Deadline change for tax estimate submissions requires Commissioners to follow a revised timetable and simplified proforma. The Board revised the internal submission timetable because monthly collection statements will be sent by the 30th of the following month; accordingly, 4 monthly and 6 monthly Budget Estimates for Income tax, Corporation tax and Interest tax must be furnished to the Board on the Board's revised due dates and Commissioners must rigidly adhere to them. The 9 monthly Estimates due date remains unchanged, but the Board simplified the proforma and requires submission in the new proforma (not form ITNS 71) addressed to the designated desk officer by the prescribed annual cut off.
