Do you have to pay tax on TradeMe sales in New Zealand? If you are just clearing out your garage and selling personal, second-hand items (like an old sofa or used clothes) for less than you bought them for, you do not have to pay tax to the IRD. However, if you buy, make, or import items specifically with the intention of selling them for a profit, you are legally operating a business and must declare that income.
TradeMe is practically a national institution in New Zealand. Every weekend, thousands of Kiwis log on to declutter their homes and make a little extra cash. But as the cost of living crisis pushes more people to start online side-hustles, the Inland Revenue Department (IRD) is paying much closer attention to digital marketplaces.
The line between a harmless weekend garage sale and a taxable, unregistered business is incredibly thin. Many Kiwis mistakenly believe that if they do not have a registered company, or if they earn less than a certain “hobby” threshold, their online profits are tax-free. This is a dangerous myth that can lead to severe financial penalties and audits.
Before you list your next batch of items or log into your myIR account to check your annual tax position, you must understand exactly how the government views your digital storefront. In this comprehensive guide, we break down the IRD’s “intention test” and explain exactly when your casual TradeMe hobby legally transforms into a taxable business.
The IRD’s “Intention Test”: Are You a Hobbyist or a Business?
The Inland Revenue Department (IRD) does not care if you have officially registered a company on the Companies Office website. They do not care if you consider yourself a “casual seller” or if you only trade on weekends from your smartphone. When deciding if your TradeMe sales are taxable income, the IRD relies almost entirely on the “Intention Test.”
The core of the Intention Test is a single question: When you acquired, made, or imported the item, was your primary intention to sell it and make a profit?
If the answer is yes, you are legally operating a business and every dollar of profit is subject to income tax. If you bought an item for personal use and later decided to sell it, you are generally just a hobbyist or a consumer clearing out space.
Hobby vs. Business: Where Do You Stand?
Because the line between a hobby and a business can sometimes feel blurred, the IRD looks for specific patterns of behavior. Review the table below to see which profile your TradeMe activity actually matches:
| Activity Pattern | Tax-Free Hobby (Personal) | Taxable Business (Commercial) |
|---|---|---|
| Acquisition | You bought the item to use yourself or for your family. | You bought, imported, or made the item specifically to resell. |
| Frequency | Occasional or one-off sales (e.g., an annual garage clear-out). | Regular, ongoing, and systematic listings. |
| Pricing Strategy | Selling for less than the original purchase price (taking a loss). | Pricing items strategically to ensure a clear profit margin. |
| Inventory | Selling items you no longer need. | Holding stock, buying wholesale, or consistently replenishing items. |
The Dangerous Myth of the “Tax-Free Threshold”
One of the most common and dangerous myths floating around New Zealand Facebook groups and online forums is the idea of a “tax-free threshold” for hobbies. You will often hear people say, “As long as I earn less than $500 (or $1,000) a year on TradeMe, I don’t have to declare it to the IRD.”
This is 100% false.
In New Zealand, there is no specific dollar amount that automatically exempts you from paying tax if you are operating a business. If your TradeMe activity meets the IRD’s Intention Test—meaning you bought or made the items specifically to sell them for a profit—then every single dollar of that profit is classified as taxable income. Whether you made $50 or $50,000, you are legally required to include that net profit in your annual IR3 individual income tax return.
⚠️ Warning: The Digital Footprint
Do not assume you can fly under the radar just because your sales are small. The IRD possesses sophisticated data-matching technology and frequently requests bulk user transaction data directly from TradeMe, banks, and payment processors to identify unregistered online businesses.
What About Selling Personal Second-Hand Goods?
If reading the above made you panic about the old sofa you just sold, take a deep breath. The IRD is not coming after your weekend garage clear-out.
When you sell personal household items—such as a used couch, your children’s outgrown clothes, or a mountain bike you no longer ride—you are almost always selling them for less than what you originally paid for them. Because you are taking a financial loss, and because your original intention was to use the item (not resell it), the IRD classifies this as the disposal of private property.
You do not need to declare the money you make from selling your own personal, second-hand goods at a loss. This money is completely tax-free.
When Do You Need to Register for GST?
When researching how much can you earn before paying tax nz, it is absolutely crucial to understand the strict difference between standard income tax and Goods and Services Tax (GST). As we established above, if you are running a TradeMe business, you pay income tax on your net profit from the very first dollar. However, GST operates under a completely different mathematical threshold.
So, do I need to register for GST nz if I am just starting my digital side-hustle? The IRD rule is very clear: You only need to legally register for and charge a 15% GST on your items if your total business turnover (your total sales income, before any expenses are deducted) has exceeded $60,000 in the last 12 months, or if you expect it to exceed $60,000 in the next 12 months. If your online store is small and your turnover is under this $60k limit, you do not need to worry about GST. You simply declare your end-of-year profit for standard individual income tax.
💡 Pro Tip: Lower Your Tax Bill by Claiming Expenses
If the IRD officially considers your TradeMe activity a business, the massive silver lining is that you are legally entitled to start claiming business expenses nz to dramatically reduce your taxable profit. You do not pay tax on your total sales revenue; you only pay tax on the profit left over after deducting your operating costs.
Crucial deductions you must track include:
- TradeMe seller fees tax deductible: Every single listing fee, success fee, and Ping transaction fee is a 100% deductible business expense.
- Shipping and Packaging: The exact cost of courier bags, bubble wrap, printer ink, and postage.
- Home office expenses IRD: If you use a spare room or a section of your garage specifically to store your inventory or pack orders, you can claim a percentage of your household rent, mortgage interest, power, and internet bills based on the square meterage of that dedicated workspace.

Final Verdict: Keep Meticulous Records
If your TradeMe activity passes the IRD’s Intention Test and is legally classified as a business, the most important habit you can build right now is meticulous record-keeping. You do not need to panic or immediately hire an expensive accountant, but you do need to start tracking every dollar.
Your Action Plan for 2026: Open a simple Excel spreadsheet or Google Sheet today. In one column, record every single dollar you receive from TradeMe buyers (including the shipping fees they pay you). In the second column, record every single deductible business expense (listing fees, courier costs, wholesale inventory purchases). At the end of the New Zealand financial year (March 31), you will simply subtract your total expenses from your total income. That final net profit number is what you will declare to the government on your individual IR3 tax return.
Frequently Asked Questions About TradeMe and IRD Rules
Do I need to register a formal company to sell on TradeMe?
No. You do not need to register a formal Limited Liability Company on the Companies Office website to operate a taxable business on TradeMe. You can legally operate as a “Sole Trader” using your own personal IRD number. You simply declare your TradeMe profits alongside your regular salary on an IR3 individual tax return.
Can the IRD actually see my TradeMe sales history?
Yes. The Inland Revenue Department has massive data-matching capabilities and significant legal powers. They frequently request bulk user data directly from TradeMe, New Zealand banks, and online payment gateways to cross-reference transaction histories and catch unregistered online businesses avoiding income tax.
How do I actually pay the tax I owe from my TradeMe sales?
If you are operating as a sole trader, you must file an IR3 individual tax return at the end of the financial year (between April 1 and July 7). You will input your total net profit from TradeMe into the “Self-employed income” section. The myIR portal will then automatically calculate exactly how much tax you owe based on your overall annual income bracket.
