1031 Exchange in Illinois

Illinois follows federal 1031 exchange rules and has a flat state income tax rate of 4.95%. The state does not impose withholding on non-resident sellers of real estate and has no clawback rule for gain deferred into out-of-state property. Investors should factor in Illinois's real estate transfer taxes (state, county, and in some municipalities local) and property tax rates that are among the highest in the nation when evaluating replacement properties.

Fast Facts

State Income Tax on Capital Gains
4.95% (flat rate). Illinois taxes capital gains as ordinary income at its flat 4.95% individual income tax rate, which can be deferred through a qualifying 1031 exchange.
Conforms to Federal 1031
Yes. Illinois starts from federal adjusted gross income and makes no modification for Section 1031 gain, so an exchange that is valid at the federal level defers Illinois income tax as well.
Non-Resident Withholding
None. Illinois does not impose income tax withholding at closing on non-residents selling real property, making the process simpler for out-of-state investors.
Real Estate Transfer Tax
$0.50 per $500 of value (state), plus $0.25 per $500 (county) and additional local transfer taxes in some municipalities. Transfer taxes apply to 1031 exchange transactions like any other sale.
Property Tax Rates
Varies by county; Illinois's average effective property tax rate is roughly 2%, second-highest in the nation per the Tax Foundation, with significant variation by county and municipality.


Step-by-Step Process

  1. 1

    Identify Replacement Property

    You must identify potential replacement properties within 45 days of selling your relinquished property. In Illinois, consider property tax variations by county and local transfer taxes when identifying properties.

  2. 2

    Engage a Qualified Intermediary

    Work with a qualified intermediary to handle the exchange funds and documentation before closing on the sale of your relinquished property. Illinois does not impose a state licensing or registration regime specific to exchange facilitators, so vet your QI's bonding, insurance, and track record carefully.

  3. 3

    Close on Replacement Property

    Complete the purchase of your replacement property within 180 days of selling your relinquished property. Be aware of Illinois's real estate transfer taxes (state, county, and any municipal), which will apply to the transaction.

  4. 4

    File Tax Returns

    Report your 1031 exchange on your federal tax return using Form 8824 and on your Illinois state tax return. Non-residents should file Illinois Schedule NR to report Illinois-source income.

  5. 5

    Property Tax Considerations

    Illinois has some of the highest property tax rates in the nation — a roughly 2% average effective rate per the Tax Foundation — with significant variation by county and municipality. When selecting replacement properties, research local property tax rates and reassessment history (Cook County reassesses on a triennial cycle), as these can significantly impact your returns.

  6. 6

    Local Transfer Taxes

    In addition to the state transfer tax of $0.50 per $500 of value and the county tax of $0.25 per $500, some Illinois municipalities impose additional transfer taxes. Chicago's combined municipal rate is $5.25 per $500 of value ($3.75 per $500 paid by the buyer plus a $1.50 per $500 CTA portion paid by the seller). Factor these costs into your exchange calculations.

Common Pitfalls

Underestimating property tax impact

Issue

Illinois has some of the highest property tax rates in the nation, which can significantly impact investment returns if not properly factored into financial projections.

Prevention

Research property tax rates in specific counties and municipalities before identifying replacement properties. Review historical reassessment patterns, particularly in Cook County with its triennial reassessment cycle. Consider budgeting for potential increases in property taxes when calculating projected returns.

Overlooking local transfer taxes

Issue

In addition to the state and county transfer taxes, some Illinois municipalities impose additional transfer taxes that can significantly increase transaction costs.

Prevention

Research local transfer tax rates in the specific municipality where you're considering purchasing replacement property. For example, Chicago's combined municipal rate of $5.25 per $500 of value is much higher than the state rate of $0.50 per $500. Factor these costs into your exchange calculations.

Ignoring local landlord-tenant regulations

Issue

Chicago has specific landlord-tenant ordinances that impose additional requirements beyond state law, which can impact property management and returns.

Prevention

If investing in Chicago residential property, familiarize yourself with the Residential Landlord and Tenant Ordinance (RLTO) and its requirements regarding security deposits, disclosures, and maintenance. Consider consulting with a property management company experienced with Chicago's regulations.
