How to File ITR Yourself Online in India: Step-by-Step Guide for AY 2026-27

How to File ITR Yourself

If you want the entire process in one simple roadmap, follow this order:

What Is an ITR?

ITR means Income Tax Return. It is the formal record through which you report relevant income, eligible deductions, tax already paid, and other required details to the Income Tax Department.

Depending on your circumstances, filing an ITR may be:

• legally required;
• useful for maintaining financial records;
• helpful when applying for certain loans;
• useful for visa or financial documentation;
• important for claiming a tax refund;
• necessary for reporting particular types of income.

The practical point is that ITR filing is not only about salary. Bank interest, dividends, investment sales, rent, or other income may also need attention. Start from the full set of records for the year rather than assuming Form 16 contains everything.

FY 2025-26 vs AY 2026-27

Before selecting a return, make sure you have the right year. The Financial Year tells you when the income was earned; the Assessment Year identifies the return period in which that income is reported. Choosing the wrong Assessment Year can put otherwise correct information into the wrong return.

What Is a Financial Year?

The Financial Year is the period during which you earn your income.

For this return:

FY 2025-26 = 1 April 2025 to 31 March 2026

What Is an Assessment Year?

The Assessment Year is the year in which that income is assessed and reported through the income tax return.

ITR Filing at a Glance for AY 2026-27

Before You Start: Get Your Documents Ready

Avoid starting the portal and filling numbers from memory. Gather your records first, then compare them with the information already available in the e-Filing account. That preparation makes it easier to spot a missing bank credit, an income source outside Form 16, or a mismatch that needs investigation.

Documents for Salaried Employees

Commonly useful documents include:

• Form 16;
• salary slips;
• AIS;
• TIS;
• Form 26AS;
• bank statements;
• interest certificates;
• investment records;
• home-loan documents where applicable;
• health-insurance documents where applicable;
• other deduction records.

Documents for Investors

If you sold or received income from investments, you may additionally need:

• broker statements;
• capital-gains statements;
• mutual-fund statements;
• dividend statements;
• purchase and sale information.

Documents for Rental Income

Depending on your circumstances, keep:

• rental details;
• property ownership information;
• municipal-tax information where applicable;
• home-loan information where applicable.

Which ITR Form Should You Choose?

The form is determined by the complete income profile and the applicable eligibility rules—not by job title alone. A salaried taxpayer may also have investment gains, multiple properties, or other income that changes which return is appropriate. Use the portal's current guidance and check exclusions before proceeding.

ITR-1 Eligibility: Important Beginner Check

ITR-1 may be available to an eligible resident individual with total income not exceeding ₹50 lakh when the income falls within the prescribed categories. Treat this as a starting point, not a final decision: exclusions can apply even when salary is your main source of income.

Certain capital gains, foreign assets or income, unlisted equity shares, directorship in certain companies and other specified circumstances can affect eligibility.

How to File ITR Online: Step-by-Step

Step 1: Log In to the Income Tax e-Filing Portal

Start by accessing the Income Tax e-Filing portal.

You generally need:

• PAN;
• password;
• registered mobile number;
• access to your verification method.

If you are filing for the first time, make sure your profile information is accurate.

Step 2: Select Assessment Year 2026-27

When you start the return, select the applicable Assessment Year.

For income earned during:

1 April 2025 to 31 March 2026

the corresponding Assessment Year is:

AY 2026-27

Check the year carefully before continuing.

Step 3: Select Online Filing

The Income Tax Department provides online and offline filing options for applicable ITR forms.

For a beginner following this guide, the online filing flow is generally the easiest place to start.

Select:

Online

Then continue.

Step 4: Select Your Status

The portal will ask questions that help determine your filing flow.

For an individual taxpayer, select the applicable status.

You may be asked about:

• residential status;
• income;
• filing circumstances;
• business or professional income;
• other applicable conditions.

Answer based on your actual circumstances.

Step 5: Confirm the Correct ITR Form

Use the ITR selector above as your first check.

If the portal recommends a form, review the recommendation against your actual income and circumstances.

