Road Tax Online: How to Tax Your Vehicle

Enter a registration to see vehicle tax status, the tax due date and MOT expiry. Free, instant.

Enter a UK number plate, for example AB12 CDE

You can pay road tax online on GOV.UK in a few minutes, at any time of day, using the vehicle's registration number and a reference from the V5C logbook or a reminder letter. Road tax is the everyday name for vehicle excise duty (VED), and the DVLA records it against the vehicle, not the owner. The vehicle must be insured and, if it is old enough, have a valid MOT before you can tax my car online successfully.

Part of Vehicle Tax. Start with the main guide: Vehicle Tax Status Check

Updated October 2026 · Independent information, not legal advice

Whether you are taxing a first car, renewing after a reminder, buying a second-hand van or sorting out a bike, the steps are similar. The details that trip people up are the paperwork, the start date, the payment method and what happens when you change vehicle. Below, each part is covered in plain English, with the official GOV.UK service as the final authority for rates and rules.

What Road Tax Actually Is

Road tax is a legal requirement for most vehicles used or kept on public roads in the UK. It is formally called vehicle excise duty, shortened to VED, and is collected by the DVLA.

The short definition

VED is an annual charge linked to the vehicle. It is not a licence to drive, and it is separate from insurance and the MOT. All three are checked separately by different bodies.

Why the name confuses people

"Road tax" and "car tax" are popular labels. The official label is vehicle tax. All three mean the same charge, so searches for vehicle tax online and "road tax online" lead to the same GOV.UK service. Whether you want to pay car tax, pay vehicle tax, pay car tax online or pay vehicle tax online, the route is the same: the official service, using the vehicle's registration.

What Does Road Tax Pay For?

Many drivers ask what does road tax pay for. VED goes to the government and is not ring-fenced for one single purpose in the way the old tax disc suggested.

General funding, not a garage bill

In general terms the money supports public spending, including roads, but it does not cover your repairs, your MOT or your insurance. Check GOV.UK or the Treasury's published explanations for the current arrangements.

Why it is still due on a quiet road

Tax is due because the vehicle is kept on a public road, not because of how far it travels. A car parked outside your house still needs tax, or a SORN.

Who Has To Tax A Vehicle

Nearly every registered vehicle needs to be taxed, or declared off the road, from the day it is registered.

  • Cars, vans and motorhomes used or parked on public roads
  • Motorbikes and mopeds, including small engines in most cases
  • Trailers are usually handled differently, so check the official guidance
  • Company cars, where the company as the registered keeper is responsible
  • Imported vehicles once registered with the DVLA

Vehicles that may not need paying for

Some vehicles are exempt or pay nothing, such as certain disabled-keeper vehicles and vehicles of historic interest. Exempt does not always mean "no paperwork": you may still need to renew the exemption or confirm it each year.

What You Need Before You Start

Preparing first saves a failed attempt. Gather the following before opening the service.

  • The vehicle registration number
  • The 11-digit reference number from the V5C logbook, or the reference on a reminder letter
  • A valid bank card or direct debit details
  • Proof the vehicle is insured, although the DVLA normally checks this automatically
  • A valid MOT, unless the vehicle is exempt

Checking the vehicle details first

Enter the reg into the free MOT history checker to confirm the make, colour, fuel type and MOT status. If anything differs from what you expected, find out why before you pay.

Step By Step: Tax My Car Online

Here is the process most keepers follow.

  1. Open the vehicle tax service on GOV.UK and choose to tax the vehicle.
  2. Enter the registration number.
  3. Enter the V5C reference number or the reminder reference.
  4. Confirm the make and model shown match the vehicle.
  5. Choose the payment frequency: annual, six months or monthly by direct debit where available.
  6. Pay, and keep the confirmation email.

What happens straight after

The DVLA updates its record almost immediately. You do not get a disc to display, and there is nothing to print for the windscreen.

Do I Need A V5C To Tax A Vehicle?

Often you need the V5C details, but not always. The V5C is the logbook, and the reference number on it is the quickest way to prove you are the keeper.

If you are the new keeper

The new keeper section of the V5C, sometimes a green slip, has a reference you can use. If you have neither, read about how to tax a car without a V5C.

If the logbook is lost

Apply to the DVLA for a replacement. Until it arrives, other proof routes exist, and the official guidance describes them.

