I google translated that, it means taxable in English. Actually this is not how you should show the pre tax total in SambaPOS. It would appear you have not setup SambaPOS with your tax settings and are just using this single calculation to show the pre-tax total. It’s a guess but it looks like that.
Your tax model will just be like any other basic tax model out there. And even though you might feel it is easier to add just a simple calculation like this in your receipt template, it actually means you are not storing any of your business accounting data in SambaPOS correctly to handle tax. When comes the time you need to provide this information to your accountant or tax department, you won’t easily have this data ready. That is why it is very important to use the tax features built into SambaPOS so you store this information correctly. For example, possibly some items you sell or some services might not be taxable? And even if not, it is far better from an accounting point of view to store this information correctly in your POS software.
