Quick answer
If you don't keep to an IRD instalment arrangement, IRD can cancel it. When an arrangement is cancelled for default, IRD's practice statement says monthly incremental penalties can be imposed retrospectively, as if the arrangement had never existed, and a broken arrangement can count against future relief. Contacting IRD before or straight after a missed payment, and either renegotiating or clearing the debt, gives the best chance of limiting the damage.
Key points
- IRD can cancel an arrangement for non-compliance, including missed payments or unpaid new tax.
- If cancelled for default, penalties that were paused can be charged back as if there was no arrangement.
- A broken arrangement can count against you if you ask for relief later.
- Talk to IRD before the missed payment if you can; act within days if you can't.

Instalment arrangements look manageable on the day they’re agreed. Then a customer pays late, a vehicle needs repairs, or the next GST return is bigger than expected, and a payment gets missed. It’s one of the most common points at which IRD debt turns from a manageable problem into a serious one.
What happens when you miss an instalment?
IRD can cancel an arrangement if you don’t keep to it. Its practice statement on relief explains what follows a cancellation for default: monthly incremental penalties “will be imposed retrospectively as if the instalment arrangement had not been entered into” (SPS 18/04).
In plain terms, the protection the arrangement gave you can be unwound. Penalties that were paused may come back, and the debt can look worse than when you started. Exactly what’s added depends on the tax type, because IRD’s penalty rules differ between taxes. For example, the monthly 1% penalty doesn’t apply to GST or income tax, but employer deductions carry their own monthly penalty (IRD). Ask IRD for a revised statement so you can see the actual figures.
Use-of-money interest, which kept running during the arrangement anyway, continues.
Is a missed payment the only way an arrangement breaks?
No. The other common cause is new tax. IRD expects you to stay current with GST, PAYE and income tax as they fall due while the arrangement runs. A business that keeps paying its instalments but falls behind on the next GST return can still find its arrangement in trouble.
Does a broken arrangement affect future help?
It can. SPS 18/04 notes that a broken arrangement can count against you if you later apply for relief. Practically, IRD is also likely to want more evidence before agreeing another plan: a forecast, a lump sum, a shorter term, or proof of what’s changed. See payment plan declined for how to build a stronger proposal.

What should you do if you know a payment will be missed?
Call IRD before the due date. That’s the single most useful thing you can do. A conversation before a default is very different from one after it. Explain what’s happened, how much you can pay now, and when you’ll be back on track. Ask whether the arrangement can be varied. Get the outcome in writing or confirmed in myIR.
What if it’s already broken?
Act within days, not weeks:
- Check myIR for the arrangement status and the current balance.
- Contact IRD to find out whether it can be reinstated or renegotiated, and what it needs.
- Bring new tax up to date if you’ve fallen behind.
- Look at your options honestly. If the arrangement broke because the payments were too high for your cash flow, a new arrangement on the same terms will break again.
What are your options for a reset?
| Option | When it fits |
|---|---|
| Renegotiate with IRD | A one-off shock, now passed, with evidence of recovery |
| Lump sum plus a shorter plan | You can raise some cash, from savings, a sale or a loan |
| Loan to pay in full | The business is viable but cash flow can’t carry IRD instalments plus new tax |
| Accountant review | The arrangement broke because the business isn’t covering its costs |
A loan replaces a plan that IRD can cancel with a fixed facility that has a known cost and term. Property-secured loans run from $20,000 to $5,000,000; cash-flow options are typically $5,000 to $500,000. Compare the dollars with our arrangement vs loan cost check.
How do you stop it happening again?
- Set instalments for your worst month, not an average one.
- Time payments for when money arrives, for example the day after your biggest customer pays.
- Ring-fence new tax in a separate account every week.
- Keep a small buffer so one late customer doesn’t cause a default.
- Diarise every instalment alongside GST and PAYE dates. Our due-date timeline can help.
An illustrative example
Illustrative only. Not a real client and not an offer.
A Gisborne fishing supply business had a 12-month arrangement for about $40,000 of GST. A cyclone-season slowdown caused two missed instalments, IRD cancelled the arrangement and penalties were reassessed. The owners asked IRD for the revised figure, then used a cash-flow loan sized on their recovering takings to clear it. Repayments are lower than the old instalments because the loan term is longer, and IRD’s file is closed.
Who should you tell inside the business?
If you’re a company, every director should know when an arrangement breaks. Directors share responsibility for the company’s tax obligations, and a broken plan often comes before stronger collection steps, such as a deduction notice or, for larger debts, credit reporting. Tell your accountant too. They can check the reassessed figures and help you prepare a proposal or a forecast quickly.
Get back on solid ground
If your IRD arrangement has broken, or you can see it’s about to, start a quick enquiry. Asking doesn’t involve a credit check, your information isn’t forwarded around lenders, and a real person who understands IRD arrangements will call you. Please tell us what’s owing and what went wrong as accurately as you can, so we can tell you whether funding gives you a firmer footing than another plan.
Frequently asked questions
What happens if I miss a payment under my instalment arrangement?
IRD can cancel the arrangement. If it does so because of default, penalties can be imposed retrospectively as if the arrangement had never been entered into. Contact IRD straight away.
Can I get a new arrangement after breaking one?
Possibly, but IRD is likely to want stronger evidence the new plan will hold, and a previous default can count against relief. A lump sum, a shorter term or a loan can help.
Does not paying new GST break my arrangement?
It can. IRD expects you to stay current with new tax while an arrangement runs. Falling behind on new returns is a common reason arrangements fail.
Can a loan fix a broken arrangement?
A loan can pay the outstanding balance in full, which removes the arrangement problem altogether. It works best for viable businesses with property or steady turnover.
