A consolidated 1099 tax statement is a single year-end packet your brokerage or financial institution sends that bundles all of your investment-related IRS information returns into one document. Instead of a separate envelope for interest, dividends, and every stock sale, you get one report covering the whole account. You do not send the packet itself to the IRS; you use it as the source document for filling in the schedules attached to your Form 1040.
What’s Actually Inside the Packet
The consolidated statement is not an official IRS form. It’s a convenience document your brokerage builds by combining several separate 1099s that would otherwise arrive as individual forms. The institution files each of those component forms with the IRS on its own; your copy is stitched together for readability.
Which forms appear depends on what happened in your account during the year. The common components:
- Form 1099-INT reports interest from bank accounts, CDs, corporate bonds, and Treasuries. Box 1 is taxable interest; Box 8 is tax-exempt interest from sources like municipal bonds. Tax-exempt interest isn’t subject to federal income tax, but it still has to be reported because it feeds the formula that decides whether Social Security benefits become partially taxable.1Internal Revenue Service. Instructions for Forms 1099-INT and 1099-OID (01/2024)2Social Security Administration. Must I Pay Taxes on Social Security Benefits?
- Form 1099-DIV covers dividends and mutual fund distributions. Box 1a is total ordinary dividends; Box 1b breaks out the portion that’s “qualified.” Qualified dividends are taxed at long-term capital gains rates, ordinary dividends at your regular rate. Box 2a reports capital gain distributions from mutual funds, taxed as long-term regardless of how long you’ve held the fund.3Internal Revenue Service. Instructions for Form 1099-DIV (01/2024)4Internal Revenue Service. Topic No. 404, Dividends and Other Corporate Distributions
- Form 1099-B lists every sale of stocks, bonds, mutual fund shares, and options. This is usually the longest section and the one most likely to cause reporting mistakes.
- Form 1099-OID shows imputed interest on bonds purchased at a discount, income you owe tax on even though no cash changed hands.1Internal Revenue Service. Instructions for Forms 1099-INT and 1099-OID (01/2024)
- Form 1099-MISC catches income that doesn’t fit the interest and dividend boxes. Royalties of $10 or more are the common example.5Internal Revenue Service. About Form 1099-MISC, Miscellaneous Information
- Form 1099-R may be included if the same institution handles your retirement accounts. It reports distributions from IRAs, 401(k)s, pensions, and annuities, with a code identifying the type of withdrawal.6Internal Revenue Service. About Form 1099-R, Distributions From Pensions, Annuities, Retirement or Profit-Sharing Plans, IRAs, Insurance Contracts, etc.
Consolidated statements are issued for taxable, non-retirement investment accounts. Traditional IRAs and Roth IRAs don’t produce a consolidated 1099 for the trading activity inside them, because that activity isn’t taxed as it happens.
When It Arrives
Expect your consolidated 1099 later than your other tax documents. Employers have to send W-2s by January 31, but brokerages have until February 15 to deliver consolidated statements that include Form 1099-B (or the new Form 1099-DA). When February 15 lands on a weekend or holiday, the deadline shifts to the next business day.7Internal Revenue Service. General Instructions for Certain Information Returns (2025)
The extra time exists because institutions need final figures on corporate actions, mutual fund reclassifications, and REIT distributions before they can produce the statement. Corrected versions arriving in March or April are common for the same reason.
If you haven’t received your statement by late February, contact the brokerage first; most firms can reissue or point you to a digital copy. If the institution doesn’t respond, the IRS will reach out to the payer on your behalf if you call 800-829-1040 after the end of February.8Internal Revenue Service. What to Do When a W-2 or Form 1099 Is Missing or Incorrect If the filing deadline is close, you can file using your best estimates from your own account records and file Form 1040-X to amend once the real numbers arrive.9Internal Revenue Service. Topic No. 154, Form W-2 and Form 1099-R (What to Do if Incorrect or Not Received)
Reading the 1099-B Section
Form 1099-B is where most reporting mistakes happen. Each row is a single sale, and each sale has to be classified two ways: by holding period and by whether the cost basis was reported to the IRS.
Covered vs. Non-Covered Securities
A “covered” security is one your broker is required to track cost basis for and report to the IRS. Congress phased the requirement in over several years:10Internal Revenue Service. Instructions for Form 1099-B (2026)
- Stocks purchased after 2010 (after 2011 for mutual fund shares and other securities using the average basis method).
- Bonds, options, and securities futures contracts acquired after 2013, for most types.
- More complex instruments (convertible bonds, inflation-indexed debt, certain foreign-currency options) acquired after 2015.
For a covered security, the basis appears on your 1099-B and is filed with the IRS. For a non-covered security (typically something you bought years earlier), the basis box will be blank or marked as not reported, and figuring out what you originally paid falls to you. Old trade confirmations and account statements are the usual source. Getting this number wrong means either overpaying tax or understating a gain the IRS can later catch.
