Renting out a room in your home can be a great way to generate additional income, help offset rising living costs, or make better use of unused space. However, many homeowners are surprised to learn that renting part of a personal residence comes with its own set of tax rules and reporting requirements.
Unlike owning a separate rental property, renting out a room in your primary residence creates a mixed-use situation. The home is considered both personal and rental property at the same time, which means many expenses must be divided between personal and rental use.
In most cases, the rental income you receive must be reported on your tax return. The good news is that you may also be able to deduct a portion of eligible household expenses connected to the rental activity.
Common deductible expenses may include a portion of:
- Mortgage interest
- Property taxes
- Utilities
- Internet and Wi-Fi
- Homeowners insurance
- HOA dues
- Repairs and maintenance
- Cleaning expenses
- Depreciation
The percentage you can deduct is usually based on the portion of the home being rented. This often starts with square footage calculations, but shared living spaces may also factor into a reasonable allocation method depending on the situation.
For example, if a tenant rents one bedroom but also uses the kitchen, bathroom, laundry room, and living room, the deductible percentage may be higher than just the square footage of the bedroom alone. The allocation should be reasonable, supportable, and consistently applied.
Repairs are also treated differently depending on who benefits from the expense.
Generally:
- Repairs only affecting the rented room may be fully deductible.
- Repairs benefiting the entire home are usually prorated.
- Personal household expenses remain non-deductible.
For example, repainting the tenant’s room may qualify as a full rental expense, while replacing the home’s water heater would generally be split between personal and rental use.
Depreciation is another important factor many homeowners overlook. The IRS may allow you to depreciate the rental-use portion of the home over time, which can reduce taxable rental income. However, depreciation claimed during the rental period may affect taxes when the home is eventually sold.
Short-term rentals through platforms like Airbnb or VRBO can create additional considerations depending on how often the room is rented and what services are provided to guests.
Good recordkeeping is extremely important when renting part of your home.
Homeowners should maintain organized records of:
- Rental income received
- Lease agreements
- Square footage calculations
- Utility bills
- Repair invoices
- Improvement costs
- Dates the room was rented
- Shared expense calculations
Many taxpayers accidentally overclaim deductions or fail to properly allocate expenses between personal and rental use. Keeping clear documentation throughout the year can help avoid problems later and make tax preparation much smoother.
Renting out a room can absolutely provide legitimate tax benefits, but understanding the rules ahead of time helps ensure those deductions are handled correctly.
