A rental property counts as a trade or business under Section 162 when you manage it with continuity and regularity and your primary purpose is earning income or profit. That standard comes from the Supreme Court’s decision in Commissioner v. Groetzinger, and it separates landlords running an active operation from those passively collecting rent on a hands-off investment.1Cornell Law School. Commissioner of Internal Revenue v. Robert P. Groetzinger Getting on the right side of that line changes which expenses you can deduct, whether you owe the 3.8% net investment income tax on rental profits, and whether you qualify for the 20% qualified business income deduction.
The Section 162 Test
Section 162 lets you deduct “all the ordinary and necessary expenses paid or incurred during the taxable year in carrying on any trade or business.”2Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses The statute never defines the term, so the courts filled the gap. Under Groetzinger, two things have to be true: the activity is conducted with continuity and regularity, and your primary purpose is income or profit.1Cornell Law School. Commissioner of Internal Revenue v. Robert P. Groetzinger
No single factor decides it. The IRS and Tax Court weigh several:
- Number of properties. Owning and managing multiple units makes the continuity-and-regularity argument much easier than a single-family home.
- Time spent. Regular, ongoing management activities such as maintenance, tenant screening, rent collection, and bookkeeping point toward a business.
- Services provided to tenants. Substantial services beyond handing over a key strengthen the case. A triple-net lease where the tenant handles taxes, insurance, and maintenance looks like an investment.
- Owner involvement. Sporadic or minimal involvement cuts against trade or business status. Courts want to see hands-on management, not an occasional phone call to a property manager.
A single-property landlord can qualify, but the burden of proof is heavier. You need clear evidence of regular management effort to convince the IRS that you’re running a business rather than holding an investment.
What Changes When Your Rental Qualifies
If your rental doesn’t rise to trade or business status, the fallback is Section 212, which permits deductions for expenses related to producing income or managing investment property.3Office of the Law Revision Counsel. 26 USC 212 – Expenses for Production of Income On paper that sounds fine. In practice it’s nearly useless right now.
Section 212 expenses are miscellaneous itemized deductions subject to the 2% AGI floor. The Tax Cuts and Jobs Act suspended those deductions for individuals, and the One Big Beautiful Bill Act made the suspension permanent starting in 2026. If your rental is treated as an investment activity, you lose the ability to deduct management fees, legal costs, and similar operating expenses altogether. Depreciation and mortgage interest survive regardless of classification, but the gap between Section 162 and Section 212 treatment is wider today than it has ever been.
Once your rental clears the Section 162 threshold, ordinary operating costs come back into play: property management fees, insurance premiums, utilities you pay as landlord, advertising, and mortgage interest on loans used to acquire or improve the property.2Office of the Law Revision Counsel. 26 USC 162 – Trade or Business Expenses Repairs that maintain the property without adding value or extending its life are deductible immediately; capital improvements have to be capitalized and depreciated. State and local property taxes are deductible as a business expense on Schedule E, which means they’re not subject to the $40,400 SALT deduction cap that applies to personal itemized deductions in 2026.4Internal Revenue Service. Topic No. 503, Deductible Taxes A home office deduction becomes available if the space is used exclusively and regularly as the principal place of business for managing your rentals.
The Section 199A Safe Harbor for Rentals
The Section 199A deduction knocks 20% off qualified business income, but you only get it if your rental is a trade or business. Rather than force landlords through the Groetzinger analysis, the IRS gave them a checklist in Revenue Procedure 2019-38.5Internal Revenue Service. IRS Finalizes Safe Harbor to Allow Rental Real Estate to Qualify as a Business for Qualified Business Income Deduction Meet its terms and your rental is treated as a trade or business for QBI purposes, full stop. The safe harbor doesn’t override the passive activity rules; it only settles the trade-or-business question for the deduction.6IRS. Rev. Proc. 2019-38
Three requirements have to be satisfied every year:
- Separate books and records for each rental enterprise.
- At least 250 hours of rental services. Enterprises less than four years old need 250 hours in the current year. Enterprises four years or older need 250 hours in at least three of the last five tax years.6IRS. Rev. Proc. 2019-38
- Contemporaneous logs showing dates, services performed, and hours spent.
Qualifying rental services include maintenance, repairs, rent collection, paying expenses, providing tenant services, and marketing the property. Travel to the property, arranging financing, and reviewing financial statements do not count. You also have to attach a signed statement to your return for every year you elect the safe harbor. Miss that step and the election is invalid for the year.
Two categories of property are excluded. Any property you use as a personal residence during the year, and any property leased under a triple-net lease. Both exclusions reinforce the same theme: passive, hands-off ownership doesn’t get business treatment.
