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.
Reconciling tax credits is the single most important pre-filing exercise for Indian taxpayers in 2026. The Income-tax Department now cross-checks every rupee of TDS, TCS, advance tax, and self-assessment tax against Form 26AS, the Annual Information Statement (AIS), and the Taxpayer Information Summary (TIS). A mismatch — even ₹500 — can delay your refund by months or trigger a Section 143(1) adjustment notice.
The Three Statements You Must Reconcile
Three documents form the backbone of credit reconciliation:
- Form 26AS — the consolidated tax credit ledger showing TDS, TCS, advance tax, self-assessment tax, refunds and high-value transactions.
- AIS — the granular financial summary capturing salary, interest, dividends, securities transactions, mutual fund redemptions, foreign remittances and more.
- TIS — a category-wise summary derived from AIS, with derived values that flow into ITR pre-fill.
How to Read Form 26AS
Download Form 26AS via the e-Filing portal under 'View Form 26AS' or directly from TRACES. Match each TDS entry against the corresponding Form 16, Form 16A, or Form 16B issued by the deductor. Verify the deductor's TAN, the section under which TDS was deducted, gross amount, tax deducted, and date of credit. Quarter-wise reconciliation prevents end-of-year surprises.
Decoding the AIS Pre-fill
AIS aggregates information from banks, mutual funds, depositories, registrars, sub-registrars, the GSTN, and foreign tax authorities under DTAA exchange-of-information clauses. Each entry shows reported value, processed value, and modified value. If an AIS entry is incorrect — duplicate, attributable to another PAN, or wrongly classified — submit feedback online; the system updates within 15-30 days.
Common Mismatches and Fixes
Frequent reconciliation issues include:
- TDS deducted but not deposited by the deductor — follow up and ask them to file revised TDS returns.
- Wrong PAN quoted by the deductor — AIS will show the entry under the wrong PAN; raise a correction request.
- Mutual fund SIP redemptions reported by AMC but the taxpayer claims them as exempt under Section 10(38) (pre-2018) — provide feedback in AIS.
- Interest income from FDs reported by bank but reinvested — taxable when accrued, not when withdrawn.
- Foreign-asset reporting mismatches with Schedule FA disclosures — reconcile FEMA filings.
Reconciling Advance Tax and Self-Assessment Tax
Advance tax and self-assessment tax challans (BSR code, challan serial, deposit date, amount) must appear in Part C of Form 26AS within 7-10 working days of payment. If they do not, raise an OLTAS query through your bank, attach the counterfoil, and follow up with the assessing officer. Never file ITR without verifying these challans are reflected.
Best Practices Before Hitting Submit
Reconcile your salary income with Form 16 Part B and AIS salary section. Match interest income against AIS bank-interest section. Cross-check capital gains with the broker's annual statement and AIS securities section. Verify dividend income against AIS dividend section and the company's RTA records. Save screenshots of feedback submissions as evidence.
Conclusion
Tax-credit reconciliation is no longer optional housekeeping — it is the single most reliable way to ensure a faster refund, fewer notices, and a clean assessment. Spend an evening matching 26AS, AIS, and TIS before filing your ITR for AY 2026-27 or AY 2027-28. Every rupee you reconcile today is a rupee the system will not question tomorrow.
