# Why does entering a VAT ID affect my e-invoice?

**Why does entering a VAT ID affect my e-invoice?**

If a customer enters a **valid VAT ID** at checkout, FastSpring automatically **exempts them from paying VAT**. This is because the buyer takes responsibility for handling VAT on their end.

* **If the VAT ID is missing or invalid, VAT is charged**, as the buyer is assumed to be an end consumer.
    
* **A VAT ID doesn’t mean a business has to pay tax upfront**—it means they are recognized as a taxable entity that handles VAT differently.
    
* Since FastSpring **does not charge VAT** when a valid VAT ID is provided, an **e-invoice is not issued**, as there is no tax amount to report.

**What if I left the Tax ID field blank?**

* If you **did not enter a Tax ID**, FastSpring assumes you are an **individual consumer**, and **VAT is charged** accordingly.

**Where can I get further assistance?**

If you've checked all the above and still haven’t received your e-invoice, please contact:
    
* **FastSpring Support:** Visit the **[Consumer Portal](https://fastspring.com/consumer-support/)** or submit a ticket through their support team.
