The payroll questions owners ask on repeat.
This page organizes 25 common payroll questions using current public guidance from the IRS, the U.S. Department of Labor, the Social Security Administration, and small-business reference material from the SBA. It is built for orientation, not legal advice.
- Use it to orient yourself before a first run, a cleanup project, or a payroll software rollout.
- Read the federal answer first, then confirm any state or local requirements that also apply.
- Use the source links when you need the official agency page behind the short answer.
Payroll answers are often federal first, state second, and fact-specific all the way through. The goal here is to make the first pass clearer, not to flatten the nuance.

Payroll Basics
Core orientation for what payroll is and what needs to be in place before the first run.
What is payroll, in plain terms?
Payroll is the process of calculating what workers are owed, withholding the required taxes, paying wages on schedule, depositing employment taxes, and maintaining the records and forms that support each pay cycle.
What do I need in place before I run my first payroll?
At a minimum, most employers need a payroll schedule, worker classification decisions, tax IDs, withholding details such as Form W-4 information, a way to track hours for nonexempt employees, and a process for tax deposits and wage reporting.
What is the difference between gross pay and net pay?
Gross pay is the employee’s pay before taxes and other deductions. Net pay is what remains after required withholdings and authorized deductions are taken out.
What should a business owner review every payroll cycle?
At a minimum, review worker classifications, hours, gross-to-net calculations, withholding inputs, overtime exposure, department or job coding, unusual deductions, and whether upcoming tax deposits or wage reports will be affected by the run.
Tax, Forms, and Deposits
Federal withholding, employment taxes, deposit timing, and required payroll forms.
What taxes does an employer usually handle through payroll?
At the federal level, employers generally handle federal income tax withholding, Social Security and Medicare taxes, and federal unemployment tax. State and local payroll tax requirements may also apply depending on where the business and employees are located.
What payroll form should a new employee complete for federal withholding?
A new employee should generally complete Form W-4 so the employer can withhold the correct amount of federal income tax from wages.
What if an employee does not submit a valid Form W-4?
If an employee does not give you a properly completed Form W-4, the IRS says you must generally withhold federal income tax as if the employee is single or married filing separately, with no other adjustments reflected.
How is federal income tax withholding calculated?
Federal income tax withholding is generally based on the employee’s Form W-4, the wage amount, the payroll period, and the withholding methods and tables published by the IRS.
What are Social Security and Medicare taxes in payroll?
These are federal employment taxes commonly called FICA taxes. Employers generally withhold the employee share from wages and also owe an employer share under the federal employment tax rules.
What is FUTA?
FUTA is the federal unemployment tax. It is an employer tax used to help fund unemployment systems and is generally handled separately from employee wage withholding.
When do I have to deposit payroll taxes?
Federal employment tax deposit timing depends on the employer’s deposit schedule and liability level. IRS guidance for Forms 941 and 944 generally places employers on either a monthly or semiweekly deposit schedule, with special rules for very small or next-day liabilities.
How do I know whether I file Form 941 or Form 944?
Most employers file Form 941 quarterly, while some small employers file Form 944 annually if the IRS tells them they are eligible. The correct return depends on how the business is set up for federal employment tax reporting.
When are Forms W-2 due?
Employers generally must furnish Form W-2 to employees and file Copy A of Forms W-2 with Social Security, together with Form W-3 when required, by the applicable annual deadline for wage reporting.
What is Form W-3, and when would I use Form W-2C?
Form W-3 is the transmittal that accompanies W-2 wage reporting to Social Security. If you discover an error on a previously filed W-2, you generally use Form W-2C to correct the wage and tax information.
Classification, Overtime, and Hours
Worker status, exempt versus nonexempt rules, overtime, and compensable time questions.
How do I know whether a worker is an employee or an independent contractor?
For federal tax purposes, the IRS looks at the overall relationship using common-law factors tied to behavioral control, financial control, and the relationship of the parties. Businesses should classify workers carefully, because the payroll tax and wage-law consequences differ materially between employees and contractors.
Who is entitled to overtime pay?
Covered nonexempt employees must generally receive overtime pay for hours worked over 40 in a workweek at not less than one and one-half times their regular rate of pay.
Does being salaried automatically make someone overtime-exempt?
No. Salary alone does not automatically remove overtime obligations. Exemption depends on both the salary basis rules and the employee’s actual duties under applicable wage-and-hour law.
Does working on a holiday or weekend automatically require overtime?
Not by itself under federal law. The Department of Labor explains that overtime is generally tied to hours worked over 40 in a workweek, not simply to whether the work happened on a weekend, holiday, or rest day.
What counts as hours worked for payroll purposes?
Hours worked can include time the employee is required to be on duty, time the employer suffers or permits work to happen, and other compensable work time under the FLSA. Correct payroll depends on accurate time capture, not just scheduled hours.
Do I have to pay for travel time or work-related training time?
Some travel time and training time can be compensable, depending on the facts and the applicable wage rules. For example, the Department of Labor notes that travel during normal work hours is generally compensable, and work-related time cannot be ignored simply because it occurs away from the normal workstation.
Can I reclassify someone as a contractor just to reduce payroll tax costs?
No business should treat worker classification as a tax-saving shortcut. IRS and SBA guidance both caution that worker classification must follow the actual facts of control and independence, not the outcome the business would prefer.
Records, Corrections, and State Rules
Recordkeeping expectations, fixing mistakes, and where state law still matters.
What payroll records do I need to keep?
Under federal wage-and-hour rules, employers generally need accurate records about the employee and data about hours worked and wages paid. The exact record set varies by worker type and applicable law, but the records must be complete enough to support pay calculations and compliance.
How long should payroll records be kept?
Under the Fair Labor Standards Act recordkeeping guidance, employers generally must keep payroll records for at least three years, and records used to compute wages typically for at least two years. Tax record retention may require longer review depending on the record and issue.
What should I do if I make a payroll mistake?
Correct it promptly, document what changed, and update any affected tax filings or wage reports. Depending on the type of error, that may mean correcting pay records, withholding, employment tax returns, or year-end wage statements.
Does federal law set every payroll timing rule, like pay frequency or final pay timing?
No. Federal law covers core wage, overtime, and recordkeeping issues, but pay frequency, final pay timing, and some paycheck practices are often driven by state law. Businesses should confirm those rules for every state where they employ people.
