Introduction
Understanding Medicare tax basics is essential for employers managing payroll accurately and staying compliant. Medicare tax funds healthcare for older and certain disabled Americans—but employers play a vital role in withholding, matching, reporting, and remitting the correct amounts. This guide makes it simple and actionable.
What Is Medicare Tax?
Medicare tax is a mandatory payroll deduction used to fund Medicare, which provides healthcare for seniors and eligible younger individuals. Employers deduct part of this tax from employee wages and must match that amount. Self-employed individuals cover both portions themselves through the self-employment tax.
Understanding Medicare Tax Rates
Employers withhold 1.45% of each employee’s wages, and they must match that 1.45%. That makes a combined 2.9%. Additionally, employees earning above certain thresholds—like $200,000 for single filers—incur an extra 0.9% Medicare tax on earnings over that limit. Employers do not match this additional tax.
Calculating Medicare Tax
To calculate it accurately:
- Employees pay 1.45% on their total wages, plus 0.9% on wages exceeding threshold amounts.
- Employers pay 1.45% on all employee wages.
- For example, if someone earns $300,000 annually, they pay 1.45% on the first $200,000, plus 2.35% on the remaining $100,000. The employer contributes 1.45% on the full $300,000.
Timing and Remittance
Medicare taxes are withheld each pay period—weekly, bi-weekly, or monthly. Employers must deposit withholdings and their matching portions through the IRS’s EFTPS system based on their deposit schedule. Timely deposits protect your business from penalties.
Reporting Requirements
Employers report Medicare tax details on Form 941 each quarter, showing total wages withheld and employer matching. At year's end, the total Medicare amount appears in box 5 on each employee’s W-2. Businesses using alternate forms like 943 or 944 follow similar reporting logic but on different schedules.
Handling Tips and Non-Cash Compensation
Tips exceeding $20/month must be reported to employers so Medicare tax can be correctly calculated on total earned income. Likewise, stock options, bonuses, and other non-cash pay must include fair market value for Medicare tax purposes.
Compliance and Recordkeeping
Accurate payroll records are vital—include wages paid, Medicare tax withheld, and amounts due from both employee and employer. Timely filing of Form 941 and all regulated documents prevents fines and audits. Remember to include additional Medicare tax from higher earners in your books.
Common Employer Mistakes to Avoid
- Underwithholding the additional 0.9% on high-income employees.
- Failing to remit the 1.45% employer match.
- Omitting tips or bonuses from Medicare tax calculations.
- Incorrect or late reporting on Form 941 or W-2.
