UK vs USA in 2026: compare residency routes, the FIG regime, EB-5 thresholds, citizenship-based tax and passport mobility for HNW relocation decisions.
Few cross-border decisions carry more weight for a high-net-worth family than the UK vs USA question. Both are top-tier destinations for capital, education and business — yet they sit at opposite ends of the tax-and-residency spectrum, and both moved significantly in 2025–2026. The UK abolished its 200-year-old non-dom regime; the USA continued to tax citizens wherever they live. This guide compares the two from an advisory standpoint: thresholds, timelines, tax exposure and mobility, with current figures.
The single biggest structural difference is the basis of taxation.
The United States taxes based on citizenship, while the United Kingdom taxes based on residency.
That distinction drives almost every planning decision.
On the UK side, the historic regime is gone.
The historic non-dom regime, once a cornerstone of UK tax for international clients, is abolished from 6 April 2025. It is being replaced by a new, stricter, residence-based system.
In its place sits the FIG regime.
Those individuals who have not been UK resident in any of the 10 consecutive years prior to their arrival will, for their first 4 years of UK residency, not be taxable on any foreign income and gains within that initial four-year term.
After that, the picture changes sharply:
after these four years, you will be taxed on your worldwide income and gains, just like any other UK resident.
There is also a trade-off —
claiming the four-year FIG relief means you may lose your UK personal tax allowances.
The UK now offers four golden years, not fifteen — the planning window has shrunk, so the strategy must sharpen.

UK income tax sits at
20% basic, 40% higher (above £50,270) and 45% additional (above £125,140), plus National Insurance.
Inheritance tax was also re-based on residence:
from 6 April 2025, the concept of "domicile" is replaced by a "long-term UK resident" test for IHT — an individual will now be within the scope of UK IHT if they have been UK resident for at least 10 of the previous 20 tax years.
The USA, by contrast, never lets go of its citizens.
US citizens owe US federal income tax on worldwide income regardless of where they live. Moving abroad does not end your US filing obligation.
The same applies to green-card holders. As Muzaffar Saydiganiev, Managing Director at VisaTier and a licensed investment-migration adviser, notes, the US green card is a tax decision before it is a lifestyle one — citizenship-based taxation and exit-tax rules mean the entry should be modelled as carefully as any exit. This is why we frame relocation through structured tax residency planning for entrepreneurs rather than a single-country lens.
This is where the two diverge most for HNW families. The UK's settlement timeline is in flux.
The UK government has announced major reforms to settlement (Indefinite Leave to Remain). Under the proposed "earned settlement" model, applicants will need to demonstrate stronger contributions, meet tougher suitability and integration standards, and comply strictly with immigration rules.
Concretely,
the model increases the general qualifying period from 5 years to 10 years, and introduces new criteria on the basis of which these 10 years can reduce, or increase, including up to 30 years.
For wealthy applicants there is a meaningful carve-out.
High earners (£50,270+) could qualify after five years; those earning £125,140+ may settle in just three.
Crucially, these are proposals, not law:
the consultation closed on 12 February 2026 and the Home Office is reviewing responses. No draft Immigration Rules have been laid before Parliament and all existing five-year and ten-year ILR routes remain in force unless and until amended.
The US permanent-residence route through EB-5 is, by contrast, a defined investment threshold.
The EB-5 minimum investment in 2026 is $800,000 for a project located in a Targeted Employment Area (TEA), and $1,050,000 for a project outside any TEA.
Each investor must
create or preserve at least 10 full-time positions for qualifying US workers within roughly two years of receiving conditional permanent residence.
Note the timing window:
starting 1 January 2027, the EB-5 investment amount will increase automatically based on inflation (CPI-U), as mandated by law.
EB-5 leads to a green card and, eventually, citizenship — the UK proposals do not change the principle that ILR precedes naturalisation.
| Factor | United Kingdom | United States |
|---|---|---|
| Basis of taxation | Residency-based; non-dom abolished 6 April 2025 | Citizenship-based; worldwide income taxed for life |
| Foreign-income relief | 0% on foreign income/gains for 4 years (FIG regime) | None for citizens/green-card holders; worldwide from day one |
| Top personal income tax | 45% above £125,140; plus National Insurance | Up to 37% federal; plus state tax (varies by state) |
| Main investment route | No formal golden visa; FIG-based relocation | EB-5 green card; E-2 treaty visa (UK nationals eligible) |
| Investment threshold | None for residence per se | EB-5 from $800,000 (TEA) or $1,050,000 (non-TEA) |
| Path to permanent status | ILR after 5 years now (proposed 10; 3 for £125,140+ earners) | EB-5 green card, then citizenship after 5 years |
| Total estimated cost (single applicant) | From ~£15,000–£40,000 in advisory/visa/legal fees (no set investment) | From ~$850,000–$900,000 all-in (EB-5 capital plus fees) |
| Passport rank (2026) | ~6th–7th (Henley Passport Index 2026) | ~10th (Henley Passport Index 2026) |

Both passports have slipped.
The US has suffered the third largest ranking decline over the past two decades — after Venezuela and Vanuatu — falling six places from 4th to 10th, while the UK ranks as the fourth-biggest faller, down four places from 3rd in 2006 to 7th in 2026.
In the April 2026 update,
the United Kingdom ranks sixth with 183 destinations accessible without a prior visa, while the United States sits in 10th place with visa-free access to 179 destinations.
Both also recorded sharp recent losses.
The US and the UK recorded their steepest annual losses in visa-free access over the past year.
For HNW clients, this is precisely why mobility should not rest on a single document. We explore that logic in our analysis of why holding more than one citizenship is now a strategic asset — optionality is insurance you buy before you need it.
For many British entrepreneurs, the E-2 treaty investor visa is the most practical US entry point.
UK citizens looking to invest and run a business in the US may be eligible for the E2 visa program.
There is no fixed statutory minimum, but the investment must be substantial —
although there is no specific minimum amount set by the US Government, your investment capital must be substantial; typically, the investments are from $100,000 and above.
Its flexibility is real but bounded.
The E-2 visa is typically issued for an initial period of two to five years and can be renewed indefinitely as long as the business remains operational and meets visa requirements.
The catch matters for long-term planners:
the E-2 visa is a non-immigrant visa and does not provide a direct route to US permanent residency (green card).
And tax residency can attach quickly —
if an E-2 visa holder spends 183 days or more in the US in a calendar year, they are considered a US tax resident under the Substantial Presence Test.
There is no universal winner in the UK vs USA decision — only a winner for a given profile. A family prioritising a tax-efficient four-year landing, European proximity and education may favour the UK's FIG window while it lasts. A family seeking unconditional permanent residence, the ability to live and work anywhere in the US and an eventual second citizenship may favour EB-5 — provided they accept lifelong US tax exposure. In VisaTier's casework, our licensed advisers consistently see clients underestimate the US exit-tax and reporting burden, and overestimate the durability of the UK's new four-year relief. We don't sell a visa — we build a strategy, modelled on your numbers and timeline.
