Short answer: in the UK you can't claim car insurance against tax for ordinary personal driving or commuting. If you're self-employed or run a limited company and use the car for business, you may be able to claim the business share of the cost. You can't do that if you use HMRC's flat-rate mileage method, because that already includes insurance.

Can employees claim car insurance on tax?
No. If you're employed and drive your own car, you can't deduct the insurance premium. Commuting between home and your normal workplace isn't treated as business travel, so it doesn't qualify for relief.
If you use your own car for genuine business journeys, such as visiting clients, your employer can pay you approved mileage rates tax-free. These are 45p per mile for the first 10,000 business miles in a tax year and 25p per mile after that. If they pay less than that, you may be able to claim tax relief on the difference. These rates are designed to cover running costs, including insurance, so you don't claim insurance as a separate item.
Can sole traders and the self-employed claim it?
Often yes, but only for the business use of the car. If you're self-employed, you generally choose between two methods for each vehicle.
1. Simplified expenses (flat rate)
You claim a set rate per business mile, currently 45p for the first 10,000 miles and 25p after that for cars. This rate is meant to cover fuel, insurance, servicing, repairs and the cost of the vehicle itself. You can't claim your insurance premium on top of it.
2. Actual costs
You add up what you really spent and claim the business proportion. That can include:
- Insurance premiums
- Fuel
- Servicing, repairs and MOT fees
- Vehicle tax
- Capital allowances on the purchase price of the car
If you drive 60% of your miles for business, you can usually claim about 60% of the insurance. The private 40% isn't allowable. Keep a mileage log that shows the split.
What about limited company directors?
If the company owns the car and pays the insurance, the premium is generally a company expense. If the car is also available for private use, though, it is usually a taxable benefit in kind, which can mean extra tax for the driver and Class 1A National Insurance for the company. If you use your own car for company business, mileage rates are the normal route instead of claiming the insurance directly.
What you can't claim
- Insurance on a car used only for personal or family driving
- The private-use share of a car you also use for work
- Insurance costs covered by a flat-rate mileage claim
- Commuting to a permanent workplace as if it were business travel
Does a write-off mean you get the money back?
Not quite. A business expense reduces your taxable profit, so the saving depends on your tax rate. It doesn't refund the premium. Claiming £1,000 of allowable insurance saves you a portion of that, not the full £1,000.
Check your policy covers business use
Standard social, domestic and commuting cover doesn't normally include business use. If you drive for work, tell your insurer and get the right class of cover. Otherwise a claim could be disputed, whatever your tax position is.
Or did you mean an insurance write-off car?
The phrase write-off also means something different in the car world. When an insurer decides a car is uneconomical to repair, it is recorded as a write-off under the MIAFTR categories:
- Cat A: scrap only
- Cat B: break only, with the shell crushed
- Cat S: structural damage, repairable
- Cat N: non-structural damage, repairable
If you're buying a used car, a previous write-off can affect its value and may affect your insurance premium. You can check a vehicle's registration on motorpeek.com to see whether it has any recorded write-off history, along with other details such as MOT history, mileage records, stolen markers and outstanding finance.
Keep good records
If you claim car costs, keep your policy documents, receipts, a mileage log with dates and purposes, and notes on how you calculated the business percentage. HMRC may ask for evidence, and clear records make any claim easier to support.
Frequently asked questions
Can I claim my car insurance on my tax return if I commute to work?
No. Travel between home and a permanent workplace is treated as private, so the insurance for it isn't tax-deductible. Only genuine business journeys can potentially qualify.
Can self-employed people deduct car insurance in the UK?
Yes, if you use the actual costs method you can usually claim the business proportion of your premium. If you use HMRC's simplified mileage rates (45p per mile for the first 10,000 miles, then 25p), insurance is already included and can't be claimed separately.
Do I need business use cover to claim car insurance as an expense?
You should have it if you use your car for work beyond commuting, because standard cover often excludes business use. Tell your insurer how you use the car and keep records of your business mileage.
