Behavioral health organizations rely heavily on federal funding, and grant compliance for behavioral health programs has become one of the largest financial risks these providers face. A single disallowed cost can trigger a repayment demand, an audit finding, or a future funding restriction. Treatment centers, community mental health clinics, and substance use disorder programs that depend on SAMHSA and other federal awards must understand which costs the government will pay for and which it will claw back.
Quick answer: A cost charged to a federal behavioral health grant is allowable only if it is necessary, reasonable, allocable to the award, consistent with your organization’s normal accounting policies, and adequately documented. These criteria come from the Uniform Guidance at 2 CFR Part 200, Subpart E. Costs that fail any one of these tests, or that appear on the regulation’s list of unallowable items, become disallowed costs that must be refunded to the federal government, often with interest.
The stakes are concrete. Auditors review behavioral health awards closely, and payroll documentation problems are among the most frequently cited deficiencies. Organizations that build compliance discipline into daily operations, rather than scrambling at audit time, protect both their funding and their mission. This article explains the framework, the most common traps, and the documentation practices that hold up under federal scrutiny.
The Regulatory Framework Governing Behavioral Health Grants
Most federal behavioral health funding flows through the Substance Abuse and Mental Health Services Administration (SAMHSA), an agency within the U.S. Department of Health and Human Services. SAMHSA awards are governed by the Uniform Guidance, the set of cost principles and administrative requirements codified at 2 CFR Part 200. HHS completed its transition to that guidance on October 1, 2025, phasing out its older 45 CFR Part 75 rules and relocating its department-specific modifications to 2 CFR Part 300. Awards issued in recent grant years are subject to 2 CFR Part 200, supplemented by those HHS-specific provisions.
The cost principles live in Subpart E of Part 200. They apply to direct program costs, indirect costs, and cost-sharing or matching contributions. Whether you operate a residential treatment facility, an outpatient clinic, or a regional prevention initiative, the same rules determine what you can charge.
Compliance is not optional fine print. Section 200.410 of the Uniform Guidance states that payments made for costs determined to be unallowable “must be refunded with interest to the Federal Government.” That obligation survives the grant period, so a cost approved on a drawdown today can still be disallowed during an audit years later.
Behavioral health providers also face a layer of program-specific terms in their Notice of Award. Those terms can restrict or prohibit costs the general regulations might otherwise permit. A federal block grant, a discretionary cooperative agreement, and a state pass-through subaward can each carry distinct conditions, and the most restrictive term controls. Reading the award document alongside the regulation is the starting point for any compliance program. Organizations that want a deeper review of their funding structure can work with a firm experienced in the behavioral health industry.
It also helps to understand who enforces these rules. The awarding agency, the cognizant agency for indirect costs, any pass-through entity, and an independent single auditor can each examine the same charges from a different angle. A cost that clears one reviewer can still draw a question from another, which is why the safest posture treats every charge as if it will be tested by the strictest of them.
The Five Tests Every Cost Must Pass
The Uniform Guidance at 2 CFR 200.403 sets out the factors that determine whether a cost is allowable. Five of them drive most audit decisions, and a cost must satisfy all of them, not just some.
Necessary and reasonable. A cost is necessary if it is required to meet a program or project objective. It is reasonable if it reflects what a prudent person would pay under the circumstances. A behavioral health grant can pay for clinical staff time, but a luxury vehicle or a lavish staff retreat would fail the reasonableness test even if loosely tied to the program.
Allocable to the award. A cost is allocable when it is incurred specifically for the federal award, or it benefits both the award and other work and can be distributed in reasonable proportion. If a case manager splits time across a SAMHSA grant and a state-funded program, only the grant-related portion is allocable to the federal award.
Consistent with your accounting policies. Costs must be treated uniformly across federally financed and other activities. You cannot classify an expense as a direct cost on a grant while treating the same type of expense as an indirect cost elsewhere. Section 200.403 prohibits assigning a cost as direct if a like cost in similar circumstances is treated as indirect.
Conforming to limitations and GAAP. Costs must follow any limits in the regulation or the award, and they must be determined in accordance with generally accepted accounting principles. Certain categories carry hard caps or outright prohibitions, which the next section addresses.
Adequately documented. Costs must be supported by records that comply with the internal control and financial management standards in 2 CFR 200.300 through 200.309. Documentation is where most behavioral health grants run into trouble, and it is the test auditors examine most aggressively.
Read together, these five tests act as a single gate. A salary line can be perfectly reasonable and squarely within the budget period yet still fall out of compliance because the supporting time records do not exist. Treating the tests as a checklist applied to every material charge, before the money moves, prevents the most expensive surprises.
Common Disallowed Costs in Behavioral Health Programs
Several cost categories generate audit findings year after year. Knowing them in advance lets you build controls before money moves.
Payroll without time-and-effort support. Salaries are usually the largest line item on a behavioral health grant, and they are the most common source of disallowed costs. Charging payroll based on budget estimates rather than actual hours worked, missing supervisor approvals on timesheets, and failing to reconcile labor charges to certified after-the-fact records are recurring findings. Under 2 CFR 200.430, charges to federal awards for salaries and wages must be based on records that accurately reflect the work performed.
