Every deduction, depreciation math, the $25K passive loss exception, Airbnb tax rules, and the depreciation recapture trap when you sell — with real numbers.
Rental income is taxable as ordinary income — taxed at your marginal tax rate, just like wages. However, rental real estate comes with a unique set of deductions that can significantly reduce or even eliminate the taxable income from your rental property. The effective tax rate on rental income for most investors is far lower than the headline rate suggests, because expenses and depreciation reduce taxable income substantially.
Rental income includes: rent payments, advance rent, security deposits applied to rent, lease cancellation fees, and any services provided by tenants in lieu of rent. Security deposits you intend to return are NOT income when received — they only become income if you keep them.

A repair maintains your property's current condition (deductible immediately): fixing a broken window, patching a roof leak, repainting. An improvement adds value or extends useful life (capitalized and depreciated): new roof, new HVAC, kitchen renovation. The distinction matters significantly for tax timing.
Depreciation is the IRS's acknowledgment that buildings wear out over time. You can deduct the cost of the building (not land) over 27.5 years for residential rental property. This is a non-cash deduction — you don't actually spend money, but you get a tax deduction anyway.
The calculation: Purchase price minus land value = depreciable basis. Divide by 27.5 = annual depreciation deduction. On a $300,000 property where land is valued at $60,000: ($300,000 - $60,000) / 27.5 = $8,727/year in depreciation deductions — regardless of whether you profit or not.
Cost segregation: A cost segregation study accelerates depreciation by identifying components (appliances, carpeting, fixtures) that depreciate faster than 27.5 years. On larger properties, this can front-load hundreds of thousands in deductions. Generally worth the cost ($3,000–$15,000) for properties over $1M.
Rental income is classified as 'passive activity income.' This matters because passive losses can only offset passive income — generally, you can't use rental losses to reduce your W-2 wages. However, there's an important exception:
The $25,000 allowance: If you 'actively participate' in managing your rental (make management decisions, approve tenants, approve repairs) AND your modified adjusted gross income (MAGI) is under $100,000, you can deduct up to $25,000 in rental losses against ordinary income. This allowance phases out between $100,000–$150,000 MAGI.
Real Estate Professional status: If you spend more than 750 hours per year in real estate activities AND more than 50% of your working hours are in real estate, rental losses are not limited by passive activity rules. This is a high bar but provides enormous tax flexibility for active real estate investors.
Short-term rentals — defined as average guest stay of 7 days or fewer — have different tax treatment than long-term rentals. If you also provide substantial services (meals, daily cleaning, concierge), the rental income may be treated as active business income rather than passive rental income.
When you sell a rental property, two tax events occur:
Capital gains tax: Profit above your adjusted basis (purchase price + improvements - depreciation taken) is taxed at long-term capital gains rates (0%, 15%, or 20%) if held over one year, plus the 3.8% Net Investment Income Tax if income exceeds thresholds.
Depreciation recapture: All depreciation you've taken over the years is 'recaptured' and taxed at up to 25% when you sell. On a property held 10 years with $8,727/year depreciation, that's $87,270 in recaptured depreciation taxed at 25% = $21,818 in additional taxes at sale.
1031 exchange: You can defer all capital gains and depreciation recapture taxes by exchanging into a 'like-kind' property within specific timelines (45 days to identify, 180 days to close). This is the most powerful tax deferral tool available to real estate investors.
