I reserched the word 'Include tax' for all forums but I can not arrive to find the good answer.
so let me please post my questions.

I buy the products from japan and I sell to Europe. I am based in France.
so My business scale is very small so I don't want to complicate my accounts.
so I want everything includes Tax.
I tried all what explains but I don't arrive to show my shops as I wish.
product price shows always without tax.
Please help me your intelligence.
