Your salary TDS can go wrong by ₹50k–₹1L+ simply because you didn’t “pick a regime” on time.
Old vs New isn’t tax theory—it’s monthly cashflow.
Quick rule (FY 2025-26):
✅ ≤ ₹12.75L salary → New regime = ₹0 tax (₹75k standard deduction → taxable ₹12L, 87A rebate). 
When Old starts making sense (approx. Old-only benefits needed):
• ₹15L salary → ~₹5.19L deductions/exemptions to beat New
• ₹20L salary → ~₹6.83L deductions/exemptions to beat New
What you can still claim in New:
✅ Standard deduction ₹75,000 + ✅ Employer NPS u/s 80CCD(2) (+ limited notified allowances). 
Why inform payroll early (MOST important):
If you don’t intimate, employer deducts TDS under default New regime, and later switching means either cashflow hit now or refund later. 
Which regime are you choosing this year—Old or New?
