Rental Property QBI Deduction: How the 250-Hour Safe Harbor in Rev. Proc. 2019-38 Works.

A W-2 engineer owns two long-term rentals that net $32,000 a year on Schedule E after depreciation. Her S corp friends talk about the 20% pass-through deduction, and she wants to know why her rent should be treated any differently. Rent is different, because §199A only rewards income from a trade or business, and the IRS has never conceded that collecting rent automatically is one. The rental property QBI deduction safe harbor in Rev. Proc. 2019-38 exists to settle that question, and it settles it with a stopwatch: 250 hours a year.

Section 199A hands out a deduction equal to 20% of qualified business income from a qualified trade or business, and Treas. Reg. §1.199A-1(b)(14) defines trade or business by pointing at §162, the same standard that governs business expense deductions. A §162 business requires regular, continuous activity carried on for profit. A landlord who self-manages eight units clears that bar without breaking stride. A landlord who owns one condo, uses a property manager, and thinks about the property twice a year may be holding an investment instead, and investments get no §199A deduction. The case law on where a rental crosses that line is old, thin, and fact-specific, which is exactly why the IRS published a safe harbor.

Rev. Proc. 2019-38 treats a rental real estate enterprise as a §199A trade or business when four things are true. First, you keep separate books and records showing income and expenses for the enterprise, which can be a single property or all of your similar properties together. Second, the enterprise logs 250 or more hours of rental services during the year. Once the enterprise is at least four years old the test softens: 250 hours in any three of the five most recent years. Third, for tax years beginning on or after January 1, 2020, you keep contemporaneous records showing the dates, the hours, a description of the work, and who performed it. Fourth, you attach a statement to the return identifying the properties and confirming the requirements were met.

The 250 hours are not only your hours. Time spent by employees, agents, and independent contractors counts, so a property manager's hours count toward your safe harbor. Rental services include advertising the units, negotiating and signing leases, screening tenant applications, collecting rent, daily operation, maintenance and repairs, buying materials and supplies, managing the property, and supervising the people who do any of this. Excluded: driving to and from the property, arranging financing, hunting for the next acquisition, reviewing financial statements, and hours spent on improvements that must be capitalized under §263A. A gut renovation can consume 400 hours and contribute zero.

Triple net leases are out entirely. If the lease puts the taxes, insurance, and maintenance on the tenant in addition to rent, the revenue procedure will not treat you as running a business no matter how the hours add up. Also out: any property you used as a residence under §280A(d) during the year, which removes a vacation home once your personal use passes the greater of 14 days or 10% of the days it rented at fair value. And property rented to a business you control, though that exclusion costs nothing, because Treas. Reg. §1.199A-1(b)(14) automatically treats a self-rental to your own company as a trade or business, no hour counting required. One structural rule sits underneath all of this: commercial and residential properties may not be combined into a single enterprise, so a landlord with a strip mall and three houses is counting hours in two separate buckets.

At taxable income up to $201,750 single or $403,500 married filing jointly for 2026, per Rev. Proc. 2025-32, the deduction is simply 20% of QBI, capped at 20% of taxable income minus net capital gain, claimed on Form 8995. Above the threshold, a wage-and-asset limit phases in over the next $75,000 single or $150,000 joint, ranges the OBBBA widened from $50,000 and $100,000 beginning in 2026. A directly owned rental rarely pays W-2 wages, so for a high earner the deduction is capped at 2.5% of the unadjusted basis of the qualified property, meaning the building, not the land. A rental with a $500,000 building basis carries a $12,500 ceiling, which is usually more than 20% of its profit anyway. The OBBBA also made §199A permanent, and beginning in 2026 it adds a $400 minimum deduction for anyone with at least $1,000 of QBI from a business they materially participate in.

The safe harbor is one way in, not the only way. A rental that fails the 250-hour test can still claim the deduction if it is a §162 trade or business on its facts, and plenty are; the safe harbor just means the IRS will not argue the point. The reverse cuts too. Trade or business status applies to losses as well as profits. A rental that qualifies and loses money produces negative QBI, which carries forward under §199A(c)(2) and shrinks next year's deduction from your other businesses. Whether you can deduct the loss at all is a separate fight with the passive activity rules, the one the short-term rental crowd wins with material participation. And a profitable year is the wrong time to discover the log does not exist. The contemporaneous records requirement has teeth precisely because a log rebuilt in March for the prior year fails it by definition.
