A school district’s business office calls three weeks after a field trip. They’re tax exempt, they sent the certificate, and they were still charged sales tax on the gift shop bundle that came with the group visit. They don’t want the merchandise back. They want the tax back, and only the tax.
That is one of the more awkward requests to handle in Altru, because refunds there are built around items, not around the tax line that sits on top of them. Below is how to think it through, the options that tend to work, and what to sort out with your finance team before anyone touches the transaction.
Why a tax-only refund is tricky
In Altru, sales tax is calculated from how your taxable items are set up and which tax rates apply to them. When you process a refund or return, the tax generally follows the item: refund the item, and the tax tied to it comes back with it. What Altru is less clearly designed for is reaching into a completed sale and refunding the tax amount on its own while the item stays sold.
We’re not going to tell you there’s no way to do it, because configurations differ and Blackbaud updates the product. Before you build a process around any workaround, test a tax-only refund in a sandbox or training environment, or open a case with Blackbaud support and ask directly: “Can we refund only the sales tax on a completed order without returning the item?” Get the answer in writing and save it with your procedures.
Options that usually work
1. Refund the item and re-sell it without tax
This is the cleanest approach inside Altru when a full sale needs to be “re-rung.” Refund the original line (which returns the item price plus its tax), then record a new sale of the same item to the same constituent with tax handled correctly for an exempt buyer. The customer’s card sees a refund and a new charge, so the net difference equals the tax.
Before you rely on this, confirm two things:
- You have a supported way to sell to an exempt buyer without tax. Some organizations set up a non-taxable version of the item or a separate tax setup for exempt sales. If you don’t have one, that’s the real gap to fix.
- The original payment can still be refunded. Processor refund windows vary, and older transactions may need a different refund method.
The downside: two transactions instead of one, and reports will show the return. Add a note to the constituent record and the order explaining why.
2. Refund outside Altru, then adjust
Some teams issue the tax amount back through their payment processor or by check from accounts payable, then have finance record the matching adjustment in the general ledger. This keeps the item sale intact, but Altru’s revenue and tax figures will no longer match what actually happened unless someone records the correction. If you go this route, your finance lead needs to own it, and it should be the exception, not the habit.
3. Credit toward a future visit
For repeat group customers, a credit or discount on the next booking is sometimes simpler for everyone. It does not fix the tax you collected and reported, though. Ask finance whether the over-collected tax still needs to be corrected on your sales tax filing; in many states it does.
Talk to finance before you refund
Sales tax you collect is not your revenue. It’s a liability you owe to the state or local tax authority, and it gets reported on a schedule. A refund of tax affects that filing, so ask:
- Has the period that included the original sale already been filed? If so, how does finance want to claim the adjustment?
- Which GL account does sales tax post to from Altru, and will a refund reverse it correctly?
- What documentation do we need to keep? Usually it’s a copy of the exemption certificate tied to the transaction date.
A short conversation here prevents the worst outcome: a customer refunded on one side and tax still remitted to the state on the other.
Stopping it from happening again
Most tax-only refund requests come from a few predictable places:
- Group sales with exempt buyers. Schools, other nonprofits, and government agencies often book through group sales. Collect the exemption certificate when the booking is made, not at checkout, and flag the constituent record so staff can see it.
- Bundled items. When admission is combined with taxable merchandise or food, check which parts actually carry tax. Admission and merchandise are often taxed differently depending on your state.
- Item setup drift. Every so often, run a query of items flagged as taxable and have someone who knows your state’s rules review it. Items copied from older ones sometimes inherit tax settings they shouldn’t have.
- No written procedure. Write down which of the options above your organization uses for tax-only refunds, who approves it, and who tells finance. Then the next call from a school business office takes ten minutes instead of a week of emails.
Quick answers
Does refunding an item in Altru also refund its sales tax?
Generally yes; the tax tied to a refunded item comes back with it. Run a test refund in a sandbox to see how your setup handles partial quantities.
Can we just void the original sale?
Sometimes, if it’s still in an open batch or the same day. Once the batch has been committed and the payment has settled, a refund is usually the right path. Your batch and deposit process decides which one is available.
Who should approve a tax-only refund?
Someone in finance, since it changes your tax liability and possibly a filing that’s already been submitted. Front-line staff shouldn’t decide this on their own.
