How your take-home pay is calculated
Federal income tax for 2026 uses seven brackets from 10% to 37%. It is applied after the standard deduction of $16,100 for single filers, $32,200 for married couples filing jointly and $24,150 for heads of household.
FICA comes next: 6.2% Social Security on wages up to $184,500 and 1.45% Medicare on all wages, plus 0.9% Medicare on wages above $200,000 ($250,000 for joint filers). Then your state’s income tax and any state payroll programs, such as California SDI or New York paid family leave, are subtracted.
