Form 1040 Schedule D (2019) Tax Checklist Year and Form Attributes
2019 Unique Characteristics
Schedule D for 2019 reflects the Tax Cuts and Jobs Act (TCJA) rules established in 2018, including the expanded three-year holding period for applicable partnership interests under Section 1061, which began in 2018. The 2019 form maintains the Section 121 home sale exclusion of up to $250,000 for single filers or up to $500,000 for married filing jointly filers who meet ownership and use requirements.
Section 1202 qualified small business stock exclusions continue with established rates and thresholds that remain stable from 2018 onward through this period. Capital gain tax rates for 2019 remain at 0%, 15%, and 20% for long-term gains, depending on taxable income thresholds, with special maximum rates of 25% for unrecaptured Section 1250 gain and 28% for collectibles gains.
Year-Specific Programs Applying to 2019 Schedule D
Section 1061 governing the special three-year holding period for applicable partnership interests applies to 2019 and continues from 2018 forward. Taxpayers holding applicable partnership interests, generally those related to the performance of services in a partnership, must determine whether their capital gain holding periods meet the three-year threshold rather than the standard one-year long-term holding period.
This provision primarily affects investment fund managers and certain other service partners. The 2019 instructions do not reflect coronavirus-related relief programs, stimulus reconciliations, or pandemic-specific adjustments, as these were introduced in 2020 and later years.
Ten-Step Checklist for 2019 Schedule D
Step 1: Identify and Gather All Capital Asset Transaction Documents
Collect Form 1099-B showing proceeds and cost basis for securities transactions, Form 1099-S showing proceeds from real estate sales, and Form 1099-DIV showing capital gain distributions in box 2a from mutual funds and other regulated investment companies. Obtain Schedule K-1 from partnerships and S corporations if you received allocations of capital gains or losses.
Gather closing statements for property sales and any other documentation showing acquisition dates, sale dates, and basis adjustments. Verify that all documents show 2019 transaction dates and match your personal transaction records. Organize documents by holding period classification to facilitate Form 8949 completion.
Step 2: Classify Each Transaction as Short-Term or Long-Term and Complete Form 8949
For each capital asset transaction, determine the holding period by counting from the day after acquisition through the day of disposition. Short-term assets are those held one year or less; report these in Form 8949 Part I. Long-term assets are those held more than one year; report these in Form 8949 Part II. For applicable partnership interests acquired under Section 1061, long-term treatment requires holding for more than three years rather than the standard one-year rule.
Complete all Form 8949 columns (a) through (h) for every transaction, including property description, dates acquired and sold, proceeds, cost or other basis, adjustment codes if applicable, adjustments to gain or loss, and the resulting gain or loss. Check the appropriate box at the top of each Form 8949 part (A, B, or C for Part I; D, E, or F for Part II) based on whether the basis was reported to the IRS. Transfer totals to Schedule D only after completing all Form 8949 entries.
Step 3: Report Short-Term Capital Gains and Losses in Part I
Transfer Part I totals from Form 8949 to Schedule D lines 1b for transactions with basis reported to the IRS (Box A checked), line 2 for transactions with basis not reported to the IRS (Box B checked), and line 3 for other short-term transactions not reported on Form 1099-B (Box C checked). Line 1a may be used only for certain covered securities transactions, with no adjustments, allowing for aggregated reporting without the need for Form 8949.
Enter short-term capital loss carryover from your Capital Loss Carryover Worksheet completed for your 2018 return on line 6. Calculate net short-term capital gain or loss on line 7 by combining all Part I lines (lines 1a through 6). This amount represents your total short-term capital gain or loss for 2019.
Step 4: Report Long-Term Capital Gains and Losses in Part II
Transfer Part II totals from Form 8949 to Schedule D lines 8b for transactions with basis reported to the IRS (Box D checked), line 9 for transactions with basis not reported to the IRS (Box E checked), and line 10 for other long-term transactions not reported on Form 1099-B (Box F checked). Line 8a may be used for certain covered securities transactions with no adjustments. Include long-term capital gain or loss from installment sales, like-kind exchanges, or other sources on line 11 as applicable.
