Opportunity Zone Tax deferral valid for State

[Gaurav Mehta]

If someone invests capital gains in an Opportunity Zone in 2019, holds the property for 7 years and does improvements, they only have to pay capital gain tax on 85% of capital gains invested.

My question is does the exemption also apply for state tax component, net investment income tax and other local taxes. Or do we only get deferral and discount on the federal tax component. If yes does that mean that the remaining taxes such as state, local and net investment income tax have to be paid in the year when capital gains were realized?
