The sales tax rate in Sycamore, IL is 8.00% on most retail purchases. That total combines Illinois’s 6.25% state rate with 1.75% in local taxes imposed by the city and DeKalb County.1Illinois General Assembly. Illinois Compiled Statutes 35 ILCS 120/2-10 – Rate of Tax Groceries, medicine, and vehicles follow different rules, and a 2026 change to the state grocery tax has shifted what shoppers pay at the register.
Where the 8.00% Comes From
Illinois charges 6.25% on retail sales of tangible personal property statewide.1Illinois General Assembly. Illinois Compiled Statutes 35 ILCS 120/2-10 – Rate of Tax The other 1.75% is local. Sycamore is a home rule municipality, which lets it impose a retailers’ occupation tax in quarter-percent increments on general merchandise sold within city limits.2Legal Information Institute. Illinois Admin Code Title 86, Section 270.101 – Nature of the Home Rule Municipal Retailers Occupation Tax DeKalb County adds its share on top.

Groceries After the 2026 Change
Starting January 1, 2026, Illinois eliminated its 1% state sales tax on qualifying groceries.4Illinois Department of Revenue. FY 2026-11, Municipal and County Grocery Occupation Tax Rate Changes Qualifying grocery items are foods meant to be eaten off the premises where they’re sold, which covers most of what you find in the aisles and refrigerated sections of a supermarket. The state portion on those items is now zero.
The same law lets municipalities and counties impose their own 1% local grocery tax by ordinance.4Illinois Department of Revenue. FY 2026-11, Municipal and County Grocery Occupation Tax Rate Changes Whether Sycamore or DeKalb County enacted that local grocery tax determines what you actually pay. Check with city hall or the Tax Rate Finder for the current local grocery rate at your store.3Illinois Department of Revenue. Tax Rate Database
What Still Gets Taxed at the Full Rate in a Grocery Store
Several categories sold alongside groceries don’t qualify for the reduced treatment. They stay at the full 6.25% state rate plus applicable local taxes:
- Candy, defined as sugar, honey, or other sweeteners combined with chocolate, fruits, nuts, or flavorings in bar, drop, or piece form. An item containing flour, or one that requires refrigeration, isn’t candy under this rule.5Illinois Department of Revenue. Are Sales of Candy Taxed the Same as Other Food?
- Soft drinks.
- Alcoholic beverages, regardless of where you buy them.
- Prepared food, meaning anything sold heated, heated by the seller, or served with eating utensils. Restaurant meals, takeout, and ready-to-eat deli items all fall here.1Illinois General Assembly. Illinois Compiled Statutes 35 ILCS 120/2-10 – Rate of Tax
The flour test on candy catches people off guard. A chocolate bar is candy. A chocolate chip granola bar containing flour isn’t.
Medicine and Medical Appliances
Prescription and nonprescription medicines, medical appliances, insulin, blood sugar testing supplies, and syringes used by diabetics all carry a state rate of just 1%.1Illinois General Assembly. Illinois Compiled Statutes 35 ILCS 120/2-10 – Rate of Tax That reduced rate also covers Class III medical devices used for cancer treatment under a prescription, along with their accessories and components, and vehicle modifications that make a car usable by a person with a disability.
These items are exempt from Sycamore’s home rule sales tax, so 1% is essentially what you pay. The distinction worth knowing: items that replace or support a body function (corrective lenses, prosthetics, hearing aids) qualify, while cosmetics and toiletries pay the full general merchandise rate even when sold at a pharmacy.
Vehicles and Other Titled Property
Cars, trucks, trailers, and other property that must be titled or registered with a state agency follow a different path. Sycamore’s home rule retailers’ occupation tax specifically excludes titled property.2Legal Information Institute. Illinois Admin Code Title 86, Section 270.101 – Nature of the Home Rule Municipal Retailers Occupation Tax The city portion of the 8.00% rate doesn’t apply to a vehicle purchase. The 6.25% state rate still does, along with any county taxes that reach titled items.

Private party sales work differently. You report the purchase on Form RUT-50 when you apply for the title at a driver’s license facility or currency exchange, and the form is due within 30 days of the purchase date.7Illinois Department of Revenue.

Extra Sycamore Taxes on Specific Purchases
Beyond the general 8.00% rate, Sycamore layers additional taxes on a few categories:
- A 2% restaurant, bar, and packaged liquor tax on alcoholic beverages and prepared food for immediate consumption. This is in addition to the regular sales tax, not a replacement for it.10City of Sycamore. Taxes and Fees
- A $0.05 per gallon motor fuel tax collected by fuel retailers within city limits.10City of Sycamore. Taxes and Fees
- A 5% hotel and motel tax on room rentals for each 24-hour period or any portion of one.10City of Sycamore. Taxes and Fees
If you eat out regularly in Sycamore, that 2% stacks on top of the standard sales tax that already applies to prepared food.
Buying From Out of State
When an out-of-state seller doesn’t charge Illinois tax, or charges less than the Illinois rate, you owe use tax on the difference. The use tax mirrors the sales tax: 6.25% on general merchandise and 1% on qualifying drugs and medical appliances.11Illinois Department of Revenue. Use Tax for Individuals – Questions and Answers Most major online retailers now collect Illinois tax automatically, but smaller sellers and items you bring back from a trip can still trigger the obligation.
One exception: if you bought something outside Illinois and used it in another state for at least three months before bringing it home, no use tax applies.
