Thanks, Rob! Your suggested fix via the support ticket for Merchant Technical Services did the trick! I just wanted to share your repsonse in the forum, in case someone else has a similar issue: it turned out the PayPal button was set to a fixed / static tax rate within the configuration of our PayPal account. To resolve this, just follow these steps: - Navigate to https://www.paypal.com/ and log in to your account. - Click on "Profile" - Click on "My selling tools" - Find "PayPal buttons" (top of the list called 'Selling online') and press "Update". In here, find which button is the one in use on your website. You can usually recognize it bay the name. Once you found your particular button: - Click "Action" followed by "Edit button". In the next screen find the "Tax" header and adjust the tax accordingly. Note: You could perhaps also have submitted some 'advanced variables' to set the tax rate. You can find these clicking on "Step 3: Customize advanced features (optional)". Once you've changed everything, click "Save Changes" to save the changes. These will take effect immediately. You will not need to re-copy the code of the button over to your site. Again, thanks Robert for figuring this out! Julia
