Quick Answer

Complete pre-filing document checklist for AY 2026-27 ITR. Lists every document you need to collect before filing, organised by income source, with reconciliation steps and a quick what-not-to-miss section for each ITR form.

The ITR filing season for AY 2026-27 has started. Most ITR notices come from incomplete or wrong information at filing time, almost always because a document was missed during preparation. Use this checklist to organise your pre-filing collection. Walk through every section that applies to your income profile.

Before You Start

  • Confirm your PAN is linked with Aadhaar. An inoperative PAN cannot file ITR.
  • Decide which tax regime you will use. New regime is the default; switching to old regime requires a conscious choice (Form 10-IEA for business income filers, ITR selection for salaried).
  • Identify the correct ITR form. ITR-1 for simple salaried with up to 2 properties; ITR-2 for capital gains and multi-property; ITR-3 for business; ITR-4 for presumptive.
  • Note the deadline applicable to you: July 31, 2026 for ITR-1/2/4 (non-audit); August 31, 2026 for ITR-3, ITR-4 (non-audit); October 31, 2026 for audit cases.

Core Documents (Every Filer Needs These)

  • PAN card (have the number ready)
  • Aadhaar card (linked with PAN)
  • Bank account details with IFSC for refund credit
  • Form 26AS downloaded from TRACES portal for AY 2026-27

  • Bank statements for all savings, current, FD, and recurring deposit accounts for FY 2025-26

Salary Income Documents

If you have salary income (employed at any point during FY 2025-26):

  • Form 16 from every employer for FY 2025-26 (issued by June 15, 2026). Note: Form 16, not Form 130; Form 130 applies from FY 2026-27 onwards.
  • Salary slips for every month, especially March 2026 (year-end bonus calculations)
  • Rent receipts and rental agreement if claiming HRA, with landlord PAN if annual rent exceeds Rs 1,00,000
  • Travel proof for LTA claims (flight or train tickets)
  • Medical bills for any reimbursement above the standard deduction
  • Form 12BB submitted to your employer for the year
  • If you changed jobs: ensure the second employer accounted for the first employer's exemptions correctly. If not, plan to recompute at filing.

  • Property address and ownership documents

  • Sale and purchase deeds for property transactions
  • Stamp duty and registration receipts (cost addition for capital gains)

  • Buy-back loss documentation if you participated in a share buy-back during FY 2025-26 (the loss is allowed only if the corresponding deemed dividend is disclosed under Income from Other Sources)
  • Schedule of foreign assets for Schedule FA (mandatory disclosure for residents)
  • Form 67 if claiming foreign tax credit

Business and Professional Income Documents (ITR-3 / ITR-4)

For proprietary business or professional income:

  • Books of accounts: cash book, ledger, journal
  • Profit and loss account for FY 2025-26
  • Balance sheet as of March 31, 2026
  • Bank statements for all business accounts
  • GST returns: GSTR-1, GSTR-3B for all months, GSTR-9 if applicable

  • PPF deposit receipt or passbook entry
  • ELSS investment statement
  • LIC and other life insurance premium receipts
  • EPF contribution shown in salary slip
  • 5-year tax-saving FD certificate
  • Tuition fee receipts (up to two children)

  • Health insurance premium for parents (Rs 25,000 / Rs 50,000 for senior parents)

  • Section 80U disability certificate

Reconciliation Steps Before Filing

Once documents are collected, perform these reconciliations in order:

  1. Form 26AS reconciliation. Match every TDS entry against your records. Total TDS in 26AS should equal sum of all Form 16 + Form 16A + Form 16B + Form 16C entries.
  2. AIS reconciliation. Walk through every category in AIS: salary, interest, dividends, mutual funds, securities, property, foreign remittance. Submit feedback for any incorrect entry.
  3. Bank interest reconciliation. Total all bank interest from passbook entries; match against AIS bank interest entry. Any gap means a missing FD or savings account.
  4. Capital gains reconciliation. Match broker P&L against AIS securities transactions. Verify cost of acquisition and date of acquisition for every entry.
  5. GST turnover reconciliation (business filers). Match GSTR-1 / GSTR-3B sales totals against your books and AIS GST turnover.

For more on reconciliation, see our AIS, Form 26AS, and TIS pre-filing guide.

ITR Form Specific Reminders

ITR-1 (Sahaj)

  • Confirm total income is up to Rs 50 lakh
  • Confirm up to 2 house properties (the limit was expanded from 1 in AY 2026-27)
  • No capital gains, no business income, no foreign assets
  • If any of the above is true, use ITR-2 or ITR-3

ITR-2

  • Confirm no business or professional income
  • Schedule CG (Capital Gains) is the largest section. Fill carefully.
  • Schedule FA (Foreign Assets) is mandatory if you hold any foreign asset, even with no foreign income
  • See our ITR-2 AY 2026-27 dedicated guide for the form-specific changes

ITR-3

  • Reconcile GSTIN-wise turnover before filing
  • The August 31, 2026 deadline (non-audit) is now permanent under the Finance Act 2026
  • See our ITR-3 AY 2026-27 guide

ITR-4 (Sugam)

  • Confirm presumptive eligibility under Section 44AD (turnover up to Rs 3 crore if 95% digital), 44ADA (gross receipts up to Rs 75 lakh), or 44AE (heavy goods vehicles)
  • Up to 2 house properties now allowed in AY 2026-27

Common What-Not-to-Miss Items

  • Joint accounts where you are the second holder. Interest is split per ownership, but check AIS to confirm reporting.
  • Closed bank accounts during the year. Get a closure statement to capture pre-closure interest.
  • Old PPF account. The interest, even if not credited to your bank, must be tracked. Withdraw passbook entry.
  • Demat dividend reinvestment. Some funds auto-reinvest; the dividend is still taxable in the year of declaration.
  • Property purchased above Rs 50 lakh during FY 2025-26. Buyer's TDS under Section 194-IA appears in your AIS as buyer; ensure the seller's TDS report matches the deed.
  • Foreign ESOPs vested but not sold. Reportable under Schedule FA and depending on tax treaty interpretation, may have a value impact.

Final Pre-Filing Checks

  • Tax regime chosen and finalised
  • All TDS entries in 26AS match your records
  • AIS feedback submitted for any incorrect entries; TIS updated
  • Pre-fill in ITR matches your records
  • Bank account active for refund credit, IFSC verified
  • Aadhaar linked with PAN
  • Self-assessment tax (if any) computed and challan generated
  • Backup of all documents stored digitally (the IT Department can ask for these any time within the next 8 years)
