| Field | Example value | Why it matters |
|---|---|---|

| YTD Social Security wages | $42,000.00 | Prevents tax above the annual Social Security limit. |
| YTD FUTA wages | $4,000.00 | Shows how much FUTA wage base remains. |

Formula used
1. FICA taxable wages
FICA Taxable Wages = Gross Wages − FICA-Exempt Wages
2. Social Security tax
Social Security Tax = min(Current FICA Taxable Wages, Social Security Wage Base − YTD Social Security Wages) × Social Security Rate
3. Medicare tax
Medicare Tax = Current FICA Taxable Wages × Medicare Rate
4. FUTA tax
FUTA Tax = min(Current FUTA Taxable Wages, FUTA Wage Base − YTD FUTA Wages) × (FUTA Rate − FUTA Credit Rate)
5. SUTA tax
SUTA Tax = min(Current SUTA Taxable Wages, SUTA Wage Base − YTD SUTA Wages) × SUTA Rate
6. Total employer tax liability
Total Liability = Social Security + Medicare + FUTA + SUTA + Local Payroll Tax + Workers’ Compensation Proxy

Frequently asked questions
1. What does this calculator estimate?
It estimates employer-side payroll taxes for one payroll period. It combines Social Security, Medicare, FUTA, SUTA, local payroll taxes, and an optional workers’ compensation proxy.
2. Why are year-to-date wages required?
Year-to-date taxable wages help the calculator stop applying taxes after a wage base is reached. This is especially important for Social Security, FUTA, and many state unemployment systems.
3. What are exempt wages?
Exempt wages are earnings or benefit amounts excluded from a specific payroll tax base. Common examples include certain pretax deductions or wage items treated differently under payroll rules.
4. Why is FUTA split into rate and credit?
Federal unemployment tax often starts with a gross rate and then applies a state credit. Separating them makes it easier to model the effective FUTA rate used in employer planning.
5. Is Additional Medicare Tax included?
No. Additional Medicare Tax is generally an employee withholding item, not an added employer match. This calculator focuses on the employer liability side of payroll costs.
6. Can I use this for multiple employees?
Yes, but calculate each employee separately when wage bases differ. You can then total the exported results or repeat the scenario for department-level payroll budgeting.
7. Why include a workers’ compensation proxy?
Some teams want a broader employer burden estimate, not only statutory payroll taxes. The proxy rate helps approximate insurance-related payroll cost during budgeting and workforce planning.
8. Is this calculator a tax filing substitute?
No. It is a planning and review tool. Always reconcile payroll registers, official forms, jurisdiction notices, and payroll provider outputs before filing returns or making deposits.
