When the return is due to Amazon's own reasons, such as product quality problems, etc.; or when an order that has not been shipped is returned, the refund is a full refund, including the taxes paid and the shipping costs incurred by the self-service return, all will be refunded to you.

When it is not caused by Amazon, such as you don't want the item, or an order that has been shipped but not signed for, when a return occurs, the refund will only refund the price of the product, and the taxes and shipping costs incurred by the return will not be refunded.
