PTO accrual is the method by which employees earn paid time off gradually over a period of work, such as a set number of hours per pay period or per hour worked, rather than receiving the full annual allotment at once.
Under an accrual system, an employee earns paid time off incrementally. Common designs credit a fixed number of hours each pay period, award hours based on hours actually worked, or accrue at a rate that increases with tenure. The alternative is a lump-sum or front-loaded grant, where the full annual balance is available on the first day of the year. Accrual spreads the employer's liability across the year and limits how much time a new or departing employee can take beyond what they have earned.
Plan design details matter as much as the rate. Decide whether accrual continues during unpaid leave, whether it applies to overtime hours, whether part-time employees accrue proportionally, and whether unused time carries over or is capped. A common approach uses an accrual cap that stops further earning until the employee uses time, which is permitted in most states, as opposed to a use-it-or-lose-it forfeiture, which several states prohibit.
State law, rather than the federal FLSA, drives the biggest risks. Some states treat accrued vacation as earned wages that must be paid out at termination and cannot be forfeited. Mandatory paid sick leave laws often set minimum accrual rates, carryover rules, and waiting periods that override a more restrictive company policy. If you operate in multiple states, track balances by bucket rather than pooling everything.
No. A cap stops further earning once the balance reaches a set level and resumes when the employee uses time, which most states permit. A use-it-or-lose-it rule wipes out time the employee already earned at year end, and several states prohibit that outright.
It depends on the state. Some states treat accrued vacation as earned wages that cannot be forfeited and must be paid in the final check, while others follow the written policy. Because the answer varies, the policy language and the state of employment both matter.
Whether accrual continues during unpaid leave, whether overtime hours generate accrual, whether part-time employees accrue proportionally, and how carryover or caps work. Multi-state employers should also track balances by bucket rather than pooling them, since mandatory sick leave rules can override a more restrictive company policy.
