As a realtor, I want to sell houses.  I know that seems obvious, but when you are self-employed, you can spend hours doing tasks that get your no net income. All my activities should be generating income activities, or I am spinning wheels. 

I set out on a search for a book keeper. What did I end up with, you ask? 

Jason Osser. 

Jason is so much more than a book keeper. Jason is my business consultant who just happens to be proficient in QuickBooks AND is a CPA. How does it get any better? Well, Jason helps. He sees the big picture. He understands how to not only create a business budget, helping with projections and forecasting, but he also helps with the analysis of what I call “subject,” “verb,” and “predicate,”—my income, expenses and net cash flow. His look at my financial statements monthly has helped, and continues to help, nurture that framework for success for me as a person, who rarely sits down and is driven with a goal in mind.

Jason sees a problem and can fix it with a couple of subtle questions, allowing me to derive the answers. As a person who has bought and sold a couple of businesses himself, and also grown bottom lines through expense cutting, Jason is not a clairvoyant. He is experienced, savvy and a back-to-basics businessman. He is on my side, and that makes me better at what I do each and every day. 

My business has grown from $30 million per year to $50 million per year in volume, in 365 days! WOW. We’re doing lots right with Team LizLuke.  Jason’s a player on my team. I would recommend he join yours too!

I used Jason for my 2009 taxes and was very impressed! The process was extremely painless and I enjoyed the time I spent with him. Jason found $300 that I never would have known about if had done my taxes myself, which is what I have always done in the past. You can bet I’ll be using Jason from now on and I’m referring him to others! His top qualities are: great results, expertise and good value for the money.

Jason Osser has been instrumental in helping me organize my business books and helping me reach the next level with my interior design business. His bookkeeping services have kept me clear on where I am financially and have allowed me to plan for where I need to go. I highly recommend Jason to any business that wants a clear financial picture for their business.

Thanks Jason.

Our law firm start-up needed to focus on practicing law and solving public policy problems for our clients. Lawyers managing their books? A sure recipe for disaster.

We interviewed many companies - large and small - before we signed up with Jason. We are really pleased with his services and advice. Jason is patient and understands the accounting needs of a start-up company. He is an invaluable member of the Poblete Tamargo team; we wholeheartedly recommend him and his company.

I have been working with Jason Osser for 4 years. During that time, Jason has gone above and beyond in extending himself to solving a variety of tax issues that had been plaguing me for some time. Jason helped me to organize my thinking and documentation in a step by step orderly way that resulted in totally resolving my issues with both the IRS and the Virginia taxing authorities with a very favorable outcome. I could not be more pleased with Jason Osser’s ability to listen to his client’s issues and apply his professional knowledge. I whole heartily recommend Jason S Osser CPA & Associates to anyone who needs help with tax preparation or who is having issues with the IRS.


I started working with Jason in 2012 on filing of both my business and personal tax returns; over the years, Jason has also become my "go to" person for all my business accounting needs. Understanding my unique situation, Jason advised me regarding proper setup of my business entity, assisted in keeping my accounting records up to date, and has recently helped my business secure a line of credit. What I am most appreciative of Jason is his responsiveness and tenacity for getting results. I know I can always count on Jason's accounting expertise so that I can focus on running my business.
