The Self-Employment Tax Deduction is a FEDERAL deduction — federal eligibility rules apply uniformly nationwide.

Some states "decouple" from federal — verify Arizona's 2026 state tax form for confirmation.

Federal phase-outs depend on your modified adjusted gross income (MAGI) — high-income filers may see reduced or fully phased-out benefits. Check IRS Publication for the 2026 phase-out thresholds.
