In the Government Accounting System, each DDO (Drawing & Disbursement Officer) is associated with a specific Accounts Officer (AO), who processes the bills prepared by the DDO. Form 24G is a single monthly statement where the AO will consolidate the payment details from each of the DDO, for each type of deduction/collection (TDS-Salary/ TDS-Non Salary/ TDS- Non Salary Non Residents/ TCS) in a single form known as Form 24G.
