California Tax Crimes Lawyer

A California tax crimes lawyer becomes essential when you face criminal tax fraud charges that could result in years of imprisonment and financial ruin. Kenney Legal Defense brings over 30 years of experience defending clients against tax evasion and other criminal tax charges brought by both federal and state authorities.

Attorney Karren Kenney, a Certified Fraud Examiner and former Senior Deputy Public Defender, understands the complex intersection of tax law and criminal defense needed to protect you from aggressive prosecution.

Our criminal tax defense attorney team has successfully defended business owners, professionals, and individuals facing investigation by the Internal Revenue Service (IRS) and California tax authorities.

Our California Tax Crimes Lawyer Protects You from Criminal Tax Prosecution

Our California Tax Crimes Lawyer Protects You from Criminal Tax Prosecution

Criminal tax cases differ fundamentally from civil tax disputes, carrying the threat of imprisonment rather than just financial penalties and interest. The IRS Criminal Investigation Division and California Franchise Tax Board pursue these cases aggressively, seeking to make examples of taxpayers they believe intentionally violated tax laws. Our criminal defense attorney recognizes that many tax issues arise from honest mistakes, poor recordkeeping, or reliance on bad advice rather than criminal intent.

Tax authorities often blur the line between civil and criminal matters, using tax audits to gather evidence for criminal prosecution while taxpayers believe they're cooperating with routine examinations. Federal prosecutors work closely with IRS special agents to build cases over years, analyzing financial records and conducting surveillance before filing charges. Our tax attorney knows how to navigate both civil and criminal proceedings, protecting your rights while working to resolve tax liability issues without criminal consequences.

Tax Crime Cases Our California Tax Crimes Attorney Handles

Tax crimes encompass various violations of federal and state tax laws, from simple failure to file returns to sophisticated schemes involving offshore accounts and false documentation. Our defense lawyer has successfully defended clients facing all types of criminal tax charges, understanding the technical requirements prosecutors must prove. We work with forensic accountants and tax lawyers to challenge the government's calculations and interpretations of complex tax regulations.

Tax Evasion

Tax evasion involves willfully attempting to evade or defeat tax obligations through affirmative acts of concealment or misrepresentation, carrying penalties up to five years in federal prison under 26 U.S.C. § 7201. Criminal tax evasion requires proof of substantial tax liability, willfulness, and affirmative acts beyond mere failure to pay, such as hiding assets or using false identities. The government must prove you knew about the tax obligation and intentionally took steps to avoid it, not just that you owed taxes. Our defense strategies include demonstrating good faith belief that business or income tax positions were correct, showing reliance on professional advice, or proving that actions (such as underreporting income) were negligent rather than willful.

Tax Fraud

Criminal tax fraud encompasses various schemes to defraud the government through false statements, fake documents, or concealment of income, with penalties including three years imprisonment for each false return. The California Tax and Fee Administration and IRS pursue fraud cases involving unreported income, fictitious deductions, or false exemptions claimed on returns. Unlike civil fraud penalty proceedings that only require clear and convincing evidence, criminal fraud requires proof beyond a reasonable doubt. We challenge the government's evidence of willfulness, demonstrate legitimate business purposes for questioned transactions, and show that errors resulted from complexity rather than fraudulent intent. Count on us to fight your tax fraud case.

Failure to File Returns

Willful failure to file tax returns constitutes a misdemeanor under federal law, but can support felony tax evasion charges when combined with affirmative acts to conceal income or assets. Each year of non-filing represents a separate criminal count, potentially resulting in multiple years of imprisonment for chronic non-filers. The government must prove you had a legal obligation to file, knew about it, and willfully failed to comply. Our fraud defense approach includes demonstrating reasonable cause for non-filing, such as serious illness, reliance on professionals who failed to file, or good faith belief that no filing requirement existed.

Employment Tax Violations

Employment tax crimes involve failing to collect, account for, or pay over payroll taxes withheld from employees' wages, often called "trust fund" violations. Business owners and responsible persons face personal criminal liability for willfully failing to pay employment taxes, with penalties including five years imprisonment. These cases often arise during business financial distress when owners use tax money to pay other creditors, creating criminal liability. We demonstrate a lack of willfulness by showing financial impossibility, reasonable prioritization of limited funds, or that clients weren't responsible persons with authority over tax payments.

Sales Tax Fraud

Sales tax fraud involves collecting taxes from customers but failing to remit them to tax authorities, filing false sales tax returns, or operating without required permits. California aggressively prosecutes sales tax violations, especially in cash-intensive businesses like restaurants, retail stores, and service providers. Criminal charges require proving intentional fraud rather than negligent underpayment or calculation errors. Our defense involves analyzing point-of-sale systems, demonstrating legitimate business explanations for discrepancies, and showing that any underpayment was unintentional.

False Tax Returns

Filing false tax returns under 26 U.S.C. § 7206 includes making false statements, assisting others in filing false returns, or submitting documents known to be fraudulent. Each false return or document constitutes a separate felony punishable by three years in prison and substantial fines. Prosecutors must prove you knew statements were false and acted willfully, not just that returns contained errors. We examine whether alleged false statements were actually incorrect, whether you knew about inaccuracies, and whether you reasonably relied on information provided by others.

Money Laundering Through Tax Crimes

Tax crimes often accompany money laundering charges when prosecutors allege criminals used tax fraud to disguise illegal income or clean dirty money through fraudulent refunds. These complex cases involve multiple agencies and can trigger sentences exceeding 20 years when tax and money laundering charges combine. The government must prove both the underlying criminal activity generating funds and subsequent tax crimes to launder proceeds. Our wire fraud and conspiracy defense experience helps us challenge these complex prosecutions.

