Help regarding 80c

No............

Yes you definitely claim deduction u/s 80C. 

As per Section 80C payment of stamp duty, registration fees and other expenses for the purpose of transfer of such house to the assessee.

if a house is sold within five years of the end of the financial year in which it was purchased, the tax benefits claimed go out of the window. The tax deduction claimed for the principal repayment, stamp duty and registration under Sec 80C are reversed and the amount becomes taxable in the year of sale. Only the deduction of the interest payment under Section 24B is left untouched.

Please note the basic principle about the deduction given under section 80C (earlier section 88 etc.), is INVESTMENT.

Government wants capital for development of our country, and thus encouraged the investment by such deduction/s.

Also note that the minimum lock-in-period for various options available u/s. 80C is 5 years (except equity oriented option where its reduced to 3 years as additional boost).

Now, whether its specifically clarified in each option or not, but the principle of minimum lock in period of 5 years remains intact for all these investments, and hence ITO has right to disallow any such above referred mis-interpretation.
