Frequently Asked Questions (FAQ)
Essential answers about value-added tax, EU reverse charge, OSS, and US sales tax.
Q:What is the difference between Net (VAT-exclusive) and Gross (VAT-inclusive)?
The Net price is the seller revenue before tax. The Gross price is the total amount paid by the end customer, including value-added tax (Gross = Net × (1 + Tax Rate)).
Q:How does the EU VAT reverse charge mechanism work for B2B transactions?
When an EU business sells to a VAT-registered business in another EU country, VAT is zero-rated on the invoice. The buyer self-accounts for the VAT in their own domestic tax return.
Q:What is the EU One-Stop Shop (OSS) scheme for B2C sales?
For cross-border consumer (B2C) sales exceeding €10,000 annually across the EU, sellers must charge the VAT rate of the buyer’s country and declare it via the centralized OSS portal.
Q:How does US Sales Tax differ from European VAT?
VAT is a multistage tax collected at every step of the supply chain with input tax credits. US Sales Tax is a single-stage tax levied only at the final point of retail sale to consumers.
Q:What constitutes economic nexus for US sales tax?
Out-of-state remote sellers establish economic nexus when their sales into a state exceed certain statutory thresholds (commonly $100,000 in gross sales or 200 separate transactions annually).
- Gross: Total amount including VAT.
- Net: Base amount before VAT.
- Rate: VAT percentage (e.g., 20%).
What is VAT calculator?
- EU B2C Scenario: If sold to a retail consumer in Germany, the engine applies the standard 19% localized VAT on top of the net price, yielding a €166.60 gross invoice.
- EU B2B Scenario: If sold cross-border to a registered business in France, the algorithm validates the VAT ID and automatically applies the Reverse Charge Mechanism, legally stripping the tax from the invoice and maintaining the 140 USD/€140 gross target.
- US Sales Tax Scenario: For a transaction in Los Angeles, California, the engine bypasses VAT entirely and applies compounding state, county, and municipal retail sales taxes based strictly on the destination zip code.
| Tax Framework | Processing Mechanics | Global Trade Application |
|---|---|---|
| EU VAT (B2C) | Destination Principle (OSS) | Indirect tax is calculated based on the end-consumer's location; merchants remit consolidated taxes via the EU One-Stop Shop (OSS). |
| EU VAT (B2B) | Reverse Charge Mechanism | Cross-border tax liability shifts entirely from the supplier to the registered business buyer, resulting in a 0% tax invoice. |
| US Sales Tax | Economic Nexus / Destination Sourcing | Highly localized, non-recoverable retail taxes triggered only when a merchant exceeds specific revenue or transaction volume thresholds in a given US state. |
| Margin Reconciliation | Pre-Tax & Post-Tax Isolation | Mathematically separates the fluctuating regional tax burden from the core product cost, ensuring dynamic invoice generation never cannibalizes net profit targets. |
