Urd purchases

No if bills are available it will not create any problem for claiming expenses in income tax.

no, income tax cant disallow such expenses....

Vat--- you cant claim input tax credit if you are purchasing form unregistered dealer.

although we dont what is your case clearly, can you elobarate a little to get clear picture of what excatly going??

My concern was with income tax. But even for vat I think for urd purchases, we first pay the tax & then claim setoff in next month isnt it!
