Over-the-counter drugs and medicines are taxed at a reduced state rate of 1% in Illinois, well below the 6.25% state rate on general merchandise. Whether a specific product qualifies for the OTC sales tax rate in Illinois depends on what the label says: if the packaging claims the product treats a disease, illness, injury, or pain, it gets the 1% rate; if it doesn’t, it usually doesn’t.1Illinois Department of Revenue. Sales Tax Audit Manual Chapter 14 Local taxes can push the total higher, and a handful of related categories follow their own rules.
The Label Is What Decides
Under the state’s administrative code, a pill, powder, salve, or other preparation for human use qualifies as a drug or medicine when its label carries a written claim that it is intended to cure or treat disease, illness, injury, or pain.1Illinois Department of Revenue. Sales Tax Audit Manual Chapter 14 Aspirin, ibuprofen, cough suppressants, allergy medications, antacids, medicated skin treatments, and cold medicines are the typical examples. A generic acetaminophen bottle that says “reduces fever and relieves pain” clearly qualifies at 1%.
Products labeled only for general wellness or comfort, without any specific disease or symptom claim, sit outside the definition. Two nearly identical throat lozenges can carry different tax rates: one labeled “soothes sore throat pain” gets the 1% rate, one labeled “refreshing menthol flavor” does not. The rule is mechanical, and it turns on the printed label rather than how the product is actually used.
Prescription and nonprescription medicines, insulin, diabetic testing supplies, medical appliances, and certain cancer-treatment devices are all listed in the statute at the 1% state rate.2Illinois General Assembly. 35 ILCS 120/2-10
Vitamins And Supplements In 2026
Vitamins and dietary supplements sit in an unusual spot as of January 1, 2026. If the label carries a medicinal claim, the product is classified as a drug and taxed at the 1% state rate. If the label makes no such claim, the product is treated as a grocery item and is now exempt from the state portion of sales tax entirely.3Illinois Department of Revenue. Tax Rate Information for Retail Sales of Food and Medicine PIO-1154Illinois Department of Revenue. Illinois Grocery Tax Changes Effective January 1, 2026
A basic multivitamin with no disease-related claims on the bottle carries zero state tax. A vitamin C bottle labeled “fights colds” is taxed at 1%. Protein powders and weight-loss products follow the same logic: marketed purely as food, they are grocery items; labeled as treating a condition, they get the 1% drug rate. Local taxes may still apply either way, depending on the municipality.
Grooming And Hygiene Products Pay Full Tax
This is where most of the confusion lives. Grooming and hygiene products are taxed at the full 6.25% state rate even when they share shelf space with 1%-rate items, and the regulation excludes them from the reduced rate regardless of any medicinal-sounding language on the label.5Legal Information Institute. Illinois Administrative Code tit 86 130.311 – Drugs, Medicines, Medical Appliances, and Grooming and Hygiene Products
The list is longer than most shoppers expect:
- Hair care: shampoos, conditioners, styling products
- Oral care: toothpaste, mouthwash, breath spray
- Skin care: soaps, moisturizers, skin creams, lotions, sunscreen, suntan lotion
- Body care: deodorants, antiperspirants, shaving cream, baby powder, foot powder
- Other: acne products, contact lens solutions, hand sanitizers, lip balm, condoms, and diapers for babies and adults
Acne treatments surprise people. Even though acne is a skin condition, the regulation puts acne products in the grooming and hygiene category rather than the drug category.5Legal Information Institute. Illinois Administrative Code tit 86 130.311 – Drugs, Medicines, Medical Appliances, and Grooming and Hygiene Products Hand sanitizers land the same way. If a product appears on the grooming and hygiene list, the 6.25% state rate applies even where the label carries a medicinal claim.
Menstrual Products Are Exempt Through 2026
Tampons, menstrual pads, and menstrual cups are completely exempt from Illinois sales tax through December 31, 2026. The exemption, created by PA 99-855, applies to all four state occupation and use taxes.6Illinois Department of Revenue. Sales and Use Tax Exemption for Tampons, Menstrual Pads, and Menstrual Cups
Other feminine hygiene products such as wipes, washes, powders, and douches are not covered by the exemption and are taxed at the 6.25% general merchandise rate.5Legal Information Institute. Illinois Administrative Code tit 86 130.311 – Drugs, Medicines, Medical Appliances, and Grooming and Hygiene Products
Medical Appliances And Diabetic Supplies
Medical appliances also qualify for the 1% state rate. The rule is that the item must directly substitute for a malfunctioning part of the body. Artificial limbs, dental prostheses, orthodontic braces, crutches, orthopedic braces, wheelchairs, heart pacemakers, hearing aids, eyeglasses, and contact lenses all qualify.7Illinois Department of Revenue. Illinois General Information Letter ST 25-0008-GIL
Diabetic supplies get their own statutory line. Insulin, blood sugar testing materials, syringes, and needles used by diabetics are taxed at 1% under the statute itself rather than by regulatory interpretation.2Illinois General Assembly. 35 ILCS 120/2-10 Home glucose monitors, test strips, and related supplies also qualify.7Illinois Department of Revenue. Illinois General Information Letter ST 25-0008-GIL
A product that does not correct or replace a body function falls out of the category. A standard bathroom scale is not a medical appliance. A blood pressure cuff does not substitute for a body part either, so it is treated as general merchandise unless a more specific carve-out applies.
Local Taxes Change What You Actually Pay
The 1% state rate is a floor, not a ceiling. Home-rule and non-home-rule municipalities, the Regional Transportation Authority, park districts, county public safety districts, and other local bodies can add their own percentages on top.8Illinois Office of Comptroller. Sales Tax The total tax on an OTC drug purchase depends on where the store is located.
Prescription drugs get better treatment here. Illinois law blocks local jurisdictions from adding local tax to prescription medications, so prescriptions face only the 1% state rate statewide. Nonprescription OTC drugs don’t get that protection, so the total rate on an ibuprofen bottle or a cough syrup can be noticeably higher in high-tax areas like Chicago than in a lower-tax municipality.
Paying With An HSA Or FSA
If you’re paying with a Health Savings Account or Flexible Spending Account, the federal rules changed in March 2020. The CARES Act removed the prescription requirement for OTC medicines bought with HSA or FSA funds, so eligible items such as allergy medicine, pain relievers, and cold remedies can be purchased directly with an FSA or HSA card without a doctor’s note.9FSAFEDS. Over-the-Counter OTC Medicines or Drugs
Bandages, crutches, and blood sugar test kits were never subject to the prescription requirement, and insulin has always been HSA/FSA-eligible without a prescription. HSA and FSA eligibility is a federal question, separate from Illinois sales tax; the tax still appears on the receipt regardless of how the purchase is paid.
