Let's work together

Employee Benefit Plan Audits

Most employee benefit plans with 100 eligible employees or more are required by the U.S. Department of Labor to have an annual audit. Tonneson + Co can perform employee benefit plan audits with confidence, helping your business meet compliance and also reveal actionable insights into the effectiveness of your current benefit plan.

Governmental Audits

Non-federal organizations expending federal funding of $750,000 or more must meet certain audit requirements in accordance with the Office of Management and Budget’s (OMB) Uniform Administrative Requirements, Cost Principles, and Audit Requirements for Federal Awards (Uniform Guidance.) In addition, many organizations with human and social service contracts through Commonwealth of Massachusetts departments must file a Uniform Financial Report (UFR.)

Six employees discuss at a large conference table with accounting charts, pamphlets, and information scattered on the table.

Whether your needs include a single or program-specific audit in accordance with Uniform Guidance, or audit or compliance requirements in accordance with UFR regulations, we are here to help. We understand these processes inside and out and can help lessen the stress and associated complexities of regulatory compliance.
