Documents You Need Before Filing
Attempting to file without complete documentation is the single most common cause of errors, mismatches, and subsequent notices. Assembling the following documents before opening the e-filing portal eliminates the need to pause mid-filing and reduces the risk of data-entry mistakes. Generate a personalized document checklist for your specific income profile using our checklist tool.
Form 16, issued by your employer by June 15, 2026, is the foundational document for salaried filers. Part A shows the TDS deducted and deposited with the government, quarter by quarter. Part B shows the detailed breakup of salary, allowances, and deductions claimed through your employer. Even with Form 16 in hand, you should cross-verify Part A against Form 26AS because discrepancies between the two are one of the most common triggers for demand notices. If your employer issued a revised Form 16 after a salary revision or arrears, use the revised version and verify TDS credit matches the latest version.
Form 26AS is your tax credit statement, available on the e-filing portal under the My Account section. It shows all TDS deducted from your income by all deductors — employer, bank, tenant, buyer — as well as any advance tax or self-assessment tax you have paid. Every entry in Form 26AS corresponds to a tax credit the government has on record for your PAN. If a deductor has deducted TDS but not deposited it, it will appear on your Form 16 but not on Form 26AS, and the credit will be disallowed. You can only claim TDS credit that appears in Form 26AS, regardless of what your Form 16 shows.
The Annual Information Statement (AIS) and the Taxpayer Information Summary (TIS) are newer documents introduced to improve pre-filling accuracy. AIS shows a comprehensive view of all financial transactions the government has information about: interest income from all banks, dividend income, securities transactions, real estate transactions, GST turnover, foreign remittances, and more. TIS is a simplified, deduplicated summary of the same information. Before filing, review your AIS carefully. If an entry appears incorrect, submit feedback directly in the AIS portal before filing. Correct AIS data flows into the pre-filled return; disputed data you have flagged will also be noted in your records.
For investment-related deductions, gather the Section 80C proof documents: Employee Provident Fund statements (EPF passbook or Form PF-11), Public Provident Fund statements, ELSS mutual fund statements, life insurance premium receipts, and National Savings Certificate records. For Section 80D, collect health insurance premium receipts for self, spouse, children, and parents. For home loan deductions under Section 24(b), obtain the interest certificate from your bank for the full financial year. For house rent allowance, ensure you have rent receipts or a rental agreement if claiming HRA exemption.
If you have capital gains income, download the capital gains statement from each broker and mutual fund house for FY 2025-26. For listed equity and equity mutual funds, the statement will show purchase and sale dates, quantity, and the gain amount pre-calculated. For debt mutual funds taxed as per income slab, ensure the statement separates short-term and long-term gains. For real estate transactions, you will need the registration documents, stamp duty receipts, and the property index value from the sub-registrar's office for cost of acquisition purposes.

Step-by-Step: Filing ITR Online
The online filing method through the e-filing portal is the recommended approach for most taxpayers because it provides pre-filled data, real-time validation, and immediate acknowledgment. The process below reflects the portal interface as of May 2026.[2]
Begin by navigating to incometax.gov.in and logging in. If you already have a registered account, enter your PAN as the user ID along with your password. If you are logging in for the first time, register using your PAN, mobile number, and date of birth. After registration, the portal sends an OTP to your registered mobile and email for verification. Once logged in, from the dashboard navigate to e-File, then Income Tax Returns, then File Income Tax Return. You will be asked to select the Assessment Year: choose 2026-27. The filing mode should be Online for the direct portal method. If you are using the offline utility, select Offline here instead and follow the JSON upload path described in the next section.
Select your taxpayer status. For most readers this will be Individual, though HUFs, firms, and companies have their own status options. After confirming Individual, the portal presents the ITR form selection screen. Based on the form selection criteria covered earlier, choose your form. For the majority of salaried taxpayers with simple income profiles, ITR-1 is displayed and pre-selected. After selecting the form, the portal asks whether you are filing originally (select Yes) and whether you want to proceed with pre-filling (select Yes). The portal then pulls pre-filled data from Form 26AS, AIS, and TIS and populates the return with income, TDS, and deduction data it already has on record.
