Price will no be increased

Hi ,
I'm wondering why the pice will not be increased automatically if I put in the price without tax.
(see picture)
I set my tax to 19% and enabled it in my new product

What can I do ?

Thanks
Tom

Hi Tom,
Did you set the "Product tax category" option of your product to your tax category ?

Hi Mohamed

Sure, now can you show me how did you configured the tax rate of your steuersatz 19% tax category through "Hikashop->System->Taxes" ?
