How to Start a Tree Service Business in Minnesota: The MDA Tree Care Registry and Pesticide Rules

If you want to start a tree service business in Minnesota, the first state requirement you hit is probably not the one you expect. Minnesota has no general statewide business license. Filing your company with the Secretary of State is a filing, not a license. The rule that stops tree crews before they start is the Minnesota Department of Agriculture (MDA) Tree Care Registry. Every person or company that trims or removes trees, limbs, branches, brush or shrubs for hire must register before working (Minn. Stat. 18G.07). Advertising tree care without registering is unlawful.

This guide covers the steps in the order most owners should take them: choose a structure, file the paperwork, register with the MDA, handle pesticide rules, check city and county requirements, and set up insurance. This is informational content, not legal or tax advice. For questions about liability, employees or tax structure, talk with a qualified attorney or CPA.

What You Need Before You Start

Gather these items before you file anything. Most cost little, but a missing one can stall a filing or a first job.

• A Minnesota street address for your registered office. A PO box alone is not accepted.
• A business name you have checked in the Secretary of State business search.
• A list of the Minnesota counties where you plan to work. The MDA registry asks for this.
• A list of branch locations, if you will have more than one yard or office.
• A payment method for state fees.
• Proof of the insurance you plan to carry, or quotes from an insurance agent.
• An equipment list: chainsaws, chippers, stump grinders, and any bucket truck or aerial lift access. If you plan to spray, add spray equipment, which brings in the pesticide rules covered in Step 6.

Step 1: Choose Your Business Structure

Most tree companies start with one of two structures.

Sole proprietor under your own name. If you work under your own legal name, you generally do not file with the Secretary of State. A different trade name, such as Northern Pine Tree Care, is an assumed name and requires a certificate of assumed name (see Step 2).

Limited liability company (LLC). An LLC can separate most business debts from your personal assets. It does not shield you from your own negligence on a job, so keep insurance in place either way. Articles of Organization cost $155 filed online or in person, or $135 by mail. Minnesota has no separate LLC franchise tax. A single member LLC that reports only on the owner's individual return passes income through, and the owner pays individual income tax at rates from 5.35 to 9.85 percent. An LLC that files federally as a C corporation pays the 9.8 percent corporation franchise tax instead. A separate minimum fee under Minn. Stat. 290.0922 applies to C corporations, S corporations and partnerships, and single member LLCs reporting only on the member's individual return are exempt. Confirm which applies to you with a CPA.

Step 2: Check Your Name and Decide on an Assumed Name

Search the Minnesota business records at mblsportal.sos.mn.gov/Business/Search before you commit to a name. An LLC name must contain the words limited liability company or the abbreviation LLC. It may not contain corporation, incorporated, or their abbreviations. It must be distinguishable from every domestic LLC, LLP, corporation and limited partnership on file, authorized, registered or reserved in Minnesota (Minn. Stat. 322C.0108).

If you need time to decide, you can reserve a name for 12 months for $55, renewable in 12 month periods. The reservation form is at the Secretary of State name reservation form.

If you will operate under a name different from your legal name or LLC name, file a Certificate of Assumed Name with the Secretary of State. It costs $50 online or in person, or $30 by mail. The certificate must be published for two consecutive issues in the legal notices section of a qualified legal newspaper in the county of your principal place of business. Failure to publish may render the certificate invalid. Renew it each year at no charge. LLC and corporation formation does not require publication. Only assumed names do.

Step 3: File Articles of Organization

File online through Business Filings Online, the Minnesota Business and Lien System (MBLS), or by mail. Online and in person filings cost $155 and are expedited. Mail filings cost $135 and are not expedited. The Secretary of State does not publish a guaranteed turnaround in business days, so schedule your first bids and your MDA registration around that uncertainty, not around a promised date.

Minnesota requires a registered office, not a registered agent. The registered office must be a Minnesota street address, and it does not have to match your yard or shop. A registered agent is optional for a Minnesota domestic LLC (Minn. Stat. 322C.0113).

Once the LLC exists, the Annual Renewal is due every December 31. It costs $0 if the entity is active and in good standing. If you miss the deadline, the LLC is terminated or revoked without further notice (Minn. Stat. 322C.0705). Reinstatement costs $65 by mail or $85 online or in person. Put this date on your calendar from the first day.

Step 4: Register for Taxes Before Taxable Sales

Register with the Minnesota Department of Revenue at revenue.state.mn.us to get a Minnesota Tax ID and, where needed, a sales and use tax account. Do this before you make any taxable sales. The sales tax permit application is at the Revenue new business registration page. This tax registration is not a business license.

