Our VAT rate is being changed to 15% from the previous 5%.
We use AX 2009 at work and have implemented VAT with a combination of Sales Tax Group, Item Sales Tax Group and Item Sales Tax Group, under sales tax code named 5%.
Now for the new VAT rate, I have created a 15% sales tax code with value 15%.
Now my questions are,
1) Should I create a new Sales Tax Group to use the new Sales tax Code? Or should I just add the new sales tax code under the old Sales Tax Group.
2) If I am going to use the old sales tax group, should I remove the 5% sales tax code from under it? Or is there a way to disable it, because I don't want people still posting things under 5%.
3) Also, I want to be able to enable 5% in certain cases manually when an invoice has to be posted for customers who have contract supply (contracts signed before a May 2020 are eligible for 5% VAT until end of contract or July 2021, whichever is earlier).
Appreciate your support on what is the best option here. Thanks!
