Income Tax and National Insurance paid to 31 October 2017

Your taxable pay between 31 July 2017 and 31 October 2017 is £12,500.01.

Using the figures supplied by your employer we estimate your annual taxable income from them will be £33,467.

Also - yes, the amounts relating to previous employers appear correct.

Any pointers?

These figures show that you have now been paid for October - can you say how much tax you have paid in October?

From the previous posts, it is clear that you have moved from 1150L non cumulative to 1150L cumulative. This only normally happens for 2 reasons:

1. HMRC has given your employer a new tax code. To make it cumulative, they should also have told your employer your previous gross pay and tax. It may be that it is a mistake by HMRC or your payroll people have not entered the previous amounts.
2. You have given your payroll people your P45 and they have used the correct code but forgotten to also pick up your previous pay and tax details.

Check these two options first, and if it is not a payroll mistake, phone HMRC. They should be able to put you on a non-cumulative code that will recover the undepayment over the rest of the tax year, rather than take it in a lump. In theory, with the new 'dynamic tax code system' HMRC should do this themselves eventually, but you could phone them to give them a nudge!
