For talk of tax reform to be meaningful, members of Congress must have the courage to specify publicly which cuts to eliminate, or at least trim. As Congress moves forward on budget negotiations, the word out of Washington is to expect nothing major: no grand bargain, just more stopgap, short-term fixes. Yet there’s one ray of hope. The House and Senate chairs of the tax-writing committees, one a Republican, the other a Democrat, are preparing a comprehensive tax reform plan. They see the budget negotiations as an opportunity to enact much-needed changes to our bloated, off-kilter tax laws.
