Mobile App Developer FAQ
Do I need a US company to publish on the App Store?
No, you can publish from almost any country. However, having a US LLC or a company in a country with a US tax treaty can significantly reduce the 30% withholding tax on US sales.
How does VAT work for app sales?
Apple and Google generally act as the 'Merchant of Record' and handle VAT/GST collection and remittance for consumers in most countries, simplifying your tax compliance.
Where is the best place to incorporate an app studio?
Popular choices include the US (Wyoming/Delaware LLCs for low maintenance), UK (favorable tax treaties and IP laws), and Estonia (0% tax on reinvested profits, great for growing studios).
