How Is Rental Income Taxed When You Have a Mortgage? 

Key Takeaways

• Rental income is taxable, regardless of whether you have a mortgage, and must be reported on Schedule E.
• You can reduce your taxable income with deductions for expenses like mortgage interest, property taxes, depreciation, and operating costs.
• Personal stays, short-term rental activity, or how long you’ve owned the home can all impact how much tax you owe and what breaks you might qualify for.

In 2024, nearly 10 million Americans reported owning rental property.

Whether you're renting full-time, seasonally, or just dipping a toe into the market, one thing is certain: the IRS expects you to report that income. Even if it feels like you’re just covering the mortgage or barely breaking even, rental earnings are still taxable.

The real question is how to report it and how to reduce what you owe. The good news is there are plenty of ways to ax your tax bill, especially if you run a short-term rental.

If you know what counts as income, which deductions apply, and how personal use affects your tax situation, you're in a better position to file with confidence. This guide covers how rental income is taxed, what you can deduct, and what to know if you use the property yourself or decide to sell.

Mortgage or Not, Here’s How the IRS Taxes Rental Income

Many first-time rental property owners wonder:

“If my rental income just barely covers the mortgage, and I’m not making any money, why do I owe taxes?”

Here’s the key: The IRS doesn’t tax profit. It taxes income.

Even if every rent check goes straight to your mortgage lender, that rent still counts as taxable income. The IRS doesn’t consider how you spend the money. It only looks at how much money you receive.

That can feel frustrating, especially if your rental isn’t generating extra cash. However, you’re not stuck paying tax on the full rental amount. You can deduct eligible expenses to reduce your taxable income. These typically include:

• Mortgage interest
• Property taxes and insurance
• Repairs, maintenance, and utilities
• Depreciation of the property
• Travel and professional fees related to the rental

These deductions help you calculate net rental income, which is the number the IRS actually taxes you on. In some cases, especially early on, you may even show a loss on paper, meaning you won’t owe any tax and might even use that loss to offset other income, depending on your situation.

The bottom line is that even if your rental "breaks even" or feels like it’s running at a loss, it can still have tax implications. You must keep detailed records and understand how deductions work in order to minimize what you owe.

How to Calculate Taxable Rental Income 

Once you understand how rental income is taxed and what deductions you can take, the next step is figuring out how much income you're actually working with. That number will help you estimate your potential tax bill, determine if you need to make estimated payments, and understand what tax bracket your rental earnings might push you into.

How you calculate that income depends on the type of property you own.

Long-term rentals tend to be simpler. You likely have a fixed monthly rent and steady occupancy, which makes it easier to project your annual income and expenses.

Short-term rentals, on the other hand, are much more variable. Nightly rates change, bookings fluctuate with the seasons, and personal use can reduce the number of nights you're earning income. Because of that, STR hosts typically estimate their taxable income in one of two ways:

1. Estimate your short-term rental income manually

One of the simplest ways STR hosts estimate income is with a back-of-the-napkin equation:

Average Daily Rate (ADR) × Occupancy Rate × 365

This gives you a rough projection of annual gross revenue.

Using our data from Jackson Hole as an example: if the average occupancy rate is 61% and the average daily rate is $557.97, you'll multiply 557.97 x .61 x 365 for an estimate of $124,232.02 in total annual rental income.

Keep in mind that this formula is based on market averages and assumes your property is available year-round. The calculation doesn’t factor in personal use, seasonal fluctuations, or off-market days for maintenance. If your calendar isn’t fully open or your booking patterns shift throughout the year, this estimate could be higher than what you’ll actually earn.

Still, it’s a helpful baseline, especially when you’re looking at how much money you can make with Airbnb in a specific market. 

2. Estimate income with a vacation rental calculator

Crunching the numbers on your own won’t always account for unexpected shifts in supply or demand that affect your rental income. An Airbnb calculator can offer extremely accurate revenue estimates by:

• Analyzing nearby properties
• Creating an index based on relevance
• Integrating critical market metrics like seasonality and occupancy
• Comparing your property to similar listings

It'll then project the total annual rental income based on the real performance of similar properties. You can use that estimate to calculate rental income tax for any given tax year. If we look at an actual for-sale property in Jackson Hole, Wyoming, we can see that property-specific revenue estimates can differ significantly from market averages. This 5-bed, 5-bath home, for instance, is projected to earn just shy of $163,000 per year.

