Form 16 vs AIS vs Form 26AS: How to Match Tax Details Before Filing ITR for AY 2026-27

Every salaried employee, freelancer or pensioner filing an income tax return runs into the same moment: Form 16 says one number, the Annual Information Statement (AIS) says another, and Form 26AS shows something else again. None of the three documents are wrong by default — they exist for different reasons and are built from different data. Form 16 is your employer's record of your salary and the tax deducted from it. Form 26AS is a tax-credit statement. AIS is a much wider financial summary compiled from banks, employers, registrars and other reporting entities.

Before filing, compare all three: use Form 26AS to confirm tax credit, AIS to check for additional income, and Form 16 as your salary reference — then reconcile the differences. This guide covers all three together; for a deeper walkthrough of any single document, see Form 16 Explained and Form 26AS and AIS: Your Tax Credit Statement Explained.

Form 16, AIS and Form 26AS at a Glance

What Is Form 16?

Form 16 is the annual TDS certificate your employer issues after deducting tax from your salary through the year — proof that tax was deducted and, separately, that it was deposited with the government.

Employers issue it to any employee whose salary was subject to TDS. Under the Income-tax Rules, employers must issue Form 16 by 15 June of the following financial year — for FY 2025-26, that's 15 June 2026. Confirm this date on the official portal if you're reading this later, since due dates can shift.

Form 16 is not a salary slip. A salary slip shows monthly pay; Form 16 is an annual, employer-certified statement of your total salary, exemptions, deductions and TDS, meant specifically for tax purposes.

If you changed jobs, each employer who deducted TDS should issue a separate Form 16 for your period there — add the salaries together when filing, since a new employer's payroll often doesn't know your earlier employer's numbers unless you declared them.

If an employer doesn't issue Form 16 — common with short stints, low salaries below the TDS threshold, or administrative delay — you can still file. Salary slips, your employment contract, bank statements, and Form 26AS/AIS can substitute. What matters is that your reported income is complete and accurate, not that you hold a specific certificate. See Form 16 Explained for a full walkthrough of both parts and how to read them.

Form 16 Part A

Part A is generated through TRACES and is a factual, system-verified record. It contains:

• Employer's TAN (Tax Deduction and Collection Account Number) and PAN
• Your PAN
• Employer and employee name and address
• The period of employment with that employer during the financial year
• Quarter-wise summary of TDS deducted and deposited
• A certificate/authentication number that lets you verify it was genuinely downloaded from TRACES

Since Part A draws on the same TDS-return data that feeds Form 26AS, its TDS figures should generally match Form 26AS — if they don't, that's a mismatch worth investigating.

Form 16 Part B

Part B is prepared by the employer directly (not centrally generated) and lays out the salary and tax computation:

• Gross salary, including basic pay, allowances and any bonus
• Exempt allowances, such as the exempt portion of HRA or LTA where applicable
• Value of perquisites, if any
• Deductions from salary, such as professional tax
• Standard deduction
• Chapter VI-A deductions the employer considered (Section 80C, 80D, and similar, based on the proofs you submitted)
• Net taxable income
• Tax computed, along with rebate, surcharge and cess where applicable
• The tax regime the employer used for calculating your TDS

Part B reflects the employer's payroll calculation based on the declarations and proofs you gave them — it is not automatically your final, complete tax position. Income the employer didn't know about (bank interest, capital gains, a second job, rent), or investments that differed from your declaration, can change your real liability. The ITR is where you report your complete picture, not a copy of Form 16.

What Is Form 26AS?

Form 26AS is a tax credit statement, generated by the Income Tax Department from TDS and TCS returns filed by deductors and collectors, and viewable through the TRACES portal. Since AIS was introduced, Form 26AS has narrowed to primarily confirm: TDS deducted by employers, banks and other deductors; TCS, where applicable; advance tax you paid; self-assessment tax paid; and refund information, where processed.

Form 26AS matters because it's what the department checks when verifying the TDS credit you claim in your ITR — if a TDS amount doesn't appear here, claiming it can flag your filing for a mismatch notice, even if Form 16 clearly shows the deduction. A salary figure in Form 16 may not fully match Form 26AS because Form 26AS reflects only what deductors have actually filed and deposited, not what your employer told you they deducted — a delay or error at the employer's end shows up here first.

Form 26AS differs from AIS in one key way: it doesn't carry AIS's broader financial-transaction data, and unlike AIS, you can't submit feedback directly on a Form 26AS entry — corrections have to go through the deductor's TDS return. See Form 26AS and AIS: Your Tax Credit Statement Explained for more on this relationship specifically.

What Is the Annual Information Statement?

