Under IRC §163, mortgage interest on a primary or secondary home is deductible on Schedule A (itemized deductions) for loans up to $750,000 ($375,000 if married filing separately). For business or rental properties, 100% of mortgage interest is deductible on Schedule E or C.
Getting the deduction right is not just about whether it is allowed — it is about how you set it up.
For personal homes, you must itemize deductions. For rental/business properties, deduct on Schedule E or C.
Your lender sends Form 1098 showing annual mortgage interest paid.
Personal: Schedule A. Rental: Schedule E. Business: Schedule C or entity return.
Do not deduct mortgage interest above the $750,000 loan cap on personal residences.
If you have a home office, a portion of mortgage interest is deductible as a business expense under §280A.
When structured correctly, this deduction can significantly reduce your taxable income.
Here is how this deduction typically works in real situations:
A freelancer has a $500,000 mortgage at 7% = $35,000 interest/year and a 15% home office.
An LLC owns a rental property with $40,000 in annual mortgage interest.
Owner deducts mortgage interest above the $750,000 cap.
Key Takeaway: The difference between a valid deduction and a denied one usually comes down to documentation, usage percentage, and proper structuring. The same expense can be fully deductible, partially deductible, or not deductible at all — depending on how it is handled.
For a bona fide Airbnb or short-term rental property operated as a business, 100% of the mortgage interest is deductible, as it's considered a business expense. The $750,000 loan balance limit (or $1 million for loans before Dec 15, 2017) applies only to personal residences, not properties held for business purposes. This distinction is crucial for maximizing your deductions.
📞 Book a Free Call →IRS Publication 527, 'Residential Rental Property (Including Rental of Vacation Homes),' is the primary resource for understanding the deductibility of expenses related to short-term rentals. It details rules for distinguishing between rental property and personal use, and how to allocate expenses accordingly.
📞 Book a Free Call →No. If you rent out your home for fewer than 15 days during the tax year, the income is generally not taxable, and conversely, you cannot deduct any rental expenses, including mortgage interest, property taxes, or utilities, beyond what you'd typically deduct as a homeowner. This is often referred to as the 'de minimis' rule or the '14-day rule' under IRC Section 280A(g).
📞 Book a Free Call →The number of personal use days significantly impacts your expense deductions. If personal use exceeds the greater of 14 days or 10% of the total days rented at fair rental price, the property is considered a 'vacation home' (mixed-use). In this scenario, expenses must be allocated between rental and personal use, and rental deductions are limited to rental income. Consult IRS Pub 527 for detailed allocation rules.
📞 Book a Free Call →Deductible expenses are broad and include mortgage interest, property taxes, utilities, cleaning fees, repairs and maintenance, insurance premiums, advertising costs, professional fees (e.g., property management, accounting), supplies, and depreciation on the property and its furnishings. These must be 'ordinary and necessary' for the rental activity.
📞 Book a Free Call →Capital improvements, which add value, prolong useful life, or adapt the property to new uses (e.g., adding a deck, replacing a roof), are not immediately deductible. Instead, they must be capitalized and depreciated over their useful life, typically 27.5 years for residential rental property. Repairs, however, can be expensed in the year incurred.
📞 Book a Free Call →Uncle Kam advises meticulous record-keeping. You should retain all receipts, invoices, bank statements, credit card statements, booking confirmations, rental agreements, and calendars detailing rental and personal use days. Digital copies are acceptable, but ensure they are organized and easily retrievable, preferably for at least three years from the date you filed your original return.
📞 Book a Free Call →Yes, the cost of furniture, appliances, and other personal property used in your Airbnb unit is deductible through depreciation. These assets typically have a shorter depreciable life (e.g., 5 or 7 years) than the property itself. Bonus depreciation or Section 179 expensing might also apply, allowing for accelerated deductions in the year the items are placed in service.
📞 Book a Free Call →The building portion of your Airbnb property (excluding land value) is depreciated using the Modified Accelerated Cost Recovery System (MACRS) over 27.5 years for residential rental property. You'll need to determine the cost basis of the building and use IRS tables or a tax professional's guidance to calculate the annual depreciation deduction.
📞 Book a Free Call →The underlying expense deduction rules for the Airbnb activity itself (e.g., what constitutes an ordinary and necessary expense) generally remain the same whether you operate as a sole proprietorship, LLC (disregarded entity or partnership), or S-Corp. However, the reporting mechanism changes: Schedule C for sole props, Form 1065 for partnerships/multi-member LLCs, and Form 1120-S for S-Corps.
📞 Book a Free Call →No, you cannot deduct the value of your own labor or time spent cleaning, maintaining, or managing your Airbnb property. While these activities contribute to the business, the IRS only allows deductions for actual paid expenses. You can, however, deduct costs for supplies used during these activities or wages paid to others for performing these tasks.
📞 Book a Free Call →Yes, fees paid to a property manager for handling bookings, guest communication, and maintenance are fully deductible as ordinary and necessary business expenses. Similarly, fees paid to a tax professional for preparing your Schedule E (or other business tax forms) related to your rental activity are also deductible.
📞 Book a Free Call →Yes, you can still deduct expenses even if they result in a loss. However, these losses may be subject to passive activity loss (PAL) limitations under IRC Section 469. Generally, passive losses can only offset passive income. There's a special allowance for 'active participation' up to $25,000, and real estate professionals may be exempt from PAL rules, but this requires significant involvement.
📞 Book a Free Call →Yes, if the primary purpose of your travel is to manage, maintain, or improve your Airbnb property, the associated travel expenses (e.g., airfare, mileage, lodging, meals at 50%) are deductible. This applies to properties located away from your primary residence. Ensure you keep detailed logs and receipts to substantiate these expenses.
📞 Book a Free Call →While specific, detailed tax law updates for 2026 regarding Airbnb expense deductions are not yet codified, the Tax Cuts and Jobs Act of 2017 (TCJA) provisions, including the 20% Qualified Business Income (QBI) deduction, are set to expire or change after 2025. This could significantly impact the overall profitability of your Airbnb business. Uncle Kam recommends staying informed on legislative changes.
📞 Book a Free Call →Yes, subscription fees for services that directly aid in the operation and management of your Airbnb business are deductible. This includes platforms for dynamic pricing, channel management, guest messaging, or accounting software specifically used for your rental property. They are considered ordinary and necessary business expenses.
📞 Book a Free Call →A 'repair' keeps the property in good operating condition (e.g., fixing a leaky faucet, painting a room) and is fully deductible in the year incurred. An 'improvement' adds value, prolongs the life, or adapts the property to a new use (e.g., replacing the entire roof, adding a new bathroom) and must be capitalized and depreciated. This distinction is critical for proper tax treatment.
📞 Book a Free Call →Utilities are fully deductible for the periods the property is rented or available for rent. If you also use the property personally, you must allocate these expenses based on the percentage of rental use versus personal use. Only the portion attributable to the rental activity is deductible. Keep meticulous records of rental and personal days to justify your allocation.
📞 Book a Free Call →Yes, if you qualify as a 'real estate professional' under IRC Section 469(c)(7), you are generally exempt from the passive activity loss (PAL) limitations for your rental real estate activities, including Airbnb. This means you can deduct losses from your Airbnb against non-passive income (like W-2 wages) if other conditions are met. Qualification requires substantial participation in real estate trades or businesses.
📞 Book a Free Call →Yes, initial costs incurred to prepare your property for rental, such as professional photography, staging services, or even the costs of creating your listing on platforms like Airbnb, are generally considered ordinary and necessary business expenses. These can be deducted in the year they are incurred as part of getting your rental business operational.
