Frequently Asked Questions

Where can I find official due date notifications when CBDT/GSTN announces extensions?

Official sources: (1) CBDT circulars at incometaxindia.gov.in under "Circulars & Notifications"; (2) GSTN portal notifications at gst.gov.in under "News and Updates"; (3) MCA circulars at mca.gov.in. Subscribe to email notifications on each portal. For a consolidated view, the ICAI and TAXMANN.COM also publish extension notices promptly. Always verify from official government sources before treating an extension as confirmed.

Does advance tax apply to salaried employees?

Salaried individuals whose TDS is fully deducted by their employer are generally not required to pay advance tax separately (TDS is treated as advance tax). However, if a salaried person has additional income (rental, capital gains, business income, fixed deposit interest) that creates a tax liability exceeding ₹10,000 after TDS credit, advance tax becomes applicable. CA firms should review each salaried client's full income picture before concluding no advance tax is due.
