The Tax Commission on Friday unveiled three provisional tax hike proposals centered on increasing income and corporate taxes to secure funds for reconstruction from the March 11 disasters.

The government's three proposals are: to increase income, corporate and residential taxes; to hike the income, corporate and tobacco taxes; or to raise only the consumption tax. The measures would likely stay in place for around 10 years.

The government plans to slash the corporate tax by 5 points so any corporate tax hike would likely offset that reduction.
