Budget 2026: the bits that actually matter for your business

Every year the Budget lands with a flurry of headlines, and every year most business owners skim the top line and move on. Fair enough. When the news leads with "no tax cuts," it is easy to assume there is nothing in there for you.

But that would be a mistake this time.

Budget 2026, delivered by Finance Minister Nicola Willis on 28 May, left company tax, income tax and GST rates exactly where they were. No change. What it did do, quietly, was deliver one of the more substantial sets of smaller tax changes we have seen in a while. Several of them will land directly on the desks of Kiwi business owners, and one of them is retrospective, which means the clock may already be running.

Here is what is worth knowing, and more importantly, what it means for you.

One thing to keep in mind as you read on. Most of these are proposals announced in the Budget, not law yet. They still need to pass through Parliament, and the finer detail can change along the way. So treat the dates and rates below as the current plan rather than the final word, and as a prompt to start thinking ahead rather than to act in a panic.

First, the big picture

The Government framed this as a "responsible Budget to secure New Zealand's future." Translation: a focus on getting the books back to surplus, paying down debt, and pouring money into infrastructure like hospitals, schools and roads.

The forecasts are cautiously upbeat. The economy is tipped to grow by an average of 2.7 percent over the next four years, unemployment is expected to fall from 5.5 percent to 4.3 percent, and the country is now forecast to return to surplus in 2028/29, a year earlier than previously thought.

That matters to you in a roundabout way. A return to surplus and falling debt tend to take pressure off interest rates over time, and the heavy infrastructure spend means more work flowing to the construction, trades and engineering sectors. If that is your world, keep an eye on the pipeline.

Now to the changes that hit closer to home.

Fringe benefit tax on vehicles is getting an overhaul

If your business owns vehicles, this one is for you.

From a proposed start date of 1 April 2027, the work-related vehicle exemption that many businesses lean on would be scrapped and replaced with a category-based system. Rather than the type of vehicle driving the treatment, the rate would depend on how much the vehicle is used privately, with different rates signalled for electric, hybrid and standard vehicles. The standard cost rate is also proposed to rise, from 20 percent to 22.8 percent of the vehicle's cost.

The Government is calling this a simplification, and on the logbook side it should be. The fiddly requirement to track every trip in detail would be replaced with a "close enough is good enough" approach.

But here is the catch. Every vehicle in your fleet would need to be reassessed and slotted into one of the new categories, including the ones that were previously exempt. Some of those exempt vehicles may end up attracting an FBT bill where they did not before. If you have an employee with full private use of a company vehicle, your cost is likely to rise.

This is still a proposal, and the detailed rules have not even been released yet, so the specifics may move before it becomes law. You have time either way. The smart move is to keep an eye on the detail as it firms up and map your fleet against the new approach well ahead of any 2027 start, so there are no surprises.

Shareholder loans and dormant companies: the urgent one

This is the change to read twice.

If you have ever drawn money out of a company as a shareholder loan, and that company is later removed from the Companies Register, the proposed rule would treat the outstanding loan as income six months after removal. That triggers a tax liability.

Why does this matter so much? Because the proposal is to apply it retrospectively to companies removed from the Register on or after 4 December 2025. That date is already behind us. So even though this is still to be legislated, the proposed start point means a dormant company that has quietly lapsed off the register, without being formally wound up and the shareholder loan cleared, could be caught.

Most business owners who close a company properly, by formally winding it up and squaring away the loan balance, will not be affected. The risk sits with the ones that were left to fall off the register without anyone dealing with the numbers first.

If you have any dormant or recently deregistered companies in your name, this is worth a conversation with us sooner rather than later.

R&D tax credits: a real cashflow win, with one trade-off

Here is some good news for anyone investing in research and development.

The R&D Tax Incentive is proposed to move to in-year payments. Instead of waiting until the end of the tax year to receive the credit, businesses would get it sooner. That is a meaningful cashflow improvement, because it stops your own innovation from being held hostage by the tax calendar. Inland Revenue would also gain discretion to accept late filings and fix errors, which takes some of the stress out of tight deadlines.

The trade-off sits with internal software. The cap on claimable non-administrative internal software development is proposed to drop sharply, from $25 million to $3 million. For most small businesses this is irrelevant, but if you run significant in-house software development, it is worth checking your claims against the new threshold before year end.

Inland Revenue is being handed more money to chase debt

Budget 2026 puts an extra $15 million a year into Inland Revenue's debt compliance activities, and the Government expects a three-to-one return on it.

Read that as a clear signal. If you have outstanding tax obligations, IRD now has more capacity to come looking. The window to sort things out on your own terms, with a payment arrangement that works for your cashflow, is narrowing. It is far better to get on the front foot than to wait for the letter.

A few others worth a quick mention

The withholding tax exemption threshold for non-resident contractors is proposed to rise from $15,000 to $75,000, which would simplify life for businesses that engage overseas contractors. Families with children could see the in-work tax credit lift by $50 a week, so it is worth checking your own entitlement and flagging it to your team. And for anyone investing offshore, the FIF de minimis threshold is set to double from $50,000 to $100,000.

So what should you actually do?

The honest takeaway is this. Budget 2026 will not transform your tax bill, but it is far from a do-nothing Budget. There are proposed changes to keep an eye on, a proposed retrospective rule worth checking now, and a clear message that Inland Revenue is tightening up.

The business owners who come out ahead are the ones who review their position now, rather than waiting to be prompted. That means knowing where your cashflow sits, having your tax obligations under control, and making sure your business structure still fits the way you operate today.

If any of this has you wondering how it applies to your business, that is exactly the kind of thing we are here for.
