Talking Expat Taxes #18
UK/US Investing: Avoiding PFICs, ISAs & SIPP Pitfalls
Cross-border investing gets complicated fast when you're juggling UK and US tax rules on the same portfolio. In this episode of Talking Expat Taxes, Alex McGowin talks with Luke Papalias, a dual-qualified US/UK financial advisor at Tanager Wealth Management, about the investment traps that catch expats moving between the two countries. They cover why PFICs make UK mutual funds and ISAs a costly mistake for US taxpayers, how SIPPs get treated differently under the tax treaty, and what happens when banks and pension providers cut off clients simply for having a US address. Whether you're a Brit moving stateside or an American headed to the UK, this conversation lays out what to fix before you relocate - not after.
Show Notes
“The number one UK/US financial advice is to avoid PFICs. That's number one.”
Takeaways
PFICs Are the Core Risk
UK mutual funds and ISAs are typically classified as Passive Foreign Investment Companies for US tax purposes, triggering excess distribution taxation near 37% plus interest charges - one of the highest possible tax rates on anything.
SIPPs vs. ISAs Get Different Treatment
SIPPs are generally treated as foreign pension trusts under the US/UK treaty (requiring Form 3520 but avoiding look-through PFIC issues), while ISAs are typically treated as ordinary investment accounts with no such protection.
FATCA Cuts Both Ways
US citizens abroad often get turned away by foreign banks and advisors unwilling to handle FATCA compliance, while UK pension and investment providers frequently drop clients the moment they discover a US address - sometimes with only a weeks' notice.

Thanks for subscribing! 🎉
Welcome to another episode of Talking Expat Taxes. Very excited to have Luke Papalias on today, and We're gonna talk about a topic that has been, you know, a big part of what I've done over the past several years, which is working with a lot of UK clients in particular, but it has a much broader implication to that than just the UK, in some instances.
But we'll talk a lot about the specific UK/US concepts with, specifically with investments. So, I'll let Luke introduce himself and tell more about exactly, what he does. So Luke, glad to have you on. Appreciate you coming,
Thanks, Alex. I'm very excited to be here
Yeah, so I was thinking maybe just to start off, just give a little bit of background into your history, what qualifies you to talk about, to talk about US/UK, investment, advice and that sort of thing. So a little bit of background.
Luke’s Background Story
So look a little bit about my background. So I'm a dual qualified US, UK financial advisor, so I have the qualifications in the UK, um, also in, in the US. A bit about my history. So I've always had a passion for finance, so I've always loved everything to do with finance since I was quite young.
You know, buying my first stocks when I was 18 and really got into that side of investing, you know, quite early. Also always had a passion for psychology. So I, originally wanted to be a psychologist. That was one of the career paths. So combining the two, finance and psychology really, you know, worked as a financial advisor.
I think that really combines those two aspects from my day to day. Um, in terms of the expatriate side of things, I started my career in Australia, you might be able to tell from the accent, and didn't start in financial planning straight away. So I started in an accounting firm, one of the big international accounting firms for three years.
Realized that there was a lot of the technical aspect that I enjoyed, but I had more of a passion for the financial advice side. So I was luckily enough to get an internship at quite a prominent financial advice company in Perth, uh, Western australia, where I'm from, and been hooked on it ever since
Okay, very cool. I don't know why I never picked up... I just assumed you were from the UK. Now that you say that, your accent, it's very obvious to me.
Yeah, I focused on UK expats for a long time, so there's just so many in Australia. So that's been a big part of my career, but I am from Australia, yes.
Yeah, and Australia has, there's as many issues with Australians moving to the US and the superannuation funds, which we can get into a little bit too.
Correct. Yeah. We have some Australian clients as well
So tell me, tell us a little bit about where you're working now, what you do, who you work with, and then we can dig into some of the fun stuff.
Tanager Wealth Explained
So I work, uh, for Talenger Wealth Management. So we are a US-UK financial advice firm. So we're dual licensed, head office is in London. We have about 50 staff across three offices, so the London office, the Houston office, where I'm based, and then the Philadelphia office. So little bit different to other advice firms out there in that dual licensing, so SEC registered, FCA licensed, and we can provide advice to expats across both countries
Interesting. Just to paint a little picture of, like, the type of clients that I see, UK person moving to the US, they become US taxpayers, and they leave the UK tax residency net at some point during that transition. But there's always the question of what do we do with the assets, right?
