Filing an income tax return becomes much easier when all the
documents are collected before starting the return.

The difficulty is that the documents required for ITR filing
for AY 2026-27
are not the same for every taxpayer.

A salaried employee may mainly need Form 16, bank interest details
and investment proofs. A freelancer may also need professional receipt
details, expense records and GST returns. An investor may require
capital-gain statements, while a business owner may need complete books
of account and tax-audit records.

Many taxpayers begin filing with only Form 16 and later discover that
interest income, share transactions, rental income or other information
is appearing in the Annual Information Statement.

This can result in:

  • Unreported income
  • Incorrect TDS claims
  • Wrong deductions
  • Mismatch with AIS or Form 26AS
  • Selection of the wrong ITR form
  • Delay in filing
  • Income tax notices or processing adjustments

Assessment Year 2026-27 relates to income earned during Financial
Year 2025-26, covering the period from 1 April 2025 to 31 March
2026.

This income tax return checklist for 2026 explains what salaried
taxpayers, pensioners, freelancers, investors and business owners should
keep ready before filing.

Update note: This guide is updated as of 11 July
2026. The final document requirement will depend on the taxpayer’s
income, applicable ITR form and any subsequent guidance issued by the
Income Tax Department.

Want your ITR documents checked before filing?

A short document review can identify missing income, TDS mismatches and the records needed for your specific ITR form.

Review My ITR Documents

Why This Topic Matters

Income tax returns are now largely pre-filled using information
available with the Income Tax Department.

However, pre-filled data should not be accepted without checking
it.

The taxpayer remains responsible for reporting complete and correct
information, even where a transaction is missing from AIS or has been
wrongly reported by a bank, employer, broker or other reporting
entity.

The Income Tax Department specifically states that AIS contains
information presently available with the Department, but there may be
other transactions that do not appear in AIS. Taxpayers are expected to
check their records and report complete and accurate information in the
return.

Collecting the right documents helps you:

  • Select the correct ITR form
  • Report all sources of income
  • Claim the correct TDS and TCS credit
  • Calculate capital gains properly
  • Reconcile GST and business turnover
  • Claim eligible deductions
  • Compare tax regimes
  • Identify tax payable before filing
  • Preserve records in case of a future notice

A proper checklist is particularly important where the taxpayer has
more than one source of income.

For example, a salaried person may also have fixed-deposit interest,
dividends, mutual-fund gains, rental income or freelance receipts. Form
16 alone will not contain all these details.

Who Needs This Information?

This checklist is useful for:

  • Salaried employees
  • Pensioners
  • Freelancers
  • Consultants
  • Doctors, lawyers, architects and other professionals
  • Shopkeepers and traders
  • E-commerce sellers
  • Proprietorship businesses
  • Partnership-firm partners
  • Startup founders
  • Company directors
  • Investors in shares and mutual funds
  • Property owners
  • Futures and options traders
  • Cryptocurrency investors
  • Taxpayers with foreign income or foreign assets
  • MSME owners
  • Taxpayers expecting an income tax refund

The exact documents will depend on your sources of income.

You do not need every document mentioned in this article. Use the
sections that apply to your case.

Key Points You Should Know

ITR Forms Are Annexure-Less

You generally do not upload Form 16, bank statements, investment
proofs, rent receipts or other supporting documents with the income tax
return.

ITR forms are annexure-less. This means supporting documents are
generally not attached while filing the return.

However, you should preserve the records because the Income Tax
Department may ask for them during an assessment, inquiry, verification
or notice proceeding.

Form 16 Is Not
the Complete Income Tax Return

Form 16 mainly contains salary, exemptions and deductions considered
by the employer, along with salary TDS.

It may not contain:

  • Interest from all bank accounts
  • Capital gains
  • Rental income not declared to the employer
  • Freelance receipts
  • Foreign income
  • Cryptocurrency income
  • Income from another employer
  • Deductions not submitted to the employer
  • Tax paid directly by the taxpayer

You must therefore compare Form 16 with your other records.

AIS, TIS and
Form 26AS Serve Different Purposes

These three documents should be reviewed separately.

Annual Information Statement

AIS provides a wider view of financial information available with the
Income Tax Department.

