How Much Are Seller Closing Costs in Illinois? (and What Percentage of the Sale Price Closing Costs Run)

You can know your net before you ever sign a listing agreement. Not a guess, not a percentage somebody threw at you in a kitchen, the actual number, built line by line from things you can look up today.

Here's what you may not realize. Selling doesn't work like buying. A buyer writes a check and feels every dollar of it. You don't write anything. The title company just hands you a smaller check, and because you never felt the money leave, most sellers never go back and ask where it went.

On a $350,000 house in Will County closing in June, the transfer tax everybody warns you about runs $525. The property tax credit nobody mentions runs about $12,576. Same closing. Same seller. One of those numbers shows up in every article on the internet, and it isn't the big one.

How much are seller closing costs in Illinois?

Plan on roughly 8 to 10 percent of the sale price if you're paying a commission, and about 5 percent if you aren't. On a $350,000 sale, that's somewhere around $35,000 all in. Strip out the commission and you're at roughly $17,400. The surprise is what's inside that second number: only about $4,900 of it is actual fees. The rest is a property tax credit you owe the buyer because of how Illinois bills taxes, and it's usually the single largest line on the page after the commission.

Why don't sellers write a check at closing?

Because everything comes out of your proceeds first.

Your buyer shows up with a cashier's check and a number they've been staring at for six weeks. You show up and sign. The title company takes the sale price, pays off your mortgage, pays every cost below, and wires you what's left. That's it.

It sounds easier, and it is. It's also why sellers underestimate this so badly. Nobody makes you feel $17,000 leaving. You just get a number that's smaller than the one in your head, and by then the house is sold.

So the math you want isn't cash to close. It's a net sheet. Same idea, opposite direction. Your buyer is solving for what they bring. You're solving for what you keep.

Run the number on your own address before you price the house

Every figure below depends on your county, your village, your closing date, and what your taxes actually are. A percentage of the sale price is a starting point. It is not your number, and if you're selling one house to buy another, the gap between the estimate and the real thing is the gap between an offer you can make and one you can't. Five years from now, what you net today is the down payment that decides which house you're sitting in.

Who pays the transfer tax when you sell a house in Illinois?

The seller does, in almost every case. Illinois charges 50 cents per $500 of the sale price, and the county adds 25 cents per $500. Together that's $1.50 per $1,000. On $350,000, you're paying $525.

Now here's the part that's worth knowing, because it comes up when somebody tells you it's the law.

It isn't. The Illinois Real Estate Transfer Tax Law taxes "the privilege of transferring title," and it never names the buyer or the seller as the party who has to pay. Read the whole article and you won't find it. What actually puts it on you is paragraph 18 of the Multi-Board contract you signed, which says transfer stamps are paid by the seller, and then adds five words most people skim right past: "unless otherwise designated by local ordinance."

Lake County says it plainly in their own consumer guide. It's collected at recording and it "may be paid by the buyer or the seller. Check your sales contract."

That matters because it's negotiable in a way people assume it isn't, and because in one town near here the contract's own escape clause is doing real work.

Does my village charge its own transfer stamp?

Almost certainly not, and that's the opposite of what most closing cost articles will tell you.

Out of the twenty-one towns I cover across Will, Cook, Grundy and Kankakee counties, exactly two charge a municipal transfer tax. Joliet charges $3 per $1,000, paid by the seller. And Channahon charges the same $3 per $1,000, except its ordinance puts it on the buyer. Section 37.77, in writing: the liability "shall be borne by the grantee or buyer."

Nineteen towns charge nothing.

There's a real reason for that, and it's not luck. An Illinois town can only impose a transfer tax on its own authority if it's a home rule municipality. Everybody else needs a referendum, and asking voters to approve a new tax on selling your house is not a winning ballot question. So Frankfort, Mokena, Peotone and most of the rest simply can't. And the home rule towns that could, like New Lenox, Lockport, Homer Glen and Shorewood, have chosen not to.

What your village actually wants from you

Here's the trade. You're probably not paying a village tax. You may still have a village step, and unlike a tax, a step has a deadline.

Here's the one worth knowing about, because it cuts the other way. Tinley Park has a real estate transfer stamp ordinance on its books, adopted back in December 2023. The village never turned it on. Ask them today and the answer is no stamp, just a final water reading before you close.

That's the whole lesson in one village. An ordinance on the books and a program actually running are two different things, and only one of them affects your closing. Call and ask what they need from you, not what they're allowed to require.

