OSS VAT Location
Destination-country VAT
Use this when OSS is active, the merchant has opted in, or the relevant EU cross-border threshold treatment requires destination VAT.
Store-country VAT
Use this only when the merchant is below the relevant threshold and has not opted into OSS treatment.
Why there is no automatic annual turnover tracker
Sales outside WooCommerce can count toward legal thresholds. The plugin therefore does not assume WooCommerce order totals represent the merchant’s complete annual cross-border turnover.
