The simplified Income Tax Bill, which is half the size of the 1961 Income Tax Act, seeks to achieve tax certainty by minimising the scope of litigation and fresh interpretation, the Income Tax department said on Thursday. The new bill, introduced in the Lok Sabha, has a word count of 2.6 lakh, lower than 5.12 lakh in the I-T Act. The number of sections is 536, as against 819 effective sections in the existing law. The number of chapters has also been halved to 23 from 47, according to the FAQ issued by the I-T department.
