agent negotiate on your behalf. We handle this for clients regularly.

3. Interest Rates and Penalties

The ATO charges General Interest Charge (GIC) on all outstanding debts, including those on payment plans. The GIC rate is updated quarterly and is typically around 7–11% per annum, compounded daily.

On a $50,000 debt, that's roughly $5,680 in interest per year. The faster you pay, the less interest accrues.

4. What Happens If You Default?

If you miss a payment plan instalment, the ATO may:

• Cancel the plan and demand immediate payment of the full balance.
• Issue a Director Penalty Notice (DPN) — making you personally liable for company tax debts.
• Apply garnishee notices to your bank accounts or customers.
• Lodge a creditor's statutory demand — the first step toward winding up your company.

If you're struggling to meet the plan, contact the ATO before you miss a payment to renegotiate. They're far more accommodating when you're proactive.

5. Tips to Avoid Future ATO Debts

• Set aside GST and PAYG weekly into a separate bank account. Don't treat collected tax as cash flow.
• Lodge on time, even if you can't pay — late lodgment penalties are separate from and additional to the debt.
• Review your PAYG instalment rate quarterly. If your income drops, vary the rate down to avoid overpaying.
• Automate super payments through your payroll software to avoid missing the quarterly deadline.
