Three differently named documents on the income tax portal show related but distinct information about your financial year, and confusing them, or checking only one when you needed another, is a common source of frustration when reconciling figures before filing your ITR.
Form 26AS: The Original, Narrower Statement
Form 26AS is the older, more established of the three, showing TDS deducted on your income (salary, interest, professional fees, and so on) as reported by whoever deducted it, TCS collected on your behalf, advance tax and self-assessment tax you've paid, and certain high-value transactions reported by specified entities. It's essentially a consolidated record of tax already paid or collected against your PAN, which you use to claim credit for that tax when filing your ITR.
Annual Information Statement (AIS): A Much Broader View
AIS was introduced as a considerably fuller statement, going well beyond what Form 26AS covers. It includes everything in Form 26AS, plus additional categories: interest income, dividend income, securities and mutual fund transactions, foreign remittances, and various other financial transactions reported to the tax department by banks, registrars, and other specified entities. AIS gives a much fuller picture of your financial activity for the year, as visible to the tax department, than Form 26AS alone.
Taxpayer Information Summary (TIS): A Simplified Digest of AIS
TIS is a simplified, category-wise summary derived from AIS, presenting the same underlying information in a more condensed, easier-to-scan format, showing an aggregated figure for each category (like total interest income, total dividend income) rather than the detailed, transaction-level view AIS provides. Many taxpayers find TIS more useful for a quick check before filing, while AIS is more useful when you need to drill into the specific underlying transactions behind a summary figure.
Why Checking All Three (Or at Least AIS and 26AS) Matters
Before filing your ITR, cross-checking your own records against both Form 26AS (specifically for TDS/TCS credit you're claiming) and AIS (for the broader income picture, especially interest, dividends, and securities transactions you might have overlooked) helps catch discrepancies before they become a mismatch flagged by the department after filing. A common scenario: a taxpayer forgets to declare interest income from a fixed deposit at a smaller bank, which nonetheless shows up in AIS since the bank reported it, filing without checking AIS risks a mismatch notice later.
What to Do If AIS Shows Information You Believe Is Incorrect
The AIS portal includes a feedback mechanism specifically for this, allowing you to flag a specific entry as incorrect, duplicate, or not pertaining to you, with a reason, rather than simply ignoring an error and hoping it doesn't cause issues. This feedback doesn't automatically correct the record instantly, but it creates a documented dispute that's factored into how the department reconciles the information, and is far better than silently filing a return that doesn't match what AIS shows without any explanation on record.
How These Interact With Filing Your ITR
Your actual ITR should reflect your true income and the tax already paid or credited, using Form 26AS primarily to verify TDS/TCS credit claims, and AIS/TIS to cross-check that you haven't missed declaring any income source the department already has visibility into. Filing a return that significantly understates income relative to what AIS shows, without a documented reason (like a flagged, disputed entry), increases the likelihood of a query or notice, as discussed in our guide on responding to income tax notices.
Where to Actually Access These Documents
All three are accessible directly through the income tax e-filing portal (incometax.gov.in) after logging in with your PAN credentials, Form 26AS is typically accessed through a link to the TRACES portal from within the e-filing portal, while AIS and TIS have their own dedicated section within the same portal.
A Practical Pre-Filing Checklist
- Download and review your AIS for the relevant financial year, checking all income categories, not just salary
- Cross-check TDS and TCS figures in Form 26AS against your own salary slips, Form 16, and any other TDS certificates you've received
- Flag any AIS entries that appear incorrect or don't pertain to you, with a documented reason, before filing
- Ensure your ITR's declared income is consistent with what these statements show, or that you have a clear, defensible explanation for any difference
Frequently Asked Questions
If AIS shows an error, should I wait for it to be corrected before filing my ITR?
Generally no, you should file your ITR based on your actual, correct income and tax position within the deadline, while separately submitting feedback on the AIS discrepancy. Waiting for AIS correction before filing risks missing your filing deadline, which carries its own separate consequences as discussed in our belated return guide.
Does AIS replace the need to check Form 26AS separately?
AIS includes the same TDS/TCS information as Form 26AS plus much more, so checking AIS alone can be sufficient for most purposes, though some taxpayers and tax professionals still cross-check both as a matter of habit and thoroughness, particularly since Form 26AS has a longer-established, more stable reporting history.
Why does my AIS show a transaction I don't recognise at all?
This can happen due to reporting errors by the entity submitting the data, a PAN mismatch attributing someone else's transaction to your account, or in rare cases, potential misuse of your PAN. Investigate any unrecognised entry promptly, using the AIS feedback mechanism to flag it, rather than ignoring it.
Is TIS or AIS more useful for a first-time ITR filer?
TIS's simplified, aggregated view is often easier for a first-time filer to quickly scan and understand, while AIS becomes more useful once you need to investigate a specific figure or discrepancy in more transaction-level detail.
