Scope. Reflects federal law as of March 5, 2026. The Section 199A deduction expired for tax years beginning after December 31, 2025; this article addresses both 2025 K-1s being filed in 2026 and the post-sunset environment.

1. What Section 199A Is

Section 199A, enacted by TCJA in 2017 and codified at IRC § 199A, provides a deduction of up to 20% of qualified business income (QBI) from pass-through entities including partnerships, S corporations, and sole proprietorships. The deduction is taken at the individual level on Form 1040, separate from itemized deductions, and reduces taxable income.

For LPs in real estate syndications structured as partnerships, the question is whether the K-1 income (and which portions of it) is QBI eligible for the deduction.

2. The 2025 Sunset

Section 199A was enacted with a sunset provision: the deduction expires for tax years beginning after December 31, 2025, unless extended. As of March 2026, no extension has been enacted.

This creates two distinct planning environments:

Multiple proposals have circulated to extend or make permanent the 199A deduction. Some pair extension with rate changes; others would index the income thresholds. None has been enacted. The legislative outlook is discussed below.

3. Pre-Sunset Rules: When Rental Real Estate Qualifies

The threshold question is whether rental real estate constitutes a "trade or business" within the meaning of IRC § 162. The IRS view, articulated in the final 199A regulations and in Publication 535, is that rental activity is QBI-eligible only if it rises to a trade or business level.

Three pathways exist:

4. The Rev. Proc. 2019-38 Safe Harbor

Rev. Proc. 2019-38 provides a safe harbor: a "rental real estate enterprise" is treated as a trade or business if it meets four conditions:

"Rental services" include advertising, lease negotiation, tenant communications, property maintenance, rent collection, and operations management. They exclude financial activities, travel time to the property, and arranging financing.

Most syndication sponsors structure their reporting to qualify each property (or aggregated properties) as a rental real estate enterprise under the safe harbor. The 250-hour threshold is easily met for most active properties when professional property management hours are included.

5. Worked Example

Setup

An LP receives $50,000 of QBI-eligible rental income on a 2025 K-1. The LP files jointly with $400,000 of total taxable income, putting the LP in the 32% federal bracket. The LP's taxable income is below the Section 199A "threshold amount" for joint filers ($394,600 for 2024 indexed for 2025), so wage and UBIA limitations do not apply.

Without 199AWith 199A (20% deduction)Savings
$50,000 taxed at 32%$50,000 less $10,000 deduction
= $16,000 federal tax$40,000 taxed at 32% = $12,800$3,200

The deduction is calculated against taxable income, not gross income, and it cannot create or increase a net operating loss. For LPs at higher income levels (above the threshold), the wage and UBIA tests come into play; see next section.

6. Wage and UBIA-of-Property Limitations

For taxpayers above the threshold amount (around $394,600 joint and $197,300 single for 2025, indexed annually), the deduction is limited to the greater of:

Real estate trades or businesses typically have low W-2 wages (third-party property managers are not employees of the partnership; their fees are not W-2 wages of the partnership) but high UBIA (the building basis itself). The UBIA-based test usually saves the deduction for real estate, where the wage-only test would zero it out.

For a $5,000,000 property purchase, $4,000,000 of building basis (after land allocation) yields $100,000 of capacity under the 2.5% UBIA test, more than enough to support a typical LP allocation.

7. Aggregation Rules

Treas. Reg. § 1.199A-4 permits aggregation of multiple trades or businesses for purposes of the wage and UBIA limitations, provided five tests are met:

Aggregation can be valuable when one rental property has high UBIA but low wages and another has the opposite profile. Combining lets the limits be tested in aggregate.

8. Sunset Implications

Absent legislation, 2026 income reported on 2027 K-1s gets no 199A deduction. For a high-income LP receiving $50,000 of QBI annually, the loss is $3,000 to $5,000 per year in federal tax depending on the bracket.

Across a real estate portfolio of typical size for accredited LPs, the cumulative impact is meaningful but not transformative. The bigger structural question is whether a future Congress restores the deduction, modifies it, or replaces pass-through preferences with a different mechanism (some proposals have suggested rate parity between corporate and pass-through income).

Several legislative scenarios are plausible:

9. How Sponsors Should Structure Reporting

To preserve LP eligibility for 2025 K-1s being filed in 2026:

10. What 2026 LPs Should Ask

Bottom line. For 2025 K-1s being filed in 2026, the Section 199A deduction is real, accessible to most well-structured real estate syndications via the Rev. Proc. 2019-38 safe harbor, and worth several thousand dollars per LP at typical income levels. For 2026 income absent legislation, the deduction is zero. LPs should treat 2025 returns as the last year of certain 199A treatment and plan accordingly.
