Honestly, your CA might be slightly misleading you here — or at least not giving you the full picture on Tier 2.
Here's the thing — NPS Tier 2 has NO tax benefit for private sector employees. Zero. The tax deduction under Section 80C for Tier 2 contributions is only available to Central Government employees, and even for them there's a 3-year lock-in attached to it. If you're in a private company in Bangalore, that benefit simply doesn't apply to you. So if someone's selling you Tier 2 purely as a tax saving tool, that's wrong.
What Tier 2 actually is — it's basically a flexible investment account linked to your NPS. No lock-in, you can withdraw anytime. Funds are managed by the same pension fund managers like SBI Pension Fund, HDFC Pension, UTI Retirement Solutions. Expense ratios are very low, like 0.09% or so, which is genuinely one of the cheapest options in India.
So should you use it? Maybe, but not for tax saving. Use it if you want a low-cost actively managed fund alternative to park some money with flexibility. The equity option in Tier 2 has given decent returns historically. But compare it honestly with a direct plan ELSS or a Nifty 50 index fund — those are often simpler and more transparent.
For your situation specifically — 80C is maxed, Tier 1 NPS is handled by employer — the only real NPS tax angle left for you is the additional ₹50,000 under 80CCD(1B) through voluntary Tier 1 contributions. That's the one worth doing if you haven't already. That saves you real money.
Tier 2 for tax? Skip it. Tier 2 as a cheap flexible investment? Fine, but don't expect magic.
My suggestion: put any extra savings into a direct plan index fund via Zerodha Coin or MFCentral. Lower hassle, better liquidity, same or better returns. Tier 2 only makes sense if you're already disciplined with NPS and want everything under one roof.
