Full Legal Analysis
Self Assessment is the process by which a taxpayer computes their own total income and corresponding tax liability, adjusts for any TDS, TCS, and Advance Tax already paid, and pays the balance remaining tax before filing their final Income Tax Return.
The concept forms the bedrock of modern Indian tax administration, which relies heavily on voluntary compliance. Most returns filed under self-assessment are accepted 'as is' through automated processing, with only a small percentage selected for Scrutiny Assessment.
Payment of self-assessment tax is a mandatory prerequisite for filing a valid return. If a return is filed without paying the full self-assessment tax due, the return may be deemed a 'defective return' under Section 139(9).
The Supreme Court held that if an assessment fails or is struck down, the taxpayer cannot claim a refund of the self-assessment tax they voluntarily calculated and paid, as it represents their admitted liability.
Advocates must ensure clients pay all self-assessment tax and accrued interest (under Sections 234A/B/C) before filing the return to avoid subsequent penalty notices and the invalidation of the return.
