Pf interest taxability

Hello,

I left my job some 4 years back, and the EPF continues to accumulate interest. I understand that the interest earned each year AFTER the service is taxable.

Please could the tax experts kindly tell me:

1) Since the PF account is still not closed and the accumulated money (with earned interest) is still lying in that EPF account, do I need to consider the interest earned as taxable this year, or should it be considered taxable in the future year when I'll withdraw the EPF to my bank account?

2) If yes to above question, where should the interest earned by declared in ITR4 - Income from other sources?

Thanks in advance
