P60 actual or proposed earnings

Hi all,
i am confused. my husband was let go in December but company only paid he and the others til mid Oct (no money to pay anyone). We got our P60's and looked for rebalancing and apparently we owe 440 euro!!!!!!! The thing is his P60 states his earnings as the amount he would have earned if they had paid him til the end of the year not what he actually earned. He had our tax credits too. I was on mat leave last year and took unpaid leave so we had no income for november at all.
I suppose my question is whether or not his p60 is correct? i thought it was what you actually earned. He also didn't get payslips for months and don't think we can do anything about that now. As everyone was let go and the office is unoccupied there is no-one to contact to ask about this. What do ye think?????????????????

A P60 is an official document and it is a statement of your ACTUAL earnings in a given year. You should always insist on a payslip as you could then check that the figures on the P60 are the same as the cumulative figures on your last payslip for that year.

should he not have got a p45 for that year ?
was he made redundant?
was he employed by company or soletrader?
is the company/sole trader still trading

by answering above items, you might get a more accurate answer.

Hi
it was a tempory lay off till jan and then it became permanent. It was a company rather than sole trader and its not trading any longer. Management were looking for buyer not sure if still are.
