Do You Need a License to Sell Microgreens in Illinois?

No license, and for greens you cut only to harvest and sell raw, no registration either. A cottage food registration is the route for anything past that.

The Illinois Department of Agriculture's farmers market food safety guide says it plainly. Under the Farm Products Marketing Act, 505 ILCS 70, "microgreens (only cut for harvesting, minimally rinsed to remove visible soil)" are among the foods "allowed at farmers markets with no restrictions", and they may be sold "in unsealed bags, or containers, or bagged at the time of sale". Its note on microgreens adds that greens "field harvested and bagged or ... harvested from medium on site during the farmers market are considered an agricultural product as long as it is not sold as ready to eat." Behind that sits 505 ILCS 70/1, which gives every farmer and gardener the right to sell their own produce "without paying any state, county or city tax, or license, for doing so."

So, cut your own microgreens at harvest, rinse off soil at most, put them in an unsealed bag or container, do not sell them as ready to eat, and you need no registration. The rest of this page is about what lies past that line. Sealed packages and greens sold as ready to eat fall outside the no-restrictions list, and for those Illinois wrote a route with microgreens in it by name.

Illinois puts that route somewhere almost nobody looks for a produce answer: the cottage food section of the Food Handling Regulation Enforcement Act, at 410 ILCS 625/4. That section prohibits sprouts and prohibits cut leafy greens. Then it defines a microgreen on its own terms, as an edible seedling grown in soil or a substrate and harvested above the substrate line, and it excludes microgreens from leafy greens for that section.

Read those three moves together and the carve-out is obvious. The statute bans the two categories a regulator would otherwise drop your crop into, and then writes your crop out of one of them by definition. A soil-grown or substrate-grown microgreen harvested above the line is not a sprout and is not a cut leafy green. It is a microgreen, which the section handles on its own terms.

Note what the statute is doing, because it is not an exemption. Illinois does not put your crop outside food regulation. It gives you a defined route through it, and that route has conditions attached that matter more than the paperwork does.

The route costs a registration, not a license. Section 4(c) says the local health department "shall register" an eligible operation and issue a certificate carrying an identifying registration number. It renews annually, and the local registration fee is capped at no more than $50.

Here is the part most growers get backwards. That $50 is a fee ceiling, not a sales cap. The current Section 4 states no statewide dollar limit on cottage food sales at all, checked 7 August 2026. Most states make you count your revenue. Illinois makes you count your channels instead.

Because the limit is channel-shaped, it bites hard in one specific place. Cottage food must be sold direct, for the consumer's own consumption, not for resale. A restaurant and a grocer both buy to resell. The moment you sell to either one, this route is gone and you are into a different conversation with the same local health department.

The federal layer applies on top. See the FDA Produce Safety Rule page.

Where the line falls

The issuer is the point most guides get wrong. There is no single statewide licensing desk for this. The certificate comes from the State-certified local health department for the unit of local government where the operation sits, and IDPH's retail food page exists mainly to send new food businesses to the right one and to publish the directory. When you need to escalate above the county, IDPH's Foods, Drugs and Dairies Division is on 217-785-2439.

The definition that does the work

Most states answer the microgreens question by accident. The statute was written about produce stands, or raw agricultural commodities, or home kitchens, and a grower has to reason their crop into or out of language that never contemplated it. Illinois wrote the word down.

Two limits on how far that carries you.

First, the definition does not launder a sprout. If the crop is grown in water and harvested with the seed and root, calling it a microgreen on a label does not move it between the rows above. The definition turns on soil or substrate and on harvesting above the substrate line, and those are physical facts about your bench, not marketing decisions.

Second, the definition describes a harvested product. So, if you plan to sell living trays, the carve-out may not reach them, and the living tray section below is the one to read before you take that order.

The registration, and the number that is not a sales cap

Section 4(c) is the operative machinery. An eligible operation registers with its local health department, which "shall register" it and issue a certificate bearing an identifying registration number. Registration is annual. The local registration fee may be no more than $50.

