The questions to ask your accountant before tax time.
Most hosts never hear about the 14-day rule, how to split shared costs, or whether their rental counts as a business. These are the questions worth asking, by what you rent out.
Everyone who rents something out
Is this rental income or business income?
Short stays where you provide hotel-like services (cleaning during the stay, supplies, concierge) can be treated as a business, which usually means self-employment tax. Plain rentals usually aren’t. Ask which form yours belongs on.
What can I deduct, and how do I split shared costs?
Platform fees, cleaning, supplies and repairs are often deductible. Costs you share with personal use (utilities, insurance, upkeep) usually have to be split by how much the asset is rented. Ask how to split yours.
Will I get a 1099-K, and does it matter?
For 2026, platforms generally send a 1099-K once you pass $20,000 and 200 transactions. Your rental income is taxable either way; the form only reports it.
Do I owe local occupancy or sales tax?
Many cities charge a hotel-style tax on short stays. Airbnb collects it in many places, but not every platform does, and not for every kind of rental. Ask what applies in your city.
What records should I keep?
Income, fees and expenses for each asset, plus the dates it was rented versus used personally. Ask what format your accountant wants.
Vacation home
Does the 14-day rule apply to me?
If you rent your home for 14 days or fewer in a year, that income is generally not taxable, but you also can’t deduct rental expenses.
How do my personal-use days change things?
If you use the home yourself for more than 14 days, or more than 10% of the days it’s rented, the vacation-home rules can limit your deductions.
Does the short-term rental exception apply?
With an average stay of 7 days or less and enough personal involvement in running it, rental losses may be able to offset other income, such as a salary. This one is aggressive and depends heavily on your facts.
Should I be depreciating the home and furnishings?
Depreciation is often the biggest deduction for a rental home, and it has consequences when you sell.
Event space or studio
If the space is part of my home, how do I split costs?
Square footage and hours of use usually drive how much of rent, mortgage interest, utilities and insurance you can claim.
How should I handle equipment I rent out with the space?
Lights, grip, furniture and backdrops may be deducted all at once or over several years, depending on cost and how you use them.
Is this rental income or business income for me?
Hourly bookings with services (equipment, setup help, staff) are more likely to be treated as a business.
Does the 14-day rule apply if the space is in my home?
Occasional rentals of a home may fall under the 14-day rule. Ask whether yours qualifies.
Pool, hot tub, or sauna
Does renting only my pool count under the 14-day rule?
This isn’t settled. Some advisors treat hourly pool rentals as renting part of your home; others don’t. Ask before you count on it.
How much of my pool costs can I claim?
Chemicals, heating, water, cleaning and repairs are usually split by how much the pool is rented versus used by you.
Are guest upgrades deductible?
Things you buy mainly for guests (a heater, cabana, loungers, towels, a restroom upgrade) may be deductible or depreciable.
Do I need extra insurance, and is it deductible?
Many homeowners policies limit coverage for business use. A rider or separate policy may be needed and is usually a deductible cost.
Driveway, garage, or storage
Is small monthly income still taxable?
Yes, even if you never receive a 1099-K. Ask how to report it simply.
Can I claim any costs?
Usually small: a share of upkeep, security or insurance for the space, if any. Ask whether it’s worth tracking.
Could it affect my property tax or HOA rules?
Not usually a tax question, but worth checking with your HOA before you list.
Car, truck, or van
Mileage rate or actual expenses?
You can often choose between a standard mileage rate and actual costs (depreciation, insurance, repairs). The choice you make in the first year can lock you in later.
What’s my business-use percentage?
If you also drive the car personally, deductions are usually limited to the share of use that’s for the rental.
Will this count as a business?
Car sharing is often reported as business income, which usually means self-employment tax.
How is depreciation handled if I sell the car?
Deductions taken while renting can be partly taxed back when you sell. Ask how it applies to you.
Boat or yacht
How do my personal-use days affect deductions?
As with a vacation home, heavy personal use can limit what you can deduct.
What costs can I claim?
Dockage, maintenance, insurance, fuel and cleaning for charter use are often deductible, split between rental and personal use.
How should I handle captain and crew costs?
Whether you pay a captain directly or the renter does changes how the income and costs are reported.
Should I be depreciating the boat?
Depreciation can be significant, and it has consequences when you sell.
RV or camper
Does my RV count as a second home?
An RV with sleeping, cooking and toilet facilities can be treated like a vacation home, so your personal-use days may limit deductions.
What costs can I claim?
Insurance, storage, maintenance, cleaning, delivery and platform fees are often deductible, split between rental and personal use.
Should I be depreciating the RV?
Depreciation can be one of the biggest deductions, and it has consequences when you sell.
Is this rental income or business income for me?
Adding services like delivery and setup can make it look more like a business, which may mean self-employment tax.