A few others:A few others:

• Monee requires a transfer inspection before you can sell. You file a notice, the village inspects, and you come out with a full certificate, a conditional one where the buyer finishes repairs within 120 days, or an "uninspected" designation. Water, sewer and garbage have to be current first.
• Palos Hills charges the seller a $50 permit and inspects the sump pump and ejector pump on every property. The permit documents anything they find and goes to closing with you. Schedule it early.
• Manteno reportedly wants a sidewalk inspection from the village and a carbon monoxide inspection from the fire department.
• Beecher charges a one-time $50 new water account fee on every residential property that changes hands.

And four of these towns don't have village water at all. Homer Glen and Orland Hills are on Illinois American. Peotone and Manteno are on Aqua Illinois. So the standard advice to call your village for a final meter reading is just wrong in those places, and if you follow it you'll waste a week finding that out.

Village requirements change quietly and they don't send anybody a notice. Confirm yours with the village directly before you set a closing date, not after.

What is the property tax proration credit, and why is it so big?

This is the line that makes your check smaller than you expected, and it's the one worth understanding before you price anything.

Illinois bills property taxes a full year behind. Your 2026 taxes don't get billed until 2027. That sounds like a break until you sell, because the year you lived there still has to get paid, and you're the one who lived there.

So at closing you credit the buyer for two separate things.

Whatever's left of last year's bill. Say you close June 1, 2026. Your 2025 bill went out in May, and neither installment has been paid yet. You lived in that house all of 2025. That whole bill is yours, and the buyer's going to be the one holding it, so you hand it over at closing.

This year, up to your closing date. January 1 through June 1 of 2026 has already accrued against a bill nobody's seen yet. It gets estimated off your last known bill.

On a $350,000 Will County house with about $8,750 a year in taxes, prorated at 105 percent, that's roughly $8,750 for last year plus about $3,826 for this year. Around $12,576, gone from your proceeds, and it isn't a fee. You're paying taxes you genuinely owe. You're just paying them all at once, on a day you weren't planning to.

The percentage is a blank, and it's a negotiation

Look at paragraph 12 of your contract. It reads "based on ____% of the most recent ascertainable full year tax bill," and somebody fills that in. Around here it's usually 105. In Cook it's usually 110. Your side will push for 100.

Now, it's tempting to treat every point above 100 as money stolen from you, and your buyer's attorney as the thief. That's not what's happening.

The credit gets calculated off a bill that's at least a year stale. If the assessment went up, or the rate went up, or you've been sitting on a senior freeze the buyer doesn't inherit, the bill that lands in their mailbox is bigger than what you handed them, and they eat the difference. Everything above 100 percent is their cushion against that. Everything below it is yours. Neither one of you is being unreasonable. You're splitting a risk that neither of you can price yet, and whoever's wrong about next year's assessment pays for it.

That said, if you've had an exemption the buyer won't get, expect them to come in high and be ready to explain why. And if your assessment looks wrong in the first place, how to appeal your property taxes in Illinois is worth reading before you list, because a successful appeal lowers the bill your credit gets calculated from. So does a Will County property tax exemption you never claimed.

Once it's signed, it's done

One more thing about paragraph 12, and it surprises people. Your prorations are final as of closing. There's no truing up when the real bill shows up. If you agreed to 110 percent and the assessment came in flat, that money's gone and you don't get it back. If you agreed to 100 and taxes jumped, your buyer absorbs it.

The exception is new construction that hasn't been taxed for a full year as built, where the contract escrows 3 percent of the purchase price instead and the two of you split the escrow fee.

If you want the fuller picture of how the assessment behind all of this actually gets built, how property taxes work in Illinois walks through it.

What does the seller pay for title insurance in Illinois?

The owner's policy, and it's the biggest actual fee on your statement. Expect roughly $2,400 to $2,600 on a $350,000 sale.

Same story as the transfer tax. No Illinois law puts it on you. Paragraph 20 of your contract does, at "Seller's expense." It's been the custom here long enough that nobody questions it anymore, and the downstate bar forms do the same thing.

But there's something in here worth real money, and almost nobody tells sellers about it.

Illinois doesn't regulate title insurance pricing. The statute specifically denies the state authority to set premiums, search fees or closing fees. Which means there's no standard rate, and the published cards from the four biggest underwriters differ by $140 to $200 on the exact same sale price. Same coverage. Same house.

And under Illinois law, whoever pays for the policy picks the company. You're paying for the owner's policy, so it's your call, and nobody in the transaction is allowed to condition their services on you using theirs. Ask what it costs. You're allowed to.

