Rental Property Tax Deductions Every Landlord Should Know

If you own a rental property, the IRS is going to write you some big checks this year. You probably won't see them the way you see a paycheck, but they're real and they're big. I'm Matthew Whitaker, founder of Evernest and author of How to Rent Your Home. There are six different ways the tax code rewards you for owning a rental, and three traps that catch first-time landlords every single year. Here's all nine, in plain English, with the math on each one.

The short version

The short version: Rental owners get six real tax breaks: depreciation, mortgage interest, operating expenses, travel and home office deductions, cost segregation, and the QBI deduction. Depreciation alone can turn a $300,000 rental into $8,700 a year in paper losses. But three traps catch first-time landlords: passive loss limits, depreciation recapture when you sell, and self-rental rules if you rent to your own business. Know all nine before you talk to your CPA.

Depreciation: the biggest tax break for landlords

Depreciation is the single biggest reason rentals are tax-friendly, and it works even while your property is going up in value.

Here's the idea. The IRS pretends your rental house is slowly wearing out over 27.5 years, even though the house is probably appreciating, not depreciating. The IRS lets you act like it's losing value on paper, and that paper loss reduces your taxable income, which means you pay less in taxes.

The math: take what you paid for the building only (the land doesn't count, since land doesn't wear out), then divide that number by 27.5. That's your depreciation each year. On a $300,000 rental, the building itself is worth about $240,000. Divide that by 27.5 years and you get $8,700 in paper losses every year. If you're in a 30% tax bracket, that turns into about $2,500 in real tax savings. You didn't spend that money. You just got it.

Mortgage interest and operating expenses

Every dollar of interest you pay on your rental's mortgage counts as a business expense, and business expenses reduce your taxable income.

In year one of a 30-year loan, almost all of your monthly payment goes toward interest. On a $225,000 loan at 7%, that's about $15,500 in interest in year one, and all of it is deductible. This is one of the reasons rentals often look like they're losing money on paper in their early years, while actually doing fine.

Beyond interest, every dollar you spend running the property is deductible too:

Maintenance and repairs.
Property management fees.
HOA dues.
Utilities you pay.
Insurance and property taxes.
Marketing your listing.
Legal fees.

If you spend $100 on a repair and forget to deduct it, you just lost about $30 in real tax savings. Track everything. A separate bank account for your rental isn't optional. It's the only way to catch every expense at tax time.

Travel, home office, and cost segregation

If you drive to the rental to inspect it, fix something, meet a contractor, or handle a tenant issue, that's a business trip, and you can deduct the mileage. If you fly somewhere because the rental is out of state, you can deduct the airfare and the hotel. You can also deduct a piece of your home if you have a dedicated space where you manage the rental.

The catch is documentation. Keep a log. If you can't prove which trip was business and which trip was vacation, you'll lose the deduction in an audit.

The more advanced move is cost segregation. Remember depreciation, where the IRS lets you take a loss spread over 27.5 years? Cost segregation breaks the building down into smaller pieces, like the appliances, the flooring, and specific systems, and lets you depreciate those pieces faster, some over 5 years and some over 15. The total deduction ends up the same, but you get most of it in the early years when you need it most.

For a $300,000 rental, cost segregation can move $30,000 to $60,000 of paper losses into your first 5 years of ownership. For a high-income earner, that's $5,000 to $15,000 in real tax savings in year one alone. The catch: a formal cost segregation study costs $2,000 to $5,000 to do properly, so it only makes sense on properties valued at $200,000 and up, where the savings clearly beat the study costs. Talk to your CPA before you spend the money.

The QBI deduction

QBI stands for qualified business income. In plain English, if the IRS treats your rental like a real business, you can deduct an extra 20% of your rental's income right off the top. That's a big deal.

To qualify, you usually need to be actively involved in managing the property, and the rules are technical. This is exactly the kind of thing to bring up with your CPA, but if you qualify, the savings are significant.

Three tax traps that catch first-time landlords

The tax code also has three traps that surprise landlords who aren't expecting them.

