PSL on a pay stub stands for paid sick leave: wages your employer pays you for hours you didn’t work because you or a covered family member were sick, injured, or needed medical care. PSL in payroll is tracked under its own earnings code so it stays separate from regular hours, overtime, vacation, and other paid time off, which is why you see it broken out on your stub with its own balance.1U.S. Department of Labor. Sick Leave
What the PSL Line on Your Stub Represents
Two numbers usually sit under the PSL heading: hours used in the current pay period and the running balance available to you. That balance is money your employer already owes you if you get sick. On the company’s books, every accrued but unused hour sits as a liability until you spend it, it expires under a use-it-or-lose-it rule, or your employment ends.
The separate earnings code is not cosmetic. It lets payroll software calculate accruals correctly, apply the right tax withholdings, and produce the reporting employers need to comply with state and local sick leave laws. When you request sick time, the payroll clerk codes those hours as PSL, and that code drives everything downstream: gross pay, taxes, and the reduction in your available balance.
How You Earn PSL Hours
Most sick leave programs use one of two methods to give you hours.
Under the accrual method, you earn sick time incrementally as you work. The most common ratio is one hour of PSL for every 30 hours on the clock. A 40-hour week produces about 1.33 hours of sick leave, or roughly 69 hours over a full year before any cap applies. Payroll software runs the math automatically each pay period.
Under the front-loading method, your employer deposits a lump sum of hours at the start of the benefit year or on your hire anniversary, typically 40, 56, or 80 hours. There’s no running tally to watch: the balance is there on day one.
Many jurisdictions that require paid sick leave let employers pick either method. Federal contractors covered by Executive Order 13706 use the one-hour-per-30 rate, with an option to front-load at least 56 hours at the start of each accrual year.2eCFR. 29 CFR 13.5 – Paid Sick Leave for Federal Contractors and Subcontractors
Waiting Periods and Minimum Increments
Accrual often begins on your first day, but that doesn’t mean you can spend the hours immediately. Many state laws and employer policies impose a waiting period before new hires can draw on the balance. Ninety calendar days is the most common threshold. If you leave and get rehired by the same employer within 12 months, days worked before the separation typically count toward the waiting period so you don’t restart from zero.
Employers can’t always force you to burn a full day for a short appointment. Most state sick leave laws cap the minimum usage increment, commonly at one or two hours. Federal contractor rules set the ceiling at one hour, meaning a contractor cannot require you to use more than one hour at a time.2eCFR. 29 CFR 13.5 – Paid Sick Leave for Federal Contractors and Subcontractors
Caps, Carryover, and Forfeiture
Left alone, an accrual formula would let you stockpile unlimited hours. Most programs prevent that with an accrual cap that stops the balance from growing once it hits a set number, commonly between 40 and 80 hours. Once you hit the cap, no new hours post until you use some and your balance drops.
A separate usage cap limits how many hours you can actually spend in a single benefit year even if your bank is larger. An employer might allow an 80-hour carryover balance but restrict you to 40 hours of use per year. Having the hours and being allowed to spend them are two different things.
At year-end, one of two rules kicks in. Carryover lets unused hours roll into the next year, often up to a limit. Forfeiture, the use-it-or-lose-it rule, resets the balance to zero. Many state mandates require at least some carryover. Federal contractor rules require full carryover, and the carried-over hours don’t count against the next year’s accrual limit.2eCFR. 29 CFR 13.5 – Paid Sick Leave for Federal Contractors and Subcontractors
What You Can Use PSL For
The name understates what the benefit actually covers in most jurisdictions.
- Your own health: diagnosis, treatment, recovery, and preventive care like flu shots and annual checkups.
- Family care: caring for a sick child, spouse, parent, or other close family member. Many laws define family broadly enough to include grandparents, siblings, domestic partners, and in-laws.
- Safe time: nearly all state sick leave laws let you use accrued hours for needs related to domestic violence, sexual assault, or stalking, including seeking legal help, relocating, or attending court.
- Public health situations: if a health authority or your doctor determines your presence at work would endanger others because of a communicable disease exposure, sick leave covers the absence.
Doctor’s Notes
Employers can generally ask for medical documentation for longer absences, but many state laws and employer policies restrict this to absences longer than three consecutive days.
