Taxes on Selling a House in Illinois: What to Expect

Capital gains tax

Matichyn says it’s important to plan ahead and know what to expect before you list your home for sale. She cautions that there’s one big tax that can catch homeowners by surprise if they’ve only lived in a home for a short time.

“Capital gains tax, especially if you lived in the home for two years or less, can be a hefty tax that you may have to pay,” Matichyn says.

If you profit from the sale of a home in Illinois, then you may owe some capital gains tax unless you qualify for an exclusion, which we’ll address in the table below.

Capital gains are the profits made when you sell an appreciable asset, such as your home. For example, if you buy a home for $270,000 and sell it for $370,000, you have a capital gain of $100,000.

Capital gains are taxed by both the state and federal governments, but Illinois does not distinguish between short-term and long-term capital gains. It taxes all capital gains as ordinary income. In this case, without a qualifying exemption, you’ll pay the state’s flat income tax rate of 4.95%, regardless of your income level.

However, on the federal level, gains can be considered either short-term or long-term.

Capital gains tax exclusion

Both the IRS and the state of Illinois provide a capital gains tax break for home sellers who meet certain conditions.

“If you lived in the home for at least two out of the last five years before the sale, you may qualify for exclusion up to $250,000 of the gain for a single taxpayer and $500,000 for a married couple who are filing jointly,” Matichyn explains.

This is a statutory exclusion on profits from the sale of your family home. To qualify for the full exclusion amount, according to IRS Publication 523, the following criteria must be met:

• You’re selling your primary residence.
• You’ve owned the home for at least two years in the five-year period before selling it.
• You’ve lived in the home for at least two years within the five-year period before selling it. The years you’ve lived in it don’t need to be consecutive. Certain exceptions to this rule are made for those who are disabled or those in the military, Foreign Service, intelligence community, or Peace Corps.
• You didn’t acquire the home through a like-kind exchange, also known as a section 1031 exchange, within the past five years. This is basically when you swap one investment property for another.
• You haven’t claimed the exclusion on another home in the past two years.
• You aren’t subject to expatriate tax, a government fee paid by those who renounce their citizenship or take up residency in another country.

As a seller, if your property or circumstances don’t check all of the IRS exemption boxes, you may still qualify for a partial exclusion of gain. This can happen if the main reason for your home sale is a change in job location, a medical health issue, or an unforeseeable life event. For details on such circumstances, refer to IRS Publication 523.

If you’re going to be in a position to make a substantial profit, Matichyn recommends that you talk to a tax professional before we put your home on the market. “You’ll want to discuss this with your CPA. Find out what the tax will be, or what the amount or percentage you’ll have to pay, and if there are ways to reduce your costs.”

How to report your Illinois capital gains taxes

For your federal return, report your capital gains and losses by using U.S. Individual Income Tax Return (IRS Form 1040) and Capital Gains and Losses, Schedule D (IRS Form 1040). You can report your Illinois capital gains or losses on Illinois Form 1040.

Transfer tax

Illinois home sellers pay a transfer tax, which is a fee imposed by the state (and sometimes local governments) whenever a property changes ownership. It’s usually calculated as a percentage of the home’s sale price and is collected at closing to help fund government programs.

The state-mandated transfer tax is 50 cents per $500 of the sale price (or ​​one dollar for every thousand dollars). In addition, counties can impose an additional tax of 25 cents per $500 (or ​​50 cents for every thousand dollars).

For example, if you sell a home in Palatine for $300,000, you’ll pay $300 to the state of Illinois and $150 to Cook County. Currently, all Illinois counties, including Cook, DuPage, Kane, Lake, McHenry, and Will, charge 25 cents per $500 of the home’s purchase price. Home rule municipalities may also impose an additional real estate transfer tax.

Property tax

In Illinois, the effective property tax on a home you live in is about 1.83% of its value. On an average $270,000 home, that comes out to roughly $4,940 a year. However, what you’ll pay exactly in property tax will vary by country.

“In Illinois, we pay property taxes a year behind,” Matichyn explains. “So a seller would have to give a credit to the buyers for the current year of them owning the home when the tax bill comes out.”

She adds that tax bills are sent out at different times of the year, depending on the county. “So if we’re closing on a home in September, the seller would have to give nine months’ worth of tax proration to the new buyer so [that] they can pay for the taxes whenever the tax bill comes out next year.”

