Hello,
Sorry for your loss.
First, any asset such as money or mutual funds investments received by way of inheritence after your uncle's demise are not taxable in your hands.
However when you will further distribute these assets without consideration, it will be regarded as a gift in recipient's hands and needs to be analysed accordingly.
Going by the limited facts stated above, I believe that the seven people mentioned above won't get covered within the defination of relative if you are the donor and therfore the further distribution should be taxable if the value of asset in each individual's hands more than INR 50k
Second, in case you choose to liquidate the mutual fund investments before distribution then the capital gains arising out of it will be first taxed in your hands. While doing that you are eligible to get deduction for cost of acquisition originally incurred by your uncle and also get the previous holding period counted while deciding its nature.
Third, its necessary that documentation part is well managed in such transaction so that any possible queries from tax department either to you or your relatives receiving such assets can be suitable dealt with.
Fourth, the recipients are required to file a return of income only if there total income from all sources is more than minimum exemption limit applicable in their situation.
Hope it answers your query.
Given the multiple aspects of your query, limited clarity emanating from writeup and the need to properly plan and document every aspect of it, I would advise you to take a telephonic consultation.
Best Regards,
