Pre-Departure Checklist: What to Confirm Before Closing Your US Bank, Brokerage, and 401(k) Accounts

/ Blog (EN), Visa, Residency & Repatriation / By

Once a return to Japan is decided, it’s easy to get absorbed in packing and moving logistics — but winding down U.S. bank accounts, brokerage accounts, and 401(k)s is exactly the kind of thing that becomes tax-disadvantageous if you scramble to handle it at the last minute. Once you’re back in Japan as a nonresident alien, your options narrow considerably, so it’s important to wrap up as much as possible while you’re still a U.S. resident. This article covers the financial-account checkpoints to confirm before you leave.

Bank Accounts: Your Options Narrow After You Leave

Many U.S. banks will freeze or forcibly close an account once they detect the account holder’s address has changed to a foreign country (particularly certain countries, including Japan, for KYC/compliance reasons). If this happens after you’ve returned, visiting a U.S. bank branch in person from Japan is essentially impossible, risking your funds being locked up for a long time. Before leaving, confirm the following:

  • Check directly with your bank whether it will let you keep the account open once you’re no longer a U.S. resident
  • If not, either close the account before updating your address, or complete an international transfer to a Japanese bank account first
  • Once you return to Japan and become a nonresident alien for U.S. tax purposes, FBAR and Form 8938 (FATCA) reporting obligations generally no longer apply (they do continue for U.S. citizens and green card holders). On the Japanese side, however, if your total overseas assets exceed 50 million yen as of December 31, you must file Japan’s Overseas Assets Report (kokugai zaisan chosho)

Brokerage Accounts: Consider Moving to a Broker That Serves Nonresidents

For regulatory reasons, many major U.S. brokerages won’t let you keep an account once your address changes to a foreign country, including Japan. If you leave without addressing this, the brokerage may unilaterally force-liquidate your positions — potentially triggering capital gains at a time you didn’t choose. Once your return is decided, consider one of the following:

  • Transfer assets, while still a U.S. resident, to a brokerage that supports nonresident alien (NRA) accounts (e.g., one with an international accounts division)
  • Sort out which holdings you’re comfortable selling and which you want to keep, and liquidate on a schedule that manages the tax impact
  • Get a clear picture of unrealized gains/losses in your taxable brokerage account ahead of time and estimate the impact on your tax return for the year you leave

401(k): Three Decisions to Make Before You Leave

For a 401(k) with a former employer, you generally have three options:

  1. Leave it in the former employer’s plan: most plans allow this after you leave the job, but distributions after you become a nonresident are generally subject to 30% withholding (which may be reduced under the US-Japan tax treaty).
  2. Roll it over into an IRA: opening a new IRA as a nonresident after you’ve returned to Japan is often difficult due to brokerage restrictions, so it’s safer to complete the rollover itself while you’re still a U.S. resident.
  3. Cash it out (early withdrawal): withdrawing before age 59 1/2 generally triggers a 10% early withdrawal penalty on top of federal and state income tax, making this the most heavily taxed option.

Whichever option you choose, securing a brokerage that can open or maintain the account while you’re still a U.S. resident is the single most important step to avoid narrowing your options after you leave.

Other Things Worth Wrapping Up Before You Leave

  • Pay off and close unneeded credit cards (watch out especially for cards with recurring annual fees)
  • Confirm you’ll reliably receive tax documents like Form 1099 — set up a forwarding address or enable online statements
  • Handle address-related items that affect state tax residency determinations, such as surrendering your driver’s license and canceling voter registration
  • Confirm whether you need a Sailing Permit (Certificate of Compliance) — covered in detail in a separate article

Frequently Asked Questions

Q: Can I keep my U.S. bank account after returning to Japan?

A: It depends on the bank and branch. Some online banks and banks with strong international operations allow keeping an account with a foreign address, but many regional and major banks often ask you to close the account once your address changes. Always confirm with your specific bank before leaving.

Q: Can I do the IRA rollover after I’ve already returned to Japan?

A: It’s not technically prohibited, but most brokerages won’t open new accounts for a nonresident address, so in practice we strongly recommend completing the rollover while you’re still a U.S. resident, before you leave.

Summary

Your options for U.S. bank accounts, brokerage accounts, and 401(k)s narrow considerably the moment you become a nonresident. Don’t put this off just because you haven’t registered a Japanese address yet — confirm each institution’s policy as soon as your return is decided, and complete any transfers, rollovers, or closures while you’re still a U.S. resident. That’s the best way to avoid trouble after you’ve left.
