ITR Filing in India — Complete Guide for Salaried, Self-Employed, and Investors

Income Tax Return (ITR) filing is the annual process of declaring income, deductions, and tax paid to the Income Tax Department. Filing is mandatory if annual income exceeds ₹2.5 lakh (regardless of regime) or other specific conditions (foreign assets, capital gains, business income, TDS deducted, etc.). The right ITR form depends on income sources: ITR-1 (Sahaj) for salaried only with simple income (no capital gains, no foreign assets); ITR-2 for salaried with capital gains, foreign assets, or multiple income sources; ITR-3 for those with business or professional income; ITR-4 (Sugam) for presumptive income business. Due date: July 31 for most individuals; December 31 for those with audit requirement; October 31 for businesses with audit. Late filing penalty: ₹1,000 if income under ₹5 lakh; ₹5,000 if above ₹5 lakh; interest of 1%/month on unpaid tax. Filing online (incometax.gov.in) is free; professional CA help costs ₹1,500-10,000 depending on complexity. Freedomwise's Old vs New Tax Regime covers the regime decision; this article covers the filing process.

Which ITR form should I use?

Form selection based on income type:

ITR Form	Best for	Key conditions
ITR-1 (Sahaj)	Salaried with simple income	Income ≤₹50 lakh; salary + house property + other sources; no capital gains; no foreign assets
ITR-2	Salaried + investors	Capital gains; foreign assets; multiple house properties; no business income
ITR-3	Business/professional	Business or professional income; partner in firm
ITR-4 (Sugam)	Presumptive business	Presumptive scheme under 44AD/44ADA/44AE; income ≤₹50 lakh
ITR-5	Firms, LLPs	Partnership firms, LLPs (not for individuals)
ITR-6	Companies	Companies (not for individuals)
ITR-7	Trusts, NGOs	Specific entities (not for individuals)

Most common for individuals: ITR-1 (simple salaried) or ITR-2 (salaried + investments). Many investors mistakenly file ITR-1 when they should file ITR-2 — triggering compliance issues.

When does ITR-1 not work?

ITR-1 cannot be used if you have any of:

• Capital gains (from equity, MF, property, gold sales)
• Foreign assets or foreign income
• Income from more than one house property
• Income exceeding ₹50 lakh
• Director in a company
• Investments in unlisted equity shares
• Agricultural income exceeding ₹5,000
• Cryptocurrency transactions

If any apply, switch to ITR-2. Filing ITR-1 incorrectly can trigger notices and amendments. Use the official "Help me choose ITR" tool on income tax portal if uncertain.

What documents do I need to file ITR?

Essential documents:

Income proofs:

• Form 16 from employer (salary income)
• Form 16A from banks (FD interest TDS)
• Form 26AS (complete TDS statement — must reconcile with employer/bank)
• AIS/TIS (Annual Information Statement, Taxpayer Information Statement — comprehensive view of reported income)
• Capital gains statements from brokers/AMCs

Deduction proofs (if old regime):

• Section 80C: PPF receipts, EPF statement, ELSS purchase, life insurance premiums, home loan principal paid, tuition fees
• Section 80D: Health insurance premiums
• Section 24: Home loan interest certificate
• Section 80E: Education loan interest
• HRA: Rent receipts, rental agreement
• LTA: Travel bills (specific journeys)

Bank details:

• All bank accounts for the year
• Bank statements (interest income tracking)
• PAN, Aadhaar (mandatory linking)

Investment proofs:

• Demat statements
• Mutual fund consolidated statements
• Foreign asset details (if applicable, for Schedule FA)

What is the difference between Form 26AS and AIS?

Form	What it shows	When introduced
Form 26AS	Tax credits (TDS, TCS, advance tax, refunds)	Long-established
AIS (Annual Information Statement)	Comprehensive income view from multiple sources	Newer (2021+)
TIS (Taxpayer Information Summary)	Aggregated/summary version of AIS	Newer

AIS captures: salary, interest income from banks, mutual fund redemptions, equity/F&O transactions, foreign remittances, property purchases, etc. — reported by various entities.

Critical compliance: Your ITR should match the AIS. Discrepancies trigger notices. Always reconcile before filing.

What is the step-by-step ITR filing process?

Online filing on incometax.gov.in:

1. Register/login with PAN (and Aadhaar verification)
2. Choose ITR form (use Help-me-choose tool if uncertain)
3. Pre-fill — most data auto-populated from AIS and Form 26AS
4. Verify pre-filled income against your records
5. Add deductions (if old regime) — 80C, 80D, etc.
6. Compute tax liability — system calculates automatically
7. Pay balance tax (if any) before submission
8. Submit ITR — generates Acknowledgement (ITR-V)
9. E-verify within 30 days — via Aadhaar OTP, net banking, EVC, or send signed ITR-V by post
10. Get refund (if applicable) — usually within 1-3 months for accurate returns

The entire process can be completed in 1-3 hours for straightforward returns.

What if I miss the July 31 deadline?

Late filing consequences:

• Belated return allowed until December 31 of assessment year (FY 2026-27 belated until Dec 31, 2027)
• Penalty: ₹1,000 if income ≤₹5 lakh; ₹5,000 if above
• Interest: 1% per month on unpaid tax under Section 234A
• Loss carry-forward disallowed: Capital losses, business losses cannot be carried forward if filed late
• Refund delay: Late filed returns processed slowly
• Tax demand notice: If discrepancies found, no time for revision

After December 31, the option becomes updated return under Section 139(8A) — allowed for 2 years but with additional tax (25-50% extra). File on time to avoid these costs.

When should I consult a CA vs DIY filing?

DIY is appropriate for:

• Single-employer salaried with standard deductions
• Simple ITR-1 or ITR-2 with clear documentation
• No complex situations (foreign assets, business income, multiple properties)
• Confident with online forms

CA is valuable for:

• First-time investors with capital gains
• Foreign asset holders (Schedule FA complexity)
• Business or professional income
• Multiple property owners
• High net worth with complex transactions
• ITR notices or scrutiny

Cost guidance:

• DIY: free
• Basic CA assistance (ITR-1/2): ₹1,500-5,000
• Complex returns (ITR-3, foreign assets): ₹5,000-25,000
• Tax planning consultation: ₹10,000-50,000

Many investors benefit from CA help for first year, then DIY in subsequent years using prior return as template.
