AIS vs Form 26AS: How to Reconcile Income Before Filing ITR 2025-26

Filing your income tax return for FY 2025-26 (AY 2026-27) without reconciling your Annual Information Statement (AIS) with Form 26AS is like submitting an exam answer sheet without checking against the question paper. The Income Tax Department already has detailed data about your income from multiple sources - banks, employers, brokers, mutual funds, and property registrars. If your ITR does not match this data, automated processing under Section 143(1) will flag the mismatch.

This guide provides a structured, head-wise reconciliation process for FY 2025-26 filing, explains the common mismatches and how to fix them, and covers the upcoming transition from Form 26AS to Form 168 under the new Act.

What Are AIS and Form 26AS and Why Must You Reconcile Them?

Form 26AS is the consolidated annual tax credit statement available on the TRACES portal. It shows TDS deducted from your income by employers, banks, and clients; TCS collected; advance tax and self-assessment tax paid; and refunds received. For FY 2025-26 filing, Form 26AS is your primary document for verifying TDS credits.

AIS (Annual Information Statement) is the comprehensive financial transaction statement introduced by the Income Tax Department. It goes far beyond Form 26AS - capturing salary, interest income, dividends, mutual fund transactions, share trades, property purchases/sales, foreign remittances under LRS, credit card payments, and all Specified Financial Transactions (SFT) reported by third parties.

For taxpayers managing income tax return filing, reconciling both documents before filing is the single most effective way to prevent post-filing notices, delayed refunds, and defective return flags.

Key Terms You Should Know

• Form 26AS (Section 203AA, ITA 1961): Consolidated tax credit statement showing TDS, TCS, advance tax, self-assessment tax, refunds, and high-value transactions. Accessed via TRACES or the e-filing portal. Becomes Form 168 from Tax Year 2026-27.
• AIS - Annual Information Statement (Section 285BB): Comprehensive financial statement capturing all transactions reported to the IT Department - salary, interest, dividends, securities, property, foreign remittances, SFT. More detailed than Form 26AS.
• TIS - Taxpayer Information Summary: Simplified, pre-fill-ready summary derived from AIS. Groups information by income heads (salary, interest, capital gains). Used by the e-filing portal to auto-populate ITR fields.
• SFT - Statement of Financial Transactions: Reports filed by banks, mutual funds, registrars, and other entities for high-value transactions (cash deposits above Rs 10 lakh, property above Rs 30 lakh, etc.). Feeds into AIS.
• Form 168 (IT Rules 2026): The new annual tax credit statement replacing Form 26AS from Tax Year 2026-27. Integrates AIS data for a unified view. Does not display Aadhaar - PAN-based only.
• Section 143(1) Intimation: Automated processing notice issued when the IT Department detects mismatches between filed ITR and AIS/Form 26AS data. Can result in additional tax demand or adjustment.

Who Needs to Reconcile AIS and Form 26AS for FY 2025-26?

• Salaried individuals - verify salary TDS in Form 26AS matches Form 16; verify bank interest, dividends, and mutual fund redemptions in AIS
• Freelancers and professionals - verify professional fee TDS under Section 194J in Form 26AS; verify all client payments in AIS
• Investors - verify capital gains from equity, mutual funds, and property sales in AIS; verify TDS on interest and dividends
• Landlords - verify TDS on rent under Section 194I/194IB in Form 26AS; verify rental income in AIS
• Senior citizens - verify TDS on FD/RD interest, pension income; verify that Form 15G/15H declarations resulted in correct nil-TDS entries
• Business owners - verify TDS on contract payments under Section 194C; verify GST turnover cross-reference with income declared in ITR

Individuals filing ITR filing for salary should start reconciliation at least 2-3 weeks before the 31 July 2026 deadline to allow time for corrections.

Legal Framework: AIS vs Form 26AS - What Each Covers

Note: For FY 2025-26 filing, use Form 26AS as the authoritative source for TDS credits (this directly affects your tax computation). Use AIS as the authoritative source for income completeness (this determines whether all income sources are declared). Mismatches between the two must be investigated before filing.

