Let’s start with a bold one: What if the IRS is eating better off your rental property than you are?
You think I’m kidding? I wish I were. Because here’s what happens to a lot of smart, hardworking rental property owners (maybe even you): you do all the right things. You set up the lease, collect the rent, call the plumber, repaint the bathroom, respond to a 10 p.m. “the thermostat isn’t working” text without losing your mind, and when tax season rolls around, you still feel like you’re flying blind.
And then, you file your return. And it hits you. That bill feels high. Higher than it should be.
That’s when the mind-shocker comes. You missed deductions. Not because they weren’t real. Not because they weren’t legit. But because they were hidden in plain sight. Quiet, subtle, not-obvious write-offs that you were fully entitled to if only you knew where to look or how to document them.
Let’s change that today.
Whether you own one long-term rental or you’re building your mini empire on Airbnb, the deductions I’m about to lay out can make or break your profit margin. Because yes, being a landlord comes with a lot of responsibilities. But it should also come with every single tax break you’ve earned.
Here are five of the most commonly missed deductions for rental property owners, how to capture them without triggering IRS confusion, and how to stop leaving money on the table just because tax rules read like they were written by someone with a grudge against plain English.
1. Your Cell Phone and Internet (Yes, You Can)
Let’s talk about your phone. Not metaphorically. Literally.
If you’ve ever called a tenant, texted your handyman, replied to a booking inquiry on VRBO, or reviewed an inspection report while waiting in line for coffee, that phone use counts.
And guess what? So does your Wi-Fi if you’re using it to:
- Pay property-related bills
- Log maintenance requests
- Manage listings
- Check in on your property manager
- Review your rental income spreadsheet
Here’s where it gets technical but in the fun way.
You can’t deduct 100% of your cell or internet bill unless you use it solely for the rental (and let’s be real: unless you bought a burner phone just for tenants, you don’t).
But you can deduct the percentage of business use. That means if 20% of your usage is for rental management, 20% of your annual bill is deductible.
Aha moment: That “small” percentage adds up. Let’s say your cell and internet bills are $2,400 a year. That’s a $480 deduction you’re probably not claiming.
Real-world tip: Keep a one-month log of all business use (calls, texts, emails, portals) and let that sample support your deduction ratio.
How to keep it clean: A certified public accountant near you can help you document this properly and avoid over-claiming. No guessing. No hoping. Just clarity.
2. Your Home Office (The IRS Is Not Coming for You)
No, the IRS isn’t going to kick down your door just because you claimed a home office.
That rumor is as old as the paper file cabinet in your attic.
Here’s the real story: If you have a space in your home used exclusively and regularly to manage your rental property, you may be entitled to a home office deduction.
This applies whether your property is next door or two time zones away. What matters is where the work happens.
That work might include:
- Reviewing lease agreements
- Scheduling repairs
- Posting listings
- Logging income and expenses
- Coordinating with your Austin tax accountant about next year’s return (had to get that one in there)
But don’t get cute. The corner of your kitchen table doesn’t count if it doubles as your breakfast nook.
To qualify:
- The space must be used only for rental activity.
- You need to use it regularly not just once a month when inspiration strikes.
- You must manage your property yourself (not fully outsourced).
You can deduct a portion of:
- Mortgage interest or rent
- Utilities
- Insurance
- Repairs to the home office area
- Depreciation (if you own the home)
Aha moment: Even if the rental is miles away, your home office still counts as your “main place of business” for the rental, as long as it’s where you handle the back-end operations.
And here’s the kicker: A licensed CPA can help you decide between the simplified method (flat $5/sq. ft.) or actual expense method to get the most bang for your square footage.
3. Travel and Mileage: The Deduction That Gets Overlooked Every Time
If you’ve ever driven to check on your property, pick up supplies, meet a contractor, or simply ensure your tenants haven’t turned your investment into a frat house… and didn’t track your mileage?
You’re missing a deduction that’s basically paying for your gas.
Every mile driven for rental-related activity is deductible. In 2025, that’s 70 cents per mile. Ten trips across town might not feel like much until you realize that’s potentially hundreds of dollars in deductions just disappearing into thin air.
Also deductible:
- Parking fees
- Tolls
- Uber or Lyft to and from the property
- Airfare and lodging if managing an out-of-town rental
Caution: If the trip is personal with a rental stop tacked on, you’re only deducting the business portion. A quick “while I’m in the area” visit doesn’t magically convert vacation into a tax write-off.
How to track it: Mileage apps like MileIQ or QuickBooks Self-Employed are great. Old-school logs work too if you actually keep them.
Need help deciding what counts? A tax advisor near you can walk you through the grey areas so you’re not guessing. At Insogna, we set our clients up with systems that turn this from “meh” to money in the bank.
