How to Start a Painting Business in Wisconsin: Lead-Safe Certification Explained

If you plan to paint older homes in Wisconsin, lead-safe certification will shape your business more than any other requirement. Wisconsin does not license painters, but it runs its own lead-safe renovation program under DHS 163 instead of the federal EPA version. Paint-disturbing work in pre-1978 homes and child-occupied facilities requires a certified Lead Company, and a certified Lead-Safe Renovator must direct each job. This guide covers the lead certifications, the business registration steps that come before them, and the contract rules you will use with clients.

What Wisconsin Requires for a Painting Business

Wisconsin does not issue a painting license, and it issues no general business license at the state or county level. Most cities do not license painters either, although a few municipalities, Lake Geneva among them, have their own business licenses. Ask your municipal clerk what applies in your city before you take your first job.

Three things determine what you need: how you organize the business, whether you sell taxable products or services, and whether your jobs fall under the lead-safe rules. Painters most often underestimate the last one. Lead certification applies to the work itself, not to how you are registered, so it applies whether you operate as a sole proprietor, an LLC or a corporation.

Materials and Documents to Gather First

Collect these items before you file anything so you are not stopped halfway through a form:

• Your legal name, home address and business address
• A registered agent with a physical Wisconsin street address and an email address, if you form an LLC or corporation
• Two or three proposed business names, each checked against DFI records
• A payment method for online fees
• Dates for the one-day Lead-Safe Renovator initial course, since every person who will direct a job needs it
• Your federal tax identification number, if you already have one
• Contract templates reviewed against the ATCP 110 home improvement contract rules
• Lead-safe work supplies, such as plastic sheeting, drop cloths, a HEPA-filtered vacuum and a disposal plan for waste. Get written quotes, since these costs vary by supplier and job size.

Step 1: Choose Your Business Structure

You can operate as a sole proprietor, form an LLC or incorporate. A sole proprietorship needs no state entity filing. An LLC costs $130 to organize through the Department of Financial Institutions (DFI) using Articles of Organization, Limited Liability Company (Form 502). A business corporation costs $100 to incorporate using Articles of Incorporation, Stock, For-Profit Corporation (Form 2). Both entity types are filed with DFI, not a Secretary of State.

Many painters choose an LLC to keep business and personal finances separate, but that is a planning decision for your attorney. For tax purposes, a multi-member LLC is treated as a partnership and a single-member LLC as a disregarded entity by default. Profits then flow through to your Wisconsin individual income tax, which uses graduated rates of 3.50% to 7.65%. Wisconsin imposes no separate LLC franchise or privilege tax. An LLC that elects corporate treatment pays the 7.9% corporate rate instead. Confirm which treatment fits your situation with a CPA.

Whatever structure you pick, the lead certifications in Steps 6 and 7 still apply. Sole proprietors must hold the Lead Company certification too.

Step 2: Check and Reserve Your Business Name

An LLC name must include 'limited liability company,' 'limited company,' or the abbreviation 'LLC' or 'LC.' Variations that differ only in capitalization or punctuation are acceptable. 'Limited' may be abbreviated 'Ltd.' and 'company' may be abbreviated 'Co.' The name must be distinguishable on DFI records from other registered entities and from any reserved or registered name. Corporation names follow their own rules, so check the DFI search for those.

Run a preliminary check in the DFI corporate records database at https://apps.dfi.wi.gov/apps/corpsearch/Search.aspx. Treat the result as provisional. A name is available only once DFI examines and files your document. If you need time to finish paperwork, you can reserve a name for 120 days for $15 using Form CORP1, available at https://dfi.wi.gov/Documents/BusinessServices/BusinessEntities/Forms/CORP1.pdf.

Step 3: File With DFI and Appoint a Registered Agent

File online through DFI Business Entity File Online at https://dfi.wi.gov/Pages/BusinessServices/BusinessEntities/FileOnline.aspx. Online filings are in most cases accepted on receipt with immediate notice. DFI's statutory limit for processing new business filings is 5 business days. Paper filings go to the Milwaukee lockbox and take longer. Optional expedited service adds $100 to the filing fee, and the document is acted upon by the close of business on the first business day after receipt. If you deliver documents to the DFI customer service counter in Madison, processing within four hours costs $250 and within one hour costs $500.

Every LLC and corporation must continuously maintain a registered agent with a registered office in Wisconsin. The registered office must match the agent's business office, and it must be a physical street location. A P.O. box, mailbox service or telephone answering service does not qualify. The agent's email address is required on the formation document and on every annual report, because DFI sends official notices to the agent. Your company cannot serve as its own registered agent. If you later change the agent or office, the statement of change costs $10 online or $25 on paper.

