HM Revenue & Customs (HMRC) has issued an alert to anyone filing their Self Assessment tax return on paper — get it in by 31 October, or you could face a £100 penalty.

If you normally file on paper, you could also file your return online instead. It’s simple to file your return electronically — three quarters of Self Assessment filers already do it — and you get three months longer to file.

Online filing has other advantages too: your tax is calculated automatically; you get an immediate online acknowledgement once you’ve filed; and it’s processed faster, so any money you’re owed is repaid more quickly.

Registering for online filing is simple — visit the HMRC website at and click “Register for Self Assessment Online”.

Help and advice is available from the HMRC website at or from the Self Assessment helpline on 0845 9000 444.
