Moving abroad is fundamentally a money operation — taxes, banking, currency, retirement accounts, insurance, real estate. Get the order wrong and you cost yourself $5-50K+ over the first 3 years. Here’s the verified 2026 playbook in order of operations.

Phase 1: 6 months BEFORE moving
Step 1 — Establish your visa pathway
Pick your destination country + visa type from the verified comparison. Income/savings thresholds drive what you need to demonstrate. Most application processes take 3-6 months.
Step 2 — Tax-domicile cleanup in home country
US citizens: establish no-state-income-tax domicile (TX, FL, SD, NV) if currently in CA/NY/etc. See US state residency exit.
UK/Canada/Australia: review your home-country statutory residence tests. Plan exit date to align with tax year for cleanest break.
Step 3 — Retirement accounts
US: roll 401(k) to IRA at Fidelity or Schwab (best foreign-resident tolerance). Confirm beneficiary designations. Consider Roth conversions before establishing foreign tax residency. See 401(k) + IRA abroad guide.
UK: consider QROPS transfer to malta/gibraltar pension only if you’re certain of permanent emigration — irreversible move.
Step 4 — Banking + financial accounts
Open Wise multi-currency account. Open Schwab (US citizens) or N26/Revolut (EU). Keep existing US/UK/etc accounts active — DO NOT close before move.
Make sure all financial accounts have your new domicile address before move (e.g., your TX/FL address if you’re US, your UK address if you’re moving from UK to elsewhere).
Step 5 — Insurance
Cancel domestic-only insurance (US: ACA health if not living in US anymore). Get international health insurance (Genki, SafetyWing, IMG Global, Cigna Global). See Genki vs SafetyWing comparison.
Step 6 — Property + assets
Decide: sell, rent out, or store? Renting out US/UK property: hire property manager + understand non-resident landlord tax (NRL scheme UK, 1099 reporting US). Selling: time gains for tax optimization.
Phase 2: Move month
Document your move: date-stamped photos, lease in new country, exit-of-old-country (cancel utilities, change voter registration, etc). This is your evidence for tax-domicile arguments later.
Notify financial institutions of new mailing address (keep old US/UK address for accounts that require domestic; update phone for 2FA).
Apply for local tax ID immediately on arrival: Portugal NIF, Spain NIE, Mexico CURP+RFC, Thailand TIN, UAE Emirates ID.
Phase 3: First 6 months in new country
Step 1 — Local bank account
Once you have local tax ID + residency permit (or proof of pending), open local bank for daily life (rent, utilities, salary if employed locally). See best banks for digital nomads.
Step 2 — Tax registration
If >183 days expected: register as tax resident immediately. Apply for any favorable regime (Portugal IFICI, Spain Beckham, Italy 7%-flat-south, Greece DN tax break, etc) within statutory window — typically 6 months.
Step 3 — Foreign account reporting (US)
Track all foreign account balances. If aggregate exceeds $10K at any point: FBAR due April 15 (with automatic Oct 15 extension). FATCA Form 8938 may apply depending on residency + balances. See FBAR + FATCA explained.
Step 4 — Self-employment structure (if applicable)
Freelancers/1099/consultants: decide between sole-trader, US LLC, S-Corp, or foreign company. Talk to cross-border CPA before first foreign-source income hits. See US freelancer 1099 abroad.
Phase 4: First tax year completion
File tax return in both countries:
- US citizens: Form 1040 + Form 2555 (FEIE) OR Form 1116 (FTC) + Form 8938 (FATCA if applicable) + FBAR separately. Auto-extension to June 15 for expats, extra to Oct 15 with Form 4868.
- UK leavers: Self-assessment final + P85 to claim split-year treatment if applicable
- Local country: annual tax return in new country (deadlines vary — Portugal April 30, Spain April-June, Mexico April 30)
Phase 5: Year 2+ optimization
Once stable: optimize.
- Review FEIE vs FTC each year — switch if math changes
- Use Totalization Certificate (US + Portugal/Spain/UK/etc.) to waive US SE tax
- Top up IRA / 401(k) only if your earned income still qualifies (FEIE’d income generally doesn’t qualify for IRA contribution)
- Consider currency hedging strategies for major asset sales
- Plan for citizenship application date (5 years Portugal, 2 years Argentina, 3 years Paraguay, etc.) — start preparing 1 year before
Frequently missed items
US estate planning: US estate tax exemption $13.99M (2026) drops to $7M in 2026 (TCJA sunset). Plan if your estate >$5M.
Foreign mutual fund/ETF avoidance: US citizens shouldn’t own non-US-domiciled ETFs/mutual funds due to PFIC rules. Stick with US-domiciled funds (VTI, VOO, etc.) or individual stocks.
Foreign-spouse interaction: US-citizen + non-US-citizen spouse has unique tax rules. Consider 6013(g) election (treat foreign spouse as US resident for joint filing) carefully.
FAQ
When should I hire a cross-border CPA?
If your income >$80K, OR you have a complex setup (multiple countries, US LLC + foreign residency, retirement-account drawdowns abroad, foreign-currency real estate), OR you’re in your first year of move — hire one. Cost $1,500-5,000/year. Pays for itself many times over via tax optimization + audit protection.
Best US-aware cross-border CPAs?
US specialists abroad: Greenback Expat Tax Services, Bright!Tax, Online Taxman, Frank Hirth (UK + US), MyExpatTaxes (free for simple cases). Check credentials + try a free consult before committing.
What if I’m halfway through my move and didn’t plan correctly?
Common. Most issues are correctable — just costly. Streamlined Filing Compliance Procedures (FBAR catch-up), late tax-residency registrations, retroactive Totalization filings — all possible. Talk to a cross-border CPA who specializes in catching up rather than just routine compliance.
