Common Questions from Connecticut Employers

Are Connecticut businesses subject to unique 401(k) audit requirements?

All requirements are federal under ERISA, but Connecticut employers often face multi-state payroll systems or complex employee classifications that require precise auditing and data reconciliation — areas where we excel.

When are audit and Form 5500 filings due?

Generally, seven months after the plan year ends (for calendar-year plans, by July 31). Extensions are available, and we manage all filing details to keep your plan compliant.

How much does a 401(k) plan audit cost in Connecticut?

Audit fees depend on plan size, complexity, and data systems. We offer flat-fee pricing tailored to your organization, with no hidden costs.