The pre-filled return requires careful review section by section. The salary income section shows figures drawn from your employer's TDS filings with the department. Compare these with Part B of Form 16. Minor formatting differences between your Form 16 and the pre-filled data are normal; material differences in salary amounts or TDS figures require investigation before you proceed. The TDS section under Schedule TDS shows each deductor who has reported TDS against your PAN. Verify each entry against Form 26AS. Additional TDS credits not pre-filled — from banks that reported late or from deductors who filed after the pre-fill data was captured — can be added manually in the TDS schedule.
Fill the deductions section. Under Chapter VI-A, enter your Section 80C investments, Section 80D health insurance premiums, Section 80E education loan interest, Section 80G donations, and any other applicable deductions. The portal validates entries against the maximum permissible limits and warns you if an entry exceeds the ceiling. For the Old Tax Regime, deductions are the central lever for reducing taxable income; enter every eligible deduction with accurate amounts. For the New Tax Regime, Chapter VI-A deductions are largely unavailable (with a few exceptions including employer NPS contribution under Section 80CCD(2)), so the deductions section is much shorter. Plan and maximise your Section 80C deductions using our Section 80C planner tool.
After filling all income and deduction sections, reach the Tax Computation screen. This screen shows your gross total income, deductions, taxable income, tax on total income, applicable surcharge and cess, relief under Section 89 (if any), and the tax payable or refundable after accounting for TDS and advance tax already paid. If the computation shows tax payable, you must pay it before submission. Click Pay Now, which redirects you to the income tax payment portal. After payment, return to the return, enter the Challan Identification Number (CIN) in the advance tax or self-assessment tax field, and the portal will update the tax computation to reflect the payment. Once tax payable is zero (or you have a refund due), you can proceed to the submission step.
On the Preview Your Return screen, review the complete return one final time. The portal displays a summary of your income, deductions, tax paid, and refund or balance payable. Click Proceed to Validation. The portal runs automated validation checks and flags any errors or inconsistencies. Address each flagged item. Common validation errors include bank account IFSC not pre-validated, mobile number not updated in the portal, and missing Schedule AL (assets and liabilities, required for taxpayers with income above ₹50 lakh). After clearing all validation errors, click Proceed to Verification to reach the e-verification step.
Step-by-Step: Filing ITR Offline (JSON Upload)
The offline utility method is preferred by chartered accountants and taxpayers with complex returns, and is the only method available for certain forms. The CBDT releases the offline utility for each ITR form as a downloadable Java or Excel-based application. For AY 2026-27, all utilities are available at the Downloads section of incometax.gov.in.
Download the ITR utility for your form from the e-filing portal's Downloads section. At the time of writing, the utilities are available as Excel and Java formats. Run the utility and fill each section of the return using the pre-filled XML data imported from the portal or by entering data manually. The offline utility performs the same calculations as the online portal but allows you to work without an active internet connection during data entry, which matters for complex returns requiring several sessions.
Once all sections are complete, use the utility's built-in validation function. Address each validation error and warning. The utility generates a JSON file (not the older XML format used in earlier years) upon successful validation. Save this JSON file securely. Return to the e-filing portal, navigate to e-File → Income Tax Returns → File Income Tax Return, select AY 2026-27, then select the Offline mode. Upload the JSON file generated by the utility. The portal parses the JSON, displays a summary of the return, and prompts you to confirm before proceeding to the e-verification step.
The offline method has one important caveat: the JSON file is linked to your PAN and the assessment year. If you make changes to the utility after generating the JSON, regenerate the JSON and upload the fresh version. Uploading an outdated JSON that does not reflect your latest changes is a common source of errors when filers make last-minute corrections.
