Best US Expat Tax Services for Americans in the UK (2026)
Filing US taxes from the UK is not optional — and doing it wrong is expensive. We compared the leading services on price, UK-specific expertise, and what each handles best, so you can choose the right one without wasting an afternoon on five different websites.
Why choosing the right service matters
Most Americans in the UK owe little or no U.S. federal income tax once the Foreign Earned Income Exclusion (up to $130,000 for 2025) and the Foreign Tax Credit are applied. But the obligation to file is unconditional — and the penalty for getting it wrong, or not filing at all, grows every year the IRS tightens enforcement.
The services below are not interchangeable. Some are purpose-built software for the expat who wants to file quickly and affordably. Others match you with a licensed CPA who knows UK-US treaty issues cold. Some are better for straightforward salaried returns; others are essential if you have rental income, a self-invested personal pension, or US 1099 clients. Choosing the wrong fit either overpays for expertise you don't need — or underpays and misses something that matters.

Created in 2018 by Americans living abroad, MyExpatTaxes was built specifically for expat filing — not adapted from domestic US software. That origin matters. The platform guides you through the decisions that actually trip up UK-based filers: choosing between the FEIE and the Foreign Tax Credit, handling UK pension contributions, reporting ISAs (including the PFIC question for Stocks & Shares ISAs), and filing the FBAR alongside your return in one workflow.
The Reviewed plan — from around £478 — includes preparation of your return by you via guided software, plus a review and sign-off by a qualified Tax Professional before filing. For most straightforward UK-based Americans, this tier is the right balance of cost and assurance. The Premium plan adds hands-on support and a video consultation with a Tax Professional. With over 4,800 Trustpilot reviews at 4.8 stars, the platform has an unusually strong user-satisfaction record.
- Built for expats, not adapted for them
- FBAR, FATCA, FEIE and FTC in one workflow
- Can e-file prior-year returns
- 4.8★ Trustpilot on 4,800+ verified reviews
- Live chat support across all plans
- Streamlined Procedure packages available
- Pricing in GBP available
- Prices have risen year-on-year
- FEIE vs FTC optimisation not fully user-controlled on base plans
- Very complex cases (exit tax, CFCs) may need a specialist
Taxfyle's model is different: rather than guiding you through software, it matches you with a licensed CPA or Enrolled Agent who handles your return. For Americans in the UK with genuine complexity — selling a UK property, catching up on unfiled years under the Streamlined Procedure, navigating the exit tax before renunciation, or dealing with a Stocks & Shares ISA that triggers PFIC reporting — this human-led approach is worth the higher cost.
The matching process takes into account your specific situation, so you are connected with someone who has experience with UK-US treaty issues rather than a generalist. Pricing is quote-based depending on the complexity of your return.
- Dedicated licensed CPA or EA — not software
- Matched to your specific cross-border situation
- Handles Streamlined Procedure, Form 8854, PFICs
- Right for property sales, business ownership, exit tax
- No fixed published price — quote required
- Higher cost than software-based options
- Turnaround depends on matched professional's availability
TurboTax is the most recognised US tax brand and its expat-specific flow does cover the key situations for Americans in the UK: Form 2555 for the FEIE, Form 1116 for the Foreign Tax Credit, and FBAR reminders. For Americans who have previously filed with TurboTax and want consistency rather than switching, it remains a solid choice.
Where TurboTax is less suited for UK-based Americans is in the nuances: it is primarily designed for the US domestic market adapted for expats, rather than built from the ground up for overseas filers. Its ability to e-file prior-year returns is also more limited than MyExpatTaxes. Pricing is in US dollars.
- Household name — widely trusted brand
- Covers FEIE, FTC, and FBAR
- Expat-specific guided interview
- Option to escalate to a live expert
- Domestic software adapted for expats, not built for them
- Pricing in USD — no GBP option
- Prior-year e-filing more limited than MyExpatTaxes
- Less suited to complex UK-US treaty situations
Tax1099 is a specialist IRS-authorised e-filing platform focused on 1099 forms — the US information returns that apply when you receive freelance, contractor, or non-employee income from US-based clients. If you work remotely for US companies from the UK and receive 1099-NEC or 1099-MISC forms, Tax1099 is built for the filing side of that workflow.
It is important to understand what Tax1099 is and is not. It is primarily an information return platform, best for the 1099 filing itself rather than a full expat tax return service. Americans who need their full Form 1040 completed will typically use Tax1099 alongside another service for the return itself.
- IRS-authorised e-filing for 1099 forms
- Efficient per-form pricing for contractors
- Purpose-built for 1099-NEC, 1099-MISC and related forms
- Not a full expat tax return service
- Does not handle FEIE, FTC, or full 1040 preparation
- Needs to be combined with a full return service for most expats
Sage is a well-established UK accounting software brand used by hundreds of thousands of UK small businesses. For a self-employed American in the UK, it solves a different problem from the other services on this list: it helps you manage your UK bookkeeping, invoicing, and VAT, and prepares you for UK Self Assessment — the HMRC obligation that runs alongside your US filing requirement.
Sage does not prepare your US return. Its value for Americans in the UK is in organising UK business income cleanly so that when you (or a specialist) file both your UK Self Assessment and your US Form 1040, the numbers are clear and correctly tracked.
- Industry-leading UK accounting & bookkeeping
- VAT, invoicing, Making Tax Digital ready
- Widely supported by UK accountants
- Integrates with UK banks
- Does not prepare or file US returns
- Needs to be paired with a US expat tax service
- Monthly subscription cost adds up

