PPF Vs NSC

My notes from the rediff article:
http://www.rediff.com/getahead/2006/jun/14nsc.htm

1. Size of investment

NSC - Sold in denominations of Rs 100, Rs 500, Rs 1,000, Rs 5,000 and Rs 10,000
PPF - Rs 500 to 70k per annum(it is incremental)

2. Returns

NSC - 8% compounded bi-annually
PPF - 8% compounded annually

3. Tax Benefits

Both these investments fall under Section 80C. That means the investments made under this section are eligible for an income deduction upto a maximum Rs 1,00,000.

With PPF, you pay no tax on the interest you earn.
But, interest accrued on NSC is taxable. But, it is also eligible for a deduction under Section 80C.

4. Holding Period

NSC - 6 years
PPF - 15 years
- extendable for block of 5 years

5. Holding upper limit

NSC - No limit
PPF - One account only
- Separate acc. can be opened for child
- Tax benefit will be upto 70k only, and not 140k even though you may be depositing 140k

6. Holding pattern

NSC - Hold it jointly or you can hold it singly and nominate someone
PPF - Cannot be held jointly
