Homestead exemption
Illinois's General Homestead Exemption (GHE, 35 ILCS 200/15-175) reduces a primary residence's equalized assessed value (EAV) by up to $10,000 in Cook County, $8,000 in counties contiguous to Cook (DuPage, Kane, Lake, McHenry, Will), and $6,000 in all other counties. It is not automatic in every county — homeowners typically must apply once with their county assessor/supervisor of assessments (Cook County re-verifies periodically); Cook County has since moved to an auto-renewal system for many existing recipients. Illinois also offers several other exemptions not modeled here that can stack with GHE for eligible households: the Senior Citizens Homestead Exemption, the Senior Citizens Assessment Freeze, the Home Improvement Exemption, and the Homestead Exemption for Persons with Disabilities.

First-time buyer / down payment assistance programs

  • IHDAccess Home

    Illinois Housing Development Authority's flagship first-time (and veteran/targeted-area) homebuyer product: a 30-year fixed-rate first mortgage (FHA, VA, USDA-RD, or conventional) paired with down payment/closing-cost assistance of 6% of the purchase price, up to $15,000, as a 0%-interest second mortgage. Repayment is deferred up to 30 years and due only when the home is sold, refinanced, or no longer owner-occupied.

  • IHDAccess Forgivable

    IHDA down payment/closing-cost assistance alternative to Access Home: a forgivable second mortgage equal to 4% of the purchase price, up to $6,000, with no monthly payment and no repayment owed if the borrower remains in the home through a 10-year forgiveness period. Paired with the same 30-year fixed-rate first mortgage options (FHA/VA/USDA-RD/conventional); open to first-time and repeat buyers statewide.

Closing Costs in Illinois: What You'll Actually Pay

  • Illinois's state real estate transfer tax is $0.50 per $500 of price, or 0.1% — just $315 on the statewide median sale price of $315,000.
  • That state rate is one of three layers: counties may add $0.25 per $500 (0.05%), and home-rule cities can add their own, so the headline number understates most sales.
  • In Chicago the layers stack to roughly 0.9% combined — state $315, Cook County $157.50, and the city's $3.75 per $500 adding $2,362.50, for $2,835 on a $315,000 sale, nine times the state-only figure.

Illinois has one of the friendliest-looking transfer tax rates in the country. The state charges $0.50 per $500 of sale price — 0.1%. On the statewide median sale price of $315,000, that's $315. Not $3,150. Three hundred fifteen dollars.

Then you find out that number is the bottom layer of a stack.

Illinois counties may add their own transfer tax of $0.25 per $500, another 0.05%. Home-rule municipalities can layer a third on top of both. Chicago's is $3.75 per $500 — 0.75%, seven and a half times the state rate by itself. Put all three on a $315,000 Chicago sale and you get roughly 0.9% combined, or $2,835: exactly nine times the state-only figure, decided by which side of a city line the house sits on.

For buyers, the saving grace is that Illinois transfer tax is customarily the seller's cost — though "customarily" is doing real work there, and one Chicago tier is billed to the buyer. Below is where Illinois money actually goes. For how the individual fees work, start with our line-by-line breakdown of closing costs and use this as the Illinois overlay.

A note before you start: this is general education, not financial, legal, or tax advice. Every figure below is a statewide number from CalculatorByState's sourced dataset, and your county, municipality, lender, title company, attorney, and contract will all move the total. Illinois county and municipal transfer taxes are set locally, so the only rate that matters is the one for the address you're buying. Your Loan Estimate and Closing Disclosure are authoritative — use this to sanity-check them, not to replace them.

1. What closing costs actually run in Illinois

Illinois buyer closing costs typically run 2% to 5% of the purchase price. Against the $315,000 statewide median, that's roughly $6,300 to $15,750, midpoint near $11,025. On a $350,000 purchase the same range becomes about $7,000 to $17,500. These exclude agent commissions.
