Maryland's Amazon HQ2 incentive package leads the pack. Here's how other cities' proposals stack up.

Maryland lawmakers approved the so-called PRIME Act this week, an $8.5 billion package filled with credits, incentives and grants aimed at cementing a deal with Amazon for its second headquarters.

The package is the largest ever offered in Maryland, which has previously only offered deals topping out in the hundreds of millions. The offer is setting the bar for the country (and one Canadian city), though many cities and states aren't saying what they are pitching. In contrast, a small number of the 20 finalist cities say they included no incentives in their bids, or nothing more than is offered to any other business creating jobs.

Maryland's offer, which passed with bipartisan but not unanimous support, includes $6.5 billion in tax incentives and $2 billion in infrastructure and transportation improvements for the site in Montgomery County, one of 20 still in the running. Other sites in Port Covington in South Baltimore and the Old Goucher neighborhood didn't make the cut for the HQ2 project, expected to create 50,000 high-paying jobs and a $5 billion investment.

Here are the finalists and their offers, when details are publicly known. The findings were collected from news sources including Business Insider, CNET and several local newspapers and news radio stations.
