VAT & GST FAQ

How do I add VAT to a net price?

Multiply the net price by (1 + rate/100). Example: Net $100 at 20% VAT = 100 × 1.20 = $120 gross. The VAT amount is $20.

How do I extract VAT from a gross (VAT-inclusive) price?

Divide the gross price by (1 + rate/100). Example: Gross $120 at 20% VAT = 120 / 1.20 = $100 net. The VAT amount is $20.

Which country has the highest standard VAT rate?

Hungary currently has the highest standard VAT rate in the EU at 27%. Nordic countries like Denmark, Norway, and Sweden apply 25%. Switzerland uses a lower 8.1% standard rate.

Do I charge VAT on cross-border B2B sales in the EU?

For intra-EU B2B with a valid buyer VAT number, you typically apply the 'reverse charge' (0% VAT with a legal note). The buyer accounts for VAT in their country. Verify with the EU VIES system and your local tax authority.
