Women are better at filing their tax returns than men, HM Revenue and Customs (HMRC) has revealed.
Members of the fairer sex are more likely to file on time and avoid penalties for late payment, which start at £100 but can climb to £1,000 if still not filed and unpaid after six months.
For every 10,000 paper and online tax returns received last year by the revenue, only 358 arrived late from ladies, compared to 394 from men.
Irrespective of gender, taxpayers aged 18 to 20 were the least punctual with 1,085 returns filed late out of every 10,000 returns completed. Over-65s were the best at abiding by the deadlines, with only 155 out of every 10,000 filing late.
Workers in the information and communication industries, meanwhile, were the worst professionals for filing late, with 390 tardy returns per 10,000 filed. Builders followed closely behind at 352.
The most punctual workers were those in the agriculture, fishing and forestry industry with just 109 but lawyers and the tax experts themselves, accountants, could only muster second plate with 219 late filers per 10,000.
Scottish taxpayers were the worst of all UK residents for filing returns late at 391 per 10,000. The English were the next latest with 374, followed by the Welsh (346) but the Northern Irish came out on top with only 301 late returns per 10,000 submitted.
Ruth Owen, HMRC's director general of personal tax, said: "You must file your 2013-14 tax return, and pay what you owe, by midnight on 31 January. If you haven't yet registered for HMRC Online Services, you need to act now, as it involves HMRC posting you an Activation Code and this can take up to 10 days to arrive."
