Form 1099-DIV Explained: Boxes, Qualified Dividends and Who Must File

If you hold shares, funds or an investment account, a 1099-DIV usually arrives early in the year. If you run a corporation that pays dividends, you may be the one who has to issue it. Here's how the IRS instructions break the form down for both sides.

Who must issue a 1099-DIV

Banks and other financial institutions issue most of them, but the rule applies to any payer. The IRS instructions say you file Form 1099-DIV for each person:

• To whom you paid dividends, including capital gain dividends and exempt-interest dividends, and other distributions worth $10 or more
• For whom you withheld federal income tax on dividends under the backup withholding rules
• To whom you paid $600 or more as part of a liquidation

For small company owners, one detail matters: an S corporation reports as dividends on Form 1099-DIV only distributions made out of accumulated earnings and profits. If you're still choosing a structure, my S corp vs LLC guide explains how owners get paid in each.

The boxes that matter most

Box	What it reports
1a, Total ordinary dividends	All ordinary dividends, including net short-term gains from mutual funds and reinvested dividends
1b, Qualified dividends	The part of box 1a eligible for the lower capital gain rates
2a, Total capital gain distributions	Distributions from funds and REITs, always treated as long-term capital gains
3, Nondividend distributions	Return of capital, which isn't a dividend
4, Federal income tax withheld	Backup withholding, if you didn't give the payer your taxpayer number
5, Section 199A dividends	Dividends that may count toward the qualified business income deduction
7, Foreign tax paid	Foreign tax you may be able to claim back
12, Exempt-interest dividends	Tax-exempt interest paid through a mutual fund

Box 1a already includes the qualified amount in box 1b, so don't add the two together. It's an easy mistake to make when you're filling in a return yourself.

Qualified vs ordinary: the 61-day test

All taxable dividends are ordinary income, but qualified dividends get the lower capital gain rates. The payer decides what goes in box 1b, but the holding period still matters. A dividend isn't qualified if you held the share for less than 61 days during the 121-day period that began 60 days before the ex-dividend date. For preferred stock with dividends covering more than 366 days, the test is 91 days in a 181-day window.

So if you bought shares just before a dividend and sold soon after, part of what your 1099-DIV labels qualified may not be qualified for you. Dividends from REITs and some fund distributions generally don't qualify either.

Box 3: why a distribution can lower your cost basis

Nondividend distributions in box 3 are a return of capital: a return of some or all of your investment in the stock. They aren't taxed as dividends, but they reduce your adjusted cost basis, which means a bigger gain when you sell. Track them, because the payer won't do it for you.

Dividends that are really interest

Here's one most people don't know. So-called dividends on share or deposit accounts at credit unions, cooperative banks, savings and loan associations and mutual savings banks are interest, and they're reported on Form 1099-INT, not 1099-DIV.

If you're the payer: W-9s and backup withholding

As of October 2026, the triggers in the current IRS instructions are $10 in dividends and $600 in a liquidation. If a shareholder hasn't given you their taxpayer identification number in the way the rules require, their dividends can be subject to backup withholding, which you report in box 4. The IRS says to use Form W-9 to request the number, or the right Form W-8 for a foreign shareholder. Collect it when someone becomes a shareholder, not in January. You're allowed to truncate the recipient's number on the copy you send them, but never on the copy you file with the IRS.

Deadlines for 2025 forms

Task	Deadline
Send the recipient their copy	31 January
File with the IRS on paper	2 March 2026
File with the IRS electronically	31 March 2026

Since 2024, you must e-file if you have 10 or more information returns of all types combined, not 10 of one type. Paper filers send Form 1096 with the paper forms.

What to do when yours arrives

1. Check your name and taxpayer number, and the payer's details.
2. Enter box 1a as ordinary dividends and box 1b as qualified dividends on your return.
3. If your taxable ordinary dividends are over $1,500, complete Schedule B (Form 1040).
4. Report box 2a capital gain distributions as long-term capital gains.
5. Reduce your cost basis by any box 3 nondividend distributions.
6. If box 4 shows backup withholding, claim it as tax paid, and give the payer your number to stop it.

My verdict

The 1099-DIV looks busy, but most people only need three boxes: 1a, 1b and 2a. The traps are double-counting box 1b, ignoring box 3's effect on your basis, and assuming every qualified dividend qualifies for you when you've traded around the ex-dividend date. If your company pays dividends, the $10 threshold is low, so plan to issue forms every year.