Step 6: Review Your Personal Information

Use the pre-filled profile as a checklist, not a substitute for your own records. Confirm the identity and contact details first; an error in basic information can complicate later communication or verification.

Review:

• name;
• PAN;
• date of birth;
• address;
• mobile number;
• email;
• residential status;
• bank accounts;
• other profile information.

Step 7: Check Your Salary Income

For salaried employees, Form 16 is a key reference for salary and tax deducted at source. Compare each relevant amount with your payslips and the return rather than copying a total without checking how it is classified.

Check:

• gross salary;
• taxable salary;
• exemptions where applicable;
• deductions where applicable;
• TDS;
• employer details;
• other salary-related information.

Last year's return can help you remember categories, but it is not evidence for this year's figures. Use records for the current financial year and investigate changes in employer, salary components, or deductions.

Step 8: Review AIS

AIS stands for Annual Information Statement. It can show information reported by different entities, so it is a useful cross-check for transactions you might otherwise overlook. It is not a complete substitute for your records and a reported entry may need clarification.

Look for information relating to:

• interest;
• dividends;
• securities transactions;
• property-related transactions;
• TDS;
• other reported information.

If an entry does not match your own records, do not automatically copy or ignore it. Check the source, compare relevant dates and amounts, and follow the portal's process for feedback or correction where appropriate before finalising the return.

Step 9: Review TIS

TIS means Taxpayer Information Summary. Review it alongside AIS and your statements. A summary can help organise reported information, but it does not remove your responsibility to classify income correctly or resolve a mismatch.

Step 10: Check Form 26AS

Form 26AS is useful for checking tax credits and TDS information. Reconcile it with the related documents and your own records; if amounts differ, identify the source of the mismatch before assuming that either value is correct. This four-way check can help:

Step 11: Report Income From Other Sources

It is easy to focus on salary and overlook smaller credits. Check each bank and investment record for income that may need to be reported, even when no tax was deducted at source.

Depending on your circumstances, other income may include:

• savings-bank interest;
• fixed-deposit interest;
• recurring-deposit interest;
• dividends;
• family pension;
• certain other taxable receipts.

Example

For example, a taxpayer may have earned:

• ₹9,00,000 salary;
• ₹18,000 savings interest;
• ₹32,000 FD interest;
• ₹8,000 dividends.

The example is a reminder to review each source, not a tax computation. Whether and how each amount is taxable depends on the applicable rules and the individual's circumstances; verify the treatment before entering it.

Step 12: Report Dividend Income

If you received dividends during the financial year, reconcile the amounts across:

• dividend statements;
• broker statements;
• mutual-fund records;
• bank credits;
• AIS.

Do not automatically assume dividend income is included in salary.

Once you have reconciled the statements, report taxable dividend income in the applicable category. Do not assume that a payment appearing in a broker or mutual-fund statement has already been included in your salary information.

Step 13: Report Capital Gains

If you sold investments, capital gains may become relevant.

This can include:

• shares;
• mutual funds;
• securities;
• property;
• other capital assets.

The calculation is not simply sale proceeds minus the amount you remember paying. It may depend on:

• purchase price;
• sale price;
• purchase date;
• sale date;
• holding period;
• expenses;
• applicable tax provisions;
• exemptions or adjustments where applicable.

Step 14: Add House Property Information

If you own property, first identify how it was used during the financial year and whether there is rental income or a loan to report. Then complete the relevant house-property information using your records.

Depending on your circumstances, you may need information about:

• self-occupied property;
• let-out property;
• rental income;
• municipal taxes;
• home-loan interest;
• ownership;
• co-ownership.

Do not place rental income in an unrelated category simply because you are unsure where it belongs.

Step 15: Add Eligible Deductions

The availability and amount of a deduction depend on the applicable tax regime and the facts of your case. A payment or investment is not automatically deductible just because it appears on a statement.

Depending on eligibility, they may relate to:

• qualifying investments;
• health insurance;
• certain education loans;
• eligible donations;
• home-loan interest;
• other qualifying payments.

New Tax Regime vs Old Tax Regime for AY 2026-27

For AY 2026-27, the New Tax Regime is the default tax regime. Eligible taxpayers may choose the old regime under the applicable rules. Compare your own tax calculation under the options available to you rather than relying on a colleague's choice or on deductions you may not be able to claim.