Paying With Direct Debit Or Card

Pay road tax by card for a single payment, or by direct debit to spread the cost. Both are offered on the online service for most vehicles.

Direct debit basics

A direct debit is taken monthly or as a set instalment, and the vehicle stays taxed while it runs. The total paid can be slightly higher than a single annual payment, so check the current terms on GOV.UK.

Card payment basics

Paying once is simple, and most people then diarise the when does my tax run out date or rely on the reminder.

Credit cardOne-off paymentCheck for any card charges

How Much Is My Road Tax?

The honest answer is that it depends on the vehicle. How much is my road tax is set by the age, fuel type, emissions and sometimes the list price or engine size.

Drivers often ask how much road tax for my car they should expect, or how much car tax will I pay when the tax is due. The vehicle's registration lets the official service work out the answer for you before you pay.

Why no single figure exists

Different vehicles sit in different groups, and the car tax rates are published by the government and reviewed regularly. No rate is quoted here because it may be out of date by the time you read it.

Where to find the right rate

Use the DVLA's vehicle enquiry service, the tax service itself, or a car tax calculator to see what applies to your registration.

What Tax Band Is My Car?

What tax band is my car depends on when the car was first registered.

  • Registered before March 2001: usually based on engine size
  • Registered from March 2001 to March 2017: usually based on CO2 emissions, arranged in tax band letters
  • Registered from April 2017: a first year rate based on CO2, then a standard rate

Finding the band quickly

The registration check shows the year of manufacture, fuel and CO2 figure where recorded. That is enough to know which set of rules applies. If in doubt, ask the DVLA.

What Tax Class Is My Car?

What tax class is my car is a different question from the band. The tax class describes the category of vehicle for taxing, for example private/light goods, motorcycle or historic.

Why class matters

The tax class decides what rules and rates the DVLA applies. A van registered as light goods may be taxed differently from a car, which is why people searching to tax my van should check the class first.

The First Year Rate

Vehicles first registered on or after 1 April 2017 pay a first year rate when first taxed.

What affects it

The first year rate depends on the CO2 emissions recorded for the vehicle, which is usually set when it is registered. The dealer often includes it in the price, but it can appear separately.

What changes afterwards

After the first year the standard rate normally applies. Check the current arrangement on GOV.UK, including any special position for electric vehicles.

The Standard Rate

After the first year a single flat standard rate generally applies to cars registered from April 2017.

Possible extras

Some cars also pay the expensive car supplement, described below. The standard rate is not the same for every vehicle type, so always check for your vehicle.

The Expensive Car Supplement

The expensive car supplement is an extra charge that can apply to cars with a higher list price when new.

Who might pay it

It usually applies for a limited number of years after the first year rate, and the trigger is the list price rather than what you paid. The expensive car supplement has its own rules, so check them on GOV.UK before assuming it applies.

Electric Vehicles And Road Tax

The rules for electric vehicle tax have been changing, so do not assume an EV is free of tax.

Old assumption versus current position

For years zero emission cars paid nothing. Government policy has moved, and the position has been reviewed in recent budgets. Confirm the current rules on GOV.UK for your registration date.

Why it matters when buying

If you are buying a second-hand EV, look at the vehicle's tax record and the current rules, not what the seller remembers.

Cars With No Road Tax To Pay

A small number of vehicles pay nothing. See cars with free road tax for examples and the conditions that go with them.

Do not assume

Exemption usually depends on the specific vehicle and keeper. Check it on the DVLA service rather than relying on a listing or an old article.

Older Car Tax UK Rules

Older car tax UK rules are more generous but not unlimited.

Vehicles of historic interest

Vehicles first registered at least 40 years ago (rolled forward each year) can often be claimed as exempt, typically if the vehicle has not been substantially changed. You usually still need to claim the exemption with the DVLA.

Older but not historic

A 25-year-old car is often taxed on emissions or engine size like any other. Age alone is not an exemption. See MOT age exemption for the separate MOT rule.

Tax A Motorbike

To tax motorbike models, the same online service is used.

How motorbikes are taxed

Motorcycle tax is usually based on engine size, not emissions, and rates depend on the capacity band. The motorcycle road tax figure is published on GOV.UK.

Practical steps

Enter the reg, the V5C reference, pay by card or direct debit and keep the confirmation. Check the motorbike MOT guide too, because the MOT has separate timing.

