What the calculator leaves out

Farm assets get a 60% exclusion.
Long-term gain on an investment in a qualified Wisconsin business, held at least five years, can be excluded in full.

Federal tax stacks the gain on wages after the 2026 standard deduction, taxes a long-term gain at the long-term capital gains rates and a short-term gain at the ordinary brackets, and adds the net investment income tax. The gain is the only investment income. Capital losses and carryovers, qualified dividends, the collectibles and section 1250 rates, the alternative minimum tax and credits are left out; enter a home sale's gain after any federal exclusion.
