The CFA Society Los Angeles asks
Before 1 August 2017, will the US president sign legislation that eliminates or caps the tax exemption on municipal bond interest?
Under present federal income tax law, the interest received from municipal bonds is free from federal income taxes (The Securities Industry and Financial Markets Association). The Republican-controlled Congress has put tax reform high on the agenda and may try to eliminate or cap the tax exemptions on municipal bonds (Bloomberg, Bloomberg, The Hill).
The US president did not sign legislation eliminating or capping the tax exemption on municipal bond interest. This question closed as "b) no".
