Tax season brings specific responsibilities for condo board members managing condo association taxes in Illinois. Unlike individual tax filers, condominium associations are treated as corporate entities by the IRS, which means they face annual filing requirements even when the association owes no money.
Do Condo Associations in Illinois Have to File Taxes?
Yes. This is one of the most common misconceptions among condo board members.
Many boards assume that because their association is a not-for-profit organization, it is automatically tax-exempt. That is not the case. Being a nonprofit does not mean tax-exempt. The IRS does not grant automatic tax-exempt status to condominium associations; filing a return is required every year, regardless of whether taxes are owed.
This makes condo association taxes in Illinois similar to corporate tax obligations, requiring annual filings with both the federal and state governments.
Federal Filing: Form 1120-H vs. Form 1120
At the federal level, condominium associations generally have two options for filing.
Form 1120-H is the most common choice. It is designed specifically for homeowners’ associations and condominium associations and offers several practical advantages. According to the IRS Instructions for Form 1120-H, this form allows qualifying associations to exclude exempt function income from gross income, which typically means assessment income from unit owners is not subject to tax.
To qualify to file Form 1120-H, the association must meet a few key thresholds:
- At least 60% of gross income must come from exempt function income (dues, fees, and assessments)
- At least 90% of expenses must go toward managing, maintaining, or caring for association property
- No private individual may profit from the association’s net earnings
For associations that do owe federal tax on non-exempt income, Form 1120-H taxes that income at a flat rate of 30% for condominium management associations.
Form 1120 is the standard corporate tax return. Some associations may find it results in a lower tax liability, but it carries added complexity. Under Form 1120, any surplus income, including reserve fund contributions, may become taxable. Boards should consult a qualified CPA to determine which form is the better fit for a given year.
Illinois State Filing: Form IL-1120
For boards managing condo association taxes in Illinois, there is an additional state-level step beyond federal filing.
If a condo association files a federal Form 1120-H and has taxable income, it is also required to file Form IL-1120 with the Illinois Department of Revenue. The state return corresponds directly to the federal return, using the taxable income reported on Form 1120-H as the starting point for the Illinois calculation.
Associations with no federal taxable income may not owe state income tax, but it is important to confirm this with an accountant who is familiar with Illinois association law each year.
What Counts as Taxable Income for Condo Associations in Illinois?
Understanding what is and is not taxable is one of the most important parts of managing condo association taxes in Illinois.
Exempt function income is generally not taxable. This includes:
- Monthly or annual assessments from unit owners
- Special assessments collected for common area maintenance
- Membership fees and dues
Non-exempt income may be subject to tax. Common examples include:
- Interest earned on reserve funds or operating accounts
- Income from laundry machines or vending equipment
- Facility rental income from non-members
- Investment income or dividends
Even small amounts of non-exempt income can create a tax liability. Tracking this income carefully throughout the year makes the filing process more accurate and straightforward.
Property Taxes on Common Areas in Illinois
Beyond income taxes, Illinois condo associations also face property tax considerations for their common areas.
As noted by KSN Law, a firm that works with community associations throughout Illinois, the Illinois Revenue Act provides that common areas used by unit owners are assessed for property taxes at no more than $1.00 per year. This applies to hallways, lobbies, parking garages, clubhouses, and similar shared spaces.
Board members who receive a common-area property tax bill should verify that the assessed value is $1.00 or less. If it does not, the association should file an appeal with the county tax assessor promptly to correct the assessment.
Vendor Payments and Form 1099 Requirements
Condo associations have separate reporting responsibilities for vendor payments.
Any vendor or independent contractor paid $600 or more during the tax year must receive a Form 1099-NEC from the association. This includes landscaping companies, snow removal contractors, maintenance technicians, and other service providers operating as sole proprietors or partnerships.
To meet this requirement, associations should collect W-9 forms from all vendors before work begins. Waiting until tax season to gather this information creates unnecessary delays and the risk of missing deadlines.
Key Tax Deadlines for Illinois Condo Associations
Tax deadlines for condo associations align with the corporate calendar, not the individual tax calendar.
For associations on a calendar year (January through December), the federal and state returns are due by April 15. If the association needs more time, it can request an automatic extension using Form 7004. This extends the filing deadline but does not extend the time to pay any taxes owed.
Associations operating on a fiscal year that ends on a date other than December 31 should note that the return is typically due 3.5 months after the fiscal year-end.
Common Tax Mistakes Illinois Condo Boards Make
Even well-organized boards can run into issues when handling condo association taxes in Illinois. The most frequent mistakes include:
- Assuming no filing is required because the association is a nonprofit
- Failing to track non-exempt income, such as interest, throughout the year
- Missing vendor 1099 deadlines due to incomplete W-9 records
- Not verifying the common area property tax assessment each year
- Waiting until the last minute to engage a CPA, leaving little time to address questions or gather documentation
Addressing these issues before tax season reduces the likelihood of errors and penalties.
How Association Management Supports Financial Compliance
Managing tax obligations is one reason many Chicago condo associations choose to work with a professional association management company.
A management partner can work alongside the association’s CPA and legal counsel to help keep financial records organized throughout the year. This may include coordinating vendor documentation, supporting accurate reporting, and providing the financial records an accountant needs to prepare the association’s returns. Year-round record-keeping reduces the administrative burden on board members and helps the association stay prepared well before filing deadlines arrive.
Boards exploring this option may also find it helpful to review how to choose the right association management company for a Chicago condo to understand what to look for in a management partner.
Sound financial management also extends to other areas of association planning. Boards focused on keeping costs predictable may find that reading about why multi-year vendor contracts can save condo boards money offers useful context, as contract structure directly affects the financial records that support accurate tax filings.
Tax Season Prep Checklist for Condo Boards
When preparing for condo association taxes in Illinois, boards can take several steps well ahead of the filing deadline to make the process smoother:
- Confirm the association’s fiscal year-end date and corresponding filing deadline
- Gather year-end financial statements and bank records
- Identify and total all non-exempt income earned during the year
- Confirm all vendor W-9 forms are on file and 1099s are issued by January 31
- Verify the common area property tax bill reflects an assessment of $1.00 or less
- Engage a CPA with experience in Illinois condo association taxes
- Review the prior year’s return for carryover items or outstanding issues
Starting this process in the fourth quarter, rather than waiting until April, gives boards and their advisors the time needed to file accurately and on time.
Working With the Right Professionals
Condo association taxes in Illinois involve both federal and state requirements, and the rules can be nuanced. A CPA who regularly works with condominium associations understands the specific provisions that apply, from Form 1120-H qualification thresholds to Illinois common area property tax rules.
Boards that want to reduce the time they spend on financial administration may also benefit from partnering with a management company that supports organized, year-round record-keeping. To learn more about what that kind of support looks like, request a proposal from Hales Property Management.