Report capital gain distributions from mutual funds shown on Form 1099-DIV box 2a on line 13, regardless of how long you held the fund shares. Enter long-term capital loss carryover from your 2018 Capital Loss Carryover Worksheet on line 14. Calculate net long-term capital gain or loss on line 15 by combining all Part II lines (8a through 14). This amount represents your total long-term capital gain or loss for 2019.
Step 5: Apply the Section 121 Exclusion for Home Sale Gains
If you sold your main home in 2019 and realized a gain, determine eligibility for the Section 121 exclusion. You must have owned and used the home as your principal residence for at least two of the five years preceding the sale date. You must not have excluded gain from another home sale during the two years before this sale. If you meet these requirements, you may exclude up to $250,000 of gain if filing single, head of household, or married filing separately, or up to $500,000 if married filing jointly and both spouses meet the ownership and use tests.
Report the home sale on Form 8949 Part II with code “H” in column (f) to indicate home sale, and enter the excluded portion of the gain as a negative adjustment in column (g). Attach Form 8949 to Schedule D showing the complete gain calculation with the exclusion applied.
Step 6: Apply the Section 1202 Qualified Small Business Stock Exclusion
If you sold qualified small business stock (QSBS) in 2019 that was acquired after August 10, 1993, and held for more than five years, determine your exclusion percentage based on the acquisition date. The exclusion is 50% for stock acquired on or before February 17, 2009; 75% for stock acquired after February 17, 2009, and on or before September 27, 2010; and 100% for stock acquired after September 27, 2010. A C corporation must have issued the stock with total gross assets of $50 million or less at the time of issuance, and you must meet all other QSBS requirements.
Report the sale on Form 8949 Part II with code “Q” in column (f) to indicate qualified small business stock, and enter the excluded portion of the gain as a negative adjustment in column (g). The taxable portion of the gain (if any) may be subject to the 28% collectibles rate. Note that losses from Section 1244 stock should be reported on Form 4797 as ordinary losses, not on Schedule D.
Step 7: Calculate Capital Loss Limitations and Carryover Using the Capital Loss Carryover Worksheet
Combine your net short-term capital gain or loss from line 7 with your net long-term capital gain or loss from line 15, and enter the total on line 16. If line 16 shows a net capital loss, you can deduct only up to $3,000 of that loss on your 2019 Form 1040 or Form 1040-SR (or $1,500 if married filing separately).
If your total capital loss exceeds the annual deduction limit, complete the Capital Loss Carryover Worksheet provided in the Schedule D instructions to calculate the amount of capital loss to carry forward to 2020.
The worksheet separates the carryover into short-term and long-term components, which retain their character in future years. This calculation is mandatory when total losses exceed the annual limit, as unused losses carry forward indefinitely until fully utilized.
Step 8: Attach Form 4952 If Required and Complete Worksheets for Special Gains
If you paid investment interest expense in 2019 and claim a deduction for that expense, you must complete and attach Form 4952 (Investment Interest Expense Deduction) to your return. If line 18 requires completion because you have collectibles gains or Section 1202 gains subject to the 28% maximum rate, complete the 28% Rate Gain Worksheet provided in the Schedule D instructions and enter the result on line 18.
If line 19 requires completion because you have unrecaptured Section 1250 gain from depreciation on real property, complete the Unrecaptured Section 1250 Gain Worksheet and enter the result on line 19. Suppose either line 18 or line 19 contains an amount. In that case, you must complete the Schedule D Tax Worksheet to calculate your tax using the correct blend of ordinary rates, preferential capital gain rates, and special maximum rates for collectibles and unrecaptured depreciation.
Step 9: Verify Form 8949 Completion and Attach to Schedule D
Ensure every Form 8949 page is fully completed with the correct box (A, B, C, D, E, or F) checked at the top of each part to categorize transactions by whether the basis was reported correctly to the IRS and whether adjustments were made. Attach all Form 8949 pages behind Schedule D in the proper sequence, with Part I pages before Part II pages.
