Tax relief calculations (updated)

It was brought to my attention that the tax relief calculator I created last year was no longer available. So, with the 2013 self assessment deadline nearly upon us I spent a couple of hours rebuilding and reskinning the tool.

The premise of the tool is simple, input your monthly working from home expenditure and then outline the monthly use of your home – the result should be the amount you can claim back as a working from home allowance.

The tool is up at a new URL: and I welcome any feedback
