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

Utah taxes your gains as ordinary income

There is no state equivalent of the federal preferential rate here — a long-term gain is charged at Utah's normal income brackets, exactly like wages. This is the common case, and it surprises people who assume the federal 15% carries over. Long-term capital gains are taxed as ordinary income at the flat 4.45%. Utah Code 59-10-104 imposes the tax on 'state taxable income', which begins from federal adjusted gross income and therefore already includes net capital gain; there is no preferential rate, no holding-period discount, and no general exclusion. The federal preferential long-term rate does NOT carry over, so a gain taxed at 15% federally is taxed at the full 4.45% by Utah. Utah does offer a narrow capital gain transaction credit for gains reinvested in a Utah small business, which is a targeted economic-development credit rather than a general capital gains break; its conditions were not confirmed from a primary source in this pass and no figure for it is recorded.
