Step-by-Step Guide to Calculating FICA Taxes

Published June 7, 2026·6 min read

As a small business owner or solo entrepreneur, understanding your payroll tax obligations is crucial for maintaining compliance and managing your finances effectively. One of the key components of payroll taxes is the Federal FICA taxes, which include Social Security and Medicare taxes. In this guide, you'll learn how to calculate Federal FICA taxes for 2026, ensuring that you stay on top of your payroll responsibilities. This step-by-step approach will help you grasp the FICA tax calculation process and keep your business running smoothly.

The Federal Insurance Contributions Act (FICA) requires employers to withhold a portion of their employees' wages for Social Security and Medicare. For 2026, the Social Security tax rate is 6.2% on wages up to $176,100, while the Medicare tax rate is 1.45% on all wages. Knowing these rates and how to apply them will simplify your payroll tax calculations and help you avoid costly mistakes.

Understanding FICA Taxes

FICA taxes consist of two main components: Social Security and Medicare. Social Security provides benefits for retirees, disabled individuals, and survivors of deceased workers. Medicare, on the other hand, is a health insurance program for individuals aged 65 and older, as well as some younger people with disabilities.

The Social Security tax rate for 2026 is set at 6.2% on wages up to $176,100. This means that if an employee earns more than this threshold, the Social Security tax will only be applied to the first $176,100 of their wages. Medicare tax, which is 1.45%, applies to all wages without any upper limit. Additionally, high earners may be subject to an additional Medicare tax of 0.9% on wages exceeding $200,000 for single filers and $250,000 for married couples filing jointly.

How to Calculate FICA Taxes for 2026

Calculating FICA taxes involves a straightforward process. Here's how to do it step-by-step: 1. Identify the employee's gross wages — This is the total amount earned before any deductions. 2. Determine the applicable Social Security tax — Multiply the gross wages by 6.2%, but only if the wages are below $176,100. If wages exceed this limit, apply the tax only to $176,100. 3. Calculate the Medicare tax — Multiply the gross wages by 1.45%. This applies to all wages without an upper limit. 4. Sum the Social Security and Medicare taxes — Add the results from steps 2 and 3 to find the total FICA taxes owed. 5. Withhold the calculated amount from the employee's paycheck — Ensure you remit this amount to the IRS along with your payroll tax filings.

Additional State Payroll Taxes

Beyond federal FICA taxes, you may also need to consider state-level payroll taxes, particularly if you're in Washington state. Washington has several additional payroll taxes that you should be aware of: - Washington Paid Family and Medical Leave (PFML) tax is 0.74% of employee wages. - Washington Cares Fund tax is 0.58%, which supports long-term care benefits. - Washington Labor and Industries (L&I) insurance varies by industry and is an additional consideration when calculating payroll taxes.

Including these taxes in your payroll calculations is crucial to ensure compliance with state regulations and to avoid any penalties.
