Business Validation Error: We’re sorry, QuickBooks encountered an error while calculating tax. Try reselecting the tax rate or reentering the product/service item and saving the form again

What It Means

This error can occur for users with a Global Tax Model (non-US) when a Tax Rate is used for a transaction that does not have a Sales Tax rate. Generally, this happens for tax rates defining a PurchaseTaxRate and not both, e.g., “GST on non-capital”.

Alternatively, it may occur when the QuickBooks Online Automatic Sales Tax (AST) feature is enabled, but QuickBooks is unable to calculate the tax.

How To Fix It

Synchronize the transaction with the default tax code:

  1. Click the gear icon on the top right corner of Synder app -> Taxes tab.
  2. Select Default tax code. From now on, it will be used at any time when the rate is missing.
  3. Click Update on the bottom of the page to save your settings.
  4. Synchronize the failed transaction again.
