Dear Yogesh
Generally TDS is deducted on " AMOUNT PAYABLE" before the intoduction of circular 4/2008 as mentioned by you. But after the introduction it has been cleared that as per the provision of section 194J " Any Person responsible for paying rent to a resident is required to deduct TDS" and Rent means
rent means any payment, by whatever name called, under any lease, sub-lease, tenancy or any other agreement or arrangement for the use of land , building , Plant & machinery , furniture & fittings,
And one thing is that Service tax paid by the tenant doesnt partake the nature of income of the landlord. The landlord only acts as a collecting agency for Government for collection of service tax. Therefore it has been decided that tax deduction at source (TDS) under sections 194-I of Income-tax Act would be required to be made on the amount of rent paid/payable without including the service tax.
So as per circular Any Amount payable means RENT as defined above but in other section ie. 194C,194J "AMOUNT PAYABLE" means any amount paid to payee in other words " GROSS AMOUNT" paid to payee. So in other section TDS is deductible on GROSS AMOUNT inclusive of service tax.
Hope ur doubts has been cleared.
