What Form 1099-B (2018) Is For
Form 1099-B (2018) provides information that helps you calculate capital gains tax for transactions involving capital assets. Brokers issue this form when you sell mutual funds, exchange-traded funds, common stock, or bonds. The form lists gross proceeds and cost information that support accurate reporting of each capital gain.
Form 1099-B also outlines the figures needed to determine capital losses tied to selling securities within a calendar year. Brokers supply these entries so you can combine the reported amounts with your own investment records. These details guide you as you review each capital asset and prepare your filing responsibilities.
When You’d Use Form 1099-B
You use Form 1099-B when brokers report transactions that create net capital gains for the calendar year. These entries influence taxable income because each sale produces taxable gains that must be reported to the IRS. You rely on the form when reviewing income from investments purchased and sold across various accounts.
You also use the form when your activity includes long-term capital gains or short-term capital gains from selling securities. These sales affect how you classify each capital gain within filing statuses such as married filing jointly or married filing separately. These details guide reporting for investment sales.
Key Rules or Details for 2018
The 2018 rules require brokers to classify each transaction so you can identify whether a sale produced a long-term or short-term gain or loss. These rules help you review sales involving precious metals, property held for more than one year, or items treated as ordinary income. Each entry supports accurate reporting when brokers include a CUSIP number for correct identification.
A covered security includes an investment that brokers must track for cost and holding period details. Brokers report these figures so you can determine the correct gain or loss connected to each sale. These requirements guide taxpayers when the wash sale rule applies to substantially identical investments.
Noncovered securities include items that do not require brokers to provide complete basis information. These transactions can require careful review when calculating the correct gain or loss for a non-covered security. These details help you verify entries when the wash sale rule works across multiple accounts and affects future reporting.
Step-by-Step (High Level)
You follow several steps when reviewing Form 1099-B entries to track each gain connected to your personal financial decisions. These steps help you determine how the sale of shares, transfer of property, or exchange of services affects your filing responsibilities. Each step supports accurate reporting when you calculate the correct profit or claim available.
Cost Basis
- You review the cost basis so the calculation reflects the correct gain created when the sale of the same security occurs within the same year.
- You verify each short sale to ensure that the reported figures accurately reflect transactions completed through either a corporate or individual account.
- You compare earlier purchases so future sales help offset capital gains or offset gains tied to other items.
- You evaluate each transaction so the reported profit aligns with the correct rules for property and services.
- You confirm that each line supports accurate reporting when you prepare the form connected to your claim.

Common Mistakes and How to Avoid Them
Many taxpayers face challenges when reviewing each gain or loss reported on Form 1099-B. These issues often involve capital losses, dividends, or values reported for a money market fund. Each situation benefits from careful review when managing the sale of securities or investments purchased during the year.
- Incorrect basis reporting occurs when taxpayers misread figures tied to precious metals or exchange-traded funds. This error becomes less likely when taxpayers compare each basis entry with the information provided on their broker statements.
- Missing sales entries appear when taxpayers overlook smaller transactions in the ordinary course of trading, and this problem becomes less common when taxpayers match every sale to the year-end report.
- Incorrect loss classification occurs when taxpayers report a capital loss instead of a net capital loss. This issue becomes less likely when taxpayers carefully review each calculation.
- Omitted dividends create issues when taxpayers combine multiple accounts, and this issue becomes easier to manage when taxpayers cross-check each account summary.
- Unverified transactions cause problems when reconciliation is skipped, and these errors become less frequent when taxpayers review all items connected to selling securities.

What Happens After You File
The IRS reviews each entry reported to the IRS and compares the amounts with the figures you include for capital assets. The agency evaluates taxable gains, taxable income, and each capital gain to confirm compliance with IRS regulations. This process helps the IRS identify items that require clarification or correction.
Long-term entries appear when your return shows a net capital gain tied to sales taxed under capital gains tax rules. The IRS confirms whether each figure reflects the correct treatment for capital assets subject to review. These steps support accurate processing and guide you through resolving any issues that may arise during evaluation.
FAQs
Do I need to report stock sales that resulted in a capital loss?
You must report every sale that creates a gain or loss because the activity affects your tax return. The IRS uses this information to match entries with records supplied by brokers, and the review is conducted in accordance with IRS regulations. The report also ensures that the correct capital gains tax rules apply to each transaction.
What if my cost basis is missing from a form that lists covered and non-covered securities?
A missing cost basis generally indicates a noncovered security because brokers do not need to track basis for noncovered securities. You still report each capital gain by reviewing your records for an accurate figure. This approach keeps your tax return consistent with IRS regulations.
How do long-term capital gains differ from short-term capital gains?
Long-term capital gains apply when you hold a covered security or other capital asset for more than one year before the sale. These gains often receive different treatment because long-term entries can result in a lower capital gains tax rate. You must review each example carefully so the correct gain or loss appears on your tax return.
Does the wash sale rule apply if I buy the same security during the same period?
The wash sale rule applies when you sell and repurchase the same security within a limited time frame. The rule affects the gain or loss calculation because the adjustment prevents a claim that does not meet IRS regulations. You must review the dates carefully to confirm treatment for both covered and non-covered securities.
Do precious metals count as capital assets for tax reporting?
Precious metals qualify as capital assets when you sell items that produce a capital gain. These sales remain subject to capital gains tax rules, and each entry must appear on your tax return. Brokers may include a CUSIP number for clarity, although some items do not require one for proper reporting.
