STR Tax Deductions Checklist 2026: Every Schedule C Write-Off for Short-Term Rental Hosts
If you operate a short-term rental and file Schedule C, you have access to dozens of tax deductions that most hosts either miss entirely or track poorly. This is the complete checklist — every deduction category, mapped to the exact Schedule C line item, with real-dollar examples so you can see what systematic tracking is actually worth.
Who This Checklist Is For
This guide is specifically for STR hosts who file Schedule C (Profit or Loss From Business) — meaning you materially participate in managing your rental and the IRS treats it as an active business, not a passive investment. If you're filing Schedule E, many of the same deductions apply, but the form and rules differ.
Not sure which schedule you should be filing? The short version: if your average guest stay is 7 days or fewer and you provide substantial services (cleaning between guests, concierge, supplies), the IRS generally considers this a business. If you meet the material participation test (most commonly: 100+ hours of personal involvement per year, and more than anyone else), you file Schedule C. When in doubt, ask your CPA — getting this classification right matters.
The 2026 Mileage Rate Update
Before we get into the full checklist, one important change: the IRS standard mileage rate for 2026 is $0.725 per mile (72.5 cents), up from $0.70 in 2025. This is the highest rate in IRS history. If you're filing your 2025 return now, use $0.70/mile. For trips you take in 2026, you'll use the new $0.725 rate when you file next year.
Either way, every trip to your property for cleaning, maintenance, supply runs, or guest check-ins is deductible. At $0.725/mile, a 30-mile round trip is worth $21.75 in deductions. Do that twice a week and you're looking at over $2,200/year in mileage deductions alone.
The Complete Deduction Checklist
Here's every deduction category, organized by the Schedule C line where it gets reported. Bookmark this — you'll want it at tax time.
Advertising & Marketing
Schedule C, Line 8Anything you spend to attract guests and promote your listing falls here. This goes beyond platform fees — think about all the ways you market your property.
Car & Travel Expenses (Mileage)
Schedule C, Line 9Every business-related trip to your property is deductible. You can choose the standard mileage rate ($0.725/mi for 2025, $0.725/mi for 2026) or track actual vehicle expenses — but you must choose one method and stick with it for that vehicle.
The IRS requires you to log the date, destination, business purpose, and miles driven for every trip. "I drove to the property a lot" won't survive an audit. Log each trip when it happens — not at tax time from memory.
Track Every Mile Automatically
DeductFlow's mobile app logs the date, destination, purpose, and distance for every trip — exactly what the IRS requires. Stop losing mileage deductions to bad record-keeping.

Commissions & Platform Fees
Schedule C, Line 10Every fee that booking platforms charge you is a business expense. This is often one of the largest deduction categories for STR hosts, and platforms report it on your 1099-K.
Contract Labor
Schedule C, Line 11Any independent contractors you pay $600 or more in a year need a 1099-NEC, and every dollar is deductible. This is separate from W-2 wages (which go on Line 26).
Insurance
Schedule C, Line 15Your STR insurance policy is fully deductible as a business expense. Standard homeowners insurance typically doesn't cover rental activity, so most hosts carry a specialized policy.
Mortgage Interest
Schedule C, Line 16aIf you have a mortgage on your STR property and it's used exclusively for rental, 100% of the interest is deductible. If you also use the property personally, you'll need to prorate based on rental vs. personal days. Your lender sends Form 1098 with the annual interest amount.
Legal & Professional Services
Schedule C, Line 17Every professional you hire to support your STR business is deductible. This includes the software tools you use to run the business.
Your DeductFlow subscription — or any tax tracking software — is itself a deductible business expense. Your tax tracking tools are a write-off on Line 18.
Repairs & Maintenance
Schedule C, Line 21Repairs that restore your property to its original condition are immediately deductible. Improvements that add value or extend the property's life must be depreciated instead. The distinction matters — a broken dishwasher repair is an expense; a kitchen remodel is a capital improvement.
Supplies & Furnishings
Schedule C, Line 22Guest-facing supplies and furnishings under $2,500 per item can generally be expensed immediately under the IRS de minimis safe harbor election. Items over $2,500 must be depreciated.
Taxes & Licenses
Schedule C, Line 23Property taxes on your STR are deductible as a business expense (separate from the SALT deduction on your personal return). Business licenses and occupancy tax obligations go here too.
