Self-employed people have to file their tax returns by Sunday (31 January). Her Majesty's Revenue and Customs (HMRC) is trying to get everyone to fill in the online forms as early as possible to prevent technical problems from standing in the way.

Those who have to fill out self-assessment forms (you can check here if you should) can claim expenses for their business on which they will receive tax relief. As HMRC is trying to get the word out so that people who have to fill out their self assessment reach the deadline, it has listed the weirdest claims people have made.

"There are a number of items and expenses that people can claim against, such as genuine business costs and items needed to do a job," Ruth Owen, HMRC director of personal tax said in a statement. "But a painful beauty regime or the furniture for your own home are not items that every taxpayer in the country should be contributing towards."

On a more serious note, HMRC said that it is wrong that a small minority of self-employed try to get the "honest majority" to subsidise other people's products and services if they don't need it for their business. "HMRC will never allow for these to be processed as genuine claims."

"It's best to complete your tax return sooner rather than later. Our online service is quick and simple to use, with lots of helpful information – completing your tax return is easier than you think," Owen added.

Below, the craziest claims are listed, as provided by HMRC

  • The costs for storing Mars Bars overnight in a fridge
  • The cost of a pair of flip flops so I don't have to walk barefoot between my work's changing and shower rooms
  • The costs for my intimate waxing
  • I bought a second-hand car to get me from home to work so I didn't have to walk
  • I purchased my own flat, so I need to claim back the money I spent on the furniture.
