Máy tính thuế là gì?

A tax calculator helps you estimate your income tax liability based on your earnings, deductions, and applicable tax brackets. Understanding how much tax you owe is essential for financial planning, budgeting, and avoiding surprises during tax season. This calculator provides a clear breakdown of your tax obligations across different income brackets.

Most countries use a progressive tax system, where different portions of your income are taxed at different rates. This means not all your income is taxed at the same rate. Understanding how tax brackets work helps you make informed decisions about deductions, contributions, and financial planning strategies to optimize your tax situation.

Câu Hỏi Thường Gặp

What is a tax bracket?

A tax bracket is a range of income taxed at a specific rate. In a progressive system, only the income within each bracket is taxed at that bracket's rate, not your entire income.

What's the difference between marginal and effective tax rate?

Your marginal tax rate is the rate applied to your last dollar of income (your highest bracket). Your effective tax rate is the average rate you pay on all your income (total tax ÷ total income).

How can I reduce my taxable income?

Common strategies include contributing to retirement accounts (401k, IRA), claiming deductions for mortgage interest, student loan interest, charitable donations, and taking advantage of tax credits.
