<h1>E invoice reporting window imposed for large taxpayers; invoices and credit/debit notes must be registered within the set timeframe.</h1> A time-limit requirement has been imposed on electronic invoice reporting for high-turnover taxpayers: taxpayers meeting the Government's high annual turnover threshold must report newly issued invoices on the Invoice Registration Portal within a short prescribed window from the invoice date, with the portal validation rejecting late submissions; the restriction applies to all documents requiring an IRN, including credit and debit notes, and taxpayers below the threshold are currently exempt.
