Do You Pay Taxes When You Sell an Inherited House in Illinois?
If you inherit a house and sell it, you usually have to pay far less tax than you fear — and often nothing at all. You're taxed only on the appreciation that happens after the date of death, not on the decades of growth since your parents bought the place. Illinois has no inheritance tax, and the Illinois estate tax only touches estates over $4 million — and even then, the estate pays it, not you.
That's the short version — here's how each piece works, with real numbers. Full disclosure first: we're Easy Exit Home Buyers, a family-owned company in Crystal Lake that buys inherited houses across McHenry, Lake, Kane, DuPage, and northwest Cook counties. We're a direct buyer, not a licensed agent, and we're not CPAs or attorneys — treat this as orientation, and confirm your numbers with a tax professional before filing.
If I Inherit a House and Sell It, Do I Have to Pay Taxes?
Three different taxes get tangled together in this question, and most Illinois heirs only ever deal with one of them:
- Inheritance tax — a tax on the person receiving property. Illinois doesn't have one — nothing to pay, nothing to file.
- Estate tax — a tax on the deceased person's total estate before anything is distributed. The 2026 federal exemption is $15 million per person (set by 2025's One Big Beautiful Bill Act), and the Illinois estate tax starts at $4 million. Both are paid by the estate itself — never billed to you as the heir selling the house.
- Capital gains tax — the only one most heirs actually encounter, and thanks to the stepped-up basis, usually a fraction of what people expect.
So if you're searching "if I inherit a house and sell it do I have to pay taxes" at midnight: breathe. For the typical suburban estate, the answer is a modest capital gains bill or nothing.

Capital gain is normally your sale price minus what the owner paid — the "basis." Inherited property follows a friendlier rule: under Section 1014 of the federal tax code, your basis steps up to the home's fair market value on the date of death, wiping the original owner's lifetime of appreciation off the books for tax purposes.
Here's what that looks like with round numbers:
- Your parents bought the house in 1995 for $120,000.
- On the date of death, it's worth $300,000. That becomes your new basis.
- Eight months later, you sell it for $310,000.
- Your taxable gain is $10,000 — not $190,000.
| If basis didn't step up | With stepped-up basis (actual law) |
|
|---|---|---|
| Parents paid (1995) | $120,000 | $120,000 |
| Basis you're taxed against | $120,000 | $300,000 (value at date of death) |
| Your sale price | $310,000 | $310,000 |
| Taxable gain | $190,000 | $10,000 |
| Approx. federal (15%) + Illinois (4.95%) tax | $37,905 | $1,995 |
Selling costs reduce the gain further. And if the house sells at or below its date-of-death value — common when a dated house sells as-is within months — there may be no gain at all, sometimes even a deductible loss.
Order a date-of-death appraisal from a licensed appraiser, even if you're months past the funeral — appraisers can value a home retroactively. It usually costs a few hundred dollars and it's your proof of basis if the IRS ever asks.
Inherited Property Tax in Illinois: No Inheritance Tax, and an Estate Tax Most Families Never Meet
Illinois has no inheritance tax. Heirs owe the state nothing simply for receiving a house, money, or anything else from an estate.
What Illinois does have is an estate tax, under 35 ILCS 405, with a $4,000,000 exclusion. The threshold isn't indexed for inflation, and a 2025 bill to raise it (HB2601) stalled — so $4 million remains the line for 2026.
Two things matter for a seller: the tax is calculated on the entire estate — house, accounts, everything — so a $300,000 house alone gets nowhere near it, and even when it applies, the estate pays it before distribution. It never follows you to the closing table.
Illinois has no inheritance tax on heirs. The Illinois estate tax applies only to estates over $4 million and is paid by the estate itself — you will never be personally billed for it when you sell an inherited house.
Capital Gains on an Inherited House: Federal and Illinois Rates
When there is a gain above your stepped-up basis, here's the treatment:
- It's automatically long-term. Under Section 1223(9) of the tax code, inherited property counts as held over a year no matter how fast you sell — so you get long-term rates of 0%, 15%, or 20% by income, never the higher short-term rates. (Very high earners may owe an extra 3.8% net investment income tax.)
- Illinois taxes the gain too. Illinois treats capital gains as ordinary income at its flat 4.95% rate, with no long-term discount.
- You report the sale on Form 8949 and Schedule D, entering "INHERITED" as the acquisition date.
Run our example through those rates: a $10,000 gain costs roughly $1,500 federal (at 15%) plus about $495 to Illinois — around $2,000. Without the step-up, the same sale would have cost roughly $38,000. That's the stepped-up basis doing its job.
Not sure what the house would actually sell for? That number drives everything above. Request a no-obligation cash offer on the house as-is — or call or text (224) 267-9324 — for a concrete figure to run past your CPA, whether or not you sell to us.
