Do I need an EIN for my Airbnb rental?

You don't strictly need an EIN if you're a sole proprietor with no employees — you can use your Social Security Number. However, getting an EIN is recommended: it lets you open a business bank account, avoid giving your SSN to contractors, and prepares you for potential future LLC formation. EINs are free from the IRS at irs.gov.

When do I need to pay quarterly estimated taxes for my Airbnb income?

If you expect to owe $1,000 or more in federal taxes for the year from your STR income, you're required to make quarterly estimated payments. The 2026 due dates are April 15, June 15, September 15, and January 15 (for the Q4 payment). Underpaying estimated taxes results in an underpayment penalty.

How do I find my property's depreciation basis?

Your depreciation basis is the cost of the property (or fair market value at the time you converted it to rental use) minus the land value. Land is not depreciable. Use your property tax assessment to estimate the land-to-building split, or get a separate land appraisal. Your closing statement shows the purchase price, which is your starting point.

New STR Host Tax Setup Guide: Do These 5 Things in Year One

Start Your 7-Day Free Trial

No credit card required

Most new STR hosts think about taxes for the first time in January when they get their Airbnb 1099-K. By then, it's too late to fix many first-year mistakes. The five steps in this guide take less than a day to complete and set you up to capture every deduction, avoid common penalties, and hand your CPA organized records — not a shoebox — at the end of the year.

Step 1: Get an EIN and Open a Business Bank Account

Step 1

EIN + Dedicated Business Banking

The single most important structural step for any new STR host is separating your STR finances from your personal finances. This means a dedicated bank account and credit card used only for STR income and expenses.

Get an EIN: An Employer Identification Number is free from the IRS at irs.gov/ein (takes 5 minutes online). You don't need employees to have an EIN. Benefits: you can open a business bank account without your SSN, give your EIN to contractors instead of your SSN, and have a cleaner audit trail.

Open a business checking account: Use any bank or credit union — many offer free business checking. Deposit all Airbnb/VRBO payouts into this account. Pay all STR-related expenses from this account or a dedicated business credit card. The clean separation makes expense tracking infinitely easier and creates a defensible record for the IRS.

Why this matters: Mixed personal and business finances require transaction-by-transaction review at tax time, create confusion about what qualifies as a business expense, and make the "separate your STR business" argument harder to make to an auditor.

Step 2: Set Up Expense Tracking From Day One

Step 2

Real-Time Expense and Mileage Tracking

Set up DeductFlow (or at minimum a spreadsheet) before your first booking. Log every expense as you incur it — don't wait until year-end. Log every STR-related drive in real time.

What to track:

Every expense paid from your STR bank account or credit card
Every drive to and from the property, to hardware stores, supply runs, and contractor meetings
Every hour you spend on STR activities (critical if you plan to claim material participation)

Expense categories to use: Match to Schedule C lines from the start. Cleaning contractors → Line 11. Supplies → Line 22. Insurance → Line 15. Mortgage interest → Line 16. Platform fees → Line 27a. Using the right categories from day one means your records are already organized when you hand them to your CPA.

Step 3: Establish Your Depreciation Basis

Step 3

Document Your Property's Depreciation Basis

Depreciation is your largest deduction — and the one most often set up incorrectly in year one. Getting the basis right matters because it affects every future year's deduction and the gain calculation when you eventually sell.

Find your building value (not land): Land is not depreciable. Your depreciable basis is the purchase price (or fair market value at conversion to rental use) minus the land value. Two ways to estimate the land split:

Property tax assessment: Your county assessment separates land and improvement value. Use the percentage split to allocate your purchase price. If the assessment shows 20% land / 80% improvement, apply that to your purchase price.
Appraisal: A formal appraisal provides the most defensible land valuation. For high-value properties, consider getting an appraisal at the time of acquisition or rental conversion.

Document new assets: Every piece of furniture, appliance, or equipment purchased for the rental is a separately depreciable asset. Keep purchase invoices, note the purchase date, and categorize: furniture (5-year), appliances (7-year). These assets may qualify for bonus depreciation in the year purchased.

Enter your property and assets in DeductFlow's depreciation tracker immediately. See our guide to tracking depreciation in DeductFlow.

Step 4: Collect W-9s from Cleaners Before First Payment

Step 4

W-9 From Every Contractor, Before First Payment

If you pay any individual contractor $600 or more in a calendar year, you must issue a 1099-NEC. Collecting the W-9 after year-end is difficult and sometimes impossible — people move, become unresponsive, or refuse. The rule: W-9 before first payment, every time.

Who needs a W-9: Your cleaning contractor, handyperson, landscaper, photographer — any individual (not a corporation) you pay for services related to your STR. Download the W-9 form free at irs.gov, email it to the contractor, and keep the signed copy in your records.

Track payments by person: Maintain a running total for each contractor throughout the year. When any individual crosses $600 in total payments, you'll need to file a 1099-NEC by January 31 of the following year.

DeductFlow's contractor tracking flags when any individual approaches the $600 threshold so you're not surprised in January. See our guide to tracking contractor payments.

Step 5: Set Up Quarterly Estimated Tax Payments

Step 5

Quarterly Estimated Taxes

As an STR host, you're running a self-employment business. Unlike W-2 employees, no one withholds taxes from your payouts. If you expect to owe $1,000 or more in federal taxes for the year, you're required to make quarterly estimated payments — or face an underpayment penalty.

2026 due dates:

April 15, 2026 (for Jan 1 – Mar 31 income)
June 16, 2026 (for Apr 1 – May 31 income)
September 15, 2026 (for Jun 1 – Aug 31 income)
January 15, 2027 (for Sep 1 – Dec 31 income)

How to calculate: Your quarterly estimated tax should cover both income tax (your effective rate on STR income) and self-employment tax (15.3% on net self-employment income). A simple approach: set aside 25–30% of each Airbnb payout in a savings account, then verify with your CPA each quarter whether that's on track.

How to pay: The easiest method is IRS Direct Pay at irs.gov or through the IRS2Go app. For larger amounts, EFTPS (Electronic Federal Tax Payment System) is preferred.

Common First-Year Mistakes to Avoid

Missing startup expenses: Costs incurred before your first booking — furniture, supplies, photography, registration fees — are often deductible as startup costs or immediate business expenses. Don't start your tracking after the first guest; start it when you start spending.
Ignoring the depreciation basis: You can only deduct what you can document. If you don't establish your depreciation basis properly in year one, it's harder (and sometimes impossible) to correct later.
Skipping the W-9 conversation: Asking for a W-9 after you've already paid someone for a year is awkward and often unsuccessful. Build it into your contractor onboarding from day one.
Using personal funds for STR expenses: Mixing personal and business finances creates work, creates confusion, and creates audit risk. Separate banking pays dividends for years.
Not logging material participation hours: If you ever want to use the STR loophole, you need a contemporaneous time log from the day you start. You cannot reconstruct a year's worth of hours in January.
