Hi,
Thanks for the info.
For reverse charge, two tax code can not be same
For reverse charge setup we need to have two code
1: With positive value/amount
2: with negative value/amount
For positive value code, if you use incoming invoice, it should say tax receivable
For negative value code, if you use incoming invoice, it should say tax payable.
Please check your sales tax posting profile, there is the sales tax direction is setup.
if you want you can share with us, we can help you.
