Opportunity zone
In the United States empowerment zones were introduced  in 1993  to allow local governments to compete  for grants and tax incentives. The 2017 law allows state governors to designate up to 25% of low-income census tracts in their state as opportunity zones. There are 8,700 opportunity zones  in the United States. They cover 35 million Americans. Investors in those zones can defer capital gains tax until 2026. This helps investors lower their tax burden.
