How is federal income tax calculated in 2025?
Federal income tax uses a progressive bracket system with seven rates ranging from 10% to 37%. Your taxable income is your gross income minus the standard deduction ($15,000 for single filers, $30,000 for married filing jointly in 2025). Each portion of your income is taxed at the rate for its bracket, so moving into a higher bracket only affects the income above that threshold.
What is FICA and how much is it?
FICA stands for Federal Insurance Contributions Act and funds Social Security and Medicare. In 2025, employees pay 6.2% for Social Security on earnings up to $176,100 and 1.45% for Medicare on all earnings. An additional 0.9% Medicare surtax applies to earnings above $200,000 for single filers ($250,000 for married filing jointly).
How does state income tax affect my paycheck?
State income tax varies significantly across the US. Nine states (Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming) have no state income tax. Other states use either a flat rate (like Illinois at 4.95%) or progressive brackets (like California, which ranges from 1% to 13.3%). State tax is applied on top of federal tax.
What is the standard deduction for 2025?
For the 2025 tax year, the standard deduction is $15,000 for single filers and married filing separately, $30,000 for married filing jointly, and $22,500 for head of household. Additional deductions of $1,600 (single) or $1,300 (married) are available for taxpayers who are blind or age 65 and older.
