If you include all taxes such as VAT then virtually every individual in the UK is a taxpayer, though thankfully not everyone has to file a tax return. Approximately 9.5 million tax returns are issued each year by HM Revenue & Customs and these must be completed and submitted by 31 October if completed on paper, or by 31 January if completed online.

31 January is also the deadline for payment of any tax due as a result. Fixed penalties and surcharges apply to those who file their returns late or fail to pay their tax on time. It is therefore important to be aware of our responsibilities for reporting our income and chargeable gains and for filing a tax return.

The majority of employees have their income tax deducted at source by their employer through the Pay As You Earn system and have no additional liability to tax each year. They are not generally required to fill in tax returns. It is also no longer an automatic requirement for the UK's 4 million higher-rate taxpayers to complete a return either, although many will still be required to do so for other reasons. On the other hand, most individuals who are self-employed, either alone or in partnership, will need to file an annual tax return.

Finally, you must not rely on HMRC to know all about your personal tax affairs. Just because they have not sent you a tax return for example, does not mean that you have no requirement to complete one. Our useful guide, should help you decide whether you have anything to declare and we can help you get your tax returns in order, even if you have not done so for a number of years and have back tax to pay.
