A FICA tip calculator is not the same thing as a normal tip calculator.
This page is about payroll tax on tip income, not about deciding whether to leave 15% or 20% at a restaurant. In U.S. tax terms, FICA means Social Security and Medicare tax. For 2026, the employee and employer Social Security rate is 6.2% each, the Medicare rate is 1.45% each, and the Social Security wage base is $184,500. Medicare has no wage cap.
That means a real FICA tip calculator has to answer two different questions.
First, how much Social Security and Medicare tax applies to tips for the employee. Second, if the business is eligible, how much employer FICA tip credit may be available under Section 45B. The IRS treats these as related but separate issues, which is why the calculator above shows both employee-side tax and employer-side credit.
This matters even more now because people often hear “no tax on tips” and assume tip income is now free of payroll tax.
That is not how the current rules work. The IRS says eligible workers may be able to claim a federal income-tax deduction for qualified tips for tax years 2025 through 2028, but tips still remain subject to Social Security and Medicare rules. The IRS also still says all cash tips received in any calendar month are subject to Social Security and Medicare tax.
How this FICA tip calculator works
This FICA tip calculator starts with the tip amount you want to test.
It then applies Social Security tax only to the part of those tips that still falls under the remaining Social Security wage base for 2026. That wage base is $184,500. Once wages and tips above that amount are reached for the year, Social Security tax stops, but Medicare tax continues on all covered wages and tips.
The calculator also adds regular Medicare tax at 1.45% on the full tip amount.
Then it checks whether the tip amount pushes the employee over the Additional Medicare threshold. The IRS says Additional Medicare tax is 0.9% and applies above $250,000 for married filing jointly, $125,000 for married filing separately, and $200,000 for all other filing statuses. Employers, however, must start withholding that extra 0.9% once wages they pay exceed $200,000 in the calendar year, regardless of the employee’s actual filing status.
That is why this calculator asks for filing status and year-to-date wages.
It is trying to estimate the tax that belongs on the tip amount itself, not just mirror a single pay stub withholding event. On a paycheck, the employer uses the $200,000 employer withholding rule. On the tax return, the employee’s actual filing-status threshold decides the final Additional Medicare result.
What counts as a tip for FICA purposes
For FICA, tip reporting starts with customer tips that are actually tips under IRS rules.
The IRS says cash tips include tips paid in cash, by check, by debit card, and by credit card. Employees who receive $20 or more in cash tips in a calendar month from one employer must report those tips to the employer by the 10th day of the following month. If total tips from that employer are under $20 for the month, they do not have to be reported to the employer, but they still remain taxable income on the employee’s return.
That reporting point matters because many people use a FICA tip calculator only after they realize payroll withholding did not happen.
The IRS says Form 4137 is used to calculate Social Security and Medicare tax on tips that were not reported to the employer, including allocated tips shown on Form W-2 that must still be reported as income. The IRS also says attaching Form 4137 ensures those tips are credited to the employee’s Social Security record.
So if you are a worker using this page, the tip field can help you estimate payroll tax on either reported tips or unreported tips.
But the employer-credit output is different. The employer FICA tip credit is based on tips on which the employer paid or incurred employer Social Security and Medicare tax. That means the employee-side estimate and the employer-side credit estimate can match only when the tip amount represents reported customer tips that the employer actually processed through payroll.
Service charges and auto-gratuities are not the same as tips
This is one of the most important distinctions on the page.
The IRS says distributed service charges and auto-gratuities are non-tip wages, not tips, and they are excluded from the employer FICA tip credit. Service charges are amounts determined by the employer rather than voluntarily left by the customer.
That is why the calculator has a separate field for distributed service charges or auto-gratuities.
Those amounts still matter for FICA. They are wages. They can push the employee closer to the Social Security wage base or the Additional Medicare threshold. They can also reduce the wage shortfall used in the employer credit formula. But they should not be treated as tips for Section 45B credit purposes.
In practical terms, if a restaurant adds a mandatory 18% charge for large parties and then pays that amount out to staff, that money is wage income, not tip income.
It may still be subject to Social Security and Medicare tax, but it does not belong in the “tip” bucket for the employer FICA tip credit. That is why a generic tax calculator can give the wrong answer if it lumps everything together.
How the employee FICA side is calculated
The employee side of this FICA tip calculator follows a simple structure.