Step 4: Calendar Your Annual Report

An LLC or corporation files a Business Corporation or Limited Liability Company Annual Report each year after its year of organization, during the calendar quarter that contains its anniversary date. The annual report fee is $25 online. Paper filing adds a $15 surcharge, bringing it to $40 by mail. The LLC report is Form 5, and the corporation report is Form 17. The due dates for an LLC are as follows:

• Organized January 1 to March 31: due March 31
• Organized April 1 to June 30: due June 30
• Organized July 1 to September 30: due September 30
• Organized October 1 to December 31: due December 31

Put the deadline on your calendar the day your filing is accepted. Missing it creates avoidable clean-up work with the state.

Step 5: Register for State Taxes Through One Stop

The Wisconsin One Stop Business Portal at https://onestop.wi.gov registers a new business with DFI, the Department of Revenue (DOR) and the Department of Workforce Development in one pass. Use it if you want a single submission rather than separate filings.

If you sell taxable products or services, you must hold a Seller's Permit from DOR through its Business Tax Registration. The initial permit costs $20 for a two-year period, and renewal costs $10 every two years. Whether your painting work requires a permit depends on what you sell and how your invoices are structured, so confirm that with DOR at https://www.revenue.wi.gov/Pages/Businesses/New-Business-home.aspx before you send your first bid.

If you will operate under a name other than your own legal name, you can register a trade name with DFI for $15. It is optional, but it is useful when your company name differs from your personal name on contracts and bank accounts. Renewal costs $15 and may be filed in the six months before expiration.

Step 6: Obtain a Lead Company Certification

Wisconsin's lead-safe renovation rules under DHS 163 require a certified Lead Company for paint-disturbing work in pre-1978 homes and child-occupied facilities. The certification costs $125 for two years or $250 for four years. Sole proprietors must also hold it. This is the company-level credential, so it is separate from the individual certifications in Step 7.

Apply through the Wisconsin Department of Health Services (DHS). The application forms and renewal process can change, so search the DHS website for the current DHS 163 lead program pages before you submit. Make sure your business name on the certification matches the exact name you registered with DFI. A mismatch can delay your approval.

Step 7: Certify a Lead-Safe Renovator for Each Crew

Every paint-disturbing job must be directed by a certified Lead-Safe Renovator. The renovator certification costs $75 for two years or $150 for four years. Candidates must be at least 18 years old, complete a one-day initial course and then complete a four-hour refresher course every four years to keep the credential current.

You can certify yourself if you will direct jobs personally. If you plan to hire a crew, make sure at least one certified renovator is assigned to every job, including jobs you are not personally on site for. Track each renovator's expiration date on the same calendar as your annual report. An expired renovator certificate can stop a job before it starts. Confirm with DHS what job records you must keep, because the rules define what documentation is expected.

Step 8: Put Your Contracts Under the ATCP 110 Rules

Home improvement contracts in Wisconsin are subject to the rules in ATCP 110, which the Department of Agriculture, Trade and Consumer Protection (DATCP) administers. Do not assume a generic painting proposal meets those rules. Before you use any template, confirm the required contract content with DATCP and have your attorney review the final version. A simple written contract that spells out scope, materials, schedule and payment terms is the foundation, but the specific required language comes from ATCP 110, not from this guide.

Step 9: Plan Insurance and Local Requirements

Talk with an insurance agent before you take paying work. Ask what general liability and property coverage a painting contractor needs, and whether your policy covers lead-safe work practices. Then check your city's zoning and permit rules, since a few municipalities add requirements that state rules do not cover.

Common Mistakes to Avoid

• Assuming painting needs no certification. Wisconsin has no painting license, but pre-1978 and child-occupied work requires the lead certifications.
• Skipping certification as a sole proprietor. The Lead Company certification applies to sole proprietors as well.
• Letting an uncertified person direct a job. Each job needs a certified Lead-Safe Renovator in charge.
• Bidding before checking the build year. Confirm whether the home was built before 1978 before you price the job, because that determines which rules apply.
• Using a P.O. box as the registered office. The registered office must be a physical street address.
• Treating the name check as final. A DFI search is preliminary until the filing is accepted.
• Dropping the LLC name designation. An LLC name must include an allowed designation such as LLC or 'limited liability company.'
• Missing the annual report. The due date depends on your organization date, so calendar it at formation.

Expected Results

Completing these steps in order may help you bid on pre-1978 and child-occupied work with documented credentials, and that documentation can help you answer questions from property managers and homeowners about lead-safe practices. Results depend on your local market, your pricing, your reputation and the quality of your work, so treat certification as a way to qualify for more jobs rather than a guarantee of more business. Many new painters find that the first six months are slower while they build references and a portfolio.
