Compensated absences accounting is governed by ASC 710-10, which requires an employer to record a liability for earned-but-unused paid time off when four conditions are all met: the time was earned through past service, the right vests or accumulates, payment is probable, and the amount can be reasonably estimated. Miss the accrual and you overstate profit while hiding a real cash obligation. Get it right and the expense lands in the period the employee earned the benefit, not the period they finally take the trip.
What Counts as a Compensated Absence
The term covers any employer-paid absence where the employee isn’t working but still gets paid. Vacation is the common case. Sick leave, personal days, paid holidays, sabbaticals, and jury duty pay all fall inside the same framework. Whether you accrue depends on two features of the benefit.
A benefit vests when the employee has a right to cash payment for unused time even after leaving the company. If your policy pays out unused vacation at termination, that vacation is vested. A benefit accumulates when unused time carries into future periods instead of expiring. Many vacation policies allow rollover up to a cap, which makes those hours both accumulating and vesting. These two features drive almost every treatment decision below.
The Four Conditions in ASC 710-10-25-1
All four must be satisfied before accrual is required. If one fails, the accrual is not mandatory, though it may still be permitted.
- Services already rendered. The employee’s right to the paid time must come from work already performed, not from future service they haven’t delivered yet.
- Rights vest or accumulate. The benefit either carries forward to future periods or entitles the employee to a cash payout on separation. If unused time simply expires each period with no payout, this condition fails.
- Payment is probable. The employer is likely to actually pay the benefit out. For vested vacation, this is almost always met. For nonvesting sick leave, this is often why the standard doesn’t require accrual.
- The amount can be reasonably estimated. The employer can calculate a reliable figure. A company without enough history to estimate reliably defers the accrual until it can.
That fourth condition is where most deferrals happen. A new PTO policy may not have enough turnover and usage data to support an estimate. Once the data exists, the accrual kicks in for all the earned-but-unused time already on the books.
How to Measure the Liability
The liability equals the amount the employer expects to pay when the time is eventually used or cashed out, at the pay rate expected to be in effect at that time. In practice most companies use current pay rates as the best available estimate, adjusting for scheduled or contractual increases that are already known.
Payroll Tax Add-Ons
Base wages are only part of the number. Employer-side payroll taxes triggered by the eventual payout belong in the estimate. Social Security tax is 6.2% on wages up to $184,500 for 2026, and Medicare adds 1.45% with no cap.1Social Security Administration. Contribution and Benefit Base Federal unemployment tax applies at 6.0% on the first $7,000 of each employee’s annual wages, though most employers receive a credit that reduces the effective rate to 0.6%.2Internal Revenue Service. Topic No. 759, Form 940, Employers Annual Federal Unemployment Tax Return State unemployment taxes vary. If your policy continues health insurance or other fringe benefits during the absence, those costs belong in the estimate too.
Turnover and Timing
Not every accrued hour will be paid out the same way. Employees who leave take a lump-sum payout if the benefit vests. Employees who stay draw their balance down slowly. Historical turnover data refines the estimate and determines how the liability splits between current and noncurrent on the balance sheet.
Journal Entries
Recording the accrual is simple. When employees earn compensated absence time, debit a compensation expense account and credit a liability account, often called Accrued Compensated Absences or Accrued PTO. The expense hits the income statement in the period the employee earns the benefit, not the period the time is taken. When the employee later uses the time or receives a payout, reverse the liability: debit Accrued Compensated Absences, credit cash or payroll payable. If the pay rate rose between accrual and payout, the difference is additional compensation expense at that point.
How Each Leave Type Is Treated
Vacation and General PTO
Vacation is the textbook accrual case. Most policies make vacation both accumulating and vesting, which satisfies all four conditions. The full balance of earned-but-unused vacation must be accrued. Policies with rollover caps still require accrual up to the cap.
Sick Leave
Sick leave gets special treatment under ASC 710-10-25-7. Even when sick leave accumulates year to year, if it does not vest, accrual is not required. The reasoning is practical: usage is hard to predict and the amounts for nonvesting sick leave are unlikely to be material. You expense the cost when the employee calls in sick.
