hi all, I wasnt sure which forum to post this in.   I got paid ver the weekend and this morning I got a text from my bank saying i will be overdrawn.   after looking into it my tax code is K1263X and HMRC have taken £1360 tax compared to £823 a month.
I've been on the phone listening to hold music all morning, they are busy with the self assessment I guess. 
I've just been through all my pay slips and noted down the wage, tax per month, tax code etc,  and below are the when the tax codes change.  I do sometimes get a bonus and pay increase each feb/march. 
I do get private medical which is £6383 on my p11 d 
And I have from August 2020 paid more into my pension to reduce my tax bill.  
with the tax codes below for instance 2020 Oct upto and inc Dec pay the tax code is the same at 348L

The accountant at work has covid so is off at the moment and Im concerned now, i will pay the mortgage but will have to cancel direct debits and pay some via credit card for now. Just anyone seen anything like this before or where to start trying to work out what has gone so wrong

well ringing back HMRC has paid off, i ended up waiting another 40 mins but got through.  
it seems the K1263 tax code has been applied to recoup the child benefit we claim,  she has switch that back to paying it back through by self assessment.   but now im not sure if through the tax code is a better way.
and also she said that HMRC was notified in June 2020 that our private medical had increased she said that they sent over electronically new tax codes, mine shoull have been 518L instead of 883L,   she said the system looked in october and realised that the 518code had not been applied, so adjusted the tax code to 348L.  
She had taken off the child benefit and has said my tax code is now 611L which will last upto April 2021 
I asked if i can get the money back now rather than waiting and she said that companies can apply for a tax refund via the portal.
seems a right old mess and now i have to rely this back to the accountant and pay role people at work.   
Has anyone had something similar and how best to deal with it.

Can you wait until February salary when it will be refunded? If you can I would still be ensuring that payroll has received the new code.

I dont think i have another option i will speak to someone at work tomorrow, I can borrow some money from my wife to pay the bills this month but I need to make sure that it comes back in one month rather than drip feed it over the next few months.  I just want to be in a place so i know what my net pay is going to be so i can work out my outgoings etc so i know where i am.

The most important thing you can do now is to check if the tax code has been issued on a cumulative or non cumulative basis.

Cumulative means your tax will be recalculated back to April 2020 with any adjustment made in your next payslip.

Non cumulative means the new tax code will only be used against the next payslip, what happened before will not be looked at on your next payslip.

thankyou, i guess thats HMRC which are the only ones that can confirm that for me,  I will will ring them tomorrow before speaking to the payroll people at my workplace

Sounds sensible, check what HMRC have issued first and then that payroll are implementing it correctly.
