Texas Supplemental Tax Regulations for Microsoft RSUs

Texas constitutionally prohibits personal state income tax on W-2 wages, supplemental RSU vests, and capital gains. Consequently, your brokerage sell-to-cover transaction withholds exclusively for Federal Supplemental Tax (22% up to $1M; 37% over $1M) and FICA (Social Security up to $184,500 and uncapped Medicare).

Texas Bracket Architecture: 0.00% state personal income tax and 0.00% state capital gains tax.

Texas Safe Harbor & Estimated Tax Vouchers (None (Federal Form 1040-ES only))

No state estimated tax filings exist in Texas. Tech employees must focus strictly on IRS Form 1040-ES safe-harbor thresholds (110% of prior-year federal tax or 90% of current-year federal tax).

Multi-State Relocation & Nonresident Sourcing Rules in Texas

Texas does not tax inbound or outbound equity grants. However, tech workers who transfer to Austin or Dallas from California or New York with unvested RSUs must track their exact relocation date, as their former state will claim source-income tax on the portion of each RSU tranche earned prior to the move.

Employer Stock Plan Specifics: Microsoft (Fidelity Investments (NetBenefits))

Microsoft combines a 4-year on-hire stock award schedule with 5-year quarterly vesting on annual stock refreshers awarded each August/September. Because annual refreshers stack across five overlapping grant years, long-tenured L63–L67 engineers experience steady, high-volume quarterly vests in February, May, August, and November—where Fidelity’s default 22% federal withholding falls 10% to 15% short of their true marginal tax bracket.

Withholding Election Guidance: Inside Fidelity NetBenefits (or Microsoft’s payroll portal), employees can either adjust their federal W-4 Step 4(c) "Extra Withholding" per paycheck or, where enabled for specific stock plan tranches, adjust supplemental withholding percentages in Fidelity prior to the quarterly record date. Adjusting W-4 withholding is often preferred because payroll withholdings are treated by the IRS as paid evenly across all four quarters.
