The initial corpus of INTACH was generated with a grant of Rs.5 Crores (Rs. 50 Million) from the Government of India. With support from the INTACH (UK) Trust and the Government of India, INTACH built its headquarters at 71, Lodi Estate, New Delhi.

To enhance and promote the cause of heritage conservation, INTACH has signed Memorandums of Understanding (MOU’s) with several national and international organizations. In recent years INTACH has been fortunate to receive support from the Central Government and several ministries such as Education and Human Resource Development, Environment and Forests, Tourism and Culture. A range of projects has been initiated through several state governments. Corporate houses, and international agencies such as UNESCO, World Monument Watch, the Helen Hamlyn Trust, UK and Jaisalmer in Jeopardy, UK, have all provided generous grants to INTACH for conservation work and other related activities.