Like, how do you start investing in the US, stop investing in the UK? So when you say you're dual licensed, that means that if a UK person has a SIPP or an ISA or something like that in the UK, you can manage that for them as well as help them start investing in the US. You can do both.
yeah. So we can manage, take a SIP, for example, so we can manage that. We would still keep that SIP in the UK. Um, we would manage it, invest in, low-cost ETFs or individual equities, whatever it might be, as well as taking on those US assets as well. Um, ISAs are an interesting one. Can be a PFIC issue depending on how they're structured and the underlying assets, so we would obviously review that.
But iSAs also have their place for clients that might be, say, in the US for a short stint and then planning to return to the UK
Right.
PFICs and ISA Pitfalls
Yeah, so let's talk about that a little bit with the PFICs. I mean, the biggest problem that I see, and probably that you see with, US taxpayers that have UK or really international investments in general, but UK in particular in this case, is if they're invested in non-US mutual funds, that triggers this PFIC regime, and I'll quickly explain it.
Basically, PFIC stands for Passive Foreign Investment Company. Mutual funds fit that definition because they are by definition corporations, foreign corporations whose assets and income are all passive or majority passive. So that falls into this PFIC regime, which is not great, actually terrible from a US tax perspective 'cause you're taxed at essentially 37% is under the default excess distribution regime.
There's interest charges and things like that, and it's doubly bad because if you're in, say, an ISA in the UK, which is, what does that stand for? Investment savings account. Um, there's no tax in the UK on those, so you're just getting this one tax charge from the US. So the entire point of this investment in the first place in the UK was tax deferral.
You've now lost that as a US taxpayer because you're gonna be paying tax on it and at a bad rate. So yeah, they're pretty ugly, and so that's, to me, that's one of the biggest values of working with someone like you, is you understand the US implications of the investments people are making in the UK.
And that's the biggest trouble that I run into is if we're not communicating ha-having someone that understands even if you're not like a un- you're not obviously preparing US tax returns, but you understand the implication of what a PFIC is, and we need to avoid this thing at all costs.
It's, it's really, that's like number one, like UK/US financial advice is avoid PFICs. That's kind of number one.
Exactly. PFICs is the number one. Yeah, we, as you said, so we don't actually prepare the tax returns. I mean, we would leave that to the experts such as yourself on the tax matters, but we are well-versed in the US-UK tax treaty, and particularly as it pertains to investments. So we'll always start with that initial analysis of the client's portfolio, look at, okay, where are the potential, issues here?
What needs to change? Um, and conduct all of that preferably before they make the move
Mm-hmm. Yeah, 'cause that's one thing, 'cause usually I don't have the benefit of working hand in hand with an investment advisor, especially not one that knows the US and UK rules. So a lot of times, like a client comes to me and they've already moved to the US from the UK and say they have an ISA or, or an investment account in the UK, and it has four mutual funds in it.
So in that scenario, what I'm having to do is trying to figure out, all right, how do we get out of these things? Do we not? The strategy depends on what the intention is of the client, right?
Are they, are they here to stay in the US? Is it gonna be a temporary thing?
In which case there's no easy way to get out of a PFIC. The only way to do it is to trigger a sale in the US basically. So like you said, do it before you leave the US or come to the US or find some way to get out of it later. Let's back up a little bit.
Who They Help Most
So what's a typical client that, that you work with? What's a typical scenario?
Sure. So a typical client that I would work with, uh, is, a couple of types, but I'll give you a, you know, one example is UK client coming to the US. Um, they might be UK citizen here on a work visa, maybe transferred within their company. And, they're here to increase their earnings and build wealth.
In terms of the long term, a lot of clients, maybe they don't know, it might be a short-term assignment, but they may stay longer depending on how things develop.
Um, so that's one type of client. The other is American clients that have perhaps worked in the UK, so they've worked overseas, they've been there for a certain amount of time, and now they're coming back to the US.
So there's probably the major sort of types of clients that, that I work with. There are of course, people leaving the US to the UK as well. Um, we see that more perhaps for retirement reasons or lifestyle reasons.
There's a few different kinds of clients that we typically encounter.
Yeah, that makes sense.
