How it works

Note: No state personal income tax. RSU, ESPP, and ISO income are not taxed at the state level for residents — though multi-state allocation may still apply if you worked in another state during the vesting period.

RSU vests

Alaska does not impose a state income tax on wages, so RSU vests are not taxed at the state level for residents. Multi-state allocation rules may still apply if the vesting period spanned another state.

ESPP qualifying dispositions

No state-level ordinary income or capital-gain tax in Alaska.

ISO exercises

No state AMT or income-tax impact on ISO exercises in Alaska.

Frequently asked questions

Does Alaska have a state income tax on RSU vests?

No. Alaska has no broad state income tax for residents. Multi-state allocation may still apply if you worked in another state during the vesting period.

What supplemental withholding rate does Alaska use for RSUs and bonuses?

Alaska has no state income tax, so no state supplemental withholding applies.

Does Alaska have a state AMT for ISO exercises?

Alaska does not impose a personal AMT, so an ISO exercise typically does not trigger a state-level AMT bill (only federal AMT applies).

How does Alaska tax long-term capital gains?

No state-level capital-gains tax for residents.

Where is this information sourced?

Top marginal rates are from the Tax Foundation 2025 state individual income tax brackets summary. State supplemental rates are from the published guidance of each state's revenue department (linked above). Personal AMT status reflects 2025 legislation. Always confirm current-year rules with the Alaska Department of Revenue before making decisions.
