A Question That Keeps Many Up at Night
You bought a second home. Maybe it was a quiet retreat tucked in the hills of Texas. Maybe it’s a home your children will inherit one day. Maybe it was for your parents, or your siblings, or to honor the memory of someone you love.
It might have been paid in full. Or maybe you took out a small mortgage, but your goal was simple: create a safe space, a long-term investment, a place that meant something. Not a business. Not a rental empire. Just something steady. Something personal.
And yet, here you are. You’re asking questions you didn’t anticipate:
- “Can I write off any of the expenses?”
- “Is it considered a rental even if I don’t charge rent?”
- “What does the IRS even mean by ‘personal use’ versus ‘rental use’?”
It can feel like the rules are built for someone else. Someone less generous. Someone more transactional. You’re not trying to exploit the system, you just want to do the right thing and not get blindsided in the process.
You’re not alone.
Why So Many Get This Wrong And Why It Matters Now More Than Ever
At Insogna, we’ve seen this situation unfold more times than we can count. A family buys a second home for a loved one. Or they rent it out occasionally. Or they just leave it empty, with plans for later. Either way, they walk into tax season with assumptions and those assumptions often clash with how the IRS sees things.
Why? Because the IRS doesn’t look at your second home through the lens of generosity or intent. It looks at structure, documentation, and financial behavior.
And without the right structure, your second home could be classified in a way that not only denies you potential tax deductions, but may even trigger penalties if deductions are claimed incorrectly.
This isn’t about trying to “game” the system. This is about understanding it deeply enough to honor your values while protecting your finances.
The IRS View: Personal Use vs. Rental Use Defined
To the IRS, a property must follow clear, consistent rules in order to qualify as a rental for tax purposes. That means:
- A formal lease agreement is in place.
- The tenant pays fair market rent
- You keep records of all payments and expenses.
- Your own personal use of the property is minimal and tracked.
If these elements aren’t in place, the IRS defaults to treating your second home as personal-use property. That means most of the deductions that would normally be available to a rental property like depreciation, maintenance, and utilities are no longer available.
And here’s the real twist: if you do deduct those expenses but don’t meet the IRS requirements, you may be required to pay them back later, often with interest and penalties.
The message is clear. If you want your second home to be considered a rental property in the eyes of the IRS, you have to act like a landlord even when you’re renting to someone you love.
A Real Story: Love, Legacy, and a Missed Opportunity
Let me share a story. Not to scare you but to show you how easy this mistake is to make.
A client we’ll call Laura bought a small cottage in Dripping Springs. She had no plans to rent it out on Airbnb. No dreams of becoming a real estate mogul. She just wanted her sister, who was going through a divorce, to have a place to stay while she got back on her feet.
Laura paid the taxes. She maintained the property. She even paid for internet and lawn care. So when tax time came, she assumed she could deduct at least some of those costs. After all, the home was being used and she was the one footing the bill.
But there was no lease. No rent. No written agreement. Just a quiet understanding between siblings.
The IRS saw that as personal use. And when Laura submitted her taxes, listing deductions for repairs and depreciation, the red flags were raised. A year later, she received a letter. Then a fine. Then the realization that her generous act had become a financial mess.
Laura didn’t do anything unethical. She didn’t cut corners or try to cheat the system. She simply didn’t know.
That’s why we’re here to help you know.
The Good News: Structure Creates Safety
Let’s walk through what the IRS actually wants to see. If you want your second home to qualify for rental tax treatment, here’s what you need:
1. A Formal Lease Agreement
Even if your tenant is a family member, you need a lease in writing. This should include:
- The full names of landlord and tenant
- The monthly rent amount
- Start and end dates
- Payment due dates
- Any included utilities or services
- Responsibilities for maintenance and repairs
This isn’t just paperwork. It’s evidence of intent. It shows the IRS that you’re treating the arrangement as a business transaction, not as a favor.
Your certified public accountant or a trusted legal resource can help you draft a lease that meets local and federal requirements.
2. Charging Market-Rate Rent
This is where many people trip up. They want to help someone, so they offer the home at a steep discount or no rent at all.
That’s a beautiful thing, but it doesn’t qualify for rental treatment.
To meet IRS standards, you must charge what the market would support. If homes in your area rent for $1,500/month, and you’re charging $200, that will likely be reclassified as personal use.
You can find market rents by:
- Checking local rental listings
- Using online tools like Rentometer or Zillow
- Asking a property manager for an estimate
Be sure to document your research, so you can back up your rental rate if ever questioned.
3. Consistent, Documented Payments
Once you set the rent, it must actually be paid and paid in a traceable, consistent manner.
- Avoid cash.
- Use checks, bank transfers, or online payment platforms.
- Keep records of every payment, and track any late or missed ones.
The goal isn’t just to collect money. It’s to show that the home is being operated like a real rental.
If rent isn’t paid, or is inconsistent, the IRS may challenge the entire arrangement.
4. Track Your Personal Use
You’re allowed to use your second home personally but only to a point.
Here’s the rule: you can use the home for up to 14 days per year OR 10% of the total days it’s rented at fair market value whichever is greater.
If you use it more than that, it becomes a personal residence in the eyes of the IRS, and your deductions become limited or disallowed.
That means vacations, holidays, or quick weekend getaways all count. Even if the home is empty, personal use still counts against the limit.
Keep a calendar or log of all usage: who was there, when, and for how long. It may feel tedious, but it’s a small act of protection for your peace of mind.
5. Track and Categorize All Expenses
Once your second home is structured properly, you can begin claiming appropriate deductions:
- Property taxes
- Mortgage interest
- Insurance premiums
- Utilities (if you pay them)
- Repairs and maintenance
- Professional fees (property manager, accountant)
- Depreciation over time
Having a clear record of income and expenses doesn’t just help at tax time, it helps you understand how your asset is performing over time.
And if you ever face an audit? You’ll have the receipts, literally.
Why This Matters: The Bigger Picture
At Insogna, we don’t just prepare taxes. We partner with people who want to make confident decisions, who care deeply about doing things right, and who often carry more emotional weight into their finances than they realize.
We understand that second homes are emotional. They’re about family, memory, future planning. They’re not just line items. They’re love letters.
That’s why we bring both precision and compassion to the conversation.
When you structure your second home with intention, you aren’t giving up your values. You’re protecting them. You’re creating a safe space for generosity and legacy to coexist with clarity and compliance.
Questions You Might Still Be Wondering
Can I switch how the home is used later?
Yes. A second home can transition between personal and rental use. But it must be tracked carefully. A property rented part of the year and used personally another part must allocate deductions proportionally.
What if I missed this in past years?
You’re not alone. It’s common. We can help you amend past returns if needed and create a strategy going forward. What matters is starting now.
What if the home is abroad?
Then FBAR filing requirements may apply. We’ll help you determine if your foreign property is subject to reporting and structure it properly to avoid steep penalties.
