Your Fund Mailed Your Own Money Back: How to Read a 19a-1 Notice

A notice arrives saying 98% of this month’s distribution was “return of capital.” The instinct is to panic — the fund is paying me with my own money. Sometimes that’s exactly right. Sometimes it’s a tax-efficiency feature working as designed. The notice alone won’t tell you which, and learning to read it is the difference between a justified hold and a slow bleed.

What a 19a-1 notice actually is

When a fund pays a distribution that it estimates includes return of capital (ROC) — cash beyond what the fund earned in income and realized gains — it sends shareholders a Section 19(a) notice (often called a 19a-1). It breaks the payout into its estimated sources.

The single most important sentence on the notice is the disclaimer. In the words of a real NEOS notice: the figures “are estimates on a book basis, are not being provided for tax reporting purposes and may later be determined to be from taxable net investment income, short-term gains, long-term gains… and return of capital.” The fund then promises a Form 1099-DIV at year-end that governs how you actually report the distribution. So the 19a-1 is an estimate, not your tax document — but it’s the earliest window into where your cash is coming from.

A real notice, line by line

Here is the actual “Estimated Sources of Distribution” table from the NEOS Nasdaq-100 High Income ETF (QQQI), for the distribution payable June 18, 2026:

Read it left to right. Of the $0.6572 paid per share this month, just $0.0140 (2%) is estimated net investment income — the dividends and interest the fund actually earned. The other $0.6432 (98%) is estimated return of capital. Year-to-date the picture is even starker: 99% ROC.

One quirk worth noting: this NEOS notice doesn’t break out short-term vs. long-term realized gains the way some do; it carries a “Prior Year Undistributed Net Investment Income” line instead (here, zero). Notice formats vary by issuer — read the labels, not a template you memorized.

What that 98% does to your cost basis

ROC isn’t taxed in the year you receive it. Instead it lowers your cost basis — the figure the IRS treats as what you paid — and defers the tax until you sell.

Make it concrete. Say you hold 100 shares of QQQI. This month’s ROC of $0.6432 per share is $64.32, and that amount comes off your cost basis. Collect ROC month after month and your basis keeps dropping; the deferred gain you’ll eventually report grows by exactly as much. The tax didn’t vanish — it moved to the day you sell.

Is 98% return of capital bad? It depends — and the notice can’t tell you

This is the part that trips people up. A high ROC percentage is not, by itself, a verdict. ROC can be two completely different things:

• Constructive — the fund passes through value it genuinely earned (often via tax-efficient option strategies) and labels it ROC to defer your tax. The asset base stays intact.
• Destructive — the fund’s distribution rate consistently exceeds what it earns, so it funds the checks out of principal. Returning that money mechanically drops the NAV on the ex-dividend date, shrinking the engine that generates future income.

The 19a-1 reports the label, not which kind you’re holding. The test that separates them lives on a different page: the NAV trend. If a fund pays ROC-heavy distributions while its net asset value holds steady or rises, the payout was earned. If NAV grinds lower year after year, the ROC is destructive.

The cautionary case in plain numbers: a hypothetical $10,000 in QYLD a decade ago collected roughly $14,000 in distributions — yet the position is now worth about $6,500, its NAV having eroded ~35% over the decade. The checks were real; the principal behind them wasn’t holding.

The tax fine print worth knowing

A few mechanics that change the after-tax math:

• Cost basis and the 1099-DIV. The 19a-1 is an estimate; the year-end 1099-DIV is authoritative. ROC there reduces basis rather than being taxed as income — until basis reaches zero, after which further ROC is taxed as gains.
• Section 1256, for index-option funds. QQQI writes options on the Nasdaq-100 index, and funds writing index options get Section 1256 treatment: premiums taxed at a blended 60% long-term / 40% short-term rate regardless of holding period. That’s part of why these funds can characterize so much of a payout as ROC in the first place.
• Rule 19b-1, the structural nudge. SEC Rule 19b-1 generally limits a fund to distributing long-term capital gains just once a year without special relief, so monthly-paying income ETFs lean on ROC to keep the cash flow smooth.

The verdict: how to read your own notice

Return of capital is a label, not a diagnosis. The 19a-1 notice tells you the label; the NAV trend tells you the truth. Read them together and a scary-looking 98% stops being a mystery.
