Income Tax Estimator
A simplified peek at your tax bill — not tax advice.
This estimator applies a simple illustrative 3-bracket tax scheme to your income so you can see roughly how progressive taxation works. It is deliberately simplified — real tax codes have deductions, credits and many more brackets. For actual filing, use official tools or a tax professional.
How it's calculated
Simplified illustrative brackets — Single: 0% up to $10k, 15% on $10k–$50k, 25% above $50k; Married: 0% up to $20k, 15% on $20k–$100k, 25% above $100k. This is a teaching model, not real tax law, and not tax advice.
Frequently asked questions
Is this my real tax bill?
No. This is a simplified estimate using an illustrative 3-bracket scheme, not any country's actual tax code. Real taxes involve deductions, credits, payroll taxes and many brackets — this tool just demonstrates how progressive brackets work.
What's the difference between marginal and effective rate?
Your marginal rate is the tax on your last dollar earned (here, 15% or 25%); your effective rate is total tax divided by total income, and it's always lower. Confusing the two is the most common tax myth.
Why do married brackets differ?
Many tax systems give married couples wider brackets to reduce the 'marriage penalty.' In this simplified model, married thresholds are simply doubled — real codes are more nuanced.
