Yes. Affiliate commission is income, and income is taxable essentially everywhere. There is no threshold below which it stops being income, and no version of “it was only a few hundred” that makes it disappear.
What varies is how it is classified, when you must declare it, and what you can deduct.
What kind of income it is
Almost always self-employment or business income rather than casual earnings. You are being paid for an activity you undertook deliberately and repeatedly, which is the usual test.
That classification matters because it generally brings a filing obligation, the ability to deduct costs, and in some countries a separate self-employment charge on top of income tax.
The parts creators get wrong
| Assumption | Reality |
|---|---|
| “Below the threshold, so nothing to do” | Thresholds usually govern whether tax is owed, not whether it must be declared |
| “They did not send me a form” | Reporting thresholds are the payer’s obligation. Yours is unaffected |
| “It is paid abroad so it does not count” | Most countries tax residents on worldwide income |
| “Gifted products are not income” | Products received for coverage are often taxable at market value |
| “I will sort it when it is bigger” | Backdating records is far harder than keeping them |
| “It is a hobby” | Intent to profit generally makes it a business, whatever the amount |
What you can usually deduct
Costs incurred to earn the income. Typically: hosting and domains, editing software, equipment used for the work, a proportion of phone and internet, professional fees, and platform or network charges.
The test is normally whether the cost was genuinely for the business. Mixed-use items — a laptop used for work and everything else — are usually apportioned rather than claimed in full.
Deductions are why declaring properly often costs less than people fear. Tax is on profit, not on the commission figure.
Records worth keeping from day one
Monthly earnings statements from every network. Bank records showing what actually arrived. Receipts for anything you intend to deduct. A note of the exchange rate where you were paid in another currency. A record of gifted products and their value.
A spreadsheet updated monthly is enough at this scale. The work is trivial while it is current and genuinely painful eighteen months later.
Set money aside as it arrives
Affiliate income arrives with nothing withheld. All of it looks like yours, and a portion is not.
Move a share into a separate account as each payment lands. The right percentage depends on your country and total income — ask an accountant for the number once, then apply it mechanically. The people who get into difficulty are not the ones who earned too much; they are the ones who spent the tax.
When to get advice
Once it is regular rather than occasional, if you are paid from another country, if you receive significant gifted product, or if you are considering a company rather than operating personally.
One consultation, early, usually pays for itself in deductions you did not know you could claim. For the disclosure side of compliance, see how to write a disclosure.
