Foreign registration · Form 21

Idaho Corporation Foreign Registration in Wisconsin

Wisconsin registers a corporation from Idaho as a foreign corporation on Form 21, with $100 in state fees. Wisconsin also wants Idaho's Certificate of Existence ($10), dated within 60 days. We file it with the Department of Financial Institutions, Division of Corporate and Consumer Services from your Idaho records, then serve as your registered agent there for year one.

How Idaho companies register with Wisconsin

Order the Idaho certificate
The Certificate of Existence ($10) is ordered from Idaho separately; it is not part of our Wisconsin order. Wisconsin accepts it within 60 days of Idaho's issue date, so it is ordered shortly before filing.
We prepare and file Form 21
It lists us as your Wisconsin registered agent, next to your Idaho name and formation date, with the certificate attached. The Idaho certificate comes first; then the Wisconsin filing goes in. Once Wisconsin approves it, the Idaho company can do business there.

First-year cost, Idaho to Wisconsin

Item	Amount
State fees, paid at order	$100
Certificate of Existence, paid to Idaho	$10
Our service, with a year of Wisconsin registered agent service	$199
First-year total, Idaho certificate included	$309

Wisconsin's paid expedite is optional and not in the total.

Your Idaho name and Wisconsin's rules

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 corporation files Idaho's Annual Report (no fee) and Wisconsin's Foreign Business Corporation Annual Report ($65). With our $149 registered agent renewal, Idaho plus Wisconsin comes to $214 a year. The new registration does not replace any home-state filing.

LLC or corporation, Idaho to Wisconsin

An LLC formed in Idaho files Form 521 with Wisconsin ($100 in state fees, the same; no home-state certificate is needed). After that come Idaho's Annual Report (no fee) and Wisconsin's Annual Report (Form 5 / CORP5) ($80). See the LLC filing.

The other way: Wisconsin into Idaho

A corporation formed in Wisconsin that registers with Idaho files Idaho's registration (no form number) with $103.50 in state fees. 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 does not count a one-off deal finished within 30 days.

Is this a certificate of authority?

Yes: Wisconsin issues one to Idaho corporations once the form is approved.

How much does the Wisconsin registration cost?

$299 at checkout plus $10 to Idaho for the Certificate of Existence, $309 in all (checkout is $100 in state fees plus our $199).

Do I need Idaho's certificate of good standing?

Yes: Wisconsin wants Idaho's Certificate of Existence ($10), no more than 60 days old at filing.

What are the yearly costs for Idaho and Wisconsin?

$214 a year: our $149 registered agent renewal, nothing to Idaho and $65 to Wisconsin for the yearly reports.

What if I don't register with Wisconsin?

Wisconsin can charge an Idaho company up to $65 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 corporation instead?

Yes, but Idaho keeps the original, so you run two companies: the new one files Wisconsin's Domestic Business Corporation Annual Report ($25), and the original keeps Idaho's Annual Report.
