Compliance of section 201(1)

Dear sir, my doubt is In case a deductor failed to deduct tax at source and if he pays interest as required by section 201(1)(amended), whether mere obtention of certificate in form No. 26A and annexure thereto from an accountant is sufficient compliance or whether the deductor should file a return of TDS ? Should we inform the income tax authorities that we have paid interest as per section 201 (1) ? If so how ? Kindly help me. Thank you.
