How Federal Income Tax Works
The United States uses a progressive tax system, meaning that as your income increases, the tax rate on the additional income also increases. Your income is divided into "brackets," and each bracket is taxed at a specific rate.
2025 Standard Deductions
The standard deduction reduces your taxable income. For the 2025 tax year (filed in 2026), the standard deductions are:
- Single: $14,600.00
- Married Filing Jointly: $29,200.00
- Head of Household: $21,900.00
