Do I have to report interest under $10 if I never got a 1099-INT?

Yes. Payers are only required to issue Form 1099-INT once interest reaches $10 for the year, but the income is taxable from the first dollar. The reporting threshold applies to the payer, not to you. Check your year-end bank statements for small amounts that never generated a form.

Why are my qualified dividends in box 1b also included in box 1a?

Box 1a is the total of all ordinary dividends, and box 1b tells you how much of that total qualifies for preferential long-term rates. Box 1b is a subset of box 1a, not a separate amount. Adding them together double counts your dividend income and inflates your taxable income.

Is tax-exempt interest really tax free?

It is free of federal income tax, but it is not invisible. Tax-exempt interest in box 8 counts toward the provisional income calculation that determines how much of your Social Security is taxable, and it feeds the modified adjusted gross income figures behind Medicare premium surcharges.

What is a nondividend distribution in box 3 of Form 1099-DIV?

A nondividend distribution is a return of your own invested capital rather than a share of profits. It is not taxable in the year received, but it reduces your cost basis in the investment. When you eventually sell, the lower basis produces a larger capital gain, so the tax is deferred rather than eliminated.

What are Section 199A dividends in box 5?

Box 5 reports the portion of REIT dividends eligible for the qualified business income deduction, which can shelter a share of that income from tax. It requires no business ownership and no phase-out testing at the individual level for this component. It is one of the most commonly missed entries on a brokerage 1099.

IRS Form Guides>1099-INT vs 1099-DIV

Written by Bryan Martin, CPA, Managing Partner and Founder of Taxstra. Last updated August 15, 2026.

Quick answer

Form 1099-INT reports interest earned from lending money, taxed at ordinary income rates up to the top bracket. Form 1099-DIV reports dividends earned from owning equity, where qualified dividends receive lower long-term capital gains rates. The distinction can change the tax on the same dollar by roughly half.

The difference between these two forms is not administrative. It is the difference between income taxed at your top marginal rate and income taxed at preferential capital gains rates. On the same dollar, that gap can approach half the tax.

Interest is what you earn as a lender. Dividends are what you earn as an owner. The tax code rewards ownership, and the two forms exist to keep the categories apart.

The Core Difference

Lender income versus owner income, and why the rates diverge.

	Form 1099-INT	Form 1099-DIV
Your role	Lender	Owner
Typical sources	Savings accounts, CDs, Treasury bills, corporate bonds, money market funds	Stocks, mutual funds, ETFs, REITs
Federal rate	Ordinary income rates	Long-term capital gains rates on the qualified portion
State treatment	Treasury interest is state exempt; bank interest is not	Generally taxable, with municipal fund exceptions
Issuing threshold	$10 of interest	$10 of dividends

Why this drives account placement

Because interest is taxed at the highest rates and qualified dividends at the lowest, the natural conclusion is to hold interest-generating assets inside tax-deferred accounts and equities in taxable accounts. That is the core of asset location strategy, and it is free to implement.

Form 1099-INT Box by Box

Seven boxes carry nearly all the real-world consequences.

Box	Reports	What it means
1	Interest income	Ordinary taxable interest from banks, credit unions, and corporate bonds. Taxed at your ordinary income rate.
2	Early withdrawal penalty	Penalty charged for cashing a CD early. This is an above-the-line adjustment, so you get it back against income.
3	Interest on U.S. Savings Bonds and Treasury obligations	Federally taxable but exempt from state and local income tax. Most software handles the state subtraction only if you enter it in box 3.
4	Federal income tax withheld	Backup withholding, usually triggered by a missing or mismatched taxpayer identification number.
8	Tax-exempt interest	Municipal bond interest. Excluded from federal taxable income, but it still counts toward the calculation that taxes Social Security benefits.
9	Specified private activity bond interest	Tax-exempt for regular tax but added back for alternative minimum tax purposes.
13	Bond premium on tax-exempt bond	Reduces the amount of tax-exempt interest you report.

Taxstra CPA Tip

Taxstra Tip

Box 3 is worth checking every year if you hold Treasury bills or savings bonds. Treasury interest is exempt from state and local income tax, but that exemption only reaches your state return if the amount was entered in box 3 rather than lumped into box 1. In a high-tax state this is a real annual leak on an otherwise correct return.

Form 1099-DIV Box by Box

Where the subset relationships confuse even experienced filers.

Box	Reports	What it means
1a	Total ordinary dividends	Every dividend the fund or company paid you. This is the gross number, not the taxable-at-preferential-rates number.
1b	Qualified dividends	The subset of box 1a that qualifies for long-term capital gains rates. Box 1b is included within box 1a, not added to it.
2a	Total capital gain distributions	Gains the fund realized internally and passed through. Taxed at long-term rates even if you held the fund for a week.
2b	Unrecaptured Section 1250 gain	Real estate depreciation recapture passed through by a REIT or fund. Taxed at a higher maximum rate than other long-term gain.
3	Nondividend distributions	Return of your own capital. Not taxable now, but it reduces your cost basis, which increases gain when you sell.
5	Section 199A dividends	REIT dividends eligible for the qualified business income deduction. Frequently missed.
7	Foreign tax paid	Tax withheld by another country. Usually recoverable as a foreign tax credit rather than a deduction.
12	Exempt-interest dividends	Municipal bond interest received through a mutual fund. Federally exempt, and often partly state exempt too.

Watch Out

Box 1b is inside box 1a, not next to it

This is the most frequent hand-entry error on brokerage forms. If box 1a is $10,000 and box 1b is $8,000, you received $10,000 in dividends of which $8,000 gets the lower rate. You did not receive $18,000.

Four Reporting Errors That Cost Money

Each one is common, each one is avoidable.

Skipping box 5 on a REIT holding

Section 199A dividends qualify for the qualified business income deduction. Anyone holding a REIT index fund in a taxable account probably has an amount here, and leaving it out simply overpays.

Deducting foreign tax instead of crediting it

Box 7 foreign tax is generally worth more as a credit, which reduces tax dollar for dollar, than as an itemized deduction, which only reduces taxable income.

Ignoring box 3 basis reductions

Nondividend distributions quietly lower your basis every year. Investors who never track them overstate their gain, and overpay, when they finally sell.

Assuming tax-exempt interest has no effect

Box 8 municipal interest still counts in the provisional income test for Social Security taxation and in the modified AGI figures behind Medicare premium tiers.

If you are consolidating a brokerage 1099 that also includes 1099-B proceeds, the sequencing matters: dividends and interest set your ordinary income floor, and capital gains stack on top at the rates described in the capital gains holding period guide. Investors holding digital assets alongside securities should also review the crypto wash sale rules, and parents funding custodial accounts need the kiddie tax thresholds before the investment income compounds past them.
