What's an instalment arrangement, and will a lender care?

Of all the tax words that make business owners nervous, “instalment arrangement” is the one Mr would most like to rehabilitate. It isn’t a black mark. Used properly, it’s one of the most sensible things a business behind on tax can do — and lenders generally see it that way.

What exactly is an instalment arrangement?

It’s an agreement with Inland Revenue to pay a tax debt over time in regular amounts, rather than in one lump. It can cover GST, PAYE, income tax and other tax types. IRD describes it as a way to manage your tax when you can’t pay in full by the due date.

The two things that make it useful:

• It calms the chase. While you’re paying as agreed, you’re working with IRD rather than waiting for its next collection step.
• It reduces penalties. IRD says regular agreed payments mean you’ll pay fewer penalties than if you simply left the debt outstanding. Interest can still apply to the balance.

How do I set one up?

Through myIR, in most cases. IRD’s online process asks you:

1. How much you can afford towards the debt.
2. How you’ll pay — direct debit is the common choice.
3. When you want to start.

You can pick weekly, fortnightly or monthly payments, as long as they add up to at least the weekly minimum IRD displays. If you can’t manage that minimum, IRD will take your contact details and call to discuss other options.

For business customers, IRD may ask for a twelve-month cash flow forecast (IR591). Our twelve-month cash flow forecast guide shows how to build one that’s honest and useful — it doubles as excellent lender preparation.

Will a lender care that I’m on one?

Yes, but usually not the way people fear. Here’s how lenders tend to read it:

What the lender sees	How it’s usually read
Arrangement in place, all payments made on time	Positive — debt acknowledged and under control
Arrangement just started	Neutral to positive — plan exists, track record building
Arrangement with missed payments	Concern — cash flow may not support new borrowing
Debt with no arrangement and no contact with IRD	Real concern — enforcement risk

The important thing is honesty. Lenders will ask about tax, and many will see IRD payments in your bank statements. Disclosing the arrangement, with a myIR statement showing it’s on track, is far better than having it discovered.

Should I keep the arrangement or pay it out with a loan?

There’s no single right answer. Consider:

• The size of the debt. Small arrangements are often best left to run.
• The cost comparison. Compare interest and remaining penalties on the IRD debt against the full cost of a loan.
• Your cash flow. Will a loan repayment be easier or harder to carry than the arrangement payment?
• Pressure points. If IRD has made the arrangement conditional, or you’ve already missed payments, clearing it may remove risk.
• What else you need. Sometimes a single loan that clears IRD and funds a business need is cleaner than two obligations.

If you’d like help weighing it up, tell us your numbers and a specialist will talk through both paths with you.

What keeps an arrangement on track?

• Set the payment by direct debit, timed after your usual big deposit days.
• Keep current returns filed on time — falling behind on new obligations can put the arrangement at risk.
• Pay current GST and PAYE in full as they fall due; don’t let a new debt grow beside the old one.
• If a payment is going to be missed, call IRD before the date, not after.

The tax due dates tool lists your GST, PAYE and provisional tax dates for the year so nothing new sneaks up on you.

Does an arrangement show on my credit file?

Not in itself. However, IRD can share information about significant company tax debt with credit reporting agencies in certain circumstances. Being on an arrangement and engaging with IRD is part of staying out of that territory. Read can IRD tell credit bureaus about my tax debt? for the 2026 rules.

An illustrative example: the arrangement that helped a loan

This case is invented to show how it can play out.

A café owner in New Plymouth fell behind on GST after a slow winter and a broken coffee machine landed in the same month. She filed her returns, applied for an instalment arrangement in myIR, and set up a fortnightly direct debit timed for the day after her best trading weekend. Six months later she’d made every payment.

When she needed to borrow to replace a failing commercial fridge, here’s what a lender saw:

• a myIR statement showing the GST balance falling steadily;
• six months of on-time arrangement payments in her bank statements;
• current GST periods paid in full alongside the arrangement;
• a clear, modest purpose for the new loan.

Rather than counting against her, the arrangement showed discipline. The conversation became about whether to leave the arrangement running and borrow just for the fridge, or to clear the remaining GST at the same time with a slightly larger loan. Because the arrangement balance was small and the remaining payments were comfortable, she left it running.

What IRD may ask a business for

If your situation is more complex, or the amount is larger, IRD may want to understand your finances before agreeing to an arrangement. For businesses, that can include a twelve-month cash flow forecast on form IR591. It’s worth knowing:

• the forecast should be realistic, not hopeful — IRD and lenders both see through optimism;
• it should include current tax obligations as well as the arrangement payments;
• it should show your quiet months honestly.

Preparing one carefully pays twice: once with IRD, and again with any lender who asks how the business will manage its commitments.

Talk to someone who’s seen it before

An instalment arrangement is a normal part of business life for plenty of New Zealand owners. If you’re on one, or thinking about one, tell us where things stand. There’s no credit check to ask, your details stay with the person handling your enquiry, and a real specialist will explain whether a loan would help or whether the arrangement is the better path.

Please include your IRD balance and arrangement details accurately on the form — it means our first suggestion will fit. Ask Mr about borrowing while on an arrangement.
