How to Change Your Car Tax Class From Disabled

To change your car’s tax class from disabled to a standard class, take your V5C log book, MOT evidence, and payment to a Post Office branch that handles vehicle tax, or post the same documents to the DVLA in Swansea. You need to do this as soon as the vehicle stops qualifying for free disabled tax, because the DVLA treats an incorrectly taxed vehicle the same as an untaxed one.¹

When You Need to Change It

The disabled tax class attaches to the vehicle only while it is used by or for someone receiving a qualifying higher or enhanced rate mobility benefit. You are required to re-tax the vehicle in the correct standard class as soon as any of the following happens:¹

The disabled person’s qualifying benefit ends or drops to a rate that no longer qualifies.
You sell or transfer the vehicle. The new keeper doesn’t inherit the exemption.
The vehicle stops being used primarily for the disabled person, even if that person still receives the benefit.

Don’t wait for a reminder to arrive. The exemption ends when the qualifying condition ends, not when the DVLA notices.

Documents to Gather Before You Go

You don’t change the tax class by editing the V5C. The V5C records vehicle details; the tax class changes through the vehicle tax system.² What you actually need in hand:³

Your V5C registration certificate in your name.
Your V11 tax reminder if you’ve received one. It carries a reference that speeds up processing.
MOT evidence, if the vehicle needs an MOT. A certificate or the online history is fine.
Payment for the new tax rate.

If you don’t have a V5C in your name, complete a V62 (available at the Post Office or on GOV.UK) and bring the new keeper slip if you’ve recently bought the vehicle. If no V11 has arrived and your tax class is changing, use a V10 form instead; it’s designed for exactly this situation, where vehicle details have changed or there’s been a break in taxing.⁴

Changing the Tax Class at a Post Office

This is the quickest route. You can change the tax class at any Post Office branch that handles vehicle tax when your tax is due to run out or when you’re changing whether the vehicle is exempt, which is the case here.³ Not every branch offers vehicle tax services, so use the Post Office branch finder first.

Hand your documents to the clerk, pay the new rate, and the change is processed on the spot.

Changing the Tax Class by Post

If you can’t get to a participating Post Office, or if the vehicle’s body type or structure has also changed, send your paperwork to the DVLA. Include your V5C (or V62), your V11 or V10, MOT evidence, and a cheque or postal order for the correct amount. The address is:³

DVLA
Swansea
SA99 1BF

You can keep driving the vehicle while the postal application is being processed, so there’s no need to take it off the road in the meantime.³

What the New Tax Will Cost

Free disabled tax is being replaced by whatever standard rate your vehicle would otherwise pay. The figure depends on the vehicle type, its emissions, and when it was first registered. From April 2026, the main rates are:⁵

Cars first registered on or after 1 April 2017: £200 a year at the standard rate, or £210 by direct debit.
Cars with a list price over £40,000 at first registration: £640 a year for five years from the second licence, because a £440 additional rate sits on top of the standard £200.
Zero emission cars registered on or after 1 April 2025: £200 a year, with the same £440 additional rate applying if the list price was over £50,000.
Cars first registered between March 2001 and April 2017: taxed by CO2 band, from £200 for Band E up to £790 for Band M.
Private and light goods vehicles up to 3,500kg: £230 a year for engines up to 1549cc, or £375 for larger engines. Light goods vehicles are £360.

Motorcycles and tricycles have their own rate tables, generally lower.⁶

If the Car Won’t Be Driven, Use a SORN Instead

If the vehicle isn’t going to be used on public roads, you don’t have to pay for a new tax class at all. A Statutory Off Road Notification (SORN) tells the DVLA the vehicle is being kept off the road and removes the tax requirement until you tax it again or sell it.⁷ The car must genuinely stay on private property. Driving a SORN’d vehicle on a public road carries a maximum court penalty of £2,500 or five times the tax due, whichever is greater.⁸

What Happens After You Apply

Once the DVLA processes the application, you’ll receive confirmation that the tax class has changed, an updated V5C will be posted to you, and any refund due is sent automatically.³ The DVLA’s general guidance is around four weeks for a replacement V5C by post.⁹ When the new V5C arrives, destroy the old one so there’s no confusion if you later sell the vehicle.

What It Costs to Ignore the Change

The DVLA’s first move is usually an out-of-court settlement letter of £30 plus one and a half times the tax you should have paid. Ignore that and the case goes to a magistrates’ court, where the penalty rises to £1,000 or five times the tax due, whichever is greater.⁸ The out-of-court settlement is the cheapest way out once enforcement has started, but paying the standard rate on time is cheaper still. A tax class change worth £200 a year can turn into a bill of more than £1,000 if it drifts.