The Annual Information Statement (AIS) is the Income Tax Department's broader financial information statement, built from data reported by employers, banks, registrars, brokers, mutual fund houses and other institutions. Per the official AIS page, its purpose is to show the taxpayer a comprehensive view of information before filing, support easier return pre-filling, and discourage under-reporting.

AIS has two parts: Part A carries basic taxpayer details (PAN, name, contact information); Part B carries the transaction-level data — TDS/TCS information, financial transactions reported under the Statement of Financial Transactions (SFT) framework, tax payments, and demand/refund details.

Categories commonly seen in AIS include salary, savings account and fixed deposit interest, dividend income, securities and mutual fund transactions, capital gains-related information, property purchase or sale, rent received, foreign remittances, TDS/TCS, GST turnover or other business information where applicable, and other reported financial transactions.

An AIS entry does not automatically mean the full amount shown is taxable, or entirely yours to report as-is. The department's own AIS documentation states AIS reflects information "presently available" and may not capture every transaction — treat it as a strong starting checklist, not a final verdict. A few clarifications worth internalising:

• Gross value, not gain: some entries show the gross transaction value rather than income or gain — a property sale may show the full sale consideration, not your capital gain after cost of acquisition.
• Duplicates happen when more than one reporting entity submits overlapping information about the same transaction.
• Joint transactions — a jointly held account, property, or demat holding — can appear at the full value against each holder's PAN, though only a share actually belongs to each person.
• Securities sale value ≠ capital gains. AIS may show what you sold shares or units for; your taxable gain is that value minus your cost of acquisition (and, for equities, applicable holding-period rules) — a calculation you still do yourself, using your broker or mutual fund statement. See the Capital Gains Tax Guide for how that calculation actually works.

AIS is a research tool for catching income you might otherwise miss reporting — not a pre-computed final tax figure to copy over.

AIS vs TIS

The Taxpayer Information Summary (TIS) is a simplified, aggregated version of AIS. Instead of showing every individual reported transaction, TIS groups them by category and shows both the "reported value" (as received from the source) and a "processed value" the system derives after applying basic de-duplication logic.

TIS is the version used to pre-fill values into your ITR where pre-filling is supported. In short: AIS is the detailed transaction list; TIS is the summarised, category-wise version built on top of it. You don't need to treat them as two separate mismatch problems — check AIS for the transaction-level detail, and treat TIS as the "what the system currently thinks your total is" summary for each category.

Form 16 vs AIS vs Form 26AS Comparison

Why Form 16, AIS and Form 26AS May Not Match

• Employer filed the TDS return late — the quarterly return hasn't been processed yet, so Form 16's TDS hasn't reached Form 26AS.
• Employer entered the wrong PAN — the credit attaches to a different PAN and never shows up in your Form 26AS, even though tax was genuinely deducted.
• TDS was deducted but not deposited — less common, but it happens.
• A corrected TDS return is still processing — fixes (like a PAN correction) take time to reflect.
• Salary from a previous employer is missing — your latest employer's Form 16 usually excludes it unless you declared it.
• AIS shows bank interest not in Form 16 — expected; Form 16 is a salary-only document.
• Dividend income is missing from payroll records — dividends have nothing to do with your employer.
• AIS shows duplicate transactions — more than one reporting entity submitted overlapping data.
• A mutual fund or share sale value is confused with the taxable gain — AIS often shows the gross sale value, not your gain.
• A joint property transaction is reported in full against each co-owner's PAN.
• Income belongs to a different financial year — a transaction near year-end, or reported with a lag, can look misplaced.
• You changed jobs mid-year, and each employer's TDS filing reflects only their portion of your salary.
• The employer considered a deduction that turned out ineligible — for example, an 80C investment declared but not actually made.
• You invested after submitting your declaration, so payroll's TDS calculation is based on stale assumptions.
• You're checking the wrong assessment year — comparing FY 2024-25 data against an AY 2026-27 return is a common, avoidable error.
• A refund or tax payment hasn't updated yet in the system.
• Data reported by a bank, broker, employer or registrar is simply wrong at source — exactly what AIS feedback exists to address.

