When you sell a stock for more than you paid for it you make a profit. The Internal Revenue Service refers to this profit as a capital gain, and wants its fair share in the form of capital gains taxes. As long as you've kept good records, you should be able to figure your capital gains tax without much trouble.
Your tax on a stock you sell is based on the difference between how much you paid for it and how much you sold it for, as well as whether you've held it for a year or more.
Capital Gains and Tax on Stock Sales
The capital gain on a stock is the amount you bought it for including commissions, called the basis, subtracted from the amount you sold it for, including commissions.
For most basic stock purchases, your basis is the price you paid for your stock plus any additional costs associated with making the purchase, such as brokerage fees, commissions, transfer fees or recording fees. If you acquired your stock at different times, you need to identify which shares you sold. This could make a difference between having a short-term or long-term capital gain.
Once you know your basis, determine your net proceeds from the stock sale. A positive capital gain on a stock results from the sale price of the stock, less any costs associated with making the sale, such as broker commissions and fees, being greater than zero. Subtract your net proceeds from your basis. If the result is a positive number, you have a capital gain. If the result is a negative number, you have a capital loss that you might be able to use to offset other gains.
Then, check your purchase and sale dates. If you owned the stock for one year or less, the IRS considers the resulting gain or loss to be short-term. Short-term capital gains on stock trades are taxed at the same rate as your ordinary income. If you owned the stock for more than one year before you sold it, the IRS considers the resulting gain or loss to be long-term. Long-term capital gains are typically taxed at a rate of 15 percent, though some very high income taxpayers pay 20 percent and some low income people pay zero. This is also the dividend tax rates for shareholder payments classified as qualified dividends.
Figure your gains or losses from all of your stock disposition transactions on IRS From 8949, then transfer the results to IRS Form 1040, Schedule D. Complete Schedule D to determine your tax liability for the sale.
Computing Basis for Stock You Didn't Buy
There are other methods of determining your basis if you acquired your stock though a method other than purchase, such as an inheritance or gift. The most common form is using the fair market value of the stock immediately prior to you taking possession of the stock, or when the person passed away in the case of inherited stock. The estate administrator or executor should be able to tell you the appropriate basis in the case of inherited stock.
2018 Tax Law Changes
The updates to the tax law in 2018 slightly change long term capital gains tax brackets, which are as of 2018 separate from tax brackets for ordinary income. There remain three capital gains rates, at 0, 15 percent and 20 percent.
Tax brackets on ordinary income, including short term capital gains, are generally lower, meaning these will often be taxed at a lower rate if stock is sold in 2018 rather than previous years.
The 2017 Tax Situation
In 2017, your long term capital gains tax rate depends on your ordinary income tax bracket, with your rate either 0, 15 percent or 20 percent.
Marginal tax rate brackets on ordinary income are generally higher than the brackets for the same amount of income in 2018 and subsequent years.
