The Expat Financial Checklist: What Mid-Senior Professionals Get Wrong Before They Relocate

The pattern repeats often enough that I recognize it now. Smart person. Senior role. Company relocation or a self-initiated move. They've done real research — cost of living comparison, international school rankings, which neighborhoods are safe, how the healthcare system works. They arrive prepared. Six months later, they discover a tax or financial consequence that was entirely predictable, entirely avoidable, and that nobody in the relocation process thought to mention.

The research most people do for an international move is arrival research. It answers: what will my life look like when I get there? It doesn't answer: what financial decisions need to be made before I leave?

Those are different questions with almost no overlap. And the second one — the departure question — has a harder deadline. Most of the consequential decisions in this checklist can't be made after you've left. The window closes when the moving truck arrives.

This isn't directed at any specific corridor. It applies to a Director at a US company moving to Singapore, a senior manager in Germany relocating to Canada, an engineer in India moving to the UAE. The specific rules differ. The category of decisions is the same.

1. Tax Residency Departure Date

The date you formally cease tax residency in your current country is not automatically the day you board the plane. Different countries use different tests — days present, center of vital interests, where your family lives, where your permanent home is. Leaving on December 30 vs. January 2 can determine whether you're a tax resident for an entire year or just one day.

In Germany, for example, you remain subject to unlimited tax liability until you deregister your residence (Abmeldung) and meet the non-residency test for the full year. In France, you're considered resident for the entire year if your household or principal place of activity is in France at any point. The US uses a different test entirely — the "substantial presence" day count, which is mechanical but creates surprises for people who travel back frequently.

The practical question: in the calendar year of your move, are you filing as a full-year resident, a part-year resident, or a non-resident in your origin country? Each of these produces different tax calculations. Some are significantly better than others. The date you choose to leave — and how you structure the residency break — is a decision worth a 2-hour conversation with your tax advisor before you book the movers.

2. Equity Compensation: What Happens to Your RSUs and Options Mid-Vesting

If you have unvested RSUs or options, moving internationally mid-vesting period creates what tax professionals call "source allocation" — the portion of the award that vested while you were in country A is taxed there; the portion vesting while you're in country B is taxed there; the portion vesting while you were moving between them requires an allocation formula.

Most companies have a tax equalization or tax protection policy for internationally mobile employees. These policies range from excellent (company pays the higher of home or host country tax, you're held harmless) to misleading ("we'll help you file" but no actual equalization). Read your specific policy before you accept the transfer. Ask directly: if my total tax burden in the new country is higher than it would have been at home, who pays the difference?

For ISOs specifically: moving internationally while holding unexercised ISOs is genuinely complex. The $100,000 annual ISO limitation interacts with the holding period requirements in ways that depend on which country you're in when you exercise. An ISO exercised in the US gets ISO treatment. An ISO exercised as a non-US resident may not. If you have significant ISO exposure and you're moving, this needs professional attention before you leave.

3. Old-Country Pension and Retirement Accounts

The default for most people: don't touch the retirement accounts from your origin country. This is usually correct. But there are specific situations where doing something before you leave is better than doing it after.

US 401k when leaving the US: You cannot continue contributing once you stop being employed by a US employer. The account stays where it is. Roll it to an IRA before you leave if your 401k has limited fund choices or high fees — this is easier to do while you still have a US address and US phone number. Do not cash out. The 10% early withdrawal penalty plus income tax on the full amount is punishing.

UK ISA when leaving the UK: ISA contributions stop when you become non-resident. The existing balance continues to grow tax-free within the UK, but you can't add to it. Leave it. The tax-free growth is valuable and withdrawals when you eventually return (or in retirement) remain tax-free in the UK.

Indian EPF when leaving India: You can either withdraw (tax-free if the account is 5+ years old from the start of your first EPF contribution, across employers) or leave it earning interest. Once you become an NRI, you can't contribute but the balance continues to compound. The decision to withdraw vs. leave depends on your expected return to India and on the US tax treatment of the ongoing accrual — see the separate note on EPF and US reporting requirements if you're moving to the US.

The irreversible one: Some pension decisions can only be made while you're still employed and resident. In certain countries, the option to transfer pension credits to a new country (under a totalization agreement), to commute a defined benefit to a lump sum, or to change beneficiaries is only available before the employment relationship ends. These decisions have a hard deadline.

4. Which Bank Accounts Will Survive the Move

Many financial institutions close accounts when you become non-resident — or they don't close them, but they stop being useful. This is easy to discover after the fact and annoying to fix from another country.

In the US: several major brokerages — Vanguard, in particular — will not maintain accounts for non-US residents. They notify you when you update your address, at which point you have a limited window to transfer assets out before they're liquidated and sent to you. If you have a Vanguard account and you're leaving the US permanently, either transfer to a brokerage that serves non-residents (Schwab is generally more accommodating, Interactive Brokers specifically caters to international clients) or set up a US mailing address (a family member's address) before you notify anyone.

