Understanding Clark County Tax Rates

The sales tax structure in Clark County, Illinois, is built on a three‑tier system. The state of Illinois imposes a base sales tax of 6.25%, which applies to most taxable goods and services. County and municipal governments may add their own taxes on top of this base rate. In Clark County, the county tax is 1.25%, bringing the combined rate to 7.50% for most items. Certain incorporated cities within the county—such as Alton, Carterville, and Sycamore—can impose an additional 0.25% municipal tax under special category districts, pushing the local rate to 7.75% in those areas.

When it comes to income tax, Illinois levies a flat state income tax of 4.95% on all taxable earned income. County or city income taxes are not applied in Clark County. Therefore, residents—or businesses—should consider the 4.95% flat rate as the primary income tax obligation in addition to any applicable sales tax on purchases.

What's Taxable in Clark County?

Recent Rate Changes

Sales tax rates can shift due to local ballot measures, state legislative action, or the creation of special districts that add an extra percentage to the standard rate. For instance, a municipal referendum in a Clark County city could introduce a new 0.25% tax to fund a transportation project. Additionally, the Illinois Department of Revenue periodically updates exemption lists and the thresholds for clothing sales. Because rates can adjust on an annual basis or mid‑year depending on ballot outcomes, it is prudent to verify the current rate with the Illinois Department of Revenue’s online rate lookup tool or by contacting the county’s tax office.
