Which ITR Form to File in Kolkata — ITR-1, ITR-2, ITR-3, ITR-4 Explained
The most common error in ITR filing in Kolkata is selecting the wrong ITR form. This results in defective return notices from the Income Tax Department, processing delays, and refund holds. Here is a complete, plain-language breakdown of all four ITR forms and who should use each one in Kolkata.
ITR-1 for Salaried Employees in Kolkata
ITR-1 (SAHAJ) is the simplest ITR form for salaried individuals in Kolkata — including IT employees in Salt Lake Sector V, government employees, bank staff, and teachers — who have a single employer and straightforward income sources. It is the most commonly filed ITR form in Kolkata among entry-level and mid-level salaried professionals.
- Resident individual — total income up to ₹50 lakh
- Salary or pension income from one employer
- One house property income (self-occupied or let out)
- Interest income from savings accounts or FDs
- Agricultural income up to ₹5,000
- Total income above ₹50 lakh
- Capital gains from stocks, MF, or property
- More than one house property
- Foreign income or foreign assets
- Director in a company or unlisted equity shares held
ITR-2 for Capital Gains and Multiple Income Sources
ITR-2 is for individuals and HUFs who have capital gains from stocks or property, multiple house properties, ESOP income, or foreign assets — but do not have any business or professional income. This form is extremely common among Kolkata’s Salt Lake and Rajarhat IT employees who hold ESOPs, invest in mutual funds, or have inherited ancestral property generating capital gains.
- Total income above ₹50 lakh
- Capital gains — stocks, mutual funds, property sale
- More than one house property
- Foreign income, foreign bank accounts, or foreign assets
- ESOP exercise or sale gains
- Director in a company (no business income)
- Business or professional income of any kind exists
- Partner in a firm
- Presumptive income under 44AD, 44ADA, or 44AE
ITR-3 for Business Owners and Professionals in Kolkata
ITR-3 is for individuals and HUFs with income from a proprietary business or profession. This is the most commonly required ITR form for Kolkata’s doctors, lawyers, traders, jute merchants, tea brokers, chartered accountants, and entrepreneurs. It is also mandatory for F&O traders — futures and options trading is treated as business income, not capital gains, and cannot be reported in ITR-1 or ITR-2.
- Traders and business owners in Kolkata
- Doctors, lawyers, CAs, architects, consultants
- Jute traders, tea brokers, textile merchants
- Partners in a firm
- F&O traders (futures and options income)
- Anyone with business income + salary combined
- Books of accounts may be required
- Profit & loss statement needed
- Balance sheet required for larger businesses
- Tax audit mandatory if turnover exceeds ₹10 crore
ITR-4 for Presumptive Income — Small Business Owners in Kolkata
ITR-4 (SUGAM) is designed for small business owners and professionals in Kolkata who opt for presumptive taxation under Section 44AD, 44ADA, or 44AE. This simplified form allows you to declare a fixed percentage of turnover as profit — without the need to maintain detailed books of accounts. Very popular among Kolkata’s small retailers, Burrabazar traders, shop owners, and independent professionals in Gariahat and Hatibagan.
- Small business — turnover up to ₹3 crore (44AD)
- Professionals — gross receipts up to ₹75 lakh (44ADA)
- Transport operators (44AE)
- Resident individual, HUF, or firm (not LLP)
- Can also have salary or house property income
- Total income above ₹50 lakh
- Capital gains income of any kind
- Foreign assets or foreign income
- Director in a company

How to File ITR in Kolkata Online — Step by Step for FY 2025-26
ITR filing in Kolkata can be done entirely online through the Income Tax e-filing portal at incometax.gov.in. You do not need to visit any Income Tax office in Kolkata or a CA’s office. Here is the complete five-step process for FY 2025-26 (AY 2026-27).
Gather Form 16, AIS/TIS, Form 26AS, investment proofs, capital gains statements, and rent receipts. Cross-check your AIS carefully against your actual income to catch any discrepancies before you file.
This is the step where most ITR filing in Kolkata goes wrong — particularly Salt Lake IT professionals with ESOPs, MF redemptions, or F&O trades who file ITR-1 instead of ITR-2 or ITR-3. Choosing the wrong form leads to defective return notices from the Income Tax Department.
Compute total income from all sources — salary, business, capital gains, house property, interest. Apply all eligible deductions under 80C, 80D, 80G, HRA, home loan interest, NPS. Then compare the new tax regime versus the old regime to determine which saves more tax for your specific situation in Kolkata.
Login to incometax.gov.in → e-File → Income Tax Returns → File ITR. Fill in all income, deduction, and tax payment details, validate the return, and submit. Pay any remaining tax using Challan 280 before filing.
E-verify within 30 days using Aadhaar OTP, net banking, or Demat account. Without e-verification, your ITR filing in Kolkata is legally not considered complete — even if it appears submitted. This step is missed by thousands of Kolkata taxpayers every year.
