Having run my own accounting and consulting firm for over a decade, I have had substantial exposure to handling LLC finances and back tax filings. I have, in fact, aided numerous businesses with similar requirements to yours and successfully carried out over 400 Income Tax Returns. In addition, as a Certified QuickBooks Pro Advisor, I am proficient in using various accounting software including QuickBooks (which you mentioned you use) which will make the process even smoother.
My experience extends beyond physical borders; I have worked with clients in multiple countries including the US, UK, UAE, Singapore, India and Australia gaining insights into their respective tax laws which I can leverage for your project.
Moreover, good communication is at the heart of my work philosophy - it's important that complex financial issues are explained lucidly to help clients understand and be part of the decision-making process. In this regard, being a Chartered Accountant having both the CPA and ACCA equivalent credentials offers me an edge. Lastly but importantly, I understand that time-efficiency is key to your project; I am committed to delivering a quick turnaround but without compromising on accuracy and quality. Let's ensure your LLC catches up with its tax filing obligations seamlessly.
