What This Calculator Does

This payroll reconciliation calculator helps accountants, bookkeepers, payroll specialists, and business owners verify gross-to-net payroll calculations. It computes Social Security and Medicare (FICA) withholding using 2026 rates and wage bases, applies federal and state income tax withholding, and accounts for pre-tax and post-tax deductions including 401(k), health insurance, HSA, and FSA contributions. The tool also calculates employer-side payroll costs and tracks the Social Security wage base ($184,500 for 2026) to determine when withholding stops.

Real-World Use Cases

Common Mistakes to Avoid

• Forgetting that Social Security tax stops at the wage base. For 2026, withholding stops once cumulative wages reach $184,500. Paychecks after that threshold have higher net pay.

• Not distinguishing between pre-tax and post-tax deductions. Pre-tax deductions (traditional 401(k), health insurance) reduce federal and state taxable income. Post-tax deductions (Roth 401(k), garnishments) do not reduce tax withholding.

• Applying the additional Medicare tax to all employees. The 0.9% additional Medicare tax only applies to wages over $200,000. It is an employee-only tax; the employer does not match it.

• Using the wrong pay frequency multiplier. Weekly: 52 periods. Biweekly: 26. Semi-monthly: 24. Monthly: 12. Using the wrong multiplier causes incorrect annualized income calculations.

• Forgetting employer-side FICA costs. The employer pays matching Social Security (6.2%) and Medicare (1.45%) on top of gross pay. This increases the true cost of employment by approximately 7.65%.
