Description

Self Assessment is a system HM Revenue and Customs (HMRC) uses to collect Income Tax.
Tax is usually deducted automatically from wages, pensions, and savings. People and businesses with other income must report it in a tax return.
This is a short guide to assist you in preparing your own UK self-assessment tax return. It is written from the viewpoint of an accountant, so it contains some tips and common mistakes.
This is designed for someone with fairly simple tax affairs who wants to prepare their own tax return rather than hiring an accountant. Updated for changes to tax law relevant to the 5 April 2019 tax year.
