Corrected invoice without value-added tax
I was informed by a customer afterwards that an invoice from 2013 should be issued as exempt from sales tax instead of with sales tax (lecturing activity was retrospectively exempt from sales tax according to §4 No. 21 a) bb) UStG).
The customer's suggestion:
I will create a credit note with the current date for the amount at that time with sales tax, and at the same time, with the current date, a new invoice without sales tax.
So I will receive a refund of the sales tax from the tax office and should transfer the amount to the customer.
My problem:
The tax office will count the refund amount as profit within the income statement for the corresponding period.
Since this year I am trying to book as little profit as possible due to a fifth regulation, I am fighting for every euro that could be counted as profit.
Since I receive the money from the tax office and transfer it to the customer, there is actually no profit in reality.
Where is my misunderstanding or how can I turn the supposed "profit" back into a loss for tax purposes?
What I understand:
If I had many invoices with sales tax in this quarter, then the corrective invoice would reduce my advance payments for sales tax, because I do not pay all of the received sales tax to the tax office.
BUT, I do not have any more invoices in this quarter and through advance payments for sales tax, I have already paid all the applicable sales tax contributions to the tax office this year.
So, by issuing a credit note and a new invoice without sales tax for this quarter, I would receive a refund.
Best regards
P.S. Is such a late, retrospective exemption from sales tax actually permissible?
