IRP error 2182: Total taxable value does not match the lines
What the IRP says
Why it happens, in NIC's words
Sum of taxable amounts of all items should be equal to invoice level taxable amount.
What NIC says to do
Please check the request payload for the taxable value validation. Total Taxable Value = Taxable value of all line items
NIC's wording, from its published list of IRP errors, as read on 1 October 2026.
In plain words
The taxable value at invoice level (ValDtls.AssVal) is not the sum of the taxable values of the lines (ItemList[].AssAmt).
How to fix it
- Add up the taxable value of every line and put that sum in the invoice total.
- If a line was added, removed or changed after the totals were worked out, recalculate the totals.
- The IRP allows a small difference (about one to two rupees), not more.
Can you catch it before you upload?
Yes. The free pre-check on this site tests for it before you upload. It adds up the lines and compares the result with the invoice total, using NIC's tolerance.
