How Do Payroll Taxes Change by State?

Payroll taxes don’t look the same in every state. Federal rules set a common baseline, but state and local rules can change what an employee takes home and what an employer pays on top of wages. The difference can affect your hiring budget, paycheck estimates, payroll setup, and filing deadlines.

The practical takeaway: don’t use one national percentage to estimate payroll costs. Start with the employee’s work location, check the relevant state resources, and calculate both sides of the payroll equation: deductions from the employee’s pay and taxes or contributions paid by the employer.

What “payroll taxes by state” actually means

Payroll includes several kinds of taxes and required contributions. Some are withheld from an employee’s gross pay; others are paid by the employer. A state may also require an employer to collect or contribute to programs that aren’t formally called taxes.

Payroll item Usually paid by What can vary by state? Federal income tax withholding Employee, withheld by employer Federal rules apply nationwide; the amount withheld depends on the employee’s Form W-4 and pay. Social Security and Medicare (FICA) Employee and employer Generally consistent federally, though special rules can apply to some wages and employees. State income tax withholding Employee, withheld by employer States differ in whether they have an income tax, their rates and brackets, and withholding rules. State unemployment insurance (SUI or SUTA) Employer; some states also withhold an employee contribution Rates, wage limits, experience-rating systems, and payment rules vary. Disability, paid leave, or similar programs May be employee-paid, employer-paid, or shared Program availability, contribution rates, wage limits, and employer-size thresholds vary. Local income or payroll taxes Depends on the jurisdiction Some cities, counties, or other local areas impose additional withholding or employer obligations.

Which payroll taxes vary most from state to state?

State income tax withholding

Some states tax wage income; others don’t impose a broad state individual income tax. Even among states that do, withholding can depend on tax brackets, allowances or other state forms, filing status, and the employee’s wages. A state without an individual income tax may still have other payroll-related requirements, such as unemployment contributions or paid-leave programs.

Withholding is a prepayment toward an employee’s tax bill—not necessarily the exact tax they will owe. An employee’s final state tax liability depends on their full-year income, deductions, credits, and personal situation. Payroll estimates should therefore be described as estimates, not promises of an exact refund or bill.

State unemployment insurance

Employers generally pay state unemployment insurance contributions. The state sets the rules, including taxable wage limits and rate schedules. An employer’s assigned rate may depend on factors such as its industry, claims history, and how long it has been operating. That means two businesses in the same state may pay different rates.

Some states also require employees to contribute to unemployment programs. Don’t assume the employer is the only party responsible: check the state’s current guidance and payroll setup instructions.

Paid family leave, disability, and other programs

States may require payroll contributions for paid family or medical leave, temporary disability insurance, or related benefits. Responsibility can fall on the employee, employer, or both, and rules may differ by employer size. A program can also have a wage cap, exemption, or special treatment for certain types of workers.

These items are easy to miss when someone estimates employer taxes using only federal payroll taxes and unemployment insurance. They can also affect take-home pay when contributions are withheld from the employee.

Local taxes and work location

In some places, the employee’s city, county, or other local jurisdiction matters. Remote work can make this more complicated: an employee may live in one state and perform work in another, or work from different locations during the year. Tax withholding and unemployment coverage do not always follow the same location rule.

For a new hire, confirm where the employee will physically perform work, where they live, and whether they will travel or work remotely. If the facts are complicated, ask a qualified payroll or tax professional how the state and local rules apply.

Employee paycheck versus employer cost

A paycheck estimate and a hiring-cost estimate answer different questions. Take-home pay starts with an employee’s gross wages, then subtracts employee-side deductions. Employer cost starts with gross wages and adds employer-side taxes and required contributions.

Employee paycheck: gross pay minus federal and applicable state or local withholding, employee payroll-tax shares, benefit deductions, and other authorized deductions.
Employer cost: gross wages plus employer payroll taxes, unemployment contributions, required program contributions, benefits, workers’ compensation, and other employment costs.

For example, an employee can have state income tax withheld from a paycheck without that withholding being an extra employer tax. The employer generally sends the withheld amount to the relevant authority, but it came out of the employee’s gross pay. By contrast, an employer unemployment contribution is an additional cost of employing the worker.

A back-of-the-napkin example of the true cost of hiring

Suppose a small business hires an employee at an annual salary of $60,000. For a rough planning example, assume employer-side payroll taxes and state or local contributions total 8% of wages. That would add $4,800, producing an estimated payroll cost of $64,800 before benefits, workers’ compensation, recruiting, equipment, and paid time off.

This is a budgeting illustration, not a standard rate. The actual percentage could be higher or lower based on the state, local rules, unemployment rate assignment, wage limits, industry, employee benefits, and other circumstances. Some payroll items apply only to wages up to a limit, so multiplying one percentage by every dollar of salary may not match the final calculation.

