Frequently Asked Questions

What is the difference between marginal and effective tax rate?

Your marginal rate is the tax bracket for your last dollar of income. Your effective rate is the actual percentage of total income paid in taxes — always lower than the marginal rate.

How do US federal tax brackets work?

The US uses a progressive system. Only income within each bracket is taxed at that rate. Earning more never reduces take-home pay from lower brackets.

What deductions can reduce my taxable income?

Common deductions include the standard deduction, mortgage interest, charitable donations, state taxes (SALT), and retirement contributions (401k, IRA).

Do I need to file a tax return?

Generally yes if your income exceeds the standard deduction ($16,100 single / $32,200 married in 2026), or if you had self-employment income over $400.

Does it work for self-employed income?

Yes for income tax, but self-employed people also owe self-employment / national-insurance taxes. Add roughly 15% (US self-employment tax) on top of the result for a complete estimate.
