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 and marked “to come” where it has not. Colorado’s 2027 figures depend on a legislative session that runs January to May. Booklet pages 3–4.

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. Colorado has opted in. 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.
