Frequently asked questions

How do tax brackets work?

Brackets are marginal: only the income within each bracket’s range is taxed at that rate. Moving into a higher bracket never reduces your take-home pay.

What is FICA?

A mandatory payroll tax: 6.2% Social Security on wages up to the annual cap plus 1.45% Medicare on all wages, matched by your employer.

Does this include state tax?

No — it models US federal income tax with the standard deduction plus FICA. State and local taxes vary widely and are excluded.
