Renting your home or a spare room on Airbnb looks simple until tax season hits. Then you're faced with questions about Schedule E, Schedule C, depreciation, and the infamous 14-day rule. This guide walks through all of it so you can file correctly and keep more of what you earn.
The 14-Day Rule: The Rule That Determines Everything
The IRS uses a simple threshold to classify your rental activity: the 14-day rule (IRC §280A).
Here is how it works:
- If you rent your home for 14 days or fewer per year, the rental income is completely tax-free. You report nothing and deduct nothing. This is sometimes called the "Augusta Rule" (more on that below).
- If you rent for more than 14 days, the IRS considers it a rental property and you must report all rental income.
There is a secondary test: if your personal use exceeds the greater of 14 days or 10% of the days you rented the property, the IRS treats it as a personal residence with rental activity — not a full rental property. This distinction matters because it limits which expenses you can deduct.
Example: You rent your home 120 days and personally use it 25 days. The 10% threshold is 12 days (10% of 120). Your personal use of 25 days exceeds both 14 days and 12 days, so the IRS treats this as a mixed-use personal residence.
Example 2: You rent a separate guest house 200 days and never personally use it. This is a pure rental property with no mixed-use complications.
Schedule E vs Schedule C: Which One Do You File?
This is the most common point of confusion for Airbnb hosts. The answer depends on the services you provide.
Schedule E — Rental Income (Most Hosts)
Most Airbnb hosts file Schedule E. This is the correct form when you are renting property and providing only basic services that come standard with real estate rentals — things like cleaning between guests, furnishings, and utilities.
Schedule E income is not subject to self-employment (SE) tax, which is a significant advantage. Your net rental income is taxed at your ordinary income rate, but you avoid the 15.3% SE tax hit.
Schedule C — Business Income (Some Hosts)
If you provide substantial services beyond standard rental accommodations, the IRS may treat your activity as a business on Schedule C. "Substantial services" means things like daily maid service, meals, concierge-style experiences, or hotel-like amenities.
The distinction is similar to the difference between renting an apartment and running a bed-and-breakfast. Most short-term rental hosts do not cross this line, but if you are offering curated experiences with personal attention and ongoing services, talk to a tax professional about your classification.
The downside of Schedule C: all net profit is subject to SE tax (15.3% on the first $168,600 of net income in 2024). The upside: it may open up additional deductions like the home office deduction.
Deductible Expenses for Airbnb Hosts
Whether you file Schedule E or Schedule C, you can deduct the ordinary and necessary expenses of your rental activity. Here is what qualifies:
Direct Rental Expenses (100% Deductible)
- Cleaning fees you pay between guests
- Supplies: toiletries, coffee, paper towels, linens, kitchen supplies left for guests
- Platform fees: Airbnb charges hosts roughly 3% of each booking as a service fee — fully deductible
- Repairs made specifically for the rental
- Listing photography and marketing costs
Prorated Expenses (Mixed-Use Properties)
If you use the property personally and rent it out, you must prorate shared expenses. The standard formula is:
Rental days / (Rental days + Personal use days) = Rental percentage
Apply that percentage to:
- Mortgage interest (the rental portion goes on Schedule E; the personal portion goes on Schedule A if you itemize)
- Property insurance
- Utilities: electricity, gas, water, internet
- HOA fees
Depreciation
Depreciation is one of the most powerful deductions available to rental property owners and one of the most overlooked.
Residential rental property is depreciated over 27.5 years using the straight-line method. Your depreciable basis is the purchase price plus closing costs, minus the value of the land (land is not depreciable).
Example: You paid $300,000 for a property. The assessor values the land at $60,000. Your depreciable basis is $240,000. Annual depreciation = $240,000 / 27.5 = $8,727 per year.
For a mixed-use property, depreciate only the rental-use percentage of the basis.
One important note: when you sell the property, the IRS "recaptures" depreciation at a 25% rate. This is called depreciation recapture. It is still usually worth taking the deduction now, but be aware of the future tax cost.
The Augusta Rule: Tax-Free Income Up to 14 Days
IRC §280A(g) is one of the most favorable provisions in the tax code for homeowners. If you rent your primary residence for 14 days or fewer in a calendar year, the income is completely excluded from your gross income. You do not even need to report it on your return.
This applies even if you charge market rates for a major event — like a Super Bowl, Masters Tournament, or a corporate conference in your city. Fourteen days of rental income, completely tax-free.
The trade-off: you also cannot deduct any rental expenses for those days. But given that the income is tax-free, this is almost always a favorable outcome.
The 1099-K: What Airbnb Reports to the IRS
Airbnb is required to issue a 1099-K to hosts who meet the reporting threshold:
- 2024: $5,000 or more in gross payments
- 2025 and beyond: $600 or more (when the IRS's long-delayed lower threshold takes full effect)
The 1099-K reports your gross rental receipts — meaning the total paid by guests before Airbnb takes its platform fee. This means if guests paid $10,000 total and Airbnb kept $300 in host fees, your 1099-K will show $10,000. You then deduct the $300 in fees as an expense.
Even if you do not receive a 1099-K (because you fall below the threshold), you are still legally required to report all rental income.
Prorating Mixed-Use Property: A Practical Walkthrough
Here is a simplified example of how to prorate for a mixed-use property:
- Total days in year: 365
- Days rented: 120
- Days of personal use: 30
- Days vacant (no use): 215
Rental percentage = 120 / (120 + 30) = 80%
Apply 80% to mortgage interest, insurance, utilities, and depreciation to get the deductible rental portion.
Key Takeaways
- The 14-day rule determines whether your rental income is taxable at all
- Most Airbnb hosts file Schedule E, not Schedule C, and avoid SE tax
- Depreciation is worth calculating even if it seems complex — it reduces your taxable income significantly
- The Augusta Rule lets you earn tax-free rental income for up to 14 days per year
- Your 1099-K shows gross receipts; deduct platform fees separately
