Short-Term Rental Tax Basics for San Diego Owners

## TAX DISCLAIMER **IMPORTANT:** This article is for informational purposes only and does not constitute tax, legal, or financial advice. Tax laws are complex and change frequently. Every property owner's situation is unique. Always consult with a qualified CPA or tax professional before making tax-related decisions for your short-term rental property. The information provided here reflects general guidelines as of the publication date and may not apply to your specific circumstances. --- ## Understanding Short-Term Rental Taxes Operating a short-term rental in San Diego means navigating multiple layers of taxation. As an STR owner, you are responsible for collecting and remitting local transient occupancy taxes, reporting rental income on your federal and state tax returns, and tracking expenses that qualify as deductions. The good news? Many expenses you already incur are tax-deductible, which can significantly reduce your tax burden. Understanding these obligations—and opportunities—is essential for running a profitable STR business. Before diving into specifics, make sure you are operating legally. Review our complete guide to [San Diego short-term rental regulations](/blog/san-diego-short-term-rental-regulations) to ensure your property is properly licensed and compliant with local laws. --- ## San Diego Transient Occupancy Tax (TOT) Requirements ### What Is TOT? The Transient Occupancy Tax, commonly called the "hotel tax" or "bed tax," is a local tax that San Diego requires all short-term rental operators to collect from guests and remit to the city. This tax applies to any rental of 30 consecutive days or fewer. ### Current TOT Rates (Effective May 1, 2025) San Diego voters approved Measure C, which created a tiered TOT system based on proximity to the San Diego Convention Center: | Tax Zone | TOT Rate | Location | |----------|----------|----------| | Zone 1 | 11.75% | Farthest from Convention Center | | Zone 2 | 12.75% | Mid-distance from Convention Center | | Zone 3 | 13.75% | Closest to Convention Center | Prior to May 1, 2025, all properties paid a uniform 10.5% rate. You can determine your property's tax zone using the City of San Diego's interactive tax zone lookup map. ### Tourism Marketing District (TMD) Assessment In addition to TOT, San Diego imposes a Tourism Marketing District Assessment of 0.55% on short-term rentals with fewer than 70 rooms. This fee funds tourism promotion activities. ### How to Collect and Remit TOT **Platform Collection:** Both Airbnb and Vrbo automatically collect TOT for San Diego listings, simplifying compliance for most hosts. **Direct Bookings:** If you accept bookings directly (through your own website or other channels), you must: 1. Register with the San Diego City Treasurer 2. Collect TOT from guests at checkout 3. File monthly or quarterly returns 4. Remit collected taxes by the due date Failure to collect or remit TOT can result in penalties, interest, and potential loss of your STR license. --- ## Common Tax Deductions for STR Owners One of the biggest advantages of owning a short-term rental is the ability to deduct legitimate business expenses. Here are the most common deductions available to San Diego STR owners: ### 1. Platform and Booking Fees Fees charged by Airbnb, Vrbo, Booking.com, and other platforms are 100% deductible. These typically range from 3-15% of each booking. ### 2. Cleaning and Turnover Costs The frequent guest turnover in STRs makes cleaning a significant—and fully deductible—expense. This includes: - Professional cleaning services - Cleaning supplies and products - Laundry services for linens - Restocking consumables (toiletries, coffee, etc.) ### 3. Maintenance and Repairs Routine maintenance keeps your property guest-ready and is fully deductible. Examples include: - HVAC servicing and filter replacements - Plumbing repairs - Appliance repairs - Pest control - Pool and spa maintenance For guidance on maintaining your property efficiently, see our [comprehensive STR maintenance guide](/blog/str-maintenance-checklist-san-diego). ### 4. Insurance STR-specific insurance premiums are deductible, including: - Short-term rental insurance policies - Umbrella liability coverage - Host protection insurance ### 5. Utilities If your property is exclusively used for rentals, utilities are 100% deductible: - Electricity - Gas - Water and sewer - Trash collection - Internet and cable - Security monitoring ### 6. Property Management Fees If you use a professional property manager like [Ooda Airbnb Management](https://www.oodahost.com), management fees are fully deductible business expenses. ### 7. Mortgage Interest The portion of mortgage interest attributable to rental use is deductible. If you use the property personally, you must prorate this deduction based on rental vs. personal use days. ### 8. Property Taxes Real estate taxes are deductible, prorated for rental use if applicable. ### 9. Supplies and Furnishings Items that enhance the guest experience are deductible: - Furniture and decor - Kitchen equipment and utensils - Bedding and towels - Welcome gifts and amenities - Smart home devices (locks, thermostats) Items under $2,500 can typically be expensed immediately. Larger purchases may need to be depreciated. ### 10. Professional Services Fees paid to professionals who help run your STR business: - Accountant/CPA fees - Legal fees - Photography for listings - Marketing and advertising costs ### 11. Travel Expenses If you travel to your rental property for business purposes (inspections, maintenance oversight, guest issues), you can deduct: - Mileage (67 cents per mile for 2024) - Airfare and lodging (if property is distant) - Meals (50% deductible) ### 