As an NRI you can invest in most mutual funds. It can be done online by registering on Jama.co.in.
You will need to source the funds for your investment from either your NRI (repatriable) or NRO (non-repatriable) bank account. Some paperwork may be required by law for the first transaction. The nuances vary if you are a resident of US/Canada or rest of the world (ROW).
Coming to the tax part,
- India has a Double Taxation Avoidance Agreement (DTAA) with most other countries. For any gains made in India, long term capital gains (LTCG) or short term capital gains (STCG) may be applicable. You can claim a foreign tax credit using the TDS (Tax Deducted at Source) certificate sent by the fund house.
- Some countries such as USA require the NRI to pay taxes on unrealized gains made during the tax year.
Like any other investor please make sure you invest only in Direct Plan variants of the Mutual Funds. You then get upto 40% more in long term portfolio size by avoiding commissions and brokers.
