Form 1099-B Tax Year 2019 Filing Checklist
Overview and Applicability
Form 1099-B for tax year 2019 operates under standard capital gains reporting rules without Economic Impact Payment reconciliation, Affordable Care Act mandate penalties, or Tax Cuts and Jobs Act phase-in changes affecting this form type. The 2019 form requires recipients to report Section 1256 contracts on Form 6781, as per the Box 13 instructions, consistent with prior-year requirements.
No new lines, credits, or deductions unique to 2019 apply to this information return. The form structure and box definitions remain consistent with prior years, maintaining established reporting frameworks for broker and barter exchange transactions.
Programs Not Applicable
No stimulus reconciliation, shared responsibility payments, or form redesigns tied to 2019 legislative changes apply to Form 1099-B. The form continues to focus on the accurate reporting of securities transactions, providing basis information for covered securities, and the proper classification of capital gains and losses under the longstanding tax rules.
Ten-Step Compliance Checklist
Step 1: Verify Identification Information
Confirm that your complete taxpayer identification number was reported to the IRS, even though Copy B shows only the last four digits for privacy protection. Your Social Security Number, Individual Taxpayer Identification Number, Adoption Taxpayer Identification Number, or Employer Identification Number appears in full on Copy A filed with the IRS. Match the account number on the form with your broker's records to ensure accurate identification of your transactions and prevent reporting discrepancies.
Step 2: Obtain and Organize Forms
Collect Copy B from your broker for each account and each transaction reported in 2019. Retain all copies until the statute of limitations expires, typically three years from your filing date. If you received a corrected Form 1099-B with the corrected box checked, replace the prior version entirely and use only the corrected form for filing your tax return. Corrected forms supersede all previous versions and contain the accurate information you must report.
Step 3: Review Transaction Details
Confirm that the description in Box 1a matches your records, including the number of shares and company name. Box 1b, showing the acquisition date, may be blank if Box 5 is checked, indicating non-covered securities, or if securities were acquired on multiple dates. Box 1c shows the trade date of sale or exchange.
For short sales, Box 1c reflects the date the security was delivered to close the position, not the initial date the short sale was opened. Verify these dates align with your broker statements and trade confirmations.
Step 4: Reconcile Proceeds
Verify that Box 1d showing proceeds reflects cash proceeds reduced by commissions and transfer taxes related to the sale. Brokers may report gross proceeds or net proceeds depending on their record-keeping methods, with checkboxes indicating which approach was used.
For reportable changes in control or capital structure transactions, Box 1d includes aggregate cash plus the fair market value of stock or other property you received. Do not include proceeds from regulated futures or Section 1256 option contracts in this reconciliation, as those amounts appear separately in boxes 10 through 13.
Step 5: Verify Basis Information
Review Box 1e for cost or other basis. For covered securities with Box 5 unchecked, brokers are required to report the basis to the IRS. The basis may be blank if Box 5 is checked, indicating non-covered securities. If the basis was adjusted for a non-compensatory option exercised on or after January 1, 2014, the adjustment reflects your option premium as a mandatory requirement. For non-compensatory options exercised before January 1, 2014, basis adjustment remains permissive.
Examine Box 1f for codes indicating special circumstances. Code W indicates wash sale, code C indicates collectibles, and other codes may appear. Refer to Publication 550 if the codes apply to your transaction.
Step 6: Review Adjustments and Classifications
Examine Box 1g for amounts related to disallowed wash sale losses. If Box 1g shows a nondeductible wash sale loss, you cannot claim that loss on your 2019 return. Instead, add the disallowed amount to the basis of the replacement securities you purchased. Review Box 2 to determine whether the transaction is classified as short-term gain or loss, long-term gain or loss, or ordinary income. If the ordinary box is checked, special rules may apply, such as contingent payment debt instrument treatment. Consult Instructions for Form 8949 and Publication 550 for proper handling of ordinary income classifications.
Step 7: Check Special Transaction Indicators
Review Box 8 for the Qualified Opportunity Fund checkbox if applicable. Qualified Opportunity Fund investments receive special deferral and exclusion treatment under Internal Revenue Code provisions. When Box 1f contains code C, the transaction involves collectibles taxed at a maximum rate of 28 percent, rather than the preferential long-term capital gains rates.
Check Box 4 for backup withholding amounts. Include any Box 4 amount on your 2019 Form 1040 as federal income tax withholding. Backup withholding occurs when you fail to provide a valid taxpayer identification number or when the IRS notifies the broker of identification problems.
Step 8: Identify Noncovered Securities
Check Box 5 to determine whether the item is covered or non-covered. When Box 5 is checked, the securities are noncovered and generally include stock purchased before 2011, most mutual fund shares purchased before 2012, stock from dividend reinvestment plans purchased before 2012, debt acquired before 2014, and options granted or acquired before 2014.
For non-covered securities, boxes 1b, 1e, 1f, 1g, and Box 2 may be blank. You must determine and report your own basis and holding period using your purchase records, broker statements, and confirmation slips. Maintain comprehensive documentation to substantiate your basis calculations.
