Form 1120-H Requirements, Deadlines, and Penalties

A homeowners association files Form 1120-H by completing the return, splitting its income between exempt member assessments and taxable non-member income, and sending it to the IRS by the 15th day of the fourth month after its tax year closes. For a calendar-year association, that means April 15. Filing the form is itself the election under Internal Revenue Code Section 528, which taxes only the non-member income at a flat 30% (32% for timeshare associations) instead of running the whole return through the standard corporate system.

Confirm the Association Qualifies

Only three kinds of organizations may use Form 1120-H: condominium management associations, residential real estate management associations, and timeshare associations. In each case, the units in the community must be substantially all residential, so a mostly commercial development is out.¹

Beyond that, Section 528 sets four tests. Miss any one of them in a given year and the association must file a regular corporate return on Form 1120 instead.²

Organizational Purpose

The association must be organized and operated to acquire, build, manage, maintain, and care for community property. The declaration of covenants, conditions, and restrictions usually settles this. If the governing documents describe the association’s purpose as maintaining common areas and shared infrastructure, the test is met.²

The 60% Income Test

At least 60% of gross income for the year has to come from exempt function income: membership dues, fees, and assessments paid by owner-members in their capacity as owners. The label doesn’t matter; the source does.³

Everything else counts as non-exempt. Interest on reserve accounts, antenna or cell tower lease payments, and fees charged to outsiders for renting common facilities are the usual examples, and together they must stay within the remaining 40%.¹

The 90% Expenditure Test

At least 90% of total spending must go toward acquiring, building, managing, maintaining, and caring for community property. Landscaping, insurance on common areas, common-area utilities, and capital reserve contributions all count. Costs tied to non-exempt activities (like running a rental program for outsiders) do not.²

No Private Benefit

No part of net earnings may benefit a private individual or shareholder, other than through the association’s normal maintenance activities or through rebates of excess dues to members. Diverting profits to a board member or the developer breaks this test.²

How the Tax Is Figured on the Return

The point of Form 1120-H is the income split. Exempt function income (dues, fees, and assessments from owner-members) drops out of the tax calculation entirely. Tax is owed only on non-exempt function income.²

Non-exempt income typically includes interest on bank accounts and reserve funds, rental income from non-members using common facilities, vending machine revenue, and cell tower or antenna lease payments. Start with gross non-exempt income, subtract expenses directly connected to producing it (for a clubhouse rented to outsiders, that means the cleaning and staffing costs of those rentals), then subtract a fixed $100 specific deduction. What’s left is taxable income.¹

Condominium and residential real estate management associations pay a flat 30%. Timeshare associations pay 32%. Both rates apply to ordinary income and capital gains alike, with no preferential rate for long-term gains.² These rates are set by statute and don’t move with the standard corporate rate, so treating the 21% corporate rate as the number to plan around is one of the most common mistakes on this return.

A few restrictions come with the election. Net operating loss deductions under Section 172 are not allowed on Form 1120-H, and neither are the special corporate deductions like the dividends received deduction.¹

What to Pull Together Before Filling Out the Form

Getting the numbers organized before opening the form prevents errors that can trigger IRS notices or, worse, make it impossible to check the qualification-test boxes honestly.

The association’s Employer Identification Number and the start and end dates of its fiscal year.
Every dollar of gross income sorted into exempt function income or non-exempt function income. This separation populates the income lines and documents compliance with the 60% test.
Every expense sorted into community-property spending (which supports the 90% test) and non-exempt spending (which becomes deductions against non-exempt income).
Categorized totals tied back to the association’s bank statements, general ledger, and year-end financial reports.

Items A through D on the return require the association to check boxes confirming it meets each Section 528 test. Bookkeeping that blurs exempt and non-exempt categories makes those confirmations impossible to sign off on with a straight face.

When and Where to File

The return is due on the 15th day of the fourth month after the association’s tax year ends, which is April 15 for calendar-year associations.¹

If more time is needed, filing Form 7004 gets an automatic six-month extension, pushing the deadline to October 15 for calendar-year filers. The extension covers the paperwork only, not the payment. Interest runs on any unpaid tax from the original due date regardless. To avoid the late-payment penalty on extension, pay at least 90% of the tax ultimately shown on the return by the original due date and settle the balance by the extended date.⁴

Paper returns go to one of two IRS service centers depending on where the association is located. The current addresses (Kansas City, MO 64999-0012 for one group of states, Ogden, UT 84201-0012 for the rest) are listed on the IRS’s Form 1120-H filing address page.⁵ Electronic filing through an authorized IRS e-file provider is faster and gives immediate confirmation of receipt.

One procedural point that eases the workload: an association that elects Form 1120-H is not required to make quarterly estimated tax payments. A Form 1120 filer may owe estimated installments through the year.¹

Whether Form 1120-H Is the Right Choice This Year

The election is made fresh each year by filing the form, and it generally has to be filed by the return’s due date, including extensions. Once made for a year, it can’t be revoked without IRS consent.¹

Annual flexibility matters because Form 1120-H isn’t always the cheaper option. Its 30% flat rate on non-exempt income sits above the 21% standard corporate rate on Form 1120. In a year with substantial non-member income, the math can favor the regular corporate return. For most associations, though, non-member income is modest and Form 1120-H shields all of the exempt function income from tax entirely, so the savings on the exempt side outrun the higher rate on the taxable side.

Penalties for Filing or Paying Late

Missing the deadline costs more than just the ability to elect Section 528 treatment for that year. The IRS charges separate penalties for filing late and paying late, and they stack.

Late filing: 5% of the unpaid tax for each month or partial month the return is overdue, capped at 25%.
Minimum late filing penalty: if the return is more than 60 days late, the minimum for returns due in 2026 is the lesser of the tax owed or $525.
Late payment: 0.5% of the unpaid tax for each month or partial month it remains unpaid, capped at 25%.

Interest also runs on any unpaid balance. The underpayment interest rate for 2026 is 7% per year, compounded daily, from the original due date until paid.⁶

The late filing penalty can be waived for reasonable cause, but the IRS applies a high bar; a treasurer transition or a simple oversight generally won’t clear it. Many states also impose their own penalties and minimum taxes, so the federal figures are often not the whole bill.

Keeping the Records After Filing

The IRS expects the association to hold every document supporting the income, deductions, and qualification-test math on the return. The general rule is three years from the date the return was filed or two years from the date the tax was paid, whichever is later.⁷

Longer periods apply in certain situations. If the association underreports income by more than 25% of what it shows on the return, the audit window stretches to six years. If no return is filed, or a fraudulent one is filed, there is no time limit. Board turnover being what it is in community associations, six years of records kept somewhere the current treasurer can actually find them is the practical standard.⁷