That ceiling is doing something different from the numbers you have read about in other states. A cottage food cap in most states is a revenue limit: earn more than it and you fall out of the exemption. Illinois's $50 is a limit on what the county may charge you. The current Section 4 text sets no statewide dollar cap on sales.

The legislative history is worth a moment, because it is why the figures in circulation disagree. The source note on the section shows Public Act 104-417, effective 15 August 2025, and no prior cap is identified on the Legislature page. So, if you have seen an Illinois cottage food sales cap quoted anywhere, check whether it was written before that date before you plan around it.

For the same reason, read the enacted text rather than a bill summary or an older public act. The Illinois General Assembly's Legislative Information System is where to check whether anything has changed since.

The certified food protection manager, which is the real entry cost

Here is the requirement that changes the arithmetic. Under Section 4, every person preparing or packaging a cottage food product must be a Department-approved certified food protection manager.

Read that against the fee. The registration is at most $50. The certification is a person, a course and an exam, and it attaches to everyone who touches the packing step, not just to the owner. For a one-person operation that is one certificate. For a family operation with two people cutting and clamshelling on a Friday night, read the sentence again.

Illinois's broader Food Code layer, at 77 Ill. Adm. Code 750, makes basic food handler training apply to food handlers generally, usually within 30 days of employment. That is the wider rule for food establishments. For a microgreens grower on the cottage food route, the manager requirement in the cottage statute is the controlling one.

That inverts the usual budget. In most states the paperwork is the cost and the training is optional. In Illinois the registration is nearly free and the qualification is the expensive part, in time as much as money, so start it before you commit to a market season.

The living tray, which the definition may not reach

If you sell trays with the plants still growing, read this before you take the order.

Section 4 defines a microgreen as a seedling harvested above the substrate line. A tray sold with the plant still growing has not been harvested at all at the moment of sale, so it does not obviously fit the defined product the section is built around. The cut, packed clamshell is the thing the statute plainly describes, and the living tray is the thing hanging off the edge of it.

IDOA's farmers market guide settles one version: greens "harvested from medium on site during the farmers market are considered an agricultural product", so cutting a tray at your stall puts you on the raw route. A tray the customer takes home still growing is the open question.

That is not a prohibition, whatever it looks like at first reading. It is an open definitional question, and the statute answers it nowhere. Get the category and the labeling for a living tray from your local health department before you sell one, and get it in writing, because the answer decides whether you register under Section 4 or under something else entirely.

The awkward part is that the definition creating the gap is the same one giving you the carve-out, so you cannot argue your way around one without losing the other. Ask, and get the answer in writing.

Food safety, inspections and water

Illinois's additional layer is chiefly the adopted 2022 FDA Food Code plus local health department regulation of retail food establishments. Section 3.3 of the same Act supplies a uniform statewide scheme for farmers markets while leaving enforcement local, which is why the rules feel state-level and the inspector feels county-level.

Inspection frequency is not published as a single statewide schedule for a cottage food microgreens grower. Section 4 instead names the triggers. An inspection is authorized after:

Retail food establishments, by contrast, are inspected by their local department on the risk-based report. So, the cottage food route trades a routine inspection cycle for a complaint-driven one, which is a genuinely different regulatory posture and worth knowing before you assume nobody is coming.

Water. For a cottage food operator on a private well, the local health department may require a water sample meeting E. coli and coliform public safety standards. No statewide annual frequency is set. If your farm is federally covered and is not a sprout operation, the newer federal rule uses a systems-based agricultural water assessment with compliance dates set by farm size, rather than a simple universal annual test. Build your testing from the risk assessment, with the local department's view on the well.

