Generally, individuals who work for an employer pay their tax through pay as you earn (PAYE). Occasionally, for the more highly paid individuals, with income over £100,000, HMRC may request that they complete a self-assessment, as a means of a catch-all for tax at the end of each tax year.

Where individuals have additional sources of income, outside of PAYE, they may be required to complete a self-assessment if one or more of the following apply to you:

• You are working for yourself as a self-employed individual.
• You run your business together with others as a share in. a partnership.
• You are a trustee or the executor of an estate, on behalf of your beneficiary.
• You receive dividends from a company in excess of £1,000.
