Stepped concessionary rates on terminal benefits. For employees leaving service.
25% standard deduction on gross rent, plus actual expenses if better. For landlords with one or more properties.

Output VAT vs. input VAT, threshold check (Rs. 60M / quarter), schedule-by-schedule.
15% withholding on dividends from a resident company — a final tax, not reconciled or refunded.
