Reconcile Form 26AS, AIS, and TIS before filing ITR for AY 2026-27. Fix TDS mismatches, advance tax errors, and AIS feedback to speed up refunds.
Reconciliation of Tax Credits
Before you file your Income Tax Return for AY 2027-28 (FY 2026-27), the Income-tax Department's Centralised Processing Centre (CPC) in Bengaluru will programmatically cross-match every rupee of tax credit you claim against three sources: Form 26AS, the Annual Information Statement (AIS), and the Taxpayer Information Summary (TIS). If the numbers do not align β even by Rs. 500 β you face a Section 143(1)(a) adjustment notice, a reduced or frozen refund, or an unexplained demand. Systematic reconciliation of all three statements before filing eliminates these outcomes. This guide shows you exactly how.
The Three Statements You Must Reconcile β and What Each One Does
The Department has layered three overlapping documents over the same underlying tax data. Each serves a different purpose; reconciling just one is not enough.
Form 26AS: The Authoritative Tax Credit Ledger
Form 26AS is the oldest of the three and remains the legally authoritative record of credits you can claim in your ITR. Its key sections:
- Part A β TDS on income other than salary: bank interest (Section 194A), professional fees (Section 194J), rent (Section 194I), contractor payments (Section 194C), property sales proceeds (Section 194-IA), and more.
- Part A1 β TDS entries where the deductor quoted your PAN incorrectly. Credits here cannot be automatically matched to your return β they require a deductor correction.
- Part B β TCS (tax collected at source) under Section 206C: motor vehicles above Rs. 10 lakh, foreign remittances under LRS (Section 206C(1G)), overseas tour packages, and goods sold above the prescribed threshold.
- Part C β Advance tax and self-assessment tax challans paid by you directly.
- Part D β Refunds issued in the year.
- Part F β TDS on immovable property transactions under Section 194-IA.
The single most important thing to understand about Form 26AS: it records what has been deposited with the government by the deductor, not merely what was deducted from your payment. A deductor can cut TDS from your invoice and yet fail to remit it to the government or fail to file a TDS return. Until the deductor files or corrects their return, the credit does not appear in your 26AS.
AIS: The Department's Comprehensive Financial Portrait of You
The Annual Information Statement, significantly expanded since 2021, aggregates data from more than 80 third-party source categories β far beyond what Form 26AS captures:
- Salary paid by employers
- Interest on fixed deposits, savings accounts, and recurring deposits reported by banks
- Dividend income reported by RTAs (CAMS, KFintech) and listed companies
- Securities transactions (equity, debt) reported by CDSL, NSDL, and stock exchanges
- Mutual fund purchase and redemption data from AMCs and depositories
- Property transactions reported by sub-registrars and state stamp authorities
- Foreign remittances under FEMA/DTAA exchange-of-information agreements
- GST turnover data linked to your PAN (for professionals, traders, and proprietors)
- Insurance policy data and high-value cash transactions
Each AIS entry shows three values you must understand:
- Reported value β what the source institution submitted to the Department
- Processed value β what the Department retained after de-duplication
- Modified value β what remains after your feedback is accepted
Your ITR must match the processed value, not the reported value. Filing with figures that differ from processed value without explanation is what triggers automated mismatch notices.
TIS: The Pre-Fill Bridge to Your ITR
The Taxpayer Information Summary is a category-level condensation of AIS data. It collapses individual transactions into the row-level totals that power ITR pre-fill β aggregate salary income, total interest income, total dividend income, capital gains by category, and so on.
Practical rule: Start your ITR pre-fill from TIS. Then compare every pre-filled figure against your own source documents β Form 16, Form 16A, broker capital gains report, bank FD certificate β before accepting or amending each field. If your AIS feedback has been accepted and processed, TIS will already reflect the corrected totals.
Step-by-Step: How to Access All Three Documents
All three live on incometax.gov.in (the e-filing portal). Do not confuse this with the MCA portal, which handles company filings.
To download Form 26AS:
- Log in to the e-filing portal with PAN and password.
- Navigate to e-File β Income Tax Returns β View Form 26AS.
- You will be redirected to TRACES (TDS Reconciliation Analysis and Correction Enabling System) at
tdscpc.gov.in. - Select Assessment Year 2027-28, choose format (PDF recommended for readability), and download. The PDF password is your date of birth in
DDMMYYYYformat. - Alternatively, log in to TRACES directly for more granular challan and TDS status queries.
To view AIS and TIS:
- After logging into the e-filing portal, go to Services β Annual Information Statement (AIS).
- The AIS landing page contains two tabs: AIS (transaction-level detail) and TIS (category-level summary).
- To download AIS as a PDF, click Download β PDF. The password is your PAN in lowercase + date of birth in
DDMMYYYY(e.g.,abcde1234f01011985). - For use with ITR preparation software, download the JSON format β most CA-grade ITR tools can import it directly and auto-populate schedules.
Timing discipline: Check AIS at least 45 days before your ITR due date (for non-audit cases, the due date for AY 2027-28 is 31 July 2027). This gives you time to submit feedback and have it processed before filing. Check again two to three days before filing to confirm all corrections are reflected.
