CHILE is expected to raise the corporate income tax rate to 20%. The rate is 18.5% currently and had been scheduled to drop to 17% in 2013. The rate hike was part of a plan that the Chilean president presented in late April. Under the plan, the stamp duty on loans would be reduced from 0.6% to 0.2%. The 6% import duty would be phased out by 2% a year over three years starting in 2013.
