Transcript of US/UK Tax Planning

Frazer Rice (00:04 )

Well, we have certainly had a lot of news with British tax law changing. And for those of us here in America who may or may not be part of getting to Europe in a major way and in the UK in a more permanent way, maybe give us a little overview of ⁓ A, what happened, but more specifically, how the UK thinks of US citizens, which can take different forms.

Alex Jones (00:31 )

Let’s start with the back end of that question, how we regard Americans. So from a tax point of view, clearly what we’re really saying is how do we regard Americans who are exposed to UK taxes? And typically that means Americans who are here. Like most countries in the world, the UK will tax people on UK sources of income.

If somebody has a trade or business operating in the United Kingdom, we’re going to try and tax it whether they are here or not. But if the US individuals physically in the United Kingdom, then the UK is going to try and tax them in a number of different ways, which I’ll talk about in a second.

The pause is really just to emphasize the fact that they’re American. So a US citizen or US green card holder is going to be US worldwide taxable, whether they live in America or not. So America is going to look at everything everywhere in an American way in dollars in a calendar year. And at exactly the same moment in time, albeit in the UK we have a different tax year end. Our year end is a rather crazy 5th of April year end.

Exactly the same amount of time the UK is going to look at exactly that same person and say, hey, what are we going to tax? And so you’re starting with the premise that both countries are fighting over who gets the tax first. And the first thing you have to do is look at the two sets of domestic legislation to see how to start, where the problems are, and then you start looking beyond that.

In principle, the UK is going to tax people who are resident in the UK on worldwide income. So anything everywhere under UK rules, UK fiscal year, in sterling, et cetera, et cetera. And somebody who’s not resident in the UK on UK-CITUS connected income only. However, the UK has long had a regime which has been known as the domicile regime or the remittance basis regime, which has been pretty well known internationally where we said,

Look, if you don’t originate from here, if you’re a foreigner coming in for a period of time, could be indefinite, could be reasonably long, but not permanently, then we won’t necessarily tax all things which are non-UK. We would tax things that you brought into the UK, remitted, but we wouldn’t necessarily tax non-UK things that you didn’t otherwise bring or use or benefit from in the United Kingdom.

So the thing that changed in the budget that was announced at the end of October 2024 that largely came into force on the 6th of April 2025 is that we said, hey, this domicile regime, this remittance basis regime is kind of too beneficial to wealthy individuals. You have neighbors who are paying differential amounts of tax just because one person’s kind of foreign and the other person’s a blue blooded Brit who’s lived here forever.

That’s not right or fair morally. So what we’ll do is we’ll say, okay, we’re to do away with this term domicile. We’re not going to use it for income tax or the estate tax purposes particularly. And we’re going to create some new terms. And one of them we’ll create it, which is a four year regime. call the fig regime for an income gain regime where we basically say, again, we’re going to tax UK stuff, but we won’t tax foreign things for that four year window.

But once you’ve been in the UK for more than four years, we’re then going to tax your worldwide income. And then we have an extra piece we’ve added on, which says, if however you’ve been here for a long time, which is basically resident for 10 out of the last 20 years, we’re also going to say, now you get worldwide inheritance tax.

If you die while here, well, if you die with UK stuff, we’re going to tax you on your worldwide assets. as opposed to potentially just your UK only assets, which is how we typically would have treated you if you were a non-domiciled individual under the old regime.

So lots of change as to how the UK taxes people and therefore how we view the American is all about the interaction of the two. It’s all about, yeah, but I’ve got both. I’m an American, I’m paying US income tax, I’m paying US estate and gift taxes. How do I deal with the fact? How do I prevent?

Two sets of taxation globally, such that my income tax rate isn’t a top rate of 37. What I don’t want it to be is 37 plus the top rate in the UK of 45, plus maybe some tax I’m still paying in California or New York because I’ve got a residential property that I’m renting out in one of those two locations. how we treat Americans is we treat them under domestic rules.

We treat them in a way that says what are we or are we not going to tax in our way how we think about things. And by that I mean if we think it’s taxable, it’s taxable. If you guys think it’s municipal bond interest which is exempt, that doesn’t mean anything to UK eyes. We look at it go, well, it’s just interest income. From our perspective, Britain has our own domestic rules which try and stop double taxation. That means give credit for other people’s taxes.

Frazer Rice (05:37 )

Sure.

Alex Jones (05:50 )

And also, most importantly, between the UK and US, we have two tax treaties. We have one tax treaty that deals with UK and US income tax, and we have a completely separate tax treaty which deals with UK inheritance tax and US estate and gift taxes. So we call estate and gift tax inheritance tax in the UK, and it applies in life or death. So we’ve got two treaties which are both trying to minimize unacceptable double taxation. That’s kind of a… kooky term of art,

Minimise unacceptable double taxation. A little bit of double taxation may be acceptable in the eyes of government. Well, these two treaties, they’re designed to try and minimise. So when we deal with both UK and
