Yes, corporations can claim business investment losses, but the rules depend on what type of investment lost money and how the corporation structured the purchase.
When a corporation buys stock, real estate, equipment, or other assets as part of its business operations and that asset loses value, the corporation may be able to deduct the loss on its tax return. The deduction reduces the corporation's taxable income for that year. However, not every loss qualifies, and the timing of when you can claim it matters.
The most common scenario is a capital loss — when a corporation sells an investment for less than it paid. A corporation can also claim a loss on assets that become worthless. The rules are different depending on whether the loss is short-term (held less than one year) or long-term (held one year or more), and they differ again if the investment was in a subsidiary or related business.
Key Takeaways
- Corporations can deduct capital losses when they sell an investment for less than they paid, but the deduction is limited to capital gains plus $3,000 per year for most corporations.
- Losses that exceed the annual limit can be carried back two years or forward indefinitely to offset gains in other years.
- A corporation must actually sell the asset or document that it became worthless — straightforward holding a declining investment does not create a deductible loss.
- Losses on investments in a subsidiary or related business may may have access to for a different deduction under Section 165(g) if the business becomes worthless.
- The corporation must report the loss on its tax return using Schedule D (for capital losses) or other forms depending on the asset type.
How Capital Losses Work for Corporations
A capital loss occurs when a corporation sells an investment — such as stock, bonds, or real estate held for investment — for less than its cost basis (what the corporation paid plus certain expenses). The loss is the difference between the sale price and the cost basis.
Corporations can use capital losses to offset capital gains. If a corporation sold one stock for a $50,000 gain and another for a $30,000 loss in the same year, the net capital gain is $20,000, and the corporation pays tax on that $20,000 instead of the full $50,000 gain.
If capital losses exceed capital gains in a year, most corporations can deduct up to $3,000 of the excess loss against ordinary income (such as revenue from selling products or services). Any loss beyond that $3,000 cannot be used in that year — it carries forward to future years indefinitely, where it can offset future gains or be deducted against ordinary income again, up to $3,000 per year.
When a Loss Becomes Deductible
A corporation cannot claim a loss straightforward because an investment is worth less than it paid. The loss must be realized — meaning the corporation either sold the asset or the asset became worthless.
If a corporation owns stock that dropped from $100 per share to $10 per share but has not sold it, there is no deductible loss yet. The moment the corporation sells those shares for $10 each, the loss is realized and can be claimed on the tax return.
An asset can also become worthless without a sale. If a corporation invested in a small business that shut down and the stock is now valueless, the corporation can claim a worthless stock loss in the year it became clear the business would not recover. The corporation must document when it determined the stock had no value — this is not automatic and requires evidence.
Short-Term Versus Long-Term Losses
The holding period affects how the loss is categorized but not whether it can be deducted. A short-term capital loss occurs when a corporation sells an asset it held for one year or less. A long-term capital loss occurs when the holding period was more than one year.
Both types of losses offset capital gains dollar-for-dollar. The distinction matters mainly for individual investors, where long-term gains and losses receive preferential tax rates. For corporations, the tax rate on capital gains is the same as the rate on ordinary income, so the holding period does not change the tax benefit of the loss itself — only how it is reported on the tax return.
A corporation must report short-term and long-term losses separately on Schedule D, but both reduce taxable income in the same way.
Losses on Investments in Related Businesses
If a corporation invested in a subsidiary, partnership, or other related business and that investment became worthless, the loss may may have access to under Section 165(g) of the tax code. This rule allows a deduction for a worthless security in a subsidiary if the parent corporation owned more than 80 percent of the subsidiary's stock.
A Section 165(g) loss is treated as a long-term capital loss regardless of how long the corporation held the stock. This can be advantageous because it allows the loss to be carried back to offset gains in prior years, whereas ordinary capital losses can only be carried forward.
The corporation must prove the security became worthless during the tax year and must identify the specific year in which worthlessness occurred. This is often the year the subsidiary ceased operations, filed for bankruptcy, or was formally dissolved.
Carrying Losses Back and Forward
When a corporation has a capital loss that exceeds what it can deduct in the current year, the excess can be used in other years. The rules for carrying losses depend on the type of loss and when it occurred.
Most capital losses can be carried forward indefinitely. A corporation with a $50,000 capital loss in 2024 that can only deduct $3,000 against ordinary income that year can carry the remaining $47,000 forward to 2025, 2026, and beyond, using it to offset future gains or deduct up to $3,000 per year against ordinary income.
Some losses, particularly those from Section 165(g) worthless securities, can be carried back two years. This means a corporation can amend its tax return for the prior two years to claim the loss and receive a refund of taxes already paid. Carrying back is optional — a corporation can choose to carry forward instead if that is more beneficial.
How to Report the Loss on the Tax Return
A corporation reports capital losses on Schedule D (Form 1120), which is part of the corporate tax return. The schedule lists each sale or worthless asset separately, showing the date acquired, date sold, cost basis, sale price, and the gain or loss.
The corporation calculates net short-term and net long-term losses, then combines them to determine the total capital loss for the year. This total is then used to offset capital gains and, if applicable, up to $3,000 of ordinary income.
If the corporation is carrying back a loss to a prior year, it must file an amended return (Form 1120-X) for that year. If it is carrying forward a loss, the corporation notes the carryforward amount and uses it on the current year's return.
Frequently Asked Questions
Can a corporation claim a loss on an investment it still owns?
No. A loss must be realized through a sale or by documenting that the asset became worthless. straightforward holding an investment that has declined in value does not create a deductible loss. The corporation must either sell the asset or prove it has no value.
What if the corporation's capital losses are larger than its capital gains?
The corporation can deduct up to $3,000 of the excess loss against ordinary income in that year. Any loss beyond $3,000 carries forward to future years, where the same $3,000 limit applies each year until the loss is fully used.
Can a corporation claim a loss on a bad loan it made to another business?
Yes, if the loan became worthless. A corporation can claim a bad debt deduction under Section 166 if it loaned money to another business and that business failed to repay. The corporation must show the debt is uncollectible and identify the year it became clear repayment would not happen.
Does the holding period change how much loss a corporation can deduct?
No. Both short-term and long-term capital losses offset capital gains dollar-for-dollar and are subject to the same $3,000 annual limit against ordinary income. The holding period affects how the loss is reported but not the amount of the deduction.
Can a corporation carry a capital loss back to a prior year?
Most capital losses can only be carried forward. However, losses on worthless securities in a subsidiary (Section 165(g) losses) can be carried back two years, allowing the corporation to amend prior returns and recover taxes already paid.
