# Frequently asked questions (FAQs)

## **Whenever I try to generate an e-invoice via ClearTax platform, I encounter "Unauthorized" error. How can I resolve this and generate LHDN compliant e-invoices?**

\
\
"**Unauthorized**" error occurs when ClearTax doesn't have the necessary permissions to submit e-invoices for generation on your company's behalf. There can be 4 scenarios in this case:

* **You haven't added ClearTax as an intermediary on your MyInvois portal**
  * Please follow the instructions mentioned in the guide [Add ClearTax as an intermediary on MyInvois portal](https://docs.cleartax.in/product-help-and-support/for-large-businesses/cleartax-e-invoicing-malaysia/onboarding/add-cleartax-as-an-intermediary-on-myinvois-portal) for detailed steps.

* **You have added ClearTax as an intermediary on your MyInvois portal but haven't given the permissions to perform actions on your behalf**
  * Visit MyInvois portal and edit the intermediary profile to give ClearTax access for interacting with LHDN on your behalf.

* **The TIN registered on the MyInvois portal is different from the TIN you are using via ClearTax platform**
  * The TIN mentioned on the ClearTax platform and is being used for submitting e-invoices is different from the TIN registered on your MyInvois profile. 
  * Please validate if both the TINs are same.

* **The TIN entered on ClearTax platform is incorrect**
  * LHDN expects taxpayers to remove any initial zeros that come after the TIN prefix for successful validation. 
  * For example, where the TIN of a taxpayer is ‘C01234567890’, the zero after the prefix ‘C’ needs to be excluded, resulting in ‘C1234567890’. 
  * Please make sure you have removed any initial zeros from your TIN when registering on the ClearTax platform.

## I am receiving the error "Issuance date time value of the document is too old and cannot be submitted" from LHDN. What actions can I take?

LHDN expects the e-invoice to be generated within 72 hours of document issuance. 

* It might happen that you are trying to generate an e-invoice for a document whose date & time falls beyond the 72 hours window. For such cases, adjust the date to ensure it is within 72 hours before submission.

* If you believe that the document submission date & time falls within the 72 hours window from the document issuance date & time, please check your timezone settings. 
  * By default the data that you send to ClearTax platform is processed in UTC given LHDN expects date & time to be in UTC. 
  * If you are sending the data in MYT from your end, please also change the setting on ClearTax portal to process this data in MYT. 
  * Follow the steps mentioned in the "[Set your timezone to MYT](https://docs.cleartax.in/product-help-and-support/for-large-businesses/cleartax-e-invoicing-malaysia/onboarding/set-your-timezone-to-myt)" guide for detailed instructions on the same.

## I am receiving the error "Maximum allowed document size 300Kb exceeded" from LHDN for my submission. How do I interpret this error?

As per LHDN guidelines, e-Invoice file size rules are as follows:

1. 5 MB maximum submission size;
2. 100 maximum e-Invoices per submission; and
3. 300 KB maximum per e-Invoice.

If you are receiving the above error, you might have already hit the "300KB" file size limit imposed by LHDN. 

* ClearTax has implemented minification of the submitted XML os JSON file to ensure your invoice meets the above mentioned limits.
* However, in our experience we have seen this happening for documents that has line items more than 150.
* We recommend reducing the number of line items to 150 to ensure you stay under the "300KB' file size limit and are able to successfully submit your e-invoice to LHDN.

## How many decimal points does ClearTax support for various e-invoicing payload fields?

* ClearTax supports upto 15 decimal places for the fields mentioned below:

  * TaxExchangeRate.CalculationRate 
  * InvoiceLine.Price.Value
  * InvoiceLine.InvoicedQuantity.Quantity
  * InvoiceLine.TaxTotal.TaxSubtotal.Percent
  * TaxTotal.TaxSubtotal.TaxCategory.TaxRate

* For all other amount related fields, ClearTax rounds off upto 2 decimal places.