Whether your work is subject to sales tax depends on what you sell. If you also sell taxable goods such as mulch or firewood, the state rate is 6.875 percent plus any local taxes. Confirm with Revenue which of your items and services are taxable before you write your first invoice. If you plan to hire employees, ask Revenue and the Department of Labor and Industry (DLI) which additional registrations apply.

Step 5: Register With the MDA Tree Care Registry

The registry is a registration, not a license, but it is mandatory before you work. Every company that trims or removes trees for hire must be on it, and you cannot advertise tree care until you are. A website, truck lettering, or a social media ad can create a violation before your first job.

The key facts:

• Fee: $25 plus a $5 processing surcharge.
• Term: annual. Registrations expire December 31.
• Late renewal: a penalty of 10 percent of the fee for each month late, up to 30 percent.
• Structure: one registration per company. List your branch locations on that same registration.
• Counties: you list the counties where you work, and registrants receive forest pest alerts, including emerald ash borer and spongy moth.
• How to apply: online or by mailed form through the MDA.

The MDA says the registry does not check insurance, bonding, workers' compensation or skill. A registration number tells a customer that you are registered. It does not tell them you are insured, bonded or trained. Ask any subcontractor or crew company you hire to show its own registration and its coverage. Keep your county list current as your service area grows, and confirm with the MDA how updates are made.

Step 6: Handle Pesticide Rules Separately

Trimming and removal fall under the tree care registry. Applying pesticides for hire is a separate matter. If you spray insecticides or fungicides on trees, or treat trees with products for insects or disease in exchange for payment, you need an MDA commercial applicator license. The fee is $50. Do not apply any pesticide for hire until that license is in hand.

Confirm with the MDA which of your services count as pesticide application. Some treatments and products may fall under different rules, and that line is easy to misjudge. A common mistake is assuming the registry covers spraying, or letting a crew member spray under your company name without the license.

Step 7: Check City and County Requirements

Minnesota has 87 counties, about 853 cities and about 1,780 townships. Local rules vary widely, and the state will not tell you which ones apply to your yard. Minneapolis and St. Paul license by category, and neither issues a general business license.

• Minneapolis: issues a Tree Servicing License. Check the city's current fee before you apply.
• Duluth: lists a tree service contractor license. Check the city's current fee.
• St. Paul: licenses by category, and neither St. Paul nor Minneapolis issues a general business license. Confirm whether tree work is covered by a category in your city.
• Suburbs and townships: check zoning and local tree ordinances, particularly for removals, and any permit that applies to work in the public right of way.

To search state licenses by trade and activity, use License Minnesota at mn.gov/elicense. If a job touches a state highway right of way, ask MnDOT whether a permit applies before you start.

Step 8: Set Up Insurance and Employer Basics

Insurance is where many tree businesses get into trouble, and the MDA registration will not catch a gap. Talk with an insurance agent about general liability, commercial auto, and property damage coverage. If you have employees, also ask about workers' compensation. Ask whether your customers, property managers, or municipal contracts require specific limits or a certificate of insurance before you bid on those jobs.

If you hire employees, confirm your obligations with DLI, including workers' compensation, safety requirements, and how you classify crew members. Those rules are more complex than a registration, so this is a good point to involve an attorney or CPA.

Step 9: Calendar the December 31 Deadlines

Two annual deadlines land on the same day. Your MDA Tree Care Registry registration expires December 31, and your LLC Annual Renewal is due December 31. Set reminders for early November, and check whether your city license has its own renewal date. A missed registry renewal means the late penalty applies, and a missed LLC renewal means termination or revocation without further notice.

Common Mistakes to Avoid

• Advertising before registering. Advertising tree care without registering is unlawful, so the website and the first ad come after the registration.
• Treating the MDA registration as proof of insurance or skill. The MDA says it does not check either.
• Assuming the registry covers spraying. Pesticide application for hire needs its own MDA commercial applicator license.
• Missing the December 31 dates. The registry and the LLC renewal both expire on the same day.
• Using a trade name without filing an assumed name certificate, or filing one and skipping the newspaper publication.
• Listing a PO box as the registered office. The Secretary of State requires a Minnesota street address.
• Using corporation or Inc. in an LLC name. The statute bars those words in an LLC name.
• Skipping the city check. Minneapolis, Duluth and St. Paul each have their own category rules.

What to Expect When You Finish

When these steps are complete, you should have an LLC or a documented sole proprietorship, an assumed name certificate if you use a trade name, a Tax ID and any needed sales tax account, a current MDA registration you can show customers, a pesticide license if you spray, the city licenses your work requires, and an insurance program that matches your contracts. Results such as faster approvals or more bids are not guaranteed. They depend on your local market, your pricing, and the quality of your work.
