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. Dr. Debashis Pal Cincinnati, Ohio

We are a couple from Toronto, Canada. In 2025, we had to sell an inherited property in Kolkata. Knowing nobody 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. From our first meeting, we found Tanuja to be extremely knowledgeable, extremely courteous and very gracious to us in every way. She proved her competency time and time again through our dealings with her over the next few months, solving every problem along the way, be it an inactive PAN card or getting a bank account opened at an Indian bank, responding to our every question and concern promptly. She guided us through the sales process and oversaw all the financial transactions like TDS, repatriating the sales proceeds, paying taxes at tax time the following year, and repatriating the tax refund. 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

Tanuja Sinha & Associates offered excellent advisory and tax/banking support for the sale of our property recently. As Dubai based NRIs, we could completely rely on Tanuja’s professional, efficient and speedy dealings to navigate complex NRI tax matters, TDS compliance and heavy documentation requirements. She engaged proactively to keep us informed of how things were moving and provided smart solutions where things were getting stuck. She is very well networked within the tax and banking ecosystem, and you can rely on her for end to end services on property sale through to repatriation of proceeds and other tax matters. Overall, Tanuja’s expertise on NRI tax matters is second to none and the ease with which she takes control over the process takes all the stress away from the customer!

There is only one word to describe the professionalism of Tanuja Sinha and Associates ("TSA"). It is Excellent. I am an NRI who has been dealing with the Indian Income Tax department for over thirty years through various tax advisers. Now that I am being advised by TSA, I have no hesitation in stating that my confidence level in their capabilities exceed all my previous experience.

I had an outstanding experience working with Tanuja Sinha & Associates, Chartered Accountants, for a complex set of requirements, including the legal formalities for a Kolkata apartment sale, bank account setup, and subsequent tax filing. Handling property transactions and financial compliance from abroad can be incredibly stressful, but Tanuja and her team including Subarna Saha made the entire process seamless. Tanuja has deep technical knowledge about cross-border compliance and provided me with invaluable advice promptly. They ensured every piece of paperwork for the property sale was flawless. Their assistance in navigating local banking procedures and managing my tax filings was prompt, structured, and entirely hassle-free. They are responsive, diligent, and true experts in their field. I highly recommend them to anyone looking for trustworthy and top-tier professional services in India!

Excellent service from Tanuja Sinha and her team. I worked closely with Subarna, who was fantastic and provided exceptional support throughout the process. Being based in the U.S., managing the paperwork and documentation required to claim a tax refund in India was challenging. Tanuja Sinha & Associates made the entire process seamless by efficiently and professionally handling all the required filings and documentation on my behalf. Their fees were transparent and reasonable, and communication was excellent throughout the process. Based on my experience, I would personally and wholeheartedly recommend Tanuja Sinha & Associates to any NRI looking for a trustworthy, dependable, and professional firm to handle their tax-related matters in India. I would have no hesitation in using their services again and would be happy to recommend them to my family, friends, and fellow NRIs.

Managing taxes as an NRI can be challenging, but Tanuja Sinha & Associates made the entire process smooth and stress-free. Their expertise in NRI taxation gave me complete confidence that everything was being handled accurately, remotely from UAE and in compliance with applicable regulations. From start to finish for my ITR filing, the experience was seamless, well-organized, and highly professional. Ms. Tanuja Sinha is approachable, dependable, and genuinely committed to helping her clients. I would also like to specifically acknowledge Mr. Subarna, who managed my case with great efficiency and demonstrated a thorough understanding of the complexities of NRI taxation and compliance requirements. I truly appreciate their responsiveness, attention to detail, and ability to handle the entire process with minimal effort required from my side. I highly recommend Tanuja Sinha & Associates to any NRI looking for a trustworthy, knowledgeable, and reliable tax consultant in India.
