FAQ

What is the difference between Marginal and Effective Tax Rate?
Your marginal tax rate is the tax percentage applied to your highest dollar of taxable income. Your effective tax rate is the total tax paid divided by your overall gross taxable income.
How does FICA tax withholding work in the United States?
FICA consists of Social Security (6.2% up to the annual wage cap) and Medicare (1.45% on all earnings, plus 0.9% additional Medicare tax for high earners).
Can tax calculators replace official IRS tax filings?
No. Online tax tools provide estimates based on standard statutory rates. Final tax liability depends on exact Form 1040 deductions, state credits, and professional advice from a CPA or Enrolled Agent.
