Form 16 vs AIS vs Form 26AS: What Each Tax Record Shows

What each record is for

Think of the documents as different views, not three versions of one certificate. Form 16 is an employer-issued salary TDS certificate. AIS is the Income Tax Department's broader information view, including data reported by employers, banks and other reporting entities. Form 26AS is the tax-credit record used to check whether tax deducted or collected against your PAN appears in the department's system. Each can help identify a gap, but none alone proves that your return is complete.

For an income-tax return (ITR), use Form 16 to review salary, AIS to flag other reported items and Form 26AS to check TDS/TCS credits. AIS may not display every relevant transaction, so review your own records and report complete, accurate income [2].

Form 16: salary and employer TDS

Your employer gives Form 16 to you for salary and tax deducted under the salary-TDS process. Part A records the employer and employee identifiers and the salary-TDS deduction and deposit details. Part B, prepared by the employer, lays out salary, applicable exemptions and deductions reported for payroll, taxable salary and tax computation. The TRACES FAQ explains that the central TDS processing system generates Part A from the employer's filed quarterly statement, while the employer provides Part B [1].

Check your name, PAN, employer and year; compare salary and tax with payslips. If you changed jobs, review each certificate and whether the later employer considered previous salary and TDS. Form 16 does not cover unrelated income such as bank interest or capital gains.

AIS: a wider view of reported information

AIS groups information available to the tax department into categories. These can include TDS/TCS, specified financial transactions (SFT), tax payments, demand or refund information and other reported items. It also has a Taxpayer Information Summary (TIS), which aggregates information by category. The AIS FAQ describes reported values and values modified after taxpayer feedback or source confirmation, and says the accepted/confirmed TIS value may be used for return pre-filling where applicable [2].

An AIS deposit or investment entry is a prompt to check original bank or broker records, not automatically taxable income in that amount. For an error, submit feedback on the item and keep the acknowledgement. Feedback records your view but does not itself amend a bank's or employer's original filing.

Form 26AS: check tax credits, not your whole tax story

The Income Tax Department's AIS FAQ states that, from Assessment Year 2023–24 onwards, Form 26AS on TRACES displays TDS/TCS-related data, while other taxpayer information is available in AIS [2]. The records can therefore overlap on tax deducted or collected but are not interchangeable. For example, salary TDS may be visible in Form 16, AIS and Form 26AS; a purchase or interest entry may appear in AIS without being a Form 26AS tax credit.

Older department pages may describe broader contents. Follow the AIS-specific explanation for the distinction, then compare the statement for the relevant year with Form 16, Form 16A or challans. A mismatch signals a reporting or matching issue to investigate; it does not identify which record is wrong.

A practical reconciliation: compare like with like

Match the financial year in your documents and select its corresponding assessment year on the portal. Keep Form 16, AIS and Form 26AS with payslips, bank statements and challans. Compare salary in Form 16, reported items in AIS and credits in Form 26AS; do not treat a gross transaction, taxable income and net bank deposit as equivalent figures.

Illustration: Form 16 shows ₹48,000 salary TDS, while Form 26AS shows ₹42,000. Check year, PAN, employer TAN and statement update status, then compare payroll records. The ₹6,000 gap is illustrative, not proof of an error or entitlement. Verify any separate AIS interest entry against the bank statement.

How to correct a mismatch through official channels

If salary TDS is missing or incorrect in Form 26AS, contact the employer or other deductor with the relevant certificate, PAN and period. The department's mismatch FAQ says the deductor may need to file a revised TDS return [3]. Recheck the statement after the correction is processed. If the amount relates to your own advance-tax or self-assessment-tax challan, verify the challan number and PAN against the receipt before raising a query; the department's FAQ specifically points taxpayers to these details [3].

For an incorrect AIS item, submit feedback and contact the reporting entity if its source data needs correction. For a filed return, the portal's Tax Credit Mismatch service compares claimed credits or tax paid with Form 26AS and shows downloadable differences [4]. The department FAQ describes revised-return or rectification options depending on whether an intimation has arrived [3]; verify current eligibility and deadlines before acting.

A step-by-step check when records do not match

Start with a simple comparison sheet rather than trying to reconcile every number at once. Write down the financial year or tax year, assessment year where it applies, payer or employer, PAN, and the name of the document containing each amount. Then compare salary and employer-reported TDS with payslips and Form 16; compare the TDS credit with Form 26AS; and review other AIS entries against bank, broker, or property records. This separates three questions that are often mixed together: what income you earned, what another party reported, and what tax credit reached the portal [1] [2].

If an AIS value differs from your bank statement, identify the transaction date, account, reporting category, and whether the amount is gross, net, or a tax-credit figure. A deposit, sale value, or investment transaction is not automatically the taxable-income amount. Preserve the underlying statement and note the source's wording. If a figure was reported twice or under an unexpected category, use the portal's item-level feedback process where available, then ask the reporting institution to check its submission. AIS feedback records your response but does not edit the institution's underlying data [2].

For salary TDS, compare the certificate and the credit statement for the same year. Confirm the employee name, PAN, employer TAN, quarter or payment period, and tax amount before contacting payroll. If a correction is needed, send the employer or deductor the relevant evidence and ask whether it must file a revised statement. For self-assessment or advance-tax payments, use the challan receipt and confirm its identifiers rather than relying on the bank debit alone. The department describes these separate mismatch paths and the role of deductor corrections [3].

Keep a short issue log: the original amount, the record where it appears, the document that supports your position, the person or portal contacted, the date, and the acknowledgement number. Revisit the statement after the source correction has been processed. If a return has already been filed, first read the current portal instructions for the exact year and notice stage; the remedy can depend on timing and status. Do not assume that clicking an AIS feedback option automatically changes Form 26AS or updates a filed return [3] [4].

Before filing, retain a copy of the final reconciliation with your source documents. Share tax identifiers and account records only through the verified Income Tax Department portal or the official employer, bank, or deductor channel. Be cautious of unsolicited callers promising instant tax-credit fixes. This comparison is an organisational aid, not a determination of taxability; when an item is material or the correction route is unclear, consult a qualified tax professional with the relevant documents.
