Knowing nobody... read more in Kolkata, our Real Estate Agent connected us to Tanuja Sinha and Associates for our Accounting needs. We can only call this introduction a blessing from above.

Her professionalism is beyond compare, but her personal behaviour towards us was no less. We cannot praise her enough and recommend her whole heartedly for any NRIs like us (and non NRIs too) going through the uncertainties and complexities of property sales in Kolkata. Thank you Tanuja, and thank you to your expert team, gratefully, Supriyo and Indira Sen, Toronto, Canada

We would highly recommend her services to others.
She and her team is immensely knowledgeable, highly experienced, very professional and proactive. She is easily reachable and very prompt in her service.
Fortunately, a trusted friend recommended Tanuja Sinha to us. We were extremely impressed with her services. During our approximately two-hour meeting, Tanuja provided a comprehensive explanation of the entire selling process, and I subsequently signed the necessary paperwork. From that point onward, Tanuja efficiently managed all aspects of the transaction, including obtaining a PAN card, completing the mutation process, handling tax payments, and setting up a bank account. Her attention to detail was truly remarkable.
Tanuja also connected us with a highly competent real estate agent, who proved instrumental in securing a sale at a price that exceeded the market value by ten percent for a comparable flat.
The service we received from Tanuja exceeded our expectations. The entire experience was stress-free, and working with Tanuja was a pleasure. I wholeheartedly recommend Tanuja without any reservations.
