Is Your TSMC Relocation Package Taxable? Questions to Ask Before Moving

TSMC-specific foundation

Break the TSMC relocation package into taxable components

For 2026, federal law permanently eliminates the qualified moving-expense reimbursement exclusion for most civilian employees, with narrow exceptions for qualifying military and intelligence-community moves. TSMC relocation payments, reimbursements, vendor-paid services and tax gross-ups can therefore appear differently in payroll, but an employee should not assume that a company-paid item is tax-free.

Create a line-item list for signing or relocation bonuses, household-goods services, temporary housing, travel, lease costs, home-sale assistance and tax gross-ups. Record who pays each vendor and what the agreement says about tax reporting.

Keep receipts even when a vendor is paid directly. Payroll treatment and employer reporting can differ from the employee’s intuitive idea of reimbursement.

For 2026, IRS Publication 15-B says federal law permanently eliminates the qualified moving-expense reimbursement exclusion for most civilian employees. Narrow exceptions apply to qualifying active-duty Armed Forces moves and certain intelligence-community moves. The exact payment and payroll reporting still determine what appears in taxable wages.

A gross-up can help cover tax but is itself part of the compensation calculation. Reconcile the relocation statement with pay records and Form W-2.

How the pieces interact

Model the move-year tax and the repayment clause together

A gross-up is additional compensation intended to offset some tax; it may not equal the household's final federal and Arizona result and may itself be part of taxable wages. A repayment clause creates another risk: leaving early may require repayment of gross amounts even though taxes were withheld. The cash reserve should reflect the written clawback, not merely the net relocation cash received.

Relocation agreements often require repayment if the employee leaves within a stated period. Confirm whether repayment declines over time, which events trigger it and whether taxes or gross-ups are included.

If repayment occurs in a later tax year than the original wage inclusion, the tax mechanics can be complex. Obtain tax advice before paying or netting amounts.

Arizona requires new employees subject to state withholding to complete Form A-4. A large relocation payment, spouse income or part-year residency can make the default percentage a weak estimate.

An advisor familiar with TSMC Arizona can organize the cash-flow plan while a tax professional reviews wage reporting and move-year residency.

Put the guide to work

Build a relocation ledger from agreement to Form W-2

Track each benefit category, vendor payment, reimbursement, gross-up and withholding amount. Reconcile the relocation statement with pay records and Form W-2, and keep receipts and the signed agreement until tax and repayment periods have passed.

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.

• List every cash and vendor-paid relocation benefit
• Mark expected payroll and tax treatment
• Understand the gross-up formula and its limits
• Model the early-departure repayment obligation
• Reconcile actual payroll reporting with a tax professional
