The numbers at a glance

The 2026 figures are final: they belong on the return filed in early 2027. The 2027 figures are shown where the IRS has published them (Rev. Proc. 2026-35, November 5, 2026) and marked “to come” where it has not; the retirement-plan limits usually follow in November. State figures are updated as each state’s revenue department publishes them.

Already scheduled

These changes are already law, written to start or stop on a set date. Nobody has to vote on them.

2026–2027. Catch-up contributions go Roth for higher earners. If you are 50 or older and earned more than $150,000 in Social Security wages the year before, your 401(k) catch-up must go into the Roth side: no deduction now, tax-free later.
2027. The Saver’s Match replaces the Saver’s Credit: up to $1,000 deposited directly into your retirement account, phasing out by $35,500 of income single and $71,000 joint.
2027. A new federal scholarship tax credit, up to $1,700 for gifts to approved scholarship organizations. Whether your state opts in is up to each state. The $2,000 threshold for Forms 1099-NEC and 1099-MISC starts rising with inflation.
End of 2028. The deductions for tips, overtime, car loan interest and the $6,000 senior deduction expire unless Congress extends them. Last birth year for the $1,000 Trump account deposit.
2027–2029. The SALT cap rises 1% a year, to about $41,600 in 2029. In 2030 it drops back to $10,000.
Permanent, with no expiration date: the rates and brackets, the larger standard deduction, the $2,200 child tax credit, the $15 million estate exemption, the 20% deduction for business owners, and the charitable deduction for non-itemizers. “Permanent” means until Congress changes it.

Behind the scenes

A preparer works from two years of tables at once. The 2026 tables settle the return on the desk. The 2027 tables settle everything else raised in the same appointment: pension withholding, estimated payments, how far a Roth conversion can go before the next Medicare tier. When a 2027 figure hasn’t been published, the plan is built on the 2026 figure and flagged for a re-check in the spring.