How to Read Form 26AS β A Section-by-Section Reconciliation Checklist
For each entry in Part A, verify:
- Deductor name and TAN match the Form 16A or deduction certificate you hold.
- Section code is correct: 192 = salary, 194A = bank interest, 194C = contractor, 194I = rent, 194J = professional fees, 194-IA = property.
- Gross amount = your gross receipt before TDS.
- Tax deducted = the amount you will claim in Schedule TDS of your ITR.
- Status = "F" (Final). Status "U" (Unmatched) means the deductor's TDS return has not been filed or does not contain a matching entry. Status "P" (Provisional) means the return is filed but not fully processed. Only "F" entries are securely creditable.
Part A1 entries are a hard stop. If any entry appears here, your credit cannot be claimed until the deductor files a revised TDS return with your correct PAN. Do not file your ITR hoping the system will sort it out β it will not; CPC will deny the credit.
For Part C challans:
- Verify BSR code, challan serial number, date, and amount match your bank counterfoil or the NSDL Challan Status confirmation.
- Confirm the Assessment Year on the challan reads 2027-28 for FY 2026-27 payments. An incorrect AY means the payment is credited to the wrong year β you will need to approach your Assessing Officer for a correction, which can take 30β90 days.
Decoding AIS: Identifying and Fixing Incorrect Entries
The AIS is only as accurate as the data reported by third parties. These are the errors that appear most often in practice:
- Duplicate entries: The same FD interest reported twice β once by the branch, once by the treasury operations head office of the same bank.
- Gross vs. interest credited: Bank reports the full gross FD interest accrued in the year (including interest compounded but not yet paid out) rather than the amount actually credited to your account. The accrual basis is correct for tax purposes (interest is taxable when it accrues, not when it is received), but the amount may differ from what you see in your passbook.
- Wrong PAN attribution: Another person's property transaction or securities trade mapped to your PAN due to a data-entry error at the registrar or broker.
- Mutual fund redemptions double-counted: A switch between schemes is internally reported as a redemption (by the source scheme) and a fresh purchase (by the target scheme); the redemption component flows into AIS as a capital gain event even if you never received cash.
How to Submit AIS Feedback β Exact Steps
- On the AIS tab, locate the specific transaction entry.
- Click the feedback icon (speech bubble) to the right of the entry.
- Select one of the feedback types:
- Information is correct β no change needed
- Information is not fully correct β modify the amount and enter reason
- Information relates to another PAN / year β for genuine attribution errors
- Duplicate information β for double-counting by the same institution
- Information is denied β only where you are certain the transaction did not involve you
- Upload supporting documents if prompted (bank FD certificate, broker contract note, sub-registrar deed).
- Submit. Note down the feedback acknowledgement number and download a screenshot. This is your evidence if the matter is ever disputed.
Processing time: 15β30 calendar days for most feedback. Property and foreign-income disputes can take 45 days. If no correction is made and you disagree with the processed value, file your ITR with the correct figure, attach a note to that effect, and keep the feedback record as your defence against any subsequent Section 143(1) notice.
Reconciling Advance Tax and Self-Assessment Tax Challans
Advance tax errors are among the most avoidable yet most common causes of a refund mismatch. Use this sequence for FY 2026-27:
Step 1 β List every challan you paid:
| Instalment | Due Date | Amount (Rs.) | BSR Code | Challan Serial |
|---|---|---|---|---|
| Q1 | 15 Jun 2026 | β | β | β |
| Q2 | 15 Sep 2026 | β | β | β |
| Q3 | 15 Dec 2026 | β | β | β |
| Q4 | 15 Mar 2027 | β | β | β |
| Self-assessment | Before filing | β | β | β |
Step 2 β Verify each challan on TRACES: Go to tdscpc.gov.in β Challan Status Enquiry. Enter BSR code, challan serial, and date. A status of "Consumed/Matched" confirms the credit is in the government ledger against your PAN and AY.
Step 3 β Match to Part C of Form 26AS: Every challan verified in Step 2 must appear in Part C with the identical amount. A discrepancy of even Rs. 100 β possible if a typographical error was made during online payment β means the credit will not be fully applied.
Step 4 β For missing or incorrect challans: Approach your bank with the original counterfoil within 7β10 working days of payment; most discrepancies arising from bank-code or serial-number errors can be resolved by the bank directly through OLTAS. For corrections involving tax amounts or AY, the Assessing Officer must issue a correction order β allow 30β90 days.
Worked Example: Salaried + Freelance Taxpayer With a Live TDS Mismatch
Profile: Priya Menon, senior manager + part-time consultant, FY 2026-27.
| Income Source | Gross Amount (Rs.) | TDS Deducted (Rs.) | Section |
|---|---|---|---|
| Salary (employer) | 22,00,000 | 3,20,000 | 192 |
| FD interest (bank) | 1,60,000 | 16,000 | 194A |
| Consulting fee (startup) | 5,00,000 | 50,000 | 194J |
| Advance tax paid | β | 75,000 | Challan 280 |
| Expected total credits | β | 4,61,000 | β |
What Priya found when she opened Form 26AS in April 2027:
- Employer TDS (Section 192): Rs. 3,20,000 β β matches.
