NPS (National Pension System) Explained: Tiers, Tax Benefits, and Pension Calculation

The National Pension System, NPS, is India retirement account that invests contributions in market-linked funds and pays out at retirement, mostly as a pension bought with part of the accumulated corpus. It has two accounts under one login: Tier 1, the retirement account with tax benefits and a lock-in to age 60, and Tier 2, a flexible investment account with no lock-in and, for most private-sector subscribers, no tax benefit. The tax story is what most people get wrong, because the famous extra deduction exists only under the old tax regime, while the employer-contribution deduction survives under both. All figures here are in Indian rupees.

Tier 1 versus Tier 2

Tier 1 is the pension account. It is mandatory for anyone joining NPS, it carries the tax benefits, and it is locked until age 60, with limited partial withdrawals for specified purposes such as a child higher education or marriage, a house purchase, or medical treatment, subject to conditions and limits. Tier 2 is a voluntary savings account available only to Tier 1 subscribers. It has no lock-in and withdrawals are allowed at any time, but it gives no dedicated tax deduction for most subscribers, so it is best understood as a convenient market-linked parking place, not a tax shelter.

Both tiers invest in the same fund menu: equity, corporate debt, government securities, and alternative assets, in proportions the subscriber chooses within prescribed limits, or through an auto-choice lifecycle option that reduces equity exposure with age. NPS does not guarantee returns: the corpus at retirement depends on contributions, fund performance, and charges, and any projection that promises a return is misleading.

The tax benefits, regime by regime

Three sections govern the tax story. Section 80CCD(1) covers your own contributions, within the overall ₹1.5 lakh section 80C ceiling shared with instruments such as PPF and ELSS. Section 80CCD(1B) gives an additional ₹50,000 deduction for your own Tier 1 contributions, over and above the ₹1.5 lakh ceiling, and it is available only under the old tax regime. Section 80CCD(2) covers employer contributions to your Tier 1 account, up to 14% of basic salary plus dearness allowance under the new regime, and it is available under both regimes.

The practical consequence: under the old regime, a salaried subscriber can shelter up to ₹2 lakh of personal contributions plus the employer contribution. Under the new regime, which is now the default, personal NPS contributions earn no deduction at all, and only the employer contribution route remains. Anyone contributing ₹50,000 a year to Tier 1 purely for the tax break while filing under the new regime is paying for a benefit they are not receiving, and should either switch regimes after advice or contribute for the retirement purpose rather than the deduction.

How the pension is calculated

The corpus at retirement is the future value of contributions compounded at the fund return. The calculator on this site runs it from your monthly contribution, expected return, and years to retirement. An illustration, not a promise: ₹10,000 a month for 30 years at an assumed 10% annual return is ₹36 lakh of contributions, and at an assumed 10% annual return compounded monthly the corpus reaches roughly ₹2.26 crore. The growth, about ₹1.90 crore, is compounding doing most of the work, which is why starting early matters more than contributing large amounts late.

At exit at age 60, the corpus is split. A lump sum portion can be withdrawn tax-free, and the remainder must buy an annuity, a regular pension, whose income is taxed at the subscriber slab rate in the year it is received. Government-sector subscribers face a higher mandatory annuity share than non-government subscribers under the amended rules, so the exact split depends on subscriber category and on the rules in force at exit, which should be checked at the time rather than assumed from this guide.

Choosing funds, and the mistakes to avoid

Fund choice matters less than contribution discipline, but it matters. A young subscriber can reasonably hold a higher equity share, because decades of compounding absorb market falls; a subscriber nearing 60 should hold less equity, because a market fall just before exit has no time to recover. The auto-choice option does this glide automatically and is a sensible default for subscribers who do not want to manage allocations.

The mistakes: contributing only for a deduction you do not get under your regime, stopping contributions in a market fall, which is selling low by another name, and treating a projection as a guarantee. NPS is a long, market-linked commitment. Its advantage is low cost and a long horizon, not certainty, and any comparison with PPF or fixed deposits should compare risk as well as return.
