Vacation rental owners face bookkeeping challenges that traditional landlords don’t deal with. The combination of platform payouts, frequent turnovers, and mixed personal use creates plenty of opportunities to get things wrong.

The most common mistake is treating platform deposits as gross revenue. When Airbnb sends you $1,847, that’s not what the guest paid. The guest might have paid $2,100 with Airbnb taking their service fee, plus there’s a cleaning fee that should pass through to your cleaner, plus occupancy taxes that Airbnb may or may not have collected depending on your location. Recording $1,847 as income without breaking out the components means your revenue is understated and your expenses are wrong.

Not reconciling platform reports with bank deposits compounds this problem. Airbnb and VRBO provide detailed transaction reports, but many owners never download them. They just look at bank deposits and guess at categorization. A vacation rental with 40 bookings per year needs proper reconciliation or the numbers will be off by thousands.

Personal use tracking trips up owners who also use their property. The IRS requires you to track personal use days versus rental days. Your deductible expenses depend on this ratio. Owners who don’t track this accurately either overclaim deductions and risk audit problems, or underclaim and pay more tax than necessary. Keep a simple log of every night the property is used and by whom.

Misclassifying repairs versus improvements costs money in both directions. Replacing a broken faucet is a repair you deduct this year. Renovating the bathroom is an improvement you depreciate over time. Owners tend to either expense everything, missing the depreciation benefits on larger projects, or capitalize small repairs that should reduce this year’s taxes. The distinction matters and the rules aren’t always obvious.

Owners with multiple properties often fail to track income and expenses by property. Everything gets dumped into one account with no way to tell which rental is profitable. That adobe casita in town might be subsidizing a money-losing cabin in the mountains, but without property-level tracking you’d never know.

New Mexico adds another layer with Gross Receipts Tax. Short-term rentals are subject to GRT, and many owners don’t realize this until they get a letter from the Taxation and Revenue Department. Filing GRT returns monthly or quarterly is required, and the penalties for non-filing add up quickly.

Missing smaller deductions is common too. Supplies left for guests, mileage driving to the property, management software subscriptions, photography for your listing. These aren’t large individually but they add up over a year. Without a system to capture them, you’re paying taxes on income you didn’t really keep.

The fix for most of these mistakes is straightforward: use dedicated accounts for rental activity, reconcile platform reports monthly, and track expenses by property from day one. Clean books make tax time simpler and help you understand whether your rental is actually making money.
