## Details

| Attribute | Value |
| --- | --- |
| Status code | 400 |
| Error code | `transaction_cannot_be_revised_with_tax_higher_than_grand_total_or_negative_tax` |
| Error message | Cannot revise transaction with a valid tax_identifier when the tax amount is higher than the grand total or tax is negative. |

## Common causes

- A valid tax_identifier is being passed, but the transaction's tax amount is higher than the grand total.
- A valid tax_identifier is being passed, but the transaction's tax amount is negative.
- Revising a transaction with a valid tax_identifier would end in a tax refund that cannot be performed when tax amount is higher than the grand total.

## Common solutions

- Do not specify a new tax identifier.
- Cancel the transaction and create a new one.