It may contain:

  • TDS and TCS information
  • Salary details
  • Interest income
  • Dividend income
  • Securities transactions
  • Mutual-fund transactions
  • Property transactions
  • Foreign remittance information
  • GST-related information
  • Tax payments
  • Refund and demand information
  • Other reported financial transactions

AIS also allows taxpayers to submit feedback where reported
information is incorrect, duplicated or does not belong to them.

Taxpayer Information Summary

TIS gives a category-wise summary of information available in
AIS.

It generally provides aggregated values under income and transaction
categories. The summary may also be used for pre-filling parts of the
income tax return.

Form 26AS

Form 26AS should be checked mainly for TDS and TCS credit.

The amount claimed in the ITR should match the tax credit available
against your PAN. A difference between the amount claimed and the credit
appearing in Form 26AS can result in a tax-credit mismatch.

Pre-Filled Information
Must Be Verified

Check the following details even where they are pre-filled:

  • Name
  • PAN
  • Aadhaar details
  • Address
  • Mobile number
  • Email address
  • Bank account
  • Employer details
  • Salary
  • Interest
  • TDS and TCS
  • Advance tax
  • Self-assessment tax

The Income Tax Department advises taxpayers to verify the pre-filled
information and reconcile any discrepancy with the employer, deductor or
bank.

Documents Required

1. Basic Personal and
Filing Documents

Every taxpayer should keep the following information ready:

  • PAN
  • Aadhaar number
  • Registered mobile number
  • Registered email address
  • Current and permanent address
  • Date of birth
  • Residential-status details
  • Bank account numbers
  • IFSC codes
  • Type of bank accounts
  • Details of the bank account selected for refund
  • Previous year’s ITR acknowledgement
  • Previous tax computation, where relevant
  • Details of pending income tax notices or demands
  • Digital signature, where mandatory

Make sure that the bank account selected for refund is active and
correctly entered.

If your name, date of birth or other information is different in PAN
and Aadhaar records, resolve the mismatch before filing where
possible.

2. AIS, TIS and Form 26AS

Download the following from the income tax e-filing portal:

  • Annual Information Statement
  • Taxpayer Information Summary
  • Form 26AS

Compare these statements with your actual records.

What Should Be Checked?

Review:

  • Employer-wise salary
  • TDS on salary
  • TDS on professional receipts
  • TDS on interest
  • TCS collected
  • Bank interest
  • Dividends
  • Share transactions
  • Mutual-fund transactions
  • Property purchases and sales
  • Tax payments
  • Refunds
  • GST turnover information
  • High-value financial transactions

Do not report income only on the basis of AIS. Use AIS as a
reconciliation tool and compare it with original records.

What If AIS Is Incorrect?

Check whether the difference is because of:

  • Duplicate reporting
  • Wrong amount
  • Wrong PAN
  • Incorrect transaction type
  • Transaction belonging to another person
  • Sale value being shown instead of taxable gain
  • Correct information not yet updated

Submit suitable feedback through AIS where necessary and retain the
supporting evidence.

3. Documents Needed for
ITR-1 Filing

The following documents may be needed for an eligible taxpayer filing
ITR-1:

  • Form 16
  • Form 16A
  • Form 26AS
  • AIS and TIS
  • Salary slips
  • Bank statements
  • Bank interest certificates
  • Housing-loan interest certificate
  • Rent receipts
  • Rental agreement
  • Donation receipts
  • LIC or other eligible investment receipts
  • Dividend details
  • Details of permitted house-property income
  • Details of eligible Section 112A gains, where applicable
  • Advance-tax or self-assessment-tax challans

The Income Tax Department’s AY 2026-27 guidance lists Form 16, Form
16A, Form 26AS, AIS, payslips, bank statements, housing-loan
certificates, rent documents, donation receipts and investment records
among the relevant documents for ITR-1.

Remember that eligibility for ITR-1 should be checked separately.
Having Form 16 does not automatically mean that ITR-1 is the correct
form.

4. Form 16 for AY 2026-27

Form 16 is the salary TDS certificate issued by an employer to an
employee.

