Payment of Advance tax under wrong FY

This discussion addresses the issue of paying advance tax for the incorrect financial year, specifically FY 2019-20 instead of FY 2020-21. While some suggest getting the challan corrected by the Assessing Officer (AO) or filing a rectification for FY 2019-20 to claim a refund, others state that tax payments cannot be adjusted between different financial years. The consensus leans towards paying the correct tax for FY 2020-21 separately, as the wrongly paid amount may not be directly adjustable.
