3.4 Overall Netting of Capital Gain (Loss)

Learning Objectives

  • Apply Section 1231 gain/loss netting rules.
  • Net capital gains/losses across all property transactions, considering holding periods.
  • Identify the main tax forms for reporting capital gains and losses.

Understanding how to net capital gains and losses is crucial for accurately calculating your individual income tax liability arising from property transactions. This chapter will delve into the specific rules governing the netting process, including the unique treatment of gains and losses from certain business property under Section 1231 of the Internal Revenue Code (IRC), the overall netting of capital gains and losses across all property transactions, and the tax forms required to report these amounts.

Section 1231 Gain (Loss) Netting: Special Rules for Business Property

Defining Section 1231 Property:

IRC Section 1231 applies to gains and losses from the sale or exchange of certain types of property used in a trade or business and held for more than one year. Common examples of Section 1231 property include:

  • Depreciable property used in a trade or business (e.g., machinery, equipment, buildings).  
  • Real property used in a trade or business (e.g., land, warehouses). 
  • Timber, coal, or domestic iron ore.
  • Livestock held for specific purposes and durations.
  • Unharvested crops sold with the land.

Initial Netting of Section 1231 Gains and Losses:

The tax treatment of gains and losses from the disposition of Section 1231 property involves a two-step netting process. First, you must net all gains and losses from the sale, exchange, or involuntary conversion of Section 1231 property.
  • If the net result is a gain: This net gain is treated as a long-term capital gain. This is a significant benefit as long-term capital gains are typically taxed at lower rates than ordinary income. 
  • If the net result is a loss: This net loss is treated as an ordinary loss. Ordinary losses are fully deductible against ordinary income, which can be more advantageous than capital losses, which have limitations on their deductibility.  

The Section 1231 “Look-Back” Rule:

There’s an important exception to the rule that net Section 1231 gains are treated as long-term capital gains. The “look-back” rule, found in IRC Section 1231(c), requires that a portion of the current year’s net Section 1231 gain be treated as ordinary income to the extent of any unrecaptured net Section 1231 losses from the five preceding tax years. This rule prevents taxpayers from recognizing ordinary losses in one year and then offsetting those losses with capital gains in a later year.

Example of Section 1231 Netting

Imagine a business owner sells a piece of machinery (Section 1231 property) for a $10,000 gain and also sells a business truck (another Section 1231 property) for a $3,000 loss in the same year. The net Section 1231 gain is $7,000 ($10,000 – $3,000). Assuming the look-back rule doesn’t apply, this $7,000 will be treated as a long-term capital gain.

Now, consider another scenario where the business owner sells the machinery for a $2,000 gain and the truck for a $5,000 loss. The net Section 1231 loss is $3,000 ($2,000 – $5,000). This $3,000 will be treated as an ordinary loss, fully deductible against the business owner’s ordinary income.

  • Capital Gain (Loss) Netting Across All Property Transactions
  • After the initial netting of Section 1231 gains and losses, the resulting net Section 1231 gain (if any) is then included in the overall capital gain and loss netting process. This process involves combining capital gains and losses from all types of property transactions, including those involving Section 1231 property (that resulted in a net gain).

The Overall Netting Process:

  1. Net Short-Term: Combine all short-term capital gains and short-term capital losses. This results in either a net short-term capital gain or a net short-term capital loss.
  2. Net Long-Term: Combine all long-term capital gains (including any net Section 1231 gain treated as long-term) and long-term capital losses. This results in either a net long-term capital gain or a net long-term capital loss.
  3. Offsetting Net Amounts:
    • If you have a net short-term capital gain and a net long-term capital loss, you offset the long-term loss against the short-term gain.
    • If you have a net long-term capital gain and a net short-term capital loss, you offset the short-term loss against the long-term gain.

