Cheapest Cars to Tax in the UK (2026): Complete Guide

Road tax, officially called Vehicle Excise Duty (VED), is one of the unavoidable costs of car ownership. Yet many drivers pay far more than they need to, simply because they did not check the tax band before buying. The difference between the cheapest and most expensive cars to tax can exceed £500 per year, and over a five-year ownership period that adds up to a significant sum. This guide breaks down exactly how UK road tax works in 2026, which cars qualify for the lowest VED, and how to use tax costs as part of your buying decision.

Updated 28 October 2026. Budget 2026 raises car tax in line with RPI inflation from 1 April 2027, and HMRC has published the new rates. The standard rate for cars first registered from 1 April 2017 goes from £200 to £210 a year, and electric cars still pay £10 in their first year. For cars registered between 1 March 2001 and 31 March 2017, bands A and B stay at £20 and band C at £35, so the cheapest cars to tax stay just as cheap; band D rises from £170 to £180, band E from £200 to £210 and band M from £790 to £825. Cars registered before March 2001 go to £240 (up to 1549cc) or £390. The figures below are the rates that apply until 31 March 2027. Every 2027-28 rate, plus fuel duty and pay-per-mile tax for electric cars from April 2028, is in our Budget 2026 guide for drivers.

The UK road tax system splits into two main regimes depending on when your car was first registered.

Cars registered between 1 March 2001 and 31 March 2017: These are taxed purely on CO2 emissions. Fully electric cars and anything emitting up to 110 g/km pay £20 per year (Bands A and B), and 111 to 120 g/km costs £35. The bands then climb steeply: 131 to 140 g/km costs £200 per year, 141 to 150 g/km costs £225, and anything above 255 g/km (if registered from 23 March 2006) is charged £790 per year. This system rewards genuinely low-emission vehicles and means that many older hybrids and efficient small cars are extremely cheap to tax. (Cars registered before March 2001 are taxed on engine size instead: £230 a year up to 1549cc, and £375 above that.)

Cars registered on or after 1 April 2017: First-year tax is still based on CO2 emissions, but from year two onwards, cars pay a flat standard rate of £200 per year, whether they run on petrol, diesel, hybrid, or electric power. Electric cars were exempt until April 2025 but now pay the standard rate too. The one addition is the expensive car supplement: cars with a list price over £40,000 (over £50,000 for electric cars) pay an extra £440 a year for five years on top of the standard rate.

Electric vehicles (EVs) lost their road tax exemption on 1 April 2025, so no electric car is tax-free any more. A used EV first registered between April 2017 and March 2025, such as a Nissan Leaf, Tesla Model 3, Renault Zoe, MG4, or Volkswagen ID.3, now pays the standard rate of £200 a year. An older EV first registered before April 2017 pays £20 a year (Band A).

EVs registered from 1 April 2025 pay a first-year rate of £10, then the standard £200 a year from year two. That is the same as a petrol or diesel car of the same age, so the "free tax" advantage that made early EV ownership so appealing has gone.

The expensive car supplement works slightly differently for EVs. An electric car registered from 1 April 2025 with a list price over £50,000 pays the extra £440 a year, so a model like the BMW iX or Mercedes EQS would cost £640 a year (£200 plus £440) for five years from its second tax payment. Zero-emission cars registered before 1 April 2025 do not pay the supplement.

Diesel cars generally produce more NOx and particulates than petrol equivalents, but many older diesels have impressively low CO2 figures that translate to cheap road tax under the pre-2017 system. Diesel models registered from April 2018 also face a first-year tax surcharge if they do not meet the RDE2 emissions standard, but this only affects the first year.

If you are buying a post-2017 diesel, the flat rate of £200 per year applies from year two, the same as petrol. The real savings with modern diesel come from fuel economy on high-mileage journeys rather than from tax advantages.

Hybrids sit in a sweet spot for road tax, especially older models registered before April 2017. The Toyota Prius, Hyundai Ioniq Hybrid, and Kia Niro Hybrid all produce CO2 figures in the 70 to 99 g/km range, putting them in VED Band A, which means annual tax of £20.

Plug-in hybrids (PHEVs) registered before April 2017 with CO2 emissions of up to 100 g/km also pay £20 a year (Band A). Post-2017 PHEVs pay the standard £200 from year two, but their lower first-year rate (£115 for 1 to 50 g/km) provides a small initial saving. Just be aware that PHEVs with a high list price will trigger the expensive car supplement.

For the best combination of low tax and low fuel costs, a pre-2017 full hybrid remains one of the smartest choices on the used market.

Any car with a list price (including options) exceeding £40,000 when new attracts an additional VED supplement of £440 per year for the first five years of standard-rate tax. For electric cars registered from 1 April 2025 the threshold is £50,000, and zero-emission cars registered before then do not pay it. This means you could be paying £640 per year in road tax alone. Models commonly caught by this rule include:

• BMW 3 Series (most variants)
• Mercedes C-Class and above
• Audi A4 and above
• Volvo XC40 and above
• Land Rover Discovery Sport

If you are buying used and want to avoid this surcharge, check whether the original list price was under £40,000 (£50,000 for an electric car registered from April 2025). The supplement only applies for five years from the date the standard rate first applies (usually from year two), so a six or seven year old premium car may have passed out of the supplement period entirely.

Road tax is only one part of the picture. A car with £20 VED but poor fuel economy and high repair bills will cost you more overall than a reliable, efficient car that pays £200 in tax. When comparing cars, always consider the total annual running cost, which includes fuel, road tax, MOT, insurance, and predicted repairs.

Our cheapest cars to run rankings factor in all of these costs using real MOT data. You might find that a car paying £20 in road tax with a strong MOT record is significantly cheaper overall than a car with low fuel costs but expensive tyre and brake replacements.

There are several ways to find out what VED band your car falls into:

1. CarCostCheck: Enter any registration on our site and we will show you the current tax status, annual tax cost, and due date as part of our free vehicle report.
2. DVLA Vehicle Enquiry: The government's official tool at gov.uk lets you check tax status by registration.
3. V5C logbook: Your V5C document lists the CO2 emissions figure, which you can cross-reference with the VED band table.

If you are shopping for a used car, always check the tax band before making an offer. It is one of the easiest ways to avoid an unexpected annual bill. Visit our road tax calculator for a quick lookup.

Here are practical strategies to keep your VED bill as low as possible:

• Buy a pre-April 2017 low-emission car. The CO2-based system rewards efficient vehicles with very low tax, from £20 a year.
• Consider an older EV. An electric car first registered before April 2017 pays just £20 a year, and electricity is cheap compared with petrol if you charge at home.
• Avoid the £40,000 threshold. If you are looking at a premium model, check whether a lower-spec version falls under the £40,000 list price (£50,000 for an electric car registered from April 2025) to dodge the five-year supplement.
• Check total running costs, not just tax. A car with slightly higher VED but better fuel economy and reliability may save you more overall. See our full running cost rankings for data-backed comparisons.
• Pay annually. Paying the full year in one go is cheapest. Twelve monthly Direct Debits cost 5% more in total (£210 instead of £200 at the standard rate), and a single six-month payment costs 10% more than half the annual rate (£110 instead of £100), or 5% more (£105) by Direct Debit.
