State tax on RSUs when you move states

Can you dodge state tax on your RSUs by moving to Texas or Florida before they vest? Partly, and the part you cannot is the part people forget. The state where you earned the grant gets to tax the share of the income that was earned while you lived and worked there, even after you have left and changed your driver’s license.

RSU income is earned over time, not in a day

A grant vests over years. States look at that whole stretch, the period you were working toward the shares, and they tax the fraction that was earned inside their borders. The common rule is a workday count: divide the days you worked in the state during the vesting period by the total workdays in that period, and that fraction of the vesting income belongs to the state.

So if you spent the first three years of a four-year vest in a high-tax state and the last year somewhere with no income tax, a big chunk of that income still traces back to the high-tax state. The vest happens on one date. The earning happened over years, and your old state remembers.

The wage piece follows you; the gain piece usually does not

Split your RSU into its two tax events and the relocation answer gets clearer.

The vesting value is compensation, wages for work performed. High-tax states like California and New York source that to the workdays you put in there and tax a former resident on that slice when it is recognized. Leaving does not wipe it out.

The capital gain after vesting is different. That is investment income on intangible property, and it is generally sourced to where you live when you sell, not where you worked. A former California resident who has truly moved to a no-tax state and then sells the shares generally owes no California tax on that post-vesting gain. Same baseline in New York for a pure capital gain. The wages slice can chase you. The gain slice usually does not. This is the same split that runs through how RSUs are taxed.

The hidden price of timing a move around equity

Here is where the tax tail tries to wag the dog. People hear “move before it vests and save the tax” and start planning a cross-country move around a vesting calendar. The math rarely justifies it on its own.

You only shelter the income earned after you have genuinely established residency in the new state, and states scrutinize a convenient move hard: where you actually sleep, where your family is, where your life moved. A half-hearted move that does not hold up just buys you an audit instead of a tax cut. Move for your life, your job, your family, and capture the tax benefit as a bonus. Do not uproot for the tax and hope the facts cooperate.

I already moved. How do I figure out what each state can tax?

Pull the period each grant was vesting and count your workdays in each state across that window. The compensation that traces to your old state’s workdays is taxable there when it vests; the rest follows your new residency. The capital gain after vesting generally follows where you live at sale. Because every state writes its own version of these rules, and because a few states reach further than others, this is a spot where an hour with someone who does it for a living pays for itself. Talk it through before you file a multi-state return with equity in it.

What this means for you

Stop thinking a move makes RSUs tax-free. The wages slice is sourced to where you worked while you earned it, and high-tax states will collect their share even after you leave. The gain slice generally follows your new home. If a move is happening anyway, time it so more of the vesting falls after you have truly settled, and document the move so it holds. Just do not let the tax savings drive a decision this big. The income remembers where it was earned, and so does the state.