How PSL Is Taxed and Shown on Your W-2
When your employer pays PSL directly, the money is treated like any other wages. Federal income tax, Social Security tax, and Medicare tax all apply, and withholding works the same way it does for regular pay.3Internal Revenue Service. Publication 15-A (2026), Employer’s Supplemental Tax Guide
The rules shift when a third party, such as a disability insurance carrier, pays the sick leave on your employer’s behalf. The third-party payer handles withholding, and you can submit Form W-4S to request federal income tax withholding from those payments.4Internal Revenue Service. About Form W-4S, Request for Federal Income Tax Withholding from Sick Pay
For Social Security, the taxable wage base in 2026 is $184,500. Any combination of regular wages and sick pay above that limit is exempt from Social Security tax for the rest of the year. Medicare tax continues with no cap.5Social Security Administration. Contribution and Benefit Base
Taxable sick leave paid directly by your employer appears in Box 1 of your W-2 alongside regular wages. Nontaxable sick leave paid by a third party (because you funded the plan with after-tax dollars) shows up in Box 12 under Code J. When a third-party payer is involved, either the employer or that third party prepares the W-2 depending on how notification between them was handled.6Internal Revenue Service. 2026 General Instructions for Forms W-2 and W-3
Whether Your Employer Has to Offer PSL
No federal law requires private employers to provide paid sick leave. The Fair Labor Standards Act treats vacation pay, sick pay, and holiday pay as matters of agreement between employer and employee.7U.S. Department of Labor. Questions and Answers About the Fair Labor Standards Act (FLSA)
State and local law is where the real coverage sits. As of 2026, 21 states plus the District of Columbia mandate paid sick leave for private-sector employees, and many cities and counties add their own ordinances on top, sometimes with higher accrual rates or broader family definitions. Where a local rule is more generous than the state minimum, the employer must follow whichever is more favorable to the employee. Most of these laws share the same skeleton: a one-hour-per-30 accrual rate, a cap between 40 and 80 hours, and a covered-use list that reaches beyond personal illness to family care and safe time. The details diverge enough that PSL is configured based on where you physically work, not where the company is headquartered.
A separate mandate covers employees working on federal contracts under Executive Order 13706. Covered uses include physical or mental health needs, caring for a child, parent, spouse, or domestic partner, and absences related to domestic violence, sexual assault, or stalking.8GovInfo. Executive Order 13706 – Establishing Paid Sick Leave for Federal Contractors
How PSL and FMLA Overlap
The Family and Medical Leave Act gives eligible employees up to 12 weeks of unpaid, job-protected leave per year for serious health conditions, new-child bonding, and other qualifying reasons.9U.S. Department of Labor. Family and Medical Leave (FMLA)
FMLA protects your job, not your paycheck. The law allows either the employer or the employee to substitute accrued paid leave, including PSL, for the unpaid FMLA time. Many employers require it, so your sick leave bank runs down at the same time as your FMLA clock. You don’t get FMLA leave plus your full sick balance on top. They overlap. Hours coded as PSL during an FMLA absence still get taxed as regular wages and still reduce your available balance.
What Happens to Your PSL If You Leave
Unlike vacation pay, which many states require employers to cash out at separation, accrued sick leave almost never triggers a payout obligation. The FLSA is silent on the point, and as of 2026 no state specifically requires a cash payout of unused sick leave when you leave a job.7U.S. Department of Labor. Questions and Answers About the Fair Labor Standards Act (FLSA)
Most employers treat the balance as forfeited at separation. Many state sick leave laws, and the federal contractor rule under EO 13706, require reinstatement of your prior balance if you’re rehired within 12 months. If your employer bundles sick leave into a general PTO bank instead of tracking it separately, the payout rules for that combined bank may follow your state’s vacation pay laws, which can be more employee-friendly.
Retaliation Protections
Nearly every state and local paid sick leave mandate includes anti-retaliation provisions. These typically bar employers from firing, demoting, cutting hours, or otherwise punishing you for requesting or using earned sick time. Attendance policies that assign points or demerits for sick absences can violate those protections when the absence was for a covered reason. Remedies vary by jurisdiction and can include back pay, reinstatement, and per-violation fines. Employees usually file complaints with a state labor department, though some statutes also provide a private right of action.
