Payroll taxes don’t look the same in every state. Federal rules set a common starting point, but state and local rules can change what employees take home, what employers pay on top of wages, and how much paperwork a business must handle.
For a small business, the practical question is not just “What is the tax rate?” It is “What will this employee cost us in this location, and what will their paycheck look like?” The answer depends on the worker’s work location, pay, benefits, state unemployment tax rate, and sometimes city or county rules.
This guide explains the main differences, shows how to estimate the true cost of hiring, and points to free calculators and state resources. It also covers QuickBooks and Gusto as payroll tools—not as substitutes for checking official tax rules.
Start with the taxes that apply nationwide
Most employers begin with federal payroll obligations. These generally apply regardless of the state where an employee works:
- Social Security: Employer and employee contributions are generally 6.2% each, up to the annual wage limit. Medicare: Employer and employee contributions are generally 1.45% each, with no wage limit. Higher-paid employees may also owe Additional Medicare Tax; that extra tax is generally withheld from the employee, not matched by the employer. Federal unemployment tax (FUTA): The standard FUTA rate is 6.0% on the first $7,000 of an employee’s wages. Many employers receive credits for state unemployment taxes, which can reduce the effective FUTA rate. Credit reductions can affect employers in certain states. Federal income tax withholding: Employers withhold it from employee wages using the employee’s Form W-4 and IRS rules. It is not an employer tax in the same way as the employer share of Social Security.
Rates, wage limits, and special rules can change. Check current IRS guidance before setting up payroll or making a forecast.
What changes by state?
When people search for payroll taxes by state, they often mean several different things. Some are taxes paid by the employer; others are withheld from an employee’s paycheck. A state may also have required insurance programs or paid-leave contributions that affect payroll without being labeled a traditional income tax.
State or local item Who generally pays? Why it varies State income tax withholding Employee, withheld by employer States set their own rates, brackets, exemptions, and withholding methods. Some states have no broad-based individual income tax. State unemployment insurance (SUI or SUTA) Usually employer; a few states also withhold an employee contribution Rates depend on the state, employer’s experience rating, industry or account status, and taxable wage base. State disability or paid-family-leave contributions Depends on the state and program Some programs are funded through employee deductions, employer contributions, or both. Rules and wage limits differ. Local income or payroll taxes Often employee withholding, but rules vary Cities, counties, school districts, or other local jurisdictions may impose taxes or require special withholding. Workers’ compensation insurance Generally employer-funded insurance, not a payroll tax Coverage rules, rates, classifications, and exemptions are state-specific.Two employees with the same salary can therefore have different take-home pay because of state income tax, local tax, or employee-funded programs. Two employers paying the same salary can also have different costs because their unemployment rates, wage bases, workers’ compensation classifications, and paid-leave obligations differ.
State unemployment tax is a major employer cost
State unemployment tax is one of the most important state-level employer taxes to budget for. Each state sets a taxable wage base—the amount of each employee’s wages subject to the tax—and assigns employers a rate. New employers commonly start with a state-assigned rate. Over time, an employer’s experience with unemployment claims can affect its rate, subject to state rules.
A simple estimate is:
State unemployment tax estimate = taxable wages × employer’s SUI rate
For example, suppose a state’s wage base is $10,000 and a business’s rate is 3%. The employer would owe about $300 for an employee who earns at least $10,000, before considering any state-specific adjustments. If the rate were 1%, the estimate would be $100. Once the employee’s wages exceed the wage base, additional wages may not be subject to that state tax for the year.
This is only a back-of-the-napkin example: actual rates, wage bases, new-employer rules, and account adjustments vary. Don’t use a neighboring business’s rate as your own. Check your assigned rate notice and state unemployment agency account.
How state rules affect paycheck and take-home pay
An employee’s net pay is what remains after gross wages are reduced by taxes and other deductions. State and local withholding can make a noticeable difference, but a paycheck estimate also depends on federal withholding, pay frequency, W-4 details, pre-tax benefits, retirement contributions, and other deductions.
For a rough paycheck estimate, identify:
Gross pay: Salary or hourly wages for the pay period, including applicable overtime, commissions, or bonuses. Federal withholding and FICA: Estimate federal income tax withholding, Social Security, and Medicare using current IRS rules. State and local withholding: Use the employee’s work location and current state and local forms or withholding tables. Employee-funded programs: Include applicable disability, paid-leave, or unemployment deductions. Benefits and other deductions: Account for health insurance, retirement contributions, garnishments, and any other authorized deductions.For example, imagine an employee earns $1,500 gross in a biweekly paycheck. The employee’s federal and FICA withholding might be similar in two states, but state income tax and a state paid-leave deduction could differ. The employee could receive a different net paycheck even though gross pay is identical. That difference does not automatically mean the employer’s cost changed by the same amount: employee withholding is generally taken from gross wages, while employer taxes and contributions are additional costs.
Paycheck estimates are useful for planning and discussing compensation, but they are not a guarantee of exact net pay. A calculator may not know an employee’s complete tax situation, benefit elections, or local requirements. Confirm payroll setup before issuing the first check.
Calculate the true cost of hiring an employee
Salary is only one part of the hiring budget. A practical first-year estimate should separate employee deductions from employer-paid costs.
