Dear, I'm glad to answer your question: the VAT return has been invalidated. Can I cancel if I check the input invoice? Answer: kissing is not allowed. After the VAT declaration is cancelled, the input invoice cannot be re-examined. If you cancel the VAT declaration, you can only correct the data errors in the previous declaration form, and you cannot recheck the input tax. You have to check whether the homepage of your VAT integrated service platform has expired. If so, yes, if not, no. I hope my answer can help you.
