Yes. Corporations do pay capital gains tax, but how depends on the entity type. A C-corporation pays federal tax on capital gains at the flat 21% corporate rate, the same rate that applies to all its other taxable income, with no reduced rate for long-term holdings. S-corporations, partnerships, and most LLCs generally pay nothing at the entity level; the gain passes through to the owners, who report it on their personal returns at individual capital gains rates.
The 21% Rate Applies to Every C-Corporation Capital Gain
When a C-corporation sells an asset for more than its adjusted basis, the profit becomes part of the corporation’s taxable income and is taxed at 21%. The Tax Cuts and Jobs Act of 2017 replaced the old graduated corporate rate structure, which topped out at 35%, with the single flat rate, and subsequent 2025 legislation made it permanent.1U.S. Government Accountability Office. Corporate Income Tax: Effective Rates Before and After 2017 Law Change
The holding period does not change the rate. Whether a C-corporation held an investment for six months or six years, the gain is taxed at 21%. Individual taxpayers can pay as little as 0% on long-term gains depending on income bracket; corporations get no such preference. Form 1120 confirms the arithmetic: multiply taxable income by 21%.2Internal Revenue Service. Instructions for Form 1120 (2025)
Double Taxation on Distributed Gains
The 21% is only the first layer. When the corporation distributes those after-tax profits as dividends, shareholders owe tax again on their personal returns. As the IRS puts it: “The profit of a corporation is taxed to the corporation when earned, and then is taxed to the shareholders when distributed as dividends. This creates a double tax.”3Internal Revenue Service. Forming a Corporation
A shareholder in the top bracket can pay up to 23.8% on qualified dividends (a 20% capital gains rate plus the 3.8% net investment income tax). Combined with 21% at the entity level, the total federal burden on a dollar of corporate capital gain that gets distributed can exceed 40%. That math is why closely held businesses often choose a pass-through structure instead.
Pass-Through Entities Don’t Pay at the Entity Level
S-corporations, partnerships, and most LLCs are pass-through entities. They file information returns but owe no federal income tax on capital gains. Each owner receives a Schedule K-1 reporting their share, and the gain lands on the owner’s personal return.4Internal Revenue Service. Partner’s Instructions for Schedule K-1 (Form 1065) (2025)5Internal Revenue Service. About Form 1065, U.S. Return of Partnership Income
For those individual owners, the holding period does matter. Long-term gains on assets held more than one year are taxed at 0%, 15%, or 20% depending on the owner’s taxable income, versus ordinary rates that can reach 37%. That preferential treatment is unavailable to a C-corporation on the same sale.
The Built-In Gains Exception After an S-Election
There is one significant exception. When a C-corporation converts to S-corporation status, the entity itself owes tax under Section 1374 on gains from selling assets that appreciated while it was still a C-corporation. This built-in gains tax applies during a five-year recognition period beginning with the first tax year as an S-corporation.6Office of the Law Revision Counsel. 26 USC 1374 – Tax Imposed on Certain Built-in Gains
The rate equals the highest corporate rate under Section 11(b), currently 21%, and applies to the lesser of the recognized built-in gain or the S-corporation’s taxable income for the year. A company that converted in January 2023 would be exposed on sales of pre-conversion appreciated assets through the end of 2027. After the window closes, all gains pass through normally. The rule does not apply to corporations that have been S-corporations for every year of their existence.6Office of the Law Revision Counsel. 26 USC 1374 – Tax Imposed on Certain Built-in Gains
Capital Losses Are Walled Off From Ordinary Income
Corporations must net capital gains against capital losses for the year before calculating tax. This is where corporate treatment departs sharply from individual treatment. An individual with excess capital losses can deduct up to $3,000 against ordinary income like wages. Corporations cannot. Capital losses are deductible only against capital gains, and any excess is entirely walled off from reducing other business income.7Office of the Law Revision Counsel. 26 USC 1211 – Limitation on Capital Losses
If a corporation ends the year with a net capital loss, Section 1212 provides two paths. The loss can be carried back to the three preceding tax years and applied against capital gains reported in those years, potentially generating a refund; the carryback cannot create or increase a net operating loss. Any remaining unused loss carries forward as a short-term capital loss for up to five years.8Office of the Law Revision Counsel. 26 USC 1212 – Capital Loss Carrybacks and Carryovers
Five years is a hard deadline. Any loss not absorbed within that window is gone permanently. A company with a bad investment year in 2022 that doesn’t generate enough capital gains by 2027 will lose whatever remains of the deduction.8Office of the Law Revision Counsel. 26 USC 1212 – Capital Loss Carrybacks and Carryovers
Which Assets Produce Capital Gains
Capital assets for a corporation include stocks, bonds, other portfolio investments, and land not used in the business. Gain equals sale price minus adjusted basis. Adjusted basis starts with the purchase price and moves with events during ownership: depreciation deductions reduce it because those deductions already recovered part of the cost, and improvements increase it.9Legal Information Institute. Adjusted Basis
Property used in the trade or business, such as equipment, machinery, and buildings, sits in a separate category called Section 1231 property. Section 1231 offers asymmetric treatment: net gains are taxed as long-term capital gains, while net losses are treated as ordinary losses that offset any type of income.10Office of the Law Revision Counsel. 26 USC 1231 – Property Used in the Trade or Business and Involuntary Conversions The recapture and lookback rules below claw back much of that benefit.
