association qualifies to file, but they are not taxed. This treatment reflects the fact that assessments are collected for the mutual benefit of members, not as revenue in the corporate sense.
Non-exempt income includes revenue from sources that are not derived from membership obligations. This typically consists of interest earned on bank or investment accounts, rental income, fees received from non-owners, vending machine or laundry revenue, and telecom or rooftop lease payments. This type of income is taxed at a flat 30 percent rate. Although the rate is higher than the corporate rate under Form 1120, the amount of revenue subject to the tax is usually smaller because associations generally do not derive significant income from non- member sources.
A critical point of confusion for many boards involves the deduction of expenses. The financial statements of an association list its operating costs, including maintenance, landscaping, utilities, management fees, administrative expenses, and reserve funding. These expenses are legitimate operating costs, but under Form 1120H they do not reduce taxable income unless they are directly connected to producing non-exempt income. This distinction is essential because it prevents associations from applying broad operating costs to offset the limited revenue that is taxable.

To determine which expenses qualify as deductions, associations must evaluate the specific activities generating non-exempt income. If the association earns rental income from a clubhouse, the costs directly tied to rentals, such as cleaning, supervision, or administrative oversight of rentals, may be allocated. If it earns income from a cell tower lease, only the portion of legal review, structural analysis, or insurance costs that relate directly to the leased area can be deducted. If the association earns interest income, bank charges or advisory fees that pertain to the investment accounts may be deducted. Each allocation must be reasonable, supported by documentation, and connected specifically to the taxable revenue.
Mixed use situations require additional care. When amenities such as clubhouses, marinas, or recreational areas are used for both exempt and non-exempt purposes, expenses must be allocated based on measurable criteria. Time of use, number of taxable events, or similar metrics may be used, provided they reflect actual usage and are applied consistently. The IRS expects associations to justify their allocation methods, and accurate records protect the association if the return is ever questioned.
While Form 1120H provides clarity and protection, some associations consider filing Form 1120, the standard corporate tax return. The attraction is usually the lower tax rate and the broader range of deductible expenses. Under the corporate tax structure, many expenses that

cannot offset taxable income under Form 1120H could reduce taxable income under Form 1120. At first glance, this can appear beneficial, particularly in years when non- exempt income is higher or when expenses directly relate to generating that income.
critical point of confusion for many boards
The risks associated with filing Form 1120, however, are substantial. The most significant risk involves reserve funds. Under Form 1120H, contributions to reserves are treated as exempt function income and are not taxed. Under Form 1120, the IRS may treat these contributions as taxable revenue unless the association can prove that they qualify as capital contributions. This is a high standard. If reserve contributions are reclassified as taxable income, the association may face a large and unexpected tax bill. Because reserve contributions often represent a significant portion of the budget, this risk alone is enough to make Form 1120 a dangerous choice.
Beyond reserve funds, filing Form 1120 increases the likelihood that regular assessments, special assessments, fines, and owner charges will be treated as taxable corporate income. Under corporate tax principles, a community association must provide strong justification for treating these payments as nontaxable. Failure to provide adequate documentation may result in the IRS treating nearly all association revenue as taxable income. Additionally, Form 1120 is more complex, subject to stricter accounting rules, and more likely to draw scrutiny because it is designed for profit driven corporations, not for community associations.
By contrast, Form 1120H offers a predictable and protective tax structure. It aligns with the unique nature of association revenue, shields assessment and reserve income from taxation, and limits the association’s tax exposure to the relatively small amount of income that arises from non- member sources. This makes it the most practical and responsible filing choice for most associations.
Community associations are charged with maintaining common property, preserving the value of their communities, and managing large amounts of member funded assets. Their tax compliance decisions should support these goals. Understanding Form 1120H and the risks associated with Form 1120 allows boards to make informed decisions that protect the financial well- being of their associations. In nearly all cases, electing Form 1120H each year remains the soundest approach for ensuring that assessments and reserves remain available for their intended purpose.
