Payroll rules vary by state because state law layers on top of the federal wage, tax, and recordkeeping baseline, and compliance is tied to where each employee actually performs work rather than where the company is headquartered. The Fair Labor Standards Act sets minimum standards for wages, overtime, and recordkeeping, but most states go further in at least one area, and when federal and state rules conflict, employers must follow whichever standard benefits the worker more.1U.S. Department of Labor. Wages and the Fair Labor Standards Act A business with staff in three states is effectively running three different payroll compliance programs.
The Federal Baseline Every Employer Meets
Before state rules enter the picture, every employer owes the same set of federal payroll taxes on each employee’s wages. Employers and employees each pay 6.2% toward Social Security on wages up to a taxable base of $184,500 in 2026,2Social Security Administration. Contribution and Benefit Base plus 1.45% each toward Medicare with no cap. Employees earning above $200,000 individually (or $250,000 for joint filers) owe an additional 0.9% Medicare surtax, which employers withhold but do not match.
Federal unemployment tax (FUTA) runs 6.0% on the first $7,000 of each employee’s annual wages, though employers who pay state unemployment tax on time typically receive a credit of up to 5.4%, dropping the effective rate to 0.6%.3Internal Revenue Service.

FUTA Credit Reduction Federal income tax withholding runs off each employee’s Form W-4; if a new hire never submits one, the employer withholds as if the employee is single with no adjustments.5Internal Revenue Service. Topic No. 753, Form W-4, Employees Withholding Certificate
Withheld income tax and the employee share of FICA are “trust fund” money belonging to the government the moment they leave the paycheck. Diverting those funds to cover other expenses exposes any responsible officer or partner to the trust fund recovery penalty, assessed personally for the full unpaid amount plus interest.6Internal Revenue Service. Trust Fund Recovery Penalty
State Income Tax Withholding and Multi-State Employees
Most states require employers to withhold state income tax from wages. Nine states impose no personal income tax at all. The rest range from flat rates to progressive brackets with top rates above 10%, and each state publishes its own withholding tables and requires a separate withholding account registration.
Cross-border workers add another layer. About sixteen states have reciprocity agreements that let employees pay income tax only to their state of residence, even when they commute across a state line for work. Without reciprocity, an employee may owe tax to both the work state and the home state, though most states offer a credit for taxes paid elsewhere. The threshold for how many days a nonresident can work in a state before withholding starts differs from one state to the next, so employers with traveling staff or remote workers need to log work locations, not just home addresses.
State Unemployment Insurance
State unemployment tax (SUTA or SUI) is employer-funded and varies dramatically. Taxable wage bases start around $7,000 in some states and climb past $60,000 in others. The rate assigned to each employer depends on industry, payroll size, and claims history, with new businesses starting at a default rate until they build enough experience for an experience-based rate. Unlike FUTA, which behaves like a flat per-employee cost, state rates can swing significantly year to year based on claims activity.
Minimum Wage, Overtime, and Tips
The federal minimum wage has been $7.25 per hour since 2009, and the majority of states now set a higher floor. Where the state minimum exceeds the federal rate, the state rate governs.1U.S. Department of Labor. Wages and the Fair Labor Standards Act More than a dozen states index their minimum wage to a consumer price measure so it adjusts automatically each January. In 2026, state minimums in the highest-cost jurisdictions ranged from roughly $15 to over $17 per hour.
Federal overtime requires 1.5 times the regular rate for hours beyond 40 in a workweek.7U.S. Department of Labor. Overtime Pay Several states mandate daily overtime on top of that, requiring premium pay for hours beyond eight in a single day regardless of the weekly total. Some go further and require double-time when a shift passes twelve hours or when an employee works seven consecutive days. Daily overtime rules catch multi-state employers off guard more than almost any other state variation, because a 40-hour week can still generate overtime liability if the hours are stacked unevenly.
Underpaying minimum wage or overtime carries federal liquidated damages equal to the full amount of the unpaid wages, effectively doubling the bill,8Office of the Law Revision Counsel. United States Code Title 29 – 216 and many states stack their own penalties on top.
Tip Credits
Federal law lets employers pay tipped employees a direct cash wage of $2.13 per hour, applying a tip credit of up to $5.12 per hour to reach $7.25. If tips fall short, the employer must make up the difference.9U.S. Department of Labor. Fact Sheet 15: Tipped Employees Under the Fair Labor Standards Act State rules diverge sharply. Some allow a tip credit but set a higher cash wage floor; others have eliminated the tip credit entirely and require the full state minimum wage before tips are counted.10U.S. Department of Labor. Minimum Wages for Tipped Employees Restaurant and hospitality operators expanding into a new state should check this rule before signing a lease, because the gap between a $2.13 cash wage and a $16 cash wage rewrites the labor budget.
Exempt Salary Thresholds
The FLSA exempts executive, administrative, and professional employees from overtime if they earn above a minimum salary and meet specific duties tests. The federal salary floor is $684 per week ($35,568 annually). Several states set their own thresholds well above that, and an employee who falls below the applicable floor is non-exempt regardless of job title. Getting this wrong means back pay for every overtime hour worked, potentially reaching two or three years back.
Worker Classification
The classification question comes before any payroll rule applies: is the worker actually an employee? Misclassifying employees as independent contractors lets an employer skip withholding, FICA contributions, unemployment tax, and workers’ compensation coverage all at once, and when the classification is wrong, all of those obligations come due retroactively with penalties and interest.
