How to Move Your LLC to Wisconsin: Conversion vs. Domestication Under the 2023 Chapter 183 Rewrite

If you formed an LLC in another state — Illinois, Minnesota, California, Delaware — and your business has since moved its center of gravity to Wisconsin, you have three practical options. You can keep the LLC registered in its original state and qualify it as a foreign LLC in Wisconsin (paying both states' annual fees forever). You can dissolve the old LLC and form a brand-new Wisconsin LLC, losing your EIN, your banking continuity, and the chain of title on your contracts. Or you can convert the LLC into a Wisconsin LLC — one continuous entity, same EIN, new home state.

Until January 1, 2023, that third option ranged from cumbersome to impossible in Wisconsin. The state's pre-2023 LLC statute handled these moves awkwardly. The 2023 rewrite of Chapter 183 — enacted as 2021 Wisconsin Act 258 — replaced that with a modern set of "fundamental transaction" procedures based on the Revised Uniform Limited Liability Company Act: merger, interest exchange, conversion, and domestication. For moving an out-of-state LLC into Wisconsin, the one you want is conversion.

This guide explains why it's a conversion (not a domestication), walks the WDFI filing, covers the home-state side, and lays out the timeline and cost.

Conversion vs. Domestication: Wisconsin's Terms Are Specific

This is the part nearly every online guide gets wrong, because most states use the word "domestication" for an interstate move. Wisconsin does not. Under the post-2023 statute, the two procedures are distinct:

So moving an Illinois LLC to Wisconsin (it stays an LLC, just changes home state) is a conversion — Form CORP1000. The Form CORP1000 itself confirms this: it asks for the converting and converted entity's governing law as "a U.S. state or a foreign country." Form CORP1500 (domestication), by contrast, limits that field to "WI or country," because Wisconsin reserves domestication for U.S.↔non-U.S. situations.

What a Conversion Actually Does

Wisconsin conversion is governed by Wis. Stat. ch. 183, Subchapter X (“Merger, Interest Exchange, Conversion, and Domestication”). The mechanics produce three important results:

• Same entity, new home state. The LLC continues without interruption. There is no new entity formed, no successor by merger, no fictional break in the chain. The state of organization changes to Wisconsin, and Chapter 183 begins governing the LLC's internal affairs.
• All property, contracts, and obligations carry over automatically. Under Wis. Stat. § 183.1045 (effect of conversion), when the conversion takes effect, all property continues to be vested in the converted company, all debts and obligations continue against it, and all pending litigation may continue in its name. Bank accounts, leases, vendor contracts, customer agreements — none of this needs to be reassigned.
• EIN survives. Because the same legal entity continues, the IRS treats the conversion as a continuation, not a new entity formation. The same EIN remains valid — a major practical benefit compared to dissolving and reforming, where a new EIN is required.

The Home-State Half of the Process

An interstate move requires authorization from both states — the state of origin and Wisconsin. Wisconsin's authorization is in Chapter 183. Whether your home state lets an LLC move its domicile out, and what it calls that procedure, depends on the home state's law. (Many states call it "domestication" or "conversion" — the label on the home-state side doesn't change what Wisconsin requires on the inbound side.)

The majority of states now authorize an LLC to move its domicile out, including all of Wisconsin's neighbors:

• Illinois — authorizes LLC conversion/domestication under its Entity Omnibus Act (805 ILCS 415, effective 2018). File the outbound paperwork with the Illinois Secretary of State.
• Minnesota — authorizes the move under Minn. Stat. ch. 322C, the Minnesota Revised Uniform Limited Liability Company Act.
• Iowa — authorizes it under Iowa's Revised Uniform Limited Liability Company Act, Iowa Code ch. 489.
• Michigan — allows LLC redomestication under the Michigan Limited Liability Company Act.
• Delaware — well-developed transfer/domestication statute, often the source state for moves out.
• California — authorizes conversion to a foreign (out-of-state) entity, which functions as the outbound side of the move.

A handful of states still don't authorize an LLC to move its domicile out. If you formed your LLC in one of those, the practical workaround is to form a new Wisconsin LLC, transfer assets, and wind up the old entity. That is a more involved process with different tax considerations — talk to counsel before committing.

Step-by-Step: Converting an Out-of-State LLC Into Wisconsin

1. 1

   Confirm both states authorize the move

   Verify that your home state permits an LLC to move its domicile out. Most do; check the home state's LLC statute or its Secretary of State's website. Wisconsin's authorization on the inbound side is automatic under Chapter 183, Subchapter X.

2. 2

   Draft a Plan of Conversion

   Under Wis. Stat. § 183.1042, the LLC must adopt a plan of conversion. The plan identifies the converting LLC, its current and proposed states of organization, the terms and conditions of the conversion, and the Wisconsin operating agreement (or amendments). It typically references the existing operating agreement and any changes needed to conform to Wisconsin law.

