Why Choose David M. Garvin for Tax Fraud Defense

Unique Background as a Tax Lawyer and CPA

In view of the fact that less than 1% of the licensed lawyers have won (Not Guilty on all counts) a criminal tax trial for the defense, the statistics show that there is no margin of error afforded a taxpayer who intends to go to trial in a criminal tax case and prove his or her innocence.

Tax fraud defense attorney, David M. Garvin, has shown the ability to present the taxpayer's case in a manner that takes advantage of the opportunities when presented that increase the taxpayer's chances of success. This is partially because he is a lawyer who has earned a LLM in taxation (Masters in Law) and is a CPA (Certified Public Accountant). This background provides an advantage in dealing with cases that involve tax and accounting issues.

Proven Success in the Courtroom and Tax Law Mastery

Because of his formal training and his unique abstract reasoning (top 1% on national standardized test), Mr. Garvin is able to utilize the complex concepts contained in the Internal Revenue Code to his advantage while defending his clients.  Mr. Garvin's ability to master the Internal Revenue Code's complex rules and regulations and his ability to master the courtroom during a jury trial are renown by his peers, his clients and the Courts in which he has appeared.

Other criminal lawyers in tax cases have tried to emulate Mr. Garvin's knowledge and skills by retaining a tax lawyer to conduct the jury trial with them.  Unfortunately, this only works sometimes. In these cases, the IRS agents that testify know more about the facts and the Internal Revenue Code than the criminal lawyer representing the defendant.

The IRS on direct and cross examination, realizing that the criminal lawyer does not know the Internal Revenue Code, can make statements citing the Code that the criminal lawyer does not know how to respond to.

Even if the criminal lawyer walks back to the table for the defense and asks the tax lawyer if the IRS agent is correct, the tax lawyer will not have sufficient time to explain to the criminal lawyer the technicalities to undue the damage caused by the IRS agent or the government's expert witnesses. The tax lawyer cannot conduct the cross examination because most tax lawyers have never handled a federal jury trial and are not experienced enough to conduct an effective cross examination of a trained IRS agent.

Other Not Guilty Verdicts in Non-tax Cases.

Mr. Garvin has also obtained not guilty verdicts in a number of his cases for clients who were not indicted for alleged tax violations but were indicted for other white collar (economic) crimes.

A Successful Tax Fraud Lawyer Knows That a Defense Solely Based upon Willfulness Is a Defense of Last Resort

When you are the target of an IRS criminal investigation, retaining a tax fraud lawyer who has gone to trial in numerous criminal tax cases and has obtained complete acquittals (Not Guilty Verdicts on All Counts) is imperative.

There are a lot of competent tax attorneys that have no concept of how to try a federal criminal trial. Likewise, many skilled criminal lawyers know how to try a case but do not know the tax laws. When a taxpayer hires these lawyers, they often limit their defense of the taxpayer to the issue of willfulness.

This routinely results in the defense lawyer recommending that the client accept a plea agreement requiring the taxpayer to plead guilty to a felony.  An experienced successful tax fraud lawyer knows that a defense based solely upon willfulness is a defense of last resort and is seldom sufficient to achieve not-guilty verdicts on all counts.   

When Winning Means Everything

The Selection of an Experienced Winning Tax Fraud Lawyer is Crucial

Some taxpayers look at the statistics and become overwhelmed with the feeling that maintaining their innocence is futile and obtaining justice from a jury trial is hopeless. Fortunately, some taxpayers have the fortitude to go to trial to prove their innocence and share the spirit of the late great Winston Churchill, who found himself and his country under siege and once said:

“Now, this is not the end.  It is not even the beginning of the end. But it is, perhaps, the end of the beginning.”

-- Winston Churchill

The course of history was influenced, and the free world was saved by persons of similar courage in the face of overwhelming odds.  In the context of a criminal tax case, when winning means everything, the selection of an experienced winning tax fraud lawyer is crucial. The fortitude of the client to fight for a just outcome is also a necessary ingredient to a successful defense. This situation often leads taxpayers to proclaim: "Winning is the Only Option." This is not the end, but it is time to begin.

Taxpayers Should Use Their Common Sense

There is no substitute for common sense.  If you ask the average person the following questions, they almost unanimously give the following answers.

If you needed heart surgery, would you hire a doctor who had never successfully performed heart surgery before to perform your surgery?

​​​​If you needed to build a house, would you hire a contractor who had never successfully built a house before to build your house?

If you needed a pilot to fly you to a meeting, would you hire a pilot who had never successfully flown an airplane to fly you to your appointment?

These common-sense answers beg the question:

“Why would you hire a lawyer who has never won a criminal tax trial for the defense, to defend you in a criminal tax investigation or trial?”

You have the absolute right when selecting a lawyer to ask for the names of the cases and the case numbers of the cases which resulted in Not Guilty on all count's verdicts.

Do your homework as if your liberty depends upon it because it may!
