How to calculate Social Security and Medicare tax for 2016
Calculating Social Security and Medicare tax for 2016 is straightforward once you know the wage base, the tax rates, and whether you are computing the employee side, the employer side, or the self-employed equivalent. In 2016, the employee Social Security tax rate was 6.2% and applied only up to the annual wage base of $118,500. The Medicare tax rate was 1.45% on all covered wages, with no wage cap. Some higher earners also owed an Additional Medicare Tax of 0.9% above the applicable filing-status threshold.
If you are an employee, your employer generally withholds 6.2% for Social Security and 1.45% for Medicare from your paycheck. Your employer also pays a matching 6.2% Social Security tax and 1.45% Medicare tax. If you are self-employed, you effectively pay both halves through self-employment tax rules, which means a combined 12.4% Social Security tax on covered earnings up to the annual limit and 2.9% Medicare tax on covered earnings, plus any applicable Additional Medicare Tax.
2016 payroll tax rates and limits at a glance
For most people, the first thing to understand is that Social Security and Medicare do not work the same way. Social Security has a wage base, which means once your covered wages reach the annual limit, no more Social Security tax is due for the remainder of the year. Medicare has no such wage base, so the 1.45% standard employee rate continues to apply to all covered wages. For higher earners, the Additional Medicare Tax also applies above a threshold tied to filing status.
| 2016 Payroll Tax Item | Employee Rate | Employer Rate | Self-Employed Equivalent | Limit or Threshold |
|---|---|---|---|---|
| Social Security | 6.2% | 6.2% | 12.4% | $118,500 wage base |
| Medicare | 1.45% | 1.45% | 2.9% | No wage cap |
| Additional Medicare Tax | 0.9% | 0% | 0.9% | Applies above filing-status threshold |
Additional Medicare Tax thresholds for 2016
The Additional Medicare Tax is easy to miss because it only affects earnings above a threshold. For payroll withholding, many employers start withholding it after an employee earns more than $200,000 during the calendar year, regardless of filing status. However, your actual tax liability on your return is based on your filing status. That is why a calculator like this asks for your filing status.
| Filing Status | 2016 Additional Medicare Tax Threshold | Additional Tax Rate Above Threshold |
|---|---|---|
| Single | $200,000 | 0.9% |
| Head of household | $200,000 | 0.9% |
| Qualifying widow(er) | $200,000 | 0.9% |
| Married filing jointly | $250,000 | 0.9% |
| Married filing separately | $125,000 | 0.9% |
Step by step example for an employee in 2016
Suppose you earned $85,000 in wages in 2016 and filed as single. Because your wages are below the Social Security wage base of $118,500, all $85,000 is subject to Social Security tax. Your employee Social Security tax is $85,000 multiplied by 6.2%, which equals $5,270. Your employee Medicare tax is $85,000 multiplied by 1.45%, which equals $1,232.50. Since your wages do not exceed the $200,000 Additional Medicare Tax threshold for a single filer, your additional amount is zero. Your total employee-side Social Security and Medicare tax is therefore $6,502.50.
Your employer would also generally owe a matching $5,270 in Social Security tax and $1,232.50 in Medicare tax. That employer match is not deducted from your net pay, but it is part of the total payroll tax cost tied to your wages. If you are comparing the employee burden to the full labor cost of compensation, both sides matter.
Example above the Social Security wage base
Now assume a single employee earned $150,000 in 2016. Social Security tax applies only up to $118,500. The employee Social Security tax would be $118,500 multiplied by 6.2%, or $7,347. Medicare tax would be $150,000 multiplied by 1.45%, or $2,175. Because $150,000 is still below the single-filer Additional Medicare Tax threshold of $200,000, no extra 0.9% applies. In this example, the cap matters because not all wages are subject to Social Security tax, but all wages remain subject to standard Medicare tax.
How the 2016 calculation works for self-employed individuals
Self-employed workers need to think about payroll taxes a little differently. Instead of an employee share and an employer share, the self-employed person effectively pays both sides. That means 12.4% for Social Security up to the 2016 wage base and 2.9% for Medicare on covered earnings. If net earnings exceed the Additional Medicare Tax threshold for the filing status, the excess is taxed at another 0.9%.
