How it works

Note: Minnesota retains a personal AMT (Schedule M1MT) at 6.75% that can apply to ISO exercises.

RSU vests

RSU vests are W-2 supplemental wages in Minnesota, withheld at the top marginal rate (9.85%) by default. Reconciled at filing against your actual marginal rate — same shortfall mechanics as federal.

ESPP qualifying dispositions

Minnesota taxes both the ordinary-income piece (the §423(c) discount) and the long-term capital gain at ordinary rates. Federal qualifying-disposition rules still split the gain into ordinary income and LTCG; state treatment is layered on top.

ISO exercises

Minnesota imposes a state-level AMT that can apply to ISO bargain element on top of federal AMT. Plan for additional state AMT in addition to the federal calculation.
