Introduction
Filing an income tax return is a fundamental obligation for individuals, including non-residents, whose income exceeds the tax-exempt threshold in India. Section 139 of the Income Tax Act, 1961 (“Act”) mandates that every person (including a non-resident whose income is subject to tax in India) is required to file a return of income under Section 139 of the Act before the notified due date if the income of the person exceeds the tax- exemept threshold. Despite the legal requirement, some people fail to comply, often unaware of the significant repercussions that extend far beyond simply owing tax—penalties, legal action, and loss of financial benefits can follow. Ignoring this responsibility triggers a series of adverse outcomes, compelling taxpayers to take the process seriously to avoid complications down the line.
Consequences of Non-Filing
Failing to file an income tax return on time exposes the individual to a cascade of financial and legal consequences. First, substantial penalties apply: under Section 270A of the act, you may face a penalty for under-reporting income, calculated as the assessed income (or the difference between assessed income and the maximum amount not chargeable to tax, depending on the entity type). More serious is Section 276CC of the Act, which threatens imprisonment—ranging from six months to seven years if the tax evaded exceeds INR 25,000, and three months to two years otherwise—plus a monetary fine. Additionally, the law imposes interest on late filings: a 15% per annum charge under Section 139(8)(a) of the Act, and 1% per month (or part thereof) under Section 234A of the Act from the day after the due date until the return is filed or assessment is completed. There is also a mandatory late fee under Section 234F of the Act—INR 5,000 (INR 1,000 if total income is below INR 5 lakhs).
The tax authorities have tools to enforce compliance. If you ignore the original filing deadline, you may receive a show-cause notice under Section 142(1) of the Act, requiring you to file your return and potentially share additional information. Non-compliance with such a notice attracts further penalties: paying the tax due plus INR 10,000 for each failure under Section 271(1)(b) read with Section 271(1)(ii) of the Act, and INR 10,000 per default for non-compliance under Section 272A of the Act. If you still do not file, the Assessing Officer (AO) may proceed with a best judgment assessment under Section 144 of the Act, estimating your income and tax liability based on information available with them, which is often less favorable than a self-declared return.
Lastly, beyond direct penalties and assessments, non-filers also lose out on key benefits. Losses (under “Profits and Gains of Business or Profession” or “Capital Gains”) cannot be carried forward unless a return is filed before the due date, hindering future tax planning (as per Section 139(3) of the Act). Similarly, refunds of tax deducted at source (TDS) are only possible if you file a return (as per Section 237 of the Act read with Rule 41 of the Income Tax Rules, 1962), meaning unclaimed refunds may remain inaccessible indefinitely. These missed opportunities compound the financial impact of non-compliance.
Conclusion
Filing your income tax return is not just a statutory formality—it is a crucial aspect of financial responsibility that safeguards your interests and prevents legal jeopardy. The consequences of non-filing are severe, including stiff penalties, possible imprisonment, and the denial of carry-forward losses or TDS refunds. Proactive compliance not only avoids punitive action but also ensures you retain control over your financial and tax planning. When in doubt, consult a tax professional to meet deadlines and navigate the system efficiently, preserving your peace of mind and financial security.
