GST for freelance writers
in New Zealand — what you need
to know in 2026

GST is one of those things that sits in the background of a freelance writing career, easy to ignore right up until the moment you can't ignore it any more. Then it becomes urgent, slightly alarming, and something you wish someone had explained to you clearly three years ago.

This is that explanation. It's written for writers in New Zealand — not accountants, not IRD bureaucrats, not people who already know what a zero-rated supply is. If you write for a living and you've been quietly hoping GST will sort itself out, this is the article you need to read today.

First — why is everyone talking about GST right now?

April 2026 brought a change that's relevant to any NZ writer who uses international freelance platforms. Upwork — one of the largest global freelancing marketplaces — began collecting GST from New Zealand users this month. That means if you use Upwork to find clients or work, GST is now being applied to the platform fees you pay. And if you have a GST number, you need to make sure it's registered with Upwork so you're not being double-charged.

It's also a useful reminder that GST doesn't only apply to the money you earn. It applies to the platforms and services you pay for in your writing business too — and understanding how it works on both sides of the equation is increasingly important.

The $60,000 threshold — what it means and when it applies

In New Zealand, you are required to register for GST if your annual turnover exceeds — or is expected to exceed — $60,000 in any 12-month period. Not the financial year. Any rolling 12-month period. That distinction catches a lot of people out.

So if you had a particularly good six months — a book advance, a corporate content project, several commissions stacking up — and your income for the previous 12 months crossed $60,000, you need to register for GST. The obligation doesn't wait for the new tax year.

Once you hit that threshold, you have 21 days to register. You can do it yourself through myIR at ird.govt.nz. It takes about 20 minutes and is genuinely straightforward.

Should you register voluntarily if you're below $60,000?

This is a question worth thinking about, because the answer isn't always no.

If you have meaningful business expenses — a laptop, software subscriptions, a home office, professional development costs — you can claim the GST back on those purchases once you're registered. If your expenses are significant relative to your income, voluntary registration can actually put money back in your pocket through GST refunds on your inputs.

The downside is that you then have to add GST to your invoices — which effectively increases your prices by 15% for clients who can't claim it back (mainly individuals and non-registered businesses). For most magazine editors and publishing house clients, this isn't an issue — they're GST-registered and can claim your GST as an input. But for private clients, tutoring, or individual readers buying your self-published work directly, adding GST changes the maths.

My honest advice: if you're approaching $60,000 or regularly have significant business expenses, talk to an accountant before you register voluntarily. The decision has implications that go beyond the simple question of whether you have to.

What changes when you register

Once you're GST-registered, three things change immediately.

You start adding GST to your NZ client invoices. For a $1,000 article fee, you now invoice $1,150 — the $150 is GST, which you collect on the IRD's behalf and pass on when you file your return. The $1,000 is your income. The $150 is never really yours, even though it sits in your account between invoices.

You start claiming GST back on business expenses. That $115 software subscription? The GST component ($15) is claimable. Your professional memberships, your laptop, your home office costs — all of them have a GST component you can recover. This adds up meaningfully over a year.

You start filing GST returns. For most freelance writers, this will be two-monthly — you file a return every two months reporting what GST you collected and what you're claiming back, and either pay the difference or receive a refund. Six-monthly filing is available if your turnover is lower.

This last point is the one that trips people up most often. It's easy to look at your bank balance — which includes all the GST your clients have paid you — and feel more prosperous than you actually are. The discipline of setting aside the GST component as soon as it arrives is one of the most important financial habits a GST-registered writer can build. Open a separate account, or at minimum track it carefully. That money belongs to the IRD.

Overseas clients and zero-rating — the rule that actually helps you

Here's something many writers don't know: if you're GST-registered and writing for overseas clients — an Australian publication, a UK magazine, a US content platform — you generally don't charge GST on those invoices. They're zero-rated, meaning GST applies at 0%.

This is genuinely good news, and not just because it keeps your prices competitive internationally. It means you can still claim GST back on all your NZ business expenses — software, professional memberships, equipment — even though you're not charging GST to your overseas clients. Writers who do significant work for international clients often find themselves in a net GST refund position: they claim more back than they collect. The IRD sends you a refund. That's not a loophole — it's how the system is designed to work for export services.

For cross-Tasman work specifically: Australian clients are overseas clients for GST purposes. You don't charge NZ GST to an Australian magazine or publisher. You invoice in whatever currency you've agreed (NZD or AUD), and the zero-rating applies.

What must appear on a tax invoice

This is where writers most commonly make mistakes — not because the rules are complicated, but because nobody ever told them what a proper NZ tax invoice looks like.

If you are GST-registered and issuing invoices over $50, every invoice must include:

• The words "Tax Invoice" — prominently, at the top
• Your name or business name
• Your GST number (not your IRD number — they're different)
• The date of the invoice
• A description of the goods or services provided
• The amount charged, showing the GST component separately
• The total including GST

If you are not GST-registered, you can still issue invoices — but they should not say "Tax Invoice" and must not include a GST line. A non-registered writer charging a client $1,000 issues a plain invoice for $1,000. That's it. No GST number, no GST line.

The mistake to avoid: adding a GST line to your invoice when you're not registered. Some clients will flag this. Others will pay without noticing — but you've then collected GST you have no right to collect and no mechanism to remit. It's a problem you don't want.

Filing frequency and the payments basis

When you register, you'll choose a filing frequency and an accounting basis. For most freelance writers, the right choices are:

Filing frequency: two-monthly. This is the most common for small freelance businesses. You file every two months and payment (or refund) is due by the 28th of the following month.

Accounting basis: payments. On the payments basis, you account for GST when money actually changes hands — when a client pays your invoice, not when you issue it. This is simpler for most writers and means you never end up paying GST to the IRD before you've actually received it from the client.

The alternative — invoice basis — means you owe GST as soon as you issue the invoice, whether or not the client has paid. For writers who sometimes chase late payments, this can create cash flow problems. The payments basis avoids that.

ACC — the bill that arrives after your first tax return

This isn't strictly a GST topic, but it comes up alongside GST for new freelancers and it's worth knowing about. When you file your first IR3 tax return, the IRD shares your earnings with ACC. Within a few months, you'll receive an ACC levy invoice — a levy on your earnings that covers your accident insurance as a self-employed person.

It arrives unannounced and can feel like a surprise if nobody warned you. The amount depends on your earnings and your occupation code. For writers, it's generally modest — but budget for it, because it comes on top of your income tax and isn't something you can avoid.
