Introduction
Sales tax problems rarely show up when it’s convenient. For CPAs and bookkeepers, they usually appear right when you’re trying to finalize a return or reconcile books for filing. What looked like a clean setup turns out to be misconfigured, incomplete, or out of date—and suddenly you’re stuck cleaning up a mess someone else didn’t catch.
These kinds of oversights don’t just cost time. They can chip away at your credibility with the client, even when the problem started somewhere else.
We help CPAs and EAs avoid these stress points by supporting the setup, cleanup, and monitoring of sales tax systems like Avalara AvaTax—so you’re never blindsided during busy season.
When One Missed State
Becomes a Big Problem
Most clients don’t understand nexus rules. They assume sales tax is handled automatically, especially if they’re using software like AvaTax or a platform like Shopify. But selling into a new state—without registering or collecting properly—can create a snowball of issues.
- The client crosses a state’s economic nexus threshold
- They don’t register or collect tax in that state
- They continue selling, unaware of their growing liability
- You find out during a year-end review or return prep
We help spot these risks early by reviewing activity across platforms, checking nexus exposure, and confirming registration status—before noncompliance turns into a letter from the state.
Why Tools Like AvaTax Still Need a Human in the Loop
AvaTax is powerful, but it’s not plug-and-play. It depends on accurate setup, tax code assignments, product classification, and exemption handling. It doesn’t know your client’s business unless someone tells it.
- Are exempt sales being excluded correctly?
- Are items mapped to the right tax codes?
- Are new sales channels triggering errors in reporting?
- Does what’s in AvaTax match what’s in QuickBooks Online?
We work with your team to audit AvaTax setup, fix misconfigurations, and ensure that what gets reported is what actually happened. It’s not about replacing automation—it’s about making sure it works as intended.
Ecommerce Sales Tax: The Trap No One Warns About
Ecommerce clients are the fastest-growing—and most at risk. They sell on multiple platforms, collect inconsistent data, and assume automation covers everything.
- Sales tax settings differ across Shopify, Amazon, and Square
- Reports don’t match up with accounting systems
- Nexus exposure grows without any filings
- Clients don’t know what’s being filed—or not filed—on their behalf
We support CPAs by handling the sales tax complexity that comes with ecommerce growth. From syncing platforms to reviewing filings, we bring clarity to what’s often a disconnected system.
“Sales tax mistakes don’t just cost time—they can damage trust. We help CPAs stay ahead of the mess.”
