How Salary Tax Works in the USA
The US tax system is progressive, meaning your income is taxed in portions at different rates (brackets). The process is:
- Start with your Gross Annual Salary.
- Subtract Pre-tax Deductions like 401(k) or HSA contributions. This lowers your income subject to tax.
- Apply the Standard Deduction for your filing status (or your itemized deductions if they are higher). This gives you your Taxable Income.
- Use the progressive tax brackets to calculate your Federal Income Tax on this taxable amount.
- Separately, calculate mandatory Payroll Taxes (Social Security & Medicare) on your gross income.
- The final result is your Net Take-Home Salary.

Frequently Asked Questions (FAQs)
Q1: What’s the difference between gross pay and net pay?
Gross pay is your total salary before any taxes or deductions are taken out. Net pay (or take-home pay) is the amount you actually receive in your paycheck after all federal, payroll, and state taxes have been withheld.
Q2: What is the standard deduction for 2025?
For tax year 2025, the standard deductions are: Single: $15,000; Married Filing Jointly: $30,000; Head of Household: $22,500; and Married Filing Separately: $15,000.
Q3: What's the marginal tax rate?
It’s the tax rate applied to your last dollar earned. For example, if your taxable income is $80,000 as a single filer, your highest tax bracket is 22%, making that your marginal rate. However, your overall (effective) rate is much lower because not all your income is taxed at that high rate.
Q4: Do I pay Social Security and Medicare on all my income?
Medicare (1.45%) applies to all your income. Social Security (6.2%) only applies up to an annual wage cap of $168,600 for 2025. Any income above that is not subject to Social Security tax.
Q5: How do pre-tax deductions lower my tax bill?
Contributions to accounts like a 401(k), traditional IRA, or Health Savings Account (HSA) are subtracted from your gross salary before tax is calculated. This reduces your taxable income, potentially placing you in a lower tax bracket and lowering your overall tax liability.
