Income-tax rate structure for 2026 sets surcharge, cess, and special slab rules across multiple taxpayer categories. Income-tax for the assessment year commencing on 1 April 2026 is charged at the rates in Part I-A of the First Schedule, subject to surcharge and a four per cent Health and Education Cess. The provision sets out special treatment for net agricultural income, alternative tax regimes, specified charging sections, differentiated surcharge slabs for various classes of taxpayers, and caps on total tax and surcharge in certain cases. It also defines domestic company and net agricultural income for the purposes of the section.
