Capital allowances are rates set by HMRC that self-employed business owners must use to claim tax relief on fixed assets.
So if you have purchased an asset for your business, then this is how you can claim tax relief on your self-assessment tax return form.

Why Did HMRC Introduce Capital Allowances
When you buy a piece of equipment, like a laptop, you pay for it up front and then use it for a few years.
So if you pay £1,500 the laptop and plan to use the computer for 3 years, then ideally you would claim £500 as an expense against your taxes for 3 years.
What this meant was businesses reduced the number of years they said they were going to use equipment to accelerate their claim against their taxes.
To equalise things, HMRC has rules for tax (not accounting) purposes, these are Capital Allowances. These rules set out percentage tax relief a business can claim each year, depending on what they have bought.

The Annual Investment Allowance for 2019/2020 is £1m.
That means businesses can claim 100% tax relief on fixed assets that meets the AIA criteria in the year they bought it.
