Non-deductible expenses

If you are subject to VAT, I think you can solve it this way.

Because if the VAT recovery percentage is 0%, an amount will indeed be added (for foreign purchases) via your vAT declaration. That way, you still pay VAT on an expense that was private.

The only slight problem you encounter in Dexxter is that you cannot set the professional use percentage to 0.00%. They do not allow that. So you have to set it to 0.01%, which is fine.

Okay, the impact on your accounts is negligible and you've solved the problem. So I think that's a good way to go.

Are there any other people who do it this way?

So, it is permitted from an accounting point of view. If the developers are reading this: is it possible to allow a 0% professional percentage in the application? If necessary, with a pop-up warning.
