April 12, 2026 in United Kingdom — The fastest way to find out if your car is taxed is to use the free DVLA vehicle enquiry tool — no login, no fee, just your registration number. Whether you've just bought a used car, want to check your own vehicle, or are buying from a private seller and need to verify the vehicle is road legal, this guide shows exactly how to check if a car is taxed in under a minute.
How to Check if Your Car Is Taxed — Free DVLA Tool
The DVLA offers a free vehicle enquiry service at GOV.UK check vehicle tax. You only need the vehicle's registration number. The service tells you:
- Road tax status — taxed or untaxed, with the expiry date
- MoT status — current MOT certificate and expiry date
- CO2 emissions — the vehicle's official g/km figure
- Vehicle details — make, model, colour, fuel type, year of registration
Enter the registration number and the system returns the full status instantly. No account needed.
What Does the Check Tell You?
Taxed — What It Means
If the vehicle shows as taxed, it has a valid vehicle excise duty (VED) payment. The check shows the expiry date so you know when renewal is due. Being taxed doesn't automatically mean the vehicle is roadworthy — always check the MOT status too.
Untaxed — What It Means
An untaxed vehicle cannot be driven on any public road. If you're buying a car that shows as untaxed, budget for the tax immediately. Driving an untaxed vehicle — even to a garage — risks an £80 fixed penalty notice.
MoT Status
The check shows whether the vehicle has a valid MOT certificate. For a used car, check the MOT history separately at GOV.UK check MOT history to see pass/fail records and mileage consistency.
| Check Result | What It Means | Action Needed |
|---|---|---|
| Taxed, MOT valid | Vehicle is road legal | None — verify details match the car |
| Taxed, MOT expired | Illegal to drive | Book MOT immediately |
| Untaxed, MOT valid | Cannot drive, tax lapsed | Renew tax online immediately |
| Untaxed, MOT expired | Cannot drive at all | Book MOT, then tax |
| No record found | Vehicle may not be registered | Contact DVLA 0300 790 6802 |
Can I Check Any Vehicle's Tax Status?
Yes — you can check any UK-registered vehicle's tax and MOT status using just the registration number. You don't need to be the owner or keeper. This makes it invaluable when buying a used car privately. Always run the check before handing over any money.
What the Check Doesn't Tell You
The free DVLA check has important limitations:
- Outstanding finance — the vehicle may still have a loan against it
- Insurance status — a taxed car can still be uninsured
- Write-off history — the car may have been previously written off
- Stolen status — use the police database for this
For complete peace of mind on a used car purchase, use a paid HPI check or AA vehicle check (approximately £10–20).
How to Check If Your MOT and Tax Are Both Valid
Both checks are free on GOV.UK:
- Check vehicle tax and MOT — enter registration number
- Check MOT history — see full pass/fail record and mileage
What to Do If Your Car Is Untaxed
If your vehicle shows as untaxed:
- Renew online at GOV.UK vehicle tax — have your V5C reference and MoT certificate ready
- Tax takes effect immediately when you complete payment
- Allow up to 48 hours for the ANPR database to update
- Do not drive until tax is confirmed — the ANPR system may take time to update
Frequently Asked Questions
Is the car tax check really free?
Yes — both the vehicle tax check and MOT history check on GOV.UK are completely free. No registration, no login, no payment.
Can I check if a car I want to buy is taxed?
Yes. Simply ask the seller for the registration number and run the free check yourself. This is one of the most important steps before buying any used car.
My car shows as taxed but the reminder letter hasn't arrived. Is it definitely taxed?
Yes — the online system is the authoritative source. If it shows as taxed with a future expiry date, the vehicle is legal. If you're unsure, check again closer to the renewal date.
Can I tax a car without the log book?
You can tax a vehicle using the green new keeper slip (21-digit reference) while waiting for the full V5C log book to arrive. Both references work at GOV.UK.
Does a taxed car mean it has valid insurance?
No — tax and insurance are separate. A vehicle can be taxed but uninsured. Check with the Motor Insurance Bureau if you need to verify insurance status.