Tax Forms to Report the Final Gain or Loss

  • Form 4797, Sales of Business Property: This form is used to report the sale or exchange of Section 1231 property, as well as other business property. The initial netting of Section 1231 gains and losses is performed on this form. The net Section 1231 gain (or loss) is then transferred to Schedule D or reported as ordinary income (in the case of a net loss).
  • Form 8949, Sales and Other Dispositions of Capital Assets: This form is used to list the details of each sale or other disposition of capital assets (both short-term and long-term). This includes stocks, bonds, investment real estate, and other capital assets. Information from this form is then summarized on Schedule D. 
  • Schedule D (Form 1040), Capital Gains and Losses: This is the primary form used to summarize your overall capital gains and losses. It takes the information from Form 8949 (and the net Section 1231 gain from Form 4797) to perform the final netting calculations. Schedule D ultimately determines your net capital gain or loss, which is then reported on Form 1040, U.S. Individual Income Tax Return.

Taxation of Net Capital Gains:

 Individuals can deduct up to $3,000 of this net capital loss against their ordinary income each year (IRC Section 1211(b)). Any unused capital loss can be carried forward indefinitely to future tax years to offset future capital gains and, if necessary, up to $3,000 of ordinary income annually. Net Short-Term Capital Gain is taxed as ordinary income.

To understand how net long-term capital gain is calculated, it’s important to recognize that the category of “long-term capital gain” encompasses various types of gains, some of which may be subject to different maximum tax rates. A long-term capital gain arises from the sale or exchange of a capital asset held for more than one year (IRC Section 1222(3)). 

Here’s a breakdown of the common types of long-term capital gains and how they contribute to the net long-term capital gain calculation:
  • General Long-Term Capital Gains: This is the most common type, resulting from the sale of assets like stocks, bonds, investment real estate (other than depreciable real property), mutual funds, and other typical capital assets held for longer than a year. These gains are generally taxed at the preferential long-term capital gains rates of 0%, 15%, or 20%, depending on the taxpayer’s taxable income and filing status (IRC Section 1(h)). 
  • Collectibles Gain: Gains from the sale of collectibles, such as art, antiques, stamps, and coins, held for more than one year are considered long-term capital gains but are subject to a maximum tax rate of 28% (IRC Section 1(h)(1)). This higher rate reflects the nature of these assets as often being for personal enjoyment as well as investment.
  • Unrecaptured Section 1250 Gain: This specifically relates to the sale of depreciable real property (often referred to as Section 1250 property) used in a trade or business. When such property is sold at a gain, a portion of the gain may represent the depreciation deductions that were previously taken. This “unrecaptured Section 1250 gain” is taxed at a maximum rate of 25% (IRC Section 1(h)(1)(D)).It’s important to note that the gain exceeding the accumulated depreciation is generally taxed at the regular long-term capital gains rates.
  • Small Business Stock Gain (Section 1202): Under IRC Section 1202, certain taxpayers may be able to exclude a portion of the gain from the sale of qualified small business stock held for more than five years. The excludable amount can be up to the greater of $10 million or 10 times the taxpayer’s basis in the stock. The portion of the gain that is not excluded is taxed at the regular long-term capital gains rates, but with a maximum rate of 28% on the non-excluded portion.
  • Qualified Dividends: While not directly a gain from the sale of an asset, qualified dividends received from certain stocks are taxed at the same long-term capital gains rates (IRC Section 1(h)(11)). This treatment aligns the taxation of certain corporate profits distributed to shareholders with the taxation of gains from selling those shares held long-term.
 Net long-term capital gains, while often taxed at lower rates, are effectively layered on top of your ordinary income to determine the applicable capital gains tax rate. Ordinary income fills up the lower tax brackets first. Ordinary income tax liability is calculated, any net long-term capital gain is then considered. The tax rate applied to this capital gain depends on your total taxable income, including both your ordinary income and the capital gain itself.  (including capital gain tax calculator here)

Key Takeaways

The taxation of net long-term capital gains is intertwined with your ordinary income. While long-term capital gains generally enjoy lower tax rates, the specific rate you pay depends on your overall taxable income, which includes all sources of income. Furthermore, certain types of long-term capital gains have their own specific maximum tax rates that might apply. Therefore,

when planning for property transactions, it’s crucial to consider your total income picture to understand the potential tax implications of any capital gains realized.
