My wife and I were in the UK for a number of years but have left the UK permanently.
We had a very basic tax situation in the UK as all of our income was PAYE taxed, and our annual income was about 60k each. We left the UK in say Sept 1 2018. Unfortunately, I didn't know that we should inform the UK gov of this (more precisely, I didn't know it was so easy to do this online with their forms). This has been done. But now I guess I should probably do a P85 and claim any tax back that we may have overpaid.
We have only one minor complication and I don't quite know how to handle it. Our new jobs in the US started on Aug 1 2018, one full month before we left, so I guess technically, we should be taxed on the income from that job. So, while I thought we were likely to get a refund from the UK govt, we may in fact owe taxes (though in fact I doubt that. my guess is that it more or less balances out). Our new jobs pay slightly more than our old jobs, so I guess in some sense we should be paying tax on approximately one month more of income. My job in the UK ended the day before I left.
I don't quite know what to do. Should we declare the one month's income from abroad? It's not quite that I don't want to pay any tax owing (I assume it will be minor, and the US has a tax treaty with the UK, so I can use it to offset my US taxes), it's the headache and complication I don't want to deal with. There is a part of the P85 form that specifically asks when your new job abroad starts, so it isn't possible to omit the information, I would have to blatantly lie. And since I have already paid tax on that income in the US, i would have to muck about with that too.
any advice will be helpful. Thanks.