It contains information such as:

  • Employer details
  • Employee PAN
  • Salary paid
  • Exempt allowances considered
  • Deductions reported through payroll
  • Taxable salary
  • TDS deducted
  • TDS deposited

Where tax was deducted from salary during FY 2025-26, Form 16 is
required to be furnished by the employer by 15 June
2026
.

Form 16 Download for AY
2026-27

Employees normally receive Form 16 from their employer or payroll
department.

The employer, as the deductor, downloads Form 16 from TRACES and
provides it to the employee. The TRACES download process is available
through the deductor’s login, not as a normal employee download
facility.

Therefore, if you have not received Form 16:

  1. Contact your employer or former employer.
  2. Ask the payroll or HR department for both relevant parts of Form
    16.
  3. Check whether the PAN mentioned by the employer is correct.
  4. Compare the TDS with Form 26AS.
  5. Ask the employer to correct the TDS statement if the credit is
    missing or incorrect.

If You Changed Jobs During
the Year

Collect Form 16 from every employer for whom you worked during FY
2025-26.

You should also keep:

  • Joining and relieving dates
  • Salary slips
  • Full and final settlement
  • Leave encashment details
  • Gratuity details
  • Notice-pay recovery details
  • Previous-employment income declared to the new employer

Your final return must combine income from all employers.

What If No TDS Was Deducted?

Where no salary TDS was deducted, Form 16 may not be available.

In that case, keep:

  • Salary slips
  • Salary certificate
  • Bank statement
  • Employment contract
  • Full and final settlement
  • Employer-wise salary calculation

Salary income must still be reported where taxable or where return
filing is otherwise required.

5. Form 16A and Other TDS
Certificates

Form 16A is issued for TDS deducted on income other than salary.

It may be relevant for:

  • Professional fees
  • Contract payments
  • Bank interest
  • Commission
  • Rent
  • Other non-salary payments

Form 16A contains the amount credited, nature of payment, TDS
deducted and TDS deposited against the taxpayer’s PAN.

Other TDS certificates may include:

  • Form 16B for sale of immovable property
  • Form 16C for rent-related TDS
  • Form 16D for specified payments
  • Form 27D for TCS

Check each certificate against Form 26AS.

Keep:

  • Savings-account statements
  • Fixed-deposit interest certificates
  • Recurring-deposit interest details

  • Income from corporate deposits
  • Accrued interest details, where relevant
  • Interest on income tax refund
  • Loan interest received
  • Dividend statements
  • Family pension records

Do not rely only on the amount appearing in Form 16 or AIS.

Interest may be taxable even where:

  • No TDS was deducted
  • Form 15G or Form 15H was submitted
  • Interest was reinvested
  • Interest was credited to an FD rather than a savings account

  • Landlord’s PAN, where required
  • Bank proof of rent payments
  • Electricity or utility records, where relevant
  • Details of the period for which rent was paid
  • Salary slips showing HRA

Where the employer did not allow the HRA exemption, the claim may

Where a property is jointly owned, calculate income and deductions
according to the ownership share and applicable provisions.

A housing-loan interest certificate should separately show:

  • Principal repaid
  • Interest paid
  • Loan account number

Also keep:

  • Loan-sanction letter
  • Possession or completion certificate
  • Purchase deed
  • Registration documents
  • Evidence of principal repayment
  • Pre-construction interest working
  • Co-borrower and co-owner details

Do not claim the entire EMI as a deduction. Principal and interest
are considered separately and are subject to different provisions.

Funds

Keep:

  • Broker capital-gain statement

The Income Tax Department’s filing guidance states that taxpayers
with share or securities transactions should keep a summary or
profit-and-loss statement for computing capital gains.

Do not report total sale proceeds as taxable capital gains. The gain
must be calculated after considering the cost, holding period and

Book Business ITR Consultation

16. Documents
for Freelancers and Professionals

Freelancers should collect:

  • Client-wise invoices
  • Gross-receipt summary
  • Bank statements
  • Payment-gateway statements
  • Form 16A

  • Internet and telephone expenses
  • Coworking or office rent
  • Staff or subcontractor payments
  • Travel expenses
  • Professional indemnity insurance
  • Equipment purchase bills
  • Fixed-asset details

A freelancer should also determine whether income will be reported
using:

  • Actual profit after eligible expenses, or
  • A permitted presumptive taxation provision

The applicable ITR form and documentation will depend on that
decision.