The IRS evaluates three categories of evidence:11Internal Revenue Service. Independent Contractor (Self-Employed) or Employee?
- Behavioral control: whether the company directs how, when, and where the work gets done, or just defines the end result.
- Financial control: whether the company controls the business side of the arrangement, including payment method, tool ownership, and expense reimbursement.
- Type of relationship: whether there is a written contract, whether employee-type benefits are provided, and whether the work is a core part of the company’s regular business.
No single factor decides the outcome. Many states apply their own tests that are stricter than the federal one. Some use an “ABC test” that presumes a worker is an employee unless the hiring entity proves all three prongs of a narrow exception. A classification that holds up federally can still fail at the state level.
Pay Frequency and Payment Methods
Most states dictate how often employees must be paid. Weekly, biweekly, and semimonthly are the common cycles, and many states also cap the number of days between the close of a pay period and the actual payday, typically seven to fifteen days.
Payment methods are regulated too. Direct deposit is the default at most companies, but many states require employers to offer a paper check option or obtain written consent before making electronic payment mandatory. Payroll cards are legal in most states, but they generally must allow at least one free withdrawal per pay period so the employee can access their full wages in cash.12Consumer Financial Protection Bureau. Are There Fees to Use a Payroll Card Forcing workers onto a fee-heavy payroll card with no free withdrawal option can be treated as a wage-and-hour violation in some states.
Pay Stubs and Wage Notices
No federal law requires pay stubs, so state law controls entirely. The vast majority of states require itemized pay statements showing gross wages, each deduction, net pay, and the pay period dates. Some also require the employer’s legal name and address, the hourly rate, total hours worked, and accrued leave balances. For non-exempt employees, the stub should show the hourly rate and hours worked at each rate so the employee can verify overtime calculations. Where electronic stubs are allowed, states often require that the employee be able to print them or access them through a secure portal, and paper copies must generally be provided free on request.
A growing number of states also require a written wage notice at hire, disclosing the pay rate, overtime rate, regular payday, and employer’s legal identity. Updated notices must go out before any of those terms change. Penalties for missing or inaccurate stubs and hire notices accumulate on a per-employee, per-pay-period basis, which is how a technical defect can turn into a six-figure exposure.
Final Paychecks After Separation
Every state sets a deadline for the final check, and the deadline usually depends on whether the employee was fired or quit. Involuntary termination often triggers an immediate or next-business-day obligation. Voluntary resignations frequently allow payment by the next regularly scheduled payday, though some states shorten that window if the employee gave advance notice.
Missing the deadline can be expensive. A number of states impose waiting-time penalties that accrue daily at the employee’s daily rate for each day the check is late, sometimes running up to 30 calendar days. A worker earning $200 per day whose final check arrives three weeks late can generate over $4,000 in penalties on top of the wages owed.
Accrued Leave Payouts
Whether unused vacation or PTO must be cashed out depends on state law. Many states treat accrued vacation as earned compensation, which means the cash value belongs in the final paycheck and “use-it-or-lose-it” policies that forfeit unused leave at year-end or on separation are unenforceable. Other states allow forfeiture if the employer has a clear written policy. The rule to check is the one where the employee works, not where the company is based.
Wage Garnishment
Federal law caps garnishment for ordinary consumer debts at the lesser of 25% of disposable earnings or the amount by which weekly disposable earnings exceed 30 times the federal minimum wage (currently $217.50 per week).13Office of the Law Revision Counsel. United States Code Title 15 – 1673 Restriction on Garnishment Disposable earnings are what remains after legally required deductions like taxes, Social Security, and Medicare.14U.S. Department of Labor. Fact Sheet 30: Wage Garnishment Protections of the Consumer Credit Protection Act
Child support and alimony follow a different scale: up to 50% of disposable earnings if the employee supports another spouse or child, up to 60% if not, plus another 5% if payments are more than twelve weeks in arrears.14U.S. Department of Labor. Fact Sheet 30: Wage Garnishment Protections of the Consumer Credit Protection Act Child support withholding takes priority over almost every other type of garnishment, with a pre-existing IRS tax levy as the main exception. When multiple orders arrive, processing them in the wrong priority order can expose the employer to the displaced creditor.
Many states set garnishment limits that protect the employee more than the federal cap does, either through lower percentages or larger exempt amounts. Employers apply the law of the state where the employee works, and where the state limit is stricter, the state rule controls.
New Hire Reporting
Federal law requires every employer to report each new or rehired employee within 20 days of their start date to the state directory where the employee works.15Office of the Law Revision Counsel. United States Code Title 42 – 653a State Directory of New Hires The report must include the employee’s name, address, and Social Security number, along with the employer’s name, address, and federal employer identification number.16Administration for Children and Families. 17U.S. Department of Labor. Fact Sheet 21: Recordkeeping Requirements Under the Fair Labor Standards Act The EEOC separately requires three-year retention for payroll records under the Age Discrimination in Employment Act.18U.S. Equal Employment Opportunity Commission. Recordkeeping Requirements
State retention periods often run four to six years, and a few states go further for specific record categories. Because the longest applicable requirement controls, most payroll professionals default to a six-year retention policy across all records, including wage notices, deduction authorizations, and timekeeping data.
Records matter beyond compliance. When a wage-and-hour claim lands, the burden of proof often shifts to the employer to show what was actually paid. If the records are missing or incomplete, courts in many jurisdictions apply an adverse inference and presume the employee’s version of the disputed hours or wages is correct. A single recordkeeping gap can turn a defensible case into a settlement.