The rest of the title company's side of your statement runs smaller and adds up anyway: a settlement or closing fee around $325 to $350, a title search near $290, a $50 closing protection letter, a wire fee around $60, and a few processing charges. Call it $700 to $900 beyond the premium.

One correction while we're here, because it cuts your way. Paragraph 8 puts the escrow closing fee on the buyer when they're getting a loan. If somebody tells you that one's yours, check the contract.

Do I need an attorney and a survey to sell a house in Illinois?

Effectively yes on both, and for two completely different reasons.

The attorney isn't required by any statute. What happened is a 1966 Illinois Supreme Court case that held drawing up deeds and the other documents after the contract "requires the peculiar skill of a lawyer." So your agent can't prepare your deed. Neither can the title company. That's why every residential seller in this state hires counsel, and why people call Illinois an attorney state. Plan on $500 to $1,000 flat for most residential closings.

The survey is required, by your contract. Paragraph 21 puts a current plat of survey at your expense, delivered at least one business day before closing, dated no more than six months before the closing date. Three things sellers get wrong here:

• The survey from when you bought the house does not count. Six months means six months.
• Condominiums are excluded entirely.
• It doubles as title evidence. It's what lets the title company drop the survey exception and issue extended coverage, so it isn't optional paperwork.

Figure $400 to $700 around here.

Why is the buyer asking me to pay their closing costs?

Because they're short on cash, and asking you is cheaper for them than asking their parents.

That's the honest version. A buyer with a good income and a thin savings account can carry the payment fine and still can't get to the table. Closing costs and prepaid escrows run about 3 percent on top of the down payment, and on a $350,000 house that's another $10,500 they have to produce in cash that they don't get back.

So they ask you for a credit. And a credit costs you real money, so it's worth knowing the rules before you agree to one, because they're tighter than most people selling a house realize.

How much can a seller actually contribute?

There's a ceiling, and it's set by the buyer's loan, not by the two of you.

The top row is the trap, and it's the row your buyer is most likely in. A first-time buyer putting 5 percent down is at 95 percent loan-to-value, which caps you at 3 percent, not 6. On $350,000 that's $10,500. Agree to "6 percent toward closing costs" with that buyer and you've agreed to something their loan can't accept, and nobody finds out until underwriting, which is three weeks later and eight days before you were supposed to close.

VA works differently and it works in your favor to understand. The 4 percent cap is not a cap on paying the veteran's closing costs. You can pay 100 percent of those and none of it counts against the 4. The 4 percent bucket is for other things: the funding fee, prepaid taxes and insurance, paying off their debts, points for a buydown. So on a VA deal, write the two separately in the contract. One line that says "seller to pay $20,000" invites an underwriter to test the whole thing against the 4 percent, and you lose an argument you should have won.

And never offer a "repair allowance" on an FHA deal. A $12,000 credit toward real closing costs is fine. A $12,000 repair allowance is what FHA calls an inducement to purchase, and it cuts the value the loan is calculated from, dollar for dollar. Same money. Completely different outcome. That one kills deals.

The appraisal has to keep up

A credit comes out of the price, it doesn't lower the price. Sell at $340,000 flat and the appraisal has to hit $340,000. Sell at $350,000 with a $10,000 credit and the appraisal has to hit $350,000, because that's still the contract price.

So a credit raises the appraisal bar by exactly the amount of the credit. It works when there's room above your number in the comps. It doesn't when you're already priced at the top of the range, and finding that out from an appraiser in week four is an expensive way to learn it.

Write the credit into the contract from the start. A credit added by amendment after the appraisal is back triggers new disclosures, can cost you days on the closing calendar, and on a price-up structure the higher price has to appraise all over again.

Should you cut the price or pay the buyer's closing costs?

Run it. $350,000 house, buyer putting 5 percent down at 6.5 percent. Illustrative numbers, and rates move, but the shape holds.

The credit hands them $9,200 less cash at the table and costs them about $60 a month, forever. They'd need almost thirteen years to pay back in payments what they saved in cash. For a buyer who can't come up with $27,200, that trade isn't close. And a buyer who can't get to the table doesn't get to run the comparison at all.

What it costs you, honestly

Not nothing, and anybody who tells you it's a wash is doing your math wrong.

Your commission and your transfer tax both get calculated on the gross price, not on what you net. Cut the price and you pay 5 percent commission on $340,000. Keep the price and credit back, and you pay it on $350,000.

The credit costs you $515 more. That's the real number, and it's small enough that it usually shouldn't decide anything, but you should know it before you agree rather than after. What you get back for it: the higher price is what goes in the public record and the MLS data, which matters to the next person pricing a house on your street. And sometimes the credit is the only structure that gets the deal closed at all.