Motorbike Road Tax Myths

  • "Small bikes are always free." Not reliably, so check the engine size and class.
  • "Bikes only need tax in summer." No, it is due whenever the bike is on the road, or it needs a SORN.
  • "A trike is taxed like a bike." It depends on the category, so check the registration.

Tax My Van

Anyone who needs to tax my van follows the same online path, but the class matters.

Light goods versus car-derived vans

Vans may fall under light goods rules with a different structure from cars. The DVLA record shows the class.

Company and fleet vans

The registered keeper, often a company, is responsible. Fleet managers should diarise each renewal date.

Changing Car And Road Tax

Car tax change of car is a frequent point of confusion. Tax belongs to the vehicle, so when you sell a car its tax does not go with you.

Selling

Tell the DVLA you have sold it. The DVLA normally refunds any full remaining months automatically.

Buying

The new keeper must tax the vehicle before driving it. There is no tax carried over from the previous owner.

Part-exchange

A dealer taking your car in part exchange should also notify the DVLA. Check the record later to make sure it happened.

Buying A Used Car And Road Tax

When a car changes hands, the tax status can surprise you.

  • Tax is not transferred with the car
  • Seller refunds are handled by the DVLA, not between the two of you
  • A car bought untaxed should stay off public roads until you tax it
  • A vehicle tax status check on the reg shows the current position

Practical advice

Ask for the V5C, check the reg online, and tax the vehicle before you drive away, or arrange transport.

Renew Car Tax

To renew car tax, use the same service. You will often get a reminder letter or email, but you should not rely on it.

When to renew

You can normally renew within a short window before expiry and keep the same cover. Check GOV.UK for the current rule.

Renewing with no reminder

You only need the registration number and the V5C reference. The reminder is a convenience, not a requirement.

Buy Road Tax For A Short Period

People ask how to buy road tax for a few months only.

Options usually available

Six-month and monthly payment options exist for many vehicles, but a short period is not the same as a pro-rata charge. Check the options offered for your vehicle.

Why monthly may cost more overall

Spreading the payment tends to cost slightly more than a single annual payment. Decide whether the flexibility is worth it.

When Does My Tax Run Out?

The simplest answer to when does my tax run out is on the DVLA's vehicle enquiry service.

What to look for

It shows the tax status and expiry date from the registration. The vehicle tax status check is useful before buying or lending a car.

Setting a reminder

Put the date in your phone calendar and watch for the DVLA email or letter, but remember the legal duty to tax stays with you.

Vehicle Tax Reminder Letters

A vehicle tax reminder is sent by the DVLA before the tax ends, typically by post or email if you have registered.

What the reminder contains

It gives the vehicle details and a reference for renewing. You can use it instead of the V5C reference.

If you never get one

Not receiving a reminder is not a defence. Check the registered address is correct, and read about how to change your address for car tax.

Is Car Tax Going Up In April?

Many drivers ask is car tax going up in april, and how much is road tax going up.

How rates usually change

Rates are commonly reviewed once a year and any change typically takes effect from April, but the rates themselves depend on the government's decisions.

Keeping up to date

Read budget car tax changes and the GOV.UK vehicle tax rates pages. No rise or fall is assumed here.

Car Tax Changes You Might Hear About

Headlines about car tax changes often mix proposals with confirmed rules.

Telling the difference

Look for the date a change takes effect and the official source. Until a change has started, treat it as an announcement.

Why it matters to you

If you are about to buy a car, check which rate group it will fall into at the time you first tax it. Read why car tax can rise for wider context.

Continuous Insurance And Taxing A Car

The DVLA operates Continuous Insurance Enforcement. A registered vehicle must be insured unless it has a SORN.

The insurance link

Online taxing usually checks that the vehicle is insured against the Motor Insurance Database. You can look at how this works in tax a car without insurance.

Checking cover

Use the insurance check guidance to see whether a vehicle shows as insured.

MOT And Road Tax

You usually cannot tax a car that needs an MOT without a valid one.

How the online check works

The DVLA checks the MOT records directly. If your MOT is missing or expired, the tax service may refuse the payment.

What to do

Book the test, then tax. See when your MOT is due if you are unsure, or confirm it with an MOT check.

