Employee Benefit Plan Audits

Northern VA CPA firm specializing in employee benefit plan audits

Benefit plans are subject to unique regulatory and fiduciary requirements. Our firm provides comprehensive audits of 401(k), pension, and other employee benefit plans to protect participants, sponsors and your organization.

Audit

Northern VA CPA firm specializing in tax services

A financial statement audit provides the highest level of assurance that an organization’s financial statements are presented fairly, in all material respects, in accordance with the applicable financial reporting framework. Through a risk-based examination of financial records, internal controls, and supporting evidence, we deliver an independent opinion that enhances credibility with lenders, investors, sureties, and other stakeholders.

Review

Business Advisory

A financial statement review provides limited assurance through analytical procedures and inquiries of management, offering a cost-effective alternative to an audit. While less extensive than an audit, a review helps provide confidence that no material modifications are necessary for the financial statements to conform with the applicable financial reporting framework.

Compilation

CPA Business Advisory

A financial statement compilation assists management in presenting financial information in the form of financial statements without providing assurance on the accuracy or completeness of the information. Compilations are often appropriate for internal reporting or when financial statements are needed for certain business purposes but assurance is not required.
