Hello,
We resorted to managing US and UK tax returns ourselves when the recommended advisor having first said they would help, didn't respond to our emails or messages.
So, my wife receives UK PAYE income and in the UK tax year 2020-21 also took her full lump-sum payout from her 401K (as deposit on house in UK). She also receives a small pension of 91 dollars a month.
We had been told that the small pension and social security payments which she'll be able to claim from next summer, would be taxable in UK and the lump-sum pension taxable in US.
When she took the 401K payment about 10,000 dollars was withheld in the US
She filed her US return for 2020 in May and we were told we would receive 5000 dollars refund from the 10,000 withheld (still waiting for this).
Then in August we completed UK tax return for 2020-21 expecting to have no tax in UK on the lump-sum due to USA claim on this.
We spoke to the specialist technician who showed us the treaty on double taxation online which appears to say all pension income is taxable in the country of residence not country of origin.
This means we owe £9,300 in UK (so a lot more than the US tax was)
Firstly, can anyone reassure us that we do now have the correct information and we owe HMRC UK not IRS USA?
Secondly, is the 1116 form the correct form to submit to get the remainder of the US tax paid, refunded.
Thirdly, is it ok to send the 1116 form now on its own months after the original IRS tax return was submitted?
Fourthly, we think we have found confirmation that the relevant section is 'income re-sourced by treaty' (line 30) but we're confused about the other sections of the form. It also says one form per amount, so should we do one for the small monthly pension and one for the 401K?
Very sorry if this is covered elsewhere. I have been trying to read through, but struggling to follow all the different scenarios, and the amounts we stand to lose with mistake are scary.
Many thanks,
Emily
