Are Co-op Fees Tax Deductible? Maintenance, Interest, and Limits

Co-op fees are partially tax deductible, but only the slice of each monthly maintenance payment that covers the building’s property taxes and its mortgage interest. Everything else the fee pays for — staff wages, insurance, utilities, repairs, landscaping — is a personal living expense with no federal tax benefit. Because a cooperative corporation owns the building and you own shares in it, federal law lets you claim your proportionate share of those two expenses as if you paid them yourself.

What Part of the Maintenance Fee Is Deductible

You don’t directly own your unit in a co-op. You own shares in a corporation that owns the building, and that corporation pays the property taxes and services its own mortgage. Under federal law, you’re treated as though you personally paid your proportionate share of those two expenses.¹ The pass-through covers property taxes and interest on debt the corporation took on to buy, build, or maintain the building.²

Your share is set by how many shares you own relative to the total. If you own 500 shares in a building with 10,000 total shares, you claim 5% of the building’s deductible taxes and interest. The math is done for you: cooperatives are required to file Form 1098 reporting each shareholder’s share of interest when it exceeds $600 for the year.³ Property tax information typically appears in Box 10 of that same form or in a separate year-end letter from the managing agent. Keep every annual statement; these are what you’d produce if the IRS ever questions your return.

Both deductions require you to itemize on Schedule A rather than take the standard deduction, so whether they actually save you money depends on the limits described further down.

What You Cannot Deduct

The bulk of most maintenance fees covers operating costs that carry no tax benefit. Building staff salaries, lobby maintenance, hallway utilities, elevator service contracts, the corporation’s insurance premiums, landscaping — all of it counts as personal living expense in the eyes of the IRS.⁴ The same applies to service charges like water usage fees and trash collection, even when they show up on a government bill.

This catches some shareholders off guard. A $2,500 monthly maintenance fee sounds like a large annual deduction, but if only $800 of it covers property taxes and building mortgage interest, the deductible portion is $800. The remaining $1,700 is no different, tax-wise, from paying rent. Claiming the full maintenance amount is one of the more common Schedule A errors and it invites audit attention.

Interest on Your Personal Co-op Loan

The building’s mortgage pass-through is only half the picture for most owners. If you took out a loan to buy your shares, the IRS treats a cooperative apartment as a qualified home, and interest on that loan is deductible as home mortgage interest, subject to the same limits that apply to any residential mortgage.⁵ Your share of the cooperative’s own debt also counts toward those limits, so the co-op should tell you how much of its debt is allocated to your shares.

Points paid when you took out the share loan may also be deductible. Points on a loan for your main home can generally be deducted in full the year you paid them, provided you meet the IRS requirements, including that the loan is secured by your primary residence and the points aren’t unusually high for your area.⁵ For a second home, or if you don’t meet the full-deduction tests, points are spread evenly over the life of the loan.

Limits That Shrink the Benefit in Practice

Three federal limits can reduce or wipe out the tax benefit of your co-op deductions.

The SALT Cap

Your share of the building’s property taxes counts as a state and local tax deduction, which is subject to the federal SALT cap. For 2026, the cap is $40,400 for most filers and $20,200 if married filing separately, under the One Big Beautiful Bill Act. State income tax competes for the same cap. Once your combined state income tax and property tax deductions hit $40,400, additional property tax passed through by the co-op produces no further benefit. The cap phases down for taxpayers with modified adjusted gross income above $505,000 and eventually reaches a floor of $10,000.

Mortgage interest is not affected by the SALT cap. Interest and taxes are separate line items on Schedule A.

The Standard Deduction Threshold

None of these itemized deductions matter unless their total exceeds the standard deduction. For 2026, that’s $16,100 for single filers and $32,200 for married couples filing jointly.⁶ A married couple in a co-op with relatively low property taxes and a small building mortgage may find their pass-through deductions fall well short of $32,200, especially without other significant itemizable expenses. In that case, the deductions exist on paper but produce zero tax savings. Owners who also carry a personal share loan with meaningful interest payments are more likely to clear the standard deduction hurdle.

The Alternative Minimum Tax

Taxpayers subject to the AMT face an added wrinkle: state and local tax deductions, including your share of the building’s property taxes, get added back to income when calculating AMT liability.⁷ Mortgage interest generally remains deductible under the AMT, but the property tax pass-through effectively disappears. If you’re in AMT territory, your co-op tax deduction may be worth less than it looks on Schedule A.

Business or Rental Use of Your Unit

The nondeductible operating portion of your maintenance fee can become partially deductible if you use the apartment for business or rental income.

Home Office

If you use part of your apartment exclusively and regularly as your principal place of business, you can deduct a proportionate share of the entire maintenance fee, including the operating costs that are otherwise nondeductible. The business percentage is usually calculated by dividing the office square footage by the total apartment square footage.⁸ A 200-square-foot office in a 1,000-square-foot apartment means 20% of your maintenance fee, utilities, and similar costs become a Schedule C business expense.

The IRS is strict about exclusive use. A desk in your living room where you also watch television does not qualify. The space must be used only for business, though it doesn’t need to be a separate room with a door.

Renting the Unit Out

When you rent out your co-op unit, assuming the building allows it, the full maintenance fee becomes a deductible expense against rental income on Schedule E.⁸ That’s a meaningful shift from personal-use treatment, where most of the fee is off the table.

Depreciation

Shareholders using their unit for business or rental purposes can also claim depreciation on the portion of their stock allocable to that use. Federal law explicitly treats co-op stock used in a trade or business as depreciable property.¹ The recovery period is 27.5 years, the same as any other residential rental property.⁹ One limit: the depreciation deduction for any year can’t exceed your adjusted basis in the stock, so keep that figure current.

Special Assessments Are Not Deductible, But They Still Matter

When the board levies a special assessment for a major project like a new roof, boiler replacement, or facade restoration, that payment is not deductible in the year you pay it. Instead, you add the amount to your cost basis in your shares.¹⁰ Treat it as increasing the paper purchase price of your investment. When you eventually sell, a higher basis means less taxable gain.

Only assessments for capital improvements qualify for basis adjustment. An assessment to cover an operating shortfall, such as the building running over budget on heating costs, does not increase your basis. The board resolution usually makes the purpose clear. Keep the resolution, your payment receipts, and any correspondence explaining the project. Canceled checks or bank statements showing the payment amount and payee satisfy the IRS’s recordkeeping standards.¹¹

The Building Itself Has to Qualify

None of these deductions are available unless the corporation meets the IRS definition of a cooperative housing corporation. The building must satisfy at least one of three tests for the tax year in question:¹²

Gross income test: at least 80% of the corporation’s gross income comes from tenant-shareholders.
Square footage test: at least 80% of the building’s total square footage is used or available for residential purposes by tenant-shareholders.
Expenditure test: at least 90% of the corporation’s spending goes toward acquiring, building, managing, or maintaining the property for the benefit of tenant-shareholders.

Most residential co-ops pass at least one of these easily. The risk shows up in mixed-use buildings with significant commercial space. A ground-floor retail tenant generating substantial rent could push the building toward the boundary on the income test, and the square footage and expenditure tests exist as alternatives for exactly those situations. If your building has commercial tenants, confirm with the co-op’s accountant that the corporation still qualifies. You also have to be a tenant-stockholder in the statutory sense: your stock must be fully paid and correspond to your right to occupy a specific unit.¹
