How to get intimations 143(1) for ay 07 and 08?

Notice u/s 245 means AO has the right to retrieve the tax shortfall of those years from present year's refund. 

Upto AY 2007-08 they took physical copies of  Tax credits i.e Challans and Form 16 /16A.  But from 2008-09 they are relying only on 26AS. 

If you have copy of tax credits for above years go and show it to your AO. The AO will ask you to submit it to AAYAKAR seva kendra . You have to write the no of pages and ur Mobile no on forwarding letter . A Computer sticker  [acknowledgement ] will be puton ur copy. You need to wait for sometime. So that the issue is addressed. Take a copy of ITR-V of those years also

Your local area Ao can provide it to you.