How to Match Form 16, AIS and Form 26AS Before Filing ITR

1. Confirm PAN, name and assessment year — check Form 16, Form 26AS and AIS are all for the same PAN and AY 2026-27. Mismatched years is the most common self-inflicted error.
2. Add income from all employers — list every Form 16 you received and add the salaries together first.
3. Match salary and TDS — compare the combined total from Form 16 against AIS and Form 26AS; use bank credits as a cross-check if numbers look off.
4. Check savings and fixed deposit interest — cross-verify AIS against your passbook or interest certificates; this rarely appears in Form 16.
5. Check dividend income — compare AIS entries against demat/broker statements or dividend advice.
6. Review share and mutual fund transactions — pull capital gains statements and calculate actual gains; don't use the AIS transaction value directly.
7. Check property-related information — verify against your sale deed, confirming your actual share if jointly owned.
8. Verify advance tax and self-assessment tax — match challan receipts against Form 26AS and AIS.
9. Check deductions and exemptions — confirm the Chapter VI-A deductions Form 16 assumed actually match proofs you hold, not just your initial declaration.
10. Reconcile the final taxable income — compute your total yourself (or via a computation sheet), or use the income tax calculator as a cross-check, rather than trusting any single document.
11. Save supporting records — salary slips, bank statements, interest certificates, broker statements, challans, and Form 16 from every employer.
12. File only after reviewing pre-filled details — the ITR utility often pre-fills from AIS/TIS and Form 26AS; check every figure against your own reconciliation before submitting. Our step-by-step guide to filing your ITR online covers this process end to end.

Practical Reconciliation Table

What to Do If Form 16 Is Incorrect

• Wrong PAN: ask the employer for a corrected Form 16 and a corrected TDS return — a wrong PAN means the credit may never reach Form 26AS.
• Incorrect salary amount: request a corrected Form 16 from HR/payroll; use salary slips as the accurate reference meanwhile.
• Incorrect deductions: calculate your own correct figure for the ITR — you're not bound to copy the employer's assumption.
• TDS mismatch: check Form 26AS first; if genuinely not reflected, resolve with the deductor before relying on it.
• Previous employer income missing: add it yourself using the earlier Form 16.
• Wrong tax regime assumption: employers pick a default regime for TDS purposes, but you can choose differently when filing your ITR — see Old Tax Regime vs New Tax Regime to check which applies to you.
• Incorrect exemption calculation: recompute exemptions (like HRA) yourself using your actual rent and salary structure — the HRA exemption calculator can help.

The underlying principle: your ITR must reflect your correct income and tax position — Form 16 is a reference, not something to copy verbatim if you know it's wrong.

What to Do If TDS Is Not Showing in Form 26AS

1. Contact the deductor first — your employer or the bank/institution that deducted the tax — and ask whether the TDS return has been filed.
2. Check whether your PAN was correctly quoted — a PAN error is one of the most common causes.
3. Ask whether a revised or corrected TDS return is needed, and request a timeline.
4. Keep salary slips and bank statements as evidence tax was actually deducted.
5. Avoid claiming unsupported TDS credit — this can trigger a mismatch notice; better to get the credit reflected properly, or file and revise once it's fixed.
6. For material amounts, or an unresponsive deductor, consider professional help on the right approach, including whether to file on time and revise later.

What to Do If AIS Information Is Incorrect

Review each AIS entry and use the built-in feedback option, available directly against the transaction. Based on currently available AIS feedback options, you can generally indicate that:

• The information is correct
• The information is correct but only partially
• The information relates to a different person or PAN
• The information is a duplicate or an amount already reported elsewhere
• The information is denied — the transaction did not happen as described
• The taxability differs from the amount reported (relevant for cases like the gross-vs-gain issue with securities)
• The transaction actually belongs to a different financial year

Feedback options can be updated by the department over time, so check the current list on the AIS portal itself before assuming these are the only categories available.

Submitting feedback records your response and is visible in your activity history, but it does not always instantly remove or overwrite the original reported entry — the reporting source may need to separately correct their submission. Treat AIS feedback as documenting your position clearly, not as an automatic fix.

Should You Delay Filing ITR Because AIS Is Wrong?

Not usually — and definitely not for a minor, clearly explainable discrepancy. For a duplicate entry, a gross value where you know the true taxable amount is lower, or a joint-transaction entry you can document your real share of: submit feedback, keep your documents, and file with the correct income from your own records.

A material mismatch involving missing TDS credit that would meaningfully change your tax payable is different — try resolving it with the deductor first if time allows. If the deadline is close and it's unresolved, file with your correct, documented position and use the revised return facility once the TDS credit is fixed.

What you shouldn't do is skip the deadline hoping AIS "sorts itself out." Filing on time and correcting afterward through a revised return is almost always safer than missing deadlines — see ITR Filing Mistakes for the errors that most often delay refunds and trigger notices. For large mismatches, disputed property transactions, or multi-year discrepancies, a tax professional's advice is worth the cost.

Can You File ITR Without Form 16?

Yes. Form 16 is a convenience document, not a legal precondition for filing. If the employer hasn't issued it yet, your stint was short, or your income was below the TDS threshold, you can still file using:

• Salary slips for the year
• Bank statements showing salary credits
• Your employment contract or appointment letter, for salary structure reference
• Form 26AS, to confirm any TDS that was deposited
• AIS, to check for other reported income
• Interest certificates, dividend statements, and other tax certificates you hold
• Proof of deductions you're claiming (insurance premiums, investment receipts, and similar)
• Records of any other income you've earned

What matters is that the return contains your complete and correct income from every source — salary, interest, dividends, capital gains, rental income, and anything else applicable — not that you're holding a specific certificate.