Why Invest in the US
And then, so from an investment perspective, what's the general advice there with people that have like retirement accounts? Let's say most of their retirement is in the UK, but they're now living in the US. Are you trying to get assets into the US? Or what's the I mean, I'm sure it depends on the scenario, but I'm
Yeah, I mean,
what's the,
US citizens usually we are, you know, because unless they're planning to, sort of forfeit that US citizenship, it's gonna follow them for life no matter where they are. So that being the case, we always say, "Look, this is gonna follow you around. You always have to keep the IRS happy." Having investments in the US makes it simpler and cleaner so that we can invest in ETFs. Um, you know, we don't have PFIC issues.
We can hold accounts in the UK, so we can still manage that. So if they wanted to hold a GIA while they're living in the US, that's fine. We would just need to make sure that it's invested in individual equities, individual bonds to get away from any of those PFIC
issues.
Less flexibility,
less flexibility, um, higher fees in the UK considerably. So I would say yes, US where possible, for US citizens and even
you know they're not gonna stay in the US or something like that. But honestly, even then, it's not a bad deal, right? I mean, what I always tell my non-resident clients, the US is the best, is one of the biggest tax havens in the world. If, as long as you're not a citizen, right?
Like, I mean, investing in the US as a non-resident's a great deal. No capital gains tax. Depending on where you are, low dividend taxes, no interest tax.
Yeah, even for clients not planning to be there. So, you know, there's a few options they might be able to, transfer depending on what country they're going to after, or they may keep those investments in the US. Um, as you said, yeah, 100% agree with that. There's a lot of advantages having investments in the US. Estate taxes might be an issue for non-residents. Some of the treaties with different countries do cover that, but that can sometimes be an issue.
But yeah, even for our non-US citizen clients, say they're here on a work visa or, green card, majority of the assets are predominantly in the US most of the time.
Yeah. You know, I just had a call with a client a couple days ago. He was actually in the Netherlands. He was born in the US and he moved back to the Netherlands when he was, like, a baby. Never knew he was a US citizen, and then he like, this is a typical, like, accidental American scenario, right?
And so he goes to a bank when he's, like, 20 years old and tries to get a loan or bank account or whatever it was. They find out he's a citizen. They tell him, "Nope, we're not working with US citizens." And he's, he didn't even know he was a US citizen. The bank told him somehow or another. But then, so then he found out he couldn't get bank accounts in these places, and now he's dropping his citizenship in the US is the plan.
FATCA and Account Access
I was curious, are you running into many people that are having trouble... Ooh, this just made me think of another point I need to bring up. But are you running into people that are having trouble in the UK, as US citizens getting accounts and things like that? And then the flip side of that, just so I don't forget to ask, is people outside the US with US accounts.
Like, one of the main values of what you do is working with expats. You know, like you can work with a US person in the UK, whereas I have clients that Schwab tells them, "You gotta get, you have 60 days to get your IRA out of Schwab 'cause we found out you live outside the US," which is a huge problem. But let's tackle the first one first, FATCA.
Are you running into any client scenarios where US citizens are having trouble getting accounts outside the US?
Definitely. Yeah, we face that a lot. So they have difficulty, obtaining investment advice because the advisors don't want to deal with them because of the US connection
Is it just, and is it just the paperwork involved? Is that really what it comes down to? Which I think is the same problem on the US side, not dealing with US expats
It's the paperwork, yeah, because obviously FATCA is unique to the US and it's different to the, common reporting system that, you know, most of the rest of the world uses. A lot of companies, particularly smaller firms, have decided it's just not worth that added cost and complexity to comply with it.
Even some of the major banks, have taken that path. So yeah, we do, speak to a lot of clients that people just don't wanna provide advice to them or they give them very limited kind of advice. And that's where we can step in and really, give them that full, more holistic advice
Right. So, you can help like just a US expat living in the UK, which, in which case I still recommend even not as an investment advisor, if you're gonna make investments, do it in the US in that case. We have to, we still have to figure out the UK tax because the UK has their own version of PFICs that I don't fully understand, very well.
But, I don't think it's as big a deal as the US one. That's like a very loose way of putting it.
