Tax code question.

This is an invalid tax code and you should have received notification
from HMRC that your code was changing and why.

Well done Delta that must be the answer.

C means you are in Wales.

As to why it has doubled, dunno. But it could be that the tax computer has over-reacted to your Christmas bonus. That happened to me (not Christmas but a bonus anyway) and the computer decided my regular salary had increased by that much so I was not paying enough tax.

Your case may well be different. You can probably just phone up HMRC or its Welsh equivalent if there is one, and ask. That's what I did.

The W1 at the end means it is an emergency tax code.

Again this is a sign the computer thinks something drastic has changed.

Phone them up, or speak to your HR/payroll department again. HMRC wants everyone to use their online tools but I'm a Luddite.

I've been trying to google with limited success. It sounds like they're not sure what I earn so they use this code - similar to emergency twx rate??

That is kind of what I thought, Ramruma.

Yes, and the 482 is not a very big allowance, but the question is why. If something important has changed, chances are you'd know about it -- eg wife died, massive payrise or whatever -- and if you do not know, the chances are it is a mistake.

So talk to them.

Set up a personal tax log in if you don't already have one (or log in if you do!). Loads of info available, PAYE, NI record, tax code and detail etc.
