VAT Calculator

Calculate Value Added Tax for international sales and purchases.

Formula

VAT Amount = Net Price × VAT Rate
Gross Price (VAT-inclusive) = Net Price × (1 + VAT Rate)
Net Price = Gross Price / (1 + VAT Rate)

How to Calculate

Value Added Tax (VAT) is a consumption tax used in over 160 countries (not the US domestically, which uses sales tax). VAT is collected at each stage of the supply chain, with businesses remitting the difference between VAT collected on sales and VAT paid on purchases (input VAT).

To add VAT to a net price, multiply by (1 + VAT rate). For example, a €100 product with 20% VAT becomes €120. To extract the net price from a VAT-inclusive amount, divide by (1 + VAT rate): €120 / 1.20 = €100.

VAT rates vary by country and product category. The EU requires a minimum standard rate of 15%, with most countries charging 17–27%. Many countries have reduced rates for essentials like food, books, and medicine. If your business sells to customers in VAT-registered countries, you may need to register for VAT, charge the correct rate, file VAT returns, and manage the reverse charge mechanism for B2B cross-border sales.

Worked Example

A UK business sells software to customers in different scenarios.

B2C sale to UK customer (standard VAT 20%):
Net price: £500
VAT: £500 × 20% = £100
Gross price: £600
B2B sale to German company (reverse charge applies):
Net price: £500
VAT charged: £0 (customer self-assesses German VAT)
Invoice total: £500
Extracting VAT from a VAT-inclusive receipt:
Gross price: €240 (French receipt, 20% VAT)
Net price: €240 / 1.20 = €200
VAT paid: €240 − €200 = €40 (reclaimable as input VAT)

Why It Matters

If you sell goods or digital services to customers in countries with VAT, you may have registration and collection obligations. Non-compliance can result in fines, back taxes, and being blocked from selling in those markets. Understanding VAT is also essential for correctly pricing products in VAT-inclusive markets and for reclaiming input VAT on business purchases.

Practical Tips

  • Register for VAT in countries where you exceed the registration threshold—ignorance is not a defense.
  • Use the reverse charge mechanism for B2B cross-border sales within the EU to simplify compliance.
  • Track input VAT on business purchases meticulously—you can reclaim it, reducing your net tax cost.
  • Consider VAT compliance software if you sell into multiple countries—rates and rules differ everywhere.

Frequently Asked Questions

What is the difference between VAT and sales tax?
VAT is collected at every stage of production and distribution, with each business remitting only the tax on its value added. Sales tax is collected only at the final point of sale to the consumer. VAT tends to be more self-policing because each business has an incentive to report purchases (to claim input VAT credits), while sales tax relies solely on the retailer to collect and remit.
Do US businesses need to worry about VAT?
Yes, if you sell digital products, SaaS, or physical goods to customers in VAT-registered countries (EU, UK, Canada, Australia, etc.), you may need to register for and collect VAT. The EU's One-Stop Shop (OSS) simplifies this by allowing a single registration for all EU sales. Many e-commerce platforms handle VAT collection automatically.
What is the VAT reverse charge mechanism?
When a business in one EU country buys from a business in another EU country, the buyer (not the seller) accounts for VAT under the reverse charge. The seller invoices without VAT, and the buyer declares both the output VAT (owed) and input VAT (reclaimable) on their return, effectively netting to zero. This simplifies cross-border B2B trade.
