Question on USA/UK tax treaty
 

Hi Everyone,

I am looking for anyone who may have some expertise in the USA/UK tax treaty. Last year, my status changed from being a legal resident to becoming a US citizen. I have a UK Government qualified teachers' pension, which as a US legal resident was previously taxed in the UK. Now, I have become a US citizen, the USA/UK tax treaty does not apply favorably to me, and I now have to pay the IRS tax on it. I wish to know, because I became a USC in August, 2019, do I have to pay the IRS tax for the whole years worth of pension or for August to December? i.e. report 7 months of pension as tax free and the remaining 5 months of pension as taxable income?

When I became a US citizen in December 2009, I had to pay US tax on my UK government pension for the whole of 2009. I got back what had been already paid to HMRC. Not sure why you say the tax treaty doesn't apply favorably, I paid 20% to HMRC, and on part of my UK income 40%, and now at most 15% to the IRS. Maximizing deductions in the US is the secret.

If he has not done so already, the OP should complete Form US-Individual 2002 to recover UK tax already paid and avoid UK tax for the future:

When I did this it took a few weeks but the 2 months of taxes I had paid HMRC through PAYE were refunded on my next pension payment.

Thanks for your reply Lansbury and confirming that I have to pay tax on the whole year. I could not find the relevant information in the tax treaty itself, although I am sure it is there somewhere. What I meant about the tax treaty and it no longer being favorable, was simply that the $8000 I received from the TPS was less than my UK tax allowance and therefore was not subject to any UK tax. However, now I have become a US citizen it is taxed as income within the IRS normal US tax brackets.

I can't remember exactly what paperwork I filled out at the time, but no UK tax is taken out at source by the TPS. Now I am a citizen, I pay quarterly estimated IRS tax payments on my UK TPS pension. I think that is all I have to do from now on?

I shall probably buy 1 more year of my UK state pension, then allow it to grow until I turn 70. Then I presume when I actually apply for that pension, I will have to complete the form you mentioned above? Anyway, that is my plan.

Unfortunately for amounts less then the UK personal allowance it isn't a level playing field. Guess those that negotiated the treaty didn't think of that.

Re: Question on USA/UK tax treaty
 

The US also has the standard deduction of $12k for single so if that’s your only income you would also not pay tax on it here. The idea of the tax treaty is to avoid double taxation not to provide you with 2 separate tax allowances that others don’t have.

Re: Question on USA/UK tax treaty
 

Exactly! A consequence of ensuring that you're only taxed once is that you only get one allowance/ deduction.

Re: Question on USA/UK tax treaty
 

Yes, I understand the purpose of the tax treaty, I guess I was just lamenting the financial decision of becoming a US citizen, compared to remaining a legal resident. Overall though, I am still glad I became a US citizen.

Re: Question on USA/UK tax treaty
 

But if you remain an LPR with a UK government pension the tax treaty does indeed allow you to claim two allowances.

Re: Question on USA/UK tax treaty
 

I am interested in this topic, despite being far from retirement age, and found this article from 2018 by a tax attorney that suggests that UK 25% pension lump sums can be made exempt from Federal tax if you get a tax attorney to file specific information with your Federal return. I have no idea if this also applies to states that tax income, but I guess that if the amount was large enough, one could perhaps become a resident of an income tax free state during the time of distribution.

Considering that a 25% pension lump sum could be worth many, many tens of thousands of pounds to some people, it could be worth investigating this more.

Also, it's very interesting to read that the UK won't tax Roth distributions either, if, for example, a US resident was to move to the UK to retire.

Re: Question on USA/UK tax treaty
 

I can confirm from experience that a USC living in the U.K. can take distributions from his Roth with no tax in either the U.K. or USA.

Re: Question on USA/UK tax treaty
 

Very cool. Did you have to file anything with HMRC or the Roth broker to enable that?

Re: Question on USA/UK tax treaty
 

Nothing to file. In the HMRC Self Assessment each year the Roth withdrawal amount is stated along with a reference to the tax treaty in the other information, section 19.