UK Reporting Funds
Yeah, so the UK, they'll look at reporting or non-reporting funds. And if they're non-reporting funds, then there is a higher tax rate, for that. So we do an analysis on all client portfolios as well, if they're moving to the UK or they may already be in the UK. And we make sure that they're all UK reporting funds as well as being compliant with the IRS. So, there are ETFs that meet that, definition, but I would say the majority are not UK reporting funds. So it's really, that's another area that, we really need to analyze the client portfolio and make sure they're compliant.
Right. Yeah, definitely. On the US side of things, I guess that's a really important point, though, that you're able to help, these people that, can't get the accounts that they need in the UK and you're able to manage those investments. But also on the US side, like if there's somebody that's a US citizen and they move outside the US, that's one of the crazy things that I've found with clients is, there's no consistency with when a US bank or financial institution shuts somebody out of the system.
Like, if they move to the UK, there's no consistency with it, and I think it's just, the, the decision of the actual, like the branch of the bank. It might not even be the whole entire bank itself. But how do you deal with those clients?
Obviously you only, are licensed to manage, assets in the UK and the US. But what if you have a client that lives in Australia or Costa Rica or something like that? Are you still able to help those clients, or are there certain countries that even y'all don't work with?
Yeah, generally we are, you know, within reason. There, there are some, countries if they're on, a blacklist or something that we might have to stay away from, you know, account opening and there might be, a lot more AML requirements. But generally speaking, if it's say a US expat and they're living in, Australia or another country, we can still advise on those US-based assets.
We can still prepare their financial plan and, strategy and all of that type of thing. But it would just be, the advantage we have in being able to manage funds in the UK and the US is that we can really manage everything in the client's portfolio, so it's very holistic. But yeah, we have clients from all over, and, a lot of immigrants particularly, or people, here as an expat in the US, they build a substantial portion of their wealth in the US, so
they might have 80% of their wealth built through, RSUs or, bonuses and income that they've earned in the US, so we can manage that.
Um, they might have a small portion back home, which may be in a property or savings or something similar.
So you're able to, help manage and it doesn't matter what country they're in necessarily. I mean, generally the advice for US citizens is as far as an investment goes, unless you're planning to exit your US citizenship one way or another, keeping your investments in the US, is a much better way to do it just 'cause it's more flexible.
You're not having to play these PFIC games at the end of the day like you would
I agree. It is more, more flexible. You know, it's cheaper. Most of the platforms these days, such as ones that we use, there's no trading fees for stocks or ETFs. Whereas a lot of the foreign platforms, they'll charge, a lot of additional fees. So
there's quite a few advantages, and just the breadth of opportunities in the US I think is quite unmatched as well.
Yeah, definitely.
SIPP vs ISA Tax Treatment
So, let's talk a little bit about like the I did wanna dive into a little bit like the products, like specifically with the UK and the US. You know, we deal a lot with people that have, the retirement plans in the UK, the SIPP and the ISA. I was just gonna...
I mean, A lot of these things have a lot of gray area, right, as to how they're, how they're classified for US tax purposes. And I'm probably, there's probably, you know, you could probably ask five people this question and get four different answers at least as to like how the US is going to treat SIPPs and ISAs and things.
And actually, I just had a client, that I'm working with now that one of the complications she has, she lives in the UK, she has investments in, I think it's a SIPP that she has investments. And the SIPP is typically a better deal from the US perspective because at least it's a retirement account, right?
Ag- agreed, yeah
so then we get the treaty benefits where, yeah, it may still be a foreign trust foreign grantor trust where we have to file Forms 3520 in the US, so it's a little bit of additional compliance. But we don't have to look through to the underlying assets and pick a, and then we don't have PFIC problems.
Whereas the ISA's a different story. At least my position on the ISA is it's more like an investment account.
So we're not, we're not treating it like a retirement account. Is that generally the way you see it treated?
100%, yeah. So SIPs, as you say, at least it's protected from, the underlying investments. Um, you know, that's not so much of an issue. But ISAs, yes, we see it as a normal investment account, and most of the time if people are gonna be here for five years plus in the US, it usually makes sense to get rid of the ISA and put that into a brokerage or another kind of investment account. If there were really high unrealized capital gains, then maybe it may make sense to, to keep it and just make sure that there's no PFICs
Right
in there. But otherwise, a US brokerage probably makes more sense
Moving UK Pensions to US
All right, so I'm gonna talk one more... So this part's a little trickier, I think, but that's trying to get, like let's say you have a client one person you mentioned is like a US citizen that spent, you know, a decade in the UK working, and then they move back to the US and they're gonna stay in the US, but they have, several hundred thousand dollars or something in UK requirements.
