1. Introduction: What is Form 13424-L?

IRS Form 13424-L, officially titled the Statement of Grant Expenditures (and often accompanied by Narrative Explanations), is an administrative financial accounting document published by the Internal Revenue Service (IRS). The IRS is a federal bureau operating under the United States Department of the Treasury responsible for administering the tax code and managing public tax programs.

Unlike personal tax returns filed by wage earners or business tax returns filed by commercial enterprises, Form 13424-L is an institutional expenditure report. It is administered independently by the Taxpayer Advocate Service (TAS) through the national Low Income Taxpayer Clinic (LITC) Program Office.

Under Section 7526 of the Internal Revenue Code, the federal government awards matching grants to qualifying non-profit organizations and law schools that represent low-income taxpayers in disputes with the IRS. Form 13424-L is the mandatory financial report used by clinics to show how federal grant funds and matching funds were spent during the operating year.

2. Purpose of the Form

When an organization receives an LITC grant, it submits a projected budget on Form 13424-J outlining its planned expenses. However, federal grant rules under Title 2 of the Code of Federal Regulations require grantees to account for the funds they spend.

Under federal statute, LITC awards are matching grants that require a strict dollar-for-dollar match. If a clinic receives $100,000 in federal money, it must contribute at least $100,000 in non-federal matching funds. Form 13424-L exists to prove that the organization met this mandatory 1:1 matching ratio using allowable cash or in-kind contributions.

Form 13424-L compares your approved budget against your actual spending across standardized cost categories such as personnel, travel, equipment, and supplies. It provides federal grant analysts with the documentation needed to ensure that public funds were spent reasonably, lawfully, and in direct support of low-income taxpayer representation.

3. Who Needs to File This Form

Form 13424-L is an institutional compliance document. It must be completed and submitted by organizations currently operating an active, grant-funded Low Income Taxpayer Clinic, including:

Legal Aid Societies: 501(c)(3) civil legal service programs managing an active LITC matching grant.
Academic Clinics: Law school, business school, and accounting clinical programs that receive federal LITC funds to supervise students representing taxpayers.
Community Non-Profit Clinics: Independent non-profit advocacy organizations funded to provide controversy representation or English as a Second Language (ESL) taxpayer education.

The form is prepared and certified jointly by the Clinic Director and the Qualified Business Administrator (QBA) or organizational finance director. Individual taxpayers receiving assistance from a clinic never complete or file this form.

4. Who Is Exempt / Not Required to File

Because Form 13424-L is exclusively an expenditure verification document for active federal award recipients, most organizations and individuals are completely exempt from filing it:

Individual Taxpayers: Low-income clients represented by a clinic do not file this form; their services are funded by the grant without any personal filing requirement.
Commercial Tax Practitioners: For-profit accounting firms, private law offices, and commercial tax preparers are ineligible for LITC grants and do not use this form.
New Grant Applicants: Organizations that are applying for an LITC grant for the first time submit Form 13424-J to project their proposed budget; Form 13424-L is filed only after a grant is awarded and funds are expended.
Volunteer Tax Preparation Sites (VITA/TCE): Volunteer clinics operating under the IRS SPEC division focus on tax return preparation and report expenditures through separate volunteer grant systems.
Unfunded Legal Programs: Bar associations and charitable groups providing pro bono tax representation without federal LITC grant awards do not submit Form 13424-L.

5. When to File

Form 13424-L operates on a semi-annual schedule aligned with the calendar grant year, which runs from January 1 through December 31:

Interim Report: Covers actual expenditures incurred during the first half of the grant year from January 1 through June 30. This report is typically due to the LITC Program Office by July 30.
Year-End Report: Covers cumulative expenditures for the entire grant year from January 1 through December 31. This comprehensive final accounting report is generally due by March 30 following the close of the grant year.

Specific filing deadlines are published annually in IRS Publication 3319. If an unexpected accounting emergency arises, clinics must request an administrative extension in advance from their assigned LITC Advocacy Analyst.

