Nonprofit Timesheet Requirements: FLSA and Uniform Guidance

Nonprofit timesheet requirements come from two places at once: the Fair Labor Standards Act, which tells every employer what payroll data to keep, and the federal Uniform Guidance, which tells grant recipients how to prove that staff time charged to an award was actually spent on that award. A compliant timesheet captures the FLSA’s required hours-and-wages data for every non-exempt worker, and for anyone whose salary hits a federal grant, it also breaks hours down by funding source and carries both an employee and a supervisor signature.

What Has to Be on the Timesheet

A well-designed nonprofit timesheet does double duty for payroll and for grant compliance on a single form. At minimum it should include:

Employee identification: full name, employee ID, and department or position.
Pay period start and end dates.¹
Daily hours broken out by project code, allocated to the correct grant, program, or administrative category.
Daily totals and a weekly or pay-period total that accounts for all compensated activity.
The employee’s signature and date, certifying that the reported hours are accurate.
The supervisor’s signature and date, verifying the work was performed as described.²

Behind the timesheet, payroll records also need to carry the data points the Department of Labor requires for each non-exempt worker: Social Security number, address, birth date if under 19, sex and occupation, the day and time the workweek begins, hours worked each day, total weekly hours, pay rate, total earnings, deductions, total wages paid, pay period covered, and date of payment.³ Most of that lives in the payroll system; the timesheet feeds the hours in.

The dual-signature line matters more than it looks. The employee’s signature attests that the hours are truthful. The supervisor’s signature confirms firsthand knowledge that the work actually happened. Auditors look for both, and a missing supervisor signature on a stack of timesheets can undermine an entire grant’s personnel charges.

Two Rulebooks: FLSA and the Uniform Guidance

Under the Fair Labor Standards Act, every covered employer must keep records for each non-exempt worker showing hours worked each day, total hours for the workweek, and wages paid.⁴ The law does not require a specific form, only specific data.

The point that trips up nonprofit managers: the FLSA only requires detailed time tracking for non-exempt hourly employees, but grant compliance rules require it for everyone charged to a federal award, including salaried exempt staff. A salaried program director whose entire salary hits a federal grant still needs time documentation showing that work was actually performed on grant activities.

That second layer comes from 2 CFR 200.430, which governs how personnel costs get charged to federal grants. Salary and wage charges must be based on records that accurately reflect the work performed and that reasonably reflect the total activity the employee is compensated for, not exceeding 100 percent. The records must be supported by internal controls giving reasonable assurance that charges are accurate, allowable, and properly allocated, and they must be part of the organization’s official records and follow its established accounting policies.⁵

Budget estimates alone do not qualify as support for charges to federal awards. Estimates can be used for interim accounting only if they produce reasonable approximations, significant workload changes are recorded promptly, and the organization performs after-the-fact reviews reconciling interim charges with actual work performed.⁵ Start with an estimate if you must, but true it up with actual data before final reporting.

Allocating Hours Across Grants and Programs

When an employee works on more than one federal award, or splits time between a federal award and non-federal activities, the records must support how their salary is distributed among those specific activities.⁵ The same applies to employees splitting time between direct grant work and indirect cost activities, or between allowable and unallowable activities.

In practice, an outreach coordinator who spends mornings on a federal substance abuse prevention grant and afternoons on a state-funded literacy program needs to record those hours separately, each block coded to the correct funding source. Organizations typically assign internal project codes for each grant, program, and administrative function, and employees select the appropriate code when logging each block of time.

Getting these allocations right prevents commingling of funds, one of the most common audit findings. When an auditor sees eight hours logged to a grant with no breakdown of what those hours went to, the entire charge becomes suspect. Train staff on which codes apply to their work, keep reference materials accessible, and review coded timesheets before they reach the finance department.

Completing and Submitting the Timesheet

Record hours as the work happens rather than reconstructing a week from memory. Contemporaneous records are far more credible to auditors and far less prone to error. A timesheet filled out every Friday afternoon from memory almost always rounds in ways that don’t reflect reality. Organizations that struggle with this often move to daily logging requirements or use software that prompts employees at the end of each day.

