Section 234B: 1% per month (simple interest) on shortfall if advance tax paid is less than 90% of assessed tax liability. Section 234C: 1% per month for deferment — charged when quarterly installments fall short of the prescribed percentages (15%, 45%, 75%, 100%).

Can I pay advance tax in a lump sum? ▼
