The Top Illinois Rental Property Tax Deductions to Know

Many investors in Illinois leave money on the table each year simply because they aren’t aware of the deductions available to them.

Maybe you’re worried about making a mistake with the IRS and end up overlooking deductions you could legally claim. Or perhaps you’re so focused on your rental income that you don’t realize how much your expenses, from repairs to property taxes, can actually work in your favor at tax time.

In this post, we’ll break down the essential rules, highlight often-overlooked deductions, and share practical tips to help Illinois property owners mitigate taxes and keep more of your hard-earned income.

Illinois rental property tax deduction rules

Before you start adding up receipts and filling out forms, it’s important to know that most rental property tax deductions are governed by federal law. However, Illinois does have a few state-specific rules and modifications that every landlord should understand, especially if you want to avoid surprises at tax time.

What Illinois does not allow: the property tax credit exclusion

Let’s start with one of the most common misconceptions. Illinois offers a property tax credit for homeowners, but this credit is not available for rental properties. If you own a single-family rental or a condo you lease to tenants, you cannot claim the Illinois Property Tax Credit on your state return.

This credit is only for homeowners who live in their property as their main residence. It’s not available for rental properties, vacation homes, vacant lots, farm land, or properties outside Illinois. So, while you may have heard about the 5% property tax credit, it doesn’t apply to your rental.

The good news is you can still deduct property taxes on your federal tax return as a business expense, and this deduction flows through to reduce your Illinois taxable income as well.

Property tax business deduction (not subject to SALT cap)

Here’s another silver lining: Illinois landlords can fully deduct property taxes paid on rental properties as a business expense on your federal return (Schedule E).

Unlike property taxes on your personal residence, property taxes for an investment property are not subject to the $10,000 state and local tax (SALT) deduction cap.

Keep in mind, if you have a mixed-use property (part rental, part personal), only the rental portion is exempt from the SALT cap. Personal-use portions are still subject to the limit.

Illinois depreciation rules: bonus depreciation add-back

If you’re making improvements to your rental and claiming bonus depreciation on your federal return, Illinois requires you to “add back” that bonus depreciation when calculating your state taxable income. This is because the extra depreciation you claim federally typically doesn’t reduce your Illinois tax bill in the same year. You may need to report this on Illinois Form IL-4562.

As a result, you may owe more Illinois state tax in the year you claim bonus depreciation federally. However, Illinois does typically allow you to subtract this amount in future years, either when you sell the property or when you finish claiming federal depreciation. This creates a timing difference, not a permanent loss of the deduction.

For property placed in service after December 31, 2024, and before January 1, 2026, you are generally required to add back 40% of the bonus depreciation claimed federally on your Illinois return. Planning ahead can help you avoid surprises. For more details, see the Illinois Department of Revenue’s official instructions for Form IL-4562.

Affordable housing special assessment program

Although this program is designed for properties with 7 or more units, it’s still helpful to be aware of Illinois’s Affordable Housing Special Assessment Program (especially if you’re considering expanding your rental portfolio in the future).

This program can lower the assessed value of your property if you own a qualifying building and meet the program’s affordability and investment requirements. A lower assessed value means you’ll pay less in property taxes each year, which can directly boost your cash flow.

Short-term rental tax rules

If you rent out your property for short-term stays (less than 30 days at a time), Illinois imposes specific taxes, including a state tax rate, occupancy tax, and hotel operators’ occupation tax.

These are typically collected automatically by platforms like Airbnb, but it’s important to keep good records and understand your obligations. The federal “14-day rule” still applies: if you rent your property for 14 days or less per year, that income isn’t taxable, but documentation is key.

New for 2025: sales tax on leased personal property

Starting January 1, 2025, Illinois began imposing sales and use tax on payments for the lease of tangible personal property. This primarily affects landlords who lease furniture, appliances, or other tangible items along with their rental property.

If you provide these extras, you’ll need to register with the Illinois Department of Revenue and pay sales tax on those lease receipts. This is a new requirement, so keep it on your radar if it applies to your rental business. You can read the Illinois Department of Revenue bulletin here.

Other rental property tax deductions in Illinois

In addition to the state-specific rules we’ve covered, Illinois landlords can take advantage of a wide range of deductible expenses on their federal and state tax returns. These deductions are reported on Schedule E and can make a significant difference in your bottom line.

Here are some of the most common (and sometimes overlooked) deductions you may be able to claim:
