How to Start a Landscaping Business in Wisconsin (2026)

Last updated: February 25, 2026

Starting a landscaping business in Wisconsin does not require a state landscaping license for general mowing and maintenance work. The key regulatory hurdle is pesticide certification from DATCP (Department of Agriculture, Trade and Consumer Protection) if you apply any herbicides, insecticides, or chemical lawn treatments. Wisconsin also has a phosphorus fertilizer ban on established turf and requires a Fertilizer Dealer License if you mix fertilizer ingredients. Landscaping services are taxable at 5%-5.5% (state + county surcharge), though snow plowing and removal are exempt. Workers’ compensation is required once you have 3 or more employees or pay $500+ per quarter. LLC formation costs just $130 online. This guide covers every requirement from official Wisconsin sources.

How to Start a Landscaping Business in Wisconsin (Step by Step)

Step 1: Form Your Business Entity

Register an LLC with the Wisconsin Department of Financial Institutions ($130 online, $170 by mail). Apply for a free federal EIN from the IRS. Wisconsin does not require a general business license at the state level. Check with your city or county clerk for any local business license or permit requirements.

Annual report: Wisconsin LLCs must file an annual report with DFI ($25 online). Due each year by the end of the quarter in which the LLC was formed.

Step 2: Get DATCP Pesticide Certification and Licensing

If your landscaping business applies any pesticides, herbicides, or chemical lawn treatments, you must hold certification and licensing from the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP).

Requirement	Cost	Renewal
Category 3.0 (Turf & Landscape) Certification Exam	Free (paper) or $45 (computer via Pearson VUE)	Recertify every 5 years
Individual Commercial Applicator License (ICAL)	$45/year	Annual (Jan 1 – Dec 31)
Pesticide Business License (PBL)	$80/year (+ $12.50 bulk storage surcharge)	Annual (Jan 1 – Dec 31)

Exam details: The Category 3.0 exam requires a 70% passing score. Paper-based exams are offered free at scheduled DATCP locations. Computer-based exams are available year-round through Pearson VUE for $45. Study materials are available through the UW Pesticide Applicator Training (PAT) Program.

Landscape Pesticide Registry: Wisconsin maintains a registry of addresses that request advance notice before pesticide applications. Landscaping businesses must provide 12 hours advance notice to any registered address within the treatment area.

Step 3: Obtain Additional DATCP Licenses If Needed

Fertilizer Dealer License: Required if you mix fertilizer ingredients (not needed if you simply apply pre-mixed products). Cost is $40/year plus a $0.67/ton tonnage fee. Register through DATCP.

Nursery Dealer License: Required if you buy plants, trees, or shrubs at wholesale and resell them to customers as part of your landscaping services. Fees range from $30 to $400+ per year based on annual plant purchases.

Step 4: Get Insurance Coverage

General liability insurance ($1M per occurrence recommended) is essential for any landscaping business. Typical cost: $610-$1,453/year depending on revenue and services offered.

Commercial auto insurance is required for all work vehicles and equipment transport. Average cost: approximately $1,668/year for landscaping businesses.

Workers’ compensation is required once you have 3 or more employees or pay $500 or more per quarter in wages. Coverage is through private carriers regulated by the Wisconsin Department of Workforce Development (DWD).

Landscaping Activity	Rate per $100 Payroll
Lawn maintenance (mowing, trimming)	~$2.33
General landscaping (planting, grading)	~$4.39
Tree trimming/removal	~$7.63

Vehicle/DOT requirements: You need a USDOT number if your vehicle’s gross vehicle weight rating (GVWR) exceeds 10,001 lbs. A CDL Class A license is required if your gross combination weight rating (GCWR) exceeds 26,000 lbs (truck + loaded trailer).

Step 5: Register for State Taxes

Landscaping services are taxable in Wisconsin. Mowing, planting, spraying, fertilizing, and trimming are all subject to Wisconsin’s 5% state sales tax plus any applicable 0.5% county surcharge (most counties impose this, bringing the total to 5.5%). Register for a Seller’s Permit through the Wisconsin Department of Revenue.

Snow plowing and removal are NOT taxable in Wisconsin. If you offer both landscaping and snow removal, you must separately account for taxable and non-taxable services.

Income tax: Wisconsin has progressive rates from 3.5% to 7.65%. Register for withholding if you have employees.

Step 6: Know Environmental and Fertilizer Rules

Wisconsin has specific environmental rules that directly affect landscaping businesses:

Phosphorus Fertilizer Ban

Wisconsin law prohibits applying phosphorus-containing fertilizer to established turf. Exceptions include newly seeded or sodded lawns (first growing season) and situations where a soil test confirms phosphorus deficiency. This is a statewide rule – violation can result in fines.

Frozen Ground and Impervious Surface Rules

You cannot apply fertilizer to frozen ground or impervious surfaces (driveways, sidewalks, streets). Any fertilizer that lands on impervious surfaces must be swept back onto the lawn.

Stormwater Permits (DNR)

Any landscaping project that disturbs 1 or more acres of land requires a stormwater construction permit from the Wisconsin Department of Natural Resources (DNR). Permit fees range from $140 to $350 depending on project size and type.
