Deep Dive How is Capital Gains Tax Calculated for U.S. Companies? How Much Do You Know?

In recent years, with the changes in the global economic landscape and adjustments to tax policies, the United States, as one of the largest economies in the world, has seen growing attention focused on the details of its tax system. Among these, capital gains tax, an important financial burden for corporate operations, not only affects profit distribution but also indirectly determines the direction of investment decisions. So, how do U.S. companies calculate capital gains tax? The answer to this question may be more complex than many imagine.

What is Capital Gains Tax?

Capital gains tax refers to the tax payable on the profits obtained from selling assets such as stocks or real estate by individuals or businesses. For U.S. companies, when they sell long-held assets and generate a positive difference i.e., the selling price exceeds the purchase price, this difference is considered capital gains and must be taxed at the corresponding rate.

For example, in 2025, according to the rules set by the Internal Revenue Service IRS, capital gains are divided into short-term and long-term categories. Short-term capital gains refer to the proceeds from selling assets held for less than a year; long-term capital gains correspond to situations where the holding period exceeds one year. Short-term capital gains are typically classified as ordinary income and subject to standard corporate income tax rates, while long-term capital gains enjoy lower rates, which depend on the taxpayer's total income level.

How is Capital Gains Tax Calculated?

After understanding the basic concept of capital gains tax, let us look at the specific calculation process. Assume that an American company has just sold an asset valued at $1 million, originally purchased for $600,000, held for two years. In this case

1. Determine the Amount of Capital Gains

First, the specific amount of capital gains must be clarified. The formula is

Capital Gains = Selling Price Purchase Price

In the above example, the capital gains would be $1,000,000 $600,000 = $400,000.

2. Distinguish Between Short-Term and Long-Term Capital Gains

Since the holding period for this asset exceeded two years, this income falls under long-term capital gains. According to current tax law, the long-term capital gains tax rate is divided into three tiers

For households with annual income below $89,850, the tax rate is 0%;

For households with annual income between $89,850 and $457,600, the tax rate is 15%;

For households with annual income exceeding $457,600, the tax rate is 20%.

Assuming this company has a high annual income, it will apply the 20% tax rate.

3. Final Tax Liability Calculation

Multiply the capital gains amount by the applicable tax rate to determine the tax payable

Tax Payable = Capital Gains × Tax Rate

In this case, the tax payable would be $400,000 × 20% = $80,000.

The Actual Impact of Capital Gains Tax on Enterprises

At first glance, capital gains tax appears to be a simple mathematical calculation. However, in reality, this tax type has far-reaching effects on enterprises. First, the existence of capital gains tax directly impacts enterprise cash flow management. For instance, during economic downturns, many companies may choose to delay asset sales to avoid heavy tax burdens, thereby increasing liquidity pressure.

Secondly, changes in the capital gains tax rate are often closely linked to macroeconomic policies. For example, in recent years, the U.S. has proposed several times to increase the capital gains tax rate for high-income groups, which has drawn significant attention from business circles. Although these proposals have yet to be fully implemented, it can be foreseen that the capital gains tax rate may further differentiate in the future, thus exacerbating the financial disparities among enterprises of different sizes.

Latest Developments The Prospects for Capital Gains Tax Reform

It is worth noting that the U.S. Congress is currently discussing a new tax bill aimed at promoting economic growth by optimizing the capital gains tax mechanism. According to media reports, this bill may include the following points

Raising the upper limit of the capital gains tax rate for high-net-worth individuals;

Strengthening regulation of cryptocurrency transactions and incorporating them into the scope of capital gains tax collection;

Introducing new measures to reduce taxes for small and medium-sized enterprises to alleviate their operational cost pressures.

Although these proposals are still in their preliminary stages, they undoubtedly reflect the strong call for reform of the capital gains tax system in society today. For investors, closely monitoring these policy trends is crucial.

Summary

In summary, the calculation method for U.S. corporate capital gains tax appears straightforward but involves multiple considerations. Whether from a corporate strategic perspective or a tax planning standpoint, a deep understanding of this system holds significant importance. With the continuous evolution of the global economic environment, the rules governing capital gains tax may also adjust accordingly. Both enterprises and individuals need to maintain keen insight and adapt promptly to changes to ensure the maximization of their own interests.
