QBI deduction (199A)

The qualified business income deduction under Section 199A is one of the most valuable everyday tax breaks for real estate investors, and as of 2025 it is permanent. It lets owners of passthrough businesses, including qualifying rental real estate, deduct up to 20% of their net business income before it hits the tax brackets. On $100,000 of qualifying rental profit, that is a $20,000 deduction for doing nothing extra except qualifying. The 2025 tax law removed the deduction’s scheduled expiration, so it is now a permanent fixture worth building a portfolio around, provided your rentals clear the one real hurdle: being a trade or business.

What the deduction does, and its permanence

Section 199A gives non-corporate taxpayers, sole proprietors, single-member LLCs, partnerships, S corporations, a deduction of up to 20% of their qualified business income. For a real estate investor, that means up to 20% of your net rental income can be deducted before tax, on top of all your ordinary deductions and depreciation. It is a below-the-line deduction you get whether or not you itemize.

The big 2025 development is permanence. The deduction had been scheduled to expire after December 31, 2025; the One Big Beautiful Bill Act made it permanent starting in 2026, removing the sunset that had clouded long-term planning. The law also expanded the phase-in ranges to $75,000 single and $150,000 joint and added a $400 minimum deduction for active business owners with at least $1,000 of qualified business income. The 2026 taxable-income thresholds where the wage-and-property limitations kick in are $197,300 single and $394,600 joint, indexed annually. For real estate, those limitations tend to be favorable, because the rules count the basis of your property, and a leveraged real estate portfolio carries a lot of it.

Section 199A deducts up to 20% of qualifying rental income before tax, and the 2025 law made it permanent with expanded phase-in ranges and a new $400 minimum for active business owners.

The trade-or-business hurdle, and the safe harbor

Here is the catch that trips up landlords: rental income does not automatically qualify. To get the 199A deduction, your rental activity must rise to the level of a trade or business under the tax law, and a passive, hands-off rental might not. Without a clear rule, this was a case-by-case facts-and-circumstances question that left owners guessing.

The IRS solved the uncertainty with a safe harbor in Revenue Procedure 2019-38. Meet its conditions and your rental real estate enterprise is treated as a trade or business for 199A, no facts-and-circumstances argument required. The conditions: maintain separate books and records for each rental enterprise; perform at least 250 hours of rental services per year for the enterprise, where the hours can be done by you, your employees, agents, or independent contractors (so a property manager’s hours count); and keep contemporaneous records, time logs, describing the services, who performed them, and when. Rental services include advertising, tenant screening, lease negotiation, rent collection, maintenance, repairs, and management. The safe harbor applies at the enterprise level, and you can treat multiple properties as a single enterprise to reach the 250 hours collectively.

Rental income qualifies for 199A only if it is a trade or business, and the Rev. Proc. 2019-38 safe harbor gets you there with 250 hours of rental services, separate books, and contemporaneous records.

The planning angle for a portfolio

The 250-hour safe harbor is where the strategy meets the paperwork, and the key insight is that the hours can be aggregated and can be performed by contractors. An investor with several properties can group them into one rental enterprise and count all the hours across the portfolio, including hours worked by a property manager or maintenance contractor, toward the single 250-hour threshold, which most active portfolios clear comfortably. That makes the safe harbor achievable for investors who use professional management, not just hands-on landlords.

The two practical requirements are therefore organizational, not physical: keep genuinely separate books for the enterprise, and keep a real contemporaneous log of the 250-plus hours and who performed them. Investors who lose the 199A safe harbor almost always lose it on records, not hours, they did the work but cannot prove it. Set up the bookkeeping and the time log at the start of the year, and a permanent 20% deduction on your rental income follows. Because 199A is now permanent, that setup pays off every year going forward, which is exactly why it is worth doing properly once.

Because the safe harbor’s 250 hours can be aggregated across a portfolio and performed by contractors, most active investors qualify, and the deduction is usually lost on recordkeeping rather than hours.

The bottom line

• Section 199A deducts up to 20% of qualifying rental income before tax, and the 2025 law made it permanent.
• Rental income qualifies only if the activity rises to the level of a trade or business.
• The Rev. Proc. 2019-38 safe harbor treats a rental enterprise as a trade or business if its conditions are met.
• Those conditions are 250 hours of rental services, separate books, and contemporaneous records.
• The 250 hours can be aggregated across a portfolio and done by contractors, so most active investors qualify.