Depreciation Recapture Reclassifies Some Gain as Ordinary Income
When a corporation sells depreciable property at a gain, some or all of that gain is reclassified as ordinary income rather than capital gain. The purpose is to prevent a business from deducting depreciation against ordinary income for years and then treating the resulting profit as favorably taxed capital gain.
Section 1245: Personal Property
Section 1245 covers tangible personal property like machinery, equipment, vehicles, and furniture. Gain up to the total depreciation previously claimed is treated as ordinary income. Only gain exceeding original cost qualifies as capital gain, and because equipment rarely sells above its original purchase price, the entire gain is usually recharacterized as ordinary.11Office of the Law Revision Counsel. 26 USC 1245 – Gain From Dispositions of Certain Depreciable Property
Section 1250 and the Section 291 Corporate Penalty
Section 1250 covers depreciable real property such as commercial buildings and warehouses. Recapture here is narrower: only depreciation in excess of straight-line is recaptured as ordinary income.12Office of the Law Revision Counsel. 26 USC 1250 – Gain From Dispositions of Certain Depreciable Realty Because most modern real property uses straight-line depreciation, Section 1250 recapture is often zero for individual taxpayers.
Corporations face an extra layer. Section 291 requires a corporation to treat 20% of the difference between what Section 1245 would have recaptured and what Section 1250 actually recaptured as ordinary income. The effect is to convert a larger share of the gain to ordinary income on a corporate sale of real property than an individual would face on the same building.13Office of the Law Revision Counsel. 26 USC 291 – Special Rules Relating to Corporate Preference Items It is one of the concrete places where C-corporation treatment is worse than the treatment individuals receive on the identical transaction.
The Section 1231 Five-Year Lookback
The favorable capital gain treatment on Section 1231 property has a catch. If the corporation claimed an ordinary loss on Section 1231 property in any of the five preceding tax years, current-year Section 1231 gains are recharacterized as ordinary income to the extent of those prior unrecaptured losses.10Office of the Law Revision Counsel. 26 USC 1231 – Property Used in the Trade or Business and Involuntary Conversions
Say a corporation took a $200,000 ordinary loss on equipment in 2023, then sells a building in 2026 for a $500,000 Section 1231 gain. The first $200,000 is treated as ordinary income. Only the remaining $300,000 gets capital gain treatment. You cannot claim ordinary loss treatment on the way down and capital gain treatment on the way up without first squaring the prior losses.
State Corporate Tax Adds Another Layer
The 21% federal rate isn’t the whole bill. Most states tax corporate capital gains as ordinary business income at the state’s standard corporate rate. Those rates range from 0% in states without a corporate income tax to more than 11% in the highest-taxed jurisdictions, with a typical top rate around 6% to 7%. A handful of states impose gross receipts taxes instead, which can reach capital transactions differently.
A C-corporation in a state with a 7% corporate rate faces roughly 28% in combined federal and state tax on an appreciated-asset sale before any shareholder-level tax on distributions. State rules on loss carrybacks and carryovers also vary, and some states do not permit carrybacks at all. Confirm the specific state rules before planning a large sale.
Reporting and Estimated Tax
C-corporations report capital gains and losses on Schedule D (Form 1120). Individual transactions run through Form 8949 first and then summarize on Schedule D. Gains from selling business property go on Form 4797, with the result carried to Form 1120.14Internal Revenue Service. 2025 Instructions for Schedule D (Form 1120) Calendar-year Form 1120 is due April 15; Form 7004 grants a six-month extension to file but not to pay.2Internal Revenue Service. Instructions for Form 1120 (2025)
A C-corporation expecting to owe $500 or more must make quarterly estimated payments due April 15, June 15, September 15, and December 15, each generally equal to 25% of the required annual payment.15Office of the Law Revision Counsel. 26 USC 6655 – Failure by Corporation to Pay Estimated Income Tax A large mid-year capital gain can create an underpayment problem if earlier installments were based on a lower income projection. The annualized income installment method allows the corporation to size each quarter’s payment to income actually earned through that point, concentrating a larger payment in the quarter the gain lands.
Owners of pass-through entities face the same issue at the individual level. A large K-1 capital gain often requires increased estimated payments or additional withholding to avoid underpayment penalties, which apply when you expect to owe at least $1,000 after withholding and credits and your withholding covers less than 90% of current-year tax (or 100% of last year’s, rising to 110% if adjusted gross income exceeded $150,000).16Internal Revenue Service.
