The tax treatment of a return of capital distribution is neither automatically good nor automatically bad: the IRS does not tax it as income in the year you receive it, but it lowers your cost basis by the same amount, so you owe more capital gains tax when you eventually sell. Whether that trade favors you depends on why the money is coming back. A REIT distributing cash backed by real property income while depreciation shelters the reported earnings is a very different situation from a closed-end fund cannibalizing its own assets to hit a yield target.
How the Basis Reduction Works
Your cost basis is what you originally paid for the investment. Each return of capital distribution reduces that basis dollar for dollar.1Internal Revenue Service. Topic No. 404, Dividends and Other Corporate Distributions Nothing is taxed now because the IRS treats the payment as a return of your own money, not new earnings.
The lower basis catches up with you at sale. Buy shares at $50, collect $10 in return of capital over several years, and your adjusted basis is $40. Sell later at $55, and the taxable gain is $15 rather than $5. The tax is deferred, not erased. For an investor holding a position for years or decades, that deferral has real value: the money that would have gone to taxes stays invested and keeps compounding.
When Your Basis Reaches Zero
Basis can’t go below zero. Once it’s exhausted, any further nondividend distributions are taxed immediately as gain from the sale or exchange of property.2Office of the Law Revision Counsel. 26 USC 301 Distributions of Property The deferral is over even though you haven’t sold anything.
Whether that gain gets long-term or short-term treatment depends on how long you’ve held the shares. More than a year qualifies for long-term capital gains rates; a year or less means ordinary income rates.3Office of the Law Revision Counsel. 26 USC 1222 Other Terms Relating to Capital Gains and Losses Most investors receiving return of capital have owned the position long enough for the lower long-term rate to apply.
When Return of Capital Works in Your Favor
Real estate investment trusts and master limited partnerships produce most of the return of capital that individual investors see, and here the classification is usually a sign of financial strength. These entities own buildings, pipelines, and other depreciable assets that generate cash but also carry large depreciation deductions on paper. Depreciation is a non-cash accounting expense: it lowers reported taxable income while the actual cash coming in stays high. When distributed cash exceeds reported taxable earnings, the excess is labeled return of capital.
You get the good end of that deal. The underlying properties are producing income, the business is operationally sound, and the return of capital label is a byproduct of depreciation accounting. Cash arrives now, tax is deferred until sale, and your money compounds in the meantime.
The Section 199A Deduction
REIT investors get a separate advantage on the ordinary dividend portion of their distributions. Section 199A lets you deduct up to 20% of qualified REIT dividends from taxable income, and the One Big Beautiful Bill Act made that deduction permanent in July 2025, so it applies for 2026 and beyond. Return of capital does not qualify. The deduction attaches to the Section 199A dividends reported in Box 5 of your 1099-DIV, not the nondividend distributions in Box 3. If a large share of your REIT payout is classified as return of capital, the 199A slice is smaller than the headline distribution suggests.
When Return of Capital Is Destructive
Some closed-end funds and managed distribution plans use return of capital for a much less healthy reason: to sustain a target payout they can’t actually earn. The fund sets a distribution rate and holds it whether markets cooperate or not. When interest income and realized gains fall short, the shortfall comes straight out of net asset value. The fund is handing you your own money back and calling it yield.
Each such distribution shrinks the asset base that generates future returns. The share price drifts lower even as the headline yield stays constant. An investor watching only the payout rate can miss that the fund is quietly liquidating itself.
The warning sign is a persistent decline in net asset value per share while the distribution rate holds steady. Compare total return (price change plus distributions) with the distribution rate. If total return trails the payout year after year, principal is being eroded. A fund distributing 8% annually on a 4% total return is losing 4% of its asset base each year, and that math catches up fast.
MLPs, K-1s, and the IRA Trap
Master limited partnerships report differently. Instead of a 1099-DIV, you get a Schedule K-1 (Form 1065) showing your share of the partnership’s income, deductions, and distributions.4Internal Revenue Service. Partners Instructions for Schedule K-1 Form 1065 (2025) Cash distributions show up in Box 19, Code A. K-1s arrive later than 1099s, often in March, and add complexity to the return.
Holding MLPs inside an IRA creates a problem most investors don’t anticipate. Because MLPs operate as partnerships in active trades, their income can count as unrelated business taxable income, and tax-advantaged accounts are not fully shielded from it. When gross UBTI in a single IRA exceeds $1,000 in a year, the IRA itself owes tax on the excess at trust rates running from 10% to 37%.5Office of the Law Revision Counsel. 26 USC 512 Unrelated Business Taxable Income The tax comes out of the IRA’s own assets, and a return has to be filed. The deferral benefit of the IRA and the deferral benefit of MLP return of capital work against each other rather than stacking. Exchange-traded funds that hold MLPs in a corporate wrapper can sidestep the UBTI issue if you want the exposure inside a retirement account.
Why Long Holders Benefit Most: The Step-Up at Death
Death resets the basis math. Property inherited from a decedent gets a new basis equal to fair market value on the date of death.6Office of the Law Revision Counsel. 26 USC 1014 Basis of Property Acquired From a Decedent All those years of basis reductions from return of capital distributions are wiped clean. The deferred gain that was building up over the original owner’s lifetime disappears.
That combination — cash flow with deferred tax during life, basis reset at death — is one of the strongest arguments for holding depreciating income assets like REITs for the long term. The lifetime taxes never come due, and the heirs start over at current market value.
Reporting and Calculating the Gain When You Sell
Return of capital shows up in Box 3 of Form 1099-DIV as “Nondividend Distributions.”7Internal Revenue Service. Form 1099-DIV Dividends and Distributions Don’t add it to the ordinary dividends in Box 1a; instead, subtract the Box 3 amount from your basis in your own records for that year. MLP investors work from Box 19 of the K-1.
Keep a running tally of adjusted basis for every position that pays return of capital. Your brokerage may track basis for covered shares, but the ultimate responsibility falls on you.8Internal Revenue Service. Publication 550 (2025), Investment Income and Expenses
When you sell, gain equals sale price minus adjusted basis, not original cost. Buy 100 shares at $30 for $3,000, collect $800 in return of capital over five years, and your basis is $2,200. Sell all 100 at $35 for $3,500 and the taxable gain is $1,300, not $500. Report it on Schedule D and Form 8949.1Internal Revenue Service. Topic No. 404, Dividends and Other Corporate Distributions If basis was already at zero when you sold, the whole sale price is gain, and any nondividend distributions received after basis reached zero were already taxable in the years they arrived.8Internal Revenue Service. Publication 550 (2025), Investment Income and Expenses Losing track of basis is the most common way investors underreport gains and draw an IRS notice. A spreadsheet updated once a year when the 1099-DIV or K-1 arrives is enough to stay ahead of it.
