I have been selling on Shopify for three years. Last month I found out I had been paying sales tax I did not owe in four states. Nobody caught it.
I run an online store selling handmade leather goods. Started on Etsy, moved to Shopify in 2022, grown it to a point where it is my primary income. I have a bookkeeper who handles the monthly work and an accountant who does the year end filing. I thought I had the financial side covered properly
Last month I was doing a deeper review of my expenses than usual because I was trying to understand why my margins had been slightly lower than expected for most of last year. Not dramatically lower, just enough to feel off
I started going through my Shopify tax settings and comparing them against what I was actually required to collect and remit in each state
This took me several hours and a lot of googling about economic nexus thresholds and I am not going to pretend I understood everything perfectly. But what I found was that Shopify had been collecting and remitting sales tax in four states where I had not yet crossed the economic nexus threshold that would actually require me to collect it
Shopify's tax settings had been configured at some point to collect in those states and nobody had reviewed whether the thresholds were actually met. My bookkeeper was recording the remittances as tax payments which they were. My accountant was filing based on what had been remitted. Nobody was asking whether the remittances should have been happening in the first place
I had been overpaying sales tax in four states for about fourteen months
The process of reviewing whether I can reclaim any of that is still ongoing and may not be fully recoverable depending on the state. The amount involved is somewhere between four and six thousand dollars depending on what can be claimed back
The thing that gets me is that this did not require sophisticated accounting knowledge to catch. It required someone to periodically look at whether the tax collection settings in Shopify matched the actual nexus obligations of the business. That is a review that should happen at least annually for any ecommerce business and it had never happened once in three years
If you are running an ecommerce business on Shopify or any other platform and you have never reviewed your tax collection settings against your actual nexus obligations in each state, that is worth doing this week. The settings Shopify suggests during setup are not always correct for your specific situation and they do not automatically update as your business grows or your nexus situation changes
The mistake in either direction is expensive. Collecting when you do not need to costs you margin. Not collecting when you should creates liability. Neither one takes care of itself without someone actually looking at it periodically
