Deduction for Special Economic Zone unit profits permitted, calculated per section 10AA and limited to eligible tax years. The Bill permits a deduction in computing total income for an assessee who begins manufacturing or providing services referred to in section 10AA and would have been eligible for export-related deductions under the repealed income-tax provision. The deduction must be calculated as per the provisions of section 10AA and is allowed only for those tax years that would have been permitted under section 10AA if that Act had not been repealed.