How to Reconcile AIS and Form 26AS: Step-by-Step Process

1. Download Both Documents From the E-Filing Portal. Log in to incometax.gov.in. Navigate to "Services" → "AIS" to download your Annual Information Statement. For Form 26AS, go to "Services" → "View Form 26AS" or access via TRACES portal. Download both for FY 2025-26 in PDF or JSON format.
2. Reconcile TDS Credits First (Form 26AS Focus). Compare TDS entries in Form 26AS with your Form 16 (salary), Form 16A (non-salary), and bank statements. Every TDS entry in Form 26AS should have a corresponding certificate. If TDS is missing from Form 26AS (deductor filed late or quoted wrong PAN), contact the deductor immediately. Professional TDS return filing verification can identify missing credits before they cause refund delays.
3. Reconcile Income Head by Head (AIS Focus). Go through each income head in AIS: salary (verify against Form 16), bank interest (verify against bank certificates), dividends (verify against depository statements), capital gains (verify against broker contract notes), rental income (verify against rent agreements). Flag any income in AIS that you have not declared.
4. Identify and Investigate Mismatches. Common mismatches: (a) interest income shown in AIS but not in your records - check if a bank FD auto-renewed and earned interest you forgot; (b) TDS in Form 26AS does not match Form 16 - employer may have filed a correction return; (c) duplicate entries in AIS - same transaction reported by multiple entities; (d) property sale showing in AIS but not your income - check if co-owner transaction is split correctly.
5. Submit AIS Feedback for Incorrect Entries. On the AIS portal, click the transaction you want to dispute. Select feedback type: "Information is not fully correct," "Information relates to other person," "Information is duplicate," or "Information is denied." Provide supporting details. The source entity gets notified and has 30 days to respond. Track status in the AIS feedback column.
6. Wait for Corrections Before Filing. Allow 10-30 days for third-party corrections to reflect. If a correction is pending but your filing deadline is approaching, file with the correct income figures and an explanatory note. The Department generally accepts returns where the taxpayer has taken reasonable steps to reconcile.
7. File Your ITR After Full Reconciliation. Once AIS and Form 26AS are reconciled, file your ITR with matching income and TDS figures. Cross-check the pre-filled data on the e-filing portal against your reconciled numbers. Do not blindly accept pre-filled data - it may be based on uncorrected AIS entries.

Documents Needed for Reconciliation

• Form 26AS - downloaded from TRACES or e-filing portal for FY 2025-26
• AIS and TIS - downloaded from the AIS section of the e-filing portal
• Form 16 / Form 130 - salary TDS certificate from employer (Form 16 for FY 2025-26)
• Form 16A / Form 131 - non-salary TDS certificates from banks, clients, tenants
• Bank statements - all savings, FD, and RD accounts for interest income verification
• Depository statements (CDSL/NSDL) - for equity and mutual fund transaction verification
• Broker contract notes - for capital gains computation and AIS cross-check
• Property registration documents - for property purchase/sale verification against AIS
• Mutual fund consolidated account statement (CAS) - from CAMS/KFintech for SIP, redemption verification
• Foreign remittance certificates - for LRS remittances shown in AIS

AIS vs Form 26AS: Common Mismatches and How to Fix Them

Note: For FY 2025-26, Form 26AS remains the authoritative document for TDS credits. If an amount appears in AIS but not in Form 26AS (e.g., interest income without TDS), you must still declare the income in your ITR even though there is no TDS credit to claim. Non-declaration is treated as concealment.

Common Mistakes to Avoid During Reconciliation

Mistake 1: Relying only on Form 26AS and ignoring AIS. Form 26AS shows TDS credits but misses income where no TDS was deducted - savings account interest below Rs 40,000, dividends below TDS threshold, and all SFT data. AIS captures these. A taxpayer who declares Rs 8 lakh income based on Form 26AS but has Rs 3.2 lakh additional interest visible in AIS faces an automated demand notice under Section 143(1) - plus penalty. Always check both. For investors with ITR for capital gains, AIS is the primary source for share and mutual fund transactions.

