Claiming equipment: capital allowances and the Annual Investment Allowance

Updated 27 June 2026
The short answer

When your company buys equipment it keeps and uses, like a laptop, tools or machinery, you usually take the full cost off your profit in the same year, so it cuts your Corporation Tax straight away. This relief is called the Annual Investment Allowance, and it covers up to £1 million of equipment a year. Cars are the main thing it leaves out, and they follow their own rules: a brand-new electric car still gets the full cost off in year one, while other cars get a slower year-by-year relief.

Why equipment isn't just a normal expense

Most costs your company pays, like stock, wages or your phone bill, come straight off your profit the moment you spend the money. Equipment is different. When you buy something you'll keep and use for years, that's a capital cost. Think of a laptop, a drill, a coffee machine or a desk. The tax rules give you relief for it through something called capital allowances instead of treating it as an everyday bill.

That sounds like extra work, but for almost every small company it ends the same way: the money you spent comes off your profit, so you pay less tax. It just travels through a different door.

What is the Annual Investment Allowance?

The Annual Investment Allowance is the door most of your equipment goes through. It lets you take the whole cost of qualifying equipment off your profit in the year you buy it, up to £1 million of equipment a year.

A £1 million yearly limit is far more than a typical small company spends on kit, so in practice you get all of it back against your profit, in one go, the same year. You don't have to drip the cost out over several years.

A real example: buying a £2,000 laptop

Say your company buys a £2,000 laptop this year to do the work.

  • The full £2,000 comes off your profit this year through the Annual Investment Allowance.
  • If your profit before the laptop was £20,000, it's now £18,000.
  • You only pay Corporation Tax on the £18,000.

So the laptop cuts your tax the same year you bought it, just like a normal cost would. The same goes for a £500 set of tools, a £4,000 machine, or £900 of office furniture.

What counts as "equipment" for this?

The kind of equipment that goes through the Annual Investment Allowance is the stuff you buy to keep and use in the business:

  • Computers and tech: laptops, monitors, printers, phones you keep.
  • Tools: anything from hand tools to a workshop full of kit.
  • Machinery: the equipment that makes or does the thing you sell.
  • Office furniture: desks, chairs, shelving, storage.
  • Vans and lorries: a van counts as equipment here (a car does not, more on that below).

If you bought it to use it, not to sell it on, and you'll have it for a while, it usually goes through this allowance.

Cars are the big exception

A car is the one thing the Annual Investment Allowance leaves out. But there are two very different outcomes, and which one you get depends on the car. This is the bit that costs people money if they get it wrong, so it's worth a careful read.

A brand-new, fully electric car (zero emissions): you get the whole cost off your profit in the year you buy it, just like a laptop. This is a special 100% first-year allowance. It only counts when the car is new and unused: buy the same electric car second-hand and you don't get it. So a director buying a new EV through the company gets the full deduction straight away.

Any other car (petrol, diesel, hybrid, or a second-hand electric one): the relief comes slowly, spread over several years, not all at once. How fast you get it depends on how much CO2 the car gives off. Cleaner cars get the relief quicker.

A van is not treated as a car for this. A van still goes through the normal equipment allowance and gets the full amount in the year you buy it. If you're buying any kind of vehicle, this is the bit worth getting right, and we sort which rule applies for you.

Depreciation vs capital allowances (two words for a similar idea)

You might see the word "depreciation" in your accounts. It means spreading an asset's cost over the years it lasts, a way of showing the kit slowly wearing out. That's the accounts version.

For tax, we ignore depreciation, we add it back, and use capital allowances instead. They're the tax world's version of the same idea. You don't pick between them or work out the swap. We handle that part so the right figure lands in the right place.

Do I have to keep the receipt?

Yes. Keep a record of what you bought, the date, and what you paid, and hang onto it for six years from the end of the accounting period it falls in. If HMRC ever asks, you can show the equipment was real and the allowance was right.

How SimpleReturns handles it

Connect your bank or upload a statement, and we spot the equipment you bought, apply the Annual Investment Allowance, and take the right amount off your profit. If you've bought a car, we pick the right rule for it: a new electric car gets its full cost off in year one, while other cars go on the slower year-by-year track. You see every figure before anything is sent, and you never have to work out which allowance or which box anything goes in.


Common questions

Can my company claim the full cost of a laptop in one year?

Yes. A laptop is equipment you keep, so for almost every small company the full cost comes off your profit in the year you buy it, through the Annual Investment Allowance.

How much equipment can I claim in a year?

Up to £1 million of qualifying equipment a year through the Annual Investment Allowance, far more than a typical small company spends, so in practice you get all of it against your profit.

Does buying a machine cut my Corporation Tax?

Yes. Most machinery and tools come off your profit in the year you buy them, so your tax that year goes down by the tax on that amount.

Why can't I claim a car the same way?

It depends on the car. A brand-new, fully electric car (zero emissions) does get its full cost off your profit in the year you buy it, through a special 100% first-year allowance, as long as it is new and unused. Every other car (petrol, diesel, hybrid, or a second-hand electric one) is left out of the Annual Investment Allowance, so its relief is spread over several years and the speed depends on how much CO2 it gives off. A van, though, counts as equipment and gets the full amount in the year you buy it.

What's the difference between depreciation and capital allowances?

Depreciation is the accounts way of spreading an asset's cost over its life. Capital allowances are the tax way of doing the same thing. For tax we use capital allowances and add depreciation back, and we handle that swap for you.

Do I need to keep the receipt for equipment?

Yes. Keep what you bought, the date and what you paid for six years from the end of the accounting period, so you can back up the allowance if asked.

Ready to do it the easy way?

You don't need to know any of the above to file. We read your year's money in and out, spot the equipment you bought, work out the allowance, and show you every figure before anything is sent, for £99, once, no subscription.

Or, if your company is more complex, like buying several cars or big assets across group companies, an accountant may be the better fit, and that's an honest call to make.
