Income Tax Filing

Income Tax Filing in India: A Complete Guide to Returns, Assessments and Professional Support

Filing an income tax return in India is no longer the paperwork exercise it once was. The department now receives information about a taxpayer long before the taxpayer files anything — salary details from employers, interest from banks, dividends from companies, securities transactions from depositories, property transactions from registrars, high-value spends from card issuers, and every rupee of tax deducted at source, all consolidated into the Annual Information Statement. By the time a return is filed, much of it has already been pre-filled from data the department holds, and anything the taxpayer reports differently is visible immediately. This has changed the nature of the work entirely: filing is now less about compiling figures and more about reconciling them — ensuring that what the books show, what the deductors reported, what the statements reflect and what the return declares all agree. Where they do not, the mismatch surfaces automatically, usually as a communication seeking explanation, and sometimes as a full assessment proceeding conducted without any face-to-face interaction. Add to this the choice between two tax regimes, the interaction with advance tax and tax audit obligations, and limitation periods that are unforgiving once missed, and it becomes clear why income tax filing deserves professional attention rather than a last-week scramble in July.

This guide explains who must file, which form applies, the due dates and consequences of missing them, how the two regimes compare, advance tax and tax audit requirements, the notice and assessment framework, and how Delhi Legal Company supports individuals and businesses across India.

Who Must File an Income Tax Return

Mandatory filing on the basis of income. Every person whose total income before claiming specified deductions and exemptions exceeds the basic exemption limit applicable to them must file a return.

Mandatory filing irrespective of income.

  • Every company and every firm, including a limited liability partnership, must file a return regardless of income, profit or loss
  • Persons who wish to carry forward a business loss or capital loss to future years
  • Residents holding foreign assets, foreign bank accounts or beneficial interest in entities outside India, or having signing authority over foreign accounts
  • Persons meeting the prescribed high-value criteria, such as substantial deposits in bank accounts, large expenditure on foreign travel, or electricity consumption above the specified limit
  • Persons whose business turnover or professional receipts exceed the prescribed thresholds
  • Persons in whose case tax deducted or collected at source exceeds the specified amount

Voluntary filing. Filing is advisable even where it is not mandatory — to claim a refund of tax deducted at source, to build a documented income record for visa applications and loan sanctions, and to preserve the ability to carry forward losses.


Which ITR Form Applies

  • ITR-1 — resident individuals with salary, one house property, other sources and limited agricultural income, within the prescribed total income limit
  • ITR-2 — individuals and Hindu undivided families without business or professional income, including those with capital gains, multiple properties or foreign assets
  • ITR-3 — individuals and Hindu undivided families with income from business or profession
  • ITR-4 — resident individuals, Hindu undivided families and firms other than limited liability partnerships opting for presumptive taxation, within the prescribed limit
  • ITR-5 — firms, limited liability partnerships, associations of persons and bodies of individuals
  • ITR-6 — companies other than those claiming exemption for income from property held for charitable or religious purposes
  • ITR-7 — trusts, political parties, institutions and specified entities required to file under the relevant provisions

Eligibility conditions for each form are revised every year through the notified forms and schemas. Filing on the wrong form results in a defective return, which must be corrected within the time allowed or the return is treated as never having been filed.


Residential Status: The First Question

Residential status determines the scope of income taxable in India, and it is decided by physical presence tests rather than by citizenship or visa category.

  • Resident and ordinarily resident — global income is taxable in India
  • Resident but not ordinarily resident — Indian income and income from a business controlled from India are taxable; other foreign income generally is not
  • Non-resident — only income received, accruing or arising in India is taxable

Special rules apply to Indian citizens and persons of Indian origin visiting India, and to Indian citizens with high Indian income who are not liable to tax in any other country. Where income arises in more than one country, the applicable Double Taxation Avoidance Agreement, tax residency certificate and foreign tax credit provisions become relevant, along with disclosure of foreign assets in the prescribed schedules.


Old Regime and New Regime

India currently operates two personal tax regimes. The concessional regime under Section 115BAC applies as the default, with the option to be taxed under the old regime available as provided in law.

  • The old regime allows the traditional deductions and exemptions — house rent allowance, leave travel concession, housing loan interest for self-occupied property, Chapter VI-A deductions such as those for specified investments, insurance, education loan interest and donations
  • The concessional regime offers lower slab rates with most of those deductions and exemptions withdrawn, retaining only a limited set as specified

Which is better depends entirely on the individual’s actual deductions, not on general advice. Salaried taxpayers may generally choose each year; those with business or professional income face restrictions on switching once an option is exercised. Companies, firms and other entities have their own rate structures, including concessional regimes available to certain domestic and manufacturing companies subject to prescribed conditions.

