Over 30,000 taxpayers have revised their I-T returns or filed belated returns and declared additional foreign assets and income of more than Rs 30,000 crore, Government sources said on Thursday. In line with its 'trust-first' approach, the Central Board of Direct Taxes (CBDT) had on November 16 last year, launched an awareness campaign under which messages were sent to taxpayers who had not disclosed high-value foreign income or assets in their ITRs for AY 2024-25. SMSes and emails were sent to 19,501 taxpayers with high foreign account balances or significant foreign income from interest or dividends above a specified threshold.
