Online Tax Return

HM Revenue and Customers operate a free online tax return service at https://online.hmrc.gov.uk/.

This service allows you to complete your tax return online, validate your information, calculate your tax liability, view your tax return, and file over the Internet.

This service supports:

• the main tax return form (SA100)
• the employment form (SA101)
• the share schemes form (SA102)
• the self employment form (SA103)
• the partnership form (SA104)
• and the land and property form (SA105).

If you need to complete other tax return forms or have complex tax affairs, we recommend you find a UK tax adviser.
