In case of unlisted mutual funds, TDS is applicable for NRIs at the rate of 10% without indexation benefit. Birla Sunlife Income Plus is a debt fund, which means that if you redeem it after 3 years, long-term capital gains tax at the rate of 20% (with indexation benefit) will apply.
Therefore, you will still need to pay the balance tax after deducting the TDS which you have already paid.
All open-end funds are unlisted as they do not trade on an exchange. Closed-end funds and ETFs are usually listed and can be traded on a stock exchange.