Passive loss limits. The IRS sorts your income into two buckets: active income (your salary, bonus, or income from a business you actually run) and passive income (rental income, mostly). Paper losses from your rental, especially depreciation, can generally only cancel out other passive income. They shelter the rental's own income, but they can't reduce the tax you owe on your day job. There's one exception: if you make less than $100,000 a year, you can deduct up to $25,000 of those losses against your salary. That deduction shrinks between $100,000 and $150,000 in income, and above $150,000, the losses get stored away until you have more passive income or until you sell the property.
Depreciation recapture. This is the bill that comes due when you sell. All those years you used depreciation to pay less in tax, the IRS wants some of that money back when you sell, and it's taxed at 25% on every dollar of depreciation you claimed while you owned the property. If you claimed $87,000 in depreciation over 10 years, you could owe up to $21,750 in recapture tax when you sell. A 1031 exchange can defer that tax: if you trade your rental for another rental, recapture gets pushed off to the next sale. That's one of the biggest reasons 1031 exchanges are popular with portfolio builders.
Self-rental rules. This one catches business owners. Say you own a small business and a building, and you decide to rent that building to your own business. Sounds smart, since you're paying yourself rent instead of a stranger. But the IRS has special rules for this exact scenario: the income gets treated as active income, while losses get treated as passive losses, which means they can't offset other active income. It's a one-way street. You eat the income, but you can't easily use the losses.

Quick recap

Depreciation. Roughly $8,700 a year in paper losses on a $300,000 rental.
Mortgage interest. Nearly all of your year-one payment on a new loan.
Operating expenses. Maintenance, management fees, HOA dues, utilities, insurance, taxes, marketing, and legal fees.
Travel and home office. Mileage, airfare, hotel, and a portion of your home office, if documented.
Cost segregation. Front-loads depreciation for properties at $200,000 and up.
QBI deduction. An extra 20% off your rental income, if you qualify.
Passive loss limits. Losses generally offset only passive income, with a partial exception under $150,000 in income.
Depreciation recapture. A 25% tax on claimed depreciation when you sell, deferrable with a 1031 exchange.
Self-rental rules. Income counts as active, losses count as passive, if you rent to your own business.

Frequently asked questions

How does rental property depreciation work?The IRS lets you treat your rental building (not the land) as if it's wearing out over 27.5 years, even if it's actually appreciating. Divide the building's value by 27.5 to get your annual depreciation. On a $300,000 rental with a $240,000 building value, that's $8,700 a year in paper losses, worth about $2,500 in real tax savings at a 30% tax bracket.

Can I deduct mortgage interest on a rental property?Yes. Every dollar of interest you pay on your rental's mortgage counts as a deductible business expense. In year one of a 30-year loan, almost all of your payment goes to interest, so on a $225,000 loan at 7%, you could deduct roughly $15,500 in year one alone.

What rental property expenses can I write off?Every dollar you spend running the property is deductible: maintenance, repairs, property management fees, HOA dues, utilities you pay, insurance, property taxes, marketing, and legal fees. Keep a separate bank account for the rental so you catch every expense. Missing a $100 deduction costs you about $30 in real tax savings.

Can I deduct travel expenses for managing my rental?Yes, if it's a genuine business trip: driving to inspect the property, make a repair, meet a contractor, or handle a tenant issue lets you deduct mileage, and flying to an out-of-state rental lets you deduct airfare and lodging. You can also deduct a dedicated home office space. Keep a log, since you need to prove business trips versus personal trips in an audit.

Is cost segregation worth it for a rental property?It depends on the property value. Cost segregation breaks a building into components (appliances, flooring, systems) that depreciate faster than the standard 27.5 years, moving $30,000 to $60,000 of paper losses into your first 5 years on a $300,000 rental. But a formal study costs $2,000 to $5,000, so it typically only pays off on properties valued at $200,000 and up.

Can I deduct rental property losses against my regular income?Usually not fully. Rental losses are passive losses and generally only offset other passive income, not your salary. If you earn less than $100,000 a year, you can deduct up to $25,000 of losses against your salary, phasing out between $100,000 and $150,000. Above $150,000, losses carry forward until you have passive income or sell.

What is depreciation recapture and how much will I owe when I sell?When you sell, the IRS taxes back the depreciation you claimed over the years at a 25% rate. Claim $87,000 in depreciation over 10 years, for example, and you could owe up to $21,750 in recapture tax at sale. A 1031 exchange, trading your rental for another rental property, can defer that tax to the next sale.