The federal figures, from FDA rather than from any state page. The current three-year 2023 to 2025 values are $34,324 for the not-covered farm test and $686,476 for the qualified exemption, taken from the column headed "Average 3 Year Value for 2023 - 2025". FDA prints single-year 2025 values of $35,247 and $704,950 beside them; those are a different measure and are not the three-year figure. Do not substitute the old $25,000 in 2011 dollars for an Illinois licensing threshold either. It was never one, and Illinois does not use it.

Training and readiness. Illinois Extension runs produce safety education, tells growers to determine whether they are covered, qualified exempt or excluded, and advertises Produce Safety Alliance training. Whether Illinois offers a free formal On-Farm Readiness Review is not published. Ask Illinois Extension Food Safety at extension@illinois.edu, or IDPH Foods, Drugs and Dairies on 217-785-2439.

Labeling

On the raw route, IDOA lists no label for greens in an unsealed bag. On the cottage food route, Section 4 writes the label for you, and it is longer than most produce growers expect.

Two structural points sit around that list.

It must be prepackaged, unless the local department in the jurisdiction where you are selling authorizes another conspicuous written notice instead. That is a permission to ask for, not an assumption to make.

On "Keep Refrigerated": no separate universal refrigeration statement is stated for packaged microgreens in Section 4. The law does require time and temperature control for safety foods to be held and transported at Food Code temperatures. So, do not omit a handling statement if your local department classifies your particular product, packaging or processing as needing one. Ask with the actual package in front of you.

Tax, and the grocery tax that just went away

Illinois's former statewide 1 percent grocery tax was eliminated on 1 January 2026, per the Department of Revenue. Fresh microgreens sold as grocery food are no longer subject to it.

The catch is local. A city or county may impose an exactly 1 percent local grocery tax by ordinance, so the correct answer depends on where the sale physically happens. Do not print "tax free" on anything statewide.

Registration is a separate question from taxability. IDOR still says a person selling tangible personal property at retail must register and receive a Certificate of Registration. Use a CRT-61 only where a buyer claims a purchase is for resale, and retain it for at least three and a half years.

On inputs, Illinois has agricultural exemptions for qualifying farm machinery and equipment. IDOR's sales tax audit manual defines horticulture as producing vegetables and vegetable plants, rather than retail sale by an outlet that does not grow them. Qualification turns on the actual purchaser and the actual use, not on the word farm in your business name. Verify the equipment list and the exemption certificate with IDOR before you buy the rack.

Business setup

Illinois does not require a sole proprietor selling under their own legal name to form an entity. An LLC is a business decision.

Both figures confirmed 7 August 2026, and both are fixed fees rather than inflation adjusted. Register the retail activity with IDOR separately, as applicable.

Selling channel by channel

Farmers markets. Start with IDOA's list: microgreens "only cut for harvesting, minimally rinsed to remove visible soil" are allowed "with no restrictions", in unsealed bags or containers, when not sold as ready to eat. Raw microgreens also do not appear among the products that trigger a local Farmers' Market Permit, which is aimed at frozen potentially hazardous food, meat, poultry, dairy and eggs. Section 3.3 supplies a uniform statewide scheme, and the state preempts local market rules more stringent than its uniform provisions, which is a real protection worth knowing. What a market or municipality can still control is time, place and manner. Ask each market for its insurance, fee, booth, traceability and cooler rules, and take specific product questions to the local health department where the sale occurs.

Restaurants. Resale ends cottage food eligibility outright. The raw route is a different question: IDOA's guide says that "aside from raw agricultural products", goods for wholesale distribution need an IDPH-inspected facility, so raw greens cut only to harvest are not automatically a facility question. Ask your local health department with the product in hand. Section 4 requires the product to be sold directly for the consumer's own consumption, "not for resale". So, a restaurant sale is not a bigger version of a market sale, it is a different legal regime. You will need the required approved and regulated production and distribution setup, arranged with the local health department where your facility sits, plus whatever the restaurant's own receiving standard demands.

