Is PCP Compensation Taxable? UK Tax Guide
When you receive compensation for a mis-sold financial product, one question that often gets overlooked is whether HMRC will take a share of the payout. With PCP and HP redress payments potentially running into thousands of pounds, understanding the tax treatment is important. MotorRedress (www.motorredress.co.uk) has put together this guide to the UK tax position on motor finance compensation payments, drawing on HMRC's published guidance and the principles established for similar financial redress schemes.
The Three Components of PCP Compensation
As described in our other articles, PCP/HP redress under the FCA's CP25/27 framework has three components:
- Commission disgorgement: the return of the secret commission the dealer received from the lender
- Excess interest refund: the difference between what you paid and what you should have paid
- Restitutionary interest: 8% simple interest on components 1 and 2, from payment dates to settlement date
Each component has a different tax treatment.
Component 1: Commission Disgorgement — Not Taxable
The disgorgement of the secret commission is a restitutionary payment — it returns to you (via the lender) money that was taken from the value of your transaction without your consent. HMRC's general position on compensation payments is that if the payment compensates for a financial wrong (rather than providing a profit), it is not income and not subject to income tax.
For commission disgorgement, the position is clear: you are not receiving a profit or a gain — you are receiving back money that should not have been taken in the first place. This is analogous to the position on PPI compensation for the capital element.
Conclusion: Commission disgorgement is not subject to income tax or capital gains tax for individuals.
Component 2: Excess Interest Refund — Not Taxable
The refund of excess interest is similarly a restitutionary payment. You paid more interest than you should have, and you are receiving back the overpayment. HMRC's guidance on financial compensation treats the return of overpaid interest as capital, not income.
Important nuance: If you claimed the interest payments as a tax deduction (which would be unusual for a personal car finance agreement but may apply to self-employed individuals who used the vehicle for business), then the tax position of the interest refund may be different — the refund effectively reverses the deduction. Seek specialist tax advice in this situation.
For the vast majority of claimants with personal car finance for private use, the excess interest refund is not subject to income tax.
Conclusion: Excess interest refund is not subject to income tax for personal use agreements.
Component 3: Restitutionary Interest (8%) — Potentially Taxable
This is where the tax position becomes more nuanced. The 8% simple interest component is treated by HMRC differently from the principal compensation.
HMRC's published guidance (which draws on the PPI compensation precedent from 2011 onwards) treats the interest element of compensation payments as interest income for tax purposes. This is because the 8% interest represents money you have "earned" on your compensation claim — it is the time value of money you were deprived of.
Basic Rate Tax Deduction
Where lenders are required to pay 8% restitutionary interest, they are typically required to deduct basic rate income tax at source (currently 20%) and pay it to HMRC on your behalf. This means:
- If your total 8% interest component is £400, you would receive £320 net, with £80 deducted and paid to HMRC
- The lender will provide a certificate (an R185 or equivalent) showing the gross interest and tax deducted
Your Personal Tax Position on the Interest Component
The tax treatment depends on your individual circumstances:
| Situation | Tax Treatment |
|---|---|
| Non-taxpayer | You can reclaim the tax deducted (using form R40) |
| Basic rate taxpayer with Personal Savings Allowance available | May be covered by PSA (£1,000 for basic rate payers); reclaim if interest is within allowance |
| Basic rate taxpayer exceeding PSA | Tax deducted at source is correct; no further liability |
| Higher rate taxpayer (40%) | Additional 20% tax due on interest; report on self-assessment |
| Additional rate taxpayer (45%) | Additional 25% tax due on interest; report on self-assessment |
The Personal Savings Allowance
As of the 2025/26 tax year, the Personal Savings Allowance (PSA) allows:
- Basic rate taxpayers: £1,000 of interest income per year tax-free
- Higher rate taxpayers: £500 of interest income per year tax-free
- Additional rate taxpayers: £0 PSA
For most claimants receiving a single average-value claim, the 8% interest component will be well within the PSA — meaning no practical tax liability arises even on the interest element.
Example: An average claim of £700 over 10 years at 8% generates approximately £560 in restitutionary interest. Basic rate taxpayer with unused PSA: no net tax liability. Higher rate taxpayer with unused PSA: no net tax liability (within £500 PSA). Higher rate taxpayer with full PSA used: £560 × 20% = £112 additional tax due.
What About Business Users?
If your vehicle was financed partly or wholly through a business — particularly for sole traders or partnerships — the tax analysis is more complex:
- If the interest was claimed as a business expense, the refund of excess interest may be treated as business income in the year received
- The commission disgorgement element should still be capital in nature
- The restitutionary interest may be treated as business income
Business users should seek specialist tax advice from a qualified accountant. The position varies depending on the structure of the business and how the original finance was treated in the accounts.
Capital Gains Tax
Capital gains tax is not generally relevant to PCP compensation for personal vehicles:
- Private vehicles are exempt from CGT under HMRC's rules (they are "wasting assets")
- The compensation relates to the finance arrangement, not to a gain on the vehicle itself
- Restitutionary interest is income, not a capital gain
Conclusion: Capital gains tax does not apply to PCP compensation payments for private vehicles.
What HMRC Has Said (PPI Precedent)
HMRC's treatment of PPI compensation was clarified through guidance published in 2012 and updated since. The key principles, which carry across to motor finance DCA compensation:
- Compensation for the capital element (return of overpaid premiums/interest) is not income
- Compensation for consequential loss (e.g., financial distress) is not income
- The 8% interest component is treated as interest income and is subject to income tax
- Lenders are required to deduct basic rate tax from the 8% interest at source
There is no reason to expect HMRC to treat motor finance DCA compensation materially differently from PPI compensation, given the structural similarities in the redress framework.
Practical Steps for Claimants
When you receive your compensation: the lender should provide a breakdown identifying the principal (non-taxable) and interest (taxable) components separately.
Check whether tax was deducted: if your 8% interest component is over the de minimis amount where deduction is required, the lender will deduct 20% basic rate tax at source.
Non-taxpayers and those within PSA: complete HMRC form R40 to reclaim tax deducted if you are a non-taxpayer or if the gross interest falls within your remaining PSA.
Higher/additional rate taxpayers: include the gross interest amount in your self-assessment return for the tax year in which you received the compensation.
Keep your R185 certificate: the lender will issue this, and you will need it to complete the reclaim or self-assessment.
A Note on CMC Fees
If you used a claims management company, the fee they charge is paid out of your gross compensation — it is not deductible for tax purposes in the personal finance context. You are taxed on the gross interest received (before the CMC fee), not the net amount you ultimately retain.
Summary Table
| Component | Taxable? | Notes |
|---|---|---|
| Commission disgorgement | No | Capital restitution |
| Excess interest refund | No (personal use) | Return of overpaid amounts |
| 8% restitutionary interest | Yes — interest income | PSA may cover most claimants; basic rate deducted at source |
| Consequential loss element (if any) | Generally no | Specific advice needed |
Conclusion
For the great majority of UK consumers receiving PCP or HP compensation, the practical tax impact is minimal. The principal components of the redress (commission disgorgement and excess interest refund) are not income. The 8% interest component is taxable but usually falls within the Personal Savings Allowance. Higher and additional rate taxpayers should include the gross interest in their self-assessment.
