With just a week to go before the self assessment deadline almost a third of those required to file their tax return have yet to do so, according to HMRC.

As of Wednesday, around eight million people nationally have filed their self assessment for 2016/17 – but just over three million people are yet to complete their returns.

People in East Anglia have also been cutting it fine – as of January 5, 44% of those who needed to complete a self assessment in Norfolk and Suffolk had not done do.

In Essex the figure was 46% and in Cambridgeshire 47%.

HMRC is reminding customers that sending in a tax return late will incur a £100 penalty – even if you do not owe any tax.

Angela MacDonald, HMRC director general of customer services, said: 'The seven day countdown to January 31 has now begun. Put a stop to that niggling feeling and do your self assessment now.'

Help is available at www.gov.uk/selfassessment or from the self assessment helpline on 0300 200 3310.

Last week HMRC published some of the strange excuses and expenses included in British workers' tax returns.