Common Examples

1. Salary matches but TDS is missing. Form 16 shows the correct salary and TDS, but Form 26AS doesn't reflect it — usually an unprocessed TDS return or a PAN error. Use Form 26AS as the authoritative source for what you can currently claim, follow up with the employer, and keep Form 16 and salary slips as evidence.

2. AIS shows FD interest not in Form 16. Expected, not a problem — Form 16 only covers salary. Add the FD interest using your bank's interest certificate.

3. You changed jobs during the year. Two Form 16s, two TDS figures, possibly two different regime assumptions from payroll. Add both employers' salary and TDS together and compute your own combined liability.

4. AIS shows the full share sale value. Shares sold for ₹5 lakh, bought for ₹3 lakh — AIS may show ₹5 lakh. Your taxable gain is roughly ₹2 lakh (before adjustments), from your broker's capital gains statement, not the ₹5 lakh figure.

5. A joint property transaction appears at full value. A property jointly sold for ₹80 lakh with equal ownership may show ₹80 lakh against each PAN. Report only your actual 50% share, supported by the sale deed.

6. A duplicate dividend or mutual fund transaction appears in AIS. The same payout reported twice through different channels. Cross-check against your demat/bank statement and use the duplicate feedback option once confirmed.

7. The employer considered a deduction you didn't actually claim. Form 16 assumed an 80C deduction you never actually made. Recompute using only deductions you can support with real proof — an unsupported deduction is a risk regardless of what Form 16 shows. If you're weighing genuine 80C options for next year, ELSS vs PPF is a useful comparison.

ITR Filing Documents Checklist for AY 2026-27

• Form 16 from all employers you worked for during FY 2025-26
• Form 26AS
• AIS
• TIS
• Salary slips
• Bank statements
• Interest certificates (savings account, fixed deposits)
• Home loan interest certificate, if applicable — see Home Loan Tax Benefits
• Rent receipts, if claiming HRA
• HRA-related documents (rent agreement, landlord PAN if required)
• Capital gains statements
• Broker/demat statements
• Mutual fund statements
• Dividend statements
• Property purchase or sale records
• Advance tax challans
• Self-assessment tax challans
• Insurance premium receipts
• Donation receipts (for deductions where applicable)
• Education loan interest certificate, if applicable
• Previous year's ITR, for reference
• Any tax notices or department communications received

Not every item applies to every taxpayer — what you actually need depends on your income sources and the deductions you're claiming. A salaried employee with no investments beyond a savings account needs a much shorter list than someone with capital gains, rental income and multiple deductions.

Records to Keep After Filing ITR

Keep an organised folder — physical or digital — with your filed ITR, the acknowledgement (ITR-V) and e-verification proof, your final computation-of-income sheet, Form 16 from every employer, Form 26AS and AIS as they stood when you filed, tax payment challans, and any AIS feedback you submitted along with what you based it on. Our guide to organising your financial documents covers a simple system for this.

Digital copies are genuinely useful: searchable, don't degrade, and quick to produce if the department raises a query years later. A simple structure like "FY 2025-26 > Form 16 / Bank Statements / Computation" makes anything findable in seconds. The computation sheet matters more than people expect — it's the one document showing exactly how you arrived at your final taxable income, invaluable if you ever need to explain a figure that differed from what AIS or Form 26AS showed at the time.

There's no single officially fixed retention period covered here — scrutiny and reassessment timelines vary by situation, so check current guidance on the official portal or with a tax professional rather than assuming a fixed number of years is always safe.

Mistakes to Avoid

1. Copying Form 16 figures into your ITR without checking AIS for additional income.
2. Ignoring bank interest because it doesn't appear on Form 16.
3. Treating a securities or property sale value as if it were the taxable gain.
4. Claiming TDS that doesn't appear in Form 26AS without first verifying and following up.
5. Forgetting to include income from a previous employer after a job change.
6. Selecting the wrong assessment year while checking or filing.
7. Ignoring foreign income or foreign asset reporting requirements where applicable.
8. Claiming deductions you can't actually support with proof.
9. Ignoring AIS duplicate entries instead of reviewing and giving feedback.
10. Filing without carefully reviewing pre-filled data from AIS/TIS and Form 26AS.
11. Reporting the gross value of a property transaction as if it were your income.
12. Assuming AIS captures every single financial transaction you've made.
13. Assuming every amount shown in AIS is automatically fully taxable as reported.