How Should You Choose the Tax Regime?

There is no regime that is automatically best for every filer. Prepare a side-by-side calculation using the income and deductions that actually apply to you, then compare the resulting liability under each eligible option.

Consider:

• salary;
• taxable income;
• eligible deductions;
• exemptions;
• home-loan deductions;
• investment deductions;
• health-insurance deductions;
• other applicable deductions.

Then compare the resulting tax liability under each applicable regime.

Step 16: Review Tax Already Paid

The tax calculation should reflect payments and credits already recorded for you. Reconcile the return against the relevant statements instead of assuming that a pre-filled figure is complete or that every payment has already been matched.

Review applicable amounts such as:

• TDS;
• TCS;
• advance tax;
• self-assessment tax.

Make sure the tax already paid is correctly reflected against your final liability.

Step 17: Check Whether You Have Tax Payable

Once income and applicable deductions are entered, pause at the tax summary. Check whether the result is tax payable, a refund, or no further amount due, and understand the line items behind it before moving on.

You may see:

• tax payable;
• refund due;
• no additional tax payable.

If tax is payable, understand why.

Possible reasons include:

• insufficient TDS;
• additional interest income;
• dividend income;
• investment income;
• tax-regime differences;
• deductions not being available;
• other income not considered during the year.

Step 18: Check Your Refund Bank Account

If the calculation shows a refund, check that the account information is correct, active, and validated where required. A correct tax calculation does not by itself ensure that the department can credit a refund to an unusable or incorrectly entered account.

Check:

• account number;
• IFSC;
• account status;
• account ownership;
• validation status where applicable.

Step 19: Review the Entire ITR Before Submission

Do not treat the final review as a formality. Compare the return against your source documents, check the selected year and form, and confirm that each type of income has been considered. Correct mistakes before submitting rather than relying on a future notice or assuming that pre-filled data is always right.

Step 20: Submit Your ITR

Once every section has been reviewed, proceed with submission.

Before clicking the final submission button, check the summary one more time.

If something looks incorrect:

Go back → Correct it → Review again → Submit

Do not submit an incorrect return simply because you are tired of filling the form.

Step 21: e-Verify Your ITR

This is one of the most important steps in the entire process.

After filing, complete e-Verification through an available verification method.

The applicable verification window is currently 30 days from filing/uploading the return.

Common e-Verification Methods

Depending on eligibility and availability, methods can include:

• Aadhaar OTP;
• EVC through bank account;
• EVC through demat account;
• net banking;
• Digital Signature Certificate;
• ITR-V physical submission in applicable circumstances.

Aadhaar OTP is one commonly used method for eligible taxpayers.

Step 22: Save Your ITR Acknowledgement

After successful filing and verification, save your records.

Keep:

• ITR acknowledgement;
• filed ITR;
• ITR-V where applicable;
• tax payment challans;
• Form 16;
• AIS;
• TIS;
• Form 26AS;
• investment records;
• supporting documents.

Create a dedicated folder for each Assessment Year.

ITR Deadline, Late Filing Fee, Interest and Refund Timeline for AY 2026-27

Filing correctly is important, but timing matters too. If you are preparing your ITR for AY 2026-27, you should know the regular deadline, the belated-return deadline, the possible late-filing fee, interest provisions and what to expect after requesting a refund.

What Was the ITR Due Date for AY 2026-27?

For most individual taxpayers who were not required to get their accounts audited, the extended due date for filing the return for AY 2026-27 was 31 August 2026.

AY 2026-27 relates to income earned during FY 2025-26, from 1 April 2025 to 31 March 2026.

The applicable deadline can differ for taxpayers covered by audit or other special provisions, so do not assume that one date applies to every taxpayer.

Can I File ITR After the Due Date?

Yes. Missing the regular due date does not automatically mean that you can no longer file your return.

For AY 2026-27, a belated return may generally be furnished on or before 31 December 2026, or before completion of assessment, whichever is earlier, subject to the applicable provisions.

If you have missed the deadline, filing sooner is generally better than waiting until the last available date.

