AIS vs Form 26AS vs TIS: Check All Three Before Filing ITR
If you are about to file your income tax return for FY 2025-26 (AY 2026-27), do not start with the figures your employer or bank handed you. Start with three government statements that the tax department has quietly built about you — Form 26AS, the Annual Information Statement (AIS) and the Taxpayer Information Summary (TIS). Reading only one of them, or none, is the single most common reason ordinary salaried filers later get a refund held back or a polite-but-alarming mismatch notice under Section 143(1).
The confusing part is that all three overlap but none is a complete picture on its own. Here is what each actually contains, how they differ, and the exact order in which a careful filer should reconcile them before hitting submit.
What Form 26AS Shows Today
Form 26AS used to be the all-in-one tax passbook. Since AY 2023-24 the department has stripped it back to its core job: it is now essentially your tax-paid statement. Think of it as proof of money that has already reached the government against your PAN.
Form 26AS today carries:
- TDS (tax deducted at source) by your employer, bank, tenant or any payer
- TCS (tax collected at source), for example on foreign remittances or some car purchases
- Advance tax and self-assessment tax you paid yourself
- Refunds already issued to you in the year
What it no longer emphasises is the income behind those deductions or your high-value spends. That detail moved to the AIS. So Form 26AS answers one question well — how much tax credit can I claim? — and nothing more.
What the AIS Adds That 26AS Doesn't
The Annual Information Statement is the wide-angle lens. Where 26AS lists tax paid, AIS lists the financial footprint that various reporting entities have flagged against your PAN across the year, spread over roughly 60 information categories.
That includes salary, interest from each bank account, dividend, mutual fund and share transactions, rent received, and Specified Financial Transactions (SFT) — the big-ticket items banks and registrars must report, such as large cash deposits, hefty credit-card bills, or property purchases above set thresholds.
AIS has two parts. Part A is your identity data. Part B is the money: every reported transaction, each with the deductor's name and the value. Crucially, every line carries a feedback option — your right to disagree with what was reported. This is the single most under-used feature in the whole system, and the one that quietly saves people from notices.
TIS: The Number the Portal Pre-Fills
If AIS is the raw ledger, the Taxpayer Information Summary (TIS) is the executive summary. It takes every AIS entry, removes duplicates, and rolls each income head into one clean processed value.
Say your AIS lists a dozen separate mutual-fund redemptions through the year. TIS doesn't make you add them up — it shows one net capital gains figure after de-duplication. That processed value is what flows into the pre-filled ITR on the portal.
This is exactly why TIS deserves caution rather than blind trust. Because it feeds your return automatically, any error inside it silently becomes an error in your filing. TIS can misclassify, double-count an entry that two parties reported, or value a capital gain using an assumption that doesn't match your real cost. Treat the pre-filled number as a draft, never the verdict.
The Reconciliation Order That Prevents Notices
The goal is simple: the income you declare should be defensible against what the department already sees. Work through it in this sequence rather than trusting any single screen.
- Pull all three from the e-filing portal — AIS, TIS and Form 26AS — for AY 2026-27. The PDF password is your PAN in lowercase plus date of birth (DDMMYYYY).
- Match tax credits in Form 26AS against your Form 16 and any interest certificates. The TDS you claim in your ITR must appear here, or the credit can be denied.
- Scan AIS Part B line by line. Look for income you forgot — a dormant savings account's interest, a small dividend, a side freelance payment.
- Sanity-check TIS against your own records — bank statements, broker capital-gains report, rent receipts. Don't let the pre-filled figure override reality.
- Flag every wrong entry using AIS feedback before you file.
The most frequent gap is interest income. Banks report savings and FD interest to AIS, but many filers leave it out because no Form 16 lands in their inbox for it. The department sees it; you missed it; the system flags the difference.
How to Fix a Wrong Entry the Right Way
When an AIS line is genuinely incorrect — income that isn't yours, a transaction counted twice, a figure that belongs to a joint holder — open that entry and submit online feedback. You pick from options such as the information being not fully correct, relating to another PAN, or being a duplicate.
A few rules keep this clean:
- Feedback does not auto-reduce your tax. It records your stance; the reporting entity may be asked to confirm. You still file on your true income.
- Don't stay silent on a real mismatch. An unexplained gap between AIS and your ITR is precisely what triggers an automated query.
- Keep proof. If you mark something as belonging to a spouse or as a duplicate, hold the supporting statement in case it's questioned later.
And if AIS missed some income you actually earned — it happens — you are still legally bound to declare it. The statement is the department's working draft, not a cap on your honesty.
Why This Matters More Each Year
The direction of travel is clear: India's tax system is becoming data-first. Every year more reporting entities — banks, registrars, depositories, fintechs — push more transactions into AIS, and the pre-filled return gets richer. That cuts manual effort but raises the cost of a careless mismatch, because the department's view of you is now detailed and largely automated.
The filer who wins is not the one who trusts the pre-filled number, nor the one who ignores AIS and files blind. It is the one who spends twenty minutes reconciling Form 26AS, AIS and TIS against their own records, corrects what's wrong through feedback, and declares the true total. Do that, and a refund tends to arrive faster and a notice tends never to come. Skip it, and you are betting that three government databases all happen to agree with a number you never checked.
