How Old Does a Bike Have to Be to Be Tax Exempt: 40-Year Rule

A motorcycle qualifies for tax exemption in the UK once it was built more than 40 years before 1 January of the current tax year. So from 1 April 2026, any bike constructed before 1 January 1986 sits in the historic vehicle tax class at a £0 rate.¹ The cutoff rolls forward every year, so a fresh batch of bikes ages into eligibility each April.

How the 40-Year Rule Actually Works

The formula lives in Schedule 2 of the Vehicle Excise and Registration Act 1994: a vehicle is exempt during the 12 months starting 1 April if it was constructed more than 40 years before 1 January of that same year.²

What that looks like in practice: a bike built in March 1986 will not become exempt on 1 April 2026, because it was not constructed before 1 January 1986. It becomes exempt on 1 April 2027, when the cutoff moves to 1 January 1987.

Build Date, Not Registration Date

The legal test is when the bike was built, not when it was first registered. That matters, because many bikes sat in warehouses or showrooms for months before someone bought them. If your V5C shows a manufacture date, that date controls.

If you do not know the build date but the bike was registered before 8 January 1986, you still qualify for the exemption from 1 April 2026.¹ The short window between 1 January and 8 January is a buffer for the normal delay between a bike leaving the factory and landing on the register. If the V5C has no clear manufacture date and registration falls after that window, you may need supporting evidence from the manufacturer or a recognised owners’ club to confirm the bike was built before 1 January of the relevant year.

Commercial Use Cancels the Exemption

Age alone does not do it. A bike used for hire or reward, or used commercially in connection with a trade or business, loses its exempt status.¹ The statute defines commercial use as use for hire or reward or for or in connection with a trade or business.²

Paid courier work, deliveries, or using an old bike as a taxi all count. Riding your Bonneville to the office does not; the restriction targets bikes generating revenue through their use as transport. Commuting, weekend rides, and rallies are fine.

You Still Have to Tax It Every Year

Exemption is not automatic when your bike turns 40. You have to apply for it.³ You will need your V5C registration certificate and valid insurance. The change is usually made at a Post Office that handles vehicle tax, timed to when your existing tax is due to expire. DVLA will then send you an updated V5C reflecting the historic vehicle tax class.⁴

And here is the part that catches people out: exempt does not mean you can forget the bike exists as far as DVLA is concerned. The historic vehicle class carries a £0 rate, but you must still renew each year at that nil rate. DVLA uses the annual renewal to keep keeper records current, and the bike will show as “Taxed” on the government’s online checker.

If you let it lapse, even at £0, the bike can be flagged as untaxed. You would then need to renew the nil-rate tax or file a Statutory Off Road Notification (SORN) if it is not being used on public roads. The renewal takes a couple of minutes online or at the Post Office.

MOT Exemption Is a Separate Question

A bike over 40 years old can also be exempt from the annual MOT, but only if it has not been “substantially changed.”³ The tax exemption has no substantial change test of its own. Even if your bike has been modified enough to still need an MOT, it can still sit in the £0 historic tax class based on age alone, as long as it is not used commercially.
