Best Accounting Firms in Each Practice Area

Accountants across the nation rate the top firms in their practice areas.
Survey Methodology

Vault asked accountants to rate on a scale of 1 to 10 the top accounting firms in terms of how strong they were in three practice areas: Audit & Assurance, Tax Accounting, and Forensic Accounting. Respondents were not allowed to rate their own firm and were asked to rate only those firms with which they were familiar. Vault averaged the scores for each firm and ranked them in order.
