Form 1040

3b — Ordinary Dividends Updated for tax year 2025

What this line means

The total of all dividends you received during the year, including both qualified dividends (line 3a) and non-qualified dividends. This is the full dividend amount from Box 1a of all your 1099-DIV forms combined. Non-qualified dividends are taxed at your ordinary income rate; the qualified portion gets the lower capital gains rate.

Does this apply to you?

  • You received dividends from any stock, mutual fund, or ETF held in a taxable account
  • You own shares in REITs that paid distributions during the year
  • You received a 1099-DIV from your brokerage with an amount in Box 1a
  • You hold money market funds in a taxable brokerage account that paid dividends

Easy to overlook

Reinvested dividends are still taxable If your brokerage account automatically reinvests your dividends to buy more shares, those dividends are still taxable in the year they were paid. The reinvestment does not defer the tax. Your 1099-DIV reports the full amount regardless of whether you took the cash or reinvested it. Many filers assume reinvested dividends are not taxable until they sell. 1 [SOURCE: CP2000 pattern — unreported dividends from reinvested distributions]

Capital gain distributions are not on this line Your 1099-DIV Box 2a shows capital gain distributions from mutual funds. These go on line 7a (capital gain or loss), not here. Only Box 1a ordinary dividends go on line 3b. Mixing these up double-reports income or puts it on the wrong line, triggering IRS matching issues. 2 [SOURCE: IRS Publication 550 — Investment Income and Expenses]

Watch out for this

Reporting only the non-qualified portion on line 3b. Line 3b is your total ordinary dividends — it includes both the qualified and non-qualified amounts. Line 3a (qualified dividends) is a subset, not a separate category. If your 1099-DIV shows $1,000 in Box 1a total and $800 in Box 1b qualified, line 3b is $1,000 and line 3a is $800.

  • Line 3a — Form 1040 — Qualified dividends; a subset of line 3b taxed at lower rates
  • Schedule B — Form 1040 — Required if ordinary dividends exceed $1,500
  • Line 7a — Form 1040 — Capital gain or loss; mutual fund capital gain distributions go here, not line 3b