Grocery. Same legal answer, plus a commercial one. Grocery buyers commonly impose a written vendor agreement, a product specification sheet, lot and harvest traceability, recall contacts, temperature and packaging standards, a certificate of insurance, and often third-party GAP or GFSI evidence. None of that is a published Illinois microgreens mandate. Illinois Extension lists USDA GAP and GHP among available audit programs, which makes it the credible route when a buyer asks. Get the buyer's written vendor packet before you spend money on an audit nobody asked for in writing.

Online. Illinois cottage food may be sold online, direct to consumers. Three conditions travel with it: only non-TCS cottage products may be shipped, packages must be tamper evident, and cottage products may not be shipped out of state. That last one is a hard boundary on a business model, so decide early whether your growth plan depends on shipping. For interstate wholesale the cottage route is simply unavailable, and the receiving jurisdiction's requirements apply along with federal ones.

Home growing and zoning

Illinois has a Garden Act at 505 ILCS 87 protecting cultivation of vegetable gardens on your own property, or with permission. It is a real protection and it is a narrow one. It preserves generally applicable rules on height, setbacks, water, fertilizer, invasive species and similar matters, and it does not authorize commercial packing, delivery, customer pickup, signage, parking or a retail use at a residence.

So, the Garden Act protects the growing. It does not protect the business around the growing. Check the municipal or county zoning administrator, and your lease or HOA covenants, before you install commercial-scale racks or start receiving customers at the door.

A dedicated commercial facility is triggered when you move outside the eligible cottage food model. That means restaurant or grocery resale, processing that turns the product into a differently regulated food, or a local department's retail food determination on your setup. Whole direct-sale microgreens have a Section 4 route. A wholesale facility should get a written local determination first, not after the fit-out.

Right to farm applies, with limits. The Farm Nuisance Suit Act at 740 ILCS 70 treats land used for growing or harvesting crops, or for horticultural use, as a farm. After more than one year of non-nuisance operation, later changes in the surroundings cannot make it a nuisance, unless negligent or improper operation creates the nuisance. It is a nuisance defense. It waives nothing in zoning, food, water or pollution law.

Insurance

No Illinois source checked states that a direct-sale microgreens grower must carry commercial general or product liability insurance. No statewide mandate is published. Ask IDPH Foods, Drugs and Dairies on 217-785-2439 and your local health department.

Carry it anyway. Product liability and general liability are the baseline, and if you deliver, add commercial auto or hired and non-owned auto cover. A single alleged foodborne illness claim outruns a small grower's resources quickly.

Buyers add their own layer, and it is contractual rather than statutory. Restaurants and grocers commonly require a certificate of insurance naming them as additional insured, minimum product liability limits, indemnity and recall provisions, traceability, consistent pack and temperature specifications, invoices and food safety documentation. Negotiate those before you agree to supply, and never present one buyer's requirement to another buyer as Illinois law.

What Illinois does not publish

The market

Illinois offers dense direct-market opportunity in the Chicago metro and around its other urban and university centers, but it is not a single statewide price or demand pool. Illinois Extension notes that microgreens turn up on restaurant menus and at farmers markets and describes them as carrying a "hefty price tag". That supports a premium-positioning hypothesis. It is not a price point, and no verified statewide price band exists to publish.

Validate it the slow way: visit the target markets, sample restaurant demand, and track competitor SKUs, tray sizes and harvest frequency before you buy capacity.

The strategic read follows directly from the rules, and Illinois pushes you into a clear sequence.

Start direct, and start cheaper still. Raw greens cut only to harvest and sold in unsealed bags need no registration at all. If you move to sealed or ready-to-eat packs, the registration is capped at $50, there is no sales ceiling in the current section to grow into, and the listed channels are generous: farmers markets, online ordering, home and farm pickup, delivery and mobile farmers markets. A grower can build real volume on this route without ever triggering a facility conversation, which is unusual. Most states either cap your revenue or license your building.

