Common Questions from Wisconsin Plan Sponsors
Are there unique 401(k) audit requirements for Wisconsin employers?
The requirements are federal under ERISA, but Wisconsin employers often manage multi-location operations or unionized plans that require specialized coordination — which our audit team handles expertly.
When is the audit and Form 5500 deadline?
The standard filing deadline is seven months after your plan year-end, with a possible 2.5-month extension. We help Alabama employers stay on track with all required documentation.
