The IDPH fee table
An Illinois medical cannabis card costs $50 for one year, $100 for two years or $125 for three years, paid to the Illinois Department of Public Health. Minor patients pay the same. Reduced-fee patients pay $25, $50 or $75 for the same three terms.
| Registration type | 1 year | 2 years | 3 years |
|---|---|---|---|
| Regular patient (adult or minor) | $50 | $100 | $125 |
| Reduced-fee patient | $25 | $50 | $75 |
| Designated caregiver (each) | $25 | $50 | $75 |
| Life-long renewal patient | not offered | not offered | $50 |
| Terminally ill applicant (under the Act) | Waived | Waived | Waived |
The term choice is a small arbitrage. Three one-year cards add up to $150, so the three-year card saves $25. The two-year card saves nothing over two one-year cards. If you expect to stay on the program, three years is the cheapest monthly rate IDPH sells: about $3.47 a month.
Who gets the reduced fee
IDPH confirms one group by name: veterans with an honorable or general discharge who are eligible for VA services and benefits. They submit a DD-214 showing service dates and a discharge other than dishonorable. The Illinois veterans page covers that, plus the VA medical records route that replaces the written certification for veterans treated at the VA.
Certain other groups may qualify; IDPH lists them. We couldn't verify that list from an official page, so check it with IDPH before you pay the full rate.
Adding caregivers
Each designated caregiver adds $25 a year. IDPH publishes the bundled totals:
| Package | 1 year | 2 years | 3 years |
|---|---|---|---|
| Regular patient + 1 caregiver | $75 | $150 | $200 |
| Regular patient + 2 caregivers | $100 | $200 | $275 |
| Regular patient + 3 caregivers | $125 | $250 | $350 |
| Reduced-fee patient + 1 caregiver | $50 | $100 | $150 |
| Reduced-fee patient + 2 caregivers | $75 | $150 | $225 |
| Reduced-fee patient + 3 caregivers | $100 | $200 | $300 |
For a minor, one caregiver is included at no charge. Rules on who can serve are on the caregivers page.
The life-long renewal fee
IDPH lists a "life-long renewal patient" fee of $50, sold only as a three-year term. The statute says IDPH can't require patients with life-long debilitating conditions to apply to renew, though it may charge renewal fees. Ask IDPH whether your condition counts before assuming you're in this group. The renewal guide walks through the cycle.
Now the other side of the ledger
Since September 10, 2026, a registered patient buying within the allotment at a medical-licensed dispensary pays:
- No Cannabis Purchaser Excise Tax. Adult-use buyers pay 10% on cannabis at or below 35% adjusted THC, 25% above 35%, and 20% on infused products.
- The qualifying-drug sales tax rate (1% state, plus local) instead of the 6.25% general state rate.
- No municipal or county cannabis tax. Those run up to 3% in municipalities and up to 3.75% in unincorporated county areas.
For plain flower, the floor on that saving is 10 points of excise plus a 5.25-point state rate gap: 15.25% of what you spend. That's the figure the calculator uses. The September change is covered in detail in our guide to the 2026 patient tax exemption.
Fees are from the IDPH fee table; the evaluation price is set by the provider. The saving uses 15.25% of your spend: the 10% Cannabis Purchaser Excise Tax on flower at or below 35% THC, plus the 5.25-point gap between the 6.25% general state rate and the 1% qualifying-drug rate. Local cannabis taxes (up to 3% to 3.75%) and the higher excise on concentrates and infused products are left out, so your real saving can be higher. The patient exemption applies from September 10, 2026, at medical-licensed dispensaries, within your allotment.
Worked examples
Using the 15.25% floor and the $50 one-year fee, before your evaluation price:
| Monthly flower spend | Saved per month | Saved per year | Months to cover $50 |
|---|---|---|---|
| $50 | $7.63 | $91.50 | 6.6 |
| $100 | $15.25 | $183 | 3.3 |
| $200 | $30.50 | $366 | 1.6 |
| $300 | $45.75 | $549 | 1.1 |
To include the evaluation, add its price to the fee and divide by your monthly saving. If a practitioner quotes you a price P, months to break even = ($50 + P) / (monthly spend × 0.1525). If you mostly buy infused products, the excise you skip is 20%, so swap in 0.2525. Concentrates above 35% adjusted THC carry the 25% rate, so use 0.3025.
The exemption applies only at dispensaries holding a medical license and only within your 2.5-ounce, 14-day allotment. A patient who buys at an adult-use-only store pays the adult-use taxes like anyone else.
Need the certification first?
IDPH won't open your application until an Illinois practitioner certifies you. Book an online evaluation with a licensed practitioner; code DRWDY85872 takes 5% off. The practitioner, not the booking site, decides whether you qualify.
Book an Illinois evaluation →Costs the table leaves out
The practitioner's evaluation fee is set by the provider, not the state. The adult application needs a passport-style photo, which you supply. Free help with the application is available at county and local health departments. If the numbers above look thin at your spend, the medical vs adult-use comparison lists the non-tax reasons people register, and you can start the application once you've decided.
Questions people ask
Is the three-year card cheaper?
Yes. Three one-year cards would cost $150; the three-year card costs $125. The two-year card at $100 costs the same as two one-year cards.
Who pays the reduced fee?
IDPH confirms that veterans with an honorable or general discharge who are eligible for VA services qualify, with a DD-214. Certain other groups may qualify; IDPH lists them.
Does the calculator include local cannabis taxes?
No. It counts only the 10% excise on flower at or below 35% THC and the 5.25-point gap in state sales tax. Local cannabis taxes of up to 3% to 3.75% would make the saving larger.
What does a caregiver cost?
A designated caregiver costs $25 for one year, $50 for two or $75 for three. For a minor patient, one caregiver is included at no charge.
