If you're self-employed there are various deductions, reliefs and allowances that you can get to reduce your tax bill.
You can deduct much of your business expenditure to work out your profits - but you can't deduct any private expenditure. And you can claim special reliefs for certain 'capital expenditure' - one-off expenditure to buy or improve an asset you keep and use for your business.
You can usually get deductions, reliefs and allowances for the current tax year and for the previous four years - but there are some where you have a shorter time limit for claiming.
This guide tells you about the tax allowances, deductions and reliefs you can get as a self-employed business person.

While you're running your business you're likely to spend money on different sorts of things. Your expenditure will usually fall into three different types:
The type of expenditure it is affects whether - and how - you can get tax relief for it.
Expenditure on buying, creating or improving a business asset that you keep to earn the profits of your business is capital expenditure. So, the cost of buying a van for your business is capital expenditure but the cost of hiring it isn't.
Other examples of capital expenditure include the cost of buying business premises, machinery, computers, fixtures and furniture.
You won't be able to get tax relief for all types of capital expenditure. And if you can, there are special rules for how you can claim it.
You can get tax relief for your business expenditure as long as it's not:

You can get some private benefit from the expenditure and still get tax relief for the amount spent for your business, as long as either:
You can deduct the full amount of your allowable business expenditure from your business income to work out your taxable profits.
This guide provides further information on the difference between 'allowable and non-allowable expenses' below.
Private expenditure is what you spend on your day-to-day living expenses and your normal household expenses. It includes the amounts you take from your business as a wage - your 'drawings'.
It also includes the private part of any expenditure that's for both business and private purposes.
Private expenditure is non-allowable expenditure - you can't get tax relief for it.
A business expense is allowable if it:
The most common expenses that are normally allowable include:
Expenditure for a mixed private and business purpose is non-allowable expenditure. An example would be the cost of travelling to town to bank the business takings and do your private shopping at the same time.
If you can separate the expenditure between business and private purposes, the business part is allowable. So, if you use a car separately for business and private purposes, the proportion of the expenses that relates to:
You normally work out the allowable business and non-allowable private proportions based on the mileage covered for each.
