TAXATION Compliance & Regulatory FAQs
Essential compliance answers for Company Secretaries, Chartered Accountants, and corporate legal teams.
Q.What regulatory authorities are covered under Taxation on CorpLawUpdates.in?
Our Taxation hub delivers unified coverage across direct and indirect taxation: Central Board of Direct Taxes (CBDT) for corporate income tax, TDS/TCS, transfer pricing, and DTAA treaties; Central Board of Indirect Taxes and Customs (CBIC) for customs tariffs, FTA duty concessions, and central excise; and the GST Council / GSTN for e-invoicing, reverse charge mechanism (RCM), and GST return compliance.
Q.Are CBDT circulars and notifications legally binding on taxpayers and assessing officers?
Under Section 119 of the Income-tax Act, 1961, CBDT circulars and instructions are statutory directives legally binding on all subordinate Income Tax authorities and assessing officers. While taxpayers may challenge unfavorable circulars in court, benevolent circulars extending statutory deadlines, granting procedural relief, or clarifying exemptions are fully binding in favor of the taxpayer.
Q.What is the difference between a statutory tax notification and an administrative circular?
Statutory tax notifications amend parent rules (such as the Income-tax Rules, 1962, Customs Tariff Rules, or CGST Rules) and take legal force upon publication in the Gazette of India. Circulars provide administrative interpretations, operational guidelines, or date condonations to ensure consistent implementation by tax officers across India.
Q.What are the key corporate tax and GST filing deadlines tracked in 2026?
Key statutory deadlines include quarterly TDS payments (Challan 281 by 7th of following month), quarterly TDS statements (Form 24Q/26Q), corporate Tax Audit (Form 3CA/3CB-3CD) by 30 September, corporate ITR-6 by 31 October, monthly GSTR-1/GSTR-3B filings, and phase-wise mandatory e-invoicing for B2B and RCM transactions.
