Box 5 on Form 1099-DIV reports Section 199A dividends, a portion of your ordinary dividend income that qualifies for a 20% federal tax deduction. The amount comes almost entirely from real estate investment trusts held inside the mutual funds and ETFs in your account, and you claim the deduction on Form 8995 or Form 8995-A when you file.1Internal Revenue Service. Form 1099-DIV – Dividends and Distributions
What the Box 5 Amount Represents
Section 199A dividends are a subset of the ordinary dividends shown in Box 1a on the same form. They are not qualified dividends (Box 1b), which are taxed at long-term capital gains rates. Section 199A dividends are taxed at your ordinary income rate, but the 20% deduction reduces the amount of that income actually subject to tax.1Internal Revenue Service. Form 1099-DIV – Dividends and Distributions
The name traces to Internal Revenue Code Section 199A, the qualified business income provision created by the Tax Cuts and Jobs Act of 2017.2Office of the Law Revision Counsel. 26 USC 199A – Qualified Business Income
Where the Income Comes From
A REIT distributes most of its taxable income to shareholders, and the portion that isn’t a capital gain distribution or qualified dividend income meets the statutory definition of a qualified REIT dividend.3Legal Information Institute. 26 USC 199A(e)(3) – Qualified REIT Dividend Most investors hold REITs through mutual funds or ETFs rather than directly. Those funds pass the character of the REIT dividends through to shareholders, and the qualifying portion lands in Box 5 of your 1099-DIV.4Internal Revenue Service. Instructions for Form 1099-DIV
Publicly traded partnership income can also feed Box 5 when a fund holds PTP interests. Direct PTP investors typically see this income on a Schedule K-1 instead.
How the 20% Deduction Works
You deduct 20% of the Box 5 amount from your taxable income. A $10,000 Box 5 figure produces a $2,000 deduction, which saves tax at your marginal rate.2Office of the Law Revision Counsel. 26 USC 199A – Qualified Business Income
This is a below-the-line deduction. It reduces taxable income after AGI is calculated, and you get it whether you take the standard deduction or itemize.5Internal Revenue Service. Qualified Business Income Deduction
Box 5 income falls under the REIT/PTP component of Section 199A, which is separate from the QBI component for business owners. The W-2 wage limitation and qualified property basis limitation that can shrink the QBI deduction for high earners do not apply here.5Internal Revenue Service. Qualified Business Income Deduction The only cap is an overall one: your total Section 199A deduction can’t exceed 20% of taxable income minus net capital gains.2Office of the Law Revision Counsel. 26 USC 199A – Qualified Business Income
Which Form to Use
The form depends on your taxable income before the QBI deduction. For 2026, the thresholds are $201,750 for single filers and $403,500 for joint filers.6Internal Revenue Service. Instructions for Form 8995
- Form 8995 is the simplified version for taxpayers at or below those thresholds. Enter the Box 5 amount on Line 6 (qualified REIT dividends and PTP income), and the form applies the 20% multiplier on Line 9.7Internal Revenue Service. Form 8995 – Qualified Business Income Deduction Simplified Computation
- Form 8995-A is required above the thresholds. If your only Section 199A income is from Box 5, you can skip Parts I through III and go straight to Part IV for the REIT/PTP component.8Internal Revenue Service. Instructions for Form 8995-A – Qualified Business Income Deduction
The final deduction from either form flows to Form 1040, Line 13a.9Internal Revenue Service. Instructions for Form 8995
Do You Actually Qualify? Check the Holding Period
An amount in Box 5 does not automatically mean you get the deduction. You must have held the fund shares for at least 46 days during the 91-day window that begins 45 days before the fund’s ex-dividend date. The count starts the day after purchase and includes the day of sale.
Fund companies report Box 5 without regard to how long you held the shares. Confirming that you met the holding period is on you. Investors who trade around distribution dates often miss this and either forfeit a legitimate deduction or claim one they aren’t entitled to.
Reporting the Dividend Income Itself
The Box 1a total, which already includes the Box 5 amount, goes on Form 1040, Line 3b.1Internal Revenue Service. Form 1099-DIV – Dividends and Distributions Schedule B is required if total ordinary dividends exceed $1,500.10Internal Revenue Service. Schedule B (Form 1040) – Interest and Ordinary Dividends Box 5 is not reported separately as income; the deduction is the only place it does independent work on your return.
High-Income Investors Aren’t Phased Out
The income thresholds that dominate most Section 199A discussions apply to the QBI component for trade or business income, not to REIT/PTP income. Someone earning $1 million gets the full 20% deduction on Box 5 dividends, same as someone earning $50,000, limited only by the overall cap tied to taxable income minus net capital gains.2Office of the Law Revision Counsel. 26 USC 199A – Qualified Business Income Box 5 income is one of the most reliably deductible categories under Section 199A at any income level.
State Taxes Often Don’t Follow
Many states do not conform to the federal Section 199A deduction. In those states, the full Box 5 amount is taxable with no 20% reduction. A few states have their own version, but conformity varies. Check your state’s rules before assuming the federal savings carry through.
The Deduction Is Permanent
Section 199A was originally scheduled to sunset after December 31, 2025, which would have eliminated the Box 5 deduction starting with the 2026 tax year. The One Big Beautiful Bill Act, signed into law on July 4, 2025, removed that sunset and made the deduction permanent.11United States Congress. H.R.1 – 119th Congress – One Big Beautiful Bill Act The 20% reduction on Section 199A dividends continues indefinitely.
