Owe HMRC underpaid income tax, wrong date on previous employer's P45

Dazed_and_C0nfused

If the underpayment of tax arose from either one of my employers (which is increasingly likely to be the case) or HMRC themselves making an error, then I will at least have some form of relief. I would understand if it was due to an error on my end somewhere down the line, but that is why I want to be 110% certain before making any decisions.

What "relief" do you expect to be able to get?

The calculation is for the previous tax year so HMRC are notifying you within their normal timescales, not late at all.

AskAsk has summed it up concisely really.

Unfortunately, You have no case and need to pay the tax.  HMRC may adjust your tax code for the new tax year and you'll pay it back that way.

Have just seen your post of 11.31 this appears to be far more than an overlap of tax months.  In order for your second employer to have made a tax rebate of this magnitude they must have received previous pay and tax details. To understand what has happened more details are required.
As I understand it there were three employments ( and I assume no periods of unemployment benefit) 
First employment tax code and was there an X after it along with gross and tax figures.
From second employment which had three payslips from each payslip taxable gross, tax paid/refunded, tax code, taxable pay to date and tax paid to date.  Also if showing previous gross and tax figures.
From third employment last payslip for the tax year taxable gross, tax paid/refunded, tax code, taxable pay this employment, tax paid this employment,taxable pay to date and tax paid to date.  Also if showing previous gross and tax figures.

Thank you, I'm working on getting this information now.

So from the responses in this thread I'm guessing it's safe to say one of my employers definitely made an error - would this be enough on its own to raise a query with HMRC? Would there also be anything worth contacting my employers about to help my case?

Happy to look at the figures and see if I can explain what has happened but cannot say if the information will help in reducing the tax owed.

Gather all your P45s and your P60 for the year in question. 

Add up your gross income. 

Add up how much tax you have paid. 

now go to a site like https://listentotaxman.com/ and enter the details there. 

If the results there show that you have underpaid tax, you have underpaid tax and need to repay it. You can worry about how it happened if it makes you feel better, but you'll still need to repay the tax.

The following link relates to errors by employers in deducting tax.  Showing that the employer "...did not take reasonable care to operate PAYE and the error was not made in ‘good faith’." would I suspect be difficult to prove, assuming that it was an error by the employer.
