In this video, we explain the entire process that takes place for data analysis and verification by income tax department in a simple, practical, and fear-free manner.
1. What is AIS?
The Annual Information Statement (AIS) contains financial information collected from:
- Banks
- Employers
- Mutual funds
- Property registrars
- Other reporting institutions
AIS reflects transactions linked to the taxpayer’s PAN.
2. Role of TDS & Form 26AS
Tax Deducted at Source (TDS) is reported by deductors.
Mismatch between claimed TDS and reported TDS may trigger adjustment.
Form 26AS acts as a tax credit statement.
3. Data Matching Process
The system compares:
- Income declared in ITR
- Income appearing in AIS
- TDS/TCS credits
- High-value transactions
Significant variance may lead to notice or adjustment.
4. Why Transparency Matters
Under-reporting income or ignoring AIS discrepancies increases risk exposure.
Proactive reconciliation reduces future disputes.
Conclusion
Modern tax administration is data-driven. Taxpayers must reconcile AIS and TDS details before filing returns to ensure smooth compliance.
