The Big Change from Previous Years

Who Needs to File for Tax Year 2026-27?

You must file an ITR for Tax Year 2026-27 if:

Mandatory Filing Criteria

1. Income exceeds basic exemption:

   • New regime: Income > ₹4,00,000 (before standard deduction)
   • Old regime: Income > ₹2,50,000

2. Special situations regardless of income:

   • Deposited > ₹1 crore in bank current accounts
   • Spent > ₹2 lakh on foreign travel
   • Paid > ₹1 lakh electricity bill in a year
   • TDS/TCS deducted and you want a refund
   • Foreign assets or signing authority in foreign accounts

Exemption from Filing

Senior citizens (75+) with only pension and interest income from the same bank can avoid filing if their bank deducts tax correctly and they submit a declaration. This provision continues under the 2025 Act.

Choosing Your Tax Regime for Tax Year 2026-27

The most important decision in your ITR is which tax regime to choose.

New Tax Regime (Default)

You automatically fall under this if you don't make an active choice. For salaried employees, your employer deducts TDS under the new regime unless you inform them otherwise.

Slabs:

Key benefits:

• Zero tax up to ₹12,00,000 income (with rebate)
• Standard deduction of ₹75,000 for salary/pension (nil tax up to ₹12,75,000 effective)
• Employer NPS deduction (up to 14% of salary)
• No need to invest in 80C instruments

Restrictions:

• Cannot claim HRA, LTA, 80C, 80D, home loan interest (Section 24b), etc.

Old Tax Regime (Optional)

Better if you have significant deductions and exemptions.

Slabs:

Key benefits:

• Section 80C deduction up to ₹1,50,000
• Section 80D (health insurance) up to ₹25,000/₹50,000
• HRA exemption based on actual rent
• Home loan interest deduction up to ₹2 lakh
• Other Chapter VI-A deductions

When to choose old regime:

• 80C investments ≥ ₹1.5 lakh (EPF, PPF, ELSS, etc.)
• HRA exemption is significant (high-rent cities)
• Home loan with substantial interest component
• Other deductions total > ₹3.75 lakh (rough break-even point)

Step-by-Step ITR Filing for Tax Year 2026-27

Step 1: Gather Your Documents

Before you start, collect:

Income documents:

• Form 16 (from employer) — will show Tax Year 2026-27
• Form 16A (TDS certificates for other income)
• Bank passbook / statements for interest income
• Dividend statements from mutual funds / shares
• Rental agreement and rent receipts (if applicable)
• Business/professional income records

Deduction documents (if using old regime):

• PPF passbook, ELSS investment proof
• Life insurance premium receipts
• Health insurance premium receipts
• Home loan interest certificate
• Rent receipts (if HRA claim)
• Donation receipts (80G)

Other documents:

• PAN card
• Aadhaar card (linked to PAN — mandatory)
• Bank account details (for refund)
• Capital gains statement from broker / mutual fund

Step 2: Check Your AIS and Form 26AS

Annual Information Statement (AIS): Available on income tax portal. Shows all income reported against your PAN by various parties — salary, interest, dividends, mutual fund transactions, property sales, etc.

Form 26AS: Tax Credit Statement showing TDS deducted by each deductor.

Critical step: Cross-check that income in your AIS matches your actual receipts. Any discrepancy must be reconciled before filing, or you will receive a notice.

Step 3: Calculate Your Total Income

Add up all income under five heads:

1. Income from Salary (after standard deduction of ₹75,000 under new regime)
2. Income from House Property (rent minus standard deduction of 30% + municipal tax)
3. Capital Gains (STCG and LTCG, categorised by asset type)
4. Business / Professional Income (gross receipts minus allowable expenses)
5. Income from Other Sources (interest, dividends, winnings, etc.)

