Self Assessment Tax Return

HMRC sends Tax Returns or a notice to collect tax return to everyone in the Self-Assessment system in April of every tax year. Self-assessment is short for the 'Self-Assessment tax return', and is a system of HMRC (HM Revenue and Customs) in the UK for many businesses to collect Income Tax. It covers most income earned in the same year and must be filed with HMRC.

The term Self-Assessment tax return is usually just know as a tax return. But company or businesses are not the only people who are required to complete a self-assessment return. You all need to fill in a tax return if:

  • You are self-employed/freelancer, a business partner, sole trader or director of a limited company.
  • You are an employee or pensioner with an annual income of £100,000 or more.
  • You are earning £100,000 or more before tax from saving or investment.
  • You received a P800 form from HMRC saying you didn't pay enough tax last year - and you didn't pay what you owe
  • You are a trustee or representative or received income of someone who has died.

Self-assessment form

Self-Assessment deadlines:

  • The deadline for paper tax returns midnight 31 October 2018
  • The deadline for online tax returns midnight 31 January 2019
  • The deadline for pay the tax you owe midnight 31 January 2019

In case if you fail to meet the deadline you may have to pay a penalty for the same for HRMC.

If you receive a tax return notice to file on line, you must complete a tax return form and submit it to HMRC. If any of these apply, this will usually ask you to fill in a tax return. But if you know you need to submit a self-assessment tax return, you should not rely on HMRC to contact you. The contact number for self-assessment is 0300 200 3310 for all type of enquires. For more help with your Self-Assessment tax return, you can contact to HMRC for any further guides.
