Resolve Your Legal Tax & Accounting Challenges

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.

Founder, Allen Barron, Inc.

Janathan Allen is an experienced tax attorney and business lawyer who integrates business, legal, tax and accounting strategies to provide her clients with better answers to their questions and more informed strategies to leverage their opportunities.

Most businesses have separate tax attorneys, business attorneys, CPAs and accountants, tax preparers and financial advisors. If you take the same problem to each professional, they will provide what they genuinely believe is the right and best answer. However, it will only be based upon their unique (and somewhat limited) perspective.

The business attorney will have no idea how the solution they are recommending impacts business operations or your accounting systems. The financial planner has no idea how their recommendation may be impacted by interstate or international tax implications.

This is the genuine value of the integrated approach Janathan Allen and Allen Barron take when they work with you as a client on any challenge or opportunity.

Allen Barron’s legal services are provided by Janathan L. Allen, APC.

Now that President Joe Biden has signed his $1.9 trillion pandemic relief package into law, some people could receive stimulus checks as early as the March 13-14 weekend. That puts the rollout smack in the middle of tax season. Why does that matter? Well, the timing of your 2020 tax return could make all the difference between getting the full $1,400 (or even more) and getting nothing. Here’s what you should know as you file your tax return, plus a few tips to help your tax refund arrive on time this year.

Testimonials

Dealing with our firm’s taxes always seemed a stressful and cumbersome task. With Allen Barron preparing our tax returns, we have peace of mind knowing that Jan and her team are thorough, precise and competent, that our data is handled securely, and that her firm is constantly vigilant of ever changing tax laws that impact tax liabilities – both for our partners and our firm - so we can focus on what really matters to us – our company and our clients.
I was referred to Janathan Allen by a fellow friend and colleague. I was unsure how a transactional plan or a corporate election for my new business venture could make a difference. I had questions, lots of them…and Jan had answers. But the one we all ask ourselves is, would her firm be worth the money? Today, I can confirm that it was. That transactional plan led to entity creation and corporate governance, estate planning, and a trusted adviser. Money well spent, and as Jan so aptly states, “an integrated single source of guidance.” All under one roof.
When an employment opportunity in an engineering firm opened up for me in the United States, I took it and never looked back. Leaving my foreign bank investments intact in my native country, I collected foreign earnings for a few years. Then I learned that I should have been filing voluntary disclosures of foreign accounts – or “FBAR’s” – when I immigrated to the USA. Janathan L. Allen, APC helped me to fulfill the disclosure requirements, provided me with options, and outlined a course of action for yearly filing that has kept me in compliance with the US Dept of Treasury and provided a solution before it became a problem.
COVID-19 hit my business hard. It all happened so fast. One minute my business was open, the next day it wasn’t. But life keeps moving, and so did I. I reached out to Allen Barron, Inc., who’d been doing my taxes for years. What next? Jan provided me with some business advice to help me navigate through these unprecedented times, and has been a steadfast advisor, working with me to dissolve the company, file final tax returns, and keeping me in compliance with tax authorities. It’s been a rough ride and tough year, but with Allen Barron by my side, I know that when I start my new business venture, I’ll get great advice and exciting results!
I have been working with Allen Barron for over 16 years. Janathan is one of the most knowledgeable and practical Attorneys I have worked with. Her commonsense approach to my companies’ tax and legal matters is only eclipsed by her experience dealing with real world situations. Ms. Allen is thorough, reliable and a pleasure to work with.
