Typical comp shape
Technical writers usually earn rsu (smaller grants). Common employers include Stripe, GitHub, Atlassian. Grant sizes run 40-50% below engineering at the same level, so ESPP participation often becomes the largest equity lever.
What Mississippi changes
In Mississippi, every RSU vest, NSO exercise, and ESPP purchase carries 4.4% state tax on top of federal. For a senior technical writer with $300k+ of equity income, the state layer routinely adds $25-45k to the annual bill.
Planning cadence
For a technical writer in Mississippi, the three planning windows are: after each RSU vest (withholding check and sell-vs-hold), before any ISO exercise (AMT model at federal only), and in Q4 (estimated tax top-up to clear the safe harbor).
