Good afternoon!
The situation is as follows:
The client signed an act on the completion of all work
On October 1, he submitted reports to the tax
office. After that, the client checked and was not satisfied with part of the work, agreed and I returned part of the funds.

Now the client is asking to redo the last act for the amount that I returned to him, what should I do in such a situation, I will not be able to redo the tax reporting

Answer 1

This is done through an adjustment in the period after the reporting period, both for you and for the client. Alternatively, you can submit an updated report.