4. Depreciation: The Heavyweight Deduction Most People Forget
Let’s have a heart-to-heart about depreciation.
It is, hands down, the most powerful deduction for rental property owners and the one that gets forgotten the most.
Why? Because it’s sneaky.
You don’t spend any money this year. You don’t get a receipt. It’s not tied to a bill or a service. But every year you own your rental, the IRS lets you deduct a portion of the building’s value because it’s wearing out (in theory).
Here’s how it works:
- You buy a rental property for $300,000
- The land is worth $50,000
- The building (depreciable asset) is worth $250,000
- IRS depreciation schedule = 27.5 years
- That gives you $9,090/year in depreciation deductions
That’s $9,090 you deduct without spending another dime.
Mind-shocker moment: If you forget to claim depreciation, not only do you miss the deduction, but when you sell, the IRS will still assume you did and tax you on it. It’s called depreciation recapture, and it’s not as fun as it sounds.
This deduction alone is why every rental owner should have a tax accountant near them who can create a depreciation schedule, track improvements, and keep the math clean.
Because this isn’t just about deducting now, it’s about protecting yourself later.
5. Personal Use vs. Rental Use (Don’t Let the Calendar Cost You)
If you use your rental property for personal enjoyment at all, it can affect how much you can deduct.
Quick breakdown:
- Rent it out more than 14 days and use it personally less than 14 days (or less than 10% of total rental days)? You’re golden. Deduct away.
- Use it for personal reasons more than 14 days or 10% of rental use? Now you’re in vacation home territory and deductions get limited.
- Rent it 14 days or fewer per year and use it personally the rest of the time? Congrats, you don’t report the rental income but you also can’t deduct the expenses.
This is where tracking matters. A day or two can swing your property from tax-efficient rental to limited-deduction vacation home.
Keep a log. Yes, like a literal calendar. Who was in the property, for how long, and for what purpose. A certified professional accountant can help you apply these rules so you don’t get surprised later.
The Hidden Message Behind These Deductions
You didn’t get into rental property to become a tax expert.
You got into it for passive income. For long-term growth. For the vision of wealth that builds while you sleep or at least while someone else unclogs the drain.
But here’s the real truth: None of that works as well as it should if your tax strategy isn’t working with you.
If you’re missing deductions because you didn’t know to look, or if you’re not confident in your systems, or if you’re hoping the IRS will overlook your handwritten mileage log from 2020… it’s time to rethink your approach.

Frequently Asked Questions
1. Can I deduct part of my phone and internet bills for managing my rental?
Absolutely, if you’re using your phone or Wi-Fi to handle tenant calls, schedule repairs, check bookings, or manage rent payments, that counts as business use. The IRS lets you deduct the business-use percentage of these expenses. Just track it.
Need help calculating the right percentage (without making it up)? That’s what a certified public accountant near you is for. At Insogna, we help you document it the right way and make it stick in an audit.
2. I manage my rental from home. Can I claim a home office deduction?
If you have a dedicated space in your home used exclusively and regularly to manage your rental then yes, you probably can. And no, the IRS isn’t waiting to slap your hand for it.
Just make sure it’s not the dining table or the couch. It has to be used only for your rental-related work.
Not sure if your setup qualifies? A quick chat with a tax advisor near you or an Austin, TX accountant can help you nail it down.
3. I drive to my rental a few times a year, c I deduct mileage?
Yes, and you should. Whether you’re checking on the property, picking up supplies, meeting a contractor, or dropping off keys, mileage adds up fast. The 2024 IRS mileage rate is 70 cents per mile. That’s real money.
Keep a log. Track your trips. Don’t wait until tax season to guess. A licensed CPA can set you up with a system that makes it easy.
4. What is depreciation, and why do rental owners always forget it?
Depreciation is the IRS’s way of letting you deduct the cost of your rental property’s structure over 27.5 years. It’s a major deduction (thousands per year) and it doesn’t require you to spend more money.
But here’s the kicker: If you don’t claim it, the IRS might tax you as if you did when you sell. Ouch.
Don’t skip this one. Work with a tax preparation service near you or a certified CPA in Austin, Texas to get your depreciation schedule set up correctly.
5. Does using my rental for personal vacations impact my deductions?
You bet it does. If you use the property personally more than 14 days per year, or more than 10% of the days it’s rented, you’re in vacation home territory. That means limited deductions and extra IRS rules.
Track your days. Every single one. A few too many family weekends could cost you thousands in write-offs.
Want help navigating the IRS vacation rules? That’s what a tax consultant near you or small business CPA in Austin is trained to do.
