Hello

Can you be more specific please? Is it account receivable or payable?

Anyway, the setup is on tax codes window. Tax Method decides at which level tax amount should be handled.

I added for you help description

Tax Method Tax Received
The method used to define how to handle tax received amounts.
Invoice Entry - tax is posted when the invoice is entered. 
Final Posting - tax is posted in connection with the final entry. Final posting is not valid if the tax type is Use Tax.
Payment - tax is posted at the time of payment.
No Tax - no tax is posted. This is valid only if the tax type is No Tax. Transactions with this tax code type are not transferred to the tax ledger.

Tax Method Tax Disbursed
Invoice Entry means that the tax is posted when the invoice is entered.

Final Posting is not used for tax disbursed.

Payment means that the tax is booked at the time of payment.

No Tax means that no tax is posted. No Tax is only valid if tax type is No Tax.

Hi the flow for advanced invoices is usually as follows (assuming a full payment):

Create Invoice                       / Advance Invoice (AR=IP17/IP19, Tax=IP23/IP25 )

Receive Payment                 / Advance Invoice Reversed (AR=IP17/IP19, Tax=IP23/IP25)

                                                / Received Payment (AR=PP39, Tax PP38/PP40, PP1)

Create Final Invoice            / Final Invoice (AR=IP2, Tax=IP4, Revenue=M28)

OffSet Payment vs Final    / Received Payment reversed (AR=PP39, Tax PP38/PP40, PP1)

Payment Postings

Final Invoice

Automatic Offset of the received payments with the final invoice.

The example above works with statistical accounts on the advance invoice entry. 

In your case the bold Posting Types might need to be setup against a real tax account.

Hello, 

Thank you for your message.

The problem is that we want to declare a VAT at the advance invoice posting.

So in the standard flow as you can see the VAT postings are reversed at the advanced invoice payment, that’s where we have our problem.

Hi,

if you post all bold marked posting types against a real tax account the

..tax from the advance invoice is posted against real tax account

..if the adv. invoice is fully paid the tax from the advanced invoice reversed and “replaced” by the tax of the advance payment

..on the final invoice again the tax is reversed from the payment and replaced by the tax of the final invoice

Kind regards

Ralph