Property Taxes: Who Pays What at Closing
Separate from income taxes, the house keeps generating ordinary property tax bills — and Illinois bills them a year in arrears: the bill that arrives in 2026 covers 2025's taxes. The estate or heirs keep installments current while holding the property.
At closing, the accrued-but-unbilled taxes are settled through a proration credit: the seller credits the buyer for taxes covering the seller's ownership period, typically at 105% of the latest bill in the collar counties (110% is common in Cook County) to cushion against increases. It comes out of sale proceeds rather than your pocket, but on a McHenry or Lake County bill it's a noticeable line item. For a local angle, see our guide to inherited property tax in Round Lake Beach.
What Changes If You Rent It Out First — or It Was in a Trust
Renting first: the home becomes investment property. You gain deductions (including depreciation) while renting, but depreciation is "recaptured" and taxed when you sell. Your basis still starts from the date-of-death value, but the math grows moving parts — firmly CPA territory.
Held in a trust: houses in a standard revocable living trust generally still receive the stepped-up basis. Irrevocable trusts vary — some are structured so assets get no step-up. And a house gifted to you before death keeps the owner's original low basis, creating exactly the $190,000-gain scenario the step-up normally prevents. Ask the estate's attorney which applies before you set a price.
Still in probate: taxes are only half the puzzle — the estate usually needs authority to sell at all. Our step-by-step guide to selling an inherited house in Illinois covers probate, title, and the order to do things in.
Once the Tax Fear Is Gone, the Real Cost Is the Wait
The taxes usually end up manageable; the carrying costs don't. Every month the house sits, it burns property taxes, insurance, utilities, and upkeep — while siblings wait on their share.
You have two honest paths. Listing with an agent typically nets the most money if the house shows well and you can fund repairs and wait out showings and financing. Selling as-is to a direct buyer like us trades some of that price for speed and certainty — our cash offers run below full market value; that's the deal, stated plainly. In exchange: no repairs, no cleanout (take what you want, leave the rest), no commissions, and a closing in as little as 7 days once title is clear — 2 to 3 weeks is typical, and probate can add time.
If the second path fits, start with our inherited house page, request your cash offer, or call or text (224) 267-9324. We'll give you a real number, explain how we got it, and you can take it to your CPA and family with zero obligation.

Frequently Asked Questions
If I inherit a house and sell it right away, do I have to pay taxes?
Usually little or nothing. Your cost basis resets to the home's fair market value on the date of death, so an immediate sale at that value produces no gain — and often a small loss once selling costs are counted. You'd owe capital gains tax only if the property appreciated between the date of death and your sale. Any gain is automatically long-term under federal law. Confirm the numbers with a CPA before you file.
Does Illinois have an inheritance tax on a house I inherit?
No. Illinois has no inheritance tax, so heirs pay no state tax simply for receiving property. Illinois does have an estate tax, but it applies only to estates worth more than $4 million and is paid by the estate before assets are distributed — the executor handles it, not you as the seller. Most McHenry, Lake, and Kane County estates fall well under that threshold and owe nothing.
How much is capital gains tax on an inherited house in Illinois?
Federally, gains on inherited property are taxed at long-term capital gains rates — 0%, 15%, or 20% depending on your income, with most sellers landing at 15%. Illinois adds its flat 4.95% income tax on the same gain. Remember, the gain is only the amount above the home's date-of-death value, minus selling costs. On a house sold within months of death, that figure is often a few thousand dollars or zero.
What if I sell the inherited house for less than it was worth at death?
You may have a deductible capital loss. If the home sells below its stepped-up basis — common once you subtract closing costs, or when a dated house sells as-is — the IRS generally treats the loss as long-term. It can offset other capital gains, plus up to $3,000 of ordinary income per year. The loss rules differ if you or family lived in the home after the death, so this is one to run past a CPA.
Do I have to report the sale to the IRS even if I owe nothing?
Yes, in almost all cases. The closing agent typically issues Form 1099-S, and the IRS expects to see the sale on your return — usually Form 8949 and Schedule D, with "INHERITED" listed as the acquisition date. Reporting a sale with little or no gain costs you nothing but paperwork; skipping it can trigger an IRS notice that assumes your basis was zero. A tax preparer can handle this in minutes.
Does the $250,000 home sale exclusion apply to an inherited house?
Not automatically. The federal exclusion of up to $250,000 in gain ($500,000 for couples) applies only to your primary residence — generally one you've owned and lived in for two of the last five years. If you move into the inherited house and make it your main home long enough, you can qualify later. If you're selling without living there, you rely on the stepped-up basis instead, which usually does most of the work anyway.
How do I prove the house's value on the date of death?
Order a date-of-death appraisal from a licensed appraiser — they can value the home retroactively, even a year or more later. It typically costs a few hundred dollars and becomes your documentation if the IRS ever asks how you set your stepped-up basis. Comparable sales from around the date of death or a value listed on an estate tax return can also work. Your attorney or CPA can tell you which route fits your situation.
