"While you wont convince your employer to pay your income tax for you, you should still, in my view, point out that you are owed a favour and, for example, suggest that you get first choice of dates for the annual holiday or don't get asked to work on Christmas Day, etc.."

Dear oh dear oh dear.

Lets be clear here, an employer has no idea whether somebody they employ is working at the time they take them on. They have only the word of the potential employee.

To start trying to apportion any kind of blame or responsibility of your own tax liability to your employer is a dangerous route to explore, in my view. You would be skating on very thin ice if you tried this with me!

Income tax is a personal liability. Take responsibility.

You should look at your payslips and/or the year end P60 to check for underpayments. There are online tax calculators that will tell you how much tax you should have paid in total during the year. Mistakes happen but if the mistakes have meant that you didn't pay enough tax, they you will have to pay that tax. It's not up to your employer or the payroll clerk to make up any difference. You should be able to discuss how and when to pay with HMRC. They may offer the option to pay over the next 12 month or to pay through the PAYE ststem.

Hi, wondering if anyone can help.

I have received a letter from HMRC stating that I owe £540 as I was working 2 jobs at the same time - I have never done this; I finished one job and started the other straight away. This dates back to September of 2010.

HMRC have been informed and they have agreed that it looks like a mistake. I have spoken to the HR manager of the company that I moved to (and am still employed by) who has said that the MD filed online to say that "Statement A of the P46 was correct". THis is the statement that says that I haven't had a job prior to starting this one. I wasn't asked to fill in a P46.

Do I need to make the payment to HMRC or should this be down to my employer as I believe that it is their mistake?

Many thanks in advance.......