Social Security tax on tips is 6.2%, but only up to the remaining Social Security wage base for the year. Medicare tax on tips is 1.45% on the full tip amount. Additional Medicare tax, if triggered, is another 0.9% on the portion over the applicable threshold. There is no employer match on Additional Medicare tax.
The formula looks like this:
Employee Social Security on tips = taxable tip portion under the 2026 Social Security wage base × 6.2%
Employee Medicare on tips = tip amount × 1.45%
Additional Medicare on tips = only the part above the applicable threshold × 0.9%
That means two employees can have the same tip amount and different FICA results.
If one employee is far below the Social Security wage base, almost all of the tip amount may be taxed for Social Security and Medicare. If another employee is already above the Social Security wage base for the year, only Medicare applies to the tip amount. If the employee is above the Additional Medicare threshold, the tip amount may also trigger the extra 0.9% employee tax.
How the employer FICA tip credit works
This is the second half of the keyword.
The IRS says the FICA tip credit equals the amount of employer Social Security and Medicare tax paid or incurred on certain employee tips. The credit is claimed on Form 8846 and is part of the general business credit. The IRS also says the credit is non-refundable.
For food and beverage businesses, the credit rules are not based on today’s $7.25 federal minimum wage.
The current Form 8846 instructions say food or beverage employers must still reduce creditable tips by the amount needed to reach the federal minimum wage rate in effect on January 1, 2007, which is $5.15 per hour. That old statutory floor still controls the Section 45B credit for food and beverage employers.
For tax years beginning after 2024, the credit was expanded to certain beauty service businesses.
The current Form 8846 instructions say the credit now also applies where tipping is customary for barbering and hair care, nail care, esthetics, and body and spa treatment services. For those businesses, the wage floor used in the credit calculation is the current federal minimum wage of $7.25 per hour, not $5.15.
That difference is why this calculator asks you to choose a business type.
If you pick food or beverage, the employer-credit side uses the $5.15 hourly basis. If you pick beauty services, it uses the $7.25 hourly basis. If you pick no employer credit, the calculator still shows employee FICA on tips but turns off the Section 45B estimate.
The employer credit formula in plain English
The employer credit formula starts with reported tips on which the employer paid FICA.
Then it subtracts the portion of tips that was needed just to bring wages up to the required statutory floor for that type of business. What is left is the creditable tip amount. The credit is generally 7.65% of that creditable tip amount, unless some of the employee’s wages and tips are already above the Social Security wage base, in which case that excess piece is only at the 1.45% Medicare rate.
The 2025 Form 8846 instructions also say Additional Medicare tax does not affect the employer credit because there is no employer share of Additional Medicare tax.
That is why the employee tax output can keep growing while the employer credit output does not. Additional Medicare belongs only to the employee side.
Real examples
Suppose a restaurant employee has $300 in reported tips for the month, $400 in direct wages, no distributed service charges, and 80 hours worked.
On the employee side, if the worker is still far below the Social Security wage base and far below the Additional Medicare threshold, the tips would generally produce $18.60 of employee Social Security tax and $4.35 of employee Medicare tax, for a total of $22.95 of employee FICA on the tips. The employer side would match the same $22.95 on those same tips. That follows the standard 6.2% plus 1.45% rates.
Now look at the employer credit side for the same restaurant example.
Using the food-and-beverage rule, the statutory floor is 80 hours × $5.15 = $412. If direct wages were only $400, there is a $12 shortfall. That means only $288 of the $300 in tips is creditable, and the potential employer FICA tip credit would be about $22.03 at 7.65%. That is the same logic the IRS uses in its own example, just with different numbers.
Here is a beauty example.
Assume a nail salon employee has $500 in reported tips, $600 in direct wages, no service charges, and 80 hours worked. Under the beauty-service rule, the wage floor is 80 × $7.25 = $580. Because direct wages already exceed that amount, the full $500 tip amount is creditable for the employer credit calculation. The potential employer credit would be $38.25, unless the Social Security wage base had already been exceeded.
Here is a high-income employee example.
Suppose an employee has already accumulated $184,400 in Social Security wages before the current pay period, and the current non-tip wages are $200. That leaves no Social Security wage base for the current tips, so the tip amount would generally be subject to Medicare but not Social Security. If the employee is also over the Additional Medicare threshold, the calculator would show Medicare plus the extra 0.9% employee tax on the applicable part of the tips.
