Moving to the UK from the US: Tax Checklist for Americans
Moving to the UK is exciting, but the tax implications start before you leave. The UK's worldwide income taxation and complex rules for non-doms create unique pre-move planning needs. This checklist covers the key tax steps before, during, and after your move.
Before You Move (3-6 months before)
State Tax Exit
- If you live in California, New York, or another aggressive state, plan your exit carefully
- Surrender your driver's license and obtain a new one
- Cancel voter registration
- Sell or rent out property
- Close or minimize bank accounts in your former state
- Consider establishing residency in a no-tax state before moving abroad
FEIE Planning
- Understand the physical presence test (330 days outside the US in a 12-month period)
- Plan your move date to maximize your first-year FEIE
- Keep detailed travel records from day one
Non-Dom Status Planning
- Research whether you qualify for the remittance basis (being phased out from April 2025)
- The new 4-year foreign income and gains regime may apply to new arrivals
- This significantly affects your UK tax liability and FEIE vs FTC analysis
Totalization Agreement
- The US-UK totalization agreement prevents double social security taxation
- If you are self-employed in the UK, obtain a certificate of coverage
Banking
- Plan for UK bank account opening (requires proof of address)
- Keep at least one US bank account open
- Understand FBAR reporting requirements (including ISAs)
First Year Filing
Partial-Year FEIE
In your first year abroad, you may qualify for partial-year FEIE.
UK Tax Residency
UK tax residency is determined by the statutory residence test, which is complex. It considers days spent in the UK, work ties, accommodation ties, family ties, and other factors.
FBAR
File FBAR for all foreign accounts, including UK accounts (bank accounts, ISAs, SIPPs), if the aggregate value exceeds $10,000.
Establishing UK Tax Residency
- Obtain a National Insurance number
- Open a UK bank account
- Register with HMRC (if self-employed)
- Register with a GP (general practitioner) for NHS access
Common Pre-Move Mistakes
- Not planning state tax exit — California and New York can follow you abroad for years.
- Not tracking travel days — You need 330 days outside the US for the physical presence test.
- Not understanding remittance basis changes — The rules are changing from April 2025.
- Not reporting UK bank accounts and ISAs on FBAR — All foreign accounts are reportable, including ISAs.
- Assuming UK pensions are tax-free in the US — They are not. US tax treatment is complex.
