RET191175: Tax rate not in the permitted rate list

A line uses a rate the portal does not accept for that period. The permitted list changed on 22 Sep 2025 (GST 2.0).

Why it happens

  • A rate typed as a fraction (0.18) or with a typo.
  • A pre-Sep-2025 rate (12%/28%) used on a later invoice.

How to fix it

  1. Use a rate from the permitted list for the invoice date.
  2. If the tax amounts imply a valid rate, we propose that rate; otherwise decide the correct rate with your CA.
