Chapter 14 Core Formula Sheet

Quick-glance formula revision for examination and numerical problem-solving:

  • $$Taxable Income = Gross Total Income - Deductions$$
  • $$Total Tax = Tax on Slabs - Rebate u/s 87A + 4% Cess$$
  • $$Intra-state: CGST = GST Rate2, \; SGST = GST Rate2$$
  • $$Inter-state: IGST = GST Rate$$
  • $$Net GST Payable = Output GST - Input Tax Credit (ITC)$$
  • $$Electricity Bill = Fixed Charges + ∑(Units in Slab × Slab Rate) + Duty/Cess$$