A more complete planning worksheet might look like this:

Cost item Illustrative annual amount Notes Gross wages $60,000 Employee’s salary before deductions. Employer taxes and state contributions $4,800 Illustrative 8%; verify current state and employer-specific rates. Benefits and insurance Varies Health coverage, retirement contributions, workers’ compensation, and other benefits. Recruiting, onboarding, and equipment Varies May include job advertising, background checks, training, and devices.

The example passes a useful sanity check: 8% of $60,000 is $4,800, so wages plus that estimated payroll load equal $64,800. It does not mean every employer should add exactly 8%. Use your actual state rates and include non-tax costs separately.

Don’t forget employee turnover cost math

Payroll is only part of the cost of keeping a position filled. Turnover can add recruiting, onboarding, training, overtime, and lost productivity costs. A basic estimate is:

Turnover cost per departure = recruiting costs + onboarding and training costs + temporary coverage costs + estimated lost productivity

For example, say replacing an employee costs $2,000 in recruiting, $1,500 in onboarding and training, and $1,000 in temporary coverage. Add a conservative $2,500 estimate for lost productivity and the total is $7,000 per departure.

That is an estimate, not a universal benchmark. A role that takes months to fill or requires specialized training may cost much more. To avoid double-counting, write down which costs are included. If you’re assessing a retention program, compare the program’s annual cost with the turnover costs it could realistically reduce—not with the full salary of every employee who stays.

Free small business calculators: useful, but check the assumptions

Free payroll, paycheck, and employer-cost calculators can help with early planning. QuickBooks and Gusto offer payroll-related tools and resources; availability and features can change, so check the current product pages before relying on a particular calculator. Depending on the tool, you may be able to estimate a paycheck or get a rough sense of payroll costs.

These tools are best used as a first pass. Before you make a hiring or compensation decision, check whether the calculator includes:

The employee’s work state and any relevant local jurisdiction.
State unemployment contributions and whether your business’s assigned rate is included.
State disability or paid-leave contributions, and who pays them.
Wage limits, employer-size rules, and any state-specific exceptions.
Employee benefit deductions, retirement contributions, and other paycheck deductions.
Current tax-year rates and filing rules.

A calculator may also display an estimated take-home amount without accounting for every benefit deduction or the employee’s full tax situation. Compare its output with a sample pay statement and confirm the assumptions instead of treating the number as a guaranteed paycheck.

QuickBooks and Gusto: what to compare

QuickBooks and Gusto are payroll providers small businesses may consider when they want software to calculate payroll, manage filings, and support employee pay. Features, included services, state coverage, and pricing can change, so compare current plan details rather than relying on an old feature list.

When reviewing either provider, look beyond the headline monthly price. Check whether payroll tax filings and payments are included in your plan, whether there are per-employee charges, what fees apply to contractor payments or add-on benefits, and whether extra costs apply for multiple states. Confirm how the provider handles notices, amended filings, year-end forms, and support when a state account is set up incorrectly.

Software can help apply rules and track deadlines, but it cannot make a complicated worker-location question disappear. You are still responsible for providing correct employee and business information, reviewing payroll reports, and responding to agency notices. Before signing up, verify which services are included and which are optional or separately priced.

State resources to check before your first payroll

Use official state resources for current rates and filing requirements. A payroll provider’s guide can be a useful overview, but the state agency’s instructions are the source to confirm before you register, withhold, or remit taxes.

State department of revenue or taxation: income-tax withholding forms, deposit schedules, and filing instructions.
State unemployment insurance agency: employer registration, taxable wage limits, assigned rates, and contribution reports.
State labor department: wage-and-hour rules, paid-leave requirements, and employer notices.
State disability or paid-leave program agency: contribution rates, exemptions, and employee notices, where applicable.
Local tax authority: city or county withholding or payroll taxes, if relevant.

Keep the effective date in view. Rates, wage limits, forms, and deposit schedules can change from one year to the next. Save a copy or link to the official guidance you used so you can revisit the assumptions when rates update.

A practical checklist for estimating payroll in a new state

Confirm where the employee will physically work and where they live.
Register with the required state and local tax agencies before running payroll.
Identify employee withholdings separately from employer-paid taxes and contributions.
Check current state unemployment rates and wage limits for your business.

Look for paid-leave, disability, and local requirements that a generic estimate may omit.
Estimate take-home pay and total employer cost as separate calculations.
Review payroll software pricing, filing coverage, and state-specific support before choosing a plan.
Recheck official state resources when an employee changes work location or rules update.

The bottom line

Payroll taxes by state change because states—and sometimes local governments—set different withholding rules, unemployment contributions, wage limits, and paid-leave or disability requirements. Those differences affect both employee take-home pay and the employer’s true cost of hiring, but not in the same way.

Use free small business calculators from providers such as QuickBooks or Gusto to get an initial estimate, then verify the assumptions against current state resources. Budget for employer taxes separately from employee deductions, add benefits and operating costs, and treat turnover math as its own planning exercise. That gives you a more useful hiring number than a single generic payroll percentage.
