Google Checkout Tax Problem

developer wrote:Hello all! I'm using OC 1.4.8b and Google Checkout.

Total price is included with tax and shipping. And when I go to checkout page for GC, I see another tax calculation from Google. I don't want it to be calculated again by Google. I set my tax settings to "You will not charge tax." at Google Merchant Center. There is no state to apply taxes. How I can fix that? Thanks.

Tax rules: Only for NJ, VAT 7%.

Geo Zone: NJ, USA only.

Google Tax Setting: Empty at Merchant Center and Checkout Page.

There is PayPal button on the same page. It works well with total price. But GC Extension has a problem with my site. Shipping isn't calculated, tax is calculated again.

kraftandjute wrote:hello! Just wondering if this issue has been resolved? We are having customers check out - and shipping is not being calculated. Neither is tax. Someone suggested that I go into the google settings.. (i had to update) - so i made sure we had PA 6% sales tax - but again, neither tax nor shipping is calculating.

Also - it cuts off our options - and we have to contact customer to see the options they chose.

Is there a fix? I have disabled google checkout right now, as we need to make sure the customer is paying shipping.

Everything works good on the store checkout. i.e. when someone from MA makes a purchase of a taxable product, the tax (6.25%) is added. But when someone from, say, Rhode Island (RI) makes the purchase, no tax is added. Now, when I use google checkout, for a MA taxable product, even with an RI address, the tax is being added. I have attached an image showing the three scenareos:
1. MA taxable product, Shipping address in MA -> Tax charged. (GOOD)
2. MA taxable product, Shipping address in RI -> Tax not charged. (GOOD)
3. MA taxable product, Shipping address in RI -> Tax charged in Google checkout ( BAD)

We encountered an error trying to access your server at https://www. -- the error we got is Sending failed with HTTP response code: 401. Response body was: Failed to Get Basic Authentication Headers


This seems to be happening only with the new code but not the old code. If possible could you please tell me in which exact file(s) you have found the tax bug. I want to try copying just the bug fix code into my current files and see if that works.

						$zoneCode = (is_null($row['code'])) ? '' : $row['code'];

		$response->SetMerchantAuthentication( $merchantId, $merchantKey );
		$status = $response->HttpAuthentication();
		if (!$status) {
			error_log( "ControllerCheckoutGCheckout::callback authentication failed",3,DIR_LOGS."error.txt" );
			die('authentication failed');