What Is the Late Filing Fee Under Section 234F?

If you file a belated return, a late-filing fee under Section 234F may apply.

| Total Income | Late-Filing Fee | |---|---:| | Up to ₹5 lakh | ₹1,000 | | More than ₹5 lakh | ₹5,000 |

This is a fee for delayed filing. It is separate from any income tax that may still be payable and separate from applicable interest.

Can Interest Also Apply When I File Late?

Yes. A late return can involve more than the Section 234F fee.

For AY 2026-27, the return relates to income earned during FY 2025-26, so the applicable interest provisions for that tax year are governed by the relevant provisions of the Income-tax Act, 1961.

The main provisions beginners should know are:

For applicable cases, interest under these provisions is generally calculated using the statutory monthly rates and periods prescribed under the Act. The exact amount depends on your tax liability, tax already paid and the dates involved.

What If I Already Filed and Have Tax to Pay?

If the return calculation shows tax payable, do not ignore the payment.

Before making a payment, reconcile:

• TDS;
• TCS;
• advance tax;
• self-assessment tax;
• tax already reflected in the portal;
• interest, if applicable;
• late-filing fee, if applicable.

Then pay the correct amount through the applicable e-Pay Tax process and ensure the payment is correctly reflected in your return.

How Long Does an Income Tax Refund Take?

A refund is not normally credited immediately after you click submit.

The Income Tax Department states that refund processing starts after the return is e-Verified. It also states that refunds usually take around 4–5 weeks to be credited, although the actual time can vary.

Why Can an ITR Refund Take Longer?

There is no single official “backlog number” that should be used as a blanket promise for every taxpayer.

Processing time can vary when the return requires additional checks or when information does not match the department's records.

Possible reasons include:

• TDS or tax-credit mismatch;
• incorrect tax-payment details;
• bank-account issues;
• differences between the ITR and reported information;
• additional verification;
• discrepancies requiring attention;
• other processing checks.

If your refund does not arrive within the general timeframe, check the return and refund status and look for communications or intimations from the Income Tax Department.

What Should I Do If My Refund Is Delayed?

Follow this order:

1. Check that your ITR was successfully e-Verified.
2. Check the return-processing status.
3. Check the refund status.
4. Review your registered email and portal communications.
5. Check whether there is a discrepancy or tax-credit issue.
6. Confirm that your bank account is correctly validated and suitable for receiving the refund.
7. Respond to any official communication that requires action.

Do not assume that a delayed refund automatically means your return is rejected.

What Is a Revised Return?

A revised return is generally used when you discover an error or omission in an ITR that you have already filed and the law still allows you to revise it.

Examples include:

• forgotten bank interest;
• omitted dividend income;
• incorrect income figures;
• incorrect deduction information;
• other mistakes in the originally filed return.

For AY 2026-27, the revised-return deadline has been extended to 31 March 2027, or completion of assessment, whichever is earlier, subject to the applicable provisions.

Is There an Additional Fee for a Revised Return?

Yes.

For AY 2026-27, if a revised return is filed after 31 December 2026 and up to 31 March 2027, an additional fee under Section 234I can apply.

The fee structure is:

| Total Income | Additional Revised-Return Fee | |---|---:| | Up to ₹5 lakh | ₹1,000 | | More than ₹5 lakh | ₹5,000 |

If you discover an error, it is generally better to review and correct it sooner rather than waiting for the final part of the revision window.

What Is ITR Rectification?

Rectification is different from a revised return.

A revised return is generally about correcting the return you filed.

A rectification request is generally used when an eligible mistake apparent from the record remains in a processed return or applicable order/intimation.

For example, if the processing result does not correctly reflect an eligible tax credit already available in the records, rectification may be relevant.

Revised Return vs Rectification: Which One?

| Situation | Usually Consider | |---|---| | You forgot to report bank interest | Revised Return | | You omitted dividend income | Revised Return | | You entered incorrect income information | Revised Return | | You claimed something incorrectly and revision is still available | Revised Return | | A processed return contains an eligible apparent mistake | Rectification | | A tax credit was not correctly considered in processing | Check Rectification eligibility |

Do not use rectification simply because it sounds like a quicker way to change your return. The appropriate route depends on what went wrong and whether the return has already been processed.