- →You have used TurboTax before and want to stay with a familiar brand for a straightforward return — TurboTax

For most Americans living and working in the UK — employed, self-employed, or with typical UK finances — MyExpatTaxes is the strongest combination of price, expat-specific design, and track record. If your situation includes genuine complexity (property sales, Streamlined catch-up, exit tax, business interests), Taxfyle's matched-CPA model is worth the extra cost. The two services cover the vast majority of situations Americans in the UK actually face.
What to look for in a US expat tax service
Before signing up with any service, it is worth checking five things that matter specifically for Americans in the UK:
There is a meaningful difference between tax software built for US residents that includes an "expat section" and software built for expats from the ground up. The former often lacks nuance on treaty elections, pension treatment, and the FEIE/FTC optimisation that reduces your UK-based liability the most.
The UK-US tax treaty has specific provisions that help Americans in the UK — the pension deductibility rules, the Social Security article, the treatment of lump sums. Not every expat tax service applies these correctly. Ask whether the service handles Article 17 pension elections and Form 8833 protective treaty claims.
The FBAR (FinCEN Form 114) is a separate obligation from the tax return, but the two should be coordinated. A service that files your return but leaves you to handle the FBAR separately creates unnecessary risk. MyExpatTaxes includes FBAR in the same workflow as the return.
Your return should be prepared or reviewed by either an Enrolled Agent (EA) — a federally authorised US tax professional — or a Certified Public Accountant (CPA). Both can represent you before the IRS. Avoid services where it is unclear who is preparing the return or what their qualifications are.
Americans who did not know about their filing obligation need to catch up on back years. Not all software can e-file prior-year returns. If you are behind, confirm before signing up whether the service can handle prior years and whether it offers the Streamlined Foreign Offshore Procedure.
The right service for any given American in the UK depends almost entirely on the complexity of their situation — and that complexity is often invisible until you start filing. A straightforward salaried employee with one UK bank account and no property is genuinely well-served by a purpose-built software platform. Someone with a former rental property, a self-invested pension, and unfiled years from before they knew they had to file is in different territory entirely, and software alone will not get them there safely.
The most common mistake is underestimating complexity. Most people who ended up with penalties, IRS notices, or missed treaty elections did not start out thinking their situation was unusual. The five criteria above — expat-specific design, treaty knowledge, FBAR coordination, preparer credentials, and prior-year capability — are the practical checklist, and they cut through most of the noise when comparing services.
Whichever service you choose, the most important thing is getting filed. The IRS Streamlined Procedure exists specifically for people who got behind without knowing they needed to file — but it only works if you use it before the IRS finds you first.

Frequently asked questions
It varies significantly by complexity and service. Software-based services like MyExpatTaxes start from around £478 for a Reviewed plan with professional sign-off included. Matching services like Taxfyle are quote-based, typically higher for complex returns. A straightforward salaried return with FEIE or Foreign Tax Credit and an FBAR is usually at the lower end; returns with property sales, self-employment income, or PFIC reporting cost more.
For your US return specifically, you need a service with expat expertise — not necessarily full UK tax knowledge. The US return requires understanding of the UK-US treaty, pension treatment, and FBAR reporting for UK accounts. For your UK Self Assessment (if you file one), you will either need a UK accountant or a service that coordinates both sides. Sage helps with the UK bookkeeping side for self-employed individuals.
Yes. If your non-compliance was non-willful — you simply did not know — the IRS Streamlined Foreign Offshore Procedure allows you to catch up on three years of returns and six years of FBARs, paying a 5% offshore penalty. Both MyExpatTaxes and Taxfyle offer Streamlined Procedure packages. Use this programme before the IRS contacts you — once they do, the penalty-free window closes.
Yes, TurboTax has an expat-specific filing flow and covers the FEIE, Foreign Tax Credit, and FBAR. It is a legitimate option — particularly for Americans who have previously filed with TurboTax and want continuity. The main limitations for UK-based Americans are its domestic-first design, USD pricing, and more restricted prior-year e-filing compared to purpose-built expat software.
Mistakes can be corrected by filing an amended return (Form 1040-X). If the mistake involved missing FBAR filings, the Delinquent FBAR Submission Procedures or Streamlined Procedure may be appropriate. The critical factor is acting before the IRS identifies the error itself — proactive correction typically results in significantly lower penalties. This is one reason having a return reviewed by a qualified EA or CPA is worth the cost for most expats.
Most Americans living and working in the UK need to file both. The US Form 1040 is required annually if your worldwide income exceeds the filing threshold. The UK Self Assessment is required if you are self-employed, have rental income, have income above £150,000, or have claimed certain reliefs. The services on this page handle the US return; for UK Self Assessment, a UK accountant or a service that coordinates both filings is needed.
