If your TDS is being liablity before 31st march, then it should be paid on 7th april. It means if you paid the party before 31st march, then tds will be liable to be paid before 7th april (next mnth). If u Provision TDS on 31st march then u can pay before 31st may. TDS on salary for the m/o March will be liable to pay before 7th april.
Hence if it was a provision it was 31st May But as it is paid in April you can pay upto 7th May