The question that actually decides it

Here's the thing nobody frames right. It isn't credit versus price cut. There are three different problems a buyer can have, and they take three different fixes.

Short on cash? A credit. That's what it's for.

Short on payment? Take the same $10,000, let them spend it on discount points instead of closing costs, and the payment goes lower than the price cut would have taken it. Roughly three points on that loan, which in a normal market buys somewhere around three quarters of a percent. That structure beats a price reduction on monthly payment and it isn't close. Even though most people don't know how interest rate buydowns work, permanent and temporary are different products with different costs.

Short on qualifying? Careful here. A 2-1 buydown on that loan runs about $7,568, which eats roughly three quarters of a 3 percent cap and leaves almost nothing for closing costs. And the buyer still has to qualify at the full 6.5 percent anyway. A buydown buys them a payment. It does not buy them an approval.

Worst case scenario, you ask which of the three it is and the answer is cash, and you write the credit. Best case, you find out it's payment, and the same ten thousand dollars buys a stronger deal for both of you. Nobody in the transaction is paid to ask that question. It takes about four minutes.

The Bottom Line

Seller closing costs in Illinois run about 8 to 10 percent of your sale price with a commission, and roughly half of what's left after the commission isn't a fee at all. It's property taxes you already owe, handed over in one piece on a day you didn't choose.

The transfer tax is $1.50 per $1,000 and almost nowhere around here adds to it. The owner's title policy is yours, it runs around $2,500, and since you're paying for it you get to pick the company. The attorney and the survey are real and predictable. The property tax credit is the one that moves the number, it's negotiated in a blank on page whatever of your contract, and it's final the moment you sign.

And if a buyer asks you to cover their costs, that's not them being cheap. It's the cash problem, and there are three versions of it. Find out which one you're looking at before you decide whether to hand back ten thousand dollars or take ten thousand off the price, because they are not the same trade and the difference shows up in your net.

Know the number before you list. Not after.

Frequently Asked Questions

Who pays closing costs on a home sale in Illinois?

Both sides pay, and they pay for different things. The seller covers the transfer stamps, the owner's title policy, the survey, their own attorney, the mortgage payoff and release, and the property tax proration credit. The buyer covers their lender's fees, their prepaid escrows, the loan title policy, the escrow closing fee, and their own attorney. And it can help you understand a buyer offer to know how much buyer closing costs actually run in Illinois.

What percentage of a home sale goes to closing costs?

About 8 to 10 percent of the sale price when you're paying a commission, and roughly 5 percent when you aren't. The commission is usually the largest single line, and the property tax proration credit is usually the second. Everything else together, title, attorney, survey, transfer stamps and recording, typically lands somewhere between $4,000 and $5,500 on a sale in this range.

Are seller closing costs tax deductible?

Some of them adjust your cost basis rather than being deducted, which is a different and often better outcome, and the rules depend on your situation. Selling costs like commission and transfer taxes generally reduce your taxable gain, and most homeowners selling a primary residence have a capital gains exclusion that covers them anyway. Talk to a tax professional about your specific sale before you assume either way.

Can I negotiate who pays the transfer tax?

Yes. The state statute taxes the transfer itself and doesn't name a party, so who pays comes from your contract, and contracts get negotiated. The standard Multi-Board form puts stamps on the seller by default. Local ordinances can override that, which is exactly what happens in Channahon, where the village puts its own transfer tax on the buyer.

What is the property tax credit at closing, and can I avoid it?

It's your share of property taxes that haven't been billed yet, credited to the buyer because Illinois bills a full year behind. You can't avoid it, because you genuinely owe the taxes for the time you owned the house. What you can negotiate is the percentage used to estimate it, which is the blank in paragraph 12 of your contract, and whether the assessment behind it is correct in the first place.

Do I need a new survey to sell my house?

Yes, in almost every case, and it has to be dated within six months of your closing date. Your contract requires it at your expense, and the title company needs it to issue extended coverage. Condominiums are the exception and don't require one. Order it early, because a surveyor's schedule is not built around your closing date.

How do I find out what my village requires before I sell?

Call the village directly and ask specifically about real estate transfer requirements, not just about your water bill. Some towns want an inspection with a waiting period, some want a permit, and a few want nothing at all. And ask what they actually require today, not what their code allows. One village near here has a transfer stamp ordinance on the books that it has never put into practice, so the code says one thing and the counter says another.

If your village changed something or asked you for a step that isn't on this page, tell me. I'd rather fix it here than have the next seller find out at their closing.
