Is My Car Taxed and MOT? How to Check Both at Once

Is My Car Taxed and MOT?

You can check both your vehicle tax and your MOT for free using your registration number. The government provides two quick online checkers, one for tax and one for MOT. Together they confirm whether your car is fully legal to be on the road.

Tax and MOT are two separate things that a car needs at the same time. Vehicle tax is a payment that lets you use the car on public roads, while the MOT is the yearly safety and emissions test. A car needs both to be driven legally, so it is worth checking the two together rather than assuming one covers the other. Our overview on What Is an MOT explains what the test side involves.

The two are also linked behind the scenes, which surprises some drivers. When you try to tax a car the system checks it has a valid MOT first. That means an expired MOT can stop you taxing the car, so keeping the test current is the key that unlocks everything else.

Checking Tax and MOT in Two Minutes

Both checks are free and need only your registration. The steps below run through confirming each in turn.

Doing both at once takes only a couple of minutes and gives you complete peace of mind. If you only want to confirm the MOT side, our guide on Is My Car MOT covers that check on its own.

Why You Cannot Tax a Car Without an MOT

The reason tax and MOT are so often checked together is that they depend on one another. The tax system will not usually let you tax a car that does not have a valid MOT, because the law expects a car on the road to be both roadworthy and taxed. This link is deliberate and it keeps untested cars off the road.

The practical takeaway is to treat the MOT as the first domino. Get the test done and the rest falls into place. Our guide on Taxing a Car Without MOT explains the rule in full for anyone caught in this situation.

What to Do if Your Car Is Not Legal

If your check shows the MOT or the tax has run out, the car is not legal to drive on the road. The fix is straightforward. Book an MOT to get the car tested and passed, then tax it once the valid MOT is in place. Only two journeys are allowed in the meantime, to a pre booked test or to a garage for repairs.

If the car is not being used at all, you have another option. You can declare it off the road with a SORN, which pauses the need for tax and MOT while the car is kept on private land. Our guide on When Your MOT Expires helps you confirm exactly where your MOT stands before you decide.

Does a New Car Need Tax and MOT?

A common source of confusion is a brand new car. A new car still needs to be taxed and insured from the very start, yet it does not need an MOT until it is three years old. So for the first three years the tax checker will show a taxed car while the MOT checker shows no test on record, which is perfectly normal.

Once the car reaches three years old the MOT joins the picture and both need keeping current from then on. It is worth noting the three year date in advance, since the car will have been legal without an MOT up to that point and the change is easy to overlook. After the first test the annual pattern settles in for the life of the car.
