If the MLP is taxed as a partnership, its Schedule K-1 reports your allocated tax items separately from the cash you receive. Those allocations and distributions affect your tax bill and your adjusted basis, and the eventual sale of your units can require more than comparing the sale price with your original purchase price.
What an MLP distribution is
A master limited partnership (MLP) taxed as a partnership pays distributions under its partnership agreement and applicable policy. As a partner, a unit holder may receive cash and is generally allocated a share of partnership tax items. The cash payment and the allocation are related to the same investment, but they are not the same thing.

This differs from an ordinary corporate dividend: a partnership-taxed MLP generally provides Schedule K-1 information about the investor’s share of income, gains, losses, and deductions. The SEC’s Investor Bulletin on MLPs describes this reporting and related risks. Tax treatment depends on the partnership, the investor’s records and circumstances, and applicable federal, state, and local rules.

How cash, K-1 allocations, and basis interact
The K-1 reports allocated tax items
The partnership reports its tax items and allocates a distributive share to each partner. Schedule K-1 (Form 1065) provides information used to report that share on the partner’s tax return. The K-1 also reports distributions; the IRS’s 2025 Partner’s Instructions for Schedule K-1 describe cash and property distributions in box 19 and explain related basis consequences.
#1 Best Overall
Cash distributions generally reduce adjusted basis
Adjusted basis—often called outside basis—is a tax measure of a partner’s investment in the partnership. It is not necessarily the purchase price shown in a brokerage account. Under the general rules in IRS Publication 541, money and the adjusted basis of distributed property reduce a partner’s basis, but not below zero. Allocated income and other partnership items also affect basis, so accurate tracking requires the K-1 information and relevant records over time.
A distribution can trigger gain if it exceeds basis
A partner generally recognizes gain when money distributed exceeds adjusted basis immediately before the distribution. Special rules apply, including rules treating certain marketable securities as money, and exceptions may matter. The IRS instructions and Publication 541 set out the general framework; do not assume every distribution is tax-free merely because it is described as a return of capital or because no corporate-style dividend was reported.
Can you owe tax without receiving cash?
Yes. A K-1 may allocate taxable income or other items even in a period when the MLP makes no cash distribution. The SEC notes that partnership items can result in federal, state, or local tax obligations without matching cash. It gives discharged partnership debt as one possible source of taxable income; the consequences depend on the facts and applicable tax rules, not every debt restructuring having an identical result.
The reverse distinction matters too: receiving cash does not tell you by itself how much taxable income was allocated to you. Read the K-1 and account for basis adjustments rather than treating the distribution amount as your taxable income.
What happens when you sell MLP units?
Your sale result can be more complicated than proceeds minus original purchase cost. Your adjusted basis may have changed through allocated partnership items and past distributions. The applicable tax calculation therefore depends on the adjusted basis and the partnership tax information, along with the rules governing the sale. Keep K-1s and basis records for the full holding period, and ask a tax professional familiar with partnership interests to review the sale when needed.

Distributions are not guaranteed
A stated, regular, or anticipated distribution is not a promise. An MLP can reduce or suspend payments; its partnership agreement, current disclosures, and financial condition matter for its specific policy. Unit prices can also fall, and investors can lose some or all of their investment.

State tax filings may be relevant
Because an MLP may operate in multiple states, its activity can create state tax reporting or filing considerations for some investors. That does not establish that every holder must file in every state where the partnership operates. Check the K-1 and relevant state rules against your own circumstances.
Review governance and business risks in issuer filings
MLPs can have partnership-specific governance arrangements, sponsor relationships, and conflicts of interest. Business, commodity, leverage, and market risks also vary. Review the issuer’s current filings and partnership agreement rather than assuming all MLPs have the same structure or risk profile.
Quick Recap
What to check before and after investing
- Before buying: Read the partnership’s current filings and agreement for distribution policy, risks, governance, and any sponsor relationships that may affect unit holders.
- When tax documents arrive: Review the Schedule K-1 allocations and distribution reporting; do not use the cash payment as a substitute for the tax information.
- For basis records: Retain purchase records, annual K-1s, and distribution information so adjusted basis can be tracked rather than inferred from brokerage cost alone.
- For filing questions: Consider federal and possible state obligations, and get tax advice tailored to your facts, especially if you sell units or have a complex K-1.
