i think you should deposit TDS amount with one month interest because tds on payment credited on 31/3/2007 shall be deposited up to 31/5/2007 and now u r late so deposit tax with interest and filem return on 15th june.
As tax is deposited before filling of return so will be allowed in A.Y 2007-2008.
you should deposit TDS with interest. You have to pay simple interest at the rate of 12 per cent per annum from 1st june 2007 to till the date of actual payment in terms of Section 201. TDS return cannot be submitted unless interest for late deposit of TDS is paid
Expenses of the previuse year is not deductible in the current year.
However payment of bill received is to be made with deduction of TDS.
I find there no link between TDS and Deduction of exepnditure.
