Phase 1

Pre-Requisites & Document Preparation SOP

Before initiating online filing on the Income Tax e-filing portal (e-Filing 2.0), ensure all foundational tax documents and information feeds are compiled and verified.

1.1
Verify PAN-Aadhaar Linking & Portal Credentials

Confirm that your PAN is linked with Aadhaar under Section 139AA and active on incometax.gov.in. If you e-verify with Aadhaar OTP, the mobile number on the Aadhaar must be active. Net banking, a bank or demat EVC, and a signed ITR-V are separate methods.

Mandatory Check Sec 139AA e-Filing Portal
1.2
Download Form 26AS, AIS (Annual Information Statement) & TIS

Log in to the portal → Services → AIS. Download the PDF/JSON of both AIS and Taxpayer Information Summary (TIS). Simultaneously, download Form 26AS via the TRACES portal link to cross-check all TDS/TCS entries.

1.3
Compile Salary, Deductions & Banking Certificates

Collect Form 16 (Part A & Part B) from all employers for the financial year. Gather interest certificates from savings accounts, fixed deposits (Form 16A), and proof of eligible investments (Section 80C, 80D medical insurance, 80G donations, NPS u/s 80CCD(1B)).

Form 16 Part A/B Savings/FD Interest 80C/80D/80G Proofs
1.4
Consolidate Capital Gains, Crypto & Business Statements

For investors and traders, download the consolidated capital gains statement from CAMS/KFintech or stockbrokers (Zerodha, Groww, AngelOne). For freelancers and small businesses, compile gross receipts, bank credit summaries, and expenses.

Phase 2

Tax Regime Selection: Old vs New Regime (Sec 115BAC)

For the year being filed, the new regime (section 115BAC) is the default. Compare tax under both regimes on that year's figures. The comparison is a draft, and you choose before the return is filed.

Parameter New Tax Regime (Default u/s 115BAC) Old Tax Regime
Basic Exemption Limit ₹4,00,000 ₹2,50,000 (₹3,00,000 for Senior Citizens)
Standard Deduction ₹75,000 (for Salaried & Pensioners) ₹50,000
Rebate under Section 87A Rebate if taxable income is up to ₹12,00,000. With the ₹75,000 standard deduction, salary up to ₹12.75 lakh is generally within that rebate. Full tax rebate up to ₹5,00,000 taxable income
Section 80C Deductions (LIC, PPF, ELSS, Tuition Fee) Not Allowed Allowed up to ₹1,50,000
Health Insurance (Section 80D) Not Allowed Allowed (₹25,000 to ₹1,00,000)
House Rent Allowance (HRA) & LTA Not Allowed Allowed as per calculation rules
Home Loan Interest (Self-occupied u/s 24b) Not Allowed Allowed up to ₹2,00,000
Employer NPS Contribution (Sec 80CCD(2)) Allowed (up to 14% of salary) Allowed (up to 10% / 14%)
CA Decision Rule: Compare both regimes on the AY 2026–27 income tax calculator. A large HRA, 80C, 80D, or home-loan interest claim can still make the old regime lower. The calculator is an estimate; Future Tax confirms the return before filing.
Phase 3

Phase 4

Step-by-Step Online E-Filing & Tax Payment SOP

These are the usual steps on the e-filing portal (incometax.gov.in). The screen labels can change:

4.1
Log In & Navigate to File Income Tax Return

Access incometax.gov.in → Log in using PAN → Navigate to e-File → Income Tax Returns → File Income Tax Return. Select Assessment Year 2026–27 (FY 2025–26) and select mode of filing as Online.

4.2
Select Filing Status & Applicable ITR Form

Choose filing status as Individual / HUF. Select the predetermined form (ITR-1, 2, 3, or 4). Click Let’s Get Started and specify the reason for filing (e.g., Taxable income exceeds exemption limit).

4.3
Reconcile Pre-Filled Schedules with AIS/26AS

Review each schedule: Personal Information, Gross Total Income, Disclosures, and Total Deductions. Cross-check pre-filled salary, interest, and TDS amounts against your verified Form 16, AIS, and 26AS. Amend discrepancies if necessary.

4.4
Compute Tax & Pay Balance Tax via e-Pay Tax (Challan 280)

Navigate to Taxes Paid & Total Tax Liability. If there is a net tax payable, click Pay Now. Use e-Pay Tax to pay self-assessment tax (minor head 300) by net banking, UPI, or debit card. Download the challan and check the BSR code and CIN. Enter them in the return if the portal does not show them.

4.5
Run Validation & Submit Return

Click Preview Return, review the draft verification statement, and click Proceed to Validation. Fix any validation errors flagged by the portal before final submission.

Phase 5

Post-Filing SOP: E-Verification & Refund Tracking

Filing the return is incomplete without verification. If the return is not verified within 30 days, the department treats it as not filed.

5.1
E-Verification (within 30 days)

Choose a verification method on the portal:

  • Aadhaar OTP: OTP on the Aadhaar-linked mobile. This is the usual method.
  • Net Banking EVC: Log in via authorized bank net banking portal.
  • Bank Account / Demat EVC: Pre-validated bank/demat account EVC.
  • Physical ITR-V: Print, sign in blue/black ink, and speed-post to CPC Bengaluru within 30 days (do NOT courier).
5.2
Download ITR-V Acknowledgement & Computation Sheet

Once verified, download the signed ITR-V acknowledgement and detailed computation PDF from the e-Filing dashboard for your loan, visa, or audit records.

5.3
Track Processing & Intimation under Section 143(1)

Monitor your registered email for the processing intimation under section 143(1). If that intimation determines a refund, it is credited to a bank account that is pre-validated on the portal.

Late filing (Section 234F and 234A): A return filed after the due date in force can attract a late fee of ₹5,000 under Section 234F (₹1,000 if total income is up to ₹5,00,000), plus 1% per month interest on unpaid tax under Section 234A. Confirm the due date on the income-tax portal before you file.

Frequently Asked Questions — Online ITR Filing SOP

What is the mandatory deadline to e-verify an ITR after online filing?

Income tax returns must be e-verified within 30 days of submission. If the return is not verified in that time, the department treats it as not filed. File and verify again before the due date in force.

Which is better: New Tax Regime or Old Tax Regime?

For AY 2026–27 the new regime is the default. Salary gets a ₹75,000 standard deduction, and a resident with taxable income up to ₹12,00,000 gets the section 87A rebate. With that deduction, salary up to ₹12.75 lakh is generally within the rebate. The old regime still allows HRA, 80C, 80D, and home-loan interest, with a rebate up to ₹5,00,000. Compare both on the income tax calculator before you file.

What is the late fee for filing an ITR after the due date?

A return filed after the due date in force can attract a late fee of ₹5,000 under Section 234F, or ₹1,000 if total income is up to ₹5,00,000. Section 234A charges 1% per month on unpaid tax for the delay after that due date. Confirm the due date on the income-tax portal before you file.

How do I download my AIS and TIS for income tax return filing?

Log in to incometax.gov.in, navigate to the Services tab, and click on Annual Information Statement (AIS). You can download both the AIS summary and Taxpayer Information Summary (TIS) as PDF or JSON.

Can salaried employees file ITR-1 if they have capital gains from shares or mutual funds?

No. Salaried employees with capital gains from equity shares, mutual funds, or immovable property must file ITR-2 (or ITR-3 if carrying on active intraday/F&O trading).
