IRD disputes, tax debt & catch-up returns

Behind on returns? Start here

Falling behind on tax is more common than people admit, and it's rarely because someone didn't care. Life gets busy, a business gets hard, one missed return becomes three, and the longer it's left the scarier it feels to open the letter. If that's you, the first thing to know is this: it's fixable, and acting now almost always costs less than waiting.

The worst outcome usually isn't the tax itself. It's the penalties and interest that pile up while returns sit unfiled, and the estimated assessments IRD can issue in the absence of a return, which are frequently higher than your real position. Filing the actual returns often reduces what IRD thinks you owe.

Here's how we approach it calmly:

• Work out exactly which years and which returns are outstanding
• Gather the records, even partial ones, and reconstruct what's missing
• File the real returns so the position is correct, not estimated
• Deal with any resulting debt through the right arrangement

No judgement, just a clear path out. Most people feel markedly better after the first call simply because there's finally a plan.

Filing catch-up returns the right way

Catch-up returns need to be filed in order and accurately, because each year often feeds into the next. Provisional tax, losses carried forward, and prior-year credits all flow between years, so filing them out of sequence or with gaps creates errors that have to be unpicked later.

Our process:

• Reconstruct the records from bank statements, invoices, or whatever you have, even if it's incomplete. We're used to working from messy or partial information.
• File chronologically, so each year's closing position correctly opens the next.
• Apply every legitimate deduction, because catch-up years are often where the most over-assessment hides. Estimated assessments rarely include your expenses; your real return does.
• Replace IRD's estimates with your filed figures, which frequently lowers the balance.

The result is a true, defensible position across all the outstanding years, which is the foundation for sorting out any debt sensibly. See our catch-up tax returns guide for more on how this works.

Understanding IRD penalties and interest

It helps to understand what you're actually being charged, because the components are treated differently and some can be reduced.

The distinction matters because penalties can sometimes be reduced or remitted, especially where you come forward voluntarily, while interest is more mechanical but can be managed through tools like tax pooling. Shortfall penalties in particular drop significantly when a disclosure is made before IRD starts asking.

We work out which charges apply, which can realistically be reduced, and how to frame the case for relief, then put that to IRD on your behalf. Our IRD penalties and interest guide breaks each one down.

Instalment arrangements and write-offs

If the bill is real but you can't pay it in one go, you're not stuck. IRD would generally rather agree a payment plan than chase a debt indefinitely, so a well-structured instalment arrangement is often very achievable.

An instalment arrangement lets you pay the debt down over time in regular amounts you can actually afford. Setting one up before IRD takes recovery action also tends to be looked on more favourably, and entering an arrangement can reduce some ongoing penalties.

• Instalment arrangement: a structured plan to pay over weeks or months
• Penalty remission: a request to reduce or remove certain penalties, often alongside the plan
• Write-off / hardship relief: in genuine financial-hardship cases, IRD can write off some debt that can't be recovered without serious hardship

The key is proposing something realistic and backing it with the numbers. We assess what you can sustainably pay, structure a proposal IRD is likely to accept, and put it forward, then keep it on track. Our how to set up an IRD instalment arrangement guide explains the steps.

Responding to IRD letters and audits

An IRD letter landing in your inbox is stressful, and the instinct is either to panic-reply or to ignore it. Neither helps. Most letters are routine, asking you to file something, confirm a figure, or explain an entry, and a calm, accurate response usually closes them out.

Where it's more serious, such as a review or audit, how you respond genuinely matters. IRD is checking whether your returns are correct, and a measured, well-evidenced reply that addresses exactly what's asked, no more and no less, tends to resolve things faster and on better terms.

• We read the letter properly and work out what's actually being requested
• We respond on time, with the right information and supporting records
• In a review or audit, we manage the correspondence so you're not facing IRD alone or saying more than needed

You don't have to deal with IRD directly if you'd rather not. As your point of contact we handle the letters, so a worrying envelope becomes our job, not your sleepless night.

Voluntary disclosure

If you know there's something wrong, an income source not declared, an error in a past return, or returns that simply weren't filed, the single most powerful step you can take is a voluntary disclosure: telling IRD before they come to you.

Coming forward voluntarily generally means significantly reduced shortfall penalties, and it puts you in control of the conversation rather than on the back foot. A pre-notification disclosure (made before IRD signals an audit) typically attracts a far larger penalty reduction than one made after they've started looking.

• You decide the timing and frame the facts honestly
• Penalties are typically much lower than if IRD finds the issue first
• It often heads off a full audit entirely

The honest message we give clients is simple: if there's something there, voluntary disclosure is almost always the cheaper and calmer road. We help you decide whether it applies, prepare the disclosure properly, and present it in the way most likely to earn the available relief.

Fixed-fee pricing

We price this work as a fixed fee wherever we can, agreed after a free review, so dealing with a stressful situation doesn't come with an open-ended bill on top.

• Catch-up returns, priced per year or as a multi-year package
• Instalment arrangement negotiation with IRD
• Penalty remission and voluntary disclosure work
• Audit and review support, scoped up front

Where a matter is genuinely open-ended, we'll be upfront about that too, and agree clear stages so you're never surprised. The aim is to make getting straight with IRD affordable, not another thing to dread.
