Form 26AS vs AIS vs TIS: What’s the Difference and Why It Matters
Every filing season, someone on a credit or tax team pulls up a client’s PAN on the income tax portal and finds three statements staring back, each with a different number for what should be one picture. Which one do you actually trust? The honest answer is that Form 26AS, AIS and TIS were never built to say the same thing, and at Precisa, CA firms and lending teams run into this mismatch every year. They answer separate questions, and treating them as duplicates is what causes the mismatch scramble at filing time.
Key Takeaways
- Form 26AS shows only tax credits: TDS, TCS, advance tax, self-assessment tax and refunds linked to a PAN.
- AIS is the wider transaction record the tax department holds against that PAN, covering everything from savings interest to property sales.
- TIS is a category-wise, deduplicated summary of AIS, and its accepted values are what pre-fill the income tax return.
- For claiming TDS credit, Form 26AS is the authoritative document. For checking whether income is complete, AIS and TIS take over.
- Treating the three as interchangeable is how genuine income sources get missed during return prep, or how a lending team ends up trusting the wrong number for a borrower.
What Does Form 26AS Actually Show?
Form 26AS is a tax credit passbook, nothing more. It records what has already been paid or deducted against a PAN: TDS on salary or professional fees, TCS collected by sellers, advance tax, self-assessment tax and refunds issued. Over the years it has also picked up a few high-value transactions reported under the Statement of Financial Transaction framework, but its core job hasn’t changed. You access it through the “e-File” menu on the income tax portal, which routes to the TRACES system.
Because it’s built around actual credits, Form 26AS stays the reference point whenever the question is purely how much tax has already been paid against a PAN. A CA reconciling advance tax instalments before the final computation still starts here.
What Does AIS Cover That Form 26AS Doesn’t?
AIS, or the Annual Information Statement, is a different animal. It captures nearly every financial transaction reported against a PAN, whether or not tax was deducted on it. Bank interest, dividend income, mutual fund and share transactions, foreign remittances and property purchases can all show up here, sourced from banks, employers, registrars and other reporting entities.
The gap between the two is where most surprises live. A savings account paying ₹800 in interest generates no TDS and never touches Form 26AS, yet AIS still shows it, because the bank reported it and it’s still taxable income. Capital gains work the other way round: AIS shows the gross sale value of a mutual fund redemption, not the gain, so a ₹5 lakh redemption on units bought for ₹4 lakh shows as ₹5 lakh. The actual gain still needs working out separately.
How is TIS Different From AIS?
TIS, the Taxpayer Information Summary, is what you get once AIS has been cleaned up. Duplicate entries are merged, taxpayer feedback is factored in, and the result is a category-wise total meant for practical use. A return’s pre-fill draws from TIS, not the raw AIS feed. AIS is the evidence, TIS is the number that lands in the return.
Form 26AS, AIS and TIS at a Glance
| Form 26AS | AIS | TIS | |
|---|---|---|---|
| What it shows | Tax credits and a few high-value SFT entries | Nearly all reported financial transactions | Category-wise summary of AIS |
| Authoritative for | TDS/TCS credit claims | Income completeness | Pre-filled ITR values |
| Access point | e-File menu, via TRACES | AIS menu on the e-filing portal | Same AIS menu on the e-filing portal |
| Format | Online view | PDF or JSON download | PDF or JSON download |
| Editable by taxpayer | No | Yes, via feedback | Indirectly, once AIS feedback is accepted |
Why This Distinction Matters Beyond Return Filing
For a CA, the risk isn’t confusion between the three documents. It’s relying on only one of them. A return that matches Form 26AS perfectly can still trigger a notice under Section 133C or 143(1)(a) if income visible in AIS was never declared. Reconciling all three before submission, rather than after a notice arrives, is the difference between a routine filing and a client call nobody wants to make.
The same gap shows up on the lending side, and it’s one Precisa’s clients run into often. Self-employed borrowers hand over a Form 26AS or an AIS extract as proof of income, and it’s tempting to take those figures at face value. But a PAN-level tax statement doesn’t say whether that income is stable month to month, or whether declared income actually matches the credits landing in the borrower’s account. That’s the reconciliation Precisa’s GST and bank statement cross-analysis is built for, and it’s why credit bureau report analysis on Precisa pairs bureau data against actual bank activity, rather than treating either source as final on its own.
What Should You Do When the Three Don’t Match?
Start with Form 26AS to confirm TDS and advance-tax credits are correct. Move to AIS next, checking every entry against what the client has declared, and submit feedback on anything wrong or duplicated. Finally, check TIS to confirm the aggregated totals match your own computation, since a disputed AIS entry won’t feed into TIS cleanly while feedback is pending. Lending teams doing the equivalent check on a borrower can run the same figures against a GSTR analysis or an ITR analysis of the underlying bank data, and a GST reconciliation check against declared turnover, which is usually where the real story about cash flow sits.
Frequently Asked Questions
1. Do I need to declare income that shows in AIS but not in Form 26AS?
Yes. If the income is genuine, it must be declared regardless of whether tax was deducted on it. Savings interest below the TDS threshold is the common example: no TDS means it never reaches Form 26AS, but it’s already visible to the department through AIS.
2. Which statement should I use to claim TDS credit?
Form 26AS. It’s the recognised record of tax already paid or deducted against a PAN, and it’s what a return’s TDS claims get checked against.
3. Is Form 26AS being renamed to Form 168?
Under the Income-tax Act, 2025, the statement is referred to as Form 168 from tax year 2026-27 onward. For AY 2026-27 filings, covering FY 2025-26 income, it’s still Form 26AS. The change is a renumbering, not a change in what the statement covers.
4. Can incorrect AIS entries be corrected?
Yes. Each entry has a feedback option to flag it as incorrect, duplicated, or belonging to someone else. Until that feedback is reviewed, the disputed entry won’t feed cleanly into the TIS pre-fill.
5. Does TIS override my own income computation?
No. TIS is a convenience for pre-filling the return, not a substitute for working out taxable income, particularly for capital gains, where AIS and TIS show gross transaction values rather than the actual gain.
The Bottom Line
None of these three statements is wrong. They answer different questions, and once a CA or credit team uses each one for what it’s actually meant for, the annual scramble to reconcile mismatched numbers mostly disappears. If your team reconciles borrower income across bank statements, GST filings and bureau data by hand every month, it’s worth seeing how much of that Precisa can take off your plate.
