About Know Paycheck
Know Paycheck is a free Ohio paycheck calculator. We show federal, Ohio state, FICA, city / RITA and school-district withholding in one instant estimate.
Why Ohio-first?
Most national calculators skip the taxes Ohio workers actually pay: municipal tax (often 2–2.5% where you work) and school-district tax (0.25–2% where you live). We also track Ohio's HB96 transition to a flat 2.75% tax over $26,050 in 2026, the $184,500 Social Security wage base, and correct 401(k)-vs-FICA handling.