Budget the certificate before the crop. The certified food protection manager requirement is the actual barrier to entry, and it is a person rather than a payment. Sort it before you commit to a market season, not during one.

Decide about wholesale deliberately. The wall in Illinois is not a dollar figure, it is the word resale. Direct sales scale freely; the first restaurant order moves you into a different regime entirely, and it does so with no warning band on the way in. Get the local department's written classification of your packing setup before you quote a chef, not after.

On funding, the state's Farm to Food Bank program supports Illinois agricultural products through the emergency food system. It is a market channel and a program, not a general startup grant. Check each grant's current eligibility rather than assuming anything is open.

Frequently Asked Questions

Q: Do I need a license to sell microgreens in Illinois? A: Not a license, and for raw greens cut only to harvest, sold in an unsealed bag or container and not as ready to eat, no registration: IDOA's farmers market guide lists them as allowed with no restrictions. For sealed or ready-to-eat product you register as a cottage food operation with your State-certified local health department, which issues a certificate with a registration number under 410 ILCS 625/4. It renews annually and the local fee is capped at $50.

Q: Are microgreens not just cut leafy greens, which the law prohibits? A: No, and this is the whole point of the Illinois answer. Section 4 defines a microgreen separately and expressly excludes microgreens from leafy greens. It also prohibits sprouts, and the definition does not turn a water-grown sprout into a microgreen.

Q: What is the sales limit? A: The current Section 4 states none. The $50 you have read about is a ceiling on what your county may charge you to register, not a limit on what you may sell. If you have seen a cap quoted, check whether it predates Public Act 104-417, which took effect 15 August 2025.

Q: Can I sell to restaurants? A: Not on this route. Cottage food must be sold direct for the consumer's own consumption, "not for resale", and a restaurant buys to resell. You would need an approved regulated production and distribution setup, arranged with the local health department where your facility sits.

Q: Do I need a food safety qualification? A: On the cottage food route, yes. Every person preparing or packaging a cottage food product must be a Department-approved certified food protection manager. Selling raw greens cut only to harvest in unsealed bags does not bring that requirement. Budget for it, and remember it applies to each person who packs, not only to the owner.

Q: Can I ship my microgreens? A: Only within Illinois, only if the product is non-TCS, and only in tamper-evident packaging. Cottage food products may not be shipped out of state, which is a real constraint on any mail-order plan.

Q: What about a living tray of uncut greens? A: Partly settled. IDOA treats greens harvested from the medium on site at the market as an agricultural product, so cutting at your stall is fine. A tray sold still growing is not addressed. Section 4's definition describes a seedling harvested above the substrate line, and a growing tray has not been harvested at the moment you sell it, so the carve-out may not cover it. Ask your local health department for the category in writing before you sell one.

Q: Do I charge sales tax? A: The statewide 1 percent grocery tax was eliminated on 1 January 2026, but a city or county may impose an exactly 1 percent local grocery tax by ordinance, so it depends on where you sell. Registering with IDOR and receiving a Certificate of Registration is a separate obligation from whether the product is taxed.

Final thoughts

Illinois is one of the few states where the legislature clearly knew this crop existed. The definition in Section 4 is specific, it is deliberate, and it does exactly the job a grower needs: it separates microgreens from the two categories that would otherwise catch them.

Three things to carry. First, check whether you need the cottage food route at all: raw greens cut only to harvest, in unsealed bags and not sold as ready to eat, are on IDOA's no-restrictions list. If you do need it, the number that matters is not $50, it is the certified food protection manager requirement, because that is the thing that takes time rather than money. The wall in this state is the word resale, not a revenue figure, so plan your channels rather than counting your takings. And if you intend to sell living trays, treat that as an open question and get your local health department's answer in writing, because the same definition that protects your clamshell is the one that leaves your tray outside.

If something here does not match what your local health department or IDPH told you, report it and it gets corrected. A page that is wrong about a rule is worse than no page.
