The long and the short of the problem is that he has been overpaid three times recently and is now being asked to pay it back. Obviously this is okay, and we will be paying it back, but the kicker is the tax. Technically, DP is being asked to pay his employer money that he never received in his bank account. While we will be able to get this money back in the form of a tax rebate after April, in the meantime, we will be several hundred pounds down until then. We're not on the bare bones of our arses financially, but this will make things very difficult for us until we get that money back fr tax.
Can his employer claim the tax overpayment back themselves, so that DP doesn't have to give his employer money he never technically received, or have we got to suck it up and put ourselves in the shit until the rebate comes through.
Just to be clear, his employers are specifically requesting the full overpayment back, including the tax and NI element.
Sorry for any mistakes in this post, I am a complete novice with any tax and NI issues, and am MNing from my iPhone at work! TIA for any help. :)
