Form 1099-B Tax Year 2011 Filing Checklist
Overview and Context
Form 1099-B for tax year 2011 represents a landmark transition in broker reporting requirements. This year marked the first implementation of mandatory cost basis reporting under the Emergency Economic Stabilization Act of 2008.
Brokers became required to report not only gross proceeds but also cost basis information for covered securities, fundamentally changing how investors track and report capital gains and losses. The 2011 form introduced new boxes for acquisition dates, cost basis, wash sale adjustments, and gain or loss classifications that significantly enhanced IRS oversight of securities transactions.
What Is Form 1099-B
Form 1099-B reports proceeds from broker and barter exchange transactions. Brokers must file this form for each person who sold stocks, bonds, commodities, regulated futures contracts, foreign currency contracts, or exchanged property through barter exchanges.
The form captures sales proceeds and, beginning in 2011 for covered securities, the cost basis and other transaction details needed to calculate taxable gains or losses accurately.
Covered vs Noncovered Securities
Understanding the distinction between covered and noncovered securities is critical for 2011 reporting.
Covered securities include stock acquired for cash in accounts after December 31, 2010. When brokers report covered securities, they must complete Box 1b showing the acquisition date, Box 3 showing the cost basis, Box 5 showing any wash sale loss disallowance, and Box 8 indicating whether the gain or loss is short-term or long-term.
Noncovered securities include stock acquired before January 1, 2011, stock in most mutual funds and regulated investment companies, and stock held in dividend reinvestment plans as of the end of 2011. For noncovered securities, brokers may check Box 6 and leave basis-related boxes blank. Recipients remain responsible for determining and reporting the cost basis of noncovered securities using their own records.
Ten-Step Recipient Checklist
Step 1: Verify Payer and Recipient Information
Review the payer’s name, address, and federal identification number at the top of the form. Ensure that your name, address, and taxpayer identification number are accurately displayed in the recipient section.
Copy B may show only the last four digits of your TIN for privacy protection, but Copy A, sent to the IRS, contains your complete TIN. Contact your broker immediately to correct any errors, as incorrect information can trigger backup withholding or delay processing of your tax return.
Step 2: Gather All Forms 1099-B
Collect every Form 1099-B you receive for the 2011 calendar year. Brokers generally must furnish these forms by January 31, 2012, with a possible extension to February 15, 2012, for transactions involving covered securities.
If you maintain multiple brokerage accounts, you will receive separate forms from each broker. Review account numbers shown on each form to distinguish between different accounts or transaction types. Organize forms by payer to facilitate accurate Schedule D reporting.
Step 3: Review Transaction Dates and Security Details
Locate the sale or exchange date shown in Box 1a. This represents the trade date for broker transactions or the date you received cash, property, credit, or scrip for barter exchanges.
For short sales, Box 1a shows the date you delivered securities to close the short position. Check Box 1b for the acquisition date, though this box may be blank if Box 6 is checked or if you acquired securities on multiple dates. Review Box 9 for transaction descriptions and the CUSIP number field, which provides security identifiers to help match forms to your records.
Step 4: Record Gross Proceeds
Box 2 shows the aggregate cash proceeds from your transactions. Brokers may report gross proceeds or gross proceeds reduced by commissions, transfer taxes, and option premiums, depending on their record-keeping methods. The form indicates which approach was used by checking boxes within Box 2.
Box 2 does not include accrued interest on bonds, which appears separately on Form 1099-INT. For corporate acquisitions or capital structure changes, Box 2 may show the fair market value of cash and other property received. Record the Box 2 amount for each transaction in Schedule D.
Step 5: Identify Bartering Income and Backup Withholding
If you participated in barter exchanges, Box 14 shows the fair market value of property, services, trade credits, or scrip you received. This amount represents taxable ordinary income that must be reported even though you received no cash.
Box 4 shows that federal income tax is withheld through backup withholding. Backup withholding occurs at a rate of 28 percent when you fail to provide your TIN or the IRS notifies the broker of TIN discrepancies. Include any backup withholding shown in Box 4 as tax withheld on your Form 1040.
Step 6: Determine Cost Basis
Review Box 3 for cost or other basis information. If Box 6 is checked, indicating a noncovered security, Box 3 may be blank, and you must determine the basis from your records.
