To fill out and submit the HHS grant application on Form SF-424, register your organization in SAM.gov and Grants.gov, open a Workspace for the specific funding opportunity, complete the SF-424 along with the budget and assurance forms the Notice of Funding Opportunity requires, and have an Authorized Organization Representative sign and submit the package through Grants.gov before the deadline. The SF-424, “Application for Federal Assistance,” is the lead form for nearly every HHS grant, and the details on it must match your SAM.gov record and your detailed budget exactly.
Read the Notice of Funding Opportunity First
Every HHS grant is governed by a Notice of Funding Opportunity (NOFO) posted on Grants.gov. Before you open a single form, read it in full. The NOFO tells you the type of award, the maximum and minimum award amounts, the deadline, eligible applicant types, any cost-sharing requirement, the scoring criteria, and every form and attachment your application must contain. It also gives you the Assistance Listing Number (formerly the CFDA number) you’ll need on the SF-424 itself.
Skipping sections of the NOFO is the fastest way to waste weeks on an application that gets screened out administratively before a reviewer ever sees it.
Register Your Organization Before You Do Anything Else
Two registrations must be active before Grants.gov will let you submit. Both are free, and both take time.
SAM.gov and Your Unique Entity Identifier
Every organization applying for federal funding needs a Unique Entity Identifier (UEI), a 12-character code assigned through SAM.gov. The UEI replaced the old DUNS number. Getting one means completing a full entity registration, which can take up to 10 business days to become active.
SAM.gov registrations expire annually. If yours lapses, Grants.gov will block your submission at the final step, so renew early rather than assuming it will process overnight. If your original entity administrator has left and no one else has administrator access, you’ll need to submit a notarized letter through the Federal Service Desk (FSD.gov) to regain control of the account. The letter goes on organizational letterhead, is signed by the president or CEO, and includes the UEI and the new administrator’s contact information exactly as it appears on their individual SAM.gov account.
Grants.gov Profile and User Roles
Once SAM.gov is active, create an organizational profile on Grants.gov. The E-Business Point of Contact (EBiz POC) — the person listed in that role in SAM.gov — logs into Grants.gov with the same email address and authorizes roles for other users.
Three roles matter for the submission itself. A Workspace Manager can create a workspace and fill out forms but cannot submit. A Standard AOR (Authorized Organization Representative) can submit the final application and manage participants. An Expanded AOR, which the EBiz POC receives automatically, has full administrative privileges across the organization. Only a Standard or Expanded AOR can click Submit. If your grant writer is a consultant or a staff member without AOR status, they can prepare everything but must hand off to an AOR at the end.
Forms in a Typical SF-424 Package
The SF-424 is the lead form, but a complete HHS application usually includes several standardized companions. The NOFO lists exactly which apply, and the common ones are:
- SF-424A, Budget Information for Non-Construction Programs — the detailed budget for research, service delivery, training, and most other HHS work.
- SF-424C, Budget Information for Construction Programs — used only when the project involves building, renovating, or modernizing physical facilities.
- SF-424B and SF-424D, Assurances — certifications that your organization will comply with federal civil rights, environmental, and administrative requirements. B is for non-construction; D is for construction.
- SF-LLL, Disclosure of Lobbying Activities — required when the award exceeds $100,000 and non-federal funds were used to lobby in connection with the application.
Filling Out the SF-424
The SF-424 looks straightforward, but small errors cause technical rejections before your proposal reaches a reviewer.
Type of Submission and Application (Fields 1–2). For a first-time application, select “Application” and “New.” For additional time or money on an existing award, select “Continuation” or “Revision” and enter the prior federal award identifier in Field 5b. The “Changed/Corrected Application” checkbox lets you fix a previously submitted package, but only before the deadline unless the agency requests otherwise.
Applicant Information (Field 8). Enter your organization’s legal name exactly as it appears in SAM.gov, not a commonly used abbreviation or a parent company name. The Employer/Taxpayer Identification Number is the nine-digit EIN the IRS assigned to your organization. Your UEI populates from your SAM.gov record. Any mismatch between the legal name, EIN, or UEI and what SAM.gov shows will flag your application during validation.
Type of Applicant (Field 12). Pick the category that describes your organization: state government, county government, nonprofit with 501(c)(3) status, private university, tribal government, and so on. Some funding opportunities restrict eligibility to certain applicant types, so confirm you qualify before you go further.
Assistance Listing Number (Field 10). This is the five-digit program number identifying the specific grant program. The NOFO provides it. Enter it exactly; a wrong number routes your application to the wrong program.
Project Title, Dates, and Description (Fields 11, 14–17). Keep the title concise but descriptive. Enter realistic start and end dates; HHS project periods typically run one to five years. The brief description in Field 15 is a plain-language snapshot of the work, not the full narrative.
