As the Income Tax Return (ITR) filing season begins, many taxpayers download their Annual Information Statement (AIS) and assume that whatever appears in AIS is their final taxable income.
This assumption can be costly.
AIS is an important compliance tool introduced by the Income Tax Department, but it is not a substitute for proper tax computation under the Income Tax Act. Many taxpayers either under-report income because certain items are missing from AIS or over-report income by blindly copying AIS figures without verification.
Understanding the difference between AIS, Form 26AS, TIS, and Actual Income is therefore essential for accurate ITR filing in 2026.
What is AIS?
AIS (Annual Information Statement) is a comprehensive statement available on the Income Tax Portal that contains financial information reported against a taxpayer’s PAN.
AIS may contain:
- Savings bank interest
- Fixed deposit interest
- Dividend income
- Share and mutual fund transactions
- Property transactions
- TDS/TCS information
- Foreign remittances
- High-value financial transactions
The purpose of AIS is to help taxpayers verify information available with the Income Tax Department before filing their return.
What is Form 26AS?
Form 26AS is a consolidated tax credit statement that reflects:
- TDS deducted by employers and banks
- TCS collected
- Advance tax paid
- Self-assessment tax paid
- Tax refunds received
For claiming tax credits, Form 26AS remains the most important document.
What is TIS?
TIS (Taxpayer Information Summary) is a simplified version of AIS.
It summarizes information appearing in AIS and incorporates feedback submitted by taxpayers.
Many taxpayers find TIS easier to understand because it provides a cleaner summary of financial information.
AIS vs Form 26AS vs TIS
| Particulars | Form 26AS | AIS | TIS |
|---|---|---|---|
| Main Purpose | Tax credit verification | Transaction reporting | Summarized information |
| TDS/TCS Details | Yes | Yes | Summary |
| Interest Income | Limited | Yes | Yes |
| Capital Market Transactions | No | Yes | Summary |
| Feedback Facility | No | Yes | Reflects feedback |
| Best Use | Claim tax credit | Verify transactions | Review summarized data |
What is Actual Income?
Actual Income means income chargeable to tax under the Income Tax Act after considering:
- Correct classification of income
- Exempt income
- Allowable deductions
- Capital gain computation
- Applicable exemptions and reliefs
Simply because a transaction appears in AIS does not automatically mean the entire amount is taxable.
Why AIS and Actual Income May Differ
AIS is an information-reporting tool. Taxable income is determined under the Income Tax Act.
Some common reasons for differences include:
1. Capital Gains
AIS may show sale proceeds of shares or mutual funds.
However, tax is payable only on the net capital gain after considering purchase cost and allowable adjustments.
2. Exempt Income
Certain incomes may appear in AIS but may not be taxable.
Examples:
- PPF interest
- Certain tax-free bond interest
- Agricultural income (subject to conditions)
3. Joint Ownership
AIS may show the entire interest or transaction value under one PAN even where ownership is shared.
4. Duplicate Reporting
Sometimes the same transaction may be reported more than once by reporting entities.
Practical Examples
Example 1 – Share Sale
AIS shows sale value of shares: ₹10,00,000
Purchase cost: ₹8,00,000
Actual taxable capital gain: ₹2,00,000
Tax is payable on ₹2,00,000 and not on ₹10,00,000.
Example 2 – Property Sale
AIS shows property sale value: ₹50 lakh
After considering acquisition cost and exemption claim, taxable capital gain may be significantly lower or even nil.
Example 3 – Joint Fixed Deposit
AIS shows interest income of ₹40,000.
If the FD is jointly owned on a 50:50 basis, taxable income may be only ₹20,000 in the hands of one taxpayer.
Common Mismatches Faced by Taxpayers
- Interest income mismatch
- TDS mismatch
- Duplicate entries
- Incorrect PAN mapping
- Capital gain reporting differences
- Joint ownership transactions
- Dormant bank account entries
Which Document Should Taxpayers Rely Upon?
| Purpose | Recommended Document |
| Tax Credit Verification | Form 26AS |
| Transaction Verification | AIS |
| Simplified Review | TIS |
| Final Tax Computation | Actual Records and Documents |
The safest approach is to reconcile all four before filing the return.

Conclusion
AIS, Form 26AS and TIS are valuable compliance tools, but none of them can replace proper tax computation based on actual records.
Taxpayers should use Form 26AS for tax credits, AIS for transaction verification, TIS for summarized information and their own records for final income computation.
A careful reconciliation before filing the return can help avoid notices, tax demands, penalties and unnecessary litigation.
In tax compliance, AIS should be treated as the starting point of verification—not the final determination of taxable income.
