Those running a business and making up accounts to 5 April should consider buying plant and machinery to take advantage of the Annual Investment Allowance (AIA) of £200,000. The AIA provides a 100% tax write off for equipment used in your business. This tax relief extends to fixtures and fittings within business premises such as electrical, water and heating systems. There is also 100% tax relief if you buy a new car that emits no more than 95g CO2 per kilometer and an increasing number of cars now fall below that limit.
Note that 5 April is not relevant if your business makes up accounts to a date other than 5 April. If your business year end is say 30 June, then you would need to acquire the equipment before that date to get the 100% tax relief.
