Want to check TRNs within your ERP system?

Why is checking a TRN important?

Verifying the TRNs of your customers and suppliers is a legal requirement in many parts of the world, including the European Union. This regulation is imposed by authorities as they seek to improve reporting accuracy and reduce VAT fraud. If your business is not checking and verifying TRNs as standard in every transaction, you could be exposed to the risks associated with non-compliance.

Invalid, incomplete, or absent TRNs undermine invoices, potentially leading to input tax credits being denied for the buyer and penalties for the issuer. In the digital age, failure to submit a verified TRN can be uncovered by tax authorities easier than ever before – either through automated checks or at a formal audit.

Businesses should treat TRN verification as a mandatory step in the recording of any transaction within their systems; helping to protect themselves from VAT fraud, maintain accurate financial records, and eliminate the risk of penalties.
