If you're adding sales order detail directly from the sales admin screen, you should be able to reverse calculate the amount you need to input without tax and the tax amount to charge. Both fields should be available for you to edit. I won't be able to tell you what amount to put, since I won't know your tax rate. :(

Thanks,

Dear Stephen,

Sorry for not understanding this.
Do you mean the following.

- add an item (in this case an article of €
- Calculate the tax (in this case 21%) and add this tho the article.
- Change the price of the article to €1.10

I do not see a field to add the tax (see screenshot below)

Regards, Ton

Add the sales order detail item and its price (without tax). You can click on Recalculate All and it will add back the necessary tax for that item. The tax amounts appear under the sales order (not the individual sales order order detail line items).

Thanks,
