How to Compare Equity Compensation Across States Before You Move

A move can change the tax result of the same stock award. You may leave California in June, have RSUs vest in September, and sell shares the next spring. As of 2026, 22 states have no meaningful nonresident filing threshold, while nine states do not tax wage or salary income at all, according to the Tax Foundation. In addition, the IRS allows a 22% federal withholding rate on certain supplemental wages, rising to 37% above $1 million. These differences make move timing and tax sourcing important when comparing equity compensation. That is why you should compare equity compensation before you move.

Start with five facts: the award type, the tax date, where you worked, where you live, and when you can use the cash. A low tax rate in the new state does not always erase tax tied to the old state.

This guide covers RSUs, NSOs, ISOs, ESPPs, and restricted stock. It also explains state sourcing, AMT, capital gains, tax basis, withholding, records, and local costs. Large awards can be complex, so use this guide for planning and ask a tax professional to review your facts.

 

Equity Compensation Basics

Equity pay can take several forms. RSUs promise shares or cash later. Stock options give you the right to buy shares at a set price. Restricted stock is already property, but you may lose it if vesting rules are not met. ESPP shares come from a company stock purchase plan.

First, do not treat every award as cash. A share grant can fall in value. An option can expire. Private shares may have no buyer. Also, a large paper gain can create tax before you have easy access to cash. Therefore, headline value is only the starting point.

To compare equity compensation, make a grant list. Record the grant date, shares or units, vest dates, strike price, end date, and current value. For private stock, note the latest value and sale limits. This gives you one clean set of facts for the state review.

Also, compare the quality of each award, not only its current dollar value. Two grants with the same headline value can differ sharply in liquidity, exercise deadlines, downside risk, and dependence on future share growth. A useful comparison should show value, access to cash, tax timing, and what must happen before the equity can be used.

A useful comparison also separates guaranteed value from potential upside. This keeps uncertain future stock growth from looking like cash already earned.

Federal Tax Timing When You Compare Equity Compensation

The federal tax date comes first. IRS Publication 525 explains that stock pay may be taxed at exercise, vesting, or sale. The rule depends on the award. States often start with that same income event, then decide how much belongs to their state.

RSUs are usually taxed at vesting, while NSOs are taxed at exercise. ISOs may trigger AMT, and restricted stock is generally taxed at vesting unless an 83(b) election applies.

Therefore, do not use one tax rule for all grants. Map each grant to its own tax date. Then add the state where you lived and the states where you worked. The table below gives a simple guide.

For planning, compare equity compensation by mapping when taxes may arise, when cash is needed, and when shares can be sold. This helps reveal which awards could create a real cash need around the move.

This timing map also helps you spot years with several taxable events at once, which can create a much larger cash need.

Award	Main tax point	Wage or ordinary income	Later sale	Move issue
RSUs	Vest/settlement	Value at vest is usually wages	Gain/loss from basis	Old state may claim a service-period share
NSOs	Exercise	Market value minus strike	Post-exercise gain/loss	Old state may tax part of exercise spread
ISOs	Exercise can affect AMT	No regular income at exercise if rules apply	Sale can be capital gain or part ordinary	Exercise and sale may occur in different states
ESPP	Sale/disposition	Discount portion may be ordinary income	Balance may be capital gain/loss	Purchase and sale can straddle the move
Restricted stock	Vesting or 83(b) date	Value less amount paid	Later gain/loss	83(b) can move the tax date earlier

 

Residency and State Sourcing

Residency and sourcing answer two different tax questions. Your home state may tax income because you live there. A former state may tax income because the stock pay came from work done there. As a result, the same vest or exercise can involve more than one state.

California is a clear example. FTB Publication 1100 says California can tax wage income from nonstatutory stock options when it comes from California services. This can apply even if you are a nonresident when you exercise. New York also uses special allocation rules for stock pay. Its Form IT-203 instructions point filers to Form IT-203-F for stock options, restricted stock, and stock appreciation rights.

Therefore, track the move date and the work period as separate facts. Keep a simple workday log by state. Also keep proof of your new home and domicile. This guide to state tax residency after moving explains day counts, address changes, payroll records, and other proof that can support a move.

In addition, when you compare equity compensation, consider where the award was earned and where the taxable event occurs.

Payroll may report state wages based on work history, while a resident return may treat the same income differently. Good records help tie each grant to its service period, not only the move date.

If two states may claim the same income, flag that amount separately so credits, allocation rules, and filing duties can be reviewed clearly.

 

RSUs Across State Lines

RSUs look simple because there is no strike price. Suppose 500 units vest when the stock is worth $80. The gross value is $40,000. That amount is usually treated as wages. After the shares are delivered, later price changes are tracked from your tax basis.

