The Central Board of Direct Taxes (CBDT) issued a draft circular clarifying that no interest under section 234A of the Income Tax Act should be charged on self-assessment tax paid before the due date for filing a tax return. Previously, interest was charged on self-assessment tax even if paid before the due date. The CBDT reviewed this after the Supreme Court ruled that interest under section 234A should only apply to tax amounts unpaid before the due date. Therefore, the CBDT decided that no interest will be charged under section 234A on self-assessment tax paid before the due date for filing a return.
