Advance Tax Final Instalment Due March 15; Payment Options and Tax-Saving Tips

The deadline for paying the fourth and final instalment of advance tax for FY 2025-26 is March 15, 2026. Taxpayers with net tax liability of ₹10,000 or more after TDS and credits must pay to avoid interest under Sections 234B and 234C. Payments can be made via the Income Tax Department's e-filing portal, including by credit card, though processing fees may apply. Senior citizens without business income are exempt. Additionally, taxpayers should complete tax-saving investments by March 31 to claim deductions under the old tax regime.