E-Verification: The Step Most People Forget
Filing and e-verification are two distinct steps. A submitted return is not considered filed until it is e-verified. The Income Tax Act 1961 requires e-verification within 30 days of submission. If you fail to e-verify within 30 days, the return is treated as if it was never filed — meaning penalties for late filing under Section 234F apply from the original due date, not from the submission date, regardless of when you actually submitted.[1]
The most commonly used e-verification method is Aadhaar OTP. The portal sends a six-digit OTP to the mobile number linked to your Aadhaar number. Enter the OTP within the validity window (typically ten minutes) and the verification is complete immediately. This method requires that your mobile number be seeded to Aadhaar. If your Aadhaar-linked mobile number has changed, update it at an Aadhaar enrolment centre before attempting OTP-based verification. The Aadhaar OTP method is available for returns filed both online and via JSON upload.
The Electronic Verification Code (EVC) method generates a verification code through your bank account, demat account, or ATM. Net banking EVC is available through most major banks: after completing the return on the portal, click Generate EVC through Net Banking, log in to your bank's portal, confirm the details, and receive the EVC back on the tax portal. ATM-based EVC is available at most major bank ATMs: select Generate EVC for Income Tax Return, and the ATM sends the code to your registered mobile number. Both methods are valid for returns with total income below ₹5 crore.
Digital Signature Certificate (DSC) is mandatory for companies and LLPs and optional for individuals. If you have a Class 3 DSC registered on the portal, you can e-verify by uploading your DSC during the verification step. This method is commonly used by chartered accountants filing on behalf of high-net-worth clients or business entities. Individuals without a DSC should use Aadhaar OTP or EVC.
For taxpayers who cannot complete e-verification electronically, a physical signed ITR-V (acknowledgment form) can be sent by speed post to CPC Bangalore within 30 days of filing. The ITR-V must be printed, signed in blue ink, and sent in an A4 envelope without any other documents. CPC sends an acknowledgment email upon receipt. Physical verification is slower and carries the risk of postal delays, and the CBDT has explicitly encouraged taxpayers to use electronic methods. Use physical verification only as a last resort.
Common Mistakes That Trigger Notices
The e-filing portal's automated systems cross-reference your return against a growing array of third-party data sources. Several specific errors consistently result in demand notices, scrutiny selections, or defective return notices, and most are avoidable with careful pre-filing checks.
The most common and easily avoidable error is selecting the wrong Assessment Year. Filers confuse AY 2026-27 (for FY 2025-26 income) with AY 2025-26 (for FY 2024-25 income). Filing for the wrong year does not immediately trigger a notice but creates a mismatch between your return and the TDS credits filed by your employer for the correct year, leading eventually to a demand notice. Always verify the assessment year before clicking Submit.
Income underreporting relative to Form 26AS generates the most volume of automated notices. The Compliance Management system within the CBDT cross-references every return against the full Annual Information Statement before processing the refund or finalising the assessment. Interest income from savings accounts and fixed deposits reported by banks in AIS, rental income from property registrations, mutual fund redemption proceeds reported by RTAs, and equity sale proceeds reported by brokers are all matched against your declared income. Even income amounts not required to be disclosed if below a threshold still appear in AIS, and the system flags returns where AIS entries have no corresponding disclosure. Review your full AIS before finalising the return and include all reportable income.
Omitting bank accounts is a straightforward but consequential mistake. The ITR requires disclosure of all bank accounts held during the financial year, not just the account you want your refund credited to. Every savings, current, or NRE/NRO account held in your name (or jointly, where you are the primary holder) must be listed. Accounts opened and closed during FY 2025-26 must also be disclosed. The system cross-references declared accounts against the banking KYC database. Missing accounts trigger compliance queries and, in cases where undisclosed accounts show significant credit entries, can trigger full scrutiny assessment.