SORN: When You Do Not Tax

If a vehicle is not being used or kept on a public road, you can make a SORN instead.

What SORN means

SORN stands for Statutory Off Road Notification. It is a declaration that the vehicle is off the road, which also stops tax. Read how to SORN your car for the process.

Mixing up SORN and cancelling

Making a SORN is not the same as cancelling road tax. Both affect refunds, so read the official guidance.

Taxed, SORN and untaxed vehicles compared
StatusCan drive on roadUsually needs
TaxedYesTax and insurance
SORNNoOff-road storage
Untaxed, no SORNNoRisk of penalties
ExemptYesCheck GOV.UK rules

Road Tax In Northern Ireland

Vehicle tax NI questions depend on where the keeper lives and on the vehicle.

Who handles what

Vehicle tax is managed through the DVLA, but the MOT in Northern Ireland is run separately by the DVA. See DVLA in Northern Ireland.

Moving between regions

If you move a vehicle to or from Northern Ireland, update your address with the DVLA and follow the official steps.

Paying For Multiple Vehicles

Households and small businesses often tax more than one vehicle.

  • Each vehicle has its own record and its own renewal date
  • A calendar note for each reg helps
  • Direct debits are set up per vehicle
  • Sharing one reminder email is fine, but check each entry

Fleets

A fleet manager may prefer a spreadsheet with tax, MOT and insurance dates side by side.

What Happens If You Do Not Tax

Driving an untaxed vehicle is an offence.

Possible consequences

The DVLA can issue a penalty, the vehicle can be clamped, and in some cases it can be removed. The amount is not stated here; see GOV.UK.

Do not ignore letters

Reply to DVLA letters quickly. If you have sold the vehicle, tell them. Ignoring letters usually makes things worse.

Late, Lapsed And Forgotten Tax

Sometimes tax lapses by accident.

What to do straight away

Keep the vehicle off public roads if it is untaxed, tax it online, and do not assume a short gap is harmless.

Gaps between keepers

A vehicle may show as untaxed between owners. Check its status before you buy. A full MOT check can warn about other problems too.

Refunds When You Sell Or SORN

The DVLA usually refunds tax for whole months left unused when the vehicle is sold, scrapped or declared SORN.

Automatic versus manual

Refunds are usually sent automatically to the bank details held or by cheque. You may need to contact the DVLA if the record is unclear.

Refunds on direct debit

Direct debit payments stop when you notify the DVLA. Check your bank statement afterwards.

Changing Your Address

If you move house, tell the DVLA so reminders reach you.

Why it matters

Reminders, penalty letters and refunds go to the address on the record. See how to change your address for car tax.

Updating the V5C

The V5C holds the registered address and is updated through the DVLA, not through your insurer.

Importing A Vehicle

Imported vehicles are taxed only after DVLA registration.

Steps to think about

Register first and receive the registration documents. Then tax online as normal. The car import check can help identify whether a car was imported.

Watch for gaps

Imported records may have less history, so check the MOT and tax carefully.

Four-By-Fours And Low-Tax Vehicles

Some people look for lower-tax larger vehicles.

Reading the rules

What counts as low tax depends on the class and emissions. Read about 4x4 vehicles with low road tax and check the current tax class.

Common Mistakes When Paying Online

Most failed attempts come from a handful of mistakes.

  • Mistyping the reg or the 11-digit reference
  • Using an old V5C reference after a change of keeper
  • Having no valid MOT at the time
  • Not being insured, or the insurer not yet showing on the Motor Insurance Database
  • Using an unofficial website that charges a fee

Fake sites

The official service is on GOV.UK. Be cautious of third-party sites that charge extra for what GOV.UK does directly.

Scams And Warning Signs

Scams often imitate the DVLA.

  • Text messages asking for payment details
  • Emails about refunds with links
  • Websites imitating GOV.UK

What to do

Do not click a link in an unexpected message. Go to GOV.UK directly or use your own saved bookmark.

A Quick Reference Checklist

Before you click pay, tick these.

  • Reg number checked
  • V5C reference to hand
  • MOT valid or exempt
  • Insurance in place
  • Payment method chosen
  • Confirmation saved

After paying

Check the new expiry with a tax status check in a day or so, and note the date.

Where The Official Answers Live

The DVLA and GOV.UK are the final authority on vehicle tax. This independent information service is not the DVLA.

