Typical comp shape
Sales engineers usually earn rsu + espp + commission. Common employers include Snowflake, Databricks, MongoDB, Confluent. Sales engineers earn both commission and full RSU grants, producing unusually high effective tax rates without planning.
What North Carolina changes
In North Carolina, every RSU vest, NSO exercise, and ESPP purchase carries 4.25% state tax on top of federal. For a senior sales engineer with $300k+ of equity income, the state layer routinely adds $25-45k to the annual bill.
Planning cadence
For a sales engineer in North Carolina, 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).
