§199A QBI Deduction Calculator — Rental Property 2026

Section 199A lets qualifying rental investors deduct up to 20% of net rental income from federal taxable income — potentially $14,800/year in savings at the 37% bracket on $200,000 of rental income. But the deduction phases out above $201,750 (single) / $403,500 (MFJ), and above that range it is limited to the greater of 50% of W-2 wages paid or 25% of wages plus 2.5% of the depreciable property basis. This calculator handles all three tiers.

Your Tax Profile

Filing status

Taxable income before QBI deduction ($)
Ordinary income only — W-2 wages, business income, rental income, interest. Exclude capital gains and qualified dividends, which are not used in the §199A taxable-income cap.

Your Rental QBI

Net QBI from rental activities ($)
Rental income minus all Schedule E expenses: mortgage interest, property taxes, insurance, repairs, management fees, depreciation (including bonus depreciation). Aggregate multiple properties if using the aggregation election.

Does your rental qualify as a §162 trade or business?

I materially participate in the rental activity
Required for the 2026 OBBBA $400 minimum deduction when QBI ≥ $1,000. Not required for the standard 20% deduction calculation.

W-2 Wage & Property Basis (Above-Threshold Investors)

These inputs only affect the deduction if your taxable income exceeds the phase-out threshold. Enter $0 if uncertain — the calculator will flag whether these limits apply.

W-2 wages paid by your rental business in 2026 ($)
Wages on W-2s issued by your rental LLC or property management entity. Most individual landlords with no employees: $0.

Unadjusted basis of qualified property — UBIA ($)
Original depreciable cost basis of qualifying rental properties placed in service within the last 10 years. Building/improvements only — exclude land. Do NOT reduce for depreciation claimed. Example: bought for $480K, land $80K → UBIA = $400K.

How the §199A calculation works for rental investors

Tier 1 — Below the phase-out threshold

If your taxable income (ordinary income, before the QBI deduction) is at or below $201,750 (single) / $403,500 (MFJ), the calculation is simple:

Your deduction = 20% of net QBI, capped at 20% of ordinary taxable income.
No W-2 wage limitation. No UBIA formula. No phase-out math.
A rental investor netting $100,000 in this tier gets a $20,000 deduction — worth $7,400 at the 37% bracket.

Tier 2 — In the phase-out range

Between $201,750–$276,750 (single) or $403,500–$553,500 (MFJ), the W-2/UBIA limitation is phased in gradually. If the W-2/UBIA limit would have reduced your deduction from $20,000 to $8,000, and you're exactly 40% through the phase-out range, your deduction is $20,000 − (40% × $12,000) = $15,200. The phase-in range was widened from $50K to $75K (single) and from $100K to $150K (MFJ) under the OBBBA — giving investors more runway before the full limitation bites.¹

Tier 3 — Above the phase-out threshold

Above $276,750 (single) / $553,500 (MFJ), the deduction is fully W-2/UBIA limited:

Formula 1: 50% of W-2 wages paid by the rental activity
Formula 2: 25% of W-2 wages + 2.5% of unadjusted basis immediately after acquisition (UBIA) of qualified property
Your limit = the greater of the two formulas, capped at 20% × QBI

Most individual landlords pay no W-2 wages, so Formula 2 (2.5% × UBIA) is the primary lever. A portfolio with $2,000,000 of UBIA supports up to $50,000 of QBI deduction regardless of wages.

The UBIA formula: why it matters for rental investors

UBIA (Unadjusted Basis Immediately after Acquisition) is the original cost basis of qualifying property at the time it was placed in service — not reduced for depreciation claimed, not stepped up, and excluding land. For a $600,000 rental where land is $120,000 and building is $480,000, UBIA = $480,000.

2.5% × $480,000 = $12,000 maximum W-2 limitation under Formula 2 with no employees
20% × $96,000 QBI = $19,200 basic deduction
Final deduction = min($19,200, $12,000) = $12,000 — the UBIA formula is the binding constraint

UBIA only counts for the first 10 years a property is placed in service. Properties acquired more than 10 years ago contribute $0 to the UBIA formula. Adding new properties — or doing a cost segregation study that increases the depreciable basis of existing property by reclassifying components — can grow the UBIA ceiling.

Does your rental qualify?

Section 199A requires the rental activity to constitute a "trade or business" under IRC §162. For rental real estate, there are two paths to qualification:

250-hour safe harbor (Rev. Proc. 2019-38). If the rental enterprise (all qualifying properties aggregated) has at least 250 hours per year of rental services — including time spent by owners, employees, and agents — and you maintain contemporaneous time records, the activity is treated as a §162 trade or business. Triple-net leases are explicitly excluded from this safe harbor.
Facts and circumstances. Even without 250 hours, a rental can qualify if the activity rises to the level of a regular, continuous, and substantial business under the general §162 standard. Courts and IRS guidance suggest most actively managed residential rentals qualify, though NNN leases that are truly passive typically don't.

Self-rental arrangements (leasing a property to your own S-corp or C-corp) require special analysis — the QBI treatment depends on how the activity is characterized and whether the entities are commonly owned.

New in 2026: OBBBA changes

Permanent deduction. The OBBBA (signed July 2025) eliminated the December 31, 2025 sunset. §199A has no expiration date under current law.¹
Widened phase-in range. The range over which the W-2/UBIA limitation phases in was expanded — from $50,000 to $75,000 (single) and from $100,000 to $150,000 (MFJ). Higher-income investors retain more of the deduction before it's fully limited.¹
$400 minimum deduction. A taxpayer with QBI of at least $1,000 who materially participates in a qualified trade or business may claim a minimum §199A deduction of $400, even if the standard calculation yields less (including zero due to the W-2 limitation).¹
2026 inflation-adjusted thresholds. The lower threshold rises from $394,600 to $403,500 (MFJ) and from $197,300 to $201,750 (single) per IRS Rev. Proc. 2025-61.²

Get the deduction modeled against your actual numbers

The §199A calculation interacts with your overall income picture, entity structure, REPS status, cost segregation basis, and aggregation elections in ways the calculator can't fully capture. Whether you're below the threshold and collecting the full 20%, in the phase-out trying to optimize the W-2/UBIA ceiling, or wondering if reducing taxable income via a Solo 401(k) or cash balance plan makes the threshold math work in your favor — a specialist can model the actual dollar value.
