You can remove an exemption from a vehicle if it’s no longer being used by a disabled person.
You can change your vehicle’s tax class at a Post Office that deals with vehicle tax if either:
you’re changing whether a vehicle is exempt from vehicle tax or not, eg it’s being used by a disabled person
the vehicle tax is due to run out (you’ve had a reminder or ‘last chance’ warning letter)
You need to take to the Post Office:
the V5C registration certificate (log book) in your name, or a new keeper supplement (V5C/2) if you’ve just bought the vehicle
your vehicle tax reminder letter (V11) if you have one
an MOT certificate that’s valid when the tax starts, or evidence if your vehicle’s exempt from an MOT (V112)
evidence of any eligibility for a disability exemption or reduction
an insurance certificate or cover note (only in Northern Ireland)
If you don’t have the V5C or V5C/2, download and fill in a V62 form. Take it to the Post Office with the £25 fee.
If you're applying for vehicle tax exemption for a new vehicle, you must take your exemption and insurance certificates to your dealership. For a ssed vehicle, change to free vehicle tax at a Post Office branch.
