I got an intimation u/s 143 stating the Tax Credit Mismatch because of wrong TAN number keyed in while filing return of income.
Now what i should do in response to intimation
Whether I should file revised return or i should send a letter to ITO
they gave note that it must be answered with in 30 days but by today that 30 days time is expired, time lapsed because i made delay
Now what will be the consequence and what is the remedy ?
