The Income Tax Return (ITR) filing season is now in full swing. Taxpayers are focused on collecting all essential documents, such as salary slips, bank statements, interest certificates and dividend statements.

The primary objective of all taxpayers is to ensure that their tax returns are up to date, accurate and include all essential details. This step is significant because the Income Tax Department now cross-checks taxpayer details using sources such as Annual Information Statement (AIS), Taxpayer Information Summary (TIS), Form 26AS, banking institutions, brokers and other similar reporting platforms.

Even minor omissions or errors can result in notices, delayed refunds, scrutiny and objections. As a taxpayer, ensure you avoid mistakes and seek professional guidance if in doubt.
