How tax works for online business nz can feel like a total mission when you’re just starting out. Good on you for getting your Shopify store or side-hustle up and running, that’s the exciting part. The less exciting part is figuring out what on earth you owe the IRD. Let’s be honest, when I first started, my own record-keeping was a bit of a dog’s breakfast, and I definitely missed a few things I could have claimed.
This guide is here to make sure you don’t make the same mistakes. We’re going to cut through all the jargon and give you a straight-up New Zealand business tax guide. We’ll cover the essential NZ online business tax requirements, break down the rules for GST for ecommerce NZ, and show you the basics of claiming business expenses online NZ. My goal is to make understanding how tax works for your online business in NZ a bit less of a headache, so you can get back to the good stuff.
Is your online activity a business or a hobby?
Before we dive into the nitty-gritty of tax rates, you need to figure out if what you’re doing is actually a business in the eyes of the IRD. It’s a bit of a grey area, but the IRD has some clear pointers. A hobby is something you do for fun; a business is something you do with the intention of making a profit.
According to the IRD, you’re likely running a business if you:
- Buy or create items specifically to resell them.
- Sell your goods or services regularly.
- Have a business plan and keep records.
- Have a separate bank account for your sales.
If you just sell your old junk on TradeMe once a year, that’s probably not a business. But if you’re buying vintage clothes every weekend to flip online for a profit, you’re almost certainly running a business and need to declare that income.
Tax types you need to know
Once you’ve confirmed you’re running a business, you’ll need to get your head around a few different types of tax. It’s not as scary as it sounds, and getting the basics right from the start will save you a world of pain later on.
Income tax
This is the main one. Income tax is paid on your net profit, which is your total income minus all your legitimate business expenses. The way you pay it depends on your business structure.
• Sole Trader: This is the simplest setup and, according to Stats NZ, sole traders make up a massive chunk of New Zealand’s businesses. You and the business are one and the same for tax purposes. The profit your business makes is your personal income, and you pay tax at your personal marginal tax rate.
• Company: A company is a separate legal entity. It pays tax on its own profits at a flat rate of 28%. If you then pay yourself a salary from the company, you’ll pay income tax on that salary personally. Here’s a look at the personal income tax rates from 1 April 2025, as per the latest IRD update.
| Taxable Income | Tax Rate |
|---|---|
| $0 – $15,600 | 10.5% |
| $15,601 – $53,500 | 17.5% |
| $53,501 – $78,100 | 30% |
| $78,101 – $180,000 | 33% |
| Over $180,001 | 39% |
Let’s make that a bit more real. Say your online store has a cracking year and you make a net profit of $60,000 as a sole trader. You don’t just pay a flat 30% on the whole lot. You pay: • 10.5% on the first $15,600 = $1,638 • 17.5% on the next chunk (from $15,601 to $53,500) = $6,632.50 • 30% on the final bit (from $53,501 to $60,000) = $1,950 Your total income tax bill for the year would be $10,220.50. See? It’s not as bad as you might think once you break it down.
GST (Goods & Services Tax)
GST is a 15% tax on most goods and services in New Zealand. You don’t have to worry about it until your business turnover hits a certain point.
The magic number is $60,000. If your turnover (total sales, not profit) was more than $60,000 in the last 12 months, or you think it will be in the next 12 months, you must register for GST. Once registered, you have to charge 15% GST on all your sales in NZ and file regular GST returns with the IRD. The upside is you can also claim back the GST you pay on your business expenses. Understanding GST for your online business in NZ is crucial for pricing and compliance.
ACC levies
If you’re self-employed as a sole trader, you’ll also need to pay ACC levies. These cover you if you have an accident and can’t work. After you file your first tax return, ACC will send you an invoice based on your reported income. It’s a cost of doing business, so make sure you budget for it. You can find out more about how it works on the Business.govt.nz website.
Specific tax rules for online businesses
Running an online business means you can have customers anywhere, from down the road to halfway across the world. This adds a few extra layers to your online business tax NZ obligations.
Selling goods online (NZ & overseas)
For sales to Kiwi customers, the rules are simple: you declare the income, and if you’re GST-registered, you charge 15% GST. For overseas customers, it’s a bit different. Sales of goods exported to customers outside New Zealand are generally ‘zero-rated’ for GST. This means you charge them 0% GST, but you can still claim back the GST on the expenses related to making that sale.
Digital products & remote services
The rules for digital products (like e-books or software) and remote services (like consulting or design work) can get tricky. If you’re selling these to Kiwi customers from within NZ, you treat them like any other sale. However, if you are a non-resident business selling digital services to NZ consumers, you may have to register for and charge GST, even if your turnover is below $60,000. The IRD provides specific guidance on these remote services rules.
Selling on marketplaces like TradeMe or Etsy
It doesn’t matter where you sell your products; income is income. Whether you’re making sales through your own Shopify site, TradeMe, Etsy, or a Facebook group, the IRD sees it all as business income. Platforms like these won’t handle your IRD online trading tax for you, so it’s your job to track every dollar you earn and declare it.

