How do I handle VAT and discounts?

Question

As an e-commerce business operating across multiple countries, I'm struggling to understand how to correctly apply discounts while ensuring proper VAT (Value Added Tax) calculations. My current system seems inconsistent, and I'm worried about potential legal and financial compliance issues. I need a clear strategy for handling VAT when running promotions, understanding whether discounts should be applied before or after tax, and how to maintain accurate financial reporting across different jurisdictions.

Handling VAT and DiscountsUnderstanding how discounts interact with VAT is important for international stores, particularly in the EU and UK where VAT compliance is strictly regulated.How the Calculation WorksStepExample (20% VAT, 10% discount)Original price (incl. VAT)£120 (£100 net + £20 VAT)Discount applied (10%)-£12 (applied to full incl. VAT price)Final price£108 (£90 net + £18 VAT)Compliance note: Shopify automatically handles VAT calculation on discounted prices for EU and UK stores. The VAT amount shown on the order reflects the tax on the discounted price, not the original price - which is the correct treatment for tax compliance.If you show prices inclusive of VAT (common in EU), ensure your Growth Suite campaigns display the discounted VAT-inclusive price in the offer - not the pre-tax amount.
