This piece is the merged successor to two predecessor research pieces (no-tax-on-tips and no-tax-on-overtime-by-state), both of which previously cleared the fact-check publish gate at A grade. The merger is structural reorganization — every claim traces to a verified claim in one of the predecessor fact-checks. No new factual claims were introduced. The 70-claim § 224 (tips) fact-check coverage and the 58-claim § 225 (overtime) fact-check coverage are preserved end-to-end; the merger de-duplicates only the structurally identical shared mechanics (OBBB enactment, cap/phase-out/sunset, Schedule 1-A placement, FICA-still-applies disclaimer, § 6721 penalty framework, starting-point taxonomy, IRS Notice 2025-69 transition relief).
The source spread runs heaviest at law.cornell.edu for federal statute and CFR text (16 distinct citations), followed by irs.gov for Treasury/IRS guidance (15+ distinct pages), federalregister.gov for T.D. 10044, and state-legislature / state-DOR sites for the 50-state coverage. Tier-2 industry analysis (RSM US, Thomson Reuters Tax, EY, Tax Foundation, ITEP, Littler, Jackson Lewis, Pierce Atwood, Forvis Mazars, Baker Tilly, PayrollOrg) supplements the Tier-1 primary sources but is not load-bearing for any claim. Coverage: federal floor (statutes + 5 IRS guidance documents + 1 final rule + 1 proposed rule + 1 revenue ruling) + 50-state grid + DC + 3 named cases + 19 distinct federal statute / regulation / CFR citations + named state authorities for every non-default state posture.
