How long can an ATO payment plan be?

The two year online limit

The ATO's self-serve channels (online services for individuals, online services for business, the self-help phone line, and online services for agents) will accept a plan of up to 2 years without anyone reviewing it, provided the debt is $200,000 or less and you are otherwise eligible. Approval is usually immediate.

The same limit applies later. You cannot change a plan online if it already runs longer than 24 months, or if the change you want would push it past 24 months. Anything beyond that needs a phone call.

Two things take you out of the online channel regardless of term:

• you have defaulted on or cancelled two or more payment plans in the past 12 months
• you have received a warning of firmer recovery or legal action in the past 6 months

Plans longer than two years

Longer plans exist, but they are negotiated rather than granted. When you phone the ATO's debt line, expect to be asked what caused the debt, what has changed, and what you can pay each month after covering your ongoing tax. For larger debts the ATO may ask for bank statements, a cash flow forecast, or an upfront payment before agreeing. Debts over $200,000 always go through this route; see payment plans over $200,000.

The ATO can also refuse a long term it does not think is realistic. If you are told no, payment plan rejected explains the next moves.

Why shorter is usually better for you

Interest does not pause during a plan. GIC at 11.43% compounds daily on the unpaid balance and, since July 2025, is not deductible. A $50,000 debt costs roughly twice as much interest over 24 months as over 12. There is a real trade off: a term that is too short fails, and a failed plan puts you in a worse spot than no plan. A term that is too long quietly costs thousands.

A practical approach:

1. Work out what you can pay each month after rent, wages, suppliers and the next BAS. Be honest, not optimistic.
2. Divide the debt (plus a rough allowance for interest) by that monthly figure to get the term.
3. If it lands under 24 months, set it up online. If not, prepare your evidence and call.
4. If it lands well past 3 years, the plan may not be the right tool. Read rescue options before committing.

What to do next

1. Write down what you can pay each month after your normal bills and the next BAS or instalment.
2. Divide your total debt by that amount to see whether the plan fits inside 24 months.
3. If it fits, set it up in ATO online services. If not, gather bank statements and a simple cash flow summary before calling the ATO.
4. If the term would run past three years, get advice on whether a plan is the right option at all.
