Questioned costs in a single audit are expenses charged to a federal award that the auditor suspects or determines to be unallowable, unsupported by documentation, or unreasonable. They often arise from violations of laws, regulations, or grant terms and generally must exceed $25,000 for a major program to be reported.
However, if the auditor does become aware of questioned costs for a Federal program that is not audited as a major program (for example, as part of audit follow-up or other audit procedures) and the known questioned costs are greater than $25,000, the auditor must report this as an audit finding.
Smaller nonprofits with straightforward finances can expect to pay around $5,000 to $10,000. Mid-sized organizations might see fees in the $10,000 to $25,000 range, while large nonprofits with complex funding streams, multiple programs, or international operations may face audit costs of $25,000 to $50,000 or more.
