What Are Federal Taxes?

At the simplest level, federal taxes are mandatory payments individuals and businesses make to the U.S. federal government. These taxes fund government programs, defense, infrastructure, social services, and more.

In 2025, the Internal Revenue Service (IRS) continues to be the main agency responsible for collecting federal taxes.

Key purposes of federal taxes include:

• Funding Social Security and Medicare programs.
• Paying for national defense and homeland security.
• Supporting public infrastructure (roads, airports, research).
• Financing federal education and healthcare initiatives.
• Paying down national debt.

👉 Simply put, without federal taxes, the government wouldn’t have the money to function.

Types of Federal Taxes in USA 2025

Federal taxes aren’t one-size-fits-all. They come in different categories depending on who pays them and why. Let’s break them down:

1. Federal Income Tax

• Paid by individuals and households on their earnings (salaries, wages, investments).
• Collected annually through tax returns.
• Progressive tax system → higher income = higher tax rate.
• Tax brackets in 2025 range from 10% to 37%.

Example:
If John earns $60,000 a year, he falls into the middle-income bracket and pays a mix of lower and higher rates (not just one flat rate).

2. Payroll Taxes (FICA Taxes)

• Shared by employees and employers.
• Fund Social Security (6.2%) and Medicare (1.45%).
• Self-employed individuals pay both halves (15.3%).

Example:
Sarah, a self-employed freelancer earning $50,000, pays around $7,650 in payroll taxes.

3. Corporate Taxes

• Paid by corporations on their profits.
• Federal corporate tax rate in 2025: 21%.
• Companies can deduct business expenses to reduce taxable income.

Example:
If a company earns $2 million in profit, it pays $420,000 in federal taxes.

4. Capital Gains Taxes

• Applied when you sell investments (stocks, real estate, cryptocurrency) for a profit.
• Two types: short-term (up to 37%) and long-term (0–20%) depending on how long you held the asset.

Example:
If Mike buys stock for $1,000 and sells it for $2,500 after 2 years, he pays long-term capital gains tax on the $1,500 profit.

5. Estate and Gift Taxes

• Applied to wealth transfers after death (estate tax) or large lifetime gifts.
• In 2025, estates valued over $13.61 million are taxed.

Example:
If someone leaves behind $20 million, only the amount above the exemption ($6.39 million) is taxable.
