Self Employed Tax Return Guide 2020/21

Updated: Apr 19, 2020




This article is the latest summary of tax rates and other key changes affecting the self employed in the new tax year starting from 06 April 2020.


Any person working for him or herself in the business is classed as self-employed or sole trader and is required to file a self assessment. Self employment is an unincorporated form of business which does not require company registration with Companies House.


Business Registration

You should register with HMRC for self assessment as a self employed business. Registration for self employment is compulsory for all self employed individuals even if you are an existing tax return filer.


Business Records and Accounting

As a self employed business person, you would record your income and business expenses for accounting purposes. Allowable business expenses may include cost of sales (purchases), office rent, travel costs, admin such as printing, marketing, telephone and internet. Each business is unique and so are its expenses. File Digital can help you assess which business expenses can be claimed in your Annual Accounts to minimise the tax liability.


Accounts and Self Assessment

Self Employment accounts are usually prepared for the same period as tax year i.e 6th April to 5th April every year. Current tax year is 2020/21 starting from 6th April 2020 and ending on 5th April 2021. As a self employed business, you are required to complete a self assessment for each tax year. Depending on the nature of your business, you may be required to complete different sections of self assessment tax return.


All sole traders fill in the main section of self-assessment (SA100) and provide additional information on supplementary pages such as SA102 for employment, and SA105 for property. The main section SA100 can be filled in using the figures calculated in your Annual Accounts. Primarily, it requires figures for sales, business expenses and capital expenditure.


Short Self Assessment

HMRC allows self employed businesses with profits under the compulsory VAT registration threshold to submit a shorter version of Self Assessment. SA103S can be filled in with the total of your sales and expenses figures in respective boxes instead of the full breakdown of expenses under relevant categories.



Tax Liability

Tax liability on your self employment profits are calculated after deducting the personal allowance. Current personal allowance for 2020/21 or PA is set as £12,500.
