payroll tax for employer calculator

How this payroll tax for employer calculator works

This calculator is built to give business owners, finance teams, and HR managers a fast way to estimate annual employer-side payroll taxes. It focuses on the taxes paid by the company, not the amounts withheld from employees.

Because each payroll tax has different wage bases and rules, the most accurate method is to enter taxable payroll for each tax type separately. That is why this calculator asks for:

• Total gross payroll (for effective rate tracking)
• Social Security taxable payroll
• Medicare taxable payroll
• FUTA taxable payroll and FUTA rate
• SUTA taxable payroll and SUTA rate
• Optional local payroll tax rate

What taxes are included

1) Employer Social Security tax

Employers generally owe 6.2% on Social Security taxable wages. Wages above the annual wage base are not subject to Social Security tax, which is why this taxable payroll amount is often lower than gross payroll.

2) Employer Medicare tax

Employers generally owe 1.45% on all Medicare taxable wages. There is no wage cap for employer Medicare tax.

3) FUTA (Federal Unemployment Tax Act)

FUTA is usually calculated on a limited wage base per employee. Many employers who receive the full state unemployment credit effectively pay 0.6% on FUTA taxable wages.

4) SUTA (state unemployment tax)

SUTA varies by state and by employer experience rating. Rates can vary significantly, so using your current agency-assigned rate gives the best estimate.

5) Local payroll taxes (if applicable)

Some jurisdictions impose local employer payroll taxes. Enter your local rate if this applies to your location.

Formula summary

The calculator uses these formulas:

• Social Security tax = Social Security taxable payroll × 6.2%
• Medicare tax = Medicare taxable payroll × 1.45%
• FUTA tax = FUTA taxable payroll × FUTA rate
• SUTA tax = SUTA taxable payroll × SUTA rate
• Local payroll tax = Gross payroll × Local rate
• Total employer payroll taxes = Sum of all items above

Example calculation

Suppose your company has these annual inputs:

• Gross payroll: $500,000
• Social Security taxable payroll: $420,000
• Medicare taxable payroll: $500,000
• FUTA taxable payroll: $70,000 at 0.6%
• SUTA taxable payroll: $120,000 at 2.7%
• Local payroll tax: 0%

Your estimated employer payroll taxes would be the combined amount from these categories. The calculator also gives an estimated monthly cost and an effective tax rate versus gross payroll.

Tips to improve payroll tax accuracy

Use taxable payroll, not just gross payroll

Gross payroll alone can overstate or understate employer tax liability because different taxes have different wage caps and eligibility rules.

Update SUTA rate annually

Your state unemployment rate can change each year based on claims history and agency rules. A stale SUTA rate can materially distort planning numbers.

Review FUTA credit status

If your state has a FUTA credit reduction, your effective FUTA rate may be higher than 0.6%.

Reconcile estimates against actual payroll reports

Use this calculator for planning and budget scenarios, then compare to payroll provider filings and quarterly returns.
