Form 8949 (2019) Checklist
Understanding Form 8949 and Its Purpose
IRS Form 8949 reports sales and dispositions of capital assets held one year or less, classified as short-term, and more than one year, classified as long-term, for the 2019 tax year.
Instructions for 2019 require separate IRS Form 8949 pages for each box checked when multiple reporting statuses apply to your transactions, ensuring basis-reporting alignment with broker-reported Forms 1099-B.
This form allows you and IRS officials to reconcile amounts reported to both parties on Forms 1099-B or substitute statements with amounts you report on your return. You file Form 8949 as an attachment to Schedule D, which itself attaches to Form 1040 as part of your complete tax return package.
Reporting Categories and Box Selection Rules
Part I addresses short-term transactions using boxes A, B, or C, with only one box checked per Part I page. Box A covers short-term transactions reported on Form 1099-B with cost basis reported to the IRS, Box B includes investment transactions without cost basis reported, and Box C captures investment transactions for which you did not receive Form 1099-B.
Each short-term capital gain you report must include the holding period to verify the transaction qualifies as short-term rather than long-term, as your holding period determines whether you recognize short-term gains taxed at ordinary income rates or long-term capital gain taxed at preferential rates. Part II addresses long-term transactions using boxes D, E, or F, with Box D covering transactions with cost basis reported to the IRS, Box E for transactions without basis reported, and Box F for transactions without Form 1099-B.
Exception for Aggregated Reporting Without Form 8949
Instructions for 2019 clarify specific circumstances when you can bypass Form 8949 entirely and aggregate certain transactions to report directly on Schedule D when all conditions apply.
Exception 1 applies only to transactions for which you received Form 1099-B showing that the basis was reported to the IRS with no adjustments in box 1f or 1g. In this case, the Ordinary box in box 2 remains unchecked. You need no adjustments to basis or gain calculations.
Short-term transactions meeting Exception 1 requirements are reported directly on Schedule D, line 1a, without the need for Form 8949 completion, whereas long-term transactions are reported on line 8a. You transfer aggregated short-term gains directly to Form 1040 through Schedule D without itemizing each transaction separately, saving time when you have numerous simple transactions with no wash sales or basis adjustments requiring detailed documentation.
Transaction Entry and Column Completion
You enter description, acquisition date, disposition date, proceeds, cost or other basis, adjustment codes if applicable, and adjustment amounts in columns (a) through (g) for each transaction. The disposition date in column (c) serves as your sale date for holding period calculations and determines whether gains qualify as short-term or long-term.
Proceeds or sales price as reported on Form 1099-B appear in column (d), while cost or other basis as reported to the IRS goes in column (e), and column (g) captures all necessary adjustments to gain or loss calculations, including wash sales adjustments when you repurchase substantially identical securities within thirty days before or after the sale date.
Column (h) calculates gain or loss by subtracting column (e) from column (d) and combining the result with column (g), and each gain or loss calculated in column (h) flows to the appropriate Schedule D line based on which box you checked.
Special Reporting Situations and Adjustments
Corporations and partnerships report undistributed long-term capital gains from Form 2439 on Part II with box F checked, while individuals report Form 2439 amounts directly on Schedule D line 11 rather than on Form 8949. When you receive Form 2439 from a regulated investment company or real estate investment trust, you report the information on your Form 1040 to claim credit for taxes already paid.
Qualified small business stock sold during 2019 may qualify for partial or complete exclusion under Section 1202, with the holding period for qualified small business stock exceeding five years to receive maximum exclusion benefits. QSB stock transactions require documentation showing that the stock met all qualification requirements at issuance and throughout your holding period.
Wash Sales and Disallowed Losses
Wash sales occur when you sell securities at a loss and repurchase substantially identical securities within the prohibited thirty-day window. Brokers typically identify wash sales on Form 1099-B, but you remain responsible for tracking wash sales across multiple accounts or when purchasing securities in retirement accounts.
You enter "W" in column (f) and add the disallowed loss as a positive adjustment in column (g) when reporting wash sales on Form 8949. Understanding wash sales helps you avoid inadvertently triggering disallowance rules that defer loss recognition until you fully dispose of the position and can accurately report the final gain or loss on your investment transactions.
Totals Calculation and Schedule D Transfer
You complete the totals row labeled line 2 for both Part I and Part II by adding amounts in columns (d), (e), (g), and (h), and subtracting negative amounts when applicable. Short-term totals are transferred to Schedule D, line 1b for Box A, line 2 for Box B, and line 3 for Box C. Each short-term capital gain flows through these lines to Form 1040 for inclusion in your overall tax liability calculation.
Long-term totals transfer to Schedule D line 8b for Box D, line 9 for Box E, and line 10 for Box F. You attach all completed Form 8949 pages to Schedule D and verify your taxpayer identification number appears on each page before filing both forms as a single attachment to your 2019 tax return. Your Form 1040 reflects the net capital gain or loss after combining short-term gains, long-term gains, and any applicable exclusions or adjustments.
Year-Specific Requirements for 2019 Filing
Form 8949 for 2019 maintains separate pages for short-term Part I and long-term Part II with identical column structures. Adjustment codes are required in 2019 when the original cost basis differs from the basis reported by the broker. Instructions for 2019 require filers to complete multiple Form 8949 pages when transactions span different reporting-status boxes rather than combining boxes on a single page.
Your completed tax return must include all Form 8949 pages showing transaction details that support your reported capital gains and losses with proper documentation for QSB stock exclusions, wash sales disallowances, and holding period classifications that determine whether transactions generate short-term capital gain or long-term capital gain.