17. Documents for
Presumptive Taxation

Eligible taxpayers using presumptive taxation should still maintain a
basic record of turnover and receipts.

Keep:

  • Vehicle details for applicable transport cases

The official ITR-4 guidance lists Form 16, Form 16A, Form 26AS, AIS,
bank statements, housing-loan certificates and relevant deduction
documents among the records to keep ready.

Presumptive taxation does not mean that turnover can be estimated
without supporting records.

18. Documents for
E-Commerce Sellers

E-commerce sellers may need:

  • Commission invoices
  • Shipping and logistics bills
  • Return and cancellation reports
  • Marketplace TDS details
  • Marketplace TCS details
  • GST returns
  • Inventory reports
  • Purchase invoices
  • Advertising charges
  • Warehousing charges
  • Payment-gateway reports
  • Bank statements
  • Reconciliation of gross sales with net settlements

A marketplace may deposit only the net amount after deducting
commission, advertising, shipping, TDS, TCS and returns.

For income tax purposes, turnover should generally be reconciled
using the gross transaction records rather than only the net bank
credit.

19. Foreign
Income and Foreign Asset Documents

Taxpayers with foreign income or assets may need:

  • Foreign bank statements
  • Foreign salary statements
  • Overseas employer documents
  • Foreign brokerage statements
  • Foreign shareholding details
  • Employee stock option records
  • Foreign pension or retirement account details
  • Overseas property documents
  • Foreign dividend and interest statements
  • Foreign tax deduction certificates
  • Tax residency certificate
  • Foreign tax return
  • Exchange-rate working
  • Form 67 details where foreign tax credit is claimed

Foreign reporting depends on residential status and the nature of the
asset or income.

Do not assume that foreign shares or accounts are irrelevant merely
because no income was received in India.

20. Previous Loss and
Set-Off Documents

Where losses are being carried forward or set off, keep:

  • Previous income tax returns
  • ITR acknowledgements
  • Previous computations
  • Intimations under Section 143(1)
  • Assessment orders
  • Capital-loss statements
  • Business-loss calculations
  • Speculation-loss calculations
  • House-property loss details
  • Unabsorbed depreciation details

The amount claimed should agree with the losses legally available for
set-off or carry-forward.

21. Tax Payment Documents

Keep copies of:

  • Advance-tax challans
  • Self-assessment-tax challans
  • TDS certificates
  • TCS certificates
  • Challan identification numbers
  • Payment date
  • BSR code
  • Serial number
  • Amount paid
  • Assessment year selected

For tax payments relating to FY 2025-26, the correct selection is AY
2026-27.

Check that the tax payment appears in the relevant tax records before
claiming it in the return.

Step-by-Step Process

1

Step 1: Identify Every Source of Income

Prepare a list covering:

  • Salary
  • Pension
  • Interest
  • Dividends
  • House property
  • Capital gains
  • Business
  • Professional income
  • Partnership income
  • F&O trading
  • Cryptocurrency
  • Foreign income
  • Other income

Do not start with the assumption that Form 16 contains
everything.

2

Step 2: Download AIS, TIS and Form 26AS

Download all three statements for FY 2025-26.

Review them line by line and mark each entry as:

  • Correct
  • Incorrect
  • Duplicate
  • Not belonging to you
  • Requiring clarification
  • Missing from your own records
3

Step 3: Collect Source Documents

Obtain original records from:

  • Employers
  • Banks
  • Brokers
  • Mutual-fund platforms
  • Customers
  • Tenants
  • Lenders
  • Cryptocurrency exchanges
  • Foreign institutions
  • Accounting software
  • GST portal
4

Step 4: Reconcile TDS and TCS

Compare:

  • Form 16 with Form 26AS
  • Form 16A with Form 26AS
  • Marketplace TDS with Form 26AS
  • Property TDS with the relevant certificate
  • TCS with AIS and Form 26AS

Where credit is missing, contact the deductor before filing.

