Selling an Inherited House in Illinois: What You Need to Know

Inheriting a house can feel like a gift and a burden at the same time. You may want to sell it quickly, but the legal process — especially if the estate goes through probate — adds steps that most people haven't dealt with before. This guide walks through what's involved in selling an inherited property in Illinois, including tax implications families often overlook.

Can You Sell an Inherited House Right Away?

It depends on how the property transferred to you.

If the house passed through a trust or joint tenancy, you may be able to sell relatively quickly. The property transfers outside of probate, so once the paperwork is in order (typically a death certificate and an affidavit), you can proceed with a sale.

If the house was titled solely in the deceased's name, it likely needs to go through probate before it can be sold. The estate must be opened with the Illinois circuit court in the county where the deceased lived, an executor appointed, and Letters of Office issued before anyone has legal authority to sell.

If the estate qualifies as a small estate (under $100,000, no real property — though this rarely applies when a house is involved), Illinois offers a simplified affidavit process that avoids full probate.

Selling Through Probate in Illinois

When probate is required, the sale process looks like this:

Step 1: Open the estate. File a petition at the local circuit court. The court appoints an executor and issues Letters of Office — the legal document that authorizes the executor to act on behalf of the estate, including listing and selling real property.

Step 2: Get an appraisal. Establish fair market value before listing. This protects the executor from claims of underselling and may be required by the court.

Step 3: List the property. The executor signs as seller on behalf of the estate. The sale proceeds like a standard real estate transaction.

Step 4: Court approval (if required). In supervised administration, the accepted offer may need court approval before closing. Independent administration — more common when heirs agree — allows the executor to close without this step.

Step 5: Distribute proceeds. After closing, sale proceeds go into the estate account to pay debts and fees before being distributed to heirs.

Inherited Property Tax in Illinois: What to Expect

This is where many families are caught off guard. Here's a plain-language breakdown:

Illinois has no inheritance tax — heirs do not pay tax simply for receiving property. However, there are other tax considerations:

Capital gains and the stepped-up basis. When you inherit a property, your cost basis for tax purposes is "stepped up" to the fair market value at the date of death — not what the original owner paid. This is one of the most favorable tax treatments in the tax code.

For example: if the deceased bought the home for $80,000 in 1985 and it's worth $350,000 at death, your basis is $350,000. If you sell it for $365,000, you only owe capital gains tax on the $15,000 gain — not on the full appreciation over decades.

If you sell quickly, you may owe little to no capital gains tax because the sale price is close to the stepped-up basis.

If you hold the property and it appreciates further before you sell, you'll owe capital gains on the amount above your stepped-up basis.

Federal estate tax only applies to estates above $13.6 million (2024 federal threshold). Most Illinois families won't encounter this.

Illinois estate tax applies to estates over $4 million. Illinois has one of the lower thresholds in the country, so larger estates in high-value areas (Chicago suburbs, Lake County, DuPage County) should be aware of this.

Splitting an Inherited House Among Multiple Heirs

When multiple heirs inherit a property together, selling becomes more complicated if they can't agree. Common situations:

One heir wants to sell; another wants to keep the property
Heirs disagree on listing price or timing
One heir is living in the home and resists selling

In most cases, if heirs can't agree, the executor has authority to proceed with a sale in the best interest of the estate. If a beneficiary is contesting the sale, the matter may need to go before the probate court.

An experienced probate attorney can help navigate family disagreements and keep the process moving.
