Public Provident Fund subscription limits restrict annual contributions and bar non resident Indians from opening accounts. Any individual may, on his behalf or on behalf of a minor of whom he is the guardian, subscribe to the Public Provident Fund subject to the prescribed minimum and maximum annual amounts. Non-Resident Indians are not eligible to open an account under the Scheme, but a resident who subsequently becomes an NRI during the currency of the maturity period may continue to subscribe until maturity on a non-repatriation basis.
