Before returning to Taiwan, make sure you can still access U.S. bank, investment and retirement accounts from abroad. Organize tax records, update contact details and beneficiaries, and review withdrawal rules before moving money.
TSMC-specific foundation
Use the final U.S. months to protect records and account access
Returning to Taiwan can end U.S. employment, health coverage and payroll while changing access to banks, brokerages and retirement plans. The most valuable work happens before the U.S. address and mobile number become unreliable. Final pay, bonus eligibility, the 401(k), HSA, insurance and relocation repayment terms may all follow different dates.
Create a deadline list for final pay, bonus eligibility, benefits, 401(k), HSA, bank accounts, brokerage accounts, lease obligations and moving logistics.
Update secure access methods before a U.S. mobile number or mailing address becomes unreliable. Document provider policies on foreign addresses.
A former employee may be able to keep a qualifying balance in the TSMC plan, roll to an eligible U.S. account or take a distribution. Each path has different tax, access and withholding consequences.
IRS guidance says distributions to foreign payees can require withholding unless proper documentation supports a different treatment. Plan before the first distribution is requested.
How the pieces interact
Sequence taxes, benefits and address changes before departure
A foreign address can change provider services and retirement-distribution withholding. The employee may still have U.S. filing obligations after departure and may need maximum Taiwan account values for the final U.S. resident year. Rushing to close accounts can create taxable sales or distributions without solving those reporting requirements.
Keep travel dates, employment dates, pay statements, relocation records and account statements. U.S. residency, foreign account reporting and Arizona filing status may all depend on facts.
Ask the tax professional which forms, statements and maximum account values they need before the move.
The advisor can organize accounts, investment policy, cash needs and distribution choices. The tax professional determines reporting, residency and filing positions.
For a TSMC employee, the best result usually comes from a shared timeline rather than separate conversations after deadlines pass.
Put the guide to work
A 90-day TSMC Arizona departure plan
Create a departure calendar, download records, update secure authentication and obtain written provider policies. Decide account changes only after the final U.S. tax status, Taiwan arrival plan and professional responsibilities are clear.
Use the sequence below as preparation, not as individualized advice. Current TSMC documents control employer benefits, and qualified tax or legal professionals should confirm decisions in their areas.
- Create a 90-day benefits and payment calendar
- Preserve W-2, 1099, payroll and travel records
- Confirm 401(k), HSA, bank and brokerage address policies
- Update beneficiaries and trusted contacts
- Schedule coordinated U.S. and Taiwan tax reviews
- 401(k) and IRA access
- Brokerage foreign-address policy
- Banking and credit cards
- Two-factor authentication
