Why Your e-Invoice Request Shows “Invalid TIN” and How to Fix It



Introduction

When submitting an e-Invoice request using TimeTec Parking system, it is important to ensure that all tax-related information provided is accurate and aligned with official records. One of the most common issues encountered by users is the “Invalid TIN” error, which prevents the request from being successfully submitted.

This article explains why this error occurs and provides a step-by-step guide to help you verify and correct your Tax Identification Number (TIN), ensuring a smooth and successful e-Invoice submission process.



Process
When submitting an e-Invoice request, the system may return an “Invalid TIN” error. This happens because the TimeTec Parking system performs a real-time validation with LHDN (Inland Revenue Board of Malaysia) to ensure that the Tax Identification Number (TIN) provided is correct and active.

            

1. The “Invalid TIN” message may appear due to one or more of the following reasons:
      - TIN is not registered: The TIN does not exist in LHDN records.
      - TIN is inactive: The TIN has been deactivated or is no longer valid.
      - Mismatch with registered details: The TIN does not match the provided, MyKad number (for individuals), or Business Registration Number (BRN) for companies.
      - Incorrect TIN format or entry: Typographical errors or incorrect format during input.


2. How to Resolve the Issue
      a. Verify TIN via MyTax Portal
            - Visit the MyTax portal (LHDN)
            - Use the “Find TIN” function
            - Enter the relevant details (MyKad or BRN)
            - Confirm whether the TIN is valid and active
            

            



      b. Cross-Check with Finance/Accounts Department
            - Ensure the correct TIN is being used
            - Confirm whether the company is using a new or old BRN and the TIN provided matches official records

      c. Ensure Data Consistency. Double-check that:
            - MyKad / BRN matches the TIN exactly
            - No extra spaces or incorrect characters are entered

      d. Retry Submission
            - After verification, resubmit the e-Invoice request in the system