As a practical matter, some tax return calculations for self-employment tax involve adjustments to net earnings from self-employment before applying the rate. A simple calculator like this is best used as a planning estimate rather than as a substitute for a completed tax return. It is still very helpful for budgeting, estimated tax planning, and understanding how sharply payroll taxes change around the Social Security wage base.
Self-employed example
Assume a self-employed individual earned $140,000 in 2016 and filed as married filing jointly. The Social Security portion would apply to the first $118,500 at 12.4%, which produces $14,694. The Medicare portion would apply to the full $140,000 at 2.9%, resulting in $4,060. Since the married-joint Additional Medicare Tax threshold is $250,000, no extra 0.9% would apply in this example. The estimated total payroll-tax-style burden would be $18,754.
Why the 2016 Social Security wage base matters so much
The Social Security wage base is one of the most important inputs in any payroll tax estimate. In 2016, it was $118,500. This means an employee earning $118,500 and an employee earning $300,000 both paid the same amount of employee Social Security tax for the year: $7,347. The higher earner still paid more Medicare tax, but not more standard Social Security tax beyond the cap.
That wage base can affect compensation planning, year-end withholding, and even the timing of bonuses. If a worker changes jobs during the year, each employer may withhold Social Security tax without full awareness of wages paid by prior employers. That can sometimes result in excess Social Security withholding, which may be claimed back on an individual income tax return if the total withheld exceeds the annual maximum. Medicare withholding does not cap out the same way, so this issue is much more common with Social Security than with Medicare.
Common mistakes when people calculate 2016 payroll taxes
- Using the wrong Social Security wage base. For 2016, the correct wage base is $118,500.
- Applying Social Security tax to all wages above the cap. That overstates tax for higher earners.
- Forgetting that Medicare has no wage cap.
- Ignoring Additional Medicare Tax for higher-income taxpayers.
- Assuming the employer pays the Additional Medicare Tax. Employers do not match that 0.9% tax.
- Confusing payroll withholding rules with actual year-end filing-status liability.
Simple checklist for accurate 2016 estimates
- Start with annual covered wages or net earnings.
- Determine whether you are calculating employee tax or self-employed tax.
- Apply the Social Security tax only up to $118,500.
- Apply regular Medicare tax to all covered wages.
- Check whether wages exceed the Additional Medicare Tax threshold for your filing status.
- If needed, add 0.9% of the amount above the threshold.
- Separate employee, employer, and total amounts so you know what affects your paycheck versus overall payroll cost.
2015 versus 2016 comparison
Historical context can help you understand whether a 2016 estimate seems reasonable. The Social Security wage base increased from $118,500 in 2015 to the same $118,500 in 2016, meaning there was no change in the cap that year. Standard Social Security and Medicare rates also remained the same. The main planning issue for many taxpayers was not a rate change, but properly applying the cap and recognizing whether Additional Medicare Tax would apply.
| Year | Social Security Wage Base | Employee Social Security Rate | Employee Medicare Rate | Additional Medicare Tax |
|---|---|---|---|---|
| 2015 | $118,500 | 6.2% | 1.45% | 0.9% above threshold |
| 2016 | $118,500 | 6.2% | 1.45% | 0.9% above threshold |

Final takeaway
To calculate Social Security and Medicare tax for 2016, focus on three numbers: the 6.2% Social Security rate per side, the $118,500 Social Security wage base, and the 1.45% Medicare rate per side with no cap. Then determine whether the Additional Medicare Tax of 0.9% applies based on filing status and income level. Once you break the tax into these components, the calculation becomes much easier to understand and verify.
The calculator above is designed to make that process faster. It can help you estimate employee withholding, employer matching tax, or the self-employed equivalent burden, and it visualizes the result with a chart so you can see exactly how each tax component contributes to your total. For final return preparation or special cases, always compare your estimate with current IRS instructions or professional tax advice.
