How MLP K-1 Taxation Works
Master Limited Partnerships pass their income, deductions, and credits directly to unit-holders via Schedule K-1. Unlike dividends, most MLP distributions are treated as return of capital β they reduce your tax basis rather than creating immediate taxable income.
Basis After Year = Beginning Basis + K-1 Ordinary Income β Distributions β Depreciation/IDC
Taxable Distributions = max(0, Distributions β Beginning Basis)
199A QBI Deduction = K-1 Box 1 Ordinary Income Γ 20%
On Sale: Ordinary Recapture = cumulative basis reductions from depreciation/IDC
Capital Gain on Sale = Sale Price β Adjusted Basis β Ordinary Recapture
Taxable Distributions = max(0, Distributions β Beginning Basis)
199A QBI Deduction = K-1 Box 1 Ordinary Income Γ 20%
On Sale: Ordinary Recapture = cumulative basis reductions from depreciation/IDC
Capital Gain on Sale = Sale Price β Adjusted Basis β Ordinary Recapture
Example: $20,000 basis, $4,000 distributions, $2,500 K-1 income, $1,200 depreciation/IDC
Basis reduction: $4,000 + $1,200 = $5,200 (partially offset by $2,500 income)
Ending basis: $20,000 β $4,000 β $1,200 + $2,500 = $17,300
Taxable distributions this year: $0 (basis still positive)
199A deduction: $2,500 Γ 20% = $500
Basis reduction: $4,000 + $1,200 = $5,200 (partially offset by $2,500 income)
Ending basis: $20,000 β $4,000 β $1,200 + $2,500 = $17,300
Taxable distributions this year: $0 (basis still positive)
199A deduction: $2,500 Γ 20% = $500
Multi-State Filing Note
Large MLPs operate across 30+ states. You may receive K-1 footnotes requiring state tax returns in multiple states. Filing thresholds vary β many states require returns only when your allocable income exceeds a de minimis amount ($1,000β$5,000). Failure to file can result in composite return inclusion by the partnership or state-level penalties.

Multi-State K-1 Filing Note
Large MLPs (ET, EPD, MMP, PAA, etc.) allocate income to 30+ states. You receive state K-1 footnotes showing income by state. Many states have de minimis thresholds. Review Schedule K-1 footnotes and consult a tax advisor for state filing obligations. The MLP may offer a composite return option to simplify multi-state filing.

Frequently Asked Questions
Why are MLP distributions mostly tax-deferred, not immediately taxable?
MLP distributions are treated as a return of capital as long as you have remaining tax basis in your units. This means each distribution reduces your basis rather than creating immediate taxable income. Once your basis reaches zero, all further distributions become taxable as ordinary income. This deferred-tax nature is one of the key tax advantages of MLPs β you defer taxes on most distributions until you sell.
What is the 199A deduction for MLP investors?
Under IRC Β§199A, MLP investors may deduct up to 20% of qualified business income (QBI) reported on Box 1 of the K-1. This deduction reduces taxable income but not self-employment tax. For 2026, the QBI deduction limit is 20% of QBI or 20% of taxable income minus net capital gain, whichever is lower. MLPs are generally not specified service trades, so the full 20% typically applies regardless of income level.
What happens to depreciation and IDC adjustments on an MLP K-1?
MLPs pass through depreciation (from pipeline and equipment) and Intangible Drilling Costs (IDC) as deductions that reduce your basis each year. These reductions mean your basis declines faster than just through cash distributions. When you sell, the cumulative ordinary income items (from basis adjustments) may be subject to recapture as ordinary income under IRC Β§751 (hot assets) rather than capital gains rates.
What is UBTI and why does it matter for IRAs holding MLPs?
Unrelated Business Taxable Income (UBTI) is income from active business operations, including MLP income. IRAs are tax-exempt, but UBTI over $1,000 triggers Unrelated Business Income Tax (UBIT) on the IRA itself at trust tax rates (up to 37% in 2026 on income over $15,200). The IRA pays this tax, reducing the tax advantages of holding MLPs in an IRA. Most tax advisors recommend holding MLPs in taxable accounts, not IRAs.
How is gain taxed when I sell MLP units?
When you sell MLP units, the gain is split into two components: (1) Ordinary income recapture β the portion equal to all previously deducted depreciation and IDC allocated to you (reported on IRS Form 4797 and taxed at ordinary income rates up to 37%); and (2) Capital gain β any remaining gain above the ordinary recapture amount, taxed at capital gains rates. The ordinary recapture portion is often larger than investors expect, especially after holding for many years.