Verify that the totals from all Form 8949 pages match the amounts entered on the corresponding Schedule D lines. Double-check that all adjustment codes in column (f) are correct and that all adjustments in column (g) are correctly calculated. If you have transactions that qualify for the exception allowing direct entry on Schedule D lines 1a or 8a without using Form 8949, verify that no adjustments are required and that the basis was reported to the IRS on Form 1099-B for those transactions.
Step 10: Assemble, Sign, and Attach to Form 1040 or 1040-SR with Required Schedules
Arrange all capital gains documents in the proper sequence: Schedule D first, followed by all Form 8949 pages in order, then Form 4952 if applicable, your Capital Loss Carryover Worksheet if you have loss carryovers, the 28% Rate Gain Worksheet if applicable, the Unrecaptured Section 1250 Gain Worksheet if appropriate, and the Schedule D Tax Worksheet if required.
Attach this complete packet to your Form 1040 or Form 1040-SR with the main tax return form on top. Enter the net capital gain or loss from Schedule D line 16 on Form 1040 or Form 1040-SR line 6. Sign and date your return. Do not separate Schedule D from your tax return. If filing by paper mail, consult the IRS Where to File page for Form 1040 for 2019 to determine the correct mailing address based on your state of residence and whether you are enclosing a payment.
Significant Changes for 2019 Schedule D
Holding Period Rules for Applicable Partnership Interests
Before 2018, capital gains from partnership interests held more than one year generally received long-term capital gain treatment. Beginning in 2018 and continuing through 2019, Section 1061 requires that for applicable partnership interests, which are typically partnership interests related to the performance of substantial services in an investment management or similar trade or business, capital gain is treated as long-term only if the interest is held for more than three years, rather than the standard one-year period.
This rule affects carried interest holders and certain other service partners in investment funds. Taxpayers with applicable partnership interests must apply this three-year threshold and may need to complete additional worksheets to characterize their capital gains properly. The three-year holding period applies to both the partnership interest itself and, in some cases, to the holding period of underlying assets.
Form-Specific Limitations for 2019
Nonresident Aliens
Nonresident aliens must use Form 1040-NR (U.S. Nonresident Alien Income Tax Return) instead of Form 1040 or Form 1040-SR. They must report capital gains and losses on Schedule D (Form 1040-NR) according to different rules for taxable and effectively connected income. Capital gains that are not effectively connected with a U.S. trade or business may be exempt from U.S. tax or subject to withholding at treaty rates. Do not file Schedule D (Form 1040) if you are a nonresident alien; use the version designed explicitly for Form 1040-NR.
Capital Loss Deduction Cap
Capital losses are deductible only up to the amount of your capital gains for the year, plus an additional $3,000 if filing single, married filing jointly, or qualifying widow(er), or $1,500 if married filing separately. Excess losses beyond this annual limit must be carried forward indefinitely to future years using the Capital Loss Carryover Worksheet. Carried-forward losses retain their character as short-term or long-term and can be used in the coming years, subject to the same annual limitation. Capital losses cannot be deducted beyond the annual limit in 2019, regardless of the total amount of loss sustained.
Nondeductible Losses
Losses from sales between related parties, as defined in Section 267, are not deductible and must be identified with the code "L" in column (f) of Form 8949. Related parties include family members, controlled corporations, and certain trusts. Losses from wash sales, where you purchase substantially identical securities within 30 days before or after the sale, are not deductible and must be added to the basis of the replacement securities. Losses from personal-use property, such as your personal residence (unless qualifying for casualty loss treatment), personal automobiles, furniture, and other personal assets, are not deductible even if reported on Form 1099-S or Form 1099-B.
You must report these nondeductible losses on Form 8949 and enter code “L” in column (f) to indicate the loss is not allowable. For professional assistance with your 2019 Schedule D capital gains and losses or any tax filing questions, contact our tax experts at (888) 260-9441.
