Capital gains are the profits you make from selling an investment, like stocks or bonds, for more than you paid for it. This profit is considered taxable income.
To calculate capital gains, you subtract the original purchase price from the sale price. For example, if you bought 100 shares of stock for $10 each and sold them for $15 each, your capital gain would be $500.
This calculation is straightforward, but it's essential to understand the tax implications of capital gains. Fidelity, as a brokerage firm, can help you navigate these complexities.
The tax rate on capital gains depends on your income level and the type of investment. For instance, if you're a long-term investor, you might qualify for a lower tax rate on your capital gains.
Capital Gains Basics
Taxpayers have a responsibility to report gains and losses, and related cost basis information when they file their income tax returns. This includes filing Schedule D with your Form 1040.
You must also file Form 8949, which provides a format for listing each individual sales transaction that you make during the year. This helps ensure you're accurately reporting your capital gains.
Brokers, such as Fidelity, have a requirement to report sales information to the IRS on Form 1099-B. This form helps the IRS track your investment activity.
Mutual funds pay capital gains distributions from their net realized long-term capital gains. These distributions are taxed as long-term capital gains regardless of how long you've owned the shares.
You must report your share of unpaid distributions as long-term capital gains, even if you didn't receive a distribution. This is because you're considered to have paid the tax, and you can claim a credit for your share of any tax paid.

Reporting Requirements
Reporting requirements for Fidelity capital gains can be a bit complex, but don't worry, I'm here to break it down for you.
You'll need to file Schedule D with your Form 1040 to report capital gains on your return. Most filers will also need to start with Form 8949, which provides a format for listing each individual sales transaction.

Fidelity has a reporting feature that allows you to calculate investors' capital gains positions for investments held on the platform. This feature includes unrealised and tax-year specific realised gains reports, which can be accessed on screen or downloaded as a PDF or Excel spreadsheet.
The consolidated capital gains report combines both reports into one document, and you can deliver bulk and/or single client reports. Reports account for historic deals with daily updates of new transactions, and calculations are made using prices from the end of the previous business day.
Here's a summary of the reporting features:
- Unrealised and tax-year specific realised gains reports
- Excess Reportable Income (ERI) calculation
- Entry of acquisition costs for capital gains purposes
- Consolidated capital gains report
- Bulk and/or single client reports
- Historic deal accounting with daily updates
- Calculations using end-of-day prices
Note that Fidelity also has a requirement to report sales information to the IRS on Form 1099-B. So, be sure to keep track of your sales transactions and report them accordingly.
Funds
Mutual funds pay capital gains distributions from their net realized long-term capital gains, which are taxed as long-term capital gains.
You must report your share of unpaid distributions as long-term capital gains, even if you didn't receive a distribution.
Mutual funds can keep some of their long-term capital gains and pay taxes on those undistributed amounts.
You can claim a credit for your share of any tax paid on unpaid distributions, as you're considered to have paid it.

Disposal Methods
Disposal Methods can significantly impact the amount of taxes you owe on your investments. Fidelity offers several methods to choose from, each with its own effects on your taxable gains.
First In, First Out (FIFO) is the default method for most securities, but it may result in larger taxable gains than other disposal methods. This is because shares with the oldest acquisition date are sold first, regardless of cost basis.
Intraday First In, First Out is another option, which may reduce short-term taxable gains and increase long-term taxable gains. This method sells shares purchased today first, and then reverts to FIFO once all lots purchased today have been sold.
Using Last In, First Out (LIFO) or High-Cost can help reduce taxable gains. LIFO sells shares with the most recent acquisition date first, while High-Cost sells shares with the greatest cost basis first.
High-Cost Long-Term and High-Cost Short-Term methods also exist, which prioritize shares with a long-term or short-term holding period, respectively. These methods can also help reduce taxable gains.
A fresh viewpoint: Basis Point

Tax-Sensitive and Tax-Sensitive Short-Term methods use a tax liability calculation to determine which shares to sell first. They may help reduce taxable gains, especially for shares with losses.
Lastly, Specific Share Identification allows you to choose which specific lots you sell at a given time, giving you the most control over your taxable gains. However, this method is the most labor-intensive.
Here's a summary of the disposal methods:
