Common Questions & Guidance
Frequently asked questions regarding Income Tax Calculator.
What is a progressive tax system?
In a progressive system, tax rates increase as taxable income increases. Your income is divided into segments (brackets), and each segment is taxed at its respective rate. Therefore, your top marginal bracket is higher than your effective (average) rate.
What is the standard deduction?
The standard deduction is a fixed dollar amount that reduces your taxable income, depending on filing status. For tax year 2025 (filed in 2026), it is $15,000 for single filers and $30,000 for married couples filing jointly, per IRS Revenue Procedure 2024-40.