Mismatched TDS credits between Form 16 and Form 26AS require resolution before filing. If your Form 16 shows TDS that does not appear in Form 26AS, do not claim that TDS credit in your return. The credit will be disallowed in processing and you will receive a demand notice for the difference. The correct approach is to contact your employer, who must file a revised TDS return to deposit and reflect the missing credit in the TRACES system. Only file your return after the Form 26AS shows the correct TDS credit for your employer's deductions. If the financial year deadline is approaching and the employer has not corrected the TDS filing, consult a chartered accountant about the options available under Section 205 of the Income Tax Act.
What Happens If You Miss the Deadline
The consequences of missing the July 31, 2026 deadline for salaried taxpayers are structured, cumulative, and in one case permanently irreversible. Understanding them precisely is important because the most damaging consequence — the mandatory New Tax Regime — cannot be undone by paying a penalty.[5]
Section 234F imposes a late-filing fee that is levied when the return is filed after the due date but before December 31, 2026. If your total income exceeds ₹5 lakh, the fee is ₹5,000. If your total income is ₹5 lakh or below, the fee is ₹1,000. The fee is charged even if your total tax liability after TDS is zero, and even if your return shows a refund due. It is charged at the time of filing the belated return; you pay it then, not in advance. The fee cannot be waived except in cases of genuine hardship through a formal application, and such waivers are rarely granted in practice.
Section 234A levies interest on any outstanding tax liability for the period after the due date. The rate is 1% per month or part month on the unpaid tax amount. If all your tax has been deducted at source and no self-assessment tax is due, Section 234A interest does not apply. If you have tax payable (common for individuals with business income, capital gains not covered by TDS, or freelance income), the interest runs from August 1, 2026 until the date you pay the outstanding tax and file the return. For a taxpayer with ₹1 lakh in unpaid tax filing three months late, this amounts to ₹3,000 in additional interest, in addition to the Section 234F fee.
The most consequential consequence of late filing is the loss of the ability to opt for the Old Tax Regime. Under the current tax framework, the right to choose the Old Tax Regime (and thereby claim deductions under Chapter VI-A) requires filing on or before the due date specified for your category. A belated return filed after July 31 under Section 139(4) is mandatorily processed under the New Tax Regime, with no Chapter VI-A deductions permitted except the very limited set available under the New Regime. For a taxpayer with significant 80C investments, home loan interest deductions, or HRA exemptions, this can mean paying substantially higher tax than would have been due if filed on time. This consequence is not a fee that can be paid — it is a permanent change to your tax computation for that year.
Beyond Section 234F, missing the due date forfeits the ability to carry forward most losses. Capital losses (other than long-term capital loss from listed equity above ₹1.25 lakh) and business losses can only be carried forward to future years if you file the original return on time. A late-filed return forfeits the carry-forward right for that year's losses. If you realised significant capital losses in FY 2025-26 that you intended to offset against future gains, filing before the due date is especially important.
Old Regime vs New Regime: Making the Choice for AY 2026-27
The Old Tax Regime versus New Tax Regime decision is the most consequential tax planning choice for AY 2026-27, and it must be made at the time of filing. For salaried taxpayers, if your employer processed salary under the New Regime throughout FY 2025-26 but you believe the Old Regime produces a lower liability, you can elect the Old Regime at filing time and claim the difference as a refund. Conversely, if you prefer the New Regime but your employer processed salary under the Old Regime, you switch at filing time and the tax differential becomes payable as self-assessment tax. Compare both regimes instantly with your exact income figures using our regime comparison tool.
