Integrated Solutions for Individual and Complex Problems

The value of an integrated service provider is the quality of advice you receive and the ability to apply that comprehensive and accurate insight to your complex personal and business problems, challenges and opportunities.

It takes many entrepreneurs years to understand the inherent symbiotic relationship between tax, legal, accounting, production and employee management within any successful company or corporation.

Today’s business questions and problems are much more complex than even five years ago.

Business decisions must be made within a shorter window of opportunity when change is happening at an increasingly rapid pace.

The complications of cross-border, interstate and international business and competition has sharpened the need for accurate business insight and decision making and increased the value of an integrated business service partner who can help you through any potential opportunity or challenge.


Allen Barron’s domestic and international tax attorneys provide sound counsel on local, state, federal and international tax strategies. 


We represent clients before the IRS and state tax authorities.


Working with an experienced partner who provides comprehensive tax services is one of the basics of business and personal life.  As one of two commonly acknowledged certainties in life, taxes can be even more confusing than its counterpart, death. 


The tax services and transactional planning provided by Allen Barron remove this burden and put our clients in command of their financial decisions and prosperity.


Many individuals and businesses are unaware of their tax vulnerabilities. The tax codes change regularly and are hard to understand. 


Federal and state tax authorities can vacillate in their responses to perceived noncompliance. Some agencies have become aggressive in their regulatory and collection efforts, leaving the onus on the taxpayer to prove that he, she or it was compliant. This means you may need access to a knowledgeable tax professional you can trust.


Janathan L. Allen, APC and attorneys on staff have extensive business and corporate law expertise providing full-service legal representation and business legal services.


Our corporate law and tax attorneys have the unique ability to represent and support individuals and businesses that have simple or complex legal issues, while providing integrated services such as full service accounting, business advice and consulting, and tax expertise with the convenience and efficiency of working with one experienced firm.  


This unique single-source approach informs decisions across the spectrum of business and personal legal issues, while leveraging economies of scale.


Allen Barron’s commercial and business dispute resolution team works with individuals and business interests of all sizes to resolve matters ranging from several thousand dollars to contingent liabilities into the millions. 


We have the experience, expertise and proven legal skill to help with your matter.  We represent parties in all business lawsuits and disputes including settlement negotiations, mediation, arbitration and at trial.

& Tax Preparation

Allen Barron’s comprehensive accounting, forensic accounting and tax preparation services provide valuable support and insight to businesses and individual clients.


Business owners have many misconceptions about accounting. One is that anyone with QuickBooks can do accounting. Another is that a CPA can supply all of the expertise your company needs. Either approach can lead to costly mistakes.


How many times have you searched for someone who knows as much about your business as you do? Accounting systems are critical to successful business operations. They should capture the details of every facet of your organization, and inform critical business decisions at every stage in a company’s formation and growth.


These integrated financial systems should provide critical up-to-date information to decision making “dashboards” that provide insight at a glance to business owners and corporate management teams.


Our Business Advisory team contributes decades of C-Level experience and consulting services.


Because a multitude of risk factors and an array of competitive forces must be considered in the formation and growth of any significant business, going it alone is simply not an option. If you are to be successful in the long run, you need good strategy and sound execution.


Allen Barron, Inc. provides management advisory services to a variety of businesses, from small businesses to international corporations. Allen Barron, Inc. advises business owners and executives who serve local, regional, national and worldwide markets.
