Retiring From TSMC Arizona: A U.S. Account and Benefits Checklist

Retirement date

Pin down final pay, bonuses and benefit-end dates first

Your retirement plan begins with the current 401(k), the date active health coverage ends, your variable compensation and any relocation or return-service obligations still attached to you. It may also span U.S. Social Security, Taiwan pension or labor-retirement interests and accounts in both countries.

Public recruiting materials confirm the broad benefit categories; your employment and incentive documents set the specifics — final wages, unused-leave treatment, bonus eligibility and when coverage ends. Do not assume retirement and resignation receive identical treatment.

Create a deadline list covering benefit elections, stock or incentive arrangements, the 401(k), insurance and company property. Then translate those dates into monthly income.

Income plan

Replace the paycheck with a coordinated monthly system

List Social Security, pension interests from any country or prior employer, 401(k) withdrawals, IRA distributions, taxable investments and cash reserves — then model federal and Arizona tax withholding on top.

Your first retirement year can still contain wages and bonuses, while the next may run lower. Compare both before scheduling conversions or large sales, and before settling where the 401(k) itself should live.

Stay, roll or distribute — measured against actual plan terms

Review the investments, fees, withdrawal flexibility, loans, beneficiary rules and whether your account can remain after retirement. A direct rollover may preserve tax deferral, but an IRA is not automatically the best destination.

Here is how residence reshapes the choice: an IRA may offer broad U.S. investment flexibility, yet a provider may restrict services to Taiwan residents. Leaving money in the employer plan may preserve institutional features but limit distributions, while a cash distribution may trigger tax and withholding. If Taiwan is a possibility, compare the retirement year and the first full year afterward under both a U.S.-resident and a Taiwan-resident scenario — with each provider’s foreign-address policy and future distribution withholding in the file.

Health and estate planning

Coordinate coverage and documents across jurisdictions

Bridge your employer coverage to Medicare, a spouse’s plan, COBRA or another available option based on your age and residence. Include dental, vision, the HSA and any travel or international coverage needs in the same review.

Review beneficiaries, powers of attorney and estate documents with professionals who understand where you — and your assets — will be located.

Decide the where first

A retirement plan that works in Arizona — and in Taiwan

Before any money moves, you should know where you will live, how health care will work, which currency funds your spending and how each U.S. provider handles your future address. Tax and estate questions that cross jurisdictions belong with qualified U.S. and Taiwan professionals.

Read this as preparation, not as individualized advice — current TSMC Arizona documents control your benefits, and cross-border professionals should confirm the tax picture before distributions begin.

• Confirm your benefit and insurance end dates
• List your U.S. and Taiwan retirement-income sources
• Compare keeping the 401(k), a direct rollover and distributions
• Verify each provider’s foreign-address policy before changing residence
• Build two years of cash-flow and withholding estimates
