Top 10 LLC and Business Formation Lawyers in Madison
Wisconsin's LLC filing fee is $130 online ($170 on paper) and the annual report is $25. Madison's startup ecosystem — biotech, software, university spinouts from UW–Madison — produces a steady flow of formation work for both first-time founders and serial entrepreneurs. These ten firms cover entity selection, the operating agreement, and the Wisconsin-specific compliance work that comes after the Articles of Organization land at the Department of Financial Institutions.

Tell us what you are dealing with in plain English. We will match you with two or three vetted llc / business formation firms in Madison that handle matters like yours. Free, confidential, no obligation.
The right firm depends on what you actually need. If your matter is complex, multi-jurisdiction, or attached to a larger corporate transaction, the BigLaw branches and AmLaw-recognized firms in this list (Stoel Rives, Dorsey & Whitney, Birch Horton Bittner & Cherot, Murphy Desmond, Hill Glowacki) bring depth and scale. Expect higher hourly rates and longer engagement letters, but also the bench you want when the case has real stakes.
If your matter is more contained — a single contract, a discrete IRS notice, a one-time formation — the boutique and mid-size firms on this list are usually a better fit on cost and responsiveness. You will often work directly with the partner you met at intake. The trade-off is less breadth: a boutique that does llc / business formation brilliantly may not be the right call when the matter spills into adjacent practice areas.
If budget is the binding constraint, look at the firms above with stated flat-fee structures, free initial consultations, and small-business focus. Several of the firms on this list publish flat-fee pricing for the most common llc / business formation engagements — a real advantage when you need to budget the legal spend before you start the work.
What a llc / business formation lawyer typically costs in Madison
Simple single-member LLC, flat fee: $500–$1,200 for the formation document, EIN, registered agent, and a basic operating agreement. The Wisconsin Department of Financial Institutions filing fee is $130 (online) and is a pass-through cost.
Multi-member LLC with a real operating agreement: $1,800–$4,500. The price difference is in the operating agreement — capital accounts, profit and loss allocations, transfer restrictions, deadlock and buyout mechanics. A $500 form is not an operating agreement.
S-Corporation formation with election: $1,500–$3,000. Adds the IRS Form 2553 S-election, Wisconsin S-corp election (Form 5S), payroll setup advice, and tax coordination.
C-Corporation with stock issuance, bylaws, and shareholder agreement: $4,000–$10,000. The right structure when outside investment is on the roadmap or when there will be multiple share classes from day one.
UW–Madison spinout formation (with WARF license coordination): $6,000–$25,000 depending on IP complexity, cap table structure, and investor terms. Add the WARF license fee separately.
Ongoing corporate counsel (subscription or retainer): $600–$3,000 per month for boutique firms; $5,000+ per month for mid-size and BigLaw relationships.
Red flags to watch for when picking a llc / business formation lawyer in Madison
The big legal directories list hundreds of Madison attorneys for this work. Most are competent. A few are problematic. Watch for these patterns.
Guaranteed outcomes. No ethical attorney can promise a specific result. If a firm guarantees a court win, a tax debt cut to zero, a perfect contract that "can never be challenged," or any other certain outcome, walk away.
The disappearing partner. You meet a senior name at intake, then never speak to that person again. Your file gets handed to an unsupervised junior or a paralegal. Ask in writing who will be your day-to-day attorney and what the supervision structure looks like.
Pressure to sign on the spot. Reputable firms send you the engagement letter, give you time to read it, and let you take it home. Same-day "you have to retain us today" tactics are almost always a sign of a volume mill, not a craftsperson's practice.
No verifiable track record. The firm should be able to point to peer rankings, bar specialization, published case results, or named clients. "We have helped thousands" is marketing copy. Specific case names, transaction sizes, or third-party recognitions are evidence.
Vague fee terms. "Don't worry about cost" is a red flag. Every legitimate Madison lawyer will give you a written engagement letter with the fee structure, what is included, what triggers extra charges, and what happens if you terminate the relationship.
10 questions to ask in your free consultation
Most firms on this list offer a free or low-cost initial consultation. Use it. Bring a written list of questions and write down the answers. Compare across at least two firms before you sign anything.
Who, specifically, will handle my matter day to day? Get a name and an email. Confirm that this person, not the partner you met at intake, will be your primary point of contact.
How many matters like mine have you handled in the last three years? You want a real number, not a brochure line.
What is your fee and what does it cover? Get the answer in writing before you sign. Hourly, flat, contingency, or hybrid — and what triggers a change.
What costs am I responsible for outside the legal fee? Filing fees, expert witnesses, third-party services, courier, transcription. Ask now to avoid surprise invoices.
What is a realistic range of outcomes for a situation like mine? A good lawyer will give you a range with assumptions. A bad one will only describe the best case.
