The Annual Investment Allowance (AIA) provides businesses with 100% tax relief, in the year of purchase, for many business assets. Qualifying assets include plant and equipment, machines and tools, vans, lorries and diggers (although it does not apply to cars).
The AIA was previously £200,000, but will be increased significantly to £1,000,000 from 1st January 2019 for a 2 year period, giving businesses an attractive tax incentive to accelerate their capital investment decisions.
