"Reliable accounting services, supportive team, and efficient business solutions for entrepreneurs."
Lancaster provided a legitimate avenue for me to leave my 9 to 5 job and start my own business. The opening of bank account, EP application, accounting and taxation were well handled through this team. I am now my own boss and I have a team to thank for assisting me on that journey. Trustworthy, reliable, and responsive; I have since recommended him to many of my peers who wanted to pursue their own business as well.

I highly recommend Emilia and her team at One Tax CM to anyone looking for a corp sec team. Our company has been incorporated in Singapore for several years and gone through 2 other corporate sec companies and have been dissatisfied with their lack of response, high turnover rate of staff and thus creating redundant work and email responses on my end, and inexperience which causes recommendations that are not ideal for my company's situation.
One Tax CM solves all these problems. With a dedicated team, you have quick responses even after work hours and strong connections in Singapore that can recommend leaders in different industries that I need.
In the world of corporate secretaries, if you're looking for the cheapest services, you will also get the quality you pay for. While One Tax CM is not the cheapest, they are also far from the most expensive but you'll get the best value here.
