Individual & Business Tax Services

At Brenner & Elsea-Mandojana, LLC, our vast U.S. and overseas experience allows us to recognize the complex needs of our individual and business tax clients no matter where they are located. Because we recognize the broad needs of our US-based and overseas clients, we provide a large array of services and U.S. tax expertise to meet those needs.

Our individual tax services focus on the needs of U.S.-based individuals and U.S. expatriate communities worldwide. Our business tax services similarly focus on the tax planning and filing needs of our U.S.-based and overseas small and medium-size business clients.



Expatriate Tax Services

U.S. expatriates face a variety of unique tax and financial planning issues. Unlike many countries, the U.S. imposes worldwide taxation on its citizens and U.S. green card holders.

At Brenner & Elsea-Mandojana, LLC, we specialize in U.S. tax law and financial planning issues as they relate to the unique lifestyle and challenges faced by U.S. expats. Both Jim Brenner and Christine Elsea-Mandojana have hands-on experience in the U.S. expatriate life and understand the resulting tax complexities.

Personal Financial Planning
There are steps you can take to secure your financial future. Ensuring you have an adequate emergency fund, reassessing your retirement goals and progress, and planning for college are just a few of the steps you should take now.

Brenner & Elsea-Mandojana, LLC offers financial planning services tailored to the needs of U.S. individuals located in the U.S. and overseas.

Business Valuations
Determining the value of a business, asset or ownership right, requires a great deal of experience, financial knowledge and judgment.  Valuation has evolved into three basic approaches, each with many methods or techniques.  Because of the many subjective factors involved with applying the many methods and techniques, persons performing the valuation process often arrive at significantly different conclusions.  As CPA’s accredited in business valuations,  we meet these requirements.


Accounting, Litigation Support and General Advisory


Acquisitions & Divestitures, Accounting & Attestation, General Advisory, Quick Books, SEC Compliance & Reporting

General Advisory
With numerous, constantly changing rules and regulations to follow, projects to complete and deadlines to meet, persons responsible for the finance, tax and accounting functions need resources.  Further, many growing small- and mid-sized business do not need and cannot afford in-house, full-time, senior level finance executives.  That’s where we fit in.  Our experiences, resources (knowledge, qualified people, tools and systems) and commitment, will get the project done right.  Our practice is dedicated to outstanding and timely service.


​Accounting & Attestation
We specialize in finance and accounting operations, and transformation of those operations as companies grow. Streamlining the numbers gathering and the closing process, then creating financial pictures that help articulate the story behind the numbers, is what we do. Whether you are a business owner, financial officer or professional service provider, we can assist you with controllership functions and other finance projects.
