A grant in aid is money that one level of government transfers to another government or to an organization to support a public purpose, with no obligation to repay it. Federal law requires agencies to use a grant agreement whenever the main goal is supporting a public activity rather than buying goods or services for the government itself.1Office of the Law Revision Counsel. 31 USC 6304 – Using Grant Agreements Hundreds of federal programs move money this way to states, cities, tribes, universities, and nonprofits, paying for highway construction, medical research, school lunches, and much else.
The mechanics are simple on paper. A federal agency announces available funding, eligible applicants apply, the agency awards money to recipients that meet the criteria, and the recipient spends the funds on the approved purpose and reports back. There is no interest and no repayment schedule. The government is not buying something for its own use; it is paying someone else to carry out an activity that serves the public.
Grant or Cooperative Agreement
The Federal Grant and Cooperative Agreement Act of 1977 sets uniform rules for when an agency must use a grant.2govinfo. Federal Grant and Cooperative Agreement Act of 1977 Two conditions have to be met: the purpose is to support or stimulate a public activity authorized by statute, and the agency does not expect to be substantially involved in carrying out the work.1Office of the Law Revision Counsel. 31 USC 6304 – Using Grant Agreements
When the agency does plan to be heavily involved during the project, the instrument is a cooperative agreement instead.3Grants.gov. Federal Grant and Cooperative Agreement Act 1977 The money still does not have to be repaid. The difference is the level of federal involvement you should expect throughout the life of the award.
The Four Main Types
The type of grant determines how much freedom the recipient has and how the money is distributed.
Categorical Grants
Categorical grants are tied to narrow, specifically defined purposes. The authorizing legislation spells out exactly what the funds can pay for, such as building schools, training first responders, or treating a particular disease. This gives the federal government significant control over how the money is spent. Recipients have little room to redirect funds toward other local priorities. The vast majority of federal grant programs are categorical.
Block Grants
Block grants hand over a lump sum for a broad policy area, such as community development, public health, or social services, and let states and localities decide how to allocate the money within that area. The Community Development Block Grant and Temporary Assistance for Needy Families follow this model. States get more autonomy than they have under categorical programs.
Formula Grants
Formula grants distribute funds automatically based on criteria written into the statute, such as population, poverty rates, or crime statistics. Recipients do not compete against each other; if you meet the eligibility requirements, you receive funding calculated by the formula. The dollar amount depends on the data inputs and the annual appropriation from Congress.4Office of Justice Programs. Grants 101 – Types of Funding Medicaid is one example: the federal government matches each state’s spending at a rate tied to per capita income, with the federal share ranging from 50 percent to 83 percent depending on the state.
Project Grants
Project grants are competitive. Applicants submit proposals, and a federal agency scores them on the strength of the plan, the qualifications of the team, and the likelihood of results. Eligibility does not guarantee funding. Most research awards from agencies like the National Institutes of Health and the National Science Foundation work this way.
Conditions on the Money
Grant funds do not have to be repaid, but they arrive with real strings.
Matching Requirements
Many grants require recipients to put up some of their own money. A common structure has the federal government covering 80 percent of a project’s cost and the recipient covering 20 percent. Depending on the program, the match can come from cash or from in-kind contributions such as donated equipment, volunteer hours, or office space.5eCFR. 2 CFR 200.306 – Cost Sharing or Matching To count, a contribution has to be verifiable in the recipient’s records, necessary for the project, and not already pledged to another federal award.
Maintenance of Effort
Some grants require you to keep your own spending at or above a historical baseline. This is called maintenance of effort, and it exists to keep federal money from simply replacing what the recipient was already spending. If a state was spending $50 million annually on a program before the grant, it typically has to keep spending at least that amount to remain eligible.6Institute of Museum and Library Services. Statutory Matching and Maintenance of Effort Requirements Falling short can trigger a proportional reduction in the federal allotment.
Allowable Costs
The Uniform Guidance at 2 CFR Part 200 is the federal government’s master rulebook for grant spending. Every cost charged to a grant has to be necessary, reasonable, properly documented, and consistent with how you treat similar costs elsewhere in your organization.7eCFR. 2 CFR 200.403 – Factors Affecting Allowability of Costs Some categories are flatly unallowable, including alcoholic beverages, entertainment, lobbying, fundraising, fines and penalties, and goods for personal use.8eCFR. 2 CFR Part 200 Subpart E – Cost Principles Charging an unallowable cost to a grant means paying it back out of your own budget.
