If you have Restricted Stock Units (RSUs) and you’re relocating from New York to Texas or another state, the timing of your move relative to your vesting dates can have massive tax implications. Understanding how states allocate RSU income can save you tens of thousands of dollars.
How RSUs Are Taxed
RSUs are taxed as ordinary income when they vest. The value of the shares on the vesting date is treated as compensation, just like your salary. This income is subject to:
- Federal income tax
- State income tax (based on where you earned the compensation)
- FICA taxes (Social Security and Medicare)
The State Allocation Problem
When you work in multiple states during the period between grant and vesting, states use allocation formulas to determine how much of the RSU income is taxable in each state. New York’s allocation formula is particularly aggressive.
New York’s Allocation Method
New York allocates RSU income based on the ratio of:
- Days you worked in New York between grant and vest
- Total days worked between grant and vest
Formula: (NY workdays / Total workdays) × RSU value at vesting = NY taxable income
Example:
- RSU grant date: January 1, 2023
- Vesting date: January 1, 2026 (3-year cliff vesting)
- Total workdays between grant and vest: 750 days
- NY workdays during that period: 500 days
- You moved to Texas on July 1, 2024
- RSU value at vesting: $100,000
NY allocation: (500 NY days / 750 total days) × $100,000 = $66,667 taxable to NY
Even though you were a Texas resident when the RSUs vested, New York taxes $66,667 of the income because you earned it while working in New York.
Texas allocation: Texas has no income tax, so the remaining $33,333 is not taxed by any state (though it’s still subject to federal tax).
Timing Strategies
Strategy 1: Move Before Grant Date
If you move to Texas before RSUs are granted, 100% of the income will be allocated to Texas (zero state tax).
Best for: Employees who haven’t received grants yet or who can negotiate new grants after relocating.
Strategy 2: Accelerate Vesting Before Moving
Some employers allow you to accelerate vesting in connection with relocation. If you can vest your RSUs while still a New York resident and then move, you:
- Pay NY tax on the vested amount
- But future grants will be 100% allocated to Texas
Best for: Employees with significant unvested RSUs who can negotiate acceleration.
Strategy 3: Time Your Move Around Vesting Dates
If you have RSUs vesting quarterly or annually, consider moving immediately after a vesting date rather than before. This maximizes the portion allocated to your new state.
Example:
- RSUs vest quarterly (March, June, September, December)
- If you move in July, the September and December vests will have more days allocated to Texas
- If you move in May, you’d have more NY allocation
Strategy 4: Negotiate New Grants Post-Move
If you’re relocating for a new job or your employer is relocating you, negotiate for:
- Cancellation of unvested NY-granted RSUs
- New grants issued after you establish Texas residency
- Sign-on bonus to compensate for forfeited unvested RSUs
The “Convenience of the Employer” Rule
New York has a “convenience of the employer” rule that can complicate RSU allocation for remote workers. If you:
- Work remotely from Texas
- For a NY-based employer
- For your own convenience (not employer’s requirement)
New York may argue that your compensation should be allocated to NY even though you’re physically in Texas. This rule is controversial and subject to ongoing litigation, but it creates audit risk.
Multi-State Allocation
If you work in multiple states during the grant-to-vest period, each state may claim a portion of the RSU income:
Example:
- Grant date: Jan 1, 2023 (working in NY)
- Moved to California: July 1, 2024
- Moved to Texas: July 1, 2025
- Vest date: Jan 1, 2026
- Total workdays: 750
- NY workdays: 375
- CA workdays: 250
- TX workdays: 125
- RSU value: $100,000
Allocation:
- NY: (375/750) × $100,000 = $50,000
- CA: (250/750) × $100,000 = $33,333
- TX: (125/750) × $100,000 = $16,667 (not taxed)
You’d owe NY tax on $50,000 and CA tax on $33,333, even though you were a Texas resident when the RSUs vested.
Withholding Issues
Your employer’s payroll system may not correctly withhold for multiple states. Common problems:
- Employer withholds only for your current state of residence
- Underwithholding for NY creates a surprise tax bill
- You may need to make estimated tax payments to NY
Documentation Requirements
To support your allocation, maintain:
- Employment records showing work location each day
- VPN logs or office access records
- Travel itineraries
- Calendar showing where you worked
- Employer letters confirming work location
Performance-Based RSUs
If your RSUs vest based on performance metrics rather than time, the allocation may be different. Some states allocate based on the performance period rather than the grant-to-vest period.
Reporting on Your Tax Return
When you file your tax returns:
- Report the full RSU income on your federal return
- Allocate the income among states on your state returns
- NY nonresident return: Report only the NY-allocated portion
- Claim credit on your resident state return for taxes paid to other states (if applicable)
Common Mistakes
Taxpayers often:
- Assume all RSU income is taxed in their state of residence at vesting
- Fail to file nonresident returns in states where they previously worked
- Don’t maintain documentation supporting their allocation
- Rely on employer withholding without verifying accuracy