What happens if the employer could not withhold enough tax from wages
This is another reason people search for a FICA tip calculator.
The IRS says if, by the 10th day of the next month, the employer does not have enough employee funds available to collect the employee share of Social Security and Medicare taxes on tips, the employer no longer has to collect it. The employer still reports the full tips on Form 941 or Form 944.
So if a paycheck looks light on tip withholding, that does not always mean the tax disappeared.
It may mean the employer did not have enough non-tip wages available to collect it. In that situation, the employee may still need to deal with the tax later, especially if some tips were unreported and Form 4137 becomes necessary.
Why this page does not calculate federal income tax on tips
Because that would be mixing different tax systems.
This page is for FICA. That means Social Security, Medicare, and the employer-side FICA tip credit. The new “no tax on tips” rule is an income-tax deduction for qualified tips, not a repeal of payroll tax on tips. The IRS says the deduction is for 2025 through 2028 and can apply to tips included on Form W-2, Form 1099, or reported on Form 4137, but the payroll-tax rules for tips still continue.
That makes this calculator cleaner and more useful.
If you want to know payroll tax on tips, this page answers that. If you want to estimate income tax too, that should be a separate calculator because withholding, deductions, filing status, and other income all affect the result.
Bottom line
A proper FICA tip calculator should do three things.
It should calculate employee Social Security and Medicare tax on tips using the current 2026 rates and wage base. It should account for Additional Medicare tax when the filing-status threshold is crossed. And it should estimate the employer FICA tip credit only when the business and the tip type actually qualify.
That is why this page separates tips from service charges, asks for year-to-date wage data, and includes a business-type field for Section 45B.
Use it to estimate employee payroll tax on tips, or to get a quick employer-side view of the FICA tip credit. Just remember that service charges are wages, not tips, and that unreported tips can still create Social Security and Medicare tax on Form 4137.
FAQ
What does a FICA tip calculator calculate?
It calculates payroll tax on tip income, mainly Social Security tax, Medicare tax, and sometimes Additional Medicare tax on the employee side. On this page, it also estimates the employer share of FICA on tips and the potential Section 45B employer FICA tip credit when the business qualifies.
What are the 2026 FICA rates on tips?
For 2026, Social Security is 6.2% for the employee and 6.2% for the employer, and Medicare is 1.45% for the employee and 1.45% for the employer. The Social Security wage base is $184,500 for 2026, and Medicare has no wage cap.
Are tips still subject to FICA after “no tax on tips”?
Yes. The IRS says eligible workers may be able to claim a federal income-tax deduction for qualified tips, but cash tips are still subject to Social Security and Medicare tax.
When do employees have to report tips to their employer?
Employees who receive $20 or more in cash tips from one employer in a calendar month must report those tips to the employer by the 10th day of the following month. Tips under that monthly amount do not have to be reported to the employer, but they still remain taxable income.
What form is used for unreported tips?
The IRS says Form 4137 is used to calculate Social Security and Medicare tax on tips not reported to the employer, including allocated tips that must be reported as income.
Are service charges the same as tips for the FICA tip credit?
No. The IRS says distributed service charges and auto-gratuities are non-tip wages and are excluded from the employer FICA tip credit.
Who can use the employer FICA tip credit?
Current Form 8846 instructions say the credit applies to businesses where tipping is customary for food or beverage service and, for tax years beginning after 2024, also for certain beauty service businesses such as hair care, nail care, esthetics, and body or spa treatments.
Why does the food-and-beverage employer credit use $5.15 instead of $7.25?
Because the current Form 8846 instructions say food and beverage employers cannot claim the credit on tips used to meet the federal minimum wage rate that was in effect on January 1, 2007, which was $5.15 an hour. Beauty-service employers use the current $7.25 federal minimum wage for this purpose.
Does Additional Medicare tax have an employer match?
No. The IRS says Additional Medicare tax is imposed only on the employee. There is no employer share, and it does not increase the employer FICA tip credit.
What if there were not enough wages to withhold FICA on tips?
The IRS says if the employer does not have enough employee funds available by the 10th day of the next month, the employer no longer has to collect the employee share of Social Security and Medicare tax on those tips, but the full tips are still reported on the payroll return.
