Sadguru Consultancy and Services
Over two decades of unwavering commitment to excellence in indirect tax advisory — built on field expertise, integrity, and a relentless drive to deliver results for our clients.
Sadguru Consultancy & Services was born in 2005 from a singular conviction: that businesses deserve better than guesswork when it comes to indirect tax compliance. What began as a one-man practice in Goregaon, Mumbai, has grown into a trusted advisory firm serving hundreds of businesses across India.
Our founder, Shri Rajan Mashelkar, recognised a critical gap in the market. Companies were struggling to navigate the labyrinth of Central Excise, Customs, and Service Tax regulations — often receiving generic advice that failed to address the nuances of their specific situations. Having spent over two decades inside the system, he understood not just the letter of the law, but the spirit behind it.
That insider perspective became our competitive edge. Over the years, Sadguru has expanded its expertise to encompass the full spectrum of indirect taxation — from the transition to GST in 2017 to specialized EOU, DGFT, and customs advisory. Today, we serve manufacturers, exporters, traders, service providers, and hospitality businesses with the same founding commitment: reliable, practical, and result-oriented consultancy.