Slab rates, thresholds, deduction limits and conditions are amended by the Finance Act each year. The position applicable to the relevant assessment year should always be confirmed.


The Five Heads of Income

  1. Salary — including allowances, perquisites, retirement benefits and the standard deduction as applicable
  2. House property — annual value, municipal taxes, standard deduction and interest on borrowed capital, with rules on self-occupied, let-out and deemed let-out property
  3. Profits and gains of business or profession — computed after allowable expenditure, depreciation, disallowances for non-deduction of tax at source and for cash transactions, and adjustments under the Income Computation and Disclosure Standards
  4. Capital gains — short-term and long-term, with holding periods, indexation where applicable, exemptions on reinvestment, and separate treatment for listed securities, unlisted shares, immovable property and virtual digital assets
  5. Income from other sources — interest, dividends, gifts beyond the prescribed limit, family pension, lottery and similar receipts

Clubbing provisions, set-off and carry-forward rules and deemed income provisions apply across these heads and are a frequent source of error in self-filed returns.


Advance Tax and Tax Deducted at Source

Advance tax. Where the estimated tax liability for the year, after credit for tax deducted at source, exceeds the prescribed amount, tax must be paid during the year itself in instalments on the notified dates. Shortfall and deferment attract interest under Sections 234B and 234C. Resident senior citizens without business or professional income are exempt from advance tax.

Tax deducted and collected at source. Credit is available on the basis of what deductors have reported. Before filing, the return must be reconciled against Form 26AS, the Annual Information Statement and the Tax Information Summary. Where a deductor has not filed correctly, the credit does not appear and must be pursued with the deductor — the department cannot grant credit for tax it has no record of.

Self-assessment tax. Any balance liability must be paid before filing; a return filed without payment of self-assessment tax is treated as defective.


Tax Audit and Presumptive Taxation

Tax audit under Section 44AB. Applicable where turnover or gross receipts exceed the prescribed threshold, with a higher threshold available for businesses whose cash receipts and cash payments remain within the specified proportion of total receipts and payments. A separate, lower threshold applies to professionals. Audit is also triggered where a taxpayer who had opted for presumptive taxation declares lower profits and exceeds the exemption limit. The audit report must be filed by a chartered accountant within the prescribed date, ahead of the return.

Presumptive taxation.

  • Section 44AD — eligible resident businesses within the turnover limit may declare income at the prescribed percentage of turnover, with a lower rate for digital receipts
  • Section 44ADA — eligible resident professionals within the receipts limit may declare income at the prescribed percentage of gross receipts
  • Section 44AE — transporters, on the basis of vehicles owned

Presumptive schemes reduce compliance considerably, but come with conditions — restrictions on claiming further expenditure, a lock-in on opting out, and audit consequences if lower profits are declared later.


Due Dates and the Consequences of Missing Them

Filing due dates. Non-audit cases are ordinarily due by the date notified for the assessment year; audit cases and their partners have a later date; cases requiring a transfer pricing report have a later date still. Extensions are notified from time to time and should be verified for the relevant year.

Belated return. May be filed after the due date, up to the prescribed cut-off, with late fee under Section 234F and interest under Section 234A. Business and capital losses other than house property loss cannot be carried forward in a belated return.

Revised return. A return may be revised within the prescribed period where an omission or error is discovered.

Updated return. Where filing or disclosure was missed altogether, an updated return may be filed within the extended period allowed, on payment of additional tax over and above the normal liability, with the additional amount increasing the later it is filed. Certain cases — such as returns claiming a refund or reducing liability, or where search or survey proceedings apply — are outside the scheme.

Verification. A return is not treated as filed until verified within the prescribed period, electronically or by sending the signed acknowledgement as permitted. An unverified return is invalid.


Notices, Assessments and Appeals

  • Intimation under Section 143(1) — automated processing, adjusting arithmetical errors and apparent inconsistencies, and determining refund or demand
  • Defective return notice under Section 139(9) — the defect must be cured within the time allowed, failing which the return is invalid
  • Notice under Section 142(1) — calling for information, documents or a return
  • Scrutiny notice under Section 143(2) — detailed examination of the return, conducted through the faceless assessment framework
  • Reassessment under Sections 148 and 148A — where income is alleged to have escaped assessment, preceded by the prescribed procedure and subject to specified limitation periods
  • Notices relating to tax deducted at source, high-value transactions and non-filing — often resolved by a simple reconciliation and response
  • Appeals — to the Commissioner of Income Tax (Appeals), then to the Income Tax Appellate Tribunal, with further appeal to the High Court and Supreme Court on questions of law
  • Rectification, revision and stay of demand — remedies available under the specified provisions

Responses are filed through the e-proceedings facility with limited time windows. The single most common escalation is a routine communication that went unanswered because nobody was monitoring the portal or the registered email.