6. Where and How to File

Form 13424-L cannot be filed through commercial tax preparation software. It must be submitted through authorized federal grant administration portals.

Grant recipients must submit Form 13424-L electronically through the designated online LITC Grants Portal (or GrantSolutions, as directed in annual program guidelines) as part of their comprehensive Interim or Year-End reporting package. The completed form is typically uploaded as a spreadsheet alongside detailed written narrative explanations justifying cost variances.

If requested during an on-site operational review or financial sampling, clinics must provide supporting general ledger records, invoices, and time logs. If directed to send physical audit records by mail, deliver materials to the specific IRS address as per instructions outlined in IRS Publication 3319.

7. Step-by-Step Instructions to Fill the Form

Form 13424-L parallels the budget categories found on your approved Form 13424-J. For each category, you must report the approved budget, actual federal funds spent, actual non-federal matching funds contributed, and the remaining unexpended balance.

Cost Category	Expenditure Scope	Accounting Instructions
Personnel	Salaries and wages paid to clinic attorneys, directors, accountants, paralegals, and support staff.	Report payroll outlays based on actual time-and-effort logs dedicated strictly to LITC activities.
Fringe Benefits	Employer-paid FICA, Medicare, medical insurance, retirement contributions, and workers’ compensation.	Calculate fringe benefits strictly in proportion to the salary amounts charged to the LITC program.
Travel	Mileage, transit, lodging, and per diem for client hearings, community outreach, and the annual LITC Conference.	Record actual travel reimbursements paid; expenses must conform to federal per diem rate limits.
Equipment	Tangible property with a useful life over one year and a cost exceeding the capitalization threshold ($5,000).	Itemize high-value capital assets purchased with prior approval from the LITC Program Office.
Supplies	Office supplies, printing paper, toner, postage, client files, and technology items under $5,000.	Report actual invoices paid for consumable office materials and taxpayer educational brochures.
Contractual	Third-party vendor fees, certified foreign language interpreters, specialized IT support, and independent audit fees.	Detail payments made to outside contractors; attach written contracts and invoices upon request.
Other Direct Costs	Office rent, phone/internet services, malpractice insurance, bar dues, and legal research software (e.g., Westlaw).	Allocate facility costs based on verified square-footage formulas or staff allocation methodologies.
Indirect Costs	General institutional overhead and central administrative support.	Apply an approved federally negotiated rate (NICRA) or the standard 10% de minimis rate to allowable direct costs.

Reconciling Matching Funds and Writing Narratives

When compiling your expenditures on Form 13424-L, keep these core accounting principles in mind:

Meeting the 1:1 Match: Total matching fund outlays (combining non-federal cash and in-kind volunteer contributions) must equal or exceed total federal funds drawn. If federal outlays exceed matching contributions at year-end, the clinic will be required to return funds to the government.
In-Kind Volunteer Valuations: Third-party in-kind pro bono attorney or accountant hours reported in the matching column must be substantiated by contemporaneous time logs maintained on Form 13424-F.
Narrative Explanations for Variances: Form 13424-L requires a written narrative explaining any significant variance (typically 10% or more) between your approved budget on Form 13424-J and your actual expenditures. Explain why certain categories were overspent or underspent.

8. Required Documents/Information Needed Before Filling

To ensure that Form 13424-L reconciles with federal accounting databases, assemble the following source records prior to completing the form:

General Ledger Detail Reports: Accounting software reports showing every revenue and expense transaction charged to the LITC program during the period.
Approved Form 13424-J Budget: Your official approved budget worksheet and any approved budget amendments for the grant year.
Payment Management System (PMS) Drawdown Records: Official federal payment records verifying the exact dollar amount of federal grant funds drawn down by your organization.
Standard Form 425 (SF-425): The companion Federal Financial Report that must match the federal expenditures reported on Form 13424-L.
Form 13424-F Time Sheets: Verified, contemporaneous pro bono volunteer time logs supporting all claimed in-kind matching contributions.
Payroll and Invoice Workpapers: Payroll registers, quarterly payroll tax returns, paid vendor invoices, and travel expense receipts.