What About an Updated Return (ITR-U)?

An updated return is a separate mechanism from a belated return, revised return and rectification.

It has its own eligibility conditions, time limits and additional-tax consequences. It should not be treated as a routine replacement for filing a normal or revised return.

If you are considering ITR-U for AY 2026-27 or an older year, check the current eligibility rules carefully before using it.

How Long Does It Take to File ITR Yourself?

There is no single answer.

A straightforward salaried taxpayer who already has Form 16, AIS, TIS, Form 26AS and bank information may find the process manageable.

The process can take considerably longer if you have:

• multiple income sources;
• capital gains;
• multiple properties;
• business income;
• foreign income;
• complicated deductions;
• mismatched records.

The time needed depends on how complete your records are and how many income sources you have. For a straightforward salary-only case, preparation may be simple; investment sales, multiple properties, business income, or record mismatches require more careful work. The portal steps are usually not the hardest part—the judgement needed to classify and reconcile information is.

Can a Beginner File ITR Without a CA?

Yes, taxpayers with straightforward circumstances can use the online e-Filing system themselves. Self-filing does not mean relying on guesses or copying a previous return without checking whether this year's income, form eligibility, or deductions have changed. If you cannot resolve a material mismatch, seek help before submitting.

You should understand:

1. your income;
2. your tax documents;
3. your ITR form;
4. your tax regime;
5. your deductions;
6. your tax calculation;
7. your verification requirement.

When Is Self-Filing a Good Option?

Self-filing may be suitable when:

• your income is straightforward;
• you are a salaried employee;
• you have limited income sources;
• your documents are organized;
• your ITR form is clear;
• your capital gains, if any, are straightforward;
• you are comfortable checking your own return.

When Should You Consider Professional Help?

Consider professional assistance if your return involves situations where classification or eligibility is not clear, such as:

• complex business income;
• professional income;
• substantial capital gains;
• foreign income;
• foreign assets;
• complicated residential-status issues;
• multiple properties;
• complicated investment transactions;
• large carried-forward losses;
• ESOP-related matters;
• tax notices;
• scrutiny-related issues.

10 Common ITR Filing Mistakes to Avoid

What Happens After You File Your ITR?

After submission and e-Verification, your return can move through processing.

Depending on your circumstances, you may:

• receive an intimation;
• receive a refund;
• have your return processed without further action;
• receive a request for additional information;
• receive another tax communication.

Refund processing starts after e-Verification, and the Income Tax Department says refunds usually take around 4–5 weeks to be credited. That is a general indication, not a guaranteed timeline.

Keep checking your registered communication channels.

If you receive an official tax notice or communication, do not ignore it.

Can You Correct an ITR After Filing?

Yes, but the correct correction method depends on the stage of your return and the nature of the mistake.

For AY 2026-27:

• use a revised return when you need to correct your own filed return and the revision window is available;
• consider rectification when an eligible mistake apparent from the record remains after processing;
• consider ITR-U only when its separate conditions and additional-tax rules apply.

For AY 2026-27, the revised-return window generally extends up to 31 March 2027, or completion of assessment, whichever is earlier.

Should You File ITR If Your Tax Is Zero?

A zero tax liability does not automatically mean that you never need to file an ITR.

The filing requirement can depend on:

• total income;
• applicable legal conditions;
• specific transactions;
• other circumstances.

Therefore, do not use:

"My tax is zero, so I don't need to file."

as a universal rule.

Why Is ITR Filing Useful?

An Income Tax Return can provide an official record of your reported income and tax position.

Depending on the situation, your ITR records may be useful for:

• loan applications;
• visa applications;
• income documentation;
• financial planning;
• investment records;
• tax compliance;
• refund claims.

Keeping your returns organized can make future financial tasks easier.

Example: Simple ITR Filing for a Salaried Employee

Imagine a taxpayer has:

• salary income;
• savings-account interest;
• fixed-deposit interest;
• dividend income;
• no business income;
• no foreign income;
• straightforward investments.
