Yes, you can invest more than Rs 50,000 in NPS Tier 1. There is no upper contribution limit on Tier 1.

The tax deduction works in layers:

Section 80CCD(1): Contributions up to 10% of basic salary (salaried) or 20% of gross income (self-employed), subject to the overall Rs 1.5 lakh cap under Section 80C. If you have already used up Rs 1.5 lakh with PPF, ELSS, or LIC, additional NPS here gives no further deduction.

Section 80CCD(1B): An additional Rs 50,000 deduction, completely separate from the Rs 1.5 lakh 80C limit.

Section 80CCD(2): If your employer contributes to NPS, up to 14% of basic + DA (or 10% for private sector) is deductible with no upper cap. Available under both old and new tax regimes.

So if you invest Rs 2 lakh in Tier 1:
- Rs 1.5 lakh: deductible under 80CCD(1) within 80C
- Rs 50,000: extra deduction under 80CCD(1B)
- Beyond Rs 2 lakh: no further income tax deduction, but the corpus still grows tax-free until withdrawal.

Key caveat: 80CCD(1) and 80CCD(1B) are only available under the old tax regime.
