The administration may line up several options before deciding whether to follow through on the first stage of consumption tax hikes next April, sources said Saturday.
Some of the options would change the timing or size of the increase, they said.
They will likely include the idea of gradually raising the 5 percent tax rate by 1 point a year, versus the shift to 8 percent in April and 10 percent in October 2015 as spelled out by the law enacted in August 2012.
