I want to specify free shipping and no sales tax attribute over Google Merchant Center. I have done it with help of my shopping feed. But, my client came across with different requirement. They charged 7% sales tax only for Pennsylvania, US. Free shipping will be apply to Pennsylvania, US.

I have read Google Merchant Center help forum to get it done & edit my Tax & Shipping option from Google Merchant Center dashboard as follow.

But, when I searched to Google shopping so, in compare list Google shows only Free Shipping. No Sales Tax is not showing over there. So, How can I solve it?
