Economic nexus, often called sales tax nexus, is a US sales tax obligation triggered by revenue or transaction volume in a state, without requiring a physical presence. Most states set the threshold at $100,000 in sales, and some also count 200 transactions. Once crossed, you must register for sales tax in that state and start collecting it from buyers there. Read our US economic nexus guide for the rules in every state.
The EU VAT One Stop Shop (OSS) threshold is €10,000 per calendar year. It applies to EU-based businesses and counts the combined total of cross-border digital services and distance sales of goods to consumers in other EU countries. Below it, you can charge your home country's VAT; once you exceed it, you must charge VAT at each customer's country rate. Businesses based outside the EU have no threshold and must collect EU VAT from the first sale. In both cases, you can use the OSS scheme to report your EU sales in a single return instead of registering in each country. Learn more in our EU VAT guide.
If your business is based outside the UK and sells digital services to UK consumers, you must register for UK VAT before your first sale. There is no minimum threshold. Quaderno tracks your UK sales from day one so you always know what you owe.