The QBI deduction itself has income-based limits worth knowing. For 2026, the deduction is fully available below $201,750 of taxable income for single filers and $403,500 for joint filers. Above those thresholds, limitations tied to W-2 wages paid and the cost basis of qualified property phase in, completing at $276,750 and $553,500. Rental activities rarely pay W-2 wages, so for higher-income landlords the property’s unadjusted basis becomes the relevant limiting factor.
Trade or Business Status Doesn’t Fix the Passive Loss Problem
This is the point most landlords miss. Even when a rental clearly qualifies as a Section 162 trade or business, Section 469 treats all rental activities as passive, no matter how many hours the owner puts in.7Office of the Law Revision Counsel. 26 USC 469 – Passive Activity Losses The regular material participation test that applies to other businesses is expressly turned off for rentals. It’s a blanket rule that catches full-time landlords by surprise.
The consequence: passive losses only offset passive income. If your rental runs at a loss, you can’t use it against your salary, business profits, or portfolio income. Unused losses get suspended and carried forward until you have enough passive income to absorb them or you sell the property in a fully taxable transaction.8Internal Revenue Service. Topic No. 425, Passive Activities – Losses and Credits Qualifying as a trade or business under Section 162 doesn’t change that. The two questions — is this a trade or business, and is it passive — are answered separately.
Real Estate Professional Status
The way out of the passive rental default is the Real Estate Professional designation. Qualify, and the per se passive rule for rentals is switched off; your rentals are then tested under the ordinary material participation standards like any other business.7Office of the Law Revision Counsel. 26 USC 469 – Passive Activity Losses Two annual time-based tests apply:
- More than 50% of the personal services you perform across all trades or businesses during the year must be in real property trades or businesses where you materially participate. Real property trades or businesses include development, construction, rental operations, management, leasing, and brokerage.9Internal Revenue Service. Publication 925 (2025), Passive Activity and At-Risk Rules
- You perform more than 750 hours of services during the year in those real property trades or businesses.9Internal Revenue Service. Publication 925 (2025), Passive Activity and At-Risk Rules
For married couples, either spouse can meet the 750-hour test individually, and their hours count together. Only one spouse has to independently satisfy the more-than-half test, which is why a full-time W-2 employee married to a full-time landlord can still benefit.
Clearing REP status isn’t the finish line. You still have to materially participate in each rental separately, and the cleanest way is logging more than 500 hours in the activity.9Internal Revenue Service. Publication 925 (2025), Passive Activity and At-Risk Rules For landlords with several properties, hitting 500 hours on each one is impractical, so most elect to treat all their rental interests as a single activity. That grouping lets you meet the 500-hour test once for the whole portfolio.
Documentation is where REP claims usually fall apart. Publication 925 says you can establish participation by “any reasonable method,” listing appointment books, calendars, and narrative summaries.9Internal Revenue Service. Publication 925 (2025), Passive Activity and At-Risk Rules In practice, taxpayers who reconstruct hours from memory after receiving an audit notice almost always lose. A spreadsheet or calendar noting date, activity, and hours, kept up weekly, is the most reliable protection.
The 3.8% Net Investment Income Tax
The net investment income tax applies at 3.8% to the lesser of your net investment income or the amount by which your modified AGI exceeds $200,000 for single filers and $250,000 for joint filers. Those thresholds are not indexed for inflation.10Internal Revenue Service. Questions and Answers on the Net Investment Income Tax
Rental income is generally caught by the tax. The important exception: if your rental is a trade or business and you materially participate, the income is treated as operating income from a nonpassive business and is excluded.11eCFR. 26 CFR 1.1411-5 – Trades or Businesses to Which Tax Applies The same exclusion covers gain on selling the property.
That creates a real incentive to qualify on both fronts, as a Section 162 trade or business and as a Real Estate Professional with material participation. A landlord who clears both avoids the 3.8% tax on rental profits and on gain at sale. A landlord who doesn’t pays it on every dollar above the AGI threshold. On $100,000 of net rental profit, that’s up to $3,800.
Self-Employment Tax Doesn’t Follow
Trade or business status doesn’t drag rental income into self-employment tax. Section 1402 specifically carves rents from real estate out of net earnings from self-employment.12Office of the Law Revision Counsel. 26 USC 1402 – Definitions The exclusion holds even when your rental qualifies as a trade or business under Section 162, which is one of the few places where a fuzzier line actually helps.
The narrow exception is the “real estate dealer” — someone who buys and sells properties as inventory rather than holding them for rental income. Landlords who buy, renovate, and flip alongside a rental portfolio need to keep those activities clearly separated on the books. A standard buy-and-hold investor doesn’t face this issue.
