Condo special assessments are generally not tax deductible when the unit is your home, and they usually are deductible in some form when the unit is a rental. What the money actually paid for, a repair or a capital improvement, controls the rest of the analysis. The label your association put on the invoice does not.
If the Condo Is Your Primary Home
The IRS lists condominium association fees, including special assessments, as nondeductible personal expenses.1Internal Revenue Service. Publication 530 (2025), Tax Information for Homeowners That covers the ordinary case: your board levies an assessment for a new roof, a lobby renovation, or a boiler replacement, and none of it goes on your return this year. There are a few narrow situations where a homeowner still gets a tax benefit, and they are worth checking before you write the assessment off entirely.
The Property Tax Sliver
If part of an assessment is specifically levied to cover local property taxes, that portion can count toward your state and local tax (SALT) deduction. For 2025, the SALT cap is $40,000 per return, or $20,000 if married filing separately, with a phasedown for taxpayers whose modified adjusted gross income exceeds $500,000 ($250,000 married filing separately). The phasedown reduces the cap by 30 cents on every dollar of income above the threshold, bottoming out at $10,000 ($5,000 married filing separately). These figures are set to rise 1% annually.1Internal Revenue Service. Publication 530 (2025), Tax Information for Homeowners
Assessments for maintenance, repairs, or building projects are not property taxes, even when they appear on the same bill. Assessments for local improvements that raise property value, such as new sidewalks or sewer connections, are also not deductible as taxes and instead get added to your basis.2Internal Revenue Service. Real Estate (Taxes, Mortgage Interest, Points, Other Property Expenses)
Basis Adjustment at Sale
A capital improvement assessment on your home does produce a tax benefit, just not this year. The amount you paid increases your adjusted basis in the unit, which reduces your taxable gain whenever you sell.3Office of the Law Revision Counsel. 26 USC 1016 – Adjustments to Basis A $15,000 assessment for a full roof replacement adds $15,000 to your basis; when you sell years later, your gain is $15,000 lower than it otherwise would be. A repair assessment does not increase basis because it did not add lasting value. This is the single strongest reason to keep every assessment record for as long as you own the unit.
Energy Credits for Association Upgrades
Most owners miss this one. When a condo association uses assessment money to install qualifying energy-efficient equipment, the IRS treats each owner as having paid their proportionate share for purposes of the Energy Efficient Home Improvement Credit.4Internal Revenue Service. Energy Efficient Home Improvement Credit – Qualifying Residence If the association spends $100,000 on qualifying high-efficiency heat pumps and you own a 5% interest in the common elements, you are treated as spending $5,000.
The credit runs up to $2,000 per year for heat pumps and biomass stoves and up to $1,200 per year for other qualifying items like insulation, exterior windows, and exterior doors.5Internal Revenue Service. Energy Efficient Home Improvement Credit A credit reduces your tax bill dollar for dollar, which is worth more than a deduction of the same size. The association’s governing body chooses a reasonable method for allocating each owner’s share and must keep consistent records.
Accessibility Improvements as Medical Expenses
An assessment funding accessibility modifications can count as a medical expense if the primary purpose is medical care for you, your spouse, or a dependent. The IRS presumes certain modifications do not increase a home’s value, which means the full cost qualifies: entrance ramps, widened doorways, bathroom grab bars and support rails, modified kitchen cabinets, and modified fire alarms or warning systems.6Internal Revenue Service. Publication 502 (2025), Medical and Dental Expenses
For improvements that do raise property value, the medical expense equals the cost minus the increase in value. Either way, only the total medical expenses above 7.5% of your adjusted gross income are deductible, and you have to itemize. Uncommon, but real, and worth flagging to your accountant if it fits your situation.
Interest If You Borrow to Pay
Some owners take out a home equity loan or line of credit to cover a big assessment. Interest on that loan is deductible only if the borrowed money was used to buy, build, or substantially improve the home securing the loan.1Internal Revenue Service. Publication 530 (2025), Tax Information for Homeowners An assessment funding a capital improvement to the building may qualify. A repair assessment will not.
If the Condo Is a Rental
The picture changes when you rent the unit out. Both repair and improvement assessments produce a tax benefit; the timing is what differs.