However, the state part can be harder. A vest after your move may still be partly tied to work in the old state. New York guidance on RSUs shows that resident status at the tax date can matter. Service history can matter too. Therefore, model each vest on its own when a grant spans two states.

To compare equity compensation for RSUs, track gross vest value, shares withheld, shares received, state wages, and tax basis. Also run a low, base, and high stock price. This keeps you from treating future vests as fixed cash when the share price can still move.

For RSUs, build several share-price scenarios around the expected vest date. A higher price raises both gross value and vest-date tax, while a lower price reduces them. Also track shares withheld for tax and shares left after settlement. This gives a clearer view of spendable value than multiplying units by today’s share price.

For each vest, record the service period tied to the award. That detail can matter when more than one state has a tax claim.

 

Stock Options and AMT

NSOs and ISOs need different math. With an NSO, the spread at exercise is usually wage income. If 2,000 options have a $20 strike and the stock is worth $50, the spread is $60,000. That can create tax and a large cash need on the same day.

ISOs can create AMT even when no regular income tax is due at exercise. The IRS instructions for Form 6251 explain that the difference between market value and the exercise price generally enters the AMT calculation. Also, your AMT basis can differ from your regular tax basis. Keep both records.

When you compare equity compensation for options, include strike cost, tax, AMT, sale limits, and the time left before expiry. Private options need an extra discount for lack of cash access. Consequently, an option with a large paper gain may still have weak real value if exercise is costly or the shares cannot be sold.

Option comparisons should include the cost of waiting. A grant with years left before expiration offers more flexibility than one near its deadline. Yet exercising early can create tax or AMT exposure before the shares are sold. Compare exercise cost, potential tax, remaining term, liquidity, and expected upside together.

For options, compare exercise-now, exercise-later, and no-exercise cases. The best choice can change as share price and liquidity change.

 

ESPPs and Restricted Stock

ESPP shares can create both ordinary income and capital gain. The split depends on plan rules and how long you hold the shares. IRS Topic 427 notes that qualified ESPP options are statutory options. Form 3922 can also give key dates and values for tax reporting.

Restricted stock works in a different way. It is property, so tax usually waits until the stock is vested. However, a Section 83(b) election can move the tax date to the transfer date. The IRS provides Form 15620 for this election. It generally must be filed within 30 days after the property transfer.

When you compare equity compensation, remember that a move can fall between purchase, vesting, and sale. Therefore, keep each event separate. For ESPP shares, save purchase and sale records. For restricted stock, keep the grant, vesting terms, and any 83(b) filing. These records help separate compensation income from later investment gains.

With ESPPs and restricted stock, holding periods need their own line in the comparison. A sale soon after purchase or vesting may have a different tax result from a later sale. If a move falls between those dates, track each purchase, vest, election, and sale separately so basis and holding periods stay clear.

These awards also benefit from a sale-date plan, because holding-period rules can change how much income is ordinary versus capital gain.

 

Compare Equity Compensation and Capital Gains After the Move

After compensation tax has been recognized, a later sale creates a gain or loss. In simple terms, gain equals sale price minus adjusted tax basis. Basis is important because part of the stock value may already have been taxed as wages. If basis is wrong, the return can show too much gain.

High earners may also face the 3.8% Net Investment Income Tax on some investment income, including capital gains, above set income limits. Therefore, keep wage tax and investment tax in separate rows in your model. This makes the state result much easier to read.

States treat investment gains in different ways. Some tax them through the normal state income tax. Some do not have a broad personal income tax. Credits for tax paid to another state may help in some cases, but the rules do not always match. Large sales across two states deserve a careful tax review.

Next, when you compare equity compensation, separate compensation income from later investment performance. Once tax is paid and basis is set, future gains or losses should be measured from that basis. This helps show what came from compensation, market growth, and the amount left after tax.

Keep sale decisions separate from vest decisions. A move may change the state result on later gains even when compensation tax is already fixed.

State Tax Differences When You Compare Equity Compensation

The state rate matters, but it does not answer the sourcing question. The Tax Foundation 2026 state tax review lists eight states with no individual income tax. California has a top marginal rate of 13.3% in 2026. Still, a move to a low-tax state does not wipe out old-state source income.

Massachusetts gives another useful example. Its nonresident tax rule says that pay for services performed in Massachusetts is Massachusetts-source income. It also has a rule for nonqualified stock options tied to Massachusetts work. By contrast, Texas and Florida do not have a broad tax on wage income.

Washington has no broad wage income tax in 2026, but it does tax certain long-term gains. Its tiered capital gains tax is 7% on the first $1 million of taxable Washington capital gains and 9.9% above that amount, after applicable deductions and rules. For real state-to-state examples, compare moving from San Francisco to Denver, moving from Los Angeles to Dallas, and moving from Boston to Austin. These guides show how taxes and local costs can reshape purchasing power after a move.

