Frequently asked questions

What is the difference between marginal and effective tax rate?

Your marginal tax rate is the rate applied to your last dollar of income — the highest bracket you fall into. Your effective tax rate is your total tax divided by your total income, representing the average rate you actually pay across all brackets. For example, a single filer earning $100,000 in 2025 has a 22% marginal rate but an effective federal income tax rate of about 14.5%.

What taxes are included in total tax burden?

This calculator includes federal income tax, state income tax, and employee FICA taxes (Social Security at 6.2% up to the wage base of $176,100 for 2025, Medicare at 1.45%, and Additional Medicare at 0.9% on income over $200,000 for single filers). It uses the standard deduction and does not include sales tax, property tax, or self-employment tax.

Why does the effective rate curve flatten at higher incomes?

The effective rate curve grows most steeply at lower incomes as you move through brackets. At very high incomes, most additional dollars are taxed at the top marginal rate (37% federal), so the effective rate converges toward but never reaches the marginal rate. FICA's Social Security component also caps at the wage base ($176,100 for 2025), which actually lowers the FICA effective rate at higher incomes.

How does filing status affect my tax burden?

Married Filing Jointly has the widest tax brackets (roughly double the single brackets) and the highest standard deduction ($31,500 for 2025). Head of Household has wider brackets and a higher standard deduction ($23,625) than Single ($15,750). Married Filing Separately has the narrowest brackets and loses access to many credits. At the same income, MFJ typically produces the lowest effective rate.

What are the key tax thresholds to watch?

Key thresholds include: the standard deduction (below this, you owe no federal income tax), each federal bracket boundary (where your marginal rate jumps), the Social Security wage base ($176,100 for 2025, above which SS tax stops), and the Additional Medicare threshold ($200,000 single / $250,000 MFJ, above which an extra 0.9% applies).
