Just been checking payslips to make sure my overtime rate is correct and have been putting the figures into http://www.thesalarycalculator.co.uk for comparison too and it looks like I should be paying more tax 
The website claims last month I should have paid £1291.20 tax - I only paid £1065.
Can someone check that website is correct?? I hope the taxman isn't going to demand a large sum back
