Understanding Income Tax: A Comprehensive Guide

What is Income Tax?

Income tax is a tax levied by the government on the income earned by individuals and businesses. This tax is a significant source of revenue for governments, used to fund public services such as education, healthcare, infrastructure, and social security.

How Income Tax Works

1. Taxable Income: Income tax is computed based on taxable income, which includes wages, salaries, bonuses, rental income, investment income, and other earnings. Deductions, exemptions, and credits can reduce the taxable income.
2. Tax Brackets: Many countries employ a progressive tax system, where the tax rate increases as the income increases. Tax brackets define the income ranges subjected to different tax rates.
3. Filing and Payment: Taxpayers are required to file an income tax return annually, detailing their income and applicable deductions. Taxes owed are typically paid quarterly or annually, depending on the taxpayer’s income and country-specific regulations.
