Why is my actual paycheck different from this estimate?
This calculator estimates your full-year tax liability using the standard deduction and spreads it evenly across paychecks. Your employer withholds based on your Form W-4 entries, benefits, and any extra withholding you request, so individual paychecks can differ. Bonuses, overtime, multiple jobs, itemized deductions, and tax credits also change the final numbers.
