Tds on contractor f.y. 09-10 deducted but paid after 31/3/10

Dear Sir,

Client, deducted TDS on contracts for F.Y. 2009-10, but paid it in May, 2010 in F.Y. 2010-11, before due date of filing IT returns, whether such expenses allowable in 2009-10 or not ? 

Kindly advice,

Thanks & regards,

Valerian Dsouza