5

Step 5: Reconcile Income

Compare:

  • Salary with Form 16 and bank credits
  • Interest with certificates and AIS
  • Capital gains with broker reports
  • Rent with agreements and bank receipts
  • Business sales with GST and bank records
  • Professional receipts with invoices and Form 16A
  • E-commerce turnover with platform reports
  • Foreign income with overseas statements
6

Step 6: Identify the Correct ITR Form

Form selection depends on:

  • Residential status
  • Total income
  • Business or professional income
  • Capital gains
  • Foreign assets
  • Directorship
  • Unlisted shares
  • Presumptive taxation
  • Carry-forward losses

Do not select ITR-1 merely because you receive salary.

7

Step 7: Review the Tax Regime

Check which deductions and exemptions are legally available under the
selected regime.

Keep the supporting records for each deduction actually claimed.

8

Step 8: Calculate Tax and Pay Any Balance

Common Mistakes to Avoid

Filing Only With Form 16

Form 16 does not contain every source of income.

Always check bank interest, dividends, investments, rent, capital
gains and other receipts.

Treating AIS as the Final Tax Calculation

AIS may show transaction values rather than taxable income.

For example, share-sale value is not the same as capital gain.

Ignoring TIS

TIS provides category-level summaries that may be used in
pre-filling. Compare it with AIS and actual documents.

Claiming TDS That Does Not Appear in Form 26AS

A TDS certificate alone may not result in immediate credit if the
deductor has not correctly filed or corrected the TDS return.

Forgetting Income From an Old Employer

Salary from all employers must be combined.

Using Only Net E-Commerce Settlements

Marketplace credits may be net of commission, returns, logistics
charges, TDS and TCS. Reconcile gross sales separately.

Ignoring Small Bank Accounts and FDs

Interest from every account should be checked, even where no TDS was
deducted.

Claiming Deductions Without Checking the Tax Regime

Some deductions may not be available under the selected regime.

Not Keeping Donation Details

The receipt should contain the information needed to verify the
eligible organisation and payment.

Ignoring F&O Losses

F&O activity may affect ITR form selection, turnover, audit
applicability and carry-forward of losses.

Not Reconciling GST With Income Tax Turnover

Large differences between books, GST returns, bank receipts and AIS
should be explained before filing.

Reporting Property Sale Without Cost Records

A proper capital-gain calculation may require purchase, improvement,
stamp-duty and transfer-expense documents.

Attaching Documents to the ITR

Documents are generally not uploaded with the return. They should be
retained safely instead.

How a CA Can Help

A Chartered Accountant can help organise and review documents before
preparing the return.

Professional assistance may include:

  • Preparing a personalised document checklist
  • Selecting the correct ITR form
  • Reconciling AIS, TIS and Form 26AS
  • Checking Form 16 and Form 16A
  • Combining income from multiple employers
  • Calculating capital gains
  • Reviewing house-property income
  • Examining business expenses
  • Reconciling GST turnover
  • Reviewing presumptive taxation eligibility
  • Calculating F&O turnover
  • Reviewing tax-audit applicability
  • Reporting foreign income and assets
  • Comparing tax regimes
  • Calculating self-assessment tax
  • Responding to tax mismatches or notices

The role of a CA is not merely to upload the return. The main value
lies in checking whether the income, deductions and tax credits are
supported by the available records.

When Should You Contact a CA?

Consider professional help where:

  • You have more than one Form 16
  • Your Form 16 and Form 26AS do not match
  • AIS contains incorrect or duplicate entries
  • You sold property, shares or mutual funds
  • You traded in F&O
  • You have cryptocurrency transactions
  • You are a company director
  • You are a partner in a firm
  • You have business or freelance income
  • Your GST turnover does not match your books
  • You have foreign assets or foreign income
  • You have brought-forward losses
  • You have received an income tax notice
  • You are unsure which ITR form applies
  • You are expecting a substantial refund

It is usually easier to resolve missing documents before filing than
to correct an incorrect return later.

Local Relevance for
Delhi and Delhi NCR

Taxpayers in Delhi and Delhi NCR often have income from more than one
source.

A salaried employee in Dwarka may also have rental income and
mutual-fund transactions. A freelancer in Janakpuri may receive payments
from Indian and foreign clients. A shopkeeper in Uttam Nagar may have
cash sales, UPI receipts, GST returns and business bank
transactions.