Estimated employer cost = gross wages + employer payroll taxes + required insurance and contributions + benefits + recruiting and setup costs
For a $60,000 annual salary, a rough federal employer-side starting point is 7.65% for Social Security and Medicare, or $4,590, assuming all wages are subject to both taxes and ignoring special situations. FUTA and state unemployment taxes may add more, though FUTA is generally limited to a small wage base and may be reduced by credits. State and local requirements, workers’ compensation, health benefits, retirement contributions, and paid leave can add substantially to the total.
This estimate is deliberately not a universal “loaded labor cost” percentage. Workers’ compensation rates can differ by job classification, and health coverage can cost far more than payroll taxes. Use your actual state unemployment rate, insurance quote, and benefit costs rather than relying on a generic multiplier.
Include costs that do not appear as a tax line
- Recruiting, background checks, and onboarding time Payroll software, accounting support, and required notices Health, dental, or vision benefits and employer retirement contributions Workers’ compensation and any state-required coverage Paid leave, scheduling coverage, and training time Equipment, licenses, uniforms, or role-specific tools
Employee turnover cost math
Turnover affects the value of a hiring decision, but it is easy to overstate the cost by applying a broad rule of thumb. Build a simple estimate from costs your business can identify.
Estimated cost per departure = recruiting costs + onboarding and training costs + temporary coverage costs + vacancy-related lost output
Suppose a business spends $1,200 on recruiting and checks, uses 30 manager and trainer hours at an estimated loaded rate of $35 per hour ($1,050), and spends $800 on temporary coverage. If it estimates $2,000 in lost output during the vacancy and ramp-up period, the rough total is $5,050. This is an estimate—not a guaranteed savings figure—and the lost-output amount is the least certain part.
Now connect that estimate to payroll planning. If turnover costs the business $5,050 per departure and it has four departures in a year, the modeled annual cost is $20,200. Compare that with the cost of retention measures, such as more training time, a wage adjustment, or improved scheduling. Avoid counting the same cost twice—for example, don’t include overtime coverage both as temporary coverage and as lost output.
Free small business calculators and payroll tools
Free calculators can help with early budgeting, but check what each one includes. Some estimate employee take-home pay; others estimate employer taxes, workers’ compensation, or total compensation. A calculator that asks only for salary and state cannot reliably account for every local tax, benefit deduction, or employer-specific unemployment rate.
- IRS Tax Withholding Estimator: Useful for individuals checking federal withholding. It is not a complete employer-cost calculator. State revenue department withholding calculators and tables: Use these for current state withholding guidance. Some states publish worksheets rather than a calculator. State unemployment agency resources: Check the state’s taxable wage base, new-employer rate, payment schedule, and your assigned rate. QuickBooks payroll resources: QuickBooks offers payroll products and related tools that may help estimate payroll costs or manage payroll, depending on the product and plan. Verify which features, tax filings, and state services are included; pricing and coverage can vary. Gusto payroll resources: Gusto offers payroll products and calculators or guides for pay and hiring estimates. Confirm state availability, plan limits, filing coverage, and any add-on fees before relying on a feature.
When comparing QuickBooks and Gusto, look beyond the advertised base price. Check per-employee charges, contractor pricing, state filing support, year-end forms, benefits administration fees, and whether multi-state payroll or workers’ compensation support costs extra. Payroll tax filing errors can create penalties, so confirm exactly who is responsible for registration, filings, deposits, and corrections.
State resources to check before your first payroll
Use official state resources for the rules that apply to your business. Start with the state department of revenue for income tax withholding, the state labor or unemployment agency for SUI, americanbusinesscenter.org and the state insurance or workers’ compensation agency for coverage requirements. Also check the relevant city or county website if the employee works in a locality with its own tax.
For a remote or hybrid team, the employee’s work location can matter—not just the company’s headquarters. An employee working from another state may trigger registration, withholding, unemployment, workers’ compensation, or business-licensing obligations. Ask a payroll professional or tax adviser when the facts are unclear, especially before hiring across state lines.
A practical checklist for comparing payroll taxes by state
Confirm where the employee will physically work and whether local taxes apply. Find current state income tax withholding forms, tables, and filing deadlines. Get your employer-specific unemployment rate and confirm the state wage base. Check whether disability, paid-family-leave, or other contributions apply, and who pays them. Obtain workers’ compensation requirements and a quote for the employee’s job classification. Estimate employee net pay separately from employer-paid costs. Compare payroll providers by total fees, filing responsibilities, and state support—not just the monthly headline price. Recheck rules and rates each year, and whenever you hire in a new state.The bottom line
Payroll taxes by state change because states and local governments set their own withholding rules, unemployment programs, and other payroll-related contributions. Those differences affect employee take-home pay and employer costs in different ways. Start with federal obligations, add the rules for the employee’s work location, and keep employer taxes separate from employee deductions in your budget.
Free calculators from government agencies and payroll providers can make estimates easier, while tools such as QuickBooks and Gusto may help with payroll administration. But calculators are only as good as their assumptions. Use official state resources, check your actual employer rates, and review the full fee schedule before choosing a payroll service.
