Paycheck FAQs - Payroll Rules, Calculations, And Compliance
Paycheck FAQs
A paycheck is much more than a payment to an employee. Payroll professionals must understand wage and hour requirements, employee classifications, overtime, payroll tax withholding, deductions, garnishments, benefits, final pay requirements, recordkeeping, and state-specific payroll rules.
The Paycheck FAQs from Payroll Training Center provide practical answers to common questions about processing accurate and compliant employee paychecks.
Whether you are a payroll administrator, payroll specialist, HR professional, accountant, bookkeeper, controller, finance manager, or business owner, these FAQs can help you understand the rules and procedures involved in paycheck processing.
Common FAQs About Payroll Paychecks
If you are a small employer who outsources payroll, this is the page to start with. Understanding what happens between gross and net is what lets you spot an error before it becomes a penalty — and the liability for those errors stays with you, not with your provider, so make sure you know all of the rules!
What is a paycheck?
A paycheck is the payment an employer provides to an employee for compensation earned during a specific pay period. A paycheck may be delivered by paper check, direct deposit, payroll card, or another legally permitted payment method.
What information is needed to prepare a paycheck?
Payroll professionals may need information such as:
- Employee classification
- Pay rate
- Hours worked
- Overtime hours
- Bonuses or commissions
- Applicable benefits
- Employee tax information
- Authorized deductions
- Garnishments or levies
- Paid time off
- Applicable state and local requirements
Accurate information is essential to calculating the employee's pay correctly.
What is gross pay?
Gross pay is the employee's compensation before applicable taxes and deductions are subtracted. Gross pay can include regular wages, overtime, bonuses, commissions, and other forms of compensation.
What is net pay?
Net pay is the amount an employee receives after applicable taxes and deductions have been withheld from gross pay. Net pay is commonly referred to as take-home pay.
What is the difference between gross pay and net pay?
Gross pay is total earnings before anything is withheld — wages, salary, overtime, bonuses, and commissions. Net pay, or take-home pay, is what remains after taxes and other deductions. The gap between them is typically 25 to 35 percent for a typical employee, which is why employees who negotiate on gross frequently misjudge what will actually arrive.
What comes out of a paycheck, in what order?
Generally: pre-tax deductions such as qualifying benefit contributions, then federal income tax withholding, then Social Security and Medicare, then state and local income taxes, then post-tax deductions such as Roth contributions and most garnishments. Order matters because pre-tax deductions reduce the wages the tax is calculated on. Garnishment calculations use disposable earnings, which is its own defined figure.
What is FICA, and who pays it?
FICA is Social Security and Medicare tax, and both employer and employee pay it. The employee's share is 6.2 percent for Social Security and 1.45 percent for Medicare, and the employer matches both. An Additional Medicare Tax of 0.9 percent applies to wages above a threshold, and it is withheld from the employee only — there is no employer match on that portion.
Is there a limit on Social Security tax?
Yes. Social Security tax applies only up to the annual wage base, which is $184,500 for 2026, up from $176,100 in 2025. Once an employee's wages for the year exceed the base, Social Security withholding stops for the rest of the year. Medicare has no wage base — it applies to all wages.
How is federal income tax withholding calculated?
From the employee's Form W-4 and the applicable IRS withholding methods. The W-4 was redesigned in 2020 and no longer uses withholding allowances; it uses filing status, multiple-job adjustments, dependents, other income, deductions, and any additional amount requested. An employee who has not submitted a W-4 is withheld as single with no adjustments.
What is the Fair Labor Standards Act?
The Fair Labor Standards Act (FLSA) establishes federal requirements concerning areas such as minimum wage, overtime pay, recordkeeping, and youth employment for covered employees.
Payroll professionals should understand how FLSA requirements affect paycheck calculations. Payroll Training Center specifically identifies FLSA requirements as a fundamental part of paycheck administration.
What is minimum wage?
Minimum wage is the lowest wage an employer may generally pay a covered employee under applicable law.
Federal, state, and local minimum wage requirements may differ. When multiple requirements apply, employers must follow the applicable rules.
What is overtime pay?
Overtime pay is additional compensation required for qualifying hours worked beyond applicable limits.
Under the FLSA, covered nonexempt employees generally must receive overtime at not less than one and one-half times their regular rate for qualifying hours worked over 40 in a workweek. State and local requirements may impose additional protections.
How is overtime calculated?
For a covered nonexempt employee subject to the federal overtime standard, overtime is generally calculated using the employee's regular rate of pay and applicable qualifying overtime hours.
The calculation can become more complicated when employees receive bonuses, commissions, different pay rates, or other forms of compensation.
What is the regular rate of pay?
The regular rate is generally the rate used to determine overtime compensation for covered nonexempt employees under the FLSA. It can involve more than simply an employee's stated hourly rate because certain forms of compensation may need to be included in the calculation.
Are all employees entitled to overtime?
No. Overtime eligibility depends on employee classification and applicable federal, state, and local requirements. Certain employees may qualify for exemptions from federal overtime requirements if they satisfy applicable tests.
What is a payroll deduction?
A payroll deduction is an amount withheld from an employee's wages.
