# Fishbowl: 'Tax rate already used as line item'

> A tax rate you selected is already applied to another line item on this sales order.

## What it means
The tax rate you selected is already associated with a line item on this sales order. Fishbowl prevents the same tax rate from being used multiple times in conflicting ways, so the system is alerting you to this existing usage.

## What to check
- Look at each line item on this order and identify which one already uses this tax rate.
- Decide if you need to use a different tax rate for your current action.
- If the existing usage is wrong, consider modifying or removing it before reapplying the rate.
