What you're seeing
You issue a refund, but ServiceTitan adds sales tax to the refund amount even though the original charge wasn't taxed (or the customer is non-taxable). The refund comes out higher than what the customer originally paid. This can affect a single refund or every refund that uses the same refund task.
Where you see it: the refund or adjustment invoice on the customer's account.
Where you fix it: Pricebook > Services (the refund task's Taxable setting).
Why this happens
There is 1 common reason.
Reason 1
The task used for refunds is marked as taxable in the Pricebook.
When a taxable task is added to a refund or adjustment invoice, ServiceTitan calculates sales tax on it the same way it would for any taxable line item.
How to fix it
Run these steps in order.
Note: You need Pricebook permissions to edit Pricebook services. If you don't have it, contact your administrator.
Caution: Before reprocessing a refund, cancel any earlier attempts for the incorrect amount in the Transaction Gateway. This avoids issuing duplicate refunds to the customer's card.
Caution: Clearing the Taxable setting stops tax on future refunds. It does not change refunds or adjustment invoices that were already created — those have to be corrected on the invoice itself (Step 7).
1Clear the Taxable setting on the refund task
Use this to stop tax on future refunds and correct any refund already created with tax.
Go to the navigation bar and click Pricebook.
In the side menu, click Services.
Search for the task you use for refunds.
Click the More icon for that task and select View/Edit Service.
In the Details tab, clear the Taxable checkbox.
Click Save.
If a refund or adjustment invoice was already created with tax, remove the labor task from the adjustment invoice (or the refund task from the refund invoice) and re-add it so the balance recalculates without tax.
✓ Done · New refunds that use this task no longer include sales tax, and the corrected refund total matches the amount the customer originally paid.