Also look beyond the headline state income-tax rate. Local taxes, capital-gain rules, deductions, credits for taxes paid elsewhere, and sourcing rules can all change the result. If Arizona is on your shortlist, this guide to relocating to Arizona adds another real-world view of how taxes and everyday costs can change a household budget. Model the events you expect, such as an RSU vest, option exercise, or stock sale, instead of ranking states by one tax percentage.

A strong comparison uses effective tax cost, not only the top rate. Your actual result depends on income level and applicable state rules.

 

Moving Dates, Records, and Withholding

A clean timeline can save hours later. Record your move date, every vest, every exercise, every ESPP purchase, and every sale. Next, add workdays by state for each grant period. Travel back to the old state can matter too, so keep the log even after the move.

Also, withholding is only a prepayment. It may not equal final tax. Review W-2 state wages, vesting statements, exercise forms, Forms 3921 and 3922, Forms 1099-B, and broker basis records. In addition, keep the stock plan and grant terms. They show the dates and service rules behind the award.

Moving costs should stay outside the stock tax formula, but they still affect cash needs. The guide to relocation expenses and taxes covers move-year tax issues. The cost of moving explains common costs beyond the first quote, while this breakdown of predictable moving-expense patterns helps separate baseline costs from move-specific surprises. Use these costs when deciding how much cash to keep before an option exercise or stock sale.

Before the move, create one folder for every equity document and keep copies outside the employer portal. Save grant agreements, vesting schedules, trade confirmations, payroll statements, tax forms, and proof of the move date.

Then reconcile them after year-end so state wage or withholding differences are easier to spot and question.

Good records also help you compare equity compensation accurately, challenge incorrect state wage reporting, and explain allocations if tax notices arrive after the move.

 

A Practical Equity Comparison Method

Use one sheet for all grants. First, list the shares that may vest, be exercised, or be sold in the next 12 to 24 months. Then run three share prices. For each event, show gross value, federal tax, old-state source tax, new-state tax, and cash needed. This keeps the math consistent.

Next, split the result into locked, liquid, and at-risk value. Locked value is stock you cannot use yet. Liquid value is cash or shares you can sell after tax and limits. At-risk value is still exposed to price changes, AMT, expiry, or a lack of buyers. Therefore, the best number is usable after-tax value, not paper value.

Finally, add local buying power. The BEA Regional Price Parities show price gaps across states and metro areas. The relocation calculator can help estimate destination costs. Also, lower-cost cities can hide expenses beyond rent, so compare the full local budget before treating a tax saving as a net gain. Add this layer last. That way, you can compare equity compensation first, then see what the after-tax value may buy in the new location.

A final scorecard can make the result easier to use. For each state scenario, show estimated after-tax value, cash needed before liquidity, shares remaining, concentration risk, and local buying power.

If housing is one of the biggest destination changes, compare the cost of renting versus owning before converting after-tax equity into a home budget. Add a note for items that need professional review. This keeps tax, timing, risk, and real-world value in one practical comparison.

Once the numbers are side by side, focus on after-tax, usable value. That is the clearest basis for comparing equity across locations.

Frequently Asked Questions (FAQ) About Compare Equity Compensation

 

1. Can you sell your old state tax RSUs after your move?

Yes, it can in some cases. A former state may tax part of the vesting if the award was earned through work performed there. The exact share depends on the state rules and the service period.

 

2. Are RSUs taxed at grant or vest?

RSUs are usually not taxed at grant. In a typical plan, tax applies when the units vest and settle into shares or cash. Later price changes are then measured from the tax basis.

 

3. What is the main tax risk with ISOs before a move?

AMT is a major risk. An ISO exercise can create an AMT adjustment even with no regular tax at exercise. Model the spread, cash need, and possible sale timing before exercising a large block.

 

4. Does moving to Texas or Florida remove tax on old stock grants?

Not always. Those states have no broad individual wage income tax, but your old state may still tax stock pay tied to work performed there before the move.

 

5. What records should you keep for multi-state equity?

To compare equity compensation accurately, keep grant terms, vesting and exercise records, W-2s, Forms 3921 and 3922, 1099-B forms, broker basis data, trade records, workday logs, and proof of the move date.

 

6. Should cost of living be part of the equity comparison?

Yes, but add it after the tax model. First find the likely after-tax stock value. Then compare what that value can buy in the new state or metro area.

 

Final Note

To compare equity compensation across states, start with the award and tax date. Then add residency and state sourcing. RSUs, NSOs, ISOs, ESPPs, and restricted stock can all create tax at different times. A move changes where you live, but it may not end the old state’s claim on pay earned there. Use a grant-by-grant timeline. Keep workday records and tax basis. Run more than one share price. Also separate wage tax from later capital-gain tax.

This gives you a much clearer view of what the stock may be worth after tax and when you can use the money.
