Advance Tax Under the Income-tax Act, 2025
Applicability and threshold:
Advance tax under the Income-tax Act, 2025 is governed by Sections 403 to 408, with interest provisions contained in Sections 423, 424, and 425. Every assessee, including individuals, firms, LLPs, companies, and non-residents, must pay advance tax if the net tax liability after considering TDS and TCS is Rs. 10,000 or more. Resident senior citizens without business or professional income remain exempt from this requirement.
Computation of advance tax:
Under Section 405, advance tax is computed as the tax on the assessee’s estimated total income for the year, reduced by the TDS and TCS expected to be credited during that year. This net figure represents the advance tax payable and must be discharged in instalments during the course of the tax year.
Instalment schedule for regular assessees:
For most assessees, this liability is paid in four instalments under Section 408: 15% by 15th June, a cumulative 45% by 15th September, a cumulative 75% by 15th December, and the full 100% by 15th March.
Instalment schedule for presumptive taxpayers:
Assessees who opt for presumptive taxation under Section 58, corresponding to the erstwhile Sections 44AD(1) and 44ADA(1) of the 1961 Act, follow a different schedule. They are required to pay their entire advance tax liability in a single instalment, on or before 15th March, rather than in four instalments.
Income arising after 15th March:
Where specified income arises after 15th March, the tax on such income remains payable and continues to be treated as advance tax for that tax year under Section 408(3), provided it is paid on or before 31st March. However, since this falls after the original due date, such payment attracts a short spell of interest under Section 425 for the delay.
Interest on shortfall:
Separately, a shortfall of more than 10% against the assessed tax attracts interest under Section 424.