Employees generally get project codes and tracking forms from their HR portal or a department supervisor, and reference materials like grant award notices and project descriptions help clarify which code applies to which task. When in doubt, ask before logging hours to the wrong code rather than fixing it after the fact.

Once completed, the employee signs the timesheet and it moves to a supervisor for review and countersignature. After both signatures are in place, it goes through the payroll system or a secure digital platform. Finance then performs a compliance review, checking that grant-coded hours align with approved budgets and that total hours across all funding sources reconcile. Only after that review does payroll process compensation. The workflow is built so every dollar paid can be traced back to a verified, coded time record.

Electronic Timesheets and Digital Signatures

Digital timekeeping is fully valid. The federal ESIGN Act provides that a signature or record cannot be denied legal effect solely because it is in electronic form.⁶ An electronic timesheet with a digital signature carries the same weight as an ink-on-paper one.

The system itself has to hold up, though. The IRS requires electronic storage systems to include controls that prevent unauthorized creation, alteration, or deletion of records. Records must be indexed and retrievable, reproductions must be clearly legible, and the organization must maintain the hardware, software, and personnel needed to produce records on request during an examination.⁷ If you change timekeeping platforms, either migrate the old records or keep the old system accessible. Records stored in a format you can no longer open are treated as destroyed.

How Long to Keep Timesheets

Three retention rules overlap. Follow whichever is longest for a given record.

Under federal labor law, basic payroll records must be kept for at least three years. Work-time schedules and supplementary records, including daily and weekly hours-worked tables, must be preserved for at least two years.⁸

For federal grant records, the Uniform Guidance requires retention for three years from the date you submit your final financial report. For awards renewed quarterly or annually, the three-year clock starts from the date of the most recent report. If litigation, an audit finding, or a claim involves the records, keep them until the matter is fully resolved, even if that extends past three years.⁹

The IRS requires employment tax records for at least four years after the tax becomes due or is paid, whichever is later.¹⁰ Since timesheets feed into payroll and tax calculations, the safest floor is four years, extended as needed while any grant or audit period is still open.

What Noncompliance Costs

Penalties range from awkward to severe.

On the labor law side, a willful violation of the FLSA’s recordkeeping and wage provisions can bring a criminal fine of up to $10,000, imprisonment for up to six months, or both. Imprisonment only applies to repeat offenders who have already been convicted of a prior FLSA violation.¹¹ Even without prosecution, employers who fail to keep adequate records face back pay liabilities and liquidated damages in wage disputes, and the lack of records often shifts the burden of proof to the employer.

For grant-funded organizations, the Uniform Guidance lets federal agencies disallow costs that are not properly documented. If an auditor determines that personnel charges to a grant lacked adequate time records, the nonprofit may have to repay those amounts. Repeated or severe problems can lead to suspension of current awards or denial of future funding.

The sharpest penalty is the False Claims Act. Knowingly submitting false time records to support charges on a federal grant can trigger civil penalties of $14,308 to $28,619 per false claim, plus three times the government’s actual damages.¹²¹³ Those per-claim amounts add up quickly when each falsified timesheet is treated as a separate claim. Federal prosecutors and whistleblowers have brought False Claims Act cases against nonprofits for inflated or fabricated time records on grant-funded programs.

A Note on Volunteers

Volunteers do not submit traditional timesheets, but their hours may still need documenting if the nonprofit uses volunteer time as a matching contribution for a federal grant. Under the Uniform Guidance, volunteer services from professionals, technical personnel, and other labor can count toward cost-sharing requirements, but only if the services are necessary for the program and properly valued.¹⁴

Valuation is specific. Volunteer rates must be consistent with what the organization pays its own employees for similar work. If there are no comparable employees, the rates must reflect the going market rate in the area. Reasonable fringe benefits can be included. All in-kind contributions must be documented using the same methods the organization uses for its own internal records, and the value must be verifiable.¹⁴
