Are Referral Bonuses Taxable in the UK? HMRC Guide

Understanding Tax on Referral Income in the UK

One of the most common questions we receive is whether referral bonuses are taxable. The answer depends on how much you earn and your overall tax situation. This guide provides clear, practical guidance based on current HMRC rules — though we always recommend consulting a qualified accountant for your specific circumstances.

The Short Answer

Referral bonuses are classified as miscellaneous income by HMRC. You have a £1,000 trading allowance per tax year (6 April to 5 April). If your total miscellaneous income — including all referral bonuses, cashback earnings, and similar payments — stays below £1,000, you owe no tax and do not need to report it.

If you earn above £1,000, you have two options:

1. Use the trading allowance: Deduct £1,000 from your total income and pay tax on the remainder.
2. Deduct actual expenses: If you have legitimate expenses related to your referral activities (internet costs, a portion of your phone bill, etc.), you can deduct these instead of the flat £1,000 allowance.

For most casual referrers earning under £1,000 per year, this means referral income is completely tax-free.

The £1,000 Trading Allowance Explained

The trading allowance was introduced by HMRC specifically to simplify reporting for small-scale miscellaneous income. Key points:

• It covers all miscellaneous trading income — not just referrals. If you also sell items on eBay, do the odd freelance job, or earn cashback, these all count towards the £1,000 limit.
• It is per person, not per activity. You get one £1,000 allowance covering all your miscellaneous income.
• It is separate from your Personal Allowance. The £12,570 Personal Allowance covers employment income. The £1,000 trading allowance is additional and specifically for miscellaneous/trading income.
• You cannot use both the allowance and claim expenses. It is one or the other — choose whichever gives you the better result.

When Do You Need to File Self Assessment?

You need to register for Self Assessment and file a tax return if:

• Your total miscellaneous income (including referral bonuses) exceeds £1,000 in a tax year
• You want to claim actual expenses rather than the trading allowance
• You are already registered for Self Assessment for other reasons

If you are employed and earn under £1,000 in referral income, you do not need to do anything. The trading allowance covers it automatically.

What Counts as Referral Income?

HMRC considers the following as taxable miscellaneous income:

• Cash bonuses: Direct payments to your bank account (e.g. £50 for referring someone to a bank)
• Account credits: Money added to your account balance that can be withdrawn
• Cash-equivalent rewards: Gift cards, vouchers with a clear cash value
• Free shares: The market value at the time they are awarded (investment referral bonuses)

Things that are generally not considered taxable referral income:

• Cashback on your own purchases: This is treated as a discount, not income
• Points or rewards that cannot be converted to cash: Loyalty points with no cash value
• One-off welcome bonuses for your own account: Bonuses you receive for signing up yourself (not for referring others)

How to Keep Proper Records

Good record-keeping protects you and simplifies tax filing. Here is what to track:

Essential Information per Bonus

• Date the bonus was received
• Company/programme name
• Amount received (in £)
• Type of bonus (cash, credit, shares)
• Whether it was a referrer bonus or a referee bonus

Simple Record-Keeping Methods

• Spreadsheet: A basic Excel or Google Sheets document with columns for date, programme, amount, and type. Update it each time you receive a bonus.
• Dedicated bank account: Some people open a separate account for referral income, making it trivially easy to track total earnings.
• Screenshots: Save confirmation emails and in-app notifications as backup evidence.

HMRC requires you to keep records for at least 5 years after the 31 January submission deadline for the relevant tax year.

Practical Examples

Example 1: Casual Referrer

Sarah earns £380 in referral bonuses during the 2025/26 tax year from various banking and investment app referrals. Because this is below the £1,000 trading allowance, she owes no tax and does not need to report it. She keeps a simple spreadsheet as a personal record.

Example 2: Active Referrer

James earns £2,400 in referral bonuses during the 2025/26 tax year. He uses the £1,000 trading allowance, so he pays tax on £1,400. As a basic-rate taxpayer (20%), he owes £280 in tax. He registers for Self Assessment and reports this on his tax return.

Example 3: Active Referrer with Expenses

Emma earns £3,200 in referral bonuses. She has £600 in legitimate expenses (portion of internet costs, phone bill, and subscription to tracking tools). She chooses to deduct actual expenses instead of the trading allowance, paying tax on £2,600. At the basic rate, she owes £520 — less than if she had used the flat £1,000 allowance (which would have meant tax on £2,200 = £440). In this case, the trading allowance is actually better, so she uses that instead.

Free Shares and Investment Referral Bonuses

Investment platform referral bonuses that pay in free shares have additional considerations:

• Income tax: The value of the shares at the time they are awarded counts as miscellaneous income (towards the £1,000 allowance).
• Capital Gains Tax: If you later sell the shares at a profit, the gain is subject to Capital Gains Tax (separate from income tax). You have a £3,000 annual CGT allowance (2025/26 rate).
• Timing matters: The taxable value is the market price when you receive the shares, not when you sell them.

National Insurance Contributions

If your referral income is classified as self-employment income (which it may be if you are actively and regularly promoting referral codes as a business activity), you may need to pay Class 2 and Class 4 National Insurance. However, for most people, referral income is occasional miscellaneous income and NIC does not apply. The distinction is based on whether HMRC considers it a trade — if in doubt, seek professional advice.

Summary: What You Need to Do

• Earning under £1,000/year: No action needed. The trading allowance covers it. Keep basic records.
• Earning £1,000–£5,000/year: Register for Self Assessment. Use the trading allowance or actual expenses. File by 31 January.
• Earning £5,000+/year: Consider speaking to an accountant. You may benefit from formal self-employment registration and expense deductions.