The mathematical case for the Old Regime depends on the volume of eligible deductions you can claim. The standard deduction of ₹75,000 is available under both regimes and should not factor into the comparison. The deductions that create differentiation are Section 80C (maximum ₹1.5 lakh), Section 80D health insurance (up to ₹75,000 depending on age), home loan interest under Section 24(b) (up to ₹2 lakh for self-occupied property), House Rent Allowance exemption calculated under Section 10(13A), leave travel allowance, and National Pension System contributions under Section 80CCD(1B) (up to ₹50,000 above the 80C limit). A taxpayer who genuinely has these deductions and has actually invested or incurred these expenses benefits from the Old Regime. A taxpayer who has not invested in life insurance, ELSS, or PPF and does not pay rent or home loan interest typically pays less under the New Regime because its lower slab rates outweigh the deduction advantage.[2]
The New Tax Regime for AY 2026-27 applies the following rates: income up to ₹4 lakh is tax-free; ₹4–8 lakh is taxed at 5%; ₹8–12 lakh at 10%; ₹12–16 lakh at 15%; ₹16–20 lakh at 20%; ₹20–24 lakh at 25%; and income above ₹24 lakh at 30%. The New Regime also provides a full tax rebate under Section 87A for total income up to ₹12 lakh (before surcharge and cess), making the effective tax liability zero for a large segment of the middle-income salaried population. This rebate is not available if your income includes any special-rate capital gains. The Old Regime's rebate under Section 87A applies to income up to ₹5 lakh.
For taxpayers with income between ₹12 lakh and ₹20 lakh, the comparison is most sensitive to the actual deduction amounts. At this income band, the New Regime's lower rates begin to narrow the gap between the two regimes for filers with maximum 80C investments, home loans, and HRA claims. Run the actual numbers for your situation rather than relying on general rules of thumb. The break-even deduction threshold — the total deduction amount at which both regimes produce equal tax — shifts meaningfully based on your income level and the composition of your income.
Freelancers and Section 44ADA: Presumptive Taxation for Professionals
Section 44ADA is one of the most underutilised provisions in the Income Tax Act 1961, and AY 2026-27 is a good year to evaluate whether it applies to your situation. It provides presumptive taxation for specified professionals — medical practitioners, legal professionals, engineers, architects, accountants, interior decorators, technical consultants, and film artists, among others — whose gross annual receipts are below ₹75 lakh (₹37.5 lakh before AY 2020-21).[1]
Under Section 44ADA, 50% of gross professional receipts is deemed to be the net taxable income from profession. You are not required to maintain books of accounts, and you are not required to get your accounts audited. The other 50% is treated as representing all your professional expenses, including salaries, rent, travel, depreciation, and other overheads. If you actually have a higher expense ratio, you may declare a lower percentage of gross receipts as income, but only if you maintain proper books and get audited under Section 44AB. For most small professionals without significant infrastructure costs, the 50% presumptive regime is both simpler and tax-efficient.
The interaction between Section 44ADA and the regime choice is important. Presumptive income under 44ADA is treated as business or professional income, not salary income. This means the standard deduction of ₹75,000 (available to salaried individuals) is not available on 44ADA income. However, if you opt for 44ADA under the New Regime, you benefit from the lower New Regime slab rates applied to your presumptive income. If you opt for the Old Regime, you can claim deductions like 80C and 80D against the 50% presumptive income. The break-even analysis between 44ADA under Old Regime and 44ADA under New Regime follows the same logic as for salaried taxpayers, adjusted for the absence of the standard deduction.
Freelancers with gross receipts above ₹75 lakh cannot use Section 44ADA and must file ITR-3 with full books of accounts. If your gross receipts exceed ₹50 lakh, a tax audit under Section 44AB is required before filing. The new August 31, 2026 deadline for non-audit professionals filing ITR-3 is beneficial for freelancers in the ₹50 lakh to ₹75 lakh receipts range who have detailed accounting to finalise. For those below ₹75 lakh who elect the presumptive regime under 44ADA, ITR-4 is the appropriate form, with the same August 31 non-audit deadline applying. For further optimisation of deductions applicable to freelancers, our Section 80C planner covers all eligible investments and their limits in detail.
One nuance specific to AY 2026-27: the expanded ITR-4 eligibility for LTCG up to ₹1.25 lakh under Section 112A means that a freelancer who also sold listed equity mutual funds and realised long-term capital gains below this threshold can continue filing ITR-4. Previously, any capital gains income (even a small amount from a mutual fund redemption) required switching to ITR-3. This expansion materially simplifies filing for the large number of professionals who invest in mutual funds alongside their professional practice.
