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.
One honesty note: $315,000 is Illinois REALTORS' statewide closed-sale median for March 2026, up 6.8% year over year. Live-MLS trackers report as high as $375,000 — likely a different measurement basis, not a contradiction. Run your own price, not a median.
Closing costs are separate from your down payment, and both are due the same day. On a $315,000 purchase with 20% down you finance $252,000 and bring $63,000. Add the $11,025 midpoint: about $74,025 in cash to reach the table.
See your all-in Illinois closing costs2. The state transfer tax is the smallest layer
Illinois's real estate transfer tax, administered by the Department of Revenue, is levied on the deed transfer and collected at closing. The state rate is $0.50 per $500 of consideration: a $315,000 sale is 630 increments of $500, so $315. A $350,000 sale is 700 increments, or $350.
If Illinois stopped there, transfer tax would be a rounding error, smaller than most lender fees. It doesn't stop there. Counties may add $0.25 per $500 — another $157.50 on $315,000 — and home-rule municipalities set their own rates. No statewide table gives you your combined rate; you get it from your attorney, agent, or title company, keyed to the address.
The 0.1% on the state's own page is real. It is also almost never the whole bill.
3. Chicago is where the stacking actually bites
Chicago's municipal transfer tax is $3.75 per $500 on most residential sales, paid by the seller: 630 × $3.75 = $2,362.50 on a $315,000 sale. Stack all three layers:
- State, at $0.50 per $500 (0.1%): $315
- Cook County, at $0.25 per $500 (0.05%): $157.50
- City of Chicago, at $3.75 per $500 (0.75%): $2,362.50
- Combined, roughly 0.9%: $2,835
The combined total is nine times what the state rate alone would suggest ($2,835 ÷ $315 = 9).
A second Chicago tier is billed to buyers directly: on transactions over $1,000,000, the city adds $1.50 per $500 — 0.3%. Most Illinois buyers never meet it, but if you're shopping seven figures in the city it belongs in your cash-to-close math from the first showing. This layering is why transfer tax is the biggest city-to-city swing in what closing costs are made of.
4. No mortgage recording tax on your loan
Here's a genuine break: Illinois has no mortgage recording tax. Some states tax your loan amount when the mortgage is recorded, on top of transfer tax on the sale price. Illinois does not. Your $252,000 loan at the median triggers no percentage-based state charge — county recorders collect small, flat fees instead.
That matters most on a refinance: no sale means no transfer tax, and no tax on the new loan either. At current rates of 6.65% on a 30-year fixed and 5.95% on a 15-year, whether an Illinois refinance pencils out comes down to rate and lender fees.
5. Illinois is an attorney state in practice, not by law
No Illinois statute requires a lawyer at a residential closing. But Illinois real estate attorneys consistently describe the state as an attorney state in practice: the overwhelming majority of buyers and sellers retain one, and attorney-review periods are standard clauses in Illinois contracts. The custom is closest to universal in Cook, DuPage, Lake, Kane, and Will counties.
Two consequences. Budget for the attorney fee as a normal line item, not an optional extra; in much of Illinois, closing without one is the unusual choice. And treat attorney review as leverage — it's a window after signing to have counsel modify or, in some cases, exit the contract. Your attorney is also the person who will actually know the municipal transfer tax add-on for your address.
Title insurance works the same way here as anywhere; see what title insurance covers and who it protects.
6. Who pays what, and what you can negotiate
By Illinois custom, the seller pays the transfer tax — delivering a recordable, tax-stamped deed is the seller's obligation, so the stamps are the seller's cost. That's why the Chicago stacking in section 3 mostly lands on the other side of the table from you.
Custom is not law. No Illinois statute assigns transfer tax to either party, and it's negotiable by contract. On a contested Chicago listing, offering to absorb part of the seller's transfer tax costs the seller real money without touching the appraised value — the same reasoning behind a credit instead of a higher price.
Everything else follows the usual pattern: lender fees have room in them, third-party services you may choose can be shopped, government fees and prepaids are fixed. See the fees you can push back on.
7. How to lower the bill before you sign
- Get the combined transfer tax rate for the exact address. State plus county plus municipality is one number, and it becomes your cost the moment you offer to cover it.
- Shop lenders, not just advertised rates. Origination and underwriting charges differ on identical loans, and that spread is the largest slice of your 2-5% you actually control.
- Ask for the attorney fee up front. It's customary, it's quotable, and it varies. A flat-fee quote before you engage is a reasonable request.
- Ask for a seller credit. Where the seller already carries the transfer tax, credits are a familiar part of the negotiation.
- Reconcile your Loan Estimate against your Closing Disclosure. Some line items may move between the two and some may not; how to read a Loan Estimate line by line covers the tolerances.
And budget for prepaids. Illinois property taxes are billed in arrears, making tax proration and escrow funding a real cash item — see how escrow accounts get funded.
Frequently asked questions
How much are closing costs in Illinois?
Buyer closing costs typically run 2% to 5% of the purchase price. At the $315,000 statewide median that's about $6,300 to $15,750, midpoint near $11,025. Chicago-area purchases trend toward the higher end because of local taxes and fees. The range excludes commissions.
What is the Illinois transfer tax rate?
The state rate is $0.50 per $500 of consideration — 0.1%, or $315 on a $315,000 sale. Counties may add $0.25 per $500 (0.05%) and home-rule municipalities may add their own on top, so your combined rate depends on the address.
How much is the Chicago transfer tax?
Chicago's municipal rate is $3.75 per $500 on most residential sales, paid by the seller — $2,362.50 on a $315,000 sale. Adding the state's $315 and Cook County's $157.50 brings it to about $2,835, roughly 0.9%. On sales over $1,000,000, Chicago adds $1.50 per $500 (0.3%) that the buyer pays.
Does the buyer or the seller pay transfer tax in Illinois?
The seller pays by custom, because producing a tax-stamped, recordable deed is a seller obligation. No state law fixes this, so it's negotiable. The exception is Chicago's supplemental tier on sales over $1,000,000, charged to the buyer.
Do I need an attorney to close on a house in Illinois?
Not by law — no Illinois statute requires one. In practice it's the statewide default, and close to universal in Cook, DuPage, Lake, Kane, and Will counties, with attorney-review periods written into standard contracts. Budget for the fee.
Does Illinois charge a mortgage recording tax?
No. Illinois has no mortgage recording or intangible tax, so a $252,000 loan carries no percentage-based state tax at recording. County recorders charge flat fees instead.
Are closing costs part of my down payment?
No — they're separate, and both are due at closing. On a $315,000 Illinois home with 20% down you finance $252,000, bring $63,000 down, and add roughly $11,025 at the midpoint, for about $74,025 in cash. There are ways to reduce what you bring to the table, including seller and lender credits.
