This document discusses advance tax payments for corporations in India. It explains that advance tax is paid in installments throughout the year rather than a lump sum at year-end. Corporations and individuals whose estimated annual tax liability is Rs. 10,000 or more are required to pay advance tax. Exceptions are made for senior citizens over age 60 without business or professional income. In conclusion, advance tax allows both the government and taxpayers to better manage tax collection and obligations over the fiscal year.
