Women are more likely to send their tax return in on time, a study by HM Revenue and Customs (HMRC) has revealed.

For every 10,000 tax returns filed last year from men, 394 were after the deadline, compared to 358 late returns for every 10,000 women.

The demographic with the most late returns, however, was those aged 18-20, with 1,085 in every 10,000 filing late. Perhaps unsurprisingly, those over the age of 65 were the most punctual filers, with only 155 out of every 10,000 missing the deadline. Therefore, the older you are, the more likely you are to send in your tax return on time, HMRC found.

HMRC women and men

HMRC Director General of Personal Tax, Ruth Owen, said:

“Whatever your gender, age, occupation or location, if you haven’t sent in your 2013-14 tax return, you need to take action now.

“HMRC offers a range of help and advice. But don’t leave it until the last minute to contact us. Do it now, and avoid a last-minute rush to beat the deadline.”

Location also has an impact on punctuality. According to the study, those living in the south west were the least likely to miss the deadline, with 299 out of 10,000 filing late. The worst performing region by some distance was London, with 512 late filers. The UK as a whole had 372 late filers per 10,000.

The penalty for missing the Self Assessment deadline is £100 if your return is up to three months late. This will then increase the longer you wait.

The deadline for paper submissions is 31st October and 31st January for online. Check out our nifty guide to completing your Self Assessment for more information. File early to ensure you don’t contribute to HMRC’s big bad list of penalties.