Interest, Fees and Penalties

  • Section 234A — interest for late filing of the return
  • Section 234B and 234C — interest for non-payment and deferment of advance tax
  • Section 234F — late filing fee, with a lower amount for small taxpayers
  • Section 271A — penalty for failure to maintain books of account
  • Section 271B — penalty for failure to obtain or furnish the tax audit report
  • Penalty for under-reporting and misreporting of income, at differing rates depending on the nature of the default
  • Penalties under the black money legislation for non-disclosure of foreign assets, which are substantially more severe
  • Prosecution provisions in cases of wilful failure to file or wilful attempt to evade tax

Common Income Tax Filing Mistakes

  1. Filing without reconciling against Form 26AS and the Annual Information Statement, leading to automatic adjustment or a mismatch notice
  2. Using the wrong ITR form, which renders the return defective
  3. Failing to report exempt income, foreign assets or high-value transactions on the assumption that disclosure is optional
  4. Missing the previous employer’s salary for mid-year job changes, resulting in short payment of tax
  5. Claiming deductions without documentary proof capable of surviving scrutiny
  6. Choosing a regime without actually comparing the two computations
  7. Ignoring advance tax and absorbing avoidable interest under Sections 234B and 234C
  8. Filing the return but never verifying it, so it is treated as not filed at all
  9. Filing late and permanently losing the ability to carry forward business and capital losses
  10. Leaving notices unanswered because the registered email and portal were never monitored

Conclusion

Income tax compliance in India now rests on reconciliation. The department already knows most of what a taxpayer earned; the return’s function is to present that information correctly, claim what is legitimately available, and explain anything that differs. Returns filed carefully — on the right form, reconciled against departmental data, supported by documentation and verified within time — rarely create trouble. Returns assembled hastily in the final week almost always do.

Delhi Legal Company handles income tax filing alongside accounting, GST, TDS and payroll compliance, so that every filing tells the same, consistent story — and so that when a query does arrive, the answer and its supporting documents are already in place.

Frequently Asked Questions (FAQs)

1. Who is required to file an income tax return in India?

A. Every person whose total income before specified deductions and exemptions exceeds the basic exemption limit must file. Companies and firms, including limited liability partnerships, must file regardless of income or loss. Filing is also mandatory for residents holding foreign assets or signing authority over foreign accounts, for those carrying forward losses, and for persons meeting the prescribed high-value transaction criteria.

2. Should I file a return even if my income is below the exemption limit?

A. Often, yes. Filing is the only way to claim a refund of tax deducted at source, it preserves the ability to carry forward losses, and it creates a documented income record that banks, visa authorities and lenders routinely require.

3. Which ITR form should I use?

A. It depends on the nature of income and the type of taxpayer — ITR-1 and ITR-2 for individuals without business income, ITR-3 for business or professional income, ITR-4 for presumptive cases, ITR-5 for firms and limited liability partnerships, ITR-6 for companies and ITR-7 for trusts and specified institutions. Eligibility conditions change with each year’s notified forms, and using the wrong form makes the return defective.

4. What are the due dates for filing?

A. Non-audit cases have an earlier due date, audit cases and their partners a later one, and cases requiring a transfer pricing report a later date still. Extensions are notified from time to time, so the date applicable to the relevant assessment year should be confirmed rather than assumed.

5. What happens if I miss the due date?

A. A belated return may be filed up to the prescribed cut-off, with late fee under Section 234F and interest under Section 234A. Business and capital losses, other than loss from house property, cannot be carried forward. If the belated window also closes, only an updated return remains available, on payment of substantial additional tax.

6. Can a filed return be corrected?

A. Yes. A revised return may be filed within the prescribed period where an omission or wrong statement is discovered. Where the correction relates to an apparent error in processing, a rectification application is the appropriate route. Where filing was missed entirely, an updated return may be available.

7. What is an updated return?

A. It is a facility to file or correct a return after the belated and revised windows have closed, within the extended period allowed by law, on payment of additional tax over the normal liability. The additional tax increases the later the return is filed, and the facility is not available where the return would claim a refund, reduce liability, or where specified proceedings apply.

8. Should I choose the old regime or the new regime?

A. It depends entirely on the deductions and exemptions actually available to you. The concessional regime offers lower rates with most deductions withdrawn; the old regime retains them at higher rates. The only reliable method is to compute the liability under both. Salaried taxpayers may generally choose each year, while those with business income face restrictions on switching.

