u/fastsansfurious

I am a UK citizen and have lived in the US for over 20 years. I have UK personal pension that I want to withdraw. Since the personal pension withdrawal is taxed at source in the UK, and all income for US residents are taxed regardless of the source. I will be expecting to get double taxed.

I submitted the DT-US individual 2002 to HMRC as there is tax treaty between UK and US, including the form 6166 from the IRS to prove that I am a US tax payer.

But the application was rejected by HMRC because the DT-US Individual form has a section requiring an IRS stamp. But I cannot find any sources on how to get this form stamp by the IRS.

Has anyone run into to this issue?

TIA
