Foreign registration · Form 521

Idaho LLC Foreign Registration in Wisconsin

Wisconsin registers an LLC from Idaho as a foreign LLC on Form 521, with $100 in state fees. Wisconsin asks nothing of Idaho here, not even the Certificate of Existence. We file it with the Department of Financial Institutions, Division of Corporate and Consumer Services using your Idaho records and act as your registered agent there for the first year.

How Idaho companies register with Wisconsin

We prepare and file Form 521
It lists us as your Wisconsin registered agent, next to your Idaho name and formation date. No Idaho paperwork holds up the Wisconsin filing. Once Wisconsin approves it, the Idaho company can do business there.

Will your Idaho name work for Wisconsin?

We search Wisconsin's records for Idaho's name on file before anything is filed.

Agents: Wisconsin and Idaho

Idaho and Wisconsin both call it a registered agent. Your current registered agent stays for Idaho; ours takes Wisconsin's papers and notices.

Staying in good standing in Idaho and Wisconsin

Each year your LLC files Idaho's Annual Report (no fee) and Wisconsin's Annual Report (Form 5 / CORP5) ($80). With our $149 registered agent renewal, Idaho plus Wisconsin comes to $229 a year. Both states' filings stay current side by side.

LLC or corporation, Idaho to Wisconsin

A corporation formed in Idaho files Form 21 with Wisconsin ($100 in state fees, the same, plus the Certificate of Existence ($10)). After that come Idaho's Annual Report (no fee) and Wisconsin's Foreign Business Corporation Annual Report ($65). See the corporation filing.

The other way: Wisconsin into Idaho

An LLC formed in Wisconsin that registers with Idaho files Idaho's registration (no form number) with $103.50 in state fees, plus the Certificate of Status ($10) dated within 90 days. See that filing.

Questions Idaho owners ask about Wisconsin

Does my Idaho company need to register in Wisconsin?

Yes, once an Idaho business operates there; Wisconsin law lists 11 activities that do not count on their own.

How much does the Wisconsin registration cost?

$299 at checkout, with nothing to pay Idaho.

Do I need Idaho's certificate of good standing?

No, Wisconsin takes Form 521 without it.

What are the yearly costs for Idaho and Wisconsin?

$229 a year: our $149 registered agent renewal, nothing to Idaho and $80 to Wisconsin for the yearly reports.

What if I don't register with Wisconsin?

An Idaho company cannot sue in court there until it registers, and Wisconsin can add up to $97.50 for each year or part of a year.

Does Wisconsin require a registered agent?

Yes: the Idaho registered agent stays, and ours covers Wisconsin for year one.

Can I form a new Wisconsin LLC instead?

Yes, but Idaho keeps the original, so you run two companies: the new one files Wisconsin's Annual Report (Form 5 / CORP5) ($25), and the original keeps Idaho's Annual Report.

How do I withdraw from Wisconsin later?

Idaho companies leave by filing a Withdrawal of Registration of Foreign Limited Liability Company; until then, Wisconsin's report stays due alongside Idaho's filings.
