Version 1.03:

Date: 08/09/2020

  1. Help section of e Invoice portal has been updated with new documents.
  2. The following Improvements have been done in Validations in IRN Generation API.
    • In case of Credit Note and Debit Note, tax rate can be passed with any value.
    • Passed IGST Value of Item will not be validated even actual tax rate is passed in case of EXPWOP and SEZWOP, if the passed value of IGST for that is ZERO.
    • Tolerance limit: The passed value should be between minimum and maximum values as explained here. Minimum value is considered as the rupee part of the calculated value minus one rupee and maximum value is taken as the rounded up to next rupee value of the calculated value plus one rupee.
      • Example 1: if calculated value for IGST of item A is 2345.34 then tolerance limit for passed value of that item is between 2344.00 and 2347.00.
      • Example 2: if calculated value of IGST of all items is 10241.00 then tolerance limit for passed value of IGST of all items is between 10240.00and 10242.00
  3. The ERPs shortlisted by GSTN have been enabled to register and test the APIs on the sandbox system. They will work like GSP in using the e-invoicing system.
  4. The E-Commerce Operator (ECO) have been enabled to register and test the APIs on the sandbox system. The brief note on operations of the e-commerce operator has been published on the https://einvoice1.gst.gov.in portal.
  5. The tax payers have been enabled to self-register for the e-invoice system, if they have crossed the aggregate turnover of the business with Rs 500.00 Crores during any of the previous 3 financial years of GST regime.
  6. ‘Generate EWB by IRN’ has been improved to enable the generation of EWB in case of export by passing the address of the port from where it is getting exported later.
  7. Mobile app for verification of QR code and signed e Invoice file has been released.

  1. The following improvements have been made in the validations of IRN generation:
    • Document Number accepts alphabets in small cases.
    • Check “The Document Date can be yesterday or today’s date” has been withdrawn.
    • In case, Recipient is SEZ unit or SEZ developer, the ‘Bill to’ State code should match with the state code of the Recipient.
    • In case of export transactions for goods, if e-way bill is required along with IRN, then the ‘Ship-To’ address should be of the address of the place/port in India from where the goods are being exported. Otherwise E-way bill can be generated later based on IRN, by passing the ‘Ship-To’ address as the address of the place/port of India from where the goods are being exported.
    • Check “Gross Amount of Item = Quantity X Selling Unit Price” has been withdrawn temporarily.
    • The round-off value for ' Round_off_amount' attribute to adjust final 'Total_Invoice_Value_INR' attribute can be between -99.99 and +99.99
    • The distance of transportation is validated against the auto-calculated PIN-PIN distance stored in the system. The allowed distance for transportation should be between +/- 10 % of auto-calculated PIN-PIN distance.
    • If the distance of transportation is passed as 0 (zero), then the system will consider it as request made by the tax payer, to consider the auto-calculated PIN-PIN distance for the generation of e-way bill and generate the e-way bill along with IRN.
    • The actual distance has to be passed in case the source and destination PIN codes are same and the allowed range of value is from 1 to 100.
    • In case of export of goods, if e-way bill has to be generated, then the address of port should have been passed as shipping address during generation of IRN.
    • Tolerance limit for ‘Passed value / amount’ has been improved by setting the value between actual calculated value / amount and calculated value / amount rounded up to next rupee.
  2. Auto calculated PIN-PIN distance is passed in the attribute ‘Remarks’ in the response payload, if the request has been made to get the auto calculated PIN-PIN distance for e-way bill generation.
  3. ‘Cancel IRN’ API can be used to cancel the IRN within 24 hours of generation of IRN.
