Dear Kumar,
The TDS limt upto 30/06/2010 is 120000 pa in case of rent and thereafter it is 180000 pa.
As mentioned above basic rent is 15000 pm totalling to 180000 pa and currently limit of 120K will apply in which case you have deduct TDS. Also service tax is chargeable on rent amt but which is not subject to TDS ie tax is not to be deducted on service tax portion.
from 01/07/2010 the limit is going to be 180K in which case your rent amount does not exceed the limit then you may not deduct the tax.
Rate of TDS is 10% for use of land, bldg, furniture & fitting and 2% for Machinery, plant and equipments. No surcharge and Education cess is applicable on this rate from 01-10-09.
Thanks & Regards
Hitesh
