Understanding Income Tax Return (ITR)

An Income Tax Return is a form where you declare your income, expenses, tax deductions, investments and the taxes you have paid during the financial year. The Income Tax Department use this information to determine your tax liability, process refunds if any, and ensure compliance with the law.

In India, there are different types of ITR forms—ITR-1, ITR-2, ITR-3 and so on—depending on your income sources, profession and residential status. Selecting the correct form is the first step to a smooth filing process.

Who Should File ITR?

Filing an ITR is mandatory for:

• Individuals with gross total income exceeding the basic exemption limit (₹2.5 lakh for individuals below the age of 60 years, ₹3 lakh for senior citizens, and ₹5 lakh for the super senior citizens).
• Companies, firms, and LLPs, regardless of income.
• Individuals who want to claim their income tax refund.
• Residents with foreign income or assets.
• Those who have deposited large sums in bank accounts, incurred high expenditure on foreign travel, or paid high electricity bills as per specified limits.
