Today is the last day to pay the fourth quarterly advance tax instalment for FY 2023-24. Taxpayers can now verify their tax liability as the AIS Compliance Portal has been fixed by CBDT to display correct data. Experts recommend taxpayers to engage with the tax department proactively and provide feedback if any discrepancies are observed. Failure to pay advance tax may result in penal interest. Certain categories of taxpayers are exempted from paying advance tax.
