Reporting Capital Gains and Losses to the IRS: Form 8949

The federal capital gains tax has been around in some form since 1916 and has occasionally been a hotbed of debate in some national elections. There have been very few big changes to the tax, but a few minor tweaks have occurred. These changes deal with reporting gains and losses, and they affect how much tax you'll pay to the federal government on gains.

A New Tax Form

The IRS rolled out a new tax form for reporting capital gains and losses from stocks, bonds, mutual funds, and similar investments during the 2011 tax year. Investment transactions are now reported on Form 8949, Sales and Other Dispositions of Capital Assets. The IRS also revised Schedule D and Form 1099-B to accommodate the new Form 8949.

The Emergency Economic Stabilization Act

Congress passed the Emergency Economic Stabilization Act in 2008. The EESA requires that brokers report the cost basis of investment products to investors and to the IRS on Form 1099-B.

In theory, having brokers report cost basis along with sales proceeds was intended to reduce the burden on individual taxpayers to maintain extensive records on their investments. It was thought that it would simplify the tax-reporting process.

Form 1099-B

Before the EESA, the 1099-B only reported information about the sale of investments, such as the date of sale and sale proceeds. Taxpayers then had to provide the purchase date and the purchase price when reporting the transactions on their tax returns.

Many brokers were already providing gain/loss reports as supplemental information with their annual reports and 1099-Bs, but cost basis information was included directly on the 1099-B beginning in 2011 if the broker was required to supply that information.

Brokers have been required to provide cost basis for stocks acquired beginning in 2011, and for mutual funds and stocks in a dividend reinvestment plan beginning in 2012. The reporting requirement began in 2013 for all other investment products acquired beginning in that year.

The IRS substantially revised Form 1099-B to facilitate this cost basis reporting, and Schedule D now functions as a summary of all capital gains transactions. Both of these forms are needed when filing a Form 8949.

Form 8949

Form 8949 is the reporting form used by individuals, businesses, and estates and trusts to report capital gains. The IRS provides the form and instructions for completing it.

Taxes on capital gains are based on the length of time the investment is held. Investments with realized capital gains occurring less than one year after purchase will have a higher tax rate than investments held for longer than one year.

Beginning in 2018, the TCJA has broad-ranging changes for taxpayers including some provisions for capital gains. Investors will continue to be taxed at ordinary income tax rates on short-term capital gains. Long-term capital gains are taxed in three buckets: 0 percent, 15 percent, and 20 percent.

Form 8949 provides for the reporting of both short term and long term capital gains. All types of taxpayers should receive the necessary tax reporting details for Form 8949 on a 1099-B statement.

Schedule D

Schedule D is most often used as a summation of the capital gains your report on Form 8949. In most cases, investors will use Schedule D to show the total capital gains from the year. Other situations that may also require a Schedule D include the following:

  • To report certain transactions you don't have to report on Form 8949.
  • To report a gain from Form 2439 or 6252 or Part I of Form 4797.
  • To report a gain or loss from Form 4684, 6781, or 8824.
  • To report a gain or loss from a partnership, S corporation, estate, or trust.
  • To report capital gain distributions not reported directly on Schedule 1 (Form 1040), line 13 (or effectively connected capital gain distributions not reported directly on Form 1040NR, line 14).
  • To report a capital loss carryover from 2017 to 2018.

The Tax Cuts and Jobs Act

Beginning in 2018, long-term capital gains have their very own tax brackets that will determine how much tax you will pay.

Long-term gains were taxed at either 0 percent, 15 percent, and 20 percent before the passage of the Tax Cuts and Jobs Act (TCJA), and that's still the case. But these rates used to be tied to your ordinary income tax bracket.

In other words, if your ordinary income put you in a 33 percent tax bracket on your overall income, you'd fall into the 15 percent long-term capital gains bracket. The 20 percent rate was reserved for those who fell into the top ordinary income tax bracket of 39.6 percent.

The TCJA gives long-term gains and qualified dividends their very own tax brackets effective January 1, 2018, but these still correlate with your overall income. Currently, the 0 percent capital gains rate applies to income up to $38,600 if you're single, $51,700 if you qualify as head of household, or $77,200 if you're married and file a joint return.

Beyond this, you'll jump into the 20 percent capital gains rate. This bracket covers incomes of up to $425,800 if you're single, $452,400 if you're head of household, or $479,000 if you're married and filing jointly. In other words, this bracket now covers a large swath of investors. You'll pay the 20 percent rate on your gains only if your overall income exceeds these levels.

The IRS is additionally issuing a whole new tax form for the 2018 tax year, a Form 1040 that will replace the old 1040, as well as Forms 1040A and 1040Ez. The new tax form is supposed to be shorter and simpler, but it comes with multiple schedules—along with all the old forms and schedules like Schedule D and Form 8949 that still exist.

Rest assured that you'll still be entering the same information, but in different places—as though preparing your taxes wasn't already complicated enough.

Keep Your Own Records

Cost-basis reporting by brokers will never fully and completely eliminate the need for taxpayers to maintain their own records because basis reporting applies only to newly acquired shares that have occurred since these changes were made. If you purchased stocks before 2011, mutual fund shares before 2012, or bonds before 2013, basis reporting on these assets won't be reported on Form 1099-B.

That information will likely be found in other reports or data, however, such as brokerage statements, year-end reports, or trade confirmations.
