Cancellation of invoice

Once filed then no way for Cancel. But, You can prepare Credit Note....

Section 16 states that a person shall be entitled to the credit of any input in respect of any supply of goods or services or both if: 

a. He is in a position of tax invoice / Debit note issued by the supplier
b. He has in his position the goods or services or both
c. Tax charged in respect of such supply has been actually paid to the Govt
d. He has furnished the return u/s 39

Conclusion: You can treat the amount paid by you as input credit and utilise the same for subsequent payments if you have issued a credit note to the party (Condition a) and furnished the same in returns u/s 39 (condtion d)
[Since condition b and c are already satisfied ]

Thanks for your reply appricaible

My query is in regards to Cancellation of Export Invoice and Issued new invoice at present date is allowed or not?

Case is: I have already issued export invoive with LUT on Dec 5 2018 and sent the material on port by generating the e way bill with the same invoice and this material was exported against LC. Afterwards i get to know that the invoice to be prepared should be after date of LC and now i cancelled the previously issued invoice and raise the new export invoice.

My Query is did i have done correct or not? Or there is any other solution for the same.

Thanks
