Form 16 vs 26AS vs AIS — Fix a Mismatch Before Filing Your ITR (2026)
Verified July 2026 · General information, not tax advice — reconcile with your own documents or a professional before filing.
- Form 16 = employer's salary + TDS certificate.
- Form 26AS = tax credits (TDS/TCS) against your PAN.
- AIS = broad record of income and high-value transactions.
- Reconcile all three before filing to avoid a notice.
- Fix the source: deductor revises TDS return, or you give AIS feedback.
- Declare all income (interest, dividends), not just salary.
What each document is
| Document | Who issues it | What it shows |
|---|---|---|
| Form 16 | Your employer | Salary paid and TDS deducted on it |
| Form 26AS | Income-tax dept (TRACES) | TDS/TCS deposited against your PAN, advance tax, refunds |
| AIS | Income-tax dept | Salary, interest, dividends, shares/MF, property, and other reported transactions |
Think of it as three lenses on the same year: Form 16 is your salary view, 26AS is your tax-paid view, and the AIS is your whole-income view.
Think of it as three lenses on one year
A quick mental model saves a lot of confusion. Your financial year is one reality, and these three documents each photograph it from a different angle. Form 16 photographs your salary and the tax your employer cut on it. Form 26AS photographs every rupee of tax parked against your PAN — from your employer, your bank's TDS on interest, TCS on big purchases, and any advance tax you paid. The AIS photographs your whole financial footprint — not just tax, but the underlying incomes and high-value transactions themselves. When all three photographs agree, filing is trivial. When they don't, one of them is simply a picture the others haven't caught up with yet — and your job is to find which, and why, before you file.
Why they mismatch
- Late TDS deposit — your employer/bank cut TDS but deposited or filed it late, so it isn't yet in 26AS.
- Wrong PAN quoted by the deductor — the credit went to someone else's PAN.
- Extra income in AIS — FD/savings interest, dividends or share sales that aren't in Form 16.
- Duplicate or wrong AIS entries — the same transaction reported twice, or an amount misreported.
How to reconcile — step by step
- Download Form 16 (from your employer), and Form 26AS and the AIS from the income-tax portal.
- Match the TDS in Form 16 with the TDS shown in 26AS. If 26AS is short, the credit hasn't reached your PAN yet.
- Compare the income in the AIS with what you're declaring — add any interest/dividends you'd missed.
- If 26AS is wrong, ask the deductor to file a revised TDS return so the credit appears.
- If the AIS is wrong, submit online feedback marking the entry incorrect/duplicate.
- File your ITR on your actual income and the TDS truly reflected — keep proof of anything you corrected.
Don't forget the TIS
Alongside the AIS sits the TIS (Taxpayer Information Statement) — a simplified, category-wise summary of the AIS (total salary, total interest, total dividend, etc.). The AIS is the line-by-line detail; the TIS is the totals the department will pre-fill and process against. When you submit feedback on an AIS entry, the TIS updates automatically. Always glance at the TIS totals as your quick sanity check before filing.
How to download each document
| Document | Where to get it |
|---|---|
| Form 16 | From your employer (generated from TRACES); Part A = TDS, Part B = salary breakup |
| Form 26AS | Income-tax portal → e-File → Income Tax Returns → View Form 26AS (opens TRACES) |
| AIS / TIS | Income-tax portal → Services → Annual Information Statement (AIS) |
Download all of them before you start your return, not after — filing first and reconciling later is how avoidable notices happen.
Mismatch scenarios and how to fix each
| What you see | Likely cause | Fix |
|---|---|---|
| TDS in Form 16 > TDS in 26AS | Deductor deposited/filed TDS late or wrong PAN | Ask the deductor to file a revised TDS return; wait for 26AS to update before claiming |
| AIS shows income you don't recognise | Wrong PAN, duplicate, or another year's entry | Submit AIS feedback ("information is not correct" / "relates to other PAN or year" / "duplicate") |
| AIS shows interest/dividends you forgot | Genuine income not in Form 16 | Add it to your return and pay tax on it |
| Interest reported gross, TDS separate | Bank reports full interest; you assumed net | Declare the gross interest and claim the TDS |
The AIS feedback options
When an AIS entry is wrong, you can mark it with a specific feedback type: information is correct, not fully correct, relates to other PAN/year, duplicate/included in another entry, denied, or customised amount. Choose the accurate one and keep supporting proof — feedback doesn't erase your responsibility to declare real income, it just corrects genuinely wrong data.
