The City of Worcester is digging deep to woo an Amazon headquarters, with a proposal to offer up to $500 million in local property tax breaks.

The incentive package would be spread out over 20 years, according to a copy of the 60-page bid, released Tuesday night. Inc. is on the hunt for a second corporate headquarters that would create up to 50,000 high-paying jobs and come with a $5 billion investment from the Seattle-based tech and retailing giant. Bids are due Thursday, and dozens of North American cities are expected to submit proposals, including Boston and Somerville.
