Why has income tax gone up in December 2012 - Gross pay, NI, tax code all stayed the same?
Month 1 or cumulative tax code?
Was the tax code previously operated on a Month 1 basis - indicated on the payslip as M1 or X or * after the number - and has now been changed onto the cumulative basis? If so, pay and tax from a previous employment in this tax year may have been included. You can check this by adding the December gross pay and tax figures to the YTD figures on the November payslip and see if they agree with the YTD figures on the December payslip.
Thanks - no previous employment in this tax year and cumulative tax code for 2012-13.
Has the tax code changed at all within 12-13?
How much has the tax gone up by?
Thanks - no change to tax code in 12-13 - tax gone up by approx £450.
Shot in the dark
Were you unemployed at the start of the tax year ?
Or have you had a pay rise ?
Thanks - not unemployed and no pay rise.

I think you need to have a chat with your salaries dept. I've run out of ideas.