For covered securities purchased in 2011, brokers report the adjusted basis, which includes the purchase price plus commissions and transfer taxes. Gather your purchase confirmations, monthly statements, and transaction records to calculate the basis for noncovered securities. Special rules apply for gifts, inheritances, stock splits, and reorganizations.
Step 7: Calculate Section 1256 Contract Results
If you traded regulated futures contracts or foreign currency contracts, review Boxes 10 through 13. Box 10 shows profit or loss realized on contracts closed during 2011. Box 11 shows adjustments for open contracts held at the start of 2011.
Box 12 shows unrealized profit or loss on contracts still open as of December 31, 2011, which are marked to market as if they were sold. Box 13 aggregates these amounts to show your total gain or loss.
Section 1256 contracts receive special treatment, with 60 percent of the gain or loss treated as long-term and 40 percent as short-term, regardless of the actual holding period. Transfer Box 13 totals to Form 6781 to calculate your Section 1256 contract results.
Step 8: Compile Supporting Documentation
Maintain comprehensive records for all securities transactions. Keep broker statements, trade confirmations, monthly and annual account statements, and purchase records that show the dates acquired and amounts paid.
Retain dividend reinvestment plan statements showing shares acquired through reinvested dividends. Store records of corporate actions, including mergers, stock splits, and reorganizations, that affect the basis.
IRS guidelines recommend retaining tax records for three years from the date of filing or two years from the date of payment, whichever is later. For securities records, retain documentation for three years after you report the disposition on your tax return. Complex situations may warrant longer retention periods.
Step 9: Complete Schedule D and Form 6781
Use information from all Forms 1099-B to prepare Schedule D of Form 1040. Separate transactions into short-term capital gains and losses for assets held one year or less and long-term capital gains and losses for assets held more than one year.
For each transaction, report the description, dates acquired and sold, proceeds, cost basis, and gain or loss. Check Box 8 on Form 1099-B to determine whether transactions should be reported as short-term or long-term, though this box may be blank for noncovered securities.
If you have Section 1256 contract activity shown in Boxes 10 through 13, complete Form 6781 first and transfer the results to Schedule D. Do not attach Forms 1099-B to your tax return.
Step 10: Review, Sign, and File
Verify all information transferred accurately from Forms 1099-B to Schedule D and Form 6781. Ensure that transactions are classified correctly as short-term or long-term based on acquisition and sale dates. Reconcile totals to ensure all transactions are reflected.
Review wash sale adjustments shown in Box 5 and ensure that the basis of replacement securities has been increased appropriately. Sign your Form 1040 certifying the information is correct and complete. File according to IRS instructions and retain Copy B of all Forms 1099-B with your tax records for the required retention period.
Form-Specific Considerations
Nonresident Alien Reporting
Nonresident aliens may be subject to withholding on certain transactions. Brokers may file Form 1042-S rather than Form 1099-B for foreign individuals. Tax treaties may reduce or eliminate withholding obligations. Nonresident aliens should consult Publication 515 for guidance on withholding requirements and treaty provisions.
Cost Basis Documentation Requirements
When brokers fail to report the cost basis for noncovered securities, recipients are responsible for substantiation. Maintain detailed records showing acquisition date, number of shares purchased, purchase price per share, total cost including commissions, and adjustments from corporate actions.
For inherited securities, obtain documentation of fair market value on the date of death. For gifted securities, secure records of the donor’s original basis and acquisition date. Adequate records ensure accurate reporting of gains and losses.
Capital Loss Limitations
Capital losses offset capital gains without limitation. After offsetting capital gains, taxpayers may deduct up to $3,000 of net capital loss against ordinary income. Married taxpayers filing separately may deduct up to $1,500 each.
Capital losses exceeding these limits carry forward indefinitely, preserving their character as short-term or long-term losses. Track carryforwards carefully and report them on Schedule D of your current year return.
Filing Deadlines and Requirements
Brokers must furnish Form 1099-B Copy B to recipients by January 31, 2012, or February 15, 2012, for certain covered securities transactions. Brokers file Copy A with the IRS by February 28, 2012, or April 2, 2012, if filing electronically.
Recipients use the information to complete their Form 1040 tax returns, due April 17, 2012, for the 2011 calendar year. Extensions are available using Form 4868, which extends the filing deadline to October 15, 2012, though tax payments remain due by the original April deadline.
