Understanding Payroll Tax Rates for 2026

To ensure your payroll tax calculator accuracy, it's essential to be aware of the 2026 IRS rates. For Social Security, the rate remains at 6.2% on wages up to $176,100, as set by the IRS (see IRS Rev. Proc. 2025-43). The Medicare tax is 1.45%, which applies to all wages. For Washington state, the Paid Family and Medical Leave (PFML) tax is now 1.13%, with the employee share at 0.8072%, according to the Washington Employment Security Department's November 2025 rate notice. Additionally, the WA Cares Fund tax rate is 0.58%. Workers' Compensation rates under WA L&I vary depending on the risk class of your business. Being well-informed about these rates will help you input the correct information into your payroll tax calculator.
