Most discussions about NPS focus on the retirement account everyone knows about — but NPS actually offers two distinct account types with very different rules, and mixing them up is a common source of confusion.
Tier 1: the retirement account
This is the primary NPS account, mandatory if you want to open an NPS account at all, locked in until retirement age (with limited early exit provisions). Contributions qualify for tax deduction under Section 80CCD(1) within the overall 80C limit, plus an additional ₹50,000 deduction under Section 80CCD(1B) — a genuine extra tax-saving avenue beyond your standard 80C allowance.
Tier 2: the flexible savings account
This is an optional add-on account, available only if you already have a Tier 1 account, with no lock-in — you can withdraw anytime like a regular investment account. However, Tier 2 does not carry the same tax benefits as Tier 1 (for most subscribers), making it function more like a flexible investment option riding on NPS's fund management rather than a tax-saving instrument.
Which one should you actually use?
If your goal is retirement savings with tax benefits, Tier 1 is the one that matters — most people who mention "NPS" for tax planning are referring to Tier 1 contributions. Tier 2 makes sense only as an additional flexible investment option if you specifically want NPS's fund management style without a lock-in, which is a fairly niche use case compared to simply using mutual funds for flexible investing.
The 40% annuity rule, and why it surprises people
At retirement, at least 40% of your Tier 1 corpus must be used to purchase an annuity that pays you a monthly pension — this portion isn't available as a lump sum. The remaining up to 60% can be withdrawn tax-free. People planning around NPS sometimes forget this mandatory annuitization when estimating how much lump sum they'll actually have access to.
