Typical comp shape
Principal engineers usually earn large rsu + psu grants. Common employers include Amazon, Microsoft, Oracle. Principal-level PSU tranches vest on multi-year performance windows, so cliff vests can concentrate income into one tax year.
What Alaska changes
Alaska has no wage income tax, which is structurally favorable for principal engineers with meaningful RSU comp. The savings vs a CA-resident colleague can be $30-60k per year at senior IC levels. That math is why Austin and Seattle are the two top relocation destinations for Bay Area tech workers.
Planning cadence
For a principal engineer in Alaska, 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). A move-out question — if you're considering leaving Alaska for a high-tax state, time it around vesting.
