Federal income tax for tax year 2027 (or 2026) on an income, using the IRS rate schedule: subtracts the standard or itemized deduction (with the age and blindness extra), applies the brackets, returns the bracket-by-bracket breakdown, marginal and average rate, optional long-term capital gains taxed at 0, 15 or 20 percent, and the tax on the same facts under the other year. Federal income tax only; no credits, self-employment tax, NIIT, AMT or state tax.