Deductions can be required by law, authorized by an employee, required under a court or administrative order, or associated with employee benefits.
What are common paycheck deductions?
Common deductions can include:
- Federal income tax
- Social Security and Medicare taxes
- State and local taxes
- Health insurance premiums
- Retirement plan contributions
- Wage garnishments
- Child support
- Other authorized deductions
Can an employer deduct money from an employee's paycheck?
Certain deductions may be permitted or required, while others may be restricted by federal, state, or local law. Payroll professionals should verify that a deduction is legally permitted and properly authorized before processing it.
What is a voluntary deduction?
A voluntary deduction is generally an amount an employee has authorized to be withheld from wages, such as certain benefit premiums or retirement contributions. The rules governing voluntary deductions vary by jurisdiction and deduction type.
What is an involuntary deduction?
An involuntary deduction is generally withheld because of a legal or regulatory requirement. Examples can include certain tax withholdings, garnishments, levies, and child support orders.
What is the difference between pre-tax and post-tax deductions?
Pre-tax deductions reduce taxable wages, so the employee pays less tax — typical examples are traditional 401(k) deferrals, health premiums under a Section 125 plan, HSA contributions through payroll, and FSA contributions. Post-tax deductions come out after tax is calculated and do not reduce taxable wages — Roth contributions, most garnishments, union dues in many cases, and after-tax insurance. Whether a deduction is pre-tax is a matter of law, not employer preference.
Why did an employee's take-home pay change when nothing else did?
The usual causes are hitting the Social Security wage base, a benefit enrollment or rate change, reaching a deduction goal such as a loan repayment, a change in year-to-date supplemental wage treatment, a new garnishment, a W-4 change, or a state or local rate change at the start of a year. Working through this list resolves the large majority of "my check is different" questions.
How do employee benefits affect a paycheck?
Benefits can affect both gross wages and paycheck deductions depending on the type of benefit and applicable tax rules. Examples include health insurance, retirement plans, cafeteria plans, flexible spending arrangements, and other benefits.
How do 401(k) contributions affect a paycheck?
An employee's 401(k) contribution generally reduces the amount of current compensation paid to the employee. The tax treatment depends on whether the contribution is traditional, Roth, or another type of contribution.
What are fringe benefits?
Fringe benefits are forms of compensation or benefits provided to employees in addition to regular wages. Some fringe benefits may be taxable, while others may qualify for favorable tax treatment under applicable rules.
Do fringe benefits have to appear on a paycheck?
The treatment depends on the type of benefit and applicable payroll and tax requirements. Payroll professionals should understand whether a benefit must be included in taxable wages or otherwise reflected in payroll records.
Are employers required to give employees a pay stub?
There is no federal pay stub requirement under the FLSA, though employers must keep accurate records of hours and wages. Pay stub obligations come from state law, and states differ on whether a statement is required at all, whether it may be electronic only, and what must appear on it. Several states impose penalties for non-compliant statements independent of whether wages were correct.
Can an employer require direct deposit?
It depends on the state. Some states permit mandatory direct deposit, some require employee consent, and some require that an alternative such as a paycard or paper check be offered. Where paycards are used, additional federal and state rules apply concerning fees and access to full wages without cost. Making direct deposit mandatory nationwide without checking state law is a common multi-state error.
How often must employees be paid?
Pay frequency is set by state law, not federal, and commonly ranges from weekly to semi-monthly, sometimes varying by employee type. Employers operating in several states often standardize on the most frequent schedule required among them. Changing pay frequency generally requires advance notice and, in some states, specific conditions.
What is the difference between semi-monthly and biweekly pay?
Biweekly is every two weeks — 26 pay periods a year. Semi-monthly is twice a month, such as the 15th and last day — 24 pay periods. Biweekly produces two months a year with three paychecks; semi-monthly does not. Salaried per-period amounts differ between the two, and overtime is harder under semi-monthly because pay periods do not align with workweeks.
What should an employer do if an employee was underpaid?
Correct it promptly — many states require payment of undisputed wages within a short window, and some impose penalties for late payment of wages regardless of intent. Do not wait for the next regular cycle if state law requires faster payment. Document the cause, and check whether the same error affected other employees, because single-employee errors are usually systemic.
Can an employer deduct an overpayment from a future paycheck?
Not automatically. Federal law permits recovery of overpaid wages, but state law frequently requires written employee authorization, limits the amount recoverable per period, or prohibits deductions that bring pay below minimum wage. A repayment agreement signed before the deduction is the safest approach, and it should specify amounts and timing.
What happens if a paycheck is wrong because the payroll provider made the error?
The employer is still responsible to the employee and to the taxing authorities. A provider's error may create a contractual claim against the provider, but it does not excuse late deposits, incorrect withholding, or unpaid wages. This is the central point for small employers: outsourcing payroll transfers the work, never the liability.
How long should payroll records be kept?
The FLSA requires payroll records be retained for three years and records on which wage computations are based for two years; IRS rules generally require employment tax records for at least four years after the tax is due or paid; and states impose their own periods, some longer. Practically, most employers adopt a single retention period of at least four years and apply it consistently.
