Are Cashback Rewards Taxable?

Are Cashback Rewards Taxable?

For the vast majority of UK shoppers, no—HMRC treats personal cashback as a price discount rather than income, so there’s nothing to declare. Tax considerations kick in only when cashback is earned on business or employer-funded spend (we cover those edge cases below).

“Free money” always raises eyebrows at tax time. With UK consumers expected to funnel over £18 billion through cashback programmes, it’s worth knowing when those extra quid in your wallet might trigger HMRC—and when they’re simply classed as a discount. Below we break down HMRC guidance, key business exceptions, and explain how Curve Pay cashback fits squarely in the non-taxable camp for everyday shoppers.


1. What Counts as “Cashback Rewards”?

Reward Type

Example

Payout Form

Credit/Debit Card Cashback

1 % monthly rebate on your Curve Pay spend

Statement credit or Curve Cash balance

Bank Account Rewards

£5 Barclays Blue Rewards

Cash deposit (often taxed at source)

Retail Cashback Sites & Apps

5 % back via TopCashback

Bank transfer or PayPal

Welcome Bonuses

£20 for opening a new card with no spend requirement

One‑off cash credit


2. HMRC’s General Rule: Personal Cashback = Discount, Not Income

HMRC’s Statement of Practice 4/97 and Business Income Manual confirm that cashbacks received by private individuals on their own spending are not taxable. HMRC views the reward as reducing the purchase price, similar to a shop coupon. (gov.uk)

Example: You buy trainers for £100 and receive £5 cashback. HMRC treats it as if the shoes cost £95—no income to declare.

7. FAQs

Q1: Do I include cashback in my Personal Savings Allowance?

No. Unless the bank labels it “interest” and deducts tax (rare post‑2023), cashback sits outside savings income.

Q2: I’m a sole trader—do I split personal vs business rewards?

Yes. Pro‑rate the cashback based on which expenses were business vs personal.

Q3: Does Curve Pay issue a tax statement?

Not needed for personal users; the app logs cashback amounts for reference. Business account holders can export CSVs.
