Tax Code change, whats OT?

[andy-xr]

For the last few years I had a tax code that was 3 numbers and a letter, I think it was 737L? I just got a letter through from HMRC (dated mid Feb) that says my tax code is now OT

I was made redundant last year and started a new job. Somewhere along the way I lost my P45, but completed a P46 form. Is this related does anyone know, or are we all being changed somewhere along the line?

It is, 12/13 notification

Still not sure why somethings changed, on hold to HMRC now to see if I can find out. Thanks for the help!

OK, seems HMRC made an error on one count (assumption of benefits) and underpayment of tax back in 2008-09 has left me owing. There was something about a section 336 as well, but I'm going to call the 3rd party payment company who dealt with everything at that time and see if they have any records or could write to HMRC for me

Thanks for the help!

No suck luck!!

I have to send them some P11D's and a couple of Section 336's - they'd factored in some healthcare benefits which was fair enough