The treatment flips when sick leave does vest. If your policy pays out unused sick time at termination or retirement, accrue it the same way as vacation. The same applies when employees can routinely use sick days for non-illness reasons, because the benefit then functions like general PTO regardless of the label.
Sabbatical Leave
Sabbatical treatment depends on the purpose of the leave. When a sabbatical rewards past service with unrestricted time off, such as three months of paid leave after ten years, accrue the cost ratably over the entire service period the employee works to earn it. Each year, one-tenth of the expected sabbatical cost is expensed.
When the sabbatical exists to benefit the employer rather than reward past service, the analysis changes. A research sabbatical where the employee is expected to return and apply what they learned is tied to future service. That cost is generally expensed during the leave or over the required post-leave service period, not accrued in advance against past service.
Paid Holidays
Holidays are the easy category. They don’t accumulate (you can’t bank an unused holiday) and don’t vest (no one gets paid for holidays they didn’t take). The second condition fails, so no advance liability is recorded. The cost is expensed in the pay period the holiday falls in.
Does Unlimited PTO Create a Liability?
If employees have no defined bank of hours, there is nothing to accumulate and nothing to vest. The second condition fails and no liability is recorded. That is one reason some employers adopt unlimited PTO.
The simplicity comes with risk. If the “unlimited” policy functions like a traditional plan in practice, with informal caps, manager-imposed limits, or employees consistently taking similar amounts each year, regulators and courts may treat it as a disguised accrual plan. Multi-state employers face additional exposure because state paid sick leave laws often require tracking specific hour balances regardless of the broader label. An unlimited vacation policy doesn’t automatically satisfy a state mandate for 40 hours of trackable sick leave.
State Payout Laws Can Force Vesting
Whether vacation vests isn’t always a matter of company policy. Roughly 20 states require employers to pay out unused vacation or PTO at termination, even when the employer’s written policy is silent or says otherwise. California, Colorado, Massachusetts, and Nebraska mandate full payout by law. In those states, accrued vacation is legally vested regardless of what the handbook says, and the second accrual condition is automatically met.
In the remaining states, payout obligations depend on the written policy or employment contract. If no policy promises payout, there is no obligation. But if a company has established a written policy or past practice of paying out unused time, many of these states treat that as enforceable.
The accounting consequence is that companies in mandatory-payout states cannot avoid the accrual by tweaking internal policy. State law overrides. Multi-state employers need to track accruals by jurisdiction, because the same PTO policy can create a vested liability in one state and a nonvested benefit in another.
Balance Sheet Presentation and Disclosures
Split the total compensated absence liability between current and noncurrent. The current portion is the amount expected to be used or paid out within twelve months, or the company’s operating cycle if longer. Everything beyond that horizon is noncurrent.
If an employee has 200 hours of accrued vacation and historical patterns suggest 80 hours will be used in the next year, those 80 hours sit in current. The remaining 120 are noncurrent. The split matters because it feeds the current ratio and working capital figures lenders and investors watch.
Financial statement notes must disclose the compensated absence policy, including how benefits accumulate, vest, and are forfeited. If accrual has been deferred because the amount cannot be reasonably estimated, disclose that too. The point is to let readers understand the recorded number and judge the risk that actual payouts will differ.
FMLA and Military Leave Interactions
FMLA leave is unpaid by default, but employers can require employees to substitute accrued paid leave for the unpaid FMLA period, and employees can choose to do so on their own. When paid leave runs concurrently with FMLA, the employee receives regular pay and the leave counts against the FMLA entitlement at the same time.3U.S. Department of Labor. FMLA Frequently Asked Questions If your company requires employees to exhaust vacation and sick leave during FMLA, the accrued liability draws down faster than historical patterns would predict. Periods of high FMLA utilization can distort the current-versus-noncurrent split and the accuracy of prior estimates.
Military leave under USERRA has its own rule set. Returning service members are not automatically entitled to back vacation for the time they were away. If the employer provides vacation accrual to employees on comparable unpaid leaves of absence, service members on military leave must receive the same benefit.4eCFR. 20 CFR 1002.150 Employers must also allow service members to use vacation credits earned before deployment if the employee requests it, but cannot force the employee to burn vacation during military leave, with a narrow exception for company-wide mandatory shutdowns.5U.S. Department of Labor.