Similarly:

  • An e-commerce seller in Vikas Puri may need marketplace-wise
    settlement reconciliation.
  • A professional in Tagore Garden may have TDS deducted by several
    clients.
  • A property owner in West Delhi may need rent, municipal-tax and
    housing-loan records.
  • An investor may need broker-wise capital-gain statements.
  • An MSME owner may require GST, TDS, books and tax-audit
    reconciliation.

An income tax consultant in Delhi can help collect and organise
records digitally, while also providing in-person assistance for more
complex business or investment cases.

Rakesh Rathore and Associates provides income tax, GST, accounting,
TDS, audit and compliance support for taxpayers and business owners
in:

  • Dwarka
  • Janakpuri
  • Vikas Puri
  • Tagore Garden
  • Uttam Nagar
  • West Delhi
  • Delhi
  • Delhi NCR

Unsure which records apply to your case?

Professional review is useful for multiple Form 16s, F&O, crypto, foreign assets, tax notices or substantial refund claims.

Frequently Asked Questions

1. What are the main documents required for ITR filing for AY 2026-27?

The main documents include PAN, Aadhaar, bank details, Form 16 or
Form 16A, AIS, TIS, Form 26AS, interest certificates and records
relating to property, investments, business or capital gains.

2. Is Form 16 enough to file an income tax return?

Not always. Form 16 does not normally contain all bank interest,
capital gains, rental income, freelance receipts or foreign income. AIS,
Form 26AS and other source documents should also be checked.

3. Can an employee download Form 16 directly?

An employee normally obtains Form 16 from the employer. The employer
or deductor downloads the certificate through TRACES and issues it to
the employee.

4. What is the Form 16 issue date for AY 2026-27?

Where salary TDS was deducted during FY 2025-26, the employer was
required to furnish Form 16 by 15 June 2026.

5. What should I do if I have not received Form 16?

Contact the employer or payroll department. Meanwhile, collect salary
slips, bank statements and the full and final settlement. Also check
whether the salary TDS appears correctly in Form 26AS.

6. Do I have to attach documents with my ITR?

No. ITR forms are generally annexure-less, so supporting documents
are not attached. However, you must preserve them for future
verification or assessment.

7. What is the difference between AIS and TIS?

AIS provides transaction-level information available with the Income
Tax Department. TIS gives a category-wise summary of information
contained in AIS.

8. What if the income shown in AIS is incorrect?

Compare it with original records and submit appropriate feedback
through the AIS facility. Report the correct income in the ITR and
retain supporting documents.

9. What business documents are required for tax filing?

Business owners commonly need books of account, financial statements,
sales and purchase registers, bank statements, GST returns, expense
bills, stock records, TDS records and tax-audit documents where
applicable.

10. Are bank statements compulsory for ITR filing?

Bank statements are important for checking interest, income receipts,
expenses, tax payments and refund details. The extent of review depends
on the taxpayer’s income sources and ITR form.

11. What documents are needed for capital-gain reporting?

You may need broker statements, mutual-fund capital-gain reports,
demat statements, purchase and sale records, property deeds, improvement
bills and details of transfer expenses.

12. How long should income tax documents be preserved?

The appropriate retention period depends on the nature of the
document, applicable assessment timelines and whether any proceedings
are pending. Important records should be preserved for several years,
and longer where they relate to property cost, carried-forward losses,
foreign assets or ongoing proceedings.

Conclusion

The documents required for ITR filing for AY 2026-27
depend on the taxpayer’s complete financial position.

For a simple salaried return, the starting documents may be:

  • Form 16
  • AIS
  • TIS
  • Form 26AS
  • Bank-interest details
  • Investment and deduction records

For investors, freelancers and business owners, the checklist becomes
wider and may include:

  • Capital-gain statements
  • Professional receipts
  • Expense bills
  • GST returns
  • Books of account
  • Tax-audit records
  • Foreign income or asset details

Do not wait until the filing deadline to start collecting
records.

Early preparation gives you time to correct TDS mismatches, obtain a
missing Form 16, reconcile AIS entries and prepare capital-gain or
business-income calculations properly.
