Form 15G declares estimated income and verifies non-deduction of tax, requires PAN and payer reporting in TDS statements. Form No. 15G under section 197A(1) and 197A(1A) requires individuals or persons (other than companies or firms) to provide PAN, status, residential and income particulars, estimated income and total income for the relevant previous year, and identification of the investment/account. The declarant must confirm the income is not includible in another person's total income and that tax on estimated total income will be nil or below the non-taxable threshold. A valid PAN is mandatory; false statements attract prosecution. Payers must allot unique IDs to received forms, report them in TDS statements, and may refuse declarations exceeding the non-taxable limit.