How to Report Rental Income Step-by-Step

You’ll report your rental income and expenses using Schedule E (Form 1040). Here’s how to do it in a few straightforward steps:

Gather all rental income

This includes more than just rent. Add up all payments you’ve received from guests, like cleaning fees, pet charges, and nonrefundable deposits.

Track your expenses

Deductible expenses may include mortgage interest, property taxes, insurance, maintenance, utilities, and depreciation. Keep receipts and statements for each one.

Fill out Schedule E

List your income and expenses on Schedule E to calculate your net rental income (the amount the IRS will tax).

Keep detailed records

Accurate documentation is key, especially if you're ever audited. A tax professional can help you determine how your rental is classified and make sure you're maximizing your deductions.

Determine if you need to make estimated tax payments

If you expect to owe $1,000 or more in taxes for the year (after withholding), the IRS may require you to make estimated payments throughout the year. This can be done quarterly, or you can adjust your W-2 withholding to account for the rental income.

See if you qualify you for a bigger tax break

Most rental income is considered passive, which means any losses can usually only offset other passive income. Short-term rentals have an edge in this department. 

If your average guest stay is seven days or less, and you provide substantial services (like guest communication, cleaning between stays, or stocked amenities), the IRS may consider your rental activity active. That could allow you to deduct rental losses against other income, like W-2 wages or business income.

Not every host will qualify, but if your STR is more hands-on, it’s worth checking with a tax advisor. You might be able to unlock a more favorable tax position just by how your activity is classified.

Mortgage and Tax Deductions for Rentals

When you file your taxes, you’ll choose between taking the standard deduction or itemizing your deductions. The standard deduction is a flat amount that most taxpayers subtract from their income. It’s simple and doesn’t require you to list individual expenses. For many people, it’s the easiest and most beneficial option.

However, if you own a rental property, itemizing could lower your taxable income even more. That’s because rental property owners can often deduct a wide range of operating expenses, and those deductions can add up quickly, especially if you have a mortgage or actively manage the property.

Here are some of the most common expenses that the IRS allows rental property owners to deduct:

• Mortgage interest
• Property taxes
• Operating costs
• Travel expenses
• Home office use
• Professional services
• Advertising and listing fees
• Insurance
• Depreciation

There's one thing you have to get right before claiming any deductions: documentation. If you get audited, the IRS will need a paper trail for every item you deduct. Save all receipts, mortgage statements, property tax bills, and invoices so you can verify your rental expenses if the IRS asks.

Depreciation deductions for rental property

Depreciation lets you deduct part of your property’s value each year to account for wear and tear over time. You can start claiming it as soon as the property is available to rent—even if it hasn’t had its first booking yet.

To qualify, your rental must:

• Be owned by you
• Be used to generate income
• Have a useful life of more than one year
• Wear out or lose value over time

If it meets those criteria, you can typically deduct 3.636% of the building’s value each year over a 27.5-year schedule. This non-cash deduction can make a big difference in lowering your taxable rental income over time.

Tax Effects of Personal Property Use

If you use your rental property for personal stays, even for just a few days, it can change how the IRS treats your income and what deductions you’re allowed to claim.

The IRS considers your property mixed-use if it's used for personal purposes for more than 14 days in a year, or for more than 10% of the total days it’s rented at fair market value—whichever is greater. Once your property crosses that threshold, it’s no longer treated purely as a rental.

That change affects your deductions. You’ll need to split your expenses between personal and rental use, and only deduct the portion tied to rental activity. For example, if you stay there 20 days and rent it for 180, you can deduct about 90% of eligible deductible expenses (like the ones we went through earlier). 

Personal-use days don’t count toward those deductions, even if you're doing small repairs or cleaning.

If you rent the property occasionally but use it mostly for personal reasons, the IRS may classify it as a second home. You’ll still need to report any rental income, but most rental deductions will be off-limits, including the ability to deduct rental losses.

On the other hand, if your personal use stays below the threshold, your property is treated as a rental. You can deduct the full share of eligible expenses and, depending on your income, possibly up to $25,000 in rental losses against other types of income. That benefit phases out once your modified adjusted gross income (MAGI) exceeds $100,000.

Ultimately, the more you use your rental personally, the more restricted your tax benefits become. Tracking rental vs. personal-use days is key to filing correctly and maximizing your deductions.

Taxes When Selling a Mortgaged Rental

Selling a rental property can trigger several different taxes, depending on how long you’ve owned it, how you’ve used it, and how much profit you’ve made. If the property has appreciated in value, here are the most common taxes you may face.

