The Central Board of Direct Taxes (CBDT) has made Form 173A mandatory for eligible investors seeking income-tax exemptions on interest earned and capital gains arising from investments in government securities. The requirement was introduced under the Income-tax (Seventh Amendment) Rules, 2026, notified on October 19, 2026.
The amendment inserts Rule 281A into the Income-tax Rules, 2026, prescribing the information that eligible taxpayers must submit to claim exemptions under Schedule IV of the Income-tax Act, 2025. The rules came into force upon publication in the Official Gazette.
The exemption provisions, effective from April 1, 2026, cover qualifying interest income and capital gains from government securities, subject to the applicable conditions.
