Condonation of delay in filing tax-option forms: authorities may admit applications subject to specified eligibility conditions. The CBDT delegates power to admit and decide condonation applications for delay in filing Form No. 10-IC and Form No. 10-ID: Principal Commissioners/Commissioners for delays up to one year, and Principal Chief Commissioners/Chief Commissioners/Directors General for delays exceeding one year. Applications must show timely filing of the return, election of the relevant tax option in the ITR, and reasonable cause with genuine hardship; no application is maintainable beyond a three-year limitation and authorities should aim to dispose within six months.
