Shopify merchants are experiencing a persistent tax calculation glitch where the system recalculates tax amounts after customers complete payment authorization. This creates two authorization charges on customer bank accounts—the original amount and an adjusted amount (typically differing by a few cents)—before the first drops off.
Key Issues:
Shopify’s Response:
Support has acknowledged this as a “known issue” since at least spring 2023 with “no known fix or workaround.” They’ve offered to submit feature requests but provided no timeline for resolution.
Merchant Impact:
Current Status:
The issue remains unresolved over a year later. It occurs intermittently with no clear pattern, making it difficult to track. Some merchants report updating product categories may reduce frequency, but doesn’t eliminate the problem. Most affected merchants now proactively explain it’s a Shopify platform issue beyond their control.
It really seems kind of silly that Shopify is largely ignoring this problem. Imagine this happening to a customer’s debit card or credit card when it is a large sum and locking up the money they need for other items.
They’re going to be ticked off and should be.
