Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

I, as a current citizen and resident of USA, faced with lots of complicated situations around my India tax calculations and submissions for last around 15 years. I tried multiple tax advisors to resolve those issues - with no luck. Eventually I got referred to Tanuja and her team. Tanuja not only spent enormous time to understand my situation, she and her team proactively put in lots of efforts upfront to analyse my situation and were promptly ready to suggest the right path to the resolution. I can’t thank them enough for the support, guidance and efforts to yield the smoothest outcome I could ever think of. Any NRI tax related matters - Tanuja Associates is the single source of support and i strongly recommend anyone in need for such consultation to reach out to her, to get the maximum mental peace and effective outcome! Thank you Tanuja!!

I am an OCI and wanted assistance from an Accountant conversant with the taxation rules/ repatriation of funds Re: sale of property in India/inheritance. I was referred to Tanuja by a friend and I am glad that I appointed her/ firm for the services. Outcome from every visit was positive. Throughout the process I visited her only twice/ thrice and the rest was done remotely. She guided me through the taxation rules and the best options available. She and her team assisted with the filing of the tax return and chasing Income-tax Offices as was necessary and repatriation of funds. Work was completed in a timely manner and with efficiency. I would like to thank her and her team for their professional services and have no hesitation in recommending them.

My wife and I were looking to sell our flat in Kolkata, a property we owned but had never occupied. Being residents of the USA, we were unfamiliar with the procedures involved in selling a property in India. Additionally, we hadn't completed the mutation process for the flat and lacked essential documents such as a PAN card and an Indian bank account. Furthermore, we were unfamiliar with any real estate agents in Kolkata.

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.
