Moving as an American citizen
Building a life in United Kingdom as an American citizen
Home for many, a tax puzzle for the mobile. Here is what that means for you specifically, from the front door to the tax return to the passport, seen through your American status rather than in the abstract.
Researched from public sources, dated below. Not legal or tax advice.
The verdict
180 days visa-free, then a long-stay route.
As an American citizen you can enter United Kingdom visa-free for about 180 days per entry. That covers a stay, not a life: living here means a long-stay visa or residence permit. Separately, a visa is not tax residence, spend past roughly 183 days a year and United Kingdom can tax you (see Keep).

The sourced facts
Checked Jul 2026- Entry2026 · High confidence
Post-Brexit: no EU free movement. Many nationalities visit visa-free for up to 6 months as a Standard Visitor (an ETA is now required for non-visa nationals). Long-stay: Skilled Worker visa (min salary GBP 41,700 from 22 Jul 2025). An Electronic Travel Authorisation (ETA) is required for visa-exempt visitors as of 2025.
GOV.UK (Standard Visitor visa) - Tax residence2026 · High confidence
Residency is decided by the Statutory Residence Test (automatic tests plus a ties test), NOT a simple day count; 183+ days is one automatic-resident trigger but far fewer days can make you resident via ties. Do NOT treat as a flat 183-day rule: the SRT can make someone resident on as few as ~16-45 days depending on ties.
LITRG (Foreign income and gains regime, tax years from 2025/26) - Citizenship2026 · Medium confidence
Typically ILR (settlement) after 5 years, then naturalisation 12 months later (about 6 years total). Reforms (earned settlement) may lengthen the standard route and shorten it for high earners. 5 years to ILR + 1 year = ~6; the government's earned-settlement reforms are changing timelines (e.g. 3 years for very high earners, longer default for others).
GOV.UK (Apply for citizenship if you have indefinite leave) - Income tax2025-04-06 · High confidence
Progressive income tax: 20% basic, 40% higher, 45% additional (Scotland differs). The non-dom remittance basis was abolished from 6 Apr 2025 and replaced by a residence-based 4-year Foreign Income & Gains (FIG) regime for new arrivals. FIG relieves most foreign income/gains for the first 4 UK-resident years for those non-resident the prior 10 years; claimants lose personal allowance and CGT annual exemption.

Remote income & your company1 remote-work route make foreign or remote income relatively unremarkable in United Kingdom. Running your own company from here is the sharper question: running your foreign company from United Kingdom can make key decisions happen there, so United Kingdom may treat the company as tax-resident (place of effective management) or as having a permanent establishment. That can pull corporate profit into United Kingdom's net. This is the review that pays for itself. Your full, profile-specific company analysis is in the world designer.

Tax residenceHere is the line the category forgets: your visa lets you stay, it does not decide who taxes you, and that is true no matter which passport you hold. In United Kingdom, tax residence typically turns on roughly 183 days a year, the Statutory Residence Test weighs ties and workdays, not days alone; non-dom was replaced by the 4-year FIG regime on 6 Apr 2025 As an American citizen you may also still have filing ties back home, worth settling before you move.
