Computation of Income (COI) of ITR – A Complete Guide 

Computation of Income (COI) is the most fundamental step in filing your Income Tax Return (ITR). It involves calculating the total taxable income under various heads and arriving at the correct tax liability for an individual, firm, company, or any other entity. The Income Tax Department requires accurate income computation to verify the correctness of ITR and determine tax dues or refunds.