Example Computation (New Regime):
Gross Salary:          ₹18,00,000
Less: Standard Deduction: (₹75,000)
Salary Income:          ₹17,25,000
Interest Income:        ₹50,000
Dividend Income:        ₹30,000
Total Income:           ₹18,05,000

Tax Computation:
Up to ₹4L:             Nil
₹4L to ₹8L (₹4L × 5%): ₹20,000
₹8L to ₹12L (₹4L × 10%): ₹40,000
₹12L to ₹16L (₹4L × 15%): ₹60,000
₹16L to ₹18.05L (₹2.05L × 20%): ₹41,000
Total Tax:              ₹1,61,000
Add: 4% Cess:           ₹6,440
Net Tax:                ₹1,67,440

Step 4: Verify TDS Already Paid

From your Form 26AS, note:

• TDS deducted by your employer (Salary TDS)
• TDS on bank interest (10%)
• TDS on other income
• Advance tax paid (if any)

These are credits against your total tax liability.

Step 5: Select the Correct ITR Form

Note: Updated forms for Tax Year 2026-27 will be released by CBDT aligned with the new Act's section numbering.

Step 6: File on the Income Tax Portal

1. Log in to incometax.gov.in with PAN/Aadhaar
2. Navigate to "File Income Tax Return"
3. Select "Tax Year 2026-27" (new interface)
4. Choose ITR form
5. Select tax regime (new or old)
6. Auto-populated data from AIS will pre-fill many fields
7. Add/edit income details
8. Claim deductions (if old regime)
9. Compute tax and verify
10. Submit and e-verify (Aadhaar OTP, net banking, bank account validation)

Step 7: E-Verify Within 30 Days

After filing, you must e-verify the return within 30 days. Methods:

• Aadhaar-based OTP (fastest)
• Net banking
• Demat account validation
• Bank account EVC
• Digital Signature Certificate (DSC)

An unverified return is treated as not filed. E-verification is mandatory.

Common Mistakes to Avoid

1. Not Reconciling AIS Data

If your bank reported ₹80,000 as interest income in AIS but you claim ₹60,000, expect a notice. Reconcile first, then file.

2. Choosing Wrong Regime

The new regime is default. If you want to claim 80C/HRA/home loan deductions, you must explicitly select the old regime on the portal. Not doing so means losing all deductions.

3. Not Reporting Exempt Income

Exempt income (LTCG on equity below ₹1.25 lakh, PPF maturity, etc.) must be reported in Schedule EI (Exempt Income) even if not taxable. Failure to report raises questions.

4. Missing Capital Gains from Mutual Funds

Mutual fund platforms provide annual capital gains statements. Even small redemptions create taxable events. Missed reporting is caught via AIS.

5. Not Claiming TDS Credit

Your employer, bank, and others deduct TDS. If you don't file (or file incorrectly), you lose the refund. Even if no additional tax is due, file to claim refund of excess TDS.

6. Missing the E-Verify Step

Filing without e-verification means your return is not processed. E-verify within 30 days of filing.

Advance Tax: Are You Required to Pay?

If your tax liability (after TDS credit) exceeds ₹10,000 for Tax Year 2026-27, you must pay advance tax in installments.

Who is exempt from advance tax:

• Senior citizens (75+) with no business income
• Presumptive taxation scheme taxpayers (pay by March 15 in full)

Penalty for non-payment: Interest under Section 234B (1% per month on shortfall) and Section 234C (1% per month for each installment shortfall).

New Act-Specific Filing Features

1. Faceless Assessment (Now Default)

Under the 2025 Act, faceless assessment is the norm, not the exception. All scrutiny assessments will be conducted electronically. Physical appearance before the assessing officer is not required unless specifically ordered.

2. Dispute Resolution Panel

If you receive a draft assessment order with additional demand, you can file objections before the Dispute Resolution Panel (DRP) — especially useful for transfer pricing matters and international transactions.

3. Updated Return (ITR-U)

You can file an updated return within 2 years from the end of the Tax Year to correct mistakes, add omitted income, or claim missed deductions. For Tax Year 2026-27, the window is open until March 31, 2029.
