CFO Marianne Lake added on the call that "the tax rate is only one piece of the equation" when considering whether to hire more workers or raise wages.
Dimon is chairman of the Business Roundtable, a group of more than 200 chief executive officers of major U.S. companies, and has spoken strongly about the need for more business-friendly legislation in the United States.
This week, Dimon said in a commentary piece on NBC News' THINK website that American workers will be the real beneficiaries of corporate tax reform.
The piece cites estimates from accounting firm EY that showed "a competitive 20% corporate tax reduction could support the creation of as many as 2 million new jobs if the tax savings went to new job creation."
The article also pointed to an April survey from Business Roundtable that said 76 percent of 123 responding chief executive officers would increase hiring if tax reform is successful.
The GOP released a tax framework last month that proposed cutting the corporate tax rate to 20 percent from 35 percent.
However, many remain skeptical on whether tax reform will be passed soon, if at all. Congress has struggled to pass legislation on health care this year despite a Republican majority.
