Our 2019 payroll tax calculator uses the following methodology:
1. Social Security Tax (FICA)
6.2% of gross pay up to the 2019 wage base limit of $132,900. The formula is:

2. Medicare Tax
1.45% of gross pay with no wage base limit. Plus an additional 0.9% for earnings over $200,000:
Medicare Tax = Gross Pay × 0.0145 + MAX(0, (Gross Pay - $200,000) × 0.009)
3. Federal Income Tax
Calculated using 2019 IRS tax tables based on:
- Filing status

Interactive FAQ
What were the 2019 Social Security and Medicare tax rates?
For 2019, the Social Security tax rate was 6.2% on wages up to $132,900 (the wage base limit). The Medicare tax rate was 1.45% on all wages, with an additional 0.9% tax on wages exceeding $200,000. Employers match these rates for their portion of payroll taxes.
How do I know if I’m withholding enough federal income tax?
You can check your withholding amount using the IRS Tax Withholding Estimator. Ideally, your withholding should closely match your actual tax liability. If you consistently receive large refunds, you may be withholding too much. If you owe significant amounts at tax time, you may need to increase your withholding or make estimated tax payments.
What’s the difference between gross pay and net pay?
Gross pay is your total compensation before any deductions. Net pay (or take-home pay) is what remains after all taxes and other deductions (like retirement contributions or health insurance premiums) are subtracted from your gross pay. The difference between these two amounts represents your total payroll deductions.
How often should I update my W-4 form?
You should update your W-4 form whenever you experience major life changes such as marriage, divorce, having a child, or if your financial situation changes significantly. The IRS recommends checking your withholding at the beginning of each year or when the tax law changes. You can submit a new W-4 to your employer at any time.
Are payroll taxes the same as income taxes?
No, payroll taxes and income taxes are different. Payroll taxes specifically fund Social Security and Medicare programs (collectively known as FICA taxes). Income taxes fund general government operations. Both are typically withheld from your paycheck, but they serve different purposes and have different rates.
What happens if my employer doesn’t withhold payroll taxes?
If your employer fails to withhold payroll taxes, they are violating federal law. You should still report all your income when filing taxes. The IRS may hold both you and your employer responsible for unpaid taxes. If you suspect your employer isn’t withholding properly, you can report them to the IRS using Form 3949-A.
Can I opt out of payroll taxes?
No, you cannot legally opt out of payroll taxes if you’re an employee. These taxes are mandatory for most workers. However, some religious groups may qualify for exemptions from Social Security and Medicare taxes. Self-employed individuals pay both the employer and employee portions of payroll taxes through the self-employment tax.