New Tax Regime vs Old Tax Regime — Which is Better for Kolkata Taxpayers?
For ITR filing in Kolkata, choosing between the new and old tax regime is one of the most financially important decisions. Since Kolkata is classified as a metro city, salaried professionals paying high rent in Salt Lake, New Town, or Alipore are eligible for 50% HRA exemption under the old regime — making regime selection particularly impactful for Kolkata employees. Every ITR filing in Kolkata we handle includes a free regime comparison to ensure you pay the least tax legally possible.
| Feature | New Regime | Old Regime |
|---|---|---|
| Tax on income up to ₹7 lakh | Nil (with rebate u/s 87A) | Depends on deductions |
| Standard deduction | ₹75,000 | ₹50,000 |
| 80C deduction (₹1.5 lakh) | ❌ Not allowed | ✅ Allowed |
| HRA exemption (50% in metro Kolkata) | ❌ Not allowed | ✅ Allowed |
| Home loan interest (up to ₹2 lakh) | ❌ Not allowed | ✅ Allowed |
| 80D health insurance premium | ❌ Not allowed | ✅ Allowed |
| Best suited for | Lower deductions / simpler filing | High HRA + home loan + 80C deductions |
HRA Exemption for Rent Paid in Kolkata — How It Is Calculated
Kolkata is classified as a metro city for HRA exemption purposes — the same as Mumbai, Delhi, and Chennai. This means that during ITR filing in Kolkata, you can claim 50% of your basic salary as HRA exemption, which is significantly higher than the 40% applicable in non-metro cities. HRA is one of the most valuable deductions for salaried employees doing ITR filing in Kolkata under the old tax regime.
The HRA exemption is the minimum of these three amounts:
- Actual HRA received from employer
- 50% of basic salary (Kolkata = metro city)
- Actual rent paid minus 10% of basic salary
Important: You must have rent receipts for the full year. If annual rent exceeds ₹1 lakh, your landlord’s PAN is mandatory. HRA cannot be claimed if you are living in your own property or if you opt for the new tax regime.

Frequently Asked Questions — ITR Filing in Kolkata
Which ITR form should I file if I am an IT professional in Kolkata with ESOP income?
If you have ESOP income, you need to file ITR-2. The exercise gain (perquisite) is reported as salary income and the subsequent sale gain is reported as capital gains. ITR-1 does not have a capital gains schedule and cannot be used. ITR filing in Kolkata for ESOP cases requires careful coordination between Form 16 and the broker statement — we handle this regularly.
Can I file ITR in Kolkata without visiting any office or CA?
Yes, completely. ITR filing in Kolkata is entirely online. You can share your documents (Form 16, AIS, capital gains statements) on WhatsApp with India Service Desk and we complete your ITR filing in Kolkata remotely. No office visit, no physical signatures — the entire process is digital including e-verification.
What is the penalty for late ITR filing in Kolkata?
Filing after 31 July 2026 attracts a late fee of ₹5,000 under Section 234F (reduced to ₹1,000 if total income is below ₹5 lakh). Additionally, interest at 1% per month is charged on outstanding tax under Section 234A. Critically, capital losses cannot be carried forward if ITR is filed after the due date — this affects Kolkata stock traders and investors significantly.
I have rental income from a Kolkata property — which ITR form do I file?
If you have one house property and total income is under ₹50 lakh with no capital gains, ITR-1 may work. If you have more than one Kolkata property, income above ₹50 lakh, or any capital gains — use ITR-2. NRIs with rental income from Kolkata properties must file ITR-2 or ITR-3 depending on total income structure. Many Kolkata families have ancestral properties — income from all such properties must be reported.
How do I claim HRA exemption for rent paid in Kolkata?
HRA exemption is available only under the old tax regime. Since Kolkata is a metro city, you can claim 50% of your basic salary as HRA exemption — higher than the 40% available in non-metro cities. You need rent receipts for the full year and your landlord’s PAN if total rent exceeds ₹1 lakh per year. We calculate the exact HRA exemption correctly during your ITR filing to maximise your refund.
Do F&O traders in Kolkata need to file ITR-3?
Yes. Futures and Options (F&O) trading income is classified as business income — not capital gains. F&O traders in Kolkata must file ITR-3 regardless of profit or loss. If F&O turnover exceeds ₹10 crore, a tax audit under Section 44AB is mandatory. F&O losses can be set off against other business income and carried forward for 8 years — but only if ITR-3 is filed on time.
What is the ITR filing fee at India Service Desk for Kolkata clients?
Our fees for ITR filing in Kolkata depend on the ITR form and complexity — ITR-1 starts from ₹499, ITR-2 from ₹999 (with capital gains), and ITR-3 (business / F&O) from ₹1,499.
