Hiya - I wonder if anyone can help me work this one out. I have a discrepancy between the amount of gross pay I earnt this tax year and the taxable pay showing on my payslip. It doesn't show an accrued gross total, but I've worked out what the difference is. I thought that the difference would be due to pension, as pension is non-taxable (is that correct?) But the figures are about £40 different. Could that be because more pension was taken since January and the system is still programmed in for 6% to be non taxable? I need to notify the tax credits people what my salary was - what figure do I give? the taxable amount shown on my payslip or my actual gross amount? Please help!
