-  Sole Proprietorship / Partnership: taxed as per individual tax slabs (up to 30% + surcharge + cess)
-  LLP: flat 30% tax + 4% health & education cess on taxable income
-  Private Limited Company / OPC (turnover ≤ ₹400 Crore): 25% + 4% cess
-  Private Limited Company (turnover > ₹400 Crore): 30% + 4% cess
-  New manufacturing companies: 15% (concessional rate under Section 115BAB)
 Pro Tip Startups planning to raise VC/angel funding must incorporate as a Private Limited Company — investors rarely fund sole proprietorships or partnerships due to unlimited liability and lack of share issuance.