Short-Term vs. Long-Term
Every transaction is tagged short-term or long-term based on how long you held the asset. One year or less is short-term, taxed at ordinary income rates. More than a year is long-term, eligible for the preferential capital gains rates.11Internal Revenue Service. Topic No. 409, Capital Gains and Losses Your 1099-B shows both dates, so you can check the categorization yourself.
Wash Sale Adjustments
If you sold a security at a loss and bought a substantially identical one within 30 days before or after the sale, the loss is disallowed under the wash sale rule.12Office of the Law Revision Counsel. 26 USC 1091 – Loss From Wash Sales of Stock or Securities Your broker flags these on the 1099-B and adds the disallowed loss to the basis of the replacement shares. Skipping over that adjustment is one of the easiest ways to accidentally overstate losses and pull an IRS notice.
Where Each Section Flows on Your Return
Tax software handles the mechanics if you import the statement, but the mapping is worth knowing so you can spot errors.
Schedule B: Interest and Dividends
Taxable interest from your 1099-INT and ordinary dividends from your 1099-DIV go on Schedule B. You’re required to file Schedule B if your taxable interest or ordinary dividends exceed $1,500, if you had a foreign financial account, or if you received a distribution from a foreign trust.13Internal Revenue Service. Schedule B (Form 1040) 2025 – Interest and Ordinary Dividends The totals move to the matching lines on Form 1040.
Form 8949 and Schedule D: Investment Sales
Every 1099-B transaction goes on Form 8949, grouped by whether the basis was reported to the IRS and whether the gain is short-term or long-term.14Internal Revenue Service. About Form 8949, Sales and Other Dispositions of Capital Assets Your 1099-B includes a checkbox code (A, B, or C for short-term; D, E, or F for long-term) telling you exactly which section of Form 8949 each row belongs in.10Internal Revenue Service. Instructions for Form 1099-B (2026) Totals from Form 8949 flow to Schedule D, which nets everything out and sends the final capital gain or loss to your Form 1040.15Internal Revenue Service. Instructions for Form 8949 (2025)
If your sales produced a net loss for the year, you can deduct up to $3,000 against other income ($1,500 if married filing separately), and losses beyond that carry forward to future years indefinitely.16Office of the Law Revision Counsel. 26 USC 1211 – Limitation on Capital Losses11Internal Revenue Service. Topic No. 409, Capital Gains and Losses
The Supplemental Information Section
Most consolidated statements finish with a supplemental section that doesn’t correspond to any single IRS form. Read it. This is where you’ll find foreign taxes paid on international investments (which may earn you a credit on Form 1116 or a direct deduction), accrued market discount on bonds, and tax-exempt interest broken down by state. The state breakdown matters because most states tax interest from municipal bonds issued by other states, even though that interest is federally exempt. These details are easy to miss, and missing them costs money.
One more item that isn’t on your consolidated 1099 but relates to what it reports: high-income investors owe an additional 3.8% net investment income tax on interest, dividends, capital gains, rental income, and royalties when modified adjusted gross income exceeds $200,000 (single) or $250,000 (married filing jointly). You calculate it separately on Form 8960.17Internal Revenue Service. Topic No. 559, Net Investment Income Tax
When You Get a Corrected Statement
Corrected consolidated 1099s are common and often arrive weeks after the original. Mutual funds and REITs that reclassify distributions after the initial mailing are the usual reason. A corrected statement is labeled “CORRECTED” and carries updated figures for the affected component forms.
If you’ve already filed and the new numbers change your tax liability, file Form 1040-X to report the correct figures.9Internal Revenue Service. Topic No. 154, Form W-2 and Form 1099-R (What to Do if Incorrect or Not Received) The IRS receives the corrected data too, and mismatches generate automated notices, so don’t ignore meaningful differences.
If you think the statement is genuinely wrong rather than just reclassified, take it up with your brokerage; the institution is responsible for issuing the corrected form. Cost basis errors are especially worth pushing on, because an incorrect basis carries all the way through Form 8949 and Schedule D and distorts the gain you report.
A Note on Digital Assets
Starting with 2026 transactions, brokers report digital asset sales on the new Form 1099-DA rather than on Form 1099-B.18Internal Revenue Service. About Form 1099-DA, Digital Asset Proceeds From Broker Transactions If your brokerage handled cryptocurrency or other digital asset trades, expect that form in the consolidated packet. Basis reporting is required for digital assets that are covered securities but not for non-covered digital assets, so the same “who tracked the basis” question applies.19Internal Revenue Service. 2026 Instructions for Form 1099-DA (Draft) Digital asset transactions flow to Form 8949 and Schedule D the same way stock sales do.
