Form 26AS, AIS and TIS: The Three Documents Every ITR Filer Must Reconcile in 2026

Why Reconciliation Matters More Than Ever

For AY 2026-27 filings, the Central Board of Direct Taxes (CBDT) continues to auto-populate most fields in your ITR — salary, interest income, capital gains, dividends, TDS, foreign remittances and even high-value transactions. The data flows from three overlapping statements: Form 26AS, the Annual Information Statement (AIS), and the Taxpayer Information Summary (TIS).

If the numbers in your ITR don't match what the department already has, you can expect an intimation under Section 143(1) within weeks, and in some cases a scrutiny notice under Section 143(2). Reconciliation is no longer optional — it is the foundation of a clean return.

What Each Document Actually Contains

Form 26AS is the oldest of the three. It captures:

• •TDS deducted by employers, banks, tenants and others
• •TCS collected (e.g., on foreign travel, luxury goods)
• •Advance tax and self-assessment tax paid by you
• •Refunds issued
• •Details of specified financial transactions (SFT) reported by banks and registrars

AIS (Annual Information Statement) is broader. Beyond 26AS data, it captures:

• •Savings account interest (even where no TDS was deducted)
• •Dividend income from every listed company
• •Purchase and sale of listed securities and mutual funds
• •Rent received (from tenant TDS filings)
• •Foreign remittances under LRS
• •Credit card spends above threshold
• •Property purchase/sale reported by the registrar

TIS (Taxpayer Information Summary) is a category-wise aggregated view of AIS — it shows the "processed value" the department will use unless you dispute it.

Comparison at a Glance

## The Reconciliation Workflow

Follow this sequence before hitting "Submit" on your ITR:

Step 1: Download all three statements. Log in to incometax.gov.in, go to Services → Annual Information Statement. Download AIS and TIS as PDFs (password is PAN in lowercase + date of birth in DDMMYYYY). Download 26AS from the e-filing portal under "View Form 26AS".

Step 2: Match TDS entries between 26AS and Form 16/16A. Every deductor's TAN, section (192, 194A, 194-IB, etc.) and amount must tally. Missing entries usually mean the deductor filed a late or incorrect TDS return — chase them before filing.

Step 3: Verify AIS income entries against your bank statements and broker reports. Common mismatches:

• •Bank interest reported gross while you remember only the net credit
• •Mutual fund redemptions showing as "sale of securities" — check whether cost basis and holding period are correctly captured
• •Dividends double-counted because registrar and company both report

Step 4: Submit feedback for errors. Inside AIS, each transaction has a "Provide Feedback" button. Options include "Information is correct", "Information is not fully correct", "Information relates to other PAN", "Information is duplicate", and "Information is denied". Submit feedback with supporting evidence.

Step 5: Re-download TIS after 48 hours — accepted feedback updates the processed value, which then flows to your pre-filled ITR.

Real-World Mismatch Examples

Case 1 — Salary + moonlighting: Anita earns ₹18 lakh salary and ₹2 lakh from freelance work. Her AIS shows both, but her employer's Form 16 shows only salary. Filing only Form 16 income triggers an under-reporting flag. Correct action: report freelance income under "Income from Business/Profession" or apply Section 44ADA if eligible.

Case 2 — Joint bank account: Interest of ₹40,000 in a joint FD gets reported in the AIS of both holders. If both report full amount, department sees double-counting. Correct action: one holder reports full income; the other submits AIS feedback marking "Information relates to other PAN".

Case 3 — Mutual fund switch: A switch from regular to direct plan is reported as a "sale" in AIS with full redemption value. The taxpayer thinks nothing was sold. Correct action: report the switch as a capital gains transaction — because for tax law, a switch is a redemption plus a fresh purchase.

Case 4 — Property sale advance: Buyer deducts TDS under Section 194-IA at 1% on advance payment in March; sale deed executes in April. TDS appears in FY 2025-26 26AS but capital gain accrues in FY 2026-27. Correct action: claim TDS in the year of accrual as per Rule 37BA, with proper disclosure.

Consequences of Ignoring Mismatches

• •Section 143(1) intimation: Automatic adjustment of tax liability based on department data, often with additional demand and interest under Sections 234A/B/C.
• •Section 270A penalty: 50% of tax on under-reported income, 200% if deemed misreporting.
• •Section 148 reopening: For high-value mismatches, assessments can be reopened up to 5 years later (or 10 years for income above ₹50 lakh).
• •Refund delays: Even genuine refunds get held up when the system detects unexplained gaps.

Special Points for FY 2025-26 Filers

• •The new tax regime remains the default; opt out only if you have significant deductions and file Form 10-IEA on time.
• •Digital asset (VDA) transactions continue to be reported in AIS — every crypto trade, even in loss, must be reconciled and reported. Tax rate remains 30% flat plus applicable cess, with 1% TDS under Section 194S.
• •Dividends above ₹10,000 from a single company attract 10% TDS under Section 194 — verify in 26AS.
• •For senior citizens using the Section 87A rebate, ensure total income stays within the rebate ceiling; AIS often reveals overlooked interest that breaches it.

Practical Filing Checklist

Before you click "Verify":

1. All TDS in Form 16/16A tallies with 26AS

2. All AIS income appears in your ITR (or feedback submitted)

3. Capital gains statements from brokers match AIS security transactions

4. Bank interest matches interest certificates from every bank

5. High-value SFT entries (property, MF, credit card) are explainable

6. Advance tax and self-assessment tax challans reflect in 26AS

E-Square Tip: Save a dated PDF snapshot of your AIS, TIS and 26AS on the day you file, along with any feedback acknowledgment numbers. If the department raises a query two years later, this frozen snapshot is your strongest defence — the online AIS keeps updating as new data flows in, and you cannot always retrieve the version you actually relied on at filing time.
