What You Pay on Groceries, Medicine, and Medical Appliances

What You Pay on Restaurant Meals and Drinks

What You Pay on Cars and Other Titled Property
Vehicles, watercraft, aircraft, trailers, and mobile homes follow different rules because they must be titled or registered with a state agency. The tax is based on where the buyer lives, not where the dealership sits.7Illinois Department of Revenue. Sales and Use Taxes A Palatine resident who buys a car in another town still owes tax at the Palatine rate, and the dealer typically collects it and reports the sale on Form ST-556.
Palatine’s own 1% home rule tax explicitly excludes titled or registered property.3Palatine Code of Ordinances. Palatine Code of Ordinances – Chapter 17 – Taxes So a Palatine resident’s vehicle purchase includes the state, county, and RTA components but not the village share.
What Online Sellers Charge Palatine Buyers
Out-of-state businesses shipping to Palatine addresses owe the same combined rate as local retailers once they cross Illinois’s economic nexus threshold. As of January 1, 2026, that threshold is $100,000 in cumulative gross receipts from Illinois buyers during the preceding 12-month period. The old alternative of 200 separate transactions has been eliminated.8Avalara. Economic Nexus by State Guide

Collecting and Filing Palatine Sales Tax
Businesses selling in Palatine have to register with the Illinois Department of Revenue before the first sale, not after. Registration runs through MyTax Illinois at mytax.illinois.gov, and the resulting Certificate of Registration identifies which taxes the business is responsible for.9Illinois Department of Revenue. Business Registration
Retailers file on Form ST-1. The Department of Revenue assigns the filing frequency: monthly returns are due on the 20th of the following month, quarterly returns on the 20th of the month after the quarter ends, and annual returns on January 20th of the following year.7Illinois Department of Revenue. Sales and Use Taxes Higher-volume businesses are typically placed on monthly filing, and any business with an average monthly tax liability of $20,000 or more also owes quarterly estimated payments. The state collects the full combined amount through MyTax Illinois and then distributes each jurisdiction’s share to the state, Cook County, the RTA, and the village.
Penalties for Late Filing or Late Payment
The Uniform Penalty and Interest Act sets the consequences, and they escalate quickly:
- Late filing carries a penalty of 2% of the tax due, capped at $250. If the return still isn’t filed within 30 days after the Department mails a nonfiling notice, an additional penalty of the greater of $250 or 2% of the tax shown on the return applies, capped at $5,000.10Illinois General Assembly. Revenue 35 ILCS 735 Uniform Penalty and Interest Act
- Late payment within 30 days of the due date is a 2% penalty on the unpaid amount. After 30 days, the penalty jumps to 10%.10Illinois General Assembly. Revenue 35 ILCS 735 Uniform Penalty and Interest Act
- Interest accrues on unpaid tax at the underpayment rate set under Section 6621 of the Internal Revenue Code, which adjusts quarterly.
The gap between 2% and 10% is the one to watch. Filing an accurate return on time, even without full payment, at least avoids stacking the filing penalty on top of the payment penalty, and catching a missed payment inside the 30-day window keeps the cost to a fifth of what it becomes on day 31.
