On June 15, 2017, the New York City Campaign Finance Board approved rules to be effective on July 23, 2017.

Under the new rules, a candidate does not have to inquire whether a contributor is doing business with the city and prohibits matching public funds for contributions intermediated by individuals doing business with the city.
