Key Takeaways & Recommendations
🏛️ For Old Regime Loyalists
Continue if you have substantial deductions. The government hasn’t discontinued this regime, but it’s becoming less attractive each year.
🚀 For New Regime Adopters
Budget 2025 made the new regime more attractive with lower rates and higher standard deduction. Most taxpayers will benefit.
⚠️ Important Consideration
You can switch regimes every year! Evaluate both options annually based on your investments and deductions.
