The Formula
Illinois sales tax is calculated by applying the combined rate to the purchase price:
Total Price = Purchase Price + Sales Tax
Where:
Combined Rate = State Rate (6.25%) + Local Rate (varies by city)
Local Rate = 1.50% to 4.75% depending on municipality
Combined Range = 6.25% to 11.00%
For groceries (2026):
State Rate = 0% (eliminated)
Grocery Tax = Local grocery rate only (1% to 3.5%)
Example: $100 purchase in Chicago (10.25% combined)
$100 × 0.1025 = $10.25 tax = $110.25 total
The state rate of 6.25% applies uniformly across Illinois. Local rates are set by individual municipalities, counties, and special taxing districts. Your exact rate depends on your specific address.
Example
James — Shopping in Chicago, IL
James buys a $500 TV and $150 in groceries at a Chicago store. He wants to understand the tax on each purchase and the total impact of the 2026 grocery tax change.
TV purchase (general merchandise)
Grocery purchase (reduced rate, 2026)
James pays $51.25 in tax on his TV (10.25% combined) and $4.50 on groceries (3.00% local only). Before 2026, the groceries would have been $6.00 in tax (4.00%) — the elimination of the state grocery tax saves him $1.50 on this trip.