Claims, expenses & record-keeping
This is where you can save some serious money. Any expense that’s directly related to running your online business can usually be claimed to reduce your taxable profit. The golden rule is: if you spent money to make money, you can probably claim it.
Common expenses for an online business include:
- Cost of goods sold: The actual cost of the products you sell.
- Platform fees: Shopify, Etsy, or marketplace fees.
- Marketing costs: Google Ads, social media advertising, etc.
- Software and subscriptions: Accounting software, email marketing tools, design apps.
- Website costs: Domain names and web hosting.
- Shipping and packaging supplies.
- Home office expenses: You can claim a portion of your rent, power, and internet. The IRD has a guide on how to calculate this.
The key to claiming expenses for your online business in NZ is keeping flawless records. You must keep all invoices and receipts for at least seven years. Using accounting software can make this a whole lot easier and help you boost your business efficiency with smart digital tools.
A step-by-step checklist for getting started
Feeling a bit overwhelmed? No worries. Here’s a simple checklist to get you on the right track from day one.
- Decide if you’re a hobby or a business. Be honest with yourself about your intentions.
- Choose your business structure. For most people starting out, being a sole trader is the easiest path.
- Get an IRD number. If you don’t already have a personal one, you’ll need it.
- Open a separate bank account. This is not a legal requirement for sole traders, but trust me, it will make your life a million times easier.
- Set up a record-keeping system. This could be a simple spreadsheet or accounting software like Xero or MYOB.
- Monitor your turnover for GST. Keep an eye on that $60,000 threshold.
- Put money aside for tax. A good rule of thumb is to squirrel away about 20-30% of every payment you receive into a separate savings account.

Common pitfalls & how to avoid them
I’ve seen plenty of people make simple mistakes that end up costing them time and money. Here are the big ones to watch out for.
- Thinking it’s “just a side-hustle”: The IRD doesn’t care if it’s your main gig or something you do on weekends. If you’re making a profit, you need to declare it.
- Forgetting about GST: Hitting the $60,000 turnover mark and failing to register for GST is a classic mistake. The penalties can be nasty.
- Mixing business and personal finances: Using your business account for personal groceries is a recipe for a bookkeeping nightmare. Keep it separate.
- Losing receipts: No receipt, no claim. It’s that simple. Keep digital copies of everything.
When to call in a professional
You can definitely manage your taxes yourself when you’re starting out. But as your business grows, or if things get complicated, getting professional help is a smart move. An accountant can not only ensure you’re compliant but also help you structure your business in the most tax-efficient way.
Consider getting help if:
- Your turnover is approaching the GST threshold.
- You start hiring employees.
- You have significant sales to overseas customers.
- You simply hate doing admin and want to focus on growing your business.

FAQ about tax for online businesses in NZ
Do I have to pay tax on dropshipping in NZ?
Yes, absolutely. The profit you make from dropshipping (the difference between what the customer pays you and what you pay the supplier) is considered taxable income in New Zealand and must be declared to the IRD.
What happens if I don’t declare my online income to the IRD?
The IRD has sophisticated systems for tracking online sales and payments. If you’re caught not declaring income, you’ll face penalties, interest on the unpaid tax, and potentially a full audit. It’s just not worth the risk.
How much can I earn from a hobby before it’s a business?
There is no specific dollar amount. The distinction between a hobby and a business is based on your intention and activity, not your income. If your primary intention is to make a profit, the IRD will likely view it as a business, even if you only make a few hundred dollars.
