What a taxable index-fund account is actually worth after expense-ratio drag and after Minnesota takes its share of the gain — which, in most states, is not at the federal preferential rate.

Minnesota taxes your gains as ordinary income

There is no state equivalent of the federal preferential rate here — a long-term gain is charged at Minnesota's normal income brackets, exactly like wages. This is the common case, and it surprises people who assume the federal 15% carries over. No preferential rate and no exclusion. Because Minnesota taxable income begins from federal AGI, capital gains and qualified dividends are fully included and taxed at the ordinary 5.35% to 9.85% bracket rates. Separately, Minn. Stat. 290.033 imposes a 1% net investment income tax on such income above $1,000,000, which this record does not encode: the threshold is a single figure that does not vary by filing status, is not inflation-indexed, applies to individuals, estates and trusts, excludes gain on class 2a agricultural property and interest on U.S. obligations, and cannot be offset by the credit for taxes paid to other states.