3. 3

   Obtain member approval

   Per Wis. Stat. § 183.1043, the plan must be approved by the members in the manner the operating agreement requires for fundamental changes — commonly unanimous consent of all members, though the operating agreement may set a lower bar. Sole-member LLCs need only the single member's written consent. Document the approval in the LLC's records.

4. 4

   File the home-state outbound paperwork

   Most home states require an articles-of-conversion or articles-of-domestication (out) filing, typically with a modest fee. The home state usually wants evidence that Wisconsin has accepted the move, so this step often runs in parallel with the Wisconsin filing rather than strictly before it. Check your home state's specific sequence requirements.

5. 5

   File Wisconsin Articles of Conversion (Form CORP1000)

   The Wisconsin filing is Form CORP1000, Articles of Conversion, under Wis. Stat. § 183.1044. It identifies the converting entity (name, type, and home state) and the converted Wisconsin LLC (name, type, "Wisconsin"), and you'll set up the Wisconsin registered office and registered agent. The form supports an optional delayed effective date (up to 90 days out) if you want the move to land on a particular date.

6. 6

   Update collateral records

   After the conversion takes effect: notify your bank (the EIN and account remain, but the banking resolution typically references Wisconsin law going forward), update vendor and customer master records to reflect the new state, update marketing materials and your website footer, and add the Wisconsin annual report deadline to your calendar (the calendar quarter that contains your Wisconsin effective date, beginning the year after).

Cost and Timeline

Wisconsin's filing fee is modest. Most of the cost comes from the home state's process and any legal drafting:

The Wisconsin Articles of Conversion are a paper filing submitted by mail with the $150 fee; standard processing takes about five business days after the WDFI receives the document, and next-business-day expedited service is available for the extra $100. The full end-to-end timeline depends on the home state's process — some home states take a week or two to issue confirmation of the outbound side. Realistic end-to-end window for a clean move is two to four weeks, with most of the time spent waiting on the home state.

Tax and Banking Implications

The key tax point: this kind of conversion is generally not a taxable event for the LLC or its members. The IRS treats the entity as continuing, so there's no deemed liquidation, no deemed asset transfer, no recognition of built-in gain. The LLC keeps its tax year, its accounting methods, and its EIN.

Where it gets fact-specific:

• State income tax. The LLC's apportionment factors may shift if the principal place of business moves. Wisconsin's apportionment rules apply to income earned within the state. Talk to your accountant about the year-of-move return.
• Sales tax registration. If the LLC will continue to make sales in the old home state, the home state's sales tax nexus likely persists. The Wisconsin Department of Revenue (DOR) registration is a separate question handled at the entity's first Wisconsin sale.
• Payroll. If the LLC has employees, the move may affect state withholding registration. Wisconsin DOR registration and unemployment-insurance registration are required for employees working in Wisconsin.
• Banking. Your existing bank should be able to keep the account open under the existing EIN. They'll typically ask for a new banking resolution citing Wisconsin law and Chapter 183, along with the WDFI-stamped Articles of Conversion. The account number doesn't change.

When Converting Isn't the Right Answer

A statutory conversion is the cleanest path in most cases, but not all:

• If your home state doesn't authorize an LLC to move its domicile out. A handful of states still don't. The workaround is to form a new Wisconsin LLC and wind up the old entity — with attention to contract assignment and customer notice.
• If you still operate substantially in the home state. If most of your revenue still comes from the old state, foreign-qualifying your Wisconsin LLC in the home state may make more sense than fully moving. Two annual filings, one entity.
• If you're a multi-member LLC and not all members agree. A conversion is a fundamental change requiring member approval. If the membership is split, that's a governance problem to resolve before the procedural step.
• If your LLC has investor preferences, convertible debt, or other capital structure built around the home state's LLC act. The change in governing law can have substantive effects on those instruments. Get counsel involved before signing the plan of conversion.

Common Mistakes

• Filing the domestication form (CORP1500) for an interstate move. In Wisconsin, an out-of-state U.S. LLC moving in is a conversion — Form CORP1000. Domestication (Form CORP1500) is reserved for U.S.↔non-U.S. transactions. Using the wrong form gets the filing rejected.
• Skipping the home-state filing. The Wisconsin filing alone doesn't remove the LLC from its home state. Without the home-state outbound filing, the LLC is double-registered — legally a Wisconsin LLC and also still registered in the home state, with two sets of annual filings due forever.
• Not updating the operating agreement. The pre-move operating agreement was drafted against the home state's LLC act. Wisconsin's act has different default rules. Either amend the operating agreement to conform to Chapter 183 or confirm that the governing-law section explicitly chooses Wisconsin.
• Forgetting the Wisconsin registered agent. Wisconsin requires a Wisconsin registered agent. The Articles of Conversion identify the agent; if you don't have one lined up, the WDFI will reject the filing. Our registered agent guide covers the requirements.
• Assuming the move resets the annual-report clock cleanly. The first Wisconsin annual report is due in the calendar year after the move, in the quarter containing the Wisconsin effective date. Check the WDFI guidance for the specific date.