Getting those assets to the US, one thing I'm working through now with clients is the UK lump sum distribution rules. I know you're not a tax expert, but you run into these same problems that, that I
Sure
And it's like, yeah, we can, you can get it out of the UK tax-free, but the US is still gonna tax it coming out.
I mean, have you personally found it worth it in like broad stroke trying to move UK assets to the US or does it really just depend
It, it really depends on the individual client. Yeah, I wouldn't say it, as a broad brush, it will always work. It would really depend on the individual circumstances. We'd always work with, someone such as yourself, a, tax expert to see what the repercussions are gonna be, in the US.
What is the benefit of doing that? Let's say somebody has a SIPP in the UK, and we know they're gonna stay in the US for a long time. Is there really a downside to keeping that, just keeping the money in the SIPP and opening up something else in the US if you're still working, whatever it is, or just waiting?
I mean, I'm pretty sure what the UK-US treaty says is you're gonna pay tax on the dividend, on the distribution in the resident country,
Correct. If you took a SIPP, for example, we would nearly always recommend keeping it in a SIPP structure. So we can manage that. We have that UK license, so we, have access to SIPP providers so we can manage that, um,
Right. See, I think that's a huge benefit to people 'cause like, you said, fees is a problem, but if somebody has a SIPP in the UK and moves to the US and they wanna get a financial advisor to start managing US stuff, they're gonna have to keep their UK advisor to do that part 'cause it's not gonna ever really make s- I mean, never say never, but moving the SIPP to the US is not really an efficient
It doesn't usually make sense.
'Cause you're not subject to the PFIC stuff, so it's tax deferred either way. You're still getting tax deferral in the SIPP, so
Exactly. I mean, the cases I've come across where clients have done that without advice, so they've just sort of withdrawn everything and moved to the US, there's a few trigger points. So a lot of the time you'll find that the SIP providers won't keep clients on board once they become US residents. So we've had quite a few examples I can think of.
Ah, so like the opposite scenario of the US
Yep.
situation.
Yeah, we've uncovered that a lot and clients have come to us and said "Look, I've just got this email that I have until the end of the month to leave the platform.
What do I do?" And it's not easy once you have the US address, SIP providers won't take you. So we have those, relationships to be able to, have, SIP providers that will take them on as well.
Okay. I'd never actually heard that before where people... Probably 'cause a lot of my clients keep a UK address, and so they probably do the same thing my US clients do. They just pretend they still live in the US and they move
and maybe it got found out
that strategy. , But it's not a foolproof strategy, I guess is the point, because there's ways, first of all, there's ways for them to know that you don't live in the US. But, but yeah, using your... I imagine they do this, people do the same thing in the UK they do in the US, use their parents' address or whoever, brother's address in the UK so they can keep their SIL, and nobody ever asks any questions.
And that probably works 95% of the time to do it
Yeah. And is that 5% then it doesn't. But as you mentioned, getting advice on it is a difficulty as well. So usually their UK advisor may not still advise them or they have to have a separate advisor, so they would have to have a US and a UK advisor.
Right.
Why Cross-Border Teams Matter
Yeah, 'cause I mean, at the end of the day, like you can play that game to keep the sip there, but you still need to be able to ask people questions, and the answers to your questions have to include the fact that you're now a US tax resident. If you leave that part out of the, out of the situation, then you're not getting good advice.
There's just no way. So you really need somebody that can do both, or at the very least two people that are able to communicate intelligently with one another, which is harder than just having one person at the end of... Um, 'cause that, I mean, that's a lot of what I do really, is coordination.
You know, when it comes to US people living outside the US, I need to have qualified people in their own camps, so UK tax people that I work with, US-UK advisors like you, so that we can put our heads together and figure out the right solution, 'cause nobody knows everything,
Yeah, 100%.
And that's, that's where you need to be careful when people say they do, you know?
Definitely. No one, no one knows everything. I agree with you on that, and having that team so, you know, cross-border, experts such as yourself on tax, people such as ourselves, and then, estate planning attorneys, whatever it might be, having that team behind you is really important. We always really emphasize that with clients
Yeah, for sure. All right, cool.