Taxes you may owe when you sell

Capital gains tax

This is the most common tax investors encounter when selling a rental. Your capital gain is the difference between the sale price and your adjusted cost basis, which typically includes your purchase price plus improvements and minus depreciation.

• If you owned the property for less than one year, the gain is taxed at your ordinary income rate.
• If you owned it for more than one year, it’s taxed at a lower long‑term capital gains rate.

Depreciation recapture

If you claimed depreciation while owning the property, the IRS may require you to pay some of that tax benefit back when you sell. This portion of your gain is typically taxed at up to 25%, even if your capital gains rate is lower.

Net investment income tax (NIIT)

If your income exceeds certain thresholds, you may also owe an additional 3.8% NIIT on your net investment income, including capital gains from a rental sale.

Ways to reduce or defer taxes when you sell

In some cases, you may be able to reduce or delay the taxes triggered by a sale.

1031 exchange

Also called a tax‑deferred exchange, this strategy allows you to reinvest the sale proceeds into another qualifying investment property within a specific time frame. If done correctly, you may be able to defer both capital gains tax and depreciation recapture.

Primary residence exclusion

If the property was your primary residence for at least two of the last five years, you may be eligible to exclude up to $250,000 of capital gains ($500,000 for married couples filing jointly). Special rules apply if the home was also used as a rental, including short‑term rentals.

Tax Planning for Rental Investments

Short-term rental investing has a lot of silver linings, but there's also plenty of red tape. 

While we’ve covered how rental income is taxed when you have a mortgage, it’s still a good idea to talk with a tax professional. State rules can vary, and your filing options may depend on how you use the property or what deductions you qualify for.

Knowing your tax liability before you invest is key, but so is understanding your earning potential. The better you can forecast your revenue, the easier it is to decide whether the tax bill is worth it.

FAQs

What qualifies as rental income?

Rental income includes more than just monthly rent payments. The IRS considers things like nonrefundable deposits, pet fees, cleaning fees, and cancellation charges as rental income and requires them to be reported.

Do I have to pay taxes on a room I rent in my house?

Yes. Even if you’re only renting part of your home (like a basement or spare bedroom), the income is still taxable. You can deduct expenses proportionally (based on square footage or use) if the space is used exclusively as a rental.

What if I only rent my property for a few weeks?

If you rent your home for 14 days or fewer per year, and use it yourself the rest of the time, you generally don’t have to report that income at all. This is sometimes called the “Masters exemption” (after the golf tournament). However, once you pass 14 rental days, all income becomes taxable.

Can I deduct losses from my rental property?

It depends. In most cases, rental income is considered passive, so losses can only offset other passive income. But if you meet certain criteria (like providing substantial services in a short-term rental or qualifying as a real estate professional), you may be able to deduct losses against other income, like W-2 wages.

Do I need to pay estimated taxes on rental income?

Yes, if you expect to owe $1,000 or more in taxes for the year (after withholding). This often applies to rental property owners. You can make quarterly estimated payments or adjust your W-2 withholding if you also have a day job.

How do I report rental income on my taxes?

Use Schedule E (Form 1040) to report income and expenses from rental real estate. You'll list all income earned, deduct allowable expenses, and calculate your net profit or loss for the year.

What happens if I sell a rental property at a loss?

Selling at a loss generally means you won’t owe capital gains tax. In some cases, you may be able to use that loss to offset other capital gains. However, you can’t use a loss on the sale of personal-use property to reduce your taxable income.

What is the 2% rule for rental income?

The 2% rule suggests your monthly rent should be around 2% of the property’s purchase price for the investment to be potentially profitable. For instance, if you purchase a property for $200,000, you’d aim for at least $4,000 in monthly rent. While it’s a useful guideline, it doesn’t account for every market condition, so local demand and operating costs can affect feasibility. Short-term rental hosts also need to consider variable occupancy rates and seasonal trends, which may not align perfectly with simple percentages.

How to pay no taxes on rental income?

Completely eliminating tax on rental income is challenging, but advanced strategies can legally minimize or defer the amount owed. Options include using a 1031 exchange to defer capital gains, leveraging mortgage interest and depreciation deductions, and grouping rental activities to meet real estate professional qualifications.

What is the maximum rental income without tax?

In the United States, there’s no absolute cutoff beneath which rental income is entirely tax-free. Even modest rental earnings must be reported and could generate a tax liability depending on your deductions and total taxable income. To understand your exact obligations, consult a professional and review IRS guidelines.
