It depends on the funder and program. Some grants explicitly request a nonsupplanting certification; others infer compliance through budget narratives. When in doubt, follow the funder’s application instructions or program guidance.

Most funders do not require notarization for nonsupplanting letters. If a funder or state law requires additional authentication, follow that requirement; state rules vary on notarization and witness counts.

What if factual details change?

If material facts change after submission, notify the funder and provide an amended letter signed by an authorized official to avoid audit findings.

How do I fix errors in a signed letter?

Issue a corrected letter signed by the authorized official and clearly label it as a revision. Preserve the original and the corrected version in your records for audit traceability.

What a Business Letter of Nonsupplanting Is

A Business Letter of Nonsupplanting is a signed certification from an applicant or contractor affirming that funds requested, awarded, or billed will not replace (supplant) existing federal, state, or local funding for the same purpose. Typically submitted with grant applications, contracts, or reimbursement requests, the letter documents the funding source, the period covered, and the factual basis showing the new funds augment rather than replace current support. Agencies and funders rely on this certification to enforce funding rules and to prevent improper reallocation of budgeted public resources.

Why the Business Letter of Nonsupplanting Matters

This letter protects both the applicant and the funder by confirming compliance with grant rules that prohibit using new funds to replace current funding. It preserves eligibility for awards, clarifies budgeting intent, and documents the factual basis for additional funding.

Who Typically Prepares and Receives This Letter

Use the letter any time a funder explicitly requires nonsupplanting assurance or when a budget line risks overlapping with existing funding.

Grant applicants and nonprofit finance staff responsible for federal or state grant compliance.
Contractors and vendors submitting reimbursement requests tied to public funding.
Government program officers, grant administrators, or auditors who review funding determinations.

Who Signs and Certifies

Authorized Official

An officer with legal authority to bind the organization (executive director, CFO, president). This signer certifies the accuracy of funding statements and accepts legal responsibility for compliance and potential audit findings.

Grant Manager

The program or grant manager who prepared the budget may co-sign or be listed as the contact. Their role is to attest to the programmatic facts supporting nonsupplanting and to provide documentation if requested.

Essential Elements to Include in the Letter

A complete Business Letter of Nonsupplanting is concise but precise; include identity, funding facts, a clear nonsupplanting statement, and an authorized signature.

Letterhead

Use official organizational letterhead showing name, address, phone, and email so the funder can verify origin and contact the organization directly.

Funding Identification

Specify the grant or contract name, program code, and the funding source (federal, state, or private) that the letter concerns.

Period Covered

State the dates or award period during which the nonsupplanting assurance applies to clarify timing relative to existing funding.

Nonsupplanting Statement

A clear declarative sentence stating the new funds will not replace existing funds and describing how the funds will be used in addition to current resources.

Factual Basis

Provide a short explanation—budget lines, previously funded activities, or staffing patterns—that supports why funds augment rather than supplant.

Signature Block

Include the printed name, title, signature, and date of an authorized official; include contact information for follow-up questions.

Common Mistakes to Avoid

Vague declarations that do not explain why funds are additive rather than replacement—provide concrete budget examples.
Using informal or unsigned drafts instead of a signed document on official letterhead, which weakens verifiability.
Failing to match organization names or grant numbers exactly, which delays processing and may trigger verification requests.
Submitting the letter after the funder’s deadline or after funds were already reallocated, risking ineligibility or audit findings.

Consequences of Incorrect or Missing Certification

Funding denial: Loss of award eligibility by funder.

Repayment liability: Possible requirement to return improperly used funds.

Audit findings: Negative audit results and corrective actions.

Penalties: Funder-specific fines or sanctions may apply.

Reputational risk: Damage to future funding prospects.

Legal exposure: Breach of contract claims in extreme cases.
