5Frequently 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 The 12% and 28% slabs were withdrawn under GST 2.0.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?

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.

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