Median property tax estimates by county

Here’s the annual median property tax you might expect to pay in Illinois’s seven largest counties:

• Cook County: $6,053
• DuPage County: $7,833
• Lake County: $8,743
• Will County: $6,993
• Kane County: $7,230
• McHenry County: $7,153
• Winnebago County: $3,850

In some smaller areas, the median property tax cost estimates are much less, such as Williamson County ($2,490) and Pope County ($1,687).

Matichyn says there are property tax exemptions, such as Cook County’s Homeowner Exemption, that can assist some property owners. “This is something that you can apply for when you’re looking to buy your primary residence.

“If you’re buying a home from an owner who has the home as a primary residence, a lot of times, you don’t have to apply. It just transfers over to you. It’s a good discount that every homeowner gets just by living in their home.”

She says there are additional tax incentives to seniors and veterans, which can also help lower taxes. “There are a lot of different ways to save on taxes. It just obviously depends on the specific situation and the county you are in. But if you’re buying an investment property, those incentives typically go away.”

A house-selling tax mistake to avoid in Illinois

Matichyn says one of the biggest mistakes she sees comes from homeowners who never research or question their property tax bills.

“I’ve seen quite a few properties where the taxes were high compared to what other homeowners pay in the area. The home is very similar — the square footage, all built around the same time — but one specific property will have really high taxes, which makes it harder for them to sell the house.”

She shares a situation where it turned out the seller’s home was being taxed unfairly.

“I had a home in [the] Northwest Suburbs priced at $600,000, and the taxes were $20,000, which is way too high for that specific area. (Everybody else in the area had like $14,000.) The county had the square footage wrong. The home had vaulted ceilings, and the county counted it as if there was a roof or a second floor above the first floor, like a family room, when, in fact, it was just air. The owners never looked into that, and they just kept paying the taxes.”

Matichyn adds, “This is public record — you can look up what your neighbors are paying in taxes, and if you feel like your bill is quite high or higher than it should be, you can always appeal your taxes.”

Inheritance tax

Illinois is one of only a few states in the U.S. that still imposes an estate tax when someone dies. How much you’ll pay depends on the value of the property. The good news is that it’s only applied to estates worth more than $4 million.

When selling an inherited home, many of the same considerations apply as they do to selling any Illinois property, including property taxes. Where things differ is with capital gains.

Fortunately for heirs, the values of inherited assets are adjusted by what’s called a step-up in basis. This means that no matter how much an Illinois home has appreciated in value since it was originally purchased, a decedent’s heirs are not responsible for paying the taxes on those historical gains if they choose to sell the home. Rather, the property automatically converts to the current market value.

If an heir decides to sell the property right away for the assessed market value, then there are typically no gains. However, if an heir sells the property for more than the fair market value or chooses to hold onto the house for a while before selling, and its value continues to appreciate during that time, then those are usually considered taxable gains.

Other selling expenses to anticipate in Illinois

• Title fees: These consist of title insurance and a title search. Title insurance is designed to protect both the lender and the buyer of property against any issues with a home’s title, such as forgeries, an undiscovered will, or deed restrictions, that could arise during a title search. Who pays the title insurance can vary by state. In Illinois, this typically falls to the seller.
• Settlement fees: These fees typically amount to about 1% of the home sale. This lump sum (often referred to as escrow fees) is issued by the title company, escrow company, or attorney facilitating the transaction’s closing.
• Agent commissions: Agent commission fees in Illinois are typically around 5.8%, and the buyer’s agent and seller’s agent split the commission. The seller typically pays for both agents’ commissions, but a landmark settlement by the National Association of Realtors (NAR) shifted the rules, giving buyers more control to negotiate agent fees directly. Now, buyers can work with their agents to decide exactly what they’ll pay, but sellers are still responsible for covering their listing agent’s commission. 

Smart home prep to beat tax

Preparing your home before listing can have a direct impact on buyer interest and final sale price. Small improvements and thoughtful presentation often help a property stand out in competitive markets.

Matichyn advises, “The best advice would be to make sure the home is prepared. Even though it is a seller’s market, it doesn’t mean that houses sell themselves. Even if it’s [in] a great area and [has] very desirable schools and a price range, the better the home shows, the more money the buyer is willing to pay for it.”

To get the highest price for your home, Matichyn says the preparations don’t need to be extreme. “We’re not talking about investing tens of thousands of dollars. Sometimes a deep clean would do, or having a Realtor come through and give you a stage-in recommendation, what to donate, what to keep in the house, what to pack up, how to make sure the home shows bigger, brighter, and more updated.”

In closing, Matichyn says she tells her clients to put themselves in the buyers’ shoes. “Are there some small things you could do to make the home feel more updated and move-in ready? Buyers will pay extra for the ability to move in and not do anything.”
