What can I claim in my self-assessment
tax return?

GoSimpleTax Income/Expenses

You may have been told that you’ll be able to claim back certain elements of expenditure when completing a self assessment tax return, but it’s hard to know what is hearsay and what actually constitutes a “business expense”. See below for the costs you will be able to cover via a HMRC expenses claim – you may be aware of some, but others might just come as a pleasant surprise.


Whether you drive a vehicle or use public transport to get to meetings or you place of business, you should keep your tickets and receipts for everything – including fuel, parking, repairs and insurance – as these are allowable expenses if you’re self-employed.


Salaries and wages can be claimed on expenses, as can bonuses, pensions, National Insurance and other staff costs. You shouldn’t claim for carers or nannies, however.


Your allowable premises-based expenses are made up of the costs of items or services that will last for less than two years. These include stationery, rent, insurance, heating and lighting (this is also applicable to those who work from home – take a look at how to calculate your utilities expenses here).

Legal and Financial

If your business uses accountants, solicitors, surveyors or architects, you can claim their fees back on expenses. You can also claim for professional indemnity insurance premiums. However, the legal costs of buying property and machinery and fines for breaking the law are not considered tax deductible expenses.


If your business requires you to purchase particular items of clothing, such as uniforms, costumes or protective garments, these can all be submitted to HMRC as expenses. You cannot claim for clothing that is not specific to the work you do.

Marketing, Subscriptions and Entertainment

You can also claim back for subscriptions to magazines that expand your specialist knowledge (though no politically oriented publications are permitted), along with the costs of bulk mail advertising, free samples and website costs if they are for use by your business.
