April 12, 2026 in United Kingdom — Selling a car in the UK entitles you to a car tax refund for any unused months of road tax remaining on the vehicle. The DVLA calculates this refund automatically from the day after the sale is processed. Many sellers don't realise they're owed this money — and many who do know don't understand how to claim it correctly. This guide explains exactly how the road tax refund process works, when the money arrives, and what to do if the DVLA hasn't processed it.
How the Car Tax Refund Works
Road tax in the UK (vehicle excise duty or VED) is paid in advance. When you sell your car and notify the DVLA, the vehicle's road tax is cancelled and the DVLA calculates a refund based on how many complete months remain on the tax period. The refund is pro-rata — if you paid for 12 months and sell after 3 months, you're owed 9 months back.
The refund is calculated from the day after the DVLA processes the notification of sale, not from the date you actually sold the car. This is why it's critical to notify the DVLA on the day of sale. The longer you wait, the more days of unused tax you lose.
How to Notify the DVLA of a Sale
The refund process begins when you notify the DVLA that you've sold the car. You can do this in two ways:
Online (Fastest and Recommended)
Go to GOV.UK sell your vehicle and enter your 11-digit V5C reference number plus the new keeper's details. This takes about 5 minutes and the refund is processed within 5 working days.
By Post
Fill in section 9 of your V5C log book (the 'sold or part exchange' section) and send it to the DVLA. This takes longer — allow up to 4 weeks for processing and refund.
When Does the Car Tax Refund Arrive?
Once the DVLA processes the notification online, the refund is typically issued within 5 working days. If you paid annually and have 9 months remaining, and your annual rate is £195, you should receive approximately £146 back (£195 × 9/12).
If you paid monthly by direct debit, the DVLA will cancel future payments and refund any overpayment already taken for the remaining period.
| Tax Payment Method | Refund Process | Time to Receive |
|---|---|---|
| Annual (card/bank transfer) | BACS refund to original payment card | 5 working days |
| 6-monthly instalments | BACS refund of unused portion | 5 working days |
| Monthly direct debit | Direct debit cancelled + refund of overpayment | 5 working days |
| Cash or cheque (historic) | BACS refund to bank account on record | Up to 4 weeks |
When Will You NOT Get a Road Tax Refund?
The DVLA only refunds complete unused months. If you have only a few days remaining in the current month, those days are not refundable. Additionally:
- DVLA direct debit cancellation without notification: If you simply cancel your direct debit without notifying the DVLA of the sale, you won't receive a pro-rata refund — you may actually owe money
- Written-off or scrapped vehicles: The refund process differs; contact the DVLA specifically for written-off vehicles
- Transfer to a family member (not a sale): Transfers within family may qualify for a refund if the tax period remaining is over 1 month
What If the DVLA Doesn't Process the Refund?
If it's been more than 6 weeks since you notified the DVLA and you haven't received a refund, contact the DVLA Vehicle Licencing team at 0300 790 6802. Have your V5C reference number and evidence of the sale ready (a signed receipt or delivery note with date).
If you sold the car privately and the new keeper has already taxed it in their name, the refund should still be processed for you — the two processes are separate. However, if the new keeper has taxed the vehicle and you didn't notify DVLA of the sale, you may face complications.
Claiming Car Tax Refund If You Forgot to Notify DVLA
If you've already sold the car but forgot to notify the DVLA, do it immediately at GOV.UK. The refund will be calculated from the date you notify them, not the date of sale — so the sooner you act, the more of your unused tax you recover.
Late Car Tax Penalty — Don't Risk It
If you forget to notify the DVLA and the car is still taxed in your name while being driven by the new owner, you're technically responsible for it. If the new owner drives without tax (because you didn't notify), both of you could face penalties. Always notify on the day of sale.
Frequently Asked Questions
Can I claim a road tax refund if I give my car to a family member?
Yes, but the process is treated as a transfer, not a sale. The refund is available if there are more than 30 days of unused tax remaining. Fill in the V5C transfer section and submit it to the DVLA to claim back the pro-rata amount.
What if I paid by cash decades ago and forgot about my car tax?
The DVLA has refund rules going back years. If a vehicle was taxed and is now off the road, contact the DVLA with the registration number to check if there's a refund owed. Road tax refunds generally have a 4-year limitation period.
Do I get a refund if my car is written off by the insurer?
Yes — but you need to notify the DVLA with the insurance write-off notification. The refund is processed from the date of the write-off, not from when you notify, so do it as soon as possible. You'll need your insurance certificate and the accident report details.
Can the buyer claim my unused road tax?
No. The refund goes to the person who paid — the seller. The buyer cannot claim any of the previous owner's unused road tax. This is why it's always worth checking how much tax is remaining before buying — it doesn't benefit the buyer, only the seller.
Conclusion
Car tax refunds in the UK are automatic once you notify the DVLA of the sale — but only if you notify them promptly. Use the GOV.UK online service on the day you sell to maximise the refund. Expect the money back within 5 working days of notification.
