Navigate Your Taxes with Ease—Let Swift Accountants Lead the Way!

A Self Assessment Tax Return is a system used by HM Revenue and Customs (HMRC) to collect Income Tax from individuals and businesses whose income isn't taxed at source.

While most employees have their taxes deducted automatically through Pay As You Earn (PAYE), many others receive income from sources where tax isn't automatically deducted.
If this applies to you, you're required to report this income through a Self Assessment Tax Return.
