Here’s one thing that unites local pols across the political divide — a gentrification tax.

A bipartisan group of city lawmakers is pushing Albany to approve tweaks to the state tax laws that would allow them to hit new homebuyers with tax bills based on the actual market prices of their properties.

The coalition of 13 Republican and Democratic city council members says that taxes would not go up for existing owners.

New York’s famously opaque property tax system offers big breaks to new homebuyers by taxing them at assessed values that are often millions of dollars less than the market price.
