As the income tax department now allows online ITR filing for the assessment year 2024-25, taxpayers must be aware of deductions they can get on their income tax. The last date for filing income tax returns (ITRs) for FY 2023-24 (AY 2024-25) is July 31, 2024. Starting FY 2023-24, the new tax regime has become the default tax regime that allows basic exemptions up to Rs 3 lakh. You may have failed to inform your employers of certain expenses and tax-saving investments, such as investments in the Public Provident Fund (PPF) or investments in ELSS mutual fund schemes. Or you may have missed submitting the required documents to claim house rent allowance (HRA), though you lived in rented accommodations during FY 2023-24. But taxpayers can still get deductions while filing ITR, even if you missed submitting some documents to your employer.
