A company has taken office on rent for fy 13-14. The total rent for the year exceeds the limit of 180000. The company has booked rent for 6 months, i.e. April 13 to Sept 13 on 30th September 13 and deducted TDS on the same date. Is it correct or the Company should have deducted TDS every month when the rent becomes due. The rent payments were after september.