9. What is Form 26AS and the Annual Information Statement?

A. Form 26AS is the consolidated tax credit statement showing tax deducted, collected and paid on your behalf. The Annual Information Statement is broader, capturing reported financial transactions such as interest, dividends, securities trades, property transactions and high-value spends. Both must be reconciled before filing, since the department compares the return against them automatically.

10. What if tax was deducted but does not appear in Form 26AS?

A. Credit is granted on the basis of what the deductor has reported. If it does not appear, the deductor must correct its TDS return. Claiming credit that the department has no record of will result in an adjustment in the intimation and a demand, so the correction should be pursued before filing wherever possible.

11. What is advance tax and who must pay it?

A. Where the estimated liability for the year, after credit for tax deducted at source, exceeds the prescribed amount, tax must be paid during the year in instalments on notified dates. Shortfall or deferment attracts interest under Sections 234B and 234C. Resident senior citizens without business or professional income are exempt.

12. When is a tax audit required?

A. Where turnover or gross receipts exceed the prescribed threshold, with a higher threshold available where cash receipts and cash payments stay within the specified proportion of the total. Professionals have a separate, lower threshold. Audit is also triggered where a taxpayer previously under a presumptive scheme declares lower profits and exceeds the exemption limit.

13. What is presumptive taxation and should I opt for it?

A. Presumptive schemes allow eligible businesses, professionals and transporters within prescribed limits to declare income at a specified percentage of turnover or receipts, with substantially reduced compliance. The trade-offs are real — further expenditure generally cannot be claimed, opting out carries a lock-in period, and declaring lower profits later triggers audit. It suits businesses with genuinely high margins and modest record-keeping.

14. Is filing complete once the return is submitted?

A. No. A return must be verified within the prescribed period, electronically or by the permitted physical route. An unverified return is treated as never having been filed, which is one of the more common and entirely avoidable failures.

15. How long do refunds take?

A. Refunds are issued after processing under Section 143(1), and generally arrive within weeks where the return is straightforward and reconciles with departmental data. Delays typically arise from mismatches, unvalidated bank accounts, or adjustment of the refund against an outstanding demand from an earlier year.

16. I have received a notice from the income tax department. What should I do?

A. Identify the section under which it has been issued and the response deadline, reconcile the underlying data, and file a complete, documented response through the e-proceedings facility within time. Many notices are routine mismatches that close on proper explanation. The same notice ignored becomes an assessment order with tax, interest and penalty.

17. What is faceless assessment?

A. Assessment and appellate proceedings are largely conducted electronically, without physical interface with a specific officer. Notices and responses are exchanged through the portal, which makes timely monitoring of the registered email and portal account essential — there is no officer who will telephone a reminder.

18. How is income of non-residents taxed in India?

A. Non-residents are taxed on income received, accruing or arising in India. Treaty benefits may reduce or eliminate Indian tax on specified income, subject to a tax residency certificate, Form 10F and the beneficial ownership requirements. Residential status must be determined first, as it governs the entire scope of taxation.

19. Do I have to disclose foreign assets and foreign income?

A. Residents and ordinarily residents must disclose foreign assets, foreign bank accounts, foreign income and beneficial interests in the prescribed schedules, regardless of whether income arose from them. Non-disclosure carries consequences under the black money legislation that are considerably more severe than ordinary income tax penalties.

20. How are capital gains on shares, mutual funds and property taxed?

A. Treatment depends on the asset class and holding period, with different rules for listed securities, unlisted shares, immovable property and virtual digital assets, and separate provisions governing indexation and reinvestment exemptions. Because the rules have been amended in recent years, the position applicable to the date of transfer should be confirmed before computing.

21. How long should tax records be preserved?

A. Generally six years from the end of the relevant assessment year, and longer where reassessment, appeal or other proceedings are pending or possible. Records supporting the cost of long-held assets should be kept until well after those assets are sold.

22. Can you handle filing along with our GST, TDS and accounting work?

A. Yes, and it materially reduces risk. When the same team maintains the books and files GST, TDS and income tax returns, turnover, credits and disclosures reconcile across filings — which is precisely what the department’s data-matching systems check.

23. Can you review our earlier returns and assessments?

A. Yes. A review of past filings can identify unclaimed deductions, credits not availed, errors capable of rectification and exposures worth addressing voluntarily — provided the applicable limitation periods are still open.

24. How do I get started?

A. Write to info@delhilegalcompany.com or call +91-9599332456. We will review your income sources, filing history and any pending notices, and share a clear scope and quotation before any work begins.
