Frequently Asked Questions

What are the current GST slabs in India?

Since 22 September 2025 the main slabs are 0%, 5%, 18% and 40%, plus 3% for gold and 0.25% for rough diamonds. The 12% and 28% slabs were withdrawn under GST 2.0.

Is the 12% GST slab still valid?

No. Charging 12% on an invoice dated on or after 22 September 2025 is incorrect and can attract a penalty under Section 122 of the CGST Act.

Which cities get the 50% HRA exemption?

Four metros for FY 2025-26. From 1 April 2026 the Income-tax Rules 2026 add Bengaluru, Pune, Hyderabad and Ahmedabad, making eight.

What replaced Section 80C?

Under the Income-tax Act 2025, in force 1 April 2026, Section 80C is renumbered Section 123. Limits are unchanged.
