Renting a room to a family member is generally taxable income if you charge fair market rent, and it must be reported to the IRS. If you charge below-market rent, the IRS may classify it as personal use, making the income non-taxable but disallowing expense deductions. "Cost-sharing" (e.g., splitting utilities) is typically not taxable.
Consequently, you must report all rental income, but you cannot deduct any rental expenses except for mortgage interest and property taxes, which are deductible for personal residences. Good-Tenant Discount: The IRS allows a modest discount (up to 10%) on the fair market rent under the good-tenant clause.
If you're part of a homeowner association (HOA), you'll need to ensure that renting is allowed under the community's rules. Certain HOA restrictions include only renting a room in your house to a family member. Always research local laws before renting.
Many people earn extra money by renting out a room in their home. As far as taxes go, this comes with bad news and good news: The bad news is that the rent you receive is taxable income that you must report to the IRS. (However, under the 14-day rule, rental income for less than 15 days per year isn't taxable.)
For 2024 and 2025 income, a business must send you a Form 1099-NEC if they paid you $600 or more for services as an independent contractor (nonemployee compensation); this threshold increases to $2,000 for 2026 and beyond, indexed for inflation, while other 1099s (like 1099-K for payment apps) have different rules, but you must report all self-employment income regardless of receiving a form.
It's legal to rent property to a relative, but there are tax implications to consider. If you're receiving rent from a family member, you may be liable to pay tax on that rental income.
The IRS knows about your rental income through data matching with third parties (like mortgage lenders, banks, property tax offices, payment apps) and public records (licenses, property deeds, rental listings), flagging discrepancies with your tax return via their Automated Underreporter Program, and sometimes through tips from whistleblowers, catching unreported income from sources like Form 1098, online platforms, and even state licensing records.
How To Rent Out A Room In Your House In 8 Steps
The IRS treats rental income from family members the same as income from other tenants, provided you charge fair market rent and formalize the arrangement. It considers the rent as taxable income, and you must report it on your tax return. Accurate documentation is critical to validate the income.
If you rent out a primary residence or vacation home in the US for 14 days or less a year, the rental income is typically tax-free under a rule commonly referred to as “The Augusta Rule” (or in IRS circles as Section 280A. Less catchy, we know).
Not reporting all of your income is an easy-to-avoid red flag that can lead to an audit. Taking excessive business tax deductions and mixing business and personal expenses can lead to an audit. The IRS mostly audits tax returns of those earning more than $200,000 and corporations with more than $10 million in assets.
Failure to Report
Money earned from real estate rental is taxable income, less any allowable deductions. Failing to report it on a tax return can accrue the same types of penalties and late-payment interest as any other underreported income. The penalties that a taxpayer-landlord accrues depend on their situation.
Even if you're renting to family, collecting rent is a form of income you must report on your taxes. The property is classified as a rental property if the owner uses it for personal reasons for less than 14 days or 10% of the tax year if rented at a fair market price.
You can rent out rooms in a single-family home if you are living there in most areas; if you are not living there, you will need to check your local restrictions to see if it is allowable to rent out the rooms individually.
Now that you own the home, you can rent it back to your Parents and have a rental property on your tax return. Courts have said that landlords can reduce their fair-market rent by 20% when renting to relatives. That lower rent reflects the savings in maintenance and management costs (L.A. Bindseil, TC Memo 1983-411).
For services performed in 2025 and prior, you get a 1099-NEC (or MISC) if you earn $600 or more from one business; starting in tax year 2026, that threshold increases to $2,000 for Form 1099-NEC and Form 1099-MISC, adjusted for inflation in later years, but you must always report all self-employment income, regardless of whether you receive a form.
