How Long Should You Keep Business Records? A Wisconsin and Illinois Guide

September 8, 2026

A good records retention policy isn’t about keeping everything. It’s about keeping records for as long as they’re needed and securely destroying them when they’re not.

Regularly clearing out unnecessary materials reduces clutter and makes records easier to manage.

 

What Are You Keeping That You Don’t Need?

Are you storing information because you need it, or simply because nobody has decided to get rid of it?

Businesses often accumulate materials they may no longer need, including:

  • Duplicate copies when the official record is securely stored elsewhere
  • Outdated drafts after the final version is complete
  • Extra paper copies of records securely stored electronically
  • Superseded forms, manuals, and reference materials that are no longer in use

Regularly clearing out unnecessary materials reduces clutter and the amount of sensitive information your organization has to protect.

 

Business Records Retention in Wisconsin and Illinois

There isn’t one retention period that applies to every business record. Even the familiar seven-year rule is generally a conservative business practice rather than a universal requirement. Retention periods depend on the type of record and the requirements that apply to your organization.

Wisconsin and Illinois have different requirements for some records. Use the appropriate guide below as a quick reference for common business records.

Some Records Don’t Have a Simple Expiration Date

Reaching the date on a retention schedule doesn’t automatically mean a record is ready to be destroyed.

Some records need to be kept longer because of what is happening with the business or the record itself:

  • Contracts and leases: Keep them through the agreement. After it ends, retention may depend on how long a claim related to the agreement could still be made.
  • Property records: Keep records needed to establish tax basis for as long as you own the property. After a sale or disposal, follow the additional retention period shown in the appropriate state guide above.
  • Legal holds: If a legal hold applies, keep the affected records until the hold is formally released. Then check whether the record’s normal retention requirement still applies.
  • Tax audits and government inquiries: If a record is relevant to an active audit or inquiry, keep it until the matter is resolved. Then check whether another retention period remains.
  • Claims and disputes: If a record relates to an insurance claim, contract dispute, wage claim or employment charge, keep it until the matter is resolved and any applicable additional period has passed.
  • Pending or anticipated litigation: Preserve relevant records even if their normal retention date has passed.
  • Grants: Follow the grant’s specific requirements. Audits, award terms and other conditions can extend the normal retention period.
