Hello @Smilynic ,

If you are wanting tax entries that are entered on a JE to show up on tax reports, then you cannot just apply a code to a sales or purchase line in a JE.  You have to enter the tax account on a separate line and then tab over to the Sales Tax column and enter the correct tax code.  This applies to either sales or purchases.  See below for example of a purchase:

This behaves exactly as it did in Desktop.  If you tried to put a tax code on Line 1, it would not populate in sales tax reports or on the return.  Designating the tax account to a separate line on the JE will, as long as the Sales Tax field is mapped to the proper line on the return.

Hope it helps.

All the best,
