What changed for 2027: tax brackets, limits, Social Security and Medicare

The IRS, the Social Security Administration and HHS have published most of the 2027 figures that matter for retirement planning. Below, every published change from 2026 is in one table, followed by what the new tax tables do to the federal income tax of four sample retired households. Figures that are not yet out are marked “not yet published” in the table. We do not estimate them.

Every published change, 2026 to 2027

Published 2027 figures beside 2026. “Not yet published” rows show the 2026 figure only. Each row cites the source of its 2027 figure (or, while pending, of its 2026 figure) after the label, and the 2026 source after the 2026 figure when it differs.

The tax brackets moved too. Each bracket’s upper edge rose for every filing status; the full ranges are on the 2027 tax brackets page, and the limits, Medicare and ACA figures each have their own page: contribution limits, IRMAA tiers and ACA numbers. All of it on one printable page: 2027 key retirement numbers.

What it means in dollars: four sample households

Each household below is run through the same federal tax function the simulator uses, once with the 2026 tables[2] and once with the 2027 tables[1]. Income is held at the same nominal dollars in both years, so the difference is the effect of the new brackets, deductions and capital-gains thresholds alone.

Federal income tax before credits, 2026 vs 2027 tables, same nominal income.

A married couple filing jointly, both 67, with $40,000 of Social Security and $50,000 of IRA and pension income ($90,000 in all).

A married couple filing jointly, both 67, with $48,000 of Social Security, $92,000 of IRA and pension income and $20,000 of qualified dividends and long-term gains ($160,000 in all).

$40,800 of the $48,000 in benefits is taxable in both years: the Social Security thresholds are fixed in the statute and not indexed[20]. AGI of $152,800 is above the $150,000 line, so each senior deduction shrinks by 6 cents per dollar over it, to $5,832 per person. The $20,000 of gains stacks on top of $84,536 of taxable ordinary income in 2027 ($85,636 in 2026), so the higher 2027 0% threshold shelters more of it. The 2027 change in federal tax: −$793.

A married couple filing jointly, both 60, with $100,000 of IRA and pension income and $20,000 of qualified dividends and long-term gains ($120,000 in all), not yet on Social Security or Medicare.

The $20,000 of gains stacks on top of $66,800 of taxable ordinary income in 2027 ($67,800 in 2026). The total stays under the 0% ceiling in both years, so all of the gains are taxed at 0% either way. Before Medicare this couple would buy marketplace coverage, but with $120,000 of MAGI they are above the 400% line for a household of two in both years ($84,600 for 2026 coverage, $86,560 for 2027), so no premium tax credit either way. The 2027 change in federal tax: −$136.

Assumptions

  • Incomes are held equal in nominal dollars in both years; nothing is inflated or projected.
  • Federal income tax only, before credits, computed with the rate schedules (the IRS tax table rounds lower incomes into bands, so a filed return can differ by a few dollars). No state tax.
  • Everyone takes the standard deduction, plus the age-65 additions and the senior deduction where they qualify (ages are at the end of the year). IRA and pension income is fully taxable.
  • The taxable part of Social Security follows the IRS Publication 915 worksheet, counting all other income including gains[20].
  • No household reaches the 3.8% net investment income tax.

The simulator still uses 2026 rules. Its tax engine is built on the 2026 figures and indexes them along each simulated inflation path; the 2027 figures on this page are published for reference and will become the simulator’s base when it rolls over to 2027.

Until it rolls over, a plan you run there prices 2027 and later years with the 2026 tables indexed by each path’s simulated inflation, not with the 2027 figures above. The Roth conversion calculator uses the same tax function for a single year, and how capital gains stack explains the 0% threshold effect in the third household.

This page explains how the rules work. It is not financial, tax or investment advice. Read the disclaimer.
