Fiscalization rules in Lithuania—how to process electronic receipts?

In Lithuania, e-receipts are recognized as valid fiscal documents under the i.EKA system, but their issuance is entirely optional and depends on both the buyer’s consent and the seller’s technical capability. Businesses are not obligated to offer e-receipts, and customers can always request a printed version; if e-receipts are provided, buyers can remain anonymous, and no personal data is collected by tax authorities.
