We have filed the return of income for the assessment year 2009-10 without mentioning Domestic/Non Domestic Company ie status was not filled in the return. Our processing of return of income u/s 143(1) was completed as Non Domestic company by the system and charged Income Tax @ 40%. Our Assessment was also completed u/s 143(3) as a Non Domestic company although our company is a domestic company since the date of incorporation ie 19.03.1983. Our previous Assesments were completed as Domestic company. The Income tax is payable @ 30% as Domestic and 40% on Non Domestic. Please advice the action to be taken by us for correction of this error and where the mail/correspondance to be made.
