ITR Filing Deadline 2026: The countdown has begun for Income Tax Return (ITR) filing for FY 2025-26 (AY 2026-27). General taxpayers now have just three days left to submit their returns before the July 31, 2026 deadline.

Missing the due date could cost you a late fee of up to ₹5,000, along with possible interest and additional compliance issues.

👉 Business taxpayers filing ITR-3 and ITR-4 have time until August 31, 2026.

Even if you miss the July 31 deadline, you can still file a Belated ITR until December 31, 2026, but only after paying the applicable late fee.

Your Income Tax Return (ITR) is more than just a tax document—it serves as your official proof of income and financial history, making it important for loan approvals, visa applications, and future financial transactions.

🤖 Income Tax Department Uses AI to Detect Errors

The Income Tax Department now uses Artificial Intelligence (AI), data analytics, PAN-based tracking, AIS, TIS, Form 26AS, banking data, mutual fund records, property transactions, and even foreign travel information to verify the accuracy of your ITR.

Any mismatch between your return and government records can trigger:

• ⚠️ Tax notices
• 💰 Additional tax demand
• 📈 Interest charges
• 🚫 Penalties

To help taxpayers avoid costly mistakes, Indore-based Chartered Accountant Anand Jain shares 10 important points everyone should keep in mind before filing an ITR.

✅ 1. Don’t Depend Only on Form 16

Many salaried employees assume Form 16 contains everything required for filing ITR.

That’s not true.

Form 16 only reports:

• Salary income
• TDS deducted by your employer

You must also disclose income from:

• 💵 Fixed Deposits (FD)
• 💳 Recurring Deposits (RD)
• 🏦 Savings Account Interest
• 📈 Dividends
• 🏠 Rental Income
• 💻 Freelancing
• 📊 Share Market
• 💹 Mutual Funds
• 🌍 Foreign Income

Failing to report these incomes can result in additional tax and interest later.

✅ 2. Choose the Correct ITR Form

Selecting the wrong ITR form can make your return defective, meaning it may be treated as not filed at all.

Which ITR Form Should You Choose?

ITR-1 (Sahaj)

✔ Salary

✔ Pension

✔ Interest Income

ITR-2

✔ Capital Gains

✔ More than one house property

✔ Foreign assets or income

ITR-3

✔ Business income

✔ Freelancing

✔ F&O Trading

✔ Stock Trading

ITR-4 (Sugam)

✔ Small businesses

✔ Professionals under presumptive taxation

✅ 3. Verify AIS, TIS and Form 26AS Before Filing

Before submitting your return, compare your income details with:

• 📄 Form 16
• 📄 Form 26AS
• 📄 AIS (Annual Information Statement)
• 📄 TIS (Taxpayer Information Summary)

If you notice incorrect information, raise a grievance through the Income Tax portal before filing.

✅ 4. Changed Jobs? Combine Salary From Both Employers

If you switched jobs during FY 2025-26, remember to include salary received from both employers.

Ignoring one employer’s salary may result in:

• Higher tax liability
• Lower TDS credit
• Income Tax notice

✅ 5. Double-Check Your Bank Account Details

Ensure all active bank accounts are correctly reported.

Before submitting your ITR, verify:

✔ Account Number

✔ IFSC Code

✔ Refund Bank Account

Incorrect bank details can delay your income tax refund.

✅ 6. Never Hide Interest Income

Many taxpayers believe that if no TDS is deducted, the income isn’t taxable.

This is completely incorrect.

The Income Tax Department already receives information regarding:

• FD Interest
• RD Interest
• Savings Account Interest
• Bond Interest

through banks and AIS.

Failure to disclose this income can invite penalties.

✅ 7. Report Share, Mutual Fund and Property Transactions

Every transaction linked to your PAN is reported to the Income Tax Department.

Declare:

• 📈 Share Market Profit/Loss
• 💹 Mutual Fund Redemption
• 🏠 Property Sale

Even if you incurred a loss, report it because capital losses can be carried forward to reduce future tax liability.

✅ 8. Claim Only Genuine Tax Deductions

Claim deductions only if you actually qualify and have supporting documents.

Popular deductions include:

• 💰 Section 80C
• 🏦 National Pension System (NPS)
• 🩺 Section 80D (Health Insurance)
• 🏠 Home Loan Interest

Keep all supporting documents safely for future verification.

✅ 9. Disclose Foreign Assets and Overseas Income

If you own:

• Foreign Shares
• International ETFs
• Overseas Bank Accounts
• Foreign Investments

you may be required to disclose them, especially if you are a Resident and Ordinarily Resident (ROR) under Indian tax laws.

Failure to disclose foreign assets may attract serious penalties.

✅ 10. Don’t Forget E-Verification

Submitting your ITR is only the first step.

You must complete e-verification, otherwise your return will be treated as invalid.

You can verify your return through:

• 📱 Aadhaar OTP
• 🏦 Net Banking
• 📈 Demat Account
• 🔐 Digital Signature Certificate (DSC)

Complete verification within the prescribed time limit.

💰 Late Fee After July 31: Here’s How Much You’ll Pay

If you file your Income Tax Return after July 31, 2026, you’ll need to pay a late filing fee under the Income-tax Act.

In addition to the late fee, delayed filing may also result in interest on unpaid taxes and certain restrictions on carrying forward eligible losses.
