# I’ve integrated my Zoho Books account with Avalara, and I use Avatax to file my tax return. Is it possible to void an invoice after filing my tax return?

Avalara does not allow you to update the transactions which are filed in the tax return. So, you cannot void the invoice when it is part of the return that was filed through Avalara.

And, since Avalara and Books are integrated, you cannot void the invoice in your Zoho Books account as well.