12. Home Office Deduction If you manage your STR from a dedicated home office space, you may qualify for the home office deduction. The simplified method allows $5 per square foot, up to 300 square feet ($1,500 maximum). --- ## The 14-Day Rule Explained ### What Is the 14-Day Rule? The IRS 14-day rule—sometimes called the "Augusta Rule" or "Masters Exception"—provides a powerful tax benefit for property owners who rent their homes occasionally. **The rule states:** If you rent your property for 14 days or fewer per year AND use it personally for more than 14 days (or 10% of rental days, whichever is greater), you do not need to report any rental income on your tax return. ### How It Works **Example:** You rent your San Diego beach house for two weeks during Comic-Con, earning $8,000. You use the property yourself for summer vacations totaling 30 days. Under the 14-day rule, that $8,000 is completely tax-free—you do not report it as income. ### Important Caveats 1. **No expense deductions:** While you do not pay tax on the rental income, you also cannot deduct rental expenses. You can still claim standard homeowner deductions (mortgage interest, property taxes) on Schedule A. 2. **Strict day counting:** The IRS counts partial days. If guests check out at 11 AM and you arrive at 6 PM, that is both a rental day and a personal use day. 3. **Personal use definition:** Days used by family members (siblings, parents, children, grandchildren) count as personal use, even if they pay fair market rent. Renting to non-family at fair market value does not count as personal use. ### When the 14-Day Rule Does NOT Apply If you rent for more than 14 days annually, all rental income becomes taxable. However, you can then deduct rental expenses proportionally based on rental vs. personal use days. --- ## Understanding Depreciation ### What Is Depreciation? Depreciation allows you to deduct the cost of your rental property (excluding land) over its useful life. For residential rental properties, the IRS requires a 27.5-year recovery period using the straight-line method. ### How to Calculate Depreciation 1. **Determine your property's basis:** Purchase price + closing costs + improvements - land value 2. **Divide by 27.5:** This gives your annual depreciation deduction **Example:** You purchased a condo for $500,000. The land is valued at $100,000. Your depreciable basis is $400,000. Annual depreciation: $400,000 / 27.5 = $14,545. ### Short-Term Rentals and Depreciation Here is where STRs get interesting. Because short-term rentals with average stays of 7 days or fewer are treated more like hotel businesses than passive rentals, they may qualify for accelerated depreciation strategies. **Cost Segregation:** A cost segregation study can identify property components (appliances, flooring, fixtures) that can be depreciated over 5, 7, or 15 years instead of 27.5 years. This front-loads deductions, reducing taxes in early years. **Bonus Depreciation:** Following recent tax law changes, qualified property placed in service after January 19, 2025 may again be eligible for 100% bonus depreciation on certain components. ### Depreciation Recapture Warning When you sell your property, the IRS "recaptures" depreciation you have claimed by taxing it at up to 25%. This does not mean depreciation is bad—the time value of money usually makes taking depreciation beneficial—but you should plan for this eventual tax liability. --- ## Record-Keeping Best Practices Thorough documentation protects you in an audit and ensures you capture every legitimate deduction. ### What to Keep **Income Records:** - Platform payout statements (Airbnb, Vrbo) - Direct booking receipts - Security deposit records - Calendar of rental dates and rates **Expense Records:** - Receipts for all purchases - Invoices from service providers - Bank and credit card statements - Mileage logs for property-related travel **Property Records:** - Purchase documents and closing statements - Improvement receipts (for basis calculations) - Depreciation schedules - Insurance policies **Usage Logs:** - Calendar tracking rental days vs. personal use days - Maintenance and repair visit documentation ### How Long to Keep Records | Record Type | Retention Period | |-------------|------------------| | Tax returns and supporting documents | 7 years | | Property purchase/improvement records | Duration of ownership + 6 years | | Depreciation schedules | Duration of ownership + 6 years | | Expense receipts | 7 years | ### Tools for Organization - **Dedicated bank account:** Separate STR income and expenses from personal finances - **Accounting software:** QuickBooks, Stessa, or similar tools designed for rental properties - **Cloud storage:** Digital copies of all receipts and documents - **Property management software:** Platforms like Guesty or Hostaway can generate financial reports --- ## When to Hire a CPA While basic STR tax situations can be handled with tax software, consider hiring a CPA specializing in real estate or short-term rentals if: - You own multiple properties - You are considering cost segregation or accelerated depreciation strategies - You want to use the STR loophole to offset W-2 income - Your rental income exceeds $25,000 annually - You have complex personal use situations - You are being audited A good CPA can often save you more in taxes than their fee costs. Look for someone familiar with: - IRS Publication 527 (Residential Rental Property) - Short-term rental classification rules - California state tax requirements - Local San Diego tax obligations --- ## Let Ooda Handle the Complexity Managing short-term rental taxes alongside daily operations, guest communications, and property maintenance is a lot to handle on your own.