Advertising and public relations. These costs are generally unallowable under 2 CFR 200.421, with narrow exceptions. Recruitment of personnel for the award, procurement of goods and services for the award, and program outreach required to meet the award can qualify. General promotion of the organization, fundraising appeals, and image-building campaigns do not.
Indirect costs charged incorrectly. Applying an indirect cost rate the organization has not negotiated or elected, or charging the same expense as both direct and indirect, produces disallowances. Organizations without a negotiated rate may elect the de minimis rate of up to 15 percent of modified total direct costs permitted under the Uniform Guidance, but they must apply it consistently.
Costs outside the period of performance. Expenses incurred before the budget start date or after the end date are generally unallowable. A treatment program that pays for services in a month the award did not cover cannot charge that cost to the grant.
Other commonly unallowable items. The regulation specifically restricts or bars alcoholic beverages, fundraising and lobbying, certain entertainment costs, fines and penalties, and bad debts. Behavioral health providers should map their chart of accounts against this list so flagged categories never reach a federal drawdown. Providers preparing reimbursement filings often pair this review with formal cost report preparation to keep allowable and unallowable costs cleanly separated.
A pattern runs through these categories: the cost itself is often legitimate for the organization, but it does not belong on the federal award. Lobbying, organizational fundraising, and image advertising support the entity, yet the government will not pay for them. Separating mission-appropriate spending from grant-eligible spending in the books is the practical defense.
Documentation Practices That Survive an Audit
Documentation is the difference between a defensible cost and a disallowed one. Auditors do not assume good faith; they test whether records substantiate every charge.
Time and effort reporting is the foundation. Each employee charged to a grant should have records that reflect total activity, with the federally funded portion supported by actual time rather than projections. Supervisors should review and approve these records on a regular cycle, and the organization should reconcile charged amounts to payroll at least quarterly.
Procurement records matter as well. Purchases above your micro-purchase and simplified acquisition thresholds require documented price competition or sole-source justification. Keep quotes, purchase orders, invoices, and proof of payment together so the trail is complete.
Internal controls tie the system together. Segregation of duties, written accounting policies, and a clear cost allocation methodology demonstrate that allowability is built into operations rather than reconstructed after the fact. Organizations that maintain a current indirect cost rate agreement or a documented de minimis election remove a frequent point of dispute.
A simple test reveals whether your records will hold. Pick any charge on a recent federal drawdown and trace it back to its source: the invoice, the approval, the time record, and the policy that classifies it. If that trail takes more than a few minutes to assemble, an auditor will notice the gap, and so should you. Building the trail at the moment of the transaction costs far less than reconstructing it under deadline pressure.
Finally, watch the single audit threshold. Under 2 CFR 200.501, a non-federal entity that expends $1,000,000 or more in federal awards during its fiscal year must obtain a single or program-specific audit. That threshold rose from $750,000 for fiscal years beginning on or after October 1, 2024, so behavioral health organizations near the old limit should confirm their current obligation.
Building a Compliance Culture, Not a Compliance Event
The organizations that avoid disallowed costs treat compliance as continuous. They train program and finance staff together, reconcile grant charges monthly, and review award terms whenever a new grant arrives. They flag questionable costs before drawdown rather than defending them at audit.
A practical first step is a crosswalk: list every cost category your behavioral health programs incur, then mark each as allowable, conditionally allowable, or unallowable under the Uniform Guidance and your specific award terms. Update it when grants change. This single document prevents many of the errors auditors cite.
Roles deserve the same clarity as costs. Someone should own the award terms, someone should own time-and-effort certification, and someone should own the monthly reconciliation, with no single person controlling a charge from start to finish. That separation is not bureaucracy; it is the control that keeps an honest mistake from becoming a finding.
Behavioral health providers carry a difficult mission under tight margins, and lost grant funds hit both. Treating the five allowability tests and the documentation standards as operating rules, not paperwork, keeps federal dollars working for the people the programs serve.
Frequently Asked Questions
What makes a cost unallowable on a SAMHSA grant?
A cost is unallowable if it fails any allowability test in 2 CFR 200.403, meaning it is unnecessary, unreasonable, not allocable to the award, inconsistent with your accounting policies, or inadequately documented. It is also unallowable if it falls under a prohibited category such as lobbying, fundraising, most advertising, or alcoholic beverages, or if your specific Notice of Award restricts it.
What happens if an auditor identifies disallowed costs?
Disallowed costs typically must be refunded with interest to the federal government under 2 CFR 200.410. The finding can also affect future funding decisions and may require a corrective action plan. Strong documentation and prompt response reduce both the financial exposure and the reputational impact.
How long should we keep grant records?
The Uniform Guidance generally requires financial and program records to be retained for three years from the date the final financial report is submitted, though longer periods apply if litigation, a claim, or an audit is underway. Behavioral health providers should keep payroll, procurement, and cost allocation records together for the full retention period.
When does our organization need a single audit?
A single or program-specific audit is required when your organization expends $1,000,000 or more in total federal awards during its fiscal year, per 2 CFR 200.501. That threshold increased from $750,000 for fiscal years beginning on or after October 1, 2024, so confirm your current federal expenditure level before assuming you are exempt.
