Annual Investment Allowance (AIA)
Tax relief on the full cost of equipment in the year you buy it.
Instead of claiming the cost of a laptop, van or tools gradually over several years, the AIA lets most businesses deduct the full amount in the year of purchase, up to £1 million a year.
Cars are excluded; they have their own capital allowance rules.
