How does Zegel round?

To the cent, halves up (away from zero). Zegel works in whole cents, so the amount without VAT and the VAT always add up to exactly the total.

That depends on what you supply. The list is at FPS Finance; if in doubt, ask your accountant. Zegel calculates, it doesn’t choose the rate for you.

Yes, type a negative amount. Everything is then mirrored, including the rounding.
