Compliance

The first time a Wisconsin LLC owner hires a contractor, the process feels deceptively simple: agree on the work, agree on the price, send a payment. The problem is what happens after the first project. Without the right paperwork, you end up scrambling at year end for 1099 information, exposed to misclassification claims, and unable to prove the basics of the engagement if a dispute starts.

The checklist below is the order Wi Filings recommends for any Wisconsin LLC engaging an independent contractor — from before the work starts through year-end tax filings.

Step 1: Verify the worker actually qualifies as a contractor

Before you send a contract or a payment, ask the classification question. If the working relationship looks like an employee relationship (you set their hours, you supply tools, you supervise day-to-day execution, the worker depends on you economically), the contractor label and a signed contractor agreement will not change the legal classification.

Wisconsin worker classification is not one single test

Wisconsin worker classification can be reviewed under more than one legal framework. A worker who looks like an independent contractor for one purpose may still need to be analyzed under another.

Common Wisconsin frameworks include:

For worker’s compensation, Wisconsin uses a statutory nine-part test under Wis. Stat. § 102.07(8). For unemployment insurance, Wisconsin uses a separate statutory test under Wis. Stat. § 108.02(12). Do not assume that calling a worker a contractor, issuing a 1099, or signing a contractor agreement settles the classification question.

If the answer is genuinely uncertain, pause and consult a Wisconsin employment attorney, CPA, or payroll professional before the work starts. Reclassification after the fact is much more expensive than getting it right up front. For more depth on the distinction, read our companion guide on 1099 contractor vs. employee classification in Wisconsin.

Step 2: Collect Form W-9 before paying the first invoice

The W-9 is the foundation of every 1099-NEC you may need to issue at year end. It captures:

• The contractor’s legal name (or business legal name)
• Their business name or DBA, if different
• Their taxpayer ID number (SSN for individuals, EIN for businesses)
• Their entity type (sole proprietor, partnership, LLC, S-corp, C-corp)
• A signed certification under penalties of perjury

Without a W-9 on file, you do not know whether the contractor is a corporation (often exempt from 1099 reporting), an LLC taxed as a corporation (also exempt), or a sole proprietor or single-member LLC (almost always reportable). The W-9 is also your defense if the IRS later asks why you did not withhold backup withholding on a contractor without a valid taxpayer ID.

Step 3: Sign a Wisconsin-aware independent contractor agreement

A short written contract beats a Slack thread. The agreement should cover scope, payment terms, intellectual property, confidentiality, classification language, termination, insurance, indemnification, and Wisconsin governing law. Read our Wisconsin contractor agreement guide for what every clause should say.

Step 4: Set up the contractor as a vendor in your books

Create a vendor record in your accounting system before the first payment. At minimum:

• Vendor legal name and business name
• Vendor address
• Vendor taxpayer ID (from W-9)
• 1099 reporting flag, set based on the W-9 entity type
• Default payment method and terms

Most accounting platforms (QuickBooks, Xero, Wave, FreshBooks) ask for this information up front and use it to generate 1099-NEC forms at year end. Setting it up correctly the first time saves hours every January.

Step 5: Verify insurance and licensing where needed

For trades, on-site work, anything involving customer property, or anything safety-sensitive, require a certificate of insurance (COI) naming your Wisconsin LLC as an additional insured. Common coverages to require:

• General liability — for property damage and bodily injury arising from the contractor’s work
• Worker’s compensation — for the contractor’s own workers (some contractors are exempt under Wisconsin law; verify)
• Auto liability — if the contractor will drive on your business
• Professional liability (E&O) — for advice, design, or service-delivery roles where mistakes could cause client loss

If the contractor’s industry requires a Wisconsin license (electrician, plumber, HVAC, certain construction trades), verify the license is active before the work starts.

Step 6: Pay the contractor through a documented method

Use a method that creates a paper trail tied to your LLC, not your personal accounts. Best practices:

• Pay from a business checking account in your LLC’s name
• Pay against an invoice, not by handshake
• Use ACH, check, or business credit card — not personal Venmo or Zelle
• Save digital copies of every invoice, with the project or contract referenced
• Reconcile contractor payments to the bank statement monthly

Step 7: Issue Form 1099-NEC at year end if required

Do I need to issue a 1099-NEC to a contractor?

Maybe. Businesses generally issue Form 1099-NEC for certain service payments made to nonemployees in the course of business, often when payments total at least $600 for the year. But the rule has exceptions, including many payments to corporations, payments for goods, attorney-fee rules, and payments made through some third-party payment networks. Collect Form W-9 before paying contractors and check the current IRS Form 1099-NEC instructions before filing.

The W-9 you collected in Step 2 is what tells you whether a 1099 is required. Most accounting platforms generate the forms automatically, but verify each one against your records before filing.

Wisconsin-specific red flags that increase misclassification risk

• You hire several "contractors" who only work for your LLC
• You require workers to be at your location on a fixed schedule
• You supply tools, vehicles, uniforms, or software accounts
• You provide training and detailed instructions on how to perform the work
• You pay hourly with no defined project scope
• The contractor cannot subcontract or send a substitute
• You provide benefits (PTO, health, retirement) that look like employment perks