Mistake 2: Blindly accepting pre-filled ITR data. The e-filing portal pre-fills your ITR from TIS (derived from AIS). But TIS may contain uncorrected duplicates, provisional data, or entries awaiting feedback response. Always verify pre-filled numbers against your own records before submitting.

Mistake 3: Filing without waiting for AIS feedback resolution. If you submitted AIS feedback for an incorrect entry but the source has not yet responded, filing with the incorrect AIS amount will overstate your income. File with the correct amount supported by your documents, and retain proof of the AIS feedback submission.

Mistake 4: Not reconciling across all bank accounts. AIS captures interest income from every bank account linked to your PAN - including dormant accounts, joint accounts, and accounts in different cities. A common mismatch occurs when taxpayers forget about FD interest from a bank account they rarely use.

Mistake 5: Not understanding the Form 168 transition for next year. From Tax Year 2026-27, Form 26AS becomes Form 168 - integrating AIS data into a single unified statement. Professional tax planning services can help you prepare for this transition by ensuring your current reconciliation habits carry forward.

Penalties for Non-Disclosure of Income Visible in AIS

The Income Tax Department uses AIS data for automated matching under Section 143(1). If your ITR does not declare income that appears in AIS, the consequences are:

Under Section 143(1), an intimation is issued adjusting your tax liability to include the undeclared income. This can result in an additional tax demand plus interest at 1% per month under Section 234A (delay) and Section 234B (advance tax shortfall).

If the non-disclosure is determined to be misreporting or concealment, penalty under Section 270A of up to 200% of the tax payable on the concealed amount can be levied. For example, if Rs 3.2 lakh of FD interest was not declared, and the tax rate is 30%, the undeclared tax is Rs 96,000 - and the penalty can be up to Rs 1,92,000.

Late filing fee under Section 234F of Rs 5,000 (Rs 1,000 if income below Rs 5 lakh) applies if you file after the due date because you were waiting for reconciliation.

How AIS and Form 26AS Connect With the New Framework

The reconciliation process you follow for FY 2025-26 will evolve from Tax Year 2026-27 onwards. Form 26AS becomes Form 168 under the Income Tax Rules, 2026 - integrating AIS data to create a single unified tax credit and income statement. This means the separate reconciliation of two documents (Form 26AS + AIS) will eventually be simplified into verifying one comprehensive document.

For Tax Year 2026-27, employers file Form 138 (replacing Form 24Q) as the quarterly TDS return, and employees receive Form 130 (replacing Form 16) as the TDS certificate. The data flow becomes: Employer files Form 138 → TRACES generates Form 130 → Form 168 aggregates all TDS, income, and SFT data → ITR pre-filled from TIS derived from Form 168 and AIS.

For professional payroll processing services, ensuring accurate Form 138 filing is the first step in this chain - errors at the source cascade through the entire system.

What Each Statement Covers: AIS vs Form 26AS vs TIS

Key Takeaways

For FY 2025-26 ITR filing, use Form 26AS as the authoritative source for TDS credits and AIS as the authoritative source for income completeness. Both must be reconciled before filing - relying on only one leaves gaps.

Common mismatches include unreported bank interest, duplicate entries in AIS, missing TDS in Form 26AS, and property/capital gains transactions visible in AIS but not declared. Each has a specific resolution path.

Submit AIS feedback for incorrect entries through the e-filing portal. Allow 10-30 days for corrections. If correction is pending near filing deadline, file with correct amounts and retain proof of feedback submission.

From Tax Year 2026-27, Form 26AS becomes Form 168 - integrating AIS data into a unified statement. The current dual-reconciliation process will be simplified, but the habit of verifying pre-filled data against source documents remains essential.

Non-disclosure of income visible in AIS triggers Section 143(1) intimation, additional tax demand, interest at 1% per month, and potential penalty of up to 200% for concealment. Reconciliation is not optional - it is the most effective compliance safeguard.