9. Common Mistakes to Avoid

Accounting errors on Form 13424-L can delay grant disbursements and trigger administrative audits. Avoid these frequent mistakes:

PMS and SF-425 Discrepancies: The federal expenditures reported on Form 13424-L must match your federal cash drawdowns in the Payment Management System and your entries on Standard Form 425 down to the penny.
Failing to Meet the 1:1 Match Ratio: If your non-federal matching expenditures do not equal or exceed your federal grant expenditures at the close of the grant year, the shortfall must be refunded to the IRS.
Counting Indirect Costs as Match: Under federal grant rules, general organizational indirect costs cannot be used to satisfy your non-federal matching requirement unless specifically authorized.
Omitting Variance Explanations: Shifting funds between categories without explaining the operational reasons in the narrative will cause your report to be returned for revision.
Including Unallowable Expenses: Charging prohibited costs—such as fundraising, lobbying, entertainment, alcoholic beverages, or student clinic hours for students receiving academic credit—will result in cost disallowances.

10. Penalties for Non-Filing or Errors

Because Form 13424-L is a grant expenditure report rather than an individual tax return, there are no civil tax penalties or personal fines for failing to file it. However, the federal grant consequences for the sponsoring organization are significant:

Payment Management System Freezes: The LITC Program Office will freeze your federal grant account in PMS, preventing any further cash drawdowns until delinquent reports are submitted and approved.
Grant Recoupment (Clawback): If unallowable expenses are discovered or matching fund commitments are not met, the IRS will issue a formal demand letter requiring the organization to refund money to the U.S. Treasury.
Administrative Probation: Persistent accounting errors or reporting delinquencies will result in the clinic being placed on a formal Corrective Action Plan.
Termination of Multi-Year Awards: Significant financial mismanagement will lead to the premature termination of multi-year grant agreements and disqualify the clinic from future federal awards.
False Claims Act Sanctions: Intentionally inflating reported expenditures, submitting fabricated invoices, or forging volunteer time sheets violates 18 U.S.C. Section 1001 and federal anti-fraud statutes, exposing individuals and organizations to criminal prosecution and treble damages.

12. Frequently Asked Questions

What is the difference between Form 13424-J and Form 13424-L?

Form 13424-J is a prospective budget worksheet where you project your planned expenses before or during the application process. Form 13424-L is an expenditure report where you record actual dollars spent after program activities have occurred.

Can unspent federal grant funds be rolled over to the next grant year?

No. LITC grant funds operate on a strict annual appropriation cycle. Unspent federal funds cannot be carried over into the following calendar year; any unexpended federal grant balance remaining at the end of the grant period is de-obligated and returned to the federal government.

How does Form 13424-L connect with Standard Form 425 (SF-425)?

Standard Form 425 is the government-wide Federal Financial Report, while Form 13424-L is the program-specific cost breakdown. Total federal grant outlays and total matching funds reported on Form 13424-L must match the figures entered on lines 10e and 10j of Standard Form 425 exactly.

What happens if our clinic spends less matching funds than federal funds?

If your non-federal matching expenditures do not equal or exceed your federal grant expenditures on the Year-End report, you have violated the 1:1 statutory match rule. The IRS will reduce your allowable federal grant to match your actual contributions and require you to refund the difference.

Can volunteer time be counted as matching funds on Form 13424-L?

Yes. The fair market value of donated professional services from pro bono attorneys, CPAs, and community volunteers can be claimed as in-kind matching funds, provided the hours are supported by contemporaneous time logs maintained on Form 13424-F.

Must every cost category variance have a written explanation?

You must provide written narrative explanations whenever spending in a particular category deviates by 10% or more from your approved budget. Explaining the operational reasons for budget shifts helps your analyst approve the report without unnecessary delays.

13. Conclusion: Key Takeaways Summarized

IRS Form 13424-L is the primary financial report verifying that Low Income Taxpayer Clinics spend grant dollars in accordance with federal law. Keep these fundamental practices in mind:
