In September 2017, Amazon announced plans to locate a second headquarters in a metropolitan area with at least a million people. Cities needed to submit their presentations by October 19, 2017 for the project called HQ2. The $5 billion second headquarters, starting with 500,000 square feet and eventually expanding to as much as 8 million square feet, may have as many as 50,000 employees. In 2017, Amazon announced it would build a new downtown Seattle building with space for Mary's Place, a local charity in 2020.
Many U.S. states in the 21st century have passed online shopping sales tax laws designed to compel Amazon.com and other e-commerce retailers to collect state and local sales taxes from its customers. Amazon.com originally collected sales tax only from five states as of 2011, but as of April 2017, Amazon collects sales taxes from customers in all 45 states that have a state sales tax and in Washington, D.C.