What a mismatch actually triggers
After you file, the return is processed and you get an intimation under Section 143(1). If your claimed TDS exceeds what 26AS shows, the excess credit can be disallowed, creating a demand; if you under-reported income that's sitting in your AIS, you can get a mismatch communication asking you to explain or revise. Neither is a disaster, but both cost time — and reconciling upfront avoids them entirely.
If you spot the error after filing
- Before the deadline: file a revised return under Section 139(5) with the corrected figures — it replaces the original.
- After the deadline: you may be able to file an updated return (ITR-U), but only with additional tax — so it's far cheaper to get it right the first time.
Filing deadline
For most individuals not subject to audit, the ITR due date is typically 31 July of the assessment year. Reconciling Form 16, 26AS and AIS is the last thing to do before you hit submit — ideally a week or two before the deadline, so there's time to get a deductor to fix a TDS entry if needed.
The one rule that keeps you safe
Don't claim a TDS credit that isn't in your 26AS, and don't omit income that's in your AIS. Both are the classic triggers for an automated mismatch notice. If a credit is genuinely yours but missing, get the deductor to correct it first; if AIS income is genuinely wrong, flag it via feedback — then file clean.
A pre-filing reconciliation checklist
Run through this before you hit submit:
- Does the gross salary in your ITR match Form 16 Part B?
- Does the TDS you're claiming appear fully in Form 26AS?
- Have you added every interest entry from the AIS (savings, FD, RD)?
- Have you included dividends and any capital gains from shares/mutual funds shown in the AIS?
- Did you submit feedback on any AIS entry that's wrong or duplicated?
- If you changed jobs, did you add both Form 16s and apply deductions only once?
If all six tick, your return is far less likely to attract a mismatch notice.
Special cases worth a second look
- Freelancers / side income: the AIS often captures professional receipts and 194J/194C TDS — reconcile these even if you have no Form 16.
- Capital gains: the AIS shows share and mutual-fund sale values; compute the actual gain (not the sale value) and declare it — a common source of notices.
- Joint holdings: interest or property transactions may appear in both holders' AIS; declare your correct share and give feedback on the rest.
- Multiple bank accounts: small interest amounts across accounts add up in the AIS and are all taxable — don't skip the ₹500 here and there.
Why this matters more every year
The tax department's data-matching gets sharper each year — the AIS now pulls from banks, registrars, mutual funds, employers and property registrars. That means the days of "forgetting" small incomes are over: if it's in your AIS and not in your return, the system flags it automatically. The upside is that reconciling honestly, once, protects you completely — a clean, matched return rarely gets a second look.
Changed jobs this year?
If you switched employers, you'll have two Form 16s and both TDS entries should show in 26AS. Add both salaries, apply the exemption/deduction limits once (not twice), and check for any short-deduction.

Frequently asked questions
What's the difference between Form 16, 26AS and AIS?
Form 16 = salary + TDS from employer; 26AS = tax credits against your PAN; AIS = broad income record.
What if 26AS and Form 16 don't match?
Find the cause (late deposit / wrong PAN), get a revised TDS return filed, and file on your real income and TDS.
Can I file if the AIS is wrong?
Yes — submit AIS feedback marking the entry wrong, then file with correct figures.
Why does AIS show more income than Form 16?
Because it also includes interest, dividends and share/property transactions — declare them all.
What is the TIS?
The Taxpayer Information Statement — a category-wise summary of the AIS that the department pre-fills and processes against. It updates when you give AIS feedback.
Where do I download Form 26AS and AIS?
Both from the income-tax portal: 26AS via e-File → View Form 26AS (TRACES), and the AIS/TIS via Services → Annual Information Statement.
Can I correct my return after filing if I missed AIS income?
Yes — file a revised return under Section 139(5) before the deadline, or an updated return (ITR-U) later with extra tax.
What happens if I ignore an AIS mismatch?
You may get an intimation under Section 143(1) or a mismatch communication, with a possible demand. Reconciling upfront avoids it.