Step 9: Report Section 1256 Contracts
Review boxes 10 through 13 if your form reports regulated futures contracts, foreign currency contracts, or Section 1256 option contracts. Box 10 shows realized profits or losses on contracts closed during 2019.
Box 11 displays the adjustment for open contracts as of December 31, 2018, reconciling the prior year's mark-to-market treatment with actual results. Box 12 shows unrealized profit or loss on contracts still open on December 31, 2019, which are marked to market and treated as closed for tax purposes.
Box 13 displays the aggregate profit or loss, calculated by combining the results from Boxes 10, 11, and 12. Report the Box 13 amount on Form 6781 for 2019, not on Form 8949 or Schedule D. Section 1256 contracts receive special tax treatment, with 60 percent classified as long-term and 40 percent as short-term, regardless of the actual holding period.
Step 10: Report Bartering and File Return
Check Box 14 for bartering income. When Box 14 contains a value, you received cash, property, services, trade credits, or scrip from a barter exchange. Include this amount in your gross income and consult Publication 525 for proper barter income treatment. Bartering income represents taxable ordinary income even when no cash changes hands. Attach Form 1099-B Copy B to your 2019 Form 1040 or other applicable return type if filing by mail.
Report all transactions on Form 8949 with the applicable checkbox indicated on Form 894d. Transfer Form 8949 totals to Schedule D. The Schedule D instructions provide limited exceptions, allowing certain transactions to be reported directly on Schedule D without using Form 8949; however, most taxpayers are required to complete Form 8949. File your complete return by April 15, 2020, or your applicable extension deadline.
Form-Specific Limitations
Nonresident Alien Recipients
Nonresident aliens receiving proceeds from broker transactions may be subject to different withholding and reporting requirements. Your broker may withhold federal income tax and file Form 1042-S instead of or in addition to Form 1099-B. Tax treaty provisions may affect withholding rates and reporting obligations. Consult the Instructions for Form 1042-S and Publication 515 for comprehensive guidance on investment income from U.S. sources and applicable treaty benefits.
Loss Limitations
Review Box 15 carefully. When Box 15 is checked, you cannot take a loss on your tax return based on the gross proceeds reported in Box 1d for reportable changes in control or capital structure. These situations typically involve corporate reorganizations where tax law prohibits the recognition of a loss, despite an apparent economic loss. The broker should provide a separate statement detailing any allowable losses or explaining the corporate action. Follow the guidance in that statement along with Form 8949 and Schedule D instructions when reporting these transactions.
Basis Reporting Responsibilities
For covered securities with Box 5 unchecked, brokers report basis to the IRS in Box 1e, and you should generally use that amount when calculating gain or loss. However, you remain responsible for making adjustments not reflected in the broker’s reporting, such as wash sales involving multiple accounts, gift tax paid on gifted securities, or basis adjustments from corporate actions the broker may not have tracked.
For non-covered securities with Box 5 checked, you bear full responsibility for determining and reporting an accurate basis. Maintain detailed records, including purchase dates, amounts paid, reinvested dividends, stock splits, mergers, and all other events that affect basis.
Direct Schedule D Reporting
The Schedule D instructions identify specific situations where you may report transactions directly on Schedule D without completing Form 8949. These exceptions apply only when certain criteria are met regarding basis reporting and the need for adjustments. Most taxpayers must complete Form 8949 to provide detailed transaction information before transferring totals to Schedule D. When in doubt, complete Form 8949 to ensure proper reporting and create a clear audit trail for IRS verification.
Significant Form Features
Wash Sale Rules
Brokers identify wash sales occurring within a single account and report disallowed losses in Box 1g. A wash sale occurs when you sell securities at a loss and purchase substantially identical securities within 30 days before or after the sale. The loss is temporarily disallowed and added to the basis of replacement securities.
Brokers cannot track wash sales across multiple accounts you maintain with different brokers or even multiple accounts with the same broker. You must review all your trading activity to identify any additional wash sales and make the necessary adjustments.
Collectibles Treatment
Code C in Box 1f indicates collectibles, including art, antiques, stamps, coins, gems, and precious metals. Collectibles gains are taxed at a maximum rate of 28 percent, which is higher than the preferential rates applied to most long-term capital gains. Report collectibles transactions on the appropriate lines of Form 8949 and Schedule D. Consult Publication 550 for comprehensive guidance on collectibles classification and tax treatment.
Code Identification
Box 1f contains codes providing important information about transaction characteristics. Code W indicates wash sale loss disallowance requiring basis adjustment to replacement securities. Code C indicates collectibles subject to special tax rates. Other codes may appear depending on transaction specifics. When codes appear in Box 1f, review the Instructions for Form 1099-B and consult Publication 550 for proper interpretation and tax treatment of coded transactions.
This checklist provides comprehensive guidance for accurately reporting 2019 Form 1099-B transactions, ensuring compliance with IRS requirements and proper treatment of capital gains, losses, and derivative contracts under established tax rules.