What the free lookup can show

The free lookup shows tax status and due date from DVLA data, with MOT history, but not insurance.

When to contact the DVLA

Contact them if a record looks wrong, a refund is missing, or you are unsure of an exemption.

Keeping your own records

Save the confirmation email, note the date tax runs out, and keep the V5C somewhere safe. If a dispute ever arises about whether a vehicle was taxed on a given day, your payment record and the DVLA's own history are the evidence that matters. A photograph of the V5C reference can also save a trip when you next renew.

A final sense check

If any part of the process feels unusual, such as a demand for extra fees or an unfamiliar web address, stop and start again from GOV.UK. The real service is straightforward, and a vehicle that is insured, tested where needed and correctly registered is usually taxed in a few minutes.

Scenarios: Which Route Fits Your Situation

Real situations rarely match a textbook, so here are the common ones and the usual way through each.

You have just bought a used car

  • Check the record first, because the vehicle may show as untaxed from the moment the previous keeper sold it.
  • Use the new keeper reference from the V5C, or the green slip, to tax online.
  • Insure it before you tax it, since the online service normally looks for cover.
  • Confirm the MOT is valid so the payment is accepted.
  • Do not drive it home untaxed; arrange collection if any step is missing.

You are taxing a car you have not used for months

  • Check for a SORN, because a vehicle declared off the road must be taxed again before use.
  • Tax it online with the reg and V5C reference.
  • Look at the MOT date, which may have run out while the car sat unused.
  • Re-insure the car before it goes back on a public road.

You are a company keeper

  • Keep a dated list of every vehicle with tax, MOT and insurance dates.
  • Use one named person responsible for renewals.
  • Update the registered address when the business moves.
  • Cancel or SORN vehicles leaving the fleet promptly.

Questions To Ask Before You Pay

A short pause avoids most mistakes.

For yourself

  • Is the reg typed correctly with no letter and number mix-ups?
  • Does the vehicle description match the car in front of you?
  • Is the start date right, rather than earlier or later than needed?
  • Is it the right payment plan for your budget?

For the seller of a used vehicle

  • Has the DVLA been told about the sale?
  • Is the V5C handed over with the new keeper section completed?
  • Is any refund on its way to the seller and not expected from you?

Mistakes That Cost People Money

Small errors can turn into penalties or wasted payments.

  • Paying a third-party website that adds a fee for a free service.
  • Forgetting the direct debit when you sell, then seeing payments continue.
  • Assuming the reminder is optional to act on, when the legal duty remains yours.
  • Taxing the wrong vehicle because of a typed reg.
  • Leaving a car untaxed on the road after a failed payment.
  • Not checking the tax class for a van or converted vehicle.
  • Skipping the MOT then finding the tax payment is rejected.

What to do if you pay in error

Contact the DVLA quickly. Do not assume a refund will arrive without a claim, and keep the confirmation email and bank record.

Key Terms In Plain English

Plain definitions help when the forms use jargon.

  • VED: vehicle excise duty, the official name for road tax.
  • V5C: the registration certificate, often called the logbook.
  • SORN: Statutory Off Road Notification, used when a vehicle is not on the road.
  • First year rate: the charge for a car registered from April 2017 in its first year.
  • Standard rate: the flat charge that usually applies afterwards.
  • Tax disc: the paper disc once shown on the windscreen, no longer used.
  • Tax band: the emissions-based group used for cars registered from 2001 to 2017.
  • DVLA: the agency that keeps vehicle records and collects the tax.

Where to go next

After you pay, a quick MOT history checker lookup shows the MOT side of the same vehicle.

Frequently Asked Questions

How do I pay road tax online?

Go to the vehicle tax service on GOV.UK, enter the registration number and the reference from the V5C or a reminder letter, confirm the vehicle details, choose annual, six-monthly or monthly payment where offered, and pay by card or direct debit. The vehicle needs insurance and, if old enough, a valid MOT. Keep the confirmation email. No disc is issued.

Can I tax my car online without a V5C?

Often yes, if you have another reference such as the DVLA reminder letter or the new keeper slip. If you have none of these, you can usually ask the DVLA for a replacement logbook and use the official guidance on taxing without one. Avoid unofficial websites that charge extra for this help, as the official service itself is free to use.

