Federal Credit Hours: Carryover Cap, Payout, and Limits

Federal credit hours are voluntary extra hours that an employee on a flexible work schedule chooses to work beyond the basic work requirement, then uses later to shorten another workday or workweek. They exist under the Federal Employees Flexible and Compressed Work Schedules Act of 1982, and the number that governs the whole system is 24: that is the most a full-time employee can carry from one biweekly pay period into the next.¹ Everything else about how you earn them, when you cannot, and what happens when you leave follows from a handful of specific rules.

Who Is Eligible

You must be officially assigned to a flexible work schedule. The statute defines credit hours as hours “within a flexible schedule established under section 6122” that go beyond your basic work requirement and that you elect to work.² Employees on a compressed schedule such as 4/10 or 5-4/9 fall under a different part of the law and cannot earn or use credit hours, even though both schedule types sit under the Alternative Work Schedule umbrella.

Full-time and part-time employees are both eligible if their agency’s policy or collective bargaining agreement permits it.³ Some agencies limit the program to certain offices where extra flexibility will not disrupt operations.

Members of the Senior Executive Service are excluded even when they participate in an agency’s Alternative Work Schedule program. OPM treats credit hours as a form of premium pay, and SES members are not eligible for premium pay.⁴

An agency head who finds that a flexible schedule is substantially disrupting operations or driving up costs can restrict arrival and departure times, limit credit hour use, or remove employees from the program.⁵

How You Earn Credit Hours

Credit hours must be voluntary. You choose to work them. Your supervisor cannot order extra hours and label them credit hours instead of paying overtime.³ If a manager directs the work, it is overtime, and the normal overtime pay or compensatory time off rules apply.

The rate is one for one: an hour of voluntary work beyond your basic requirement equals one credit hour. Federal law sets no daily cap on how many you can earn in a single day, but agencies typically do. Most agencies also require the work to fall within designated flexible time bands (for example, 6:00 a.m. to 6:00 p.m.) and to have supervisory approval in advance.³

The 24-Hour Carryover Cap

A full-time employee can carry a maximum of 24 credit hours from one biweekly pay period into the next. A part-time employee’s cap is one-quarter of the biweekly basic work requirement. If you are part-time and scheduled for 60 hours over two weeks, your carryover limit is 15 hours.¹

Anything above the cap at the end of a pay period is forfeited. There is no authority to pay you for the excess and no exception to the cap. Watch your balance during the pay period rather than banking hours you cannot realistically use or carry.

When You Cannot Earn Credit Hours

Several situations look like they should generate credit hours but do not. The common thread is the voluntary-work requirement.

Travel

Travel is ordered by the agency, so travel time on its own does not produce credit hours. A narrow exception applies if you perform actual productive work while traveling, such as drafting a report on your laptop during a flight. The work must be supervisor-approved, performed during hours when your agency’s flexible schedule permits credit hours, and beyond your basic work requirement.³ Sitting on a plane does not count. If the agency orders work during travel time beyond your basic requirement, that triggers overtime pay, not credit hours.

Training

Agency-required training is not voluntary work. Agencies may temporarily place you on a standard eight-hour, five-day schedule during a training period, which removes the flexible schedule altogether for that time. Any schedule change has to be announced before the administrative workweek begins.³

Holidays

You cannot earn credit hours simply for working during your holiday hours. If your agency’s policy or union agreement allows it, a supervisor may approve credit hours for holiday work that exceeds your basic requirement.³ Few agencies permit it in practice, so check your local policy first.

Credit Hours vs. Overtime and Premium Pay

Credit hours and overtime are mutually exclusive for the same block of time. OPM states directly that no overtime pay or compensatory time off may be paid when employees earn credit hours.³ The line between them is whether the work was voluntary or ordered.

Night differential and Sunday premium pay are also off the table. Night pay applies only to regularly scheduled night work, and credit hours are by definition not regularly scheduled. Using credit hours to skip a night shift does not entitle you to night pay for the hours you were absent. Sunday premium pay works the same way: it requires actually working a regularly scheduled Sunday tour, which credit hours cannot satisfy.³

Requesting and Tracking

Both earning and using credit hours run through your agency’s electronic time and attendance system. Many agencies use platforms like WebTA, which has dedicated transaction codes for credit hours earned and credit hours used.⁶ Different agencies use different systems, but the pattern is similar: pick the correct code, enter the date and duration, and route the entry to your supervisor for approval.

To earn credit hours, most employees submit a request before performing the work, listing the date, the hours planned beyond the basic requirement, and a short description of the task. Time is typically tracked in 15-minute increments. Once the supervisor approves, the hours land in your balance.

To use credit hours, you submit a separate request in the same system, selecting the “credit hours used” code and specifying the absence. The system checks your balance to confirm coverage. The approval flow resembles annual leave, though the hours come from your own voluntary work rather than an accrual. If your agency still uses paper, OPM Form 71 is the standard leave request document.⁷

Payout on Separation, Transfer, or Program Change

When you leave federal service, transfer to another agency, or move to a position that does not offer a flexible schedule, your agency must pay you for unused credit hours at your current rate of basic pay. The payout is capped at 24 hours for full-time employees and one-quarter of the biweekly basic work requirement for part-time employees.¹ Anything above those caps is not paid.

Transfers between federal agencies are treated like separations for this purpose. Your balance does not follow you. The losing agency pays out up to the statutory maximum, and you start fresh at the gaining agency.³ The payment usually appears in your final salary or as a separate lump sum. For an employee earning $45 per hour with a full 24-hour balance, the payout is $1,080 before taxes.

What a Shutdown Does to Your Balance

Employees designated as “excepted,” meaning they keep working during a lapse in appropriations, may earn credit hours for approved voluntary work beyond their basic requirement. No employee may use credit hours during a shutdown.⁸

The pain arrives at the pay period boundary. If you had planned to burn hours during the shutdown and could not, and your balance sits above 24 at period’s end, the excess is gone. OPM has confirmed there is no authority to pay for excess credit hours and no exception to the carryover cap, even when a shutdown made using them impossible.⁸ If a shutdown looks likely, spend down your balance before the lapse.

Recordkeeping and the Falsification Risk

Because credit hours are self-initiated and often worked outside core hours, accurate records are your responsibility. Falsifying time and attendance entries, including credit hour entries, is treated as a serious integrity offense across federal agencies. Penalties for a first offense range from reprimand to removal, and a second offense almost always results in removal. Falsification is defined broadly: knowingly providing false information or withholding information with intent to deceive, and reckless disregard for accuracy can also qualify.

Even honest errors can create problems if they form a pattern. If your supervisor cannot verify that you actually worked during the hours you claimed, those credit hours can be disallowed after the fact, which can turn an approved absence into unauthorized leave. Keep brief notes on what you worked on during credit hour periods so you can back up your entries if questioned.
