Advance Tax Due 15 September 2026: The 45% Second Instalment Under the Income-tax Act, 2025
The 15 September 2026 advance tax instalment is the first September instalment under the Income-tax Act, 2025. Sections 404 to 408 set the 45% cumulative target; Section 425 charges a flat 3% on any shortfall unless 36% is already paid; capital-gains and dividend carve-outs survive. Worked examples.

I write on the income-tax beat here — ITR form selection and filing mechanics, the old-versus-new regime comparison, capital gains, the Section 87A rebate, TDS credit mismatches, and the interest that runs under Sections 234A, 234B and 234C. I work from the bare Act text and CBDT circulars rather than secondary commentary, and I put worked examples in using the numbers you actually see on the Income-tax Department portal. I'm writing for people filing their own return as much as for practitioners with a desk full of them.
