Chicago Transfer Tax Guide for FSBO Sellers (2026)

Chicago has one of the most layered real estate transfer tax structures in the United States. For FSBO sellers in the City of Chicago, understanding exactly who pays what — and the 2023 referendum changes — is essential for accurate net proceeds calculation. Suburbs have their own structures.

The Three-Layer Chicago Transfer Tax

1. State of Illinois Documentary Stamp Tax

2. Cook County Transfer Tax

3. City of Chicago Real Property Transfer Tax The City of Chicago has a tiered structure (as of 2026):

On a $500,000 City of Chicago sale, the seller's City tax is $3,750. On a $500,000 sale, combined seller-side taxes (City + County + State) total approximately $4,500.

Note: The tiered buyer-side tax was approved via voter referendum in 2023. The higher-tier rates apply to buyers on transactions above the thresholds. As a seller on a sub-$750k transaction, your exposure is primarily the standard seller-side City tax.

Chicago Suburb Transfer Taxes

Many Chicago suburbs impose their own municipal transfer taxes on top of the state and county layers. Sellers in Evanston, Oak Park, Wilmette, and other municipalities pay additional municipal transfer taxes. Always confirm your specific municipality's transfer tax before closing.

Confirm your specific suburb's requirements with your Illinois real estate attorney.

What Goes into Your Net Proceeds Calculation

For a $500,000 sale within the City of Chicago:

Total costs excluding buyer's agent: $8,000–$13,000 Total vs. full-service listing agent (3% = $15,000 + buyer side): Savings of $12,000–$15,000+ depending on whether buyer has an agent

RPTT Stamp and Closing Process

In Chicago closings, transfer taxes are handled via stamp purchase at the time of closing. Your attorney coordinates the RPTT stamp purchase. The state stamp is handled through the county recorder's office. This process is why Illinois residential closings typically require attorney coordination — do not attempt to navigate Chicago transfer taxes without an Illinois real estate attorney.

Cook County vs. City vs. Suburb — Which Applies?

If your property is within the City of Chicago city limits, all three layers apply: State, County, and City.

If your property is in a Cook County suburb within Chicago city limits (unincorporated areas have no municipal tax), or in another collar county (DuPage, Lake, Kane, Will), you pay State + County taxes, plus any municipal tax for your specific suburb.

The easiest way to confirm: your Illinois real estate attorney will calculate the exact transfer taxes based on your property address at closing.
