V12 Vehicle Tax Form: Exemptions, Payment, and Penalties

The V12 vehicle tax form is the paper application you complete at a Post Office when the DVLA’s online and phone tax services will not work for your situation. You need it in three main cases: when you have neither a V11 reminder nor a V5C logbook to give the electronic system a reference number, when you are moving the vehicle into a new tax class for the first time (such as disabled or historic), and when the vehicle’s specifications have changed in ways the DVLA record does not yet reflect. Every other route to tax a vehicle depends on reference numbers the automated systems can look up, so if yours cannot be found, the counter is the only way through.

When the V12 Is Your Only Option

The online service and the 24-hour phone line both pull your record using a number from either the V11 reminder letter or the V5C registration certificate. Without one of those documents in hand, neither service can identify your vehicle, and you are pushed to the paper form. Logbooks go missing during house moves, and V11 reminders sometimes never arrive.

A first-time change of tax class also has to go through the Post Office. The most common example is moving a used vehicle into the disabled tax class. If you qualify for certain disability benefits and want free vehicle tax, you have to apply in person with your certificate of entitlement to the qualifying benefit alongside your logbook or a V62 replacement application.¹²

The third trigger is a vehicle whose details have changed in a way the DVLA has not caught up with. Modifications to engine capacity, fuel type, or body structure can shift the vehicle into a different tax band. Until the record is updated, the electronic system blocks the transaction and directs you to paper so a person can review the change.

What to Bring to the Post Office

Turn up with anything missing and you will be sent away. Gather:

Your V5C registration certificate (logbook) in your name. If you have just bought the vehicle, the green new-keeper slip from the previous owner’s V5C stands in for it.
Your V11 reminder letter if you have one. It speeds things up but is not required when you have the V5C.
A valid MOT. It must be recorded in the national database, which you can check free on GOV.UK. In Northern Ireland, you have to present a physical MOT certificate that is valid on the date the tax starts.²
An insurance certificate or cover note, in Northern Ireland only. The rest of the UK does not require this at the counter.³

No V5C at all? You will need to file a V62 application for a replacement logbook at the same time. The fee is £25, and the replacement usually arrives within four weeks by post, though it can take longer if you are being registered as a new keeper for the first time.⁴

Filling in the Form

Blank V12s are held behind the counter at any Post Office branch that handles vehicle tax. The form asks for your vehicle’s registration number, make, and model, and for the tax class you are applying for. Common classes include Petrol Car, Private/Light Goods, and Disabled. Enter them exactly as they appear on your V5C or in the instructions printed on the form.

You also have to give a start date. VED always starts on the first of a month, so a mid-month date is not an option. Fill in your personal details carefully, because the name on the form has to match the name on your V5C or on the identification you show at the counter. A mismatch is one of the most common reasons applications get rejected, and fixing it means another trip.

Paying at the Counter

You can pay by cash, debit card, or credit card. You can also set up a Direct Debit at the counter, which splits the cost into monthly or six-monthly instalments instead of a single upfront payment.⁵

Spreading payments carries a 5% surcharge on top of the annual rate. Paying yearly by Direct Debit has no surcharge.⁵ Direct Debit cannot be set up on a bank account that requires two signatures. Whichever way you pay, the clerk gives you a receipt as temporary proof. The DVLA database usually reflects the new tax within five working days.

What you owe depends on when the car was first registered, its CO2 emissions, and its fuel type. Cars first registered on or after 1 April 2017 pay a first-year rate based on emissions and then a flat standard rate from year two, currently £200 for most cars.⁶ Petrol or diesel cars with a list price above £40,000 when new pay an extra £440 a year for five years starting from year two. The equivalent threshold for zero-emission cars is £50,000. Electric and zero-emission cars are no longer free to tax: those registered from 1 April 2025 pay £10 in the first year and then £200; those registered between April 2017 and March 2025 also pay £200; those registered between March 2001 and March 2017 pay £20.⁷

Using the V12 to Claim an Exemption

Two of the most common reasons people fill in a V12 result in a £0 payment. Exempt does not mean skipping the process; the vehicle still has to be taxed, but no money changes hands.

Disabled Tax Class

To move a used vehicle into the disabled class for the first time, you apply at the Post Office with your V5C (or a V62 if the logbook is missing), your certificate of entitlement to the qualifying benefit, and evidence of a valid MOT.¹

Historic Vehicle Exemption

Classic cars qualify for free tax under a rolling 40-year rule. From 1 April 2026, vehicles built before 1 January 1986 are eligible; if the exact build date is unknown but the vehicle was first registered before 8 January 1986, it still qualifies.⁸ Bring your V5C in your name, your V11 if you have one, and evidence of a current MOT or a V112 declaration if the vehicle is MOT-exempt. A missing logbook again means filing a V62 with the £25 fee.³

Keep the vehicle taxed at its existing rate while the application is processed if you plan to drive it. The DVLA takes the logbook away for updating and issues a new one showing the historic class. Any refund owed for months already paid at the standard rate arrives automatically; contact the DVLA if it has not come through within six weeks of your updated logbook.³

If You Are Not Going to Use the Vehicle

The V12 is for taxing a vehicle. If you are stopping instead, that is a different route. To take a vehicle off the road, file a Statutory Off Road Notification (SORN) with the DVLA. A SORN declares the vehicle will be kept off public roads entirely, and you cannot drive it anywhere on a road until you tax it again.⁹

You can SORN online with the 11-digit number from your V5C or the 16-digit reference from a V11, by phone on 0300 123 4321, or by posting a V890.⁹ If you have sold, scrapped, exported, or SORNed the vehicle, or had it written off or stolen, any full months of tax already paid come back to you as a cheque sent to the name and address on the logbook. Partial months are not refunded, and the refund excludes credit card fees, the 5% Direct Debit surcharge, and the 10% surcharge on single six-month payments.¹⁰ The DVLA calculates the refund from the date it receives your notification, not the date you stopped using the vehicle, so acting quickly matters.

What Happens If You Skip It

Every vehicle has to be either taxed or covered by a SORN at all times. The DVLA runs Automatic Number Plate Recognition cameras against the tax database, and enforcement is largely automated. The first step is a Late Licensing Penalty of £80, reduced to £40 if you pay within 33 days. Ignore it and the DVLA issues an out-of-court settlement of £30 plus one and a half times the outstanding tax, with the vehicle liable to be clamped. Driving a SORNed vehicle on a public road pushes the settlement to £30 plus twice the outstanding tax, and unpaid cases go to a magistrates’ court where the maximum fine is £1,000 or five times the tax owed, whichever is greater (£2,500 for driving with a SORN in force).¹¹ There is no quiet grace period; the system checks constantly.