How long will it take? Honest estimate with the assumptions stated. A simple business contract is days. A multi-year IRS audit is years.
Who else might be involved? Co-counsel? Experts? Local counsel? Larger matters routinely involve outside specialists. Know who is on the team and how they bill.
How and how often will I hear from you? Email-only? Weekly calls? Status updates on a schedule? Set the expectation up front.
What happens if I want to change lawyers later? The rules allow it; the fee is sorted between firms. Make sure you understand the mechanics before you commit.
What is the worst case for me here? A lawyer who refuses to discuss downside risk is selling, not advising.
What is specific about a llc / business formation matter in Madison
Wisconsin's filing fee is modest. The Wisconsin Department of Financial Institutions charges $130 for online filing of Articles of Organization ($170 paper), plus $25 for the annual report. This is meaningfully cheaper than Illinois ($150 + $75 annual) or California ($70 + $800 annual franchise tax).
Wisconsin Revised LLC Act took effect January 2023. The new act follows the Revised Uniform Limited Liability Company Act and changes default rules around member voting, fiduciary duties, indemnification, and dissociation. LLCs formed before 2023 can opt in or remain under the prior Chapter 183. Your formation attorney should walk through whether to opt in.
UW–Madison spinout context. University of Wisconsin researchers spinning out companies need to coordinate with WARF (Wisconsin Alumni Research Foundation) on IP licensing and equity. The right Madison formation firm knows the WARF process — getting the IP license and the cap table right at formation saves months later.
Dane County and Madison business licenses. The City of Madison requires certain business licenses (food, alcohol, lodging, contractor) on top of the state-level entity formation. Dane County has additional requirements for some industries. Your formation lawyer should run the licensing checklist before you take your first dollar.
Wisconsin franchise vs. corporate income tax. Wisconsin's franchise tax applies to corporations doing business in the state at 7.9 percent. LLCs taxed as partnerships are pass-through. The entity choice has real Wisconsin tax consequences that the Articles do not capture.
Frequently asked questions
How much does it cost to form an LLC in Wisconsin?
The Wisconsin Department of Financial Institutions filing fee is $130 online ($170 paper) for Articles of Organization, plus a $25 annual report. With an attorney handling the operating agreement and post-formation compliance, all-in cost for a simple single-member LLC is typically $650–$1,500.
Does Wisconsin require a registered agent for my LLC?
Yes. Every Wisconsin LLC must maintain a registered agent with a Wisconsin street address. The agent can be a member, manager, attorney, or commercial registered agent service. Missing the registered agent is the most common cause of an LLC being administratively dissolved.
What changed under the Wisconsin Revised LLC Act in 2023?
The new act (Chapter 183) follows the Revised Uniform LLC Act. Changes include default rules on member voting, fiduciary duties, indemnification, dissociation, and oppression remedies. Existing LLCs can opt in or remain under prior rules. Most Madison formation attorneys recommend updating operating agreements to align with the new defaults.
LLC or S-Corp — which is better for a small Madison business?
An LLC is the more flexible default. An S-Corp election (you can make it on top of an LLC) usually starts to pay off in self-employment tax savings when net business income clears roughly $40,000–$60,000 per year. Wisconsin has both federal and state income tax, so the S-election analysis has Wisconsin consequences too.
How long does it take to form an LLC in Madison?
Standard online filing with the Wisconsin DFI is processed within 1–5 business days. Paper filings take 5–10 business days. A full attorney-prepared formation with a real operating agreement is usually a 1–3 week project depending on complexity.
Do I need to coordinate with WARF if I am spinning out from UW–Madison?
Almost always yes if any university-developed IP is involved. The Wisconsin Alumni Research Foundation manages UW IP licensing. The license terms, royalty rate, and equity participation all need to be coordinated with formation. Skip this step and the cap table becomes much harder to fix later.
What if I already formed an LLC online and want a lawyer to clean it up?
Common — and fixable. The firms above will review the filing, draft a real operating agreement, set up the post-formation compliance (EIN, Wisconsin tax registration, banking, payroll), and bring the entity into shape. Expect $600–$2,000 for a typical cleanup.
Will my Madison LLC protect me personally if I get sued?
Only if you respect the entity. Run the LLC as a separate business: separate bank account, signed operating agreement, no commingling, proper books, an EIN, and proper signing (your name followed by your title and the LLC name). 'Piercing the corporate veil' is what plaintiffs argue when the entity has been ignored.
One last thing. Choosing a lawyer is personal. Read the reviews. Call two or three firms before you sign. Ask each one the same opening question: How many matters like mine have you handled in the last three years, and what were the outcomes? The way they answer tells you almost everything. — The LawFirmSquare team
