The Complete Guide to STR Bookkeeping

A complete guide to short-term rental bookkeeping: the business account, software, and chart of accounts to set up once; recording gross revenue not the net payout; splitting the mortgage between P&L and balance sheet; and the monthly close that keeps it all clean.

Booking Net Platform Payouts vs. Gross Revenue: The Airbnb Accounting Error Compounding Your Tax Bill

How to Configure Class Tracking in QuickBooks Online for a Multi-Property STR Portfolio

Without class tracking, a multi-property STR operator has no way to produce a property-level P&L — only a blended number that obscures which property is profitable and which is dragging the portfolio.

The STR Chart of Accounts: Categorizing Nightly Rates, Cleaning Fees, and Pet Fees Separately

The default QuickBooks chart of accounts is built for generic small businesses. For an STR, every revenue stream needs its own account and every expense maps to a specific Schedule E line. Here’s the complete structure.

Automating Stripe and Payment Processor Reconciliations for Direct Booking Websites

Direct bookings through Stripe create a three-way reconciliation problem: gross charge, merchant fee, and net bank deposit — across a 2–3 day settlement window. Recording only the deposit understates income and eliminates your fee deduction.

Tracking Capital Reserves and Replacement Draws on Your Balance Sheet

A capital reserve is money set aside from operating cash flow to fund future major expenditures. It is not an operating expense — it doesn’t appear on your P&L when funded, and the tax treatment depends entirely on what it’s spent on.

The Complete Guide to Airbnb Tax Deductions: What STR Operators Can Actually Write Off

A practical guide to what short-term rental operators can actually write off — platform fees, depreciation, mileage, the home-office rules, and how your tax classification determines what those deductions are worth.

Cost Segregation Look-Back Studies: Form 3115 Mechanics for Accelerated Depreciation

If you purchased your STR without doing a cost segregation study, a Form 3115 look-back lets you claim all missed depreciation in the current year as a single catch-up deduction — without filing amended returns.

The 14-Day Personal Use Boundary: Navigating IRC Section 280A for Vacation Rentals

Exceeding 14 days of personal use converts your STR to a personal residence for tax purposes — eliminating your ability to deduct rental losses against W-2 income. Here’s how the rule works and how to stay under the threshold.

The Material Participation Time Log Guide: Satisfying IRS Section 469 Tests 1 & 3

Material participation is the second gate in the STR loophole. A documented time log — maintained contemporaneously, not reconstructed at year-end — is what separates a defensible position from an audit loss.

How the One Big Beautiful Bill Act (OBBBA) Impacts First-Year STR Depreciation

The OBBBA permanently restored 100% bonus depreciation for qualified property acquired after January 19, 2025. Here’s what changed, what qualifies, and what the full math looks like for a $500,000 STR acquisition.

Is Short-Term Rental Income Subject to Self-Employment Tax? Section 1402 Explained

Most STR operators are filing Schedule C when they should be on Schedule E — and paying self-employment tax they don’t owe. The average rental period test and the SE tax question are governed by two completely different code sections.

The Average Rental Period Test: What It Is, Why It Matters, and How to Get It Right

The 7-day rule determines whether your STR income is passive or non-passive — and that single classification changes your entire tax picture. Here’s how to get it right.

Deal Analysis

The RevPAN Blueprint: Why Revenue Per Available Night Is the Single Most Important STR Metric

ADR tells you what you charged. Occupancy tells you how often. RevPAN tells you whether the combination is actually working. It’s the single metric that collapses both pricing dimensions into one number.

How to Calculate Your True Break-Even Occupancy Floor (Excluding Cleaning Pass-Throughs)

Break-even occupancy is the minimum number of booked nights per month required to cover all costs. The correct formula uses contribution margin — not raw ADR — and must exclude cleaning fees from the calculation.

Modeling the First-Year STR Ramp-Up: Applying a Conservatism Discount to Market Data

A new STR listing doesn’t perform at market-average occupancy in months 1–4. Airbnb eliminated its New Listing Boost in late 2025. The correct underwriting model uses a two-phase ramp-up structure with a 10–15% conservatism discount applied.

Calculating the Seasonal Cash Reserve Floor: Protecting Cash Flow During Off-Peak Months

The seasonal cash reserve is specifically sized to cover predictable monthly gaps between slow-season revenue and monthly PITIA. It’s funded during peak season and drawn during slow months — an annual cycle, not a one-time buffer.

Entity Structure

Piercing the Corporate Veil: How Commingled Accounts Destroy Single-Member LLC Protections

The S-Corp Management Entity Layout: Structuring Active Operations for Substantial Service STRs

The S-Corp management entity structure applies to a narrow situation: an STR operator providing substantial services to guests such that income is correctly on Schedule C and subject to SE tax. For most STR operators, the structure provides zero benefit.

The Series LLC Structure for Growing Portfolios: Isolating Multi-Property Liability Safely

A Series LLC isolates each STR property in a legally separate cell within a single parent entity. A lawsuit against one cell cannot reach the assets of another. But the protection is only as strong as the cell separation you actually maintain.

Navigating the Due-on-Sale Clause When Transferring Personally Titled STRs into an LLC

Transferring a personally titled STR into an LLC technically triggers the due-on-sale clause in your mortgage. The correct approach is transparent lender notification before the transfer — not transfer first and disclosure later.
