Sole-trader & individual tax returns (IR3)

Who files an IR3

The IR3 is New Zealand's individual income tax return. You need to file one if you earn income that IRD hasn't already taxed in full at source. In practice that covers a lot of people: sole traders and freelancers, contractors on schedular payments, anyone with rental income, people earning overseas income, and those with shareholder salaries or untaxed investment income.

If your only income is salary or wages with PAYE deducted, IRD usually squares you up automatically and you may not need an IR3 at all. The moment you start invoicing clients, take on contract work, or pick up a rental, that changes. You become responsible for declaring the income yourself and paying the tax on it.

Here's the part that surprises new sole traders most: no tax comes out of the money you invoice. A client pays your invoice in full, and the income tax on that money is yours to set aside and pay later through your IR3 and provisional tax. If you don't plan for it, the first bill can be a shock.

• Sole traders and freelancers trading under their own IRD number
• Contractors receiving schedular payments (where some tax is withheld, but rarely enough)
• Rental property owners declaring rent and claiming costs
• People with untaxed income such as overseas earnings, certain investments, or estate income

If you're not sure whether you need to file, that's exactly the kind of thing we sort out on a free review.

What we do for you

We take the IR3 end to end so you don't have to wrestle with myIR or guess at what's deductible. The job is the same whether you're a first-year freelancer or a contractor with a few years of records to tidy.

• Pull your income together from invoices, bank records, or your Xero file, and reconcile it so nothing is missed or double-counted.
• Identify every legitimate expense you can claim, including the ones people routinely forget such as ACC levies, home-office costs, and software subscriptions.
• Calculate your tax position for the year, including any provisional tax already paid, so you know exactly where you stand.
• File the IR3 with IRD on time and confirm it's been accepted.
• Explain the result in plain English, including what to pay, when, and how next year's provisional tax will work.

Because we work with clients across New Zealand remotely, you don't need to come into an office. Share your records (a Xero invite or a folder of statements works fine) and we take it from there. You get a clear summary, not a stack of jargon.

Claiming legitimate business expenses

The rule in New Zealand is straightforward in principle: you can deduct expenses incurred in earning your business income. The art is applying it honestly, claiming everything you're entitled to without straying into things that won't hold up if IRD asks.

Common deductions for sole traders and freelancers include:

• Tools, equipment, and materials used in the work
• Software and subscriptions (accounting, design, hosting, professional tools)
• ACC levies, which are deductible and often overlooked
• Professional fees, insurance, and bank charges on a business account
• A fair share of home-office and vehicle costs where you use them for work
• Phone and internet, apportioned to business use

Where an item is used both privately and for business, you claim only the business proportion. A laptop used 70% for work is claimed at 70%. Keeping that apportionment reasonable and documented is what keeps your return clean. We'll tell you plainly which of your costs qualify, which need apportioning, and which to leave out, so you claim with confidence rather than crossing your fingers.

Use-of-home and vehicle claims

Two of the most valuable, and most fiddled, claims for sole traders are home office and vehicle use. Done properly they put real money back in your pocket. Done loosely they're the kind of thing that invites questions.

Use of home. If you run your business from home, you can claim a portion of household costs such as power, rates, insurance, mortgage interest or rent, and repairs. There are two main approaches:

Vehicle. If you use a vehicle for both business and private travel, you can claim either by keeping a logbook (recording business versus private kilometres) or, within limits, using the kilometre-rate method. A logbook kept for a representative period sets your business-use percentage for a few years.

We work out which method gives you the better, defensible result and set up records that are simple to maintain. See our deeper guides on use-of-home expenses and vehicle and mileage claims for worked detail.

How provisional tax fits in

This is the piece that catches almost every new sole trader. Your first IR3 might show a tax bill of, say, a few thousand dollars. If that residual tax is more than $5,000, you don't just pay it once. IRD then expects you to pay provisional tax towards the following year in instalments, on the basis that your income will likely repeat.

The sting is that in your first profitable year you can end up paying the tax on year one and the first provisional instalments toward year two at around the same time. People call it the "double whammy", and it's the single biggest cash-flow surprise we help clients plan around.

The good news: it's predictable. Once we've prepared your IR3 we can tell you what's owing now, what provisional instalments are coming, and roughly when. From there it's just a matter of setting money aside as you invoice (a rough rule many sole traders use is to park a sensible slice of each payment in a separate account). Our provisional tax explained guide walks through the methods and dates in full.

IR3 deadlines and how we keep you on time

For most people the IR3 covers the tax year ending 31 March and is due by 7 July that year. But there's a meaningful advantage to being linked to a tax agent: clients of a registered tax agent generally receive an extension of time, with returns spread out and many not due until the following 31 March.

That extension does two useful things. It buys you breathing room to get records right rather than rushing, and it shifts some of the cash-flow pressure. Missing the deadline, on the other hand, can trigger late-filing penalties and, if tax is unpaid, late-payment penalties plus use-of-money interest.

How we keep you on track:

• We diarise your return well ahead of its due date and prompt you for records in good time.
• If you're behind on prior years, we file catch-up returns in order so the position is correct before anything else.
• We confirm filing with IRD and tell you exactly what to pay and when, with no vague "sometime soon".

This is general information, not personalised advice. Your due dates depend on your balance date and agent linkage. Confirm your situation with us or check ird.govt.nz.

Fixed-fee pricing

We quote a fixed fee before any work starts, so you know the cost up front. No hourly meter, no surprise invoice at the end. After a short free review we look at the actual shape of your situation, the number of income sources, whether you're GST-registered, how tidy your records are, and quote accordingly.

A clean single-income freelancer return is straightforward and priced as such. A contractor with a rental, some asset purchases, and a couple of years to tidy is more work, and we say so up front rather than discovering it halfway through. What stays constant is that you agree the fee before we begin.

• One-off IR3 for sole traders and freelancers, fixed fee
• IR3 plus GST handling if you're registered
• Catch-up packages where several years need filing

If a simpler option fits you better, we'll say so. The goal is the right amount of help, transparently priced.

Book a free review

The easiest first step is a free 20-minute tax review. We'll ask a few questions about your income, whether you're registered for GST, and anything from IRD that's worrying you, then tell you plainly what your IR3 involves and what it will cost. No obligation, no sales pitch.

Bring a rough idea of your income and expenses and any IRD letters you don't understand. You'll leave the call knowing where you stand and what the next step is.