Credit history is a separate issue. If you close all your accounts in your origin country and return years later, you'll have no credit history and start from scratch. Consider keeping one credit card open with a small recurring charge and auto-pay to maintain the history without ongoing attention.

Set up banking in your destination country before you arrive if at all possible. Some countries allow non-resident account opening (Germany with N26, the Netherlands with Bunq, most of Southeast Asia). Arriving with a working local bank account and an international transfer setup (Wise is the practical standard) removes a category of stress from the first month.

5. Tax Treaty: What It Does and Doesn't Cover

If your origin country and destination country have a tax treaty, it determines how specific income types are taxed when you have ties to both. The treaty doesn't eliminate dual filing requirements — it prevents double taxation on specific items.

Things tax treaties commonly cover: which country taxes employment income during the transition year, how pension income is taxed once you retire in the other country, capital gains treatment on property sales, dividend and interest withholding rates between the two countries.

Things treaties often don't cover or cover poorly: social security contributions (covered separately under totalization agreements), state-level taxes in the US (federal treaty, not state), income from third countries, and wealth taxes in countries that have them.

Before you move, your international tax advisor should be able to identify the three or four treaty provisions most relevant to your specific situation — the pension article, the employment income article for your transition year, the capital gains article if you hold property in either country. Not a general overview. Specific articles applied to your actual asset and income structure.

6. Social Security and Pension Contributions

If your origin and destination countries have a totalization agreement, it prevents you from paying social security contributions to both simultaneously and ensures the contributions count toward your benefit in both systems proportionally. The US has totalization agreements with 30 countries including most of Western Europe, the UK, Canada, Australia, and Japan.

Countries without US totalization agreements include India, China, Brazil, and most of Southeast Asia. If you're moving from the US to India on a local hire contract, you may pay into India's PF system while also having accumulated US Social Security credits — and the two systems won't recognize each other. You'll need 40 quarters of US Social Security credits to qualify for US benefits, and those quarters must come from actual US employment. Time spent in India doesn't count.

If you're close to qualifying for a meaningful pension in either country — 35+ years toward a state pension in the UK, 40 quarters toward US Social Security — understand what the move does to that timeline before you leave. For some people near retirement, this is a deciding factor.

7. The Insurance Gap Nobody Plans For

Corporate health insurance typically ends on your last day of employment or at the end of the month you leave. New country insurance often has a waiting period of 30–90 days. The gap between those two dates is real and most people discover it when they're already in the destination country without coverage.

Travel insurance for the transition period is not the same as health insurance — it covers emergencies but not routine care, pre-existing conditions, or the ongoing management of chronic conditions. If anyone in the family has a prescription, a specialist they see regularly, or a condition being managed, the coverage gap matters more, not less.

Life insurance is a related issue. Many life insurance policies are valid only in the country of issue or require notification of a permanent address change. Moving internationally without notifying your life insurer can create grounds for claim denial. Check the policy terms before you leave.

8. The Currency Exposure You're About to Accumulate

From the day you start earning in a new currency, you're holding FX risk somewhere. Your savings in the old currency are worth more or less depending on the exchange rate. Your expenses in the new currency fluctuate against whatever income you're converting. Your pension in one currency is your retirement income in another.

This doesn't require complex hedging. It requires awareness. A few practical things worth setting up before you arrive:

• A Wise account (or equivalent) for low-cost international transfers in both directions
• An understanding of your bank's international wire transfer fees and exchange rate markup — the typical bank markup is 2–4%, which compounds significantly on large or frequent transfers
• A view of which of your existing assets are in which currency and what your net exposure is to the old currency depreciating against the new one

The bigger issue tends to be property. If you own a home in your origin country, you now hold a significant asset denominated in a currency you're no longer earning in. Whether to sell before you leave or rent and maintain is a decision that has financial logic beyond "the market might go up." Think about what currency your future liquidity needs are denominated in.

The 90-Day Window

Most of this checklist is work that needs to happen in the 90 days before departure. The pension decisions, the brokerage account transfers, the tax residency timing, the equity compensation review — all of these have hard deadlines tied to your employment end date or departure date.

The relocation companies and HR teams that manage international moves are excellent at logistics. They know which shipping company to use and how to handle the work visa and where to put the family up while the apartment is being set up. None of them are equipped to give you financial advice, and most of them don't know to flag that you need it.

The COLA website tells you whether you'll feel rich or poor in the new city. It doesn't tell you that your unvested options are about to be allocated to the wrong jurisdiction, or that your brokerage account will be closed three months after you update your address, or that the pension you've been building for nine years has a transfer window that closes when you resign.

The financial architecture of your life was built for one country. Moving to another requires rebuilding parts of it deliberately. The ones you rebuild on purpose, before you leave, stay intact. The ones you discover after the fact cost more to fix than they would have cost to prevent.

For H-1B holders and NRIs navigating the India-US corridor, the full framework — 401K traditional vs. Roth decision for uncertain-timeline holders, PFIC exposure on Indian mutual funds, NRE account interest as US-taxable from day one — is in the H-1B financial playbook.
