Income Tax Calculator Income Sources Deductions (Old Regime Only)
An income tax calculator is a tool that helps individuals and businesses estimate the amount of income tax they are required to pay based on their income, deductions, and other relevant financial information. It considers factors such as taxable income, tax brackets, deductions, credits, and other tax details to estimate your tax liability.
Income tax can be paid through tax deducted at source (TDS) during salary disbursement or via the income tax return portal managed by the Central Board of Direct Taxes (CBDT). Online tax payment provisions ensure individuals pay required taxes on earnings from all sources.
Understanding Income Tax Slabs
Income tax slabs are different income ranges taxed at varying rates. In India, these slabs are categorized into ranges, each with a specific tax rate. They determine how much income tax an individual must pay based on total income.
The slabs may change yearly based on new tax laws and regulations, so always refer to the latest guidelines.
The three categories of individual taxpayers in India are:
- Individuals (Below 60 years of age)
- Senior Citizens (60 years or more but less than 80 years)
- Very Senior Citizens (80 years or more)
