Good to know
- The GSTIN checker confirms the structure only. Confirm the GSTIN is active on the GST portal before you invoice a new customer.
- TDS follows the Income-tax Act, 2025 (in force from 1 April 2026): section 392 for salary, section 393 for other payments. The earlier 1961 section (for example 194C) is shown only for matching.
- Due dates can be extended by notification. Check for extensions close to a deadline.
You can also just ask Atulya AI: TDS on rent, state code 27, pincode 202001, IFSC of Kotak, or paste a GSTIN or IFSC into Ask AI.
