The QBI Deduction Is Now Permanent: What Short-Term Rental Owners Need to Know

The qualified business income (QBI) deduction under Section 199A allows eligible taxpayers to deduct 20% of their qualified business income from pass-through businesses. For short-term rental investors, the potential benefit is significant — but whether your STR activity qualifies depends on how it's classified. OBBBA, signed July 4, 2025, made this deduction permanent (it was set to expire at the end of 2025), which changes the long-term planning calculus considerably.

What the QBI Deduction Does

Section 199A allows individuals, estates, and trusts to deduct up to 20% of their qualified business income from a qualified trade or business. If your STR activity generates $60,000 in net income and qualifies as a trade or business, the QBI deduction reduces your taxable income by $12,000 — at a 37% marginal rate, that's $4,440 in federal tax savings on top of the depreciation deductions you're already taking.

Does Your STR Qualify as a Trade or Business?

This is the core question for STR owners. The IRS requires that a QBI-eligible activity constitute a "trade or business" under IRC §162 — meaning it must be conducted with regularity and continuity, with a profit motive, and involve more than just investing. Passive rental activities are specifically excluded from the QBI deduction under Reg. §1.199A-1(b)(14).

For STR investors using the STR loophole, the activity is already classified as non-rental (due to the 7-day average stay rule) and treated as active (due to material participation). This non-rental, active classification strongly supports trade or business treatment for QBI purposes. Investors who materially participate and run their STR with the regularity and continuity of a business have a solid basis for claiming the deduction.

The Safe Harbor for Rental Activities

Rev. Proc. 2019-38 provides a safe harbor under which rental real estate activities can qualify for the QBI deduction. To use the safe harbor, you must: (1) maintain separate books and records for the rental activity, (2) perform 250 or more hours of rental services per year (or average 250 hours over 3 of 5 years), and (3) attach a statement to your return affirming compliance.

For STR investors who are already tracking 100–500+ hours for material participation purposes, the 250-hour threshold of the safe harbor is often achievable. However, the safe harbor has an explicit exclusion: rental activities with an average rental period of 7 days or fewer are excluded from the rental safe harbor. STRs that qualify for the loophole (average stay ≤7 days) must rely on direct trade or business treatment — not the safe harbor.

Income Thresholds and W-2 Wage Limitations

The QBI deduction has income thresholds above which W-2 wage limitations apply. For 2026, taxpayers with taxable income above approximately $197,300 (single) or $394,600 (joint) are subject to the W-2 wage limitation — the deduction cannot exceed 50% of W-2 wages paid by the business or 25% of wages plus 2.5% of the unadjusted basis of qualified property.

For most STR investors, the W-2 wage limitation is a concern because rental operations rarely pay W-2 wages. The unadjusted basis limitation (25% + 2.5% of property basis) can help — on a $500,000 property, 2.5% of basis is $12,500 in additional deductible QBI. High-income investors above the threshold should model the W-2 wage limitation with their CPA.

Why the Permanence Matters for Long-Term Planning

Before OBBBA, the QBI deduction was set to expire after December 31, 2025. The sunset created uncertainty for investors considering whether to structure their STR operations to qualify. OBBBA removes that uncertainty — investors can now plan with confidence that the 20% deduction will be available in all future years without needing to anticipate legislative renewal.

For STR investors building multi-property portfolios, the QBI deduction creates a recurring 20% reduction in the tax on net income from the activity. As depreciation benefits taper off in years 3–10 of property ownership, the QBI deduction becomes an increasingly important ongoing tax benefit.