Repair Assessments Deduct Now
Assessments funding repairs are deductible in full as ordinary and necessary rental expenses in the year you pay them.7Internal Revenue Service. Tips on Rental Real Estate Income, Deductions and Recordkeeping Patching stucco, fixing a leaking common-area pipe, or replacing a handful of broken windows all fall here. You report the deduction on Schedule E and it offsets rental income immediately.8Internal Revenue Service. Publication 527 (2025), Residential Rental Property
Improvement Assessments Get Capitalized
Assessments for capital improvements cannot be written off in one year. You add the cost to your property’s adjusted basis and recover it through depreciation.8Internal Revenue Service. Publication 527 (2025), Residential Rental Property The default recovery period for residential rental property is 27.5 years, straight-line, with a mid-month convention. A $55,000 capitalized assessment yields roughly $2,000 a year in depreciation. Depreciation starts when the improvement is placed in service, and only the portion allocable to the building structure is depreciable.
A single assessment often funds both categories. If $20,000 pays to repaint hallways (repair) and $80,000 goes to replacing the electrical system (improvement), those portions receive different treatment. Without a written allocation from the board, the IRS may deny the immediate deduction on the repair share.
Bonus Depreciation Can Accelerate the Improvement Piece
The One Big Beautiful Bill Act permanently restored 100% bonus depreciation for qualifying property acquired after January 19, 2025.9Internal Revenue Service. Treasury, IRS Issue Guidance on the Additional First Year Depreciation Deduction Amended as Part of the One Big Beautiful Bill For special assessments, this matters because a cost segregation study can reclassify components of a capital improvement into shorter-lived categories. Landscaping, parking lot resurfacing, decorative lighting, and certain use-specific plumbing or electrical work may fall into 5-, 7-, or 15-year recovery periods rather than 27.5. Under current bonus depreciation rules those reclassified components can be deducted entirely in year one.
Cost segregation studies require an engineering analysis and are not cheap, so they make sense mainly on large assessments. On a building-wide assessment where your unit’s share runs into five figures, accelerating even a fraction of the cost can produce real savings up front.
If You Use Part of the Condo for Business
A qualified home office lets you deduct a proportionate share of housing expenses, including a special assessment. You calculate the business percentage two ways: office square footage divided by total unit square footage, or, if the rooms are roughly equal in size, number of business-use rooms divided by total rooms.10Internal Revenue Service. Publication 587, Business Use of Your Home
Apply that percentage to the assessment. If the office occupies 15% of your unit, 15% of a repair assessment is deductible as a business expense, and 15% of a capital improvement assessment gets capitalized and depreciated. The remaining 85% follows the primary-residence rules above, meaning no current deduction but a basis increase for the improvement portion.
Repair Versus Improvement: The Distinction That Decides Everything
Under the tangible property regulations, an expense counts as an improvement if it fixes a pre-existing defect or material condition, makes a material addition (bigger, stronger, or more capacity), or adapts the property to a different use.11eCFR. 26 CFR 1.263(a)-3 – Amounts Paid to Improve Tangible Property Everything else is a repair.
In plain terms: patching a roof leak, fixing a broken boiler, and repainting hallways are repairs. Replacing an entire roof, installing a new elevator, adding a swimming pool, and upgrading a building’s HVAC to a higher-efficiency system are improvements. The IRS looks at whether the work materially increased the property’s productivity, efficiency, strength, or output. Cost alone does not decide it.12Internal Revenue Service. Tangible Property Final Regulations
What to Keep on File
The IRS will not accept your characterization of an assessment without support. Get the association’s resolution authorizing the assessment, a written scope of work, contractor invoices or bids, and a clear allocation between repair and improvement portions when both apply. For capital improvements that increase your basis, keep the records at least three years past the due date of the return for the year you sell the property.13Internal Revenue Service. Publication 523, Selling Your Home
Practically, that means holding the records for as long as you own the unit plus three years. Buy in 2026, pay an assessment in 2028, sell in 2045, and you need the 2028 paperwork until at least 2049. A dedicated digital folder per property, updated every time you pay, is the simplest way to keep a deduction or basis adjustment from evaporating during an audit.
