A non-dividend distribution is a payment from a corporation, REIT, or mutual fund that isn’t backed by the company’s earnings and profits, so it isn’t taxed as dividend income when you receive it. Instead, it’s treated as a return of your own investment: you reduce the cost basis of your shares by the amount received, and you only owe tax if those payments eventually drive your basis below zero. You’ll see the amount reported in Box 3 of Form 1099-DIV.
How the Tax Treatment Works
Federal law runs every dollar a corporation distributes through three tiers in a strict order. You can’t skip ahead, and the label on the check doesn’t matter — the corporation’s earnings and profits (E&P) decide which tier each dollar lands in.1Office of the Law Revision Counsel. 26 USC 301 – Distributions of Property
The first tier is a taxable dividend. To the extent the corporation has current or accumulated E&P to back the payment, that portion is a dividend and gets reported as dividend income.2Office of the Law Revision Counsel. 26 USC 316 – Dividend Defined If you held the stock at least 61 days during the 121-day window around the ex-dividend date, the dividend qualifies for the lower long-term capital gains rates of 0%, 15%, or 20%. Otherwise it’s taxed at ordinary income rates.
The second tier is where non-dividend distributions live. Once E&P is used up, further dollars are a non-taxable return of capital. They reduce your adjusted basis in the stock dollar for dollar, and you owe no tax on them in the year you receive them.
The third tier kicks in only if the non-dividend amount is larger than your remaining basis. Basis can’t go below zero, so anything past that point is treated as a capital gain from the sale of stock. If you’ve held the shares more than a year, it qualifies for long-term capital gains rates.3Internal Revenue Service. Topic No. 409 – Capital Gains and Losses
Tier 2 defers tax, it doesn’t erase it. Every dollar that reduces your basis today will show up as a larger capital gain when you eventually sell the shares.
A Worked Example
Say you own 1,000 shares you bought for $15,000, and the company distributes $30,000 to you. The company’s total E&P is only $10,000.
The first $10,000 matches E&P and is a taxable dividend. The next $15,000 has no E&P behind it, so it’s a return of capital that reduces your basis from $15,000 to zero. The final $5,000 has nowhere left to go — basis is already at zero — so it’s a capital gain, taxed at long-term rates if you’ve held the shares more than a year.4eCFR. 26 CFR 1.301-1 – Rules Applicable With Respect to Distributions of Money and Other Property
End result: $10,000 dividend income, $15,000 tax-free, $5,000 capital gain. Your new basis is zero, which means every future non-dividend distribution from this stock will trigger a capital gain immediately.
Where Non-Dividend Distributions Usually Come From
Most shareholders run into these payments through ordinary investments rather than through closely held stock.
REITs
Real estate investment trusts are the most common source. Because REITs take large depreciation deductions on the properties they own, their E&P is often well below the cash they pay out. The excess shows up in Box 3 of your 1099-DIV. Part of what looks like a high REIT yield is really your own capital coming back to you.
Mutual Funds
Funds that target a fixed monthly payout sometimes distribute more than they earn in net investment income and realized gains. The overage is a return of capital, reported the same way in Box 3 and reducing your basis just as REIT distributions do.5Internal Revenue Service. Publication 550 – Investment Income and Expenses Several years of these payments can quietly erode your basis, leaving a bigger-than-expected capital gain waiting when you sell.
Reporting It on Your Tax Return
The Box 3 amount on Form 1099-DIV is labeled “return of capital.”6Internal Revenue Service. Form 1099-DIV – Dividends and Distributions You don’t enter it as income on Form 1040. Nothing gets filed for the basis reduction itself; you just update your own records to lower the adjusted basis of the shares by that amount.5Internal Revenue Service. Publication 550 – Investment Income and Expenses
If the Box 3 amount is larger than your remaining basis, the excess is a capital gain. Report it on Form 8949 and carry the total to Schedule D. Use Part I for shares held one year or less and Part II for shares held more than a year.7Internal Revenue Service. Instructions for Form 8949
Tracking Your Basis Over Time
The IRS puts basis tracking on you. Brokerages report cost basis on shares acquired after certain dates, but they generally don’t adjust that figure for non-dividend distributions. If you don’t keep your own running total, you’ll overstate your basis at sale, understate your gain, and risk penalties on the underpayment.
If you bought shares in multiple lots and can’t identify which lot received the distribution, IRS Publication 550 says to reduce the basis of your earliest purchases first.5Internal Revenue Service. Publication 550 – Investment Income and Expenses Those oldest lots often already have the lowest remaining basis, so they’re the ones most likely to hit zero and start generating taxable capital gains.
Starting basis matters too. For gifted shares, your basis is generally the donor’s basis, not the fair market value on the date of the gift.8Office of the Law Revision Counsel. 26 U.S. Code 1015 – Basis of Property Acquired by Gifts and Transfers in Trust Inherited shares get a stepped-up basis equal to fair market value on the date of death. A simple spreadsheet with each lot’s purchase date, cost, and cumulative Box 3 amounts, updated when your 1099-DIV arrives, is enough.
The 3.8% Net Investment Income Tax
The dividend portion and any capital gain can also be hit with the 3.8% net investment income tax if your modified adjusted gross income tops the threshold. For 2026 the thresholds are $250,000 for married filing jointly, $200,000 for single filers, and $125,000 for married filing separately.9Internal Revenue Service. Topic No. 559 – Net Investment Income Tax These are fixed by statute and don’t adjust for inflation.
The Tier 2 portion that just reduces your basis doesn’t trigger NIIT in the year you receive it. But the eventual sale gain, inflated by years of basis reductions, does count as net investment income. Trusts and estates cross the NIIT threshold at roughly $16,000 for 2026, so trust-held REITs and funds are worth watching closely.
S Corporation Distributions Work Differently
If you’re looking at a distribution from an S corporation, the framework above doesn’t apply the same way. An S corporation that has never been a C corporation generally has no accumulated E&P, so the dividend tier drops out. Distributions come first from the accumulated adjustments account, tracking income shareholders have already been taxed on through the pass-through return, and reduce basis rather than producing dividend income.10Internal Revenue Service. Distributions With Accumulated Earnings and Profits Amounts beyond your remaining basis become a capital gain, the same Tier 3 result. An S corporation with leftover C-corporation E&P is a more complicated case with its own ordering rules.