How to Apply
Organizations that miss deadlines usually miss them because they underestimated how long the setup takes. Start with registration.
Register First
Before applying for any federal grant, your organization needs a Unique Entity Identifier and an active registration on SAM.gov, the System for Award Management. A UEI alone is not enough; you have to complete the full entity registration to be eligible to receive federal awards directly.9SAM.gov. Get Started with Registration and the Unique Entity ID Initial registration can take several weeks, and it must be renewed every 365 days. Organizations that let their registration lapse cannot receive payments on existing awards or qualify for new ones.
Find Opportunities
Federal agencies publish available funding as Notices of Funding Opportunity on Grants.gov and in the Federal Register. Each notice describes the program’s goals, eligibility, available funding, deadline, and evaluation criteria. Read the eligibility section carefully before investing time in an application. Some programs are restricted to specific types of organizations, geographic areas, or populations served.
Submit Your Application
Applications go through Grants.gov, which provides a workspace where a team can collaborate on the proposal. Strong applications address every criterion in the Notice of Funding Opportunity and back up their plans with data. For competitive project grants, the gap between funded and unfunded applications often comes down to specificity: vague promises to “improve outcomes” lose to concrete plans with measurable goals, realistic timelines, and clear budgets.
Reporting, Audits, and Enforcement
Federal agencies don’t hand over money and walk away. The Uniform Guidance creates a layered system of reporting, monitoring, and auditing that follows funds from award to closeout.10eCFR. 2 CFR Part 200 – Uniform Administrative Requirements, Cost Principles, and Audit Requirements for Federal Awards Recipients submit financial and performance reports on a schedule set by the award, usually quarterly or annually. The federal agency, or a pass-through entity such as a state agency that distributes funds to local organizations, can also conduct site visits and desk reviews at any point during the award.
Organizations that spend $1 million or more in federal awards during a fiscal year must undergo a single audit. That is an independent examination covering both the entity’s financial statements and its compliance with federal requirements for each major program.11eCFR. 2 CFR Part 200 Subpart F – Audit Requirements Results are publicly available, which means your compliance record follows you to every agency you apply to next.
When an agency or pass-through entity finds noncompliance, the Uniform Guidance gives it several remedies:12eCFR. 2 CFR 200.339 – Remedies for Noncompliance
- Withholding payments until you take corrective action
- Disallowing specific costs and requiring their return
- Partial or full suspension or termination of the award
- Debarment from receiving any federal award, sometimes for years
- Refusing to make new awards or continue existing ones
Deliberate fraud is a different category. The False Claims Act imposes civil penalties for each false claim submitted to the federal government, plus damages calculated at three times the amount the government lost, and the government recovers its litigation costs from the defendant.13Office of the Law Revision Counsel. 31 USC 3729 – False Claims People who knowingly submit fraudulent reports or billing can also face criminal prosecution. Even honest bookkeeping errors can escalate into disallowed costs and clawbacks if the documentation is sloppy.
Are Grant Funds Taxable?
It depends on who receives the grant and what it pays for. The general rule under the tax code is broad: gross income includes income from all sources unless a specific provision excludes it.14Office of the Law Revision Counsel. 26 USC 61 – Gross Income Defined For most businesses and individuals, that means grant funds are taxable.
Several exceptions matter. Nonprofits with 501(c)(3) status are generally tax-exempt, so grant income does not create a tax liability for them. Scholarship and fellowship grants used to pay tuition, fees, and required supplies at a degree-granting institution are excluded from gross income; amounts spent on room and board or received as payment for services are taxable.15Internal Revenue Service. Topic No. 421 – Scholarships, Fellowship Grants, and Other Grants
Disaster relief payments from federal, state, or local governments are excluded from gross income when they cover personal, family, or living expenses caused by a qualified disaster or reimburse the cost of repairing a personal residence.16Office of the Law Revision Counsel. 26 USC 139 – Disaster Relief Payments The same exclusion applies to hazard mitigation payments made under the Stafford Act or the National Flood Insurance Act. If your award agreement does not specifically say the funds are tax-exempt, assume you will owe tax on them.
