AIS vs Form 16: Which One Should You Trust While Filing ITR AY 2026-27?
Quick answer: Both AIS (Annual Information Statement) and Form 16 are important for filing your ITR, but they serve different purposes. Form 16 is your employer's official TDS certificate — it is the primary document for salaried income. AIS is the Income Tax Department's own view of your financial activity across the year, sourced from multiple reporting entities. If they differ, you must reconcile both before filing. Neither one alone is "complete."

When July approaches and ITR filing season opens, most salaried employees in India open two documents: Form 16 from their employer and the Annual Information Statement from the income tax portal. Very often, the numbers don't match — and that creates genuine confusion.
Which one is right? Which one should you enter in your return? Do you have to explain the gap?
This guide answers those questions plainly, without jargon, so you can file your AY 2026-27 return with clarity.
What Is AIS?
AIS stands for Annual Information Statement. The Income Tax Department introduced it in November 2021, and it replaced the older Form 26AS for most practical purposes.
You can access AIS by logging into the income tax e-filing portal (incometax.gov.in), going to "Services" and then clicking "Annual Information Statement."
What AIS shows:
- Salary income reported by your employer
- TDS deducted on salary (from the employer's TDS returns — Form 24Q)
- Interest income from savings accounts, fixed deposits, and recurring deposits
- Dividend income from mutual funds and stocks
- Proceeds from sale of securities, mutual fund units, or property
- Rent received (if any third party reported it)
- GST turnover (for business owners)
- Foreign remittances received or sent
- Information from banks, mutual fund houses, brokers, registrar offices, and other reporting entities
In short, AIS is the government's 360-degree picture of your financial life, built by collecting data from every entity that is legally required to report to the tax department.
What AIS does not always show correctly:
AIS depends on third parties — banks, employers, brokers — to report accurate data. If a bank enters the wrong PAN, your interest income shows up in someone else's AIS (or shows up twice in yours). If your employer filed a revised TDS return, the old and new figures may both appear temporarily. AIS is a reporting aggregation tool, not an error-free document.
What Is Form 16?
Form 16 is a TDS certificate issued by your employer under Section 203 of the Income Tax Act. It is split into two parts:
Part A is generated by the Income Tax Department's TRACES portal after your employer files their quarterly TDS returns (Form 24Q). It shows:
- Your employer's TAN and PAN
- Your PAN
- The total tax deducted from your salary each quarter
- The amount deposited with the government
Part B is prepared by your employer. It shows:
- Your gross salary
- Allowances and perquisites
- Deductions under Chapter VI-A (80C, 80D, HRA, etc.)
- Net taxable income under whichever regime you declared
- Total TDS deducted
Form 16 is your primary salary document. It is signed by your employer, and your employer bears legal responsibility for its accuracy under the Income Tax Act.
What Form 16 does not cover:
Form 16 only covers salary income and the TDS your employer deducted. It says nothing about:
- Interest from your personal bank accounts
- Dividend income
- Capital gains from selling stocks or mutual funds
- Freelance income or rental income (if any)
AIS vs Form 16: Key Differences

|---|---|---|
| Issued by | Income Tax Department (auto-generated) | Your employer |
| Legal basis | Section 285BB of the Income Tax Act | Section 203 of the Income Tax Act |
| Covers | All income types across the year | Salary income only |
| TDS shown | TDS from all sources (salary, bank, broker) | Only TDS on salary |
| Deductions | Not shown (no 80C, 80D details) | Shows all declared deductions |
| Tax regime | Not shown | Shows old or new regime declaration |
| Accuracy | Depends on reporting entities — can have errors | Employer's responsibility — generally reliable for salary |
| When to use | To check all income, cross-verify TDS credits | To fill salary income and Chapter VI-A deductions in ITR |
| Updatable | Yes — you can flag errors via the portal | No — only employer can issue a revised Form 16 |
| Available from | incometax.gov.in → AIS tab | Your employer (usually by June 15 each year) |
Why Does AIS Sometimes Differ from Form 16?
This is the question that causes the most anxiety during filing season. Here are the actual reasons:
1. Timing difference
Your employer files TDS returns quarterly (April–June, July–September, October–December, January–March). If the Q4 return has not been processed by the time you open AIS in June or July, the TDS for those months may not yet appear — making AIS look lower than Form 16.
2. Revised TDS returns
If your employer corrected an error in a previous quarter's TDS return, AIS may temporarily show both the original and revised entries, inflating the figure.
3. PAN mismatch
If your employer entered an incorrect PAN digit in their TDS return, the TDS credited in AIS may not match Form 16 at all. The TDS effectively goes "missing" from your account.
4. Salary components not on Form 16
Some employers do not include all perquisites or reimbursements in Form 16 but may still report them separately in TDS returns. AIS may show a higher gross figure.
5. Multiple employers in the same year
If you changed jobs, you have two Form 16s. AIS aggregates both. Unless you've received and combined both Form 16s, the comparison will not match.
6. Previous year adjustments
If a salary revision, arrear, or bonus paid in this financial year was linked to a prior assessment year, Form 16 may include it while AIS may classify it differently.
Which One Should You Trust While Filing ITR?
For salary income: Trust Form 16, with AIS as a cross-check.
Form 16 Part B is the authoritative document for:
- Your gross salary
- Deductions you declared (80C, HRA, 80D, etc.)
- Your declared tax regime
- Net taxable salary income
Enter this in your ITR under "Salary Income."
For TDS credit: Trust AIS (specifically, check Form 26AS too).
The actual TDS credit the Income Tax Department will apply against your liability is what appears in AIS / Form 26AS — because that is based on what your employer actually deposited. If your employer deducted ₹60,000 but only deposited ₹55,000, you can only claim ₹55,000 as TDS credit. The shortfall is your employer's liability, but you still need to account for it correctly.
For non-salary income: AIS is the only source.
Form 16 says nothing about interest, dividends, or capital gains. You must use AIS to find and report these correctly. Missing income that appears in AIS is one of the leading causes of income tax notices.
One practical rule: Enter the higher figure if AIS shows more income than Form 16, after confirming the additional income is genuinely yours. Underreporting income shown in AIS is a common trigger for scrutiny.
