Hello @Swarnava_Addya,
There is no specific maximum limit on the amount of physical gold that a HUF can hold in India, provided the gold is acquired through legitimate means and its source is properly accounted for.
However, the CBDT has clarified that during a search operation, gold jewellery up to 500g for married women, 250g for unmarried women, and 100g for men applies.