Utilities
Schedule C, Line 25All utility costs for your STR property are deductible. If you also use the property personally, prorate based on rental vs. personal use days.
Wages
Schedule C, Line 26W-2 employee wages — including family members you hire — are deductible. If you hire your children under 18 and you're a sole proprietor, their wages are exempt from FICA taxes, making this a powerful tax strategy.
Other Expenses
Schedule C, Line 27aThe catch-all for legitimate business expenses that don't fit neatly into other categories. You'll list these on a separate statement attached to your return.
Depreciation & Cost Segregation
Schedule C, Line 13Your building (not the land) depreciates over 27.5 years for residential rental property. But a cost segregation study can reclassify components of your property into shorter depreciation schedules (5, 7, or 15 years), dramatically accelerating your deductions in the early years.
Capital improvements over $2,500 — new appliances, renovations, roof, HVAC systems — get depreciated rather than expensed immediately. The MACRS (Modified Accelerated Cost Recovery System) determines the schedule.
Cost segregation is the single highest-value tax strategy for STR hosts with properties valued above $300K. The study typically costs $3,000–$8,000 but can generate $50,000–$200,000 in first-year accelerated depreciation. If you haven't done one, talk to your CPA about whether it makes sense for your property.
What This Adds Up To
Let's put real numbers on it. A typical Colorado mountain STR generating $40,000–$60,000 in gross rental income might have deductions that look like this:
| Category | Typical Range |
|---|---|
| Mortgage Interest | $8,000 – $25,000 |
| Property Taxes & HOA | $3,000 – $8,000 |
| Cleaning & Turnover | $4,000 – $10,000 |
| Utilities | $3,000 – $6,000 |
| Insurance | $1,500 – $3,500 |
| Platform Fees | $1,200 – $3,000 |
| Repairs & Maintenance | $1,000 – $5,000 |
| Supplies & Furnishings | $800 – $3,000 |
| Mileage | $1,000 – $3,000 |
| Professional Services | $500 – $2,000 |
| Marketing | $300 – $1,500 |
| Depreciation (standard) | $10,000 – $15,000 |
| Total Potential Deductions | $34,300 – $85,000 |
At a 24% tax bracket (plus 15.3% self-employment tax on Schedule C income), every $1,000 in captured deductions saves you $361–$393 in taxes. The difference between tracking systematically and tracking loosely? Hosts who use structured systems typically capture 20–30% more deductions than those working from memory and bank statements.
The 5 Deductions Most Hosts Miss
Based on what I've seen from my own taxes and conversations with CPAs who specialize in STR:
1. Mileage. This is the number-one missed deduction. Hosts drive to their property constantly but almost never log individual trips. At $0.725/mile in 2026, even moderate driving adds up fast. See our complete IRS mileage deduction guide for tracking requirements.
2. Supply runs and small purchases. The $15 pack of batteries, the $40 welcome basket restock, the $25 cleaning supplies at Target. Individually small, collectively they can total $1,000–$3,000/year.
3. Professional services and software. Many hosts don't realize their CPA fees, bookkeeping tools, pricing software, and tax tracking subscriptions are all deductible.
4. Home office deduction. If you manage your STR from a dedicated space in your home, the simplified home office deduction ($5/sq ft, up to 300 sq ft = $1,500 max) is available.
5. Material participation hours. Not a deduction per se, but if you don't track your active hours, you can't prove material participation — which means you might be filing Schedule E instead of C, losing the ability to offset W-2 income with rental losses.
Stop Tracking in Spreadsheets. Get in the Flow.

How to Use This Checklist
Right now (if you're filing your 2025 return): Walk through each category above and check whether you've captured those expenses. Pull bank and credit card statements from 2025. Check for mileage you forgot to log. Make sure your CPA has everything categorized correctly.
Going forward (for 2026): Set up a tracking system now — whether it's DeductFlow, a spreadsheet, or even a dedicated folder in your phone's notes app. The best system is the one you'll actually use. Log expenses when they happen, not at year-end. Take photos of receipts the day you get them. Log mileage after every trip to your property.
The hosts who pay the least tax aren't the ones with the most creative accountants. They're the ones with the best records. For an even deeper dive into every deduction category, see our complete Airbnb tax deductions guide.
