Gives an AI assistant the official 2025, 2026 and 2027 retirement numbers that are newer than its training data: 401(k), IRA, SIMPLE and HSA limits, the SECURE 2.0 age 60-63 catch-up and Roth catch-up rule, and the Social Security COLA, wage base and earnings test. Every figure is copied from irs.gov or SSA's Federal Register notice. Limits the IRS has not announced yet are reported as not published, never guessed.