How much is my road tax?

It depends on the vehicle: its age, fuel type, CO2 emissions, engine size, and sometimes its list price. Rates are set by the government and reviewed regularly, so a figure quoted elsewhere may be out of date. Enter your registration into the official vehicle tax service or a car tax calculator to see the current rate for your vehicle.

What does road tax pay for?

Vehicle excise duty goes into general government funds and is not reserved for one purpose such as repairing your local road. It is separate from your MOT, insurance and any repair costs. For a current explanation of how the money is used, check GOV.UK or Treasury publications, because spending arrangements can change.

Does road tax transfer when I sell my car?

No. Vehicle tax is tied to the vehicle but is not transferred to the new keeper. When you sell, tell the DVLA. It normally refunds any full remaining months. The buyer must tax the vehicle before driving it. Do not assume the new owner will do it for you, and check the DVLA record afterwards.

Can I pay road tax monthly?

Usually yes, using a direct debit, and annual or six-month payments are also available for many vehicles. Spreading payments generally costs a little more than paying once, so compare the options on GOV.UK. Direct debit is normally set per vehicle. If you sell the vehicle or SORN it, tell the DVLA so payments stop.

Do I need an MOT to tax my car?

Normally yes, if the vehicle is old enough to need one. The DVLA checks MOT records when you tax online, so an expired or missing MOT can stop the payment. Some vehicles are exempt from the MOT. Use an MOT check on the registration to confirm the expiry date before you try to tax.

Do I need insurance to tax a car?

Yes, in most cases. Under Continuous Insurance Enforcement a registered vehicle must be insured, or covered by a SORN. The online service usually checks the Motor Insurance Database as you tax. If your insurer has not yet updated the record, you may need to wait or contact them.

How do I tax a motorbike?

Use the same GOV.UK vehicle tax service with the registration number and the V5C reference. Motorcycle tax is usually based on engine size, and you can normally choose annual or six-month payment. The MOT for a bike has its own timing, so check both dates. Confirm the current rates on GOV.UK.

Is car tax going up in April?

Rates are usually reviewed each year and changes commonly start in April, but whether a particular rate rises depends on government decisions, which may be announced in a budget. Until a change is confirmed and dated, treat it as a proposal. Check GOV.UK for the current rates and the rules for your vehicle.

What happens if I forget to tax my car?

The DVLA can issue a penalty, and an untaxed vehicle on the road can be clamped or removed. You may also lose the ability to drive it legally until it is taxed. If you have forgotten, tax it straight away online and keep it off the road until then. Amounts are on GOV.UK.

How do I know if my car is taxed?

Enter the registration into the DVLA vehicle enquiry service, or use a free vehicle check that draws on DVLA records. It shows the tax status and due date. Since the paper tax disc was abolished, there is nothing in the windscreen to look at, so an online check is the quickest way to confirm.

Do I pay road tax on an electric car?

This has been changing. For years zero emission cars paid nothing, but policy has moved and the rules depend on the registration date. Do not assume the vehicle is free of tax. Check the current position on GOV.UK using your registration number before you buy or renew.

Is vehicle tax the same in Northern Ireland?

Vehicle tax is generally administered through the DVLA across the UK, but testing differs: the MOT in Northern Ireland is run by the DVA, not the DVSA. If you live in or move to Northern Ireland, check the official guidance for your circumstances and update your address with the DVLA.

Can I tax a van the same way?

Yes, the online service covers vans as well as cars, but the rate depends on the tax class, for example light goods or car-derived. Check the class on the record. For a company van, the registered keeper is responsible for the renewal, so fleet managers often keep a calendar of due dates.

Can I tax a vehicle before the current tax runs out?

Yes. You can normally renew shortly before the existing tax ends and the new period usually runs on from the old one, so you do not lose time. Do it in good time rather than on the last day, in case the payment, the MOT or the insurance record needs attention. The exact window is set out on GOV.UK.

What should I do if the online service will not accept my details?

Check the registration and reference for typing errors, then check that the vehicle is insured, has a valid MOT if needed, and that the keeper details are current. If the record still looks wrong, contact the DVLA rather than trying an unofficial website. A recent change of keeper or a very recent registration can also delay the record updating for a short time.

Official Sources

Rules, fees and deadlines change. Confirm anything that affects your money or legal position with the official service.
