Ecommerce Bookkeeping services vs. Traditional Bookkeeping: What’s the Difference?
April 10, 2025If you’re earning income through the Amazon Affiliate program in the UK, it’s crucial to understand your tax obligations to remain compliant with HM Revenue & Customs (HMRC). This article will explore whether you need to report your Amazon affiliate earnings, how to do so, and recent changes affecting online income reporting.
Understanding Amazon Affiliate Earnings and Tax Obligations
Amazon affiliate earnings are considered self-employed income by HMRC. This means that if you’re generating income through affiliate marketing, you’re responsible for reporting this income and paying any applicable taxes.
The Trading Allowance
In the UK, there’s a Trading Allowance that allows individuals to earn up to £1,000 of gross income from self-employment or casual services without needing to inform HMRC or pay tax on it. If your total income from all self-employed activities, including Amazon affiliate earnings, is £1,000 or less within a tax year, you don’t need to report this income. However, if your earnings exceed this threshold, you must register for Self Assessment and declare your income.
Personal Allowance and Tax Rates
Beyond the Trading Allowance, every individual has a Personal Allowance, which is the amount of income you can earn each year without paying Income Tax. For the tax year 2024/2025, this allowance is £12,570. Income above this threshold is taxed at the basic rate of 20%, with higher rates applicable for larger incomes.
Registering with HMRC and Filing a Self Assessment Tax Return
If your Amazon affiliate earnings exceed the £1,000 Trading Allowance, you need to:
- Register for Self Assessment: Inform HMRC that you’re earning self-employed income. This should be done by 5 October following the end of the tax year in which you earned the income.
- File a Self Assessment Tax Return: Annually report your income and expenses to HMRC. The deadline for paper returns is 31 October, and for online returns, it’s 31 January following the end of the tax year.
Allowable Expenses
When calculating your taxable profit, you can deduct allowable business expenses from your income. For affiliate marketers, these may include:
- Website Costs: Hosting fees, domain registration, and design expenses.
- Marketing and Advertising: Costs associated with promoting your affiliate links.
- Office Supplies: Stationery, software, and other necessary materials.
- Professional Services: Fees for accountants or consultants.
Keeping accurate records of these expenses is crucial for accurate reporting and potential tax relief.
National Insurance Contributions
As a self-employed individual, you may also be liable for National Insurance contributions (NICs):
- Class 2 NICs: Payable if your profits exceed the Small Profits Threshold (£6,725 for 2024/2025).
- Class 4 NICs: Payable on profits over £12,570 at 9% up to £50,270, and 2% on profits above that.
These contributions count towards your entitlement to certain state benefits, including the State Pension.

Recent Changes and Increased Scrutiny
Starting from January 2024, digital platforms, including Amazon, are required to report the earnings of their users to HMRC. This means HMRC will have direct access to information about your affiliate earnings, increasing the importance of accurate reporting.
Additionally, the threshold for filing a Self Assessment tax return is set to increase from £1,000 to £3,000 by 2029. This change aims to reduce the administrative burden on individuals with low levels of self-employed income.
Consequences of Non-Compliance
Failing to report your affiliate earnings can lead to penalties, interest on unpaid taxes, and potential investigations by HMRC. Given the increased data sharing between digital platforms and tax authorities, it’s more important than ever to ensure compliance.
Conclusion
In summary, if you’re earning money through the Amazon Affiliate program in the UK, it’s crucial to understand and fulfill your tax obligations. Monitor your earnings in relation to the Trading Allowance and Personal Allowance, register for Self-Assessment if necessary, and keep detailed records of your income and expenses. Staying informed and compliant will help you avoid penalties and ensure your affiliate marketing efforts remain profitable and stress-free.