Estimated Funding (Field 18). Enter the total federal dollars requested (18a), the applicant’s contribution (18b), and any state, local, or other funding (18c–18e). These numbers must match the totals on your SF-424A or SF-424C exactly. Inconsistencies between the summary here and the detailed budget are one of the most common reasons applications get flagged during administrative review.
Executive Order 12372 Review (Field 19). Some programs require state government review before a federal award is made. The NOFO will say whether the program is subject to EO 12372. If it is, check whether your state maintains a Single Point of Contact on the OMB’s list. If your state has a SPOC, contact them early; their review takes time and you may need to submit in parallel.
Authorized Representative (Field 21). The person listed here has the legal authority to bind your organization to the terms of a federal award. That is typically an executive director, provost, or chief financial officer, not the project director or grant writer. Name, title, phone, and email must be current.
Completing the SF-424A Budget
The SF-424A is where reviewers see how you plan to spend the money, and the numbers must tie precisely to your budget justification narrative.
Section B is the heart of the form. It breaks costs into standard object class categories: personnel, fringe benefits, travel, equipment, supplies, contractual services, construction (usually zero for non-construction grants), other direct costs, and indirect charges. Each category gets its own line. If the NOFO funds multiple budget periods, complete a column for each.
Section A summarizes the total budget by grant program and Assistance Listing number. Section C shows the non-federal resources you’re committing. Section D projects quarterly cash needs for the first year. Section E estimates federal funding needed for later years. Section F captures indirect cost information and remarks.
A separate budget justification narrative explains every line item. Reviewers want to see why each cost is necessary, how you calculated the amount, and how it connects to the proposed activities. “Travel — $5,000” tells them nothing. “Two round trips to CDC Atlanta for required grantee meetings, estimated at $2,500 per trip including airfare, lodging, and per diem” tells them everything.
Indirect Costs
How you charge indirect costs — rent, utilities, administrative salaries, IT infrastructure — depends on whether your organization has a Negotiated Indirect Cost Rate Agreement (NICRA). If you have one, use the rate specified in that agreement. HHS negotiates these rates through the Program Support Center’s Cost Allocation Services division, and rate proposals go through the Indirect Cost Allocation System (ICAS) portal at portal.icas.hhs.gov.
If you’ve never had a NICRA, you can elect the de minimis rate of up to 15 percent of modified total direct costs. That rate requires no documentation to justify and can be used indefinitely until you choose to negotiate a formal rate. Once elected, it applies to all your federal awards.
Unallowable Expenses
Certain expenses are flatly unallowable on federal grants no matter how you categorize them: alcoholic beverages, entertainment, fines and penalties, fundraising costs, lobbying expenses, and goods or services for personal use. Charging any of these, even buried in an “other” category, can trigger repayment demands and jeopardize future funding. The cost principles at 2 CFR Part 200, Subpart E catalog dozens of specific categories and their allowability.
Lobbying Disclosure Over $100,000
If your application requests more than $100,000 in federal funding, your organization must certify that it has not used federal funds for lobbying. If you used non-federal funds to influence the award, such as paying a lobbyist to advocate for your application, you must file Form SF-LLL. The penalty for failing to disclose ranges from $10,000 to $100,000 per violation. Applications under $100,000 are exempt from this requirement.
Submitting Through Grants.gov
All components of your application assemble in a Grants.gov Workspace tied to the specific funding opportunity. The submission sequence runs like this:
Click “Check Application” on the Forms tab. The system validates every form for missing required fields and formatting errors. If anything fails, you get a list of specific errors to fix. Don’t skip this step. Grants.gov won’t let you submit until every error is resolved.
If the person who prepared the application doesn’t have an AOR role, they click “Complete and Notify AOR,” which emails all AORs in the organization that the package is ready. An AOR then logs in, reviews the assembled forms, and clicks “Sign and Submit.” That button is only available when the forms have passed validation, the organization’s SAM.gov registration is active, and the deadline hasn’t passed.
After submission, Grants.gov assigns a tracking number (formatted as GRANT followed by digits) and sends a confirmation email. You can also find the tracking number on the Manage Workspace page under the Details tab. The Track My Application feature lets you monitor status, and you’ll receive email notifications as the application moves through the system.
Deadlines and Late Submissions
Grants.gov locks applications at the posted deadline. NIH considers late submissions only on a case-by-case basis in limited situations, and the one pre-authorized reason is service on an NIH peer review panel near the due date. Other HHS operating divisions may have their own policies, but the safest assumption is that a late application will not be accepted. Build in a buffer of at least 48 hours before the deadline to account for system slowdowns, which are common as deadlines approach.
What Happens After You Submit
Once your application clears Grants.gov’s automated checks and transfers to the HHS awarding agency, staff run an administrative screening: eligibility, completeness, required forms and attachments. Applications that fail this screen — wrong applicant type, missing budget form, expired SAM.gov registration — are returned without review. No amount of proposal writing survives an incomplete package, which is why matching your SF-424 to the NOFO and to your SAM.gov record matters as much as the narrative itself.