- Bank TDS (Section 194A): Rs. 13,500 β β short by Rs. 2,500. The Q4 TDS return for the bank's FD portfolio has not yet been filed (it is due 31 May 2027). The shortfall is timing, not an error.
- Startup's TDS (Section 194J): Rs. 0 β β critical gap. Part A1 shows an entry of Rs. 50,000 under a PAN that differs by one character from Priya's PAN β the startup's accounts team made a data-entry error.
- Advance tax Q2 challan (15 Sep 2026): Rs. 75,000 β β matches.
What Priya does:
- For the bank TDS shortfall (Rs. 2,500): She waits until the first week of June 2027 before filing. After 31 May 2027 β when all deductors' Q4 returns are due β she re-downloads Form 26AS and confirms the Rs. 16,000 appears in full. Total waiting time: roughly 6 weeks.
- For the startup's Part A1 mismatch (Rs. 50,000): She emails the startup's finance controller in April 2027 with a screenshot of the Part A1 entry and a copy of her invoices. The startup files a revised Q3 TDS return correcting the PAN. TRACES updates within 30 days. By late May 2027, the Rs. 50,000 migrates from Part A1 to Part A with status "F". Priya re-downloads 26AS to confirm.
Had she filed on 15 April 2027 without waiting: CPC's automated processing would have matched only Rs. 4,11,000 (Rs. 3,20,000 + Rs. 13,500 + Rs. 0 + Rs. 75,000 + Rs. 2,500 still missing from bank) of her claimed Rs. 4,61,000, generating a Section 143(1)(a) adjustment reducing her refund by Rs. 50,000 and raising a demand. Rectifying such a demand under Section 154 requires filing a rectification application and waiting 60β120 days for the CPC to process it. The six-week wait before filing would have saved months of follow-up.
Pitfalls to Avoid
1. Filing before Q4 TDS returns are processed. All deductors' Q4 TDS returns (covering JanuaryβMarch 2027) are due by 31 May 2027. Form 26AS is updated 5β7 working days after the deductor files. Filing your ITR in April or early May significantly increases your exposure to unprocessed credits.
2. Accepting pre-filled figures without verification. TIS-driven pre-fill is a convenience, not a guarantee of accuracy. Pre-fill can contain duplicates, misclassifications, or stale data. Always cross-check pre-filled income figures against your Form 16, Form 16A, bank FD certificates, broker capital gains statements, and mutual fund account statements before accepting them.
3. Missing TCS credits on foreign remittances and vehicle purchases. TCS under Section 206C(1G) applies on LRS remittances above Rs. 7 lakh in a financial year (at applicable rates), on overseas tour packages, and on motor vehicles costing more than Rs. 10 lakh. These appear in Part B of Form 26AS. A significant number of taxpayers fail to claim these credits in Schedule TCS of their ITR, losing money they are entitled to recover.
4. Ignoring AIS entries you do not recognise. The instinct is to dismiss an unfamiliar AIS entry as a "system error." In practice, it is more often a transaction you have forgotten β a dormant FD that auto-renewed, a mutual fund switch processed as a redemption, or a property transaction reported with a delay by the sub-registrar. Investigate before submitting feedback; denying a genuine transaction creates a contradiction the system will flag.
5. Submitting AIS feedback at the last minute. Feedback submitted the week before filing your ITR may not be processed in time. The 15β30 day processing window is typical but not guaranteed. Plan your feedback submissions at least 45 days before your filing date.
6. Entering the wrong Assessment Year on challan 280. When paying advance tax or self-assessment tax, the Assessment Year field on Challan 280 must read 2027-28 for FY 2026-27. Writing "2026-27" β a common error β credits the payment to the wrong year. You will not see it in AY 2027-28 Form 26AS, and correcting it requires a formal request to the Assessing Officer.
7. Not preserving evidence. AIS feedback acknowledgements, TRACES challan status screenshots, emails to deductors requesting PAN corrections β all of these are evidence. If a Section 143(1) notice arrives post-assessment, your documented reconciliation trail is your first and most effective line of defence.
Key Takeaways
- Form 26AS, AIS, and TIS contain overlapping but non-identical data β you must reconcile all three against your own source documents, not just one against another.
- Only "Final" (F) status entries in Form 26AS are fully creditable; "Unmatched" (U) or Part A1 entries require a deductor TDS correction before you file.
- Q4 TDS returns are due 31 May 2027 β filing before this date materially increases the risk of missing credits and triggering a Section 143(1)(a) adjustment notice.
- AIS feedback takes 15β30 days to update processed values; submit corrections at least 45 days before your ITR due date of 31 July 2027.
- Advance tax challan 280 must specify AY 2027-28 for FY 2026-27 payments; a wrong AY requires an Assessing Officer correction that can take 30β90 days.
- TCS credits on LRS remittances, overseas tour packages, and vehicle purchases sit in Part B of Form 26AS and are frequently unclaimed β check every year.
- Document your entire reconciliation process: save acknowledgement numbers, TRACES confirmations, and deductor communication; they protect you against post-assessment notices and make any rectification significantly faster.