Cryptocurrency Tax Crimes

Cryptocurrency tax enforcement has become a priority, with criminal charges for failing to report crypto transactions, concealing digital assets, or using cryptocurrency to evade taxes. The IRS uses blockchain analysis and exchange subpoenas to identify unreported cryptocurrency gains and offshore holdings. These cases involve complex technical and legal issues about when taxable events occur and how to value digital assets. We work with cryptocurrency experts to challenge the government's analysis and demonstrate good faith attempts to comply with unclear regulations.

Steps to Take When Facing Tax Crime Investigation

Steps to Take When Facing a Tax Crime Investigation
  1. Stop all communication with tax authorities immediately and retain a criminal tax defense attorney before responding to any inquiries. Anything you say to IRS agents or state tax officials can become evidence against you, even seemingly innocent explanations.
  2. Preserve all tax records, financial documents, and communications with tax preparers or advisors. Destroying documents after learning of an investigation constitutes obstruction of justice, adding serious criminal charges regardless of underlying tax issues.
  3. Do not attempt to file amended returns or make payments without legal counsel. While correcting past mistakes might seem logical, these actions can be interpreted as admissions of prior wrongdoing.
  4. Identify and secure all professional advice you received regarding tax positions under investigation. Reliance on tax professionals provides important defenses, but only if you can document the advice received and information provided.
  5. Review your financial accounts and assets for any actions that might appear as concealment or structuring. Moving money or closing accounts during investigations can transform civil matters into criminal cases.
  6. Prepare for potential civil penalties while fighting criminal charges. Even if criminal charges are defeated, civil tax liability continues, requiring coordinated defense strategies.
  7. Avoid discussing your tax situation with anyone except your attorney. Conversations with friends, family, or business associates aren't privileged, and these people can be forced to testify against you.

Defense Strategies for Tax Crime Cases

  • Willfulness challenges form the cornerstone of criminal tax defense since prosecutors must prove intentional violation of known legal duties. We demonstrate good faith belief in tax positions, complexity creating reasonable disagreement, or reliance on professional advice negating criminal intent.
  • Technical defenses based on tax law complexity often defeat criminal charges. Tax regulations are notoriously complex, and legitimate disagreements about interpretations don't constitute crimes even if positions are ultimately incorrect.
  • Voluntary disclosure before investigation begins can prevent criminal prosecution. We evaluate eligibility for IRS and California voluntary disclosure programs that impose civil penalties but avoid criminal charges.
  • Mental state defenses apply when addiction, mental illness, or cognitive impairment affected tax compliance. These conditions can negate the willfulness required for a criminal conviction while explaining non-compliance.
  • Statute of limitations defenses bar prosecution for older tax years. Generally, criminal tax charges must be filed within six years, though certain acts can extend limitations periods, according to IRS procedures.

When Tax Charges Can Be Avoided or Dismissed

When Tax Charges Can Be Avoided or Dismissed

Tax charges can be avoided through voluntary disclosure programs when taxpayers correct non-compliance before criminal investigations begin. The IRS voluntary disclosure practice and California's program offer paths to resolve tax liability without criminal prosecution for eligible taxpayers. Our tax attorneys evaluate qualifications and guide clients through disclosure processes that prevent criminal charges while minimizing civil penalties.

Dismissal becomes possible when prosecutors cannot prove willfulness, when investigations reveal only civil violations, or when constitutional violations taint evidence. Tax authorities sometimes overreach, transforming civil disputes into criminal cases without sufficient evidence of intentional wrongdoing. We file aggressive motions challenging indictments, seeking suppression of illegally obtained evidence, and demonstrating that conduct was at most negligent rather than criminal. If you are facing a potential criminal tax issue, count on our team to help you.

When Resolving Tax Cases Through Negotiation Works

Negotiation often provides better outcomes than trial when some tax liability exists, but criminal prosecution seems excessive for the conduct involved. Prosecutors may agree to let defendants pay tax liability and civil penalties without a criminal conviction when cases involve first-time offenders or sympathetic circumstances. Our extensive experience helps evaluate whether plea offers appropriately reflect case weaknesses and whether better terms are obtainable.

The government's interest in collecting revenue sometimes outweighs the desire for criminal convictions, especially when defendants can pay substantial tax liability. We negotiate global resolutions addressing both criminal charges and civil tax obligations, structuring agreements that avoid imprisonment while resolving all tax issues. These negotiations require careful coordination between criminal and civil proceedings to ensure a comprehensive resolution.

When Taking Tax Cases to Trial Is Necessary

When Taking Tax Cases to Trial Is Necessary

Trial becomes necessary when you're innocent, when the government's theory criminalizes legitimate tax positions, or when plea offers essentially equal trial risks. Our trial experience, including over 100 jury trials, provides the skills needed to present complex tax defenses effectively. Federal crimes involving taxation require careful jury education about tax law complexity and the difference between mistakes and crimes.

Some tax prosecutions rest on aggressive interpretations that criminalize common business practices or reasonable tax positions. Juries often sympathize with taxpayers facing imprisonment for complex regulatory violations, especially when evidence shows good faith attempts at compliance. We present compelling narratives explaining how tax positions were reasonable, why mistakes occurred, and why criminal punishment is inappropriate.

FAQs

What's the difference between criminal and civil tax violations?

Criminal tax violations require willful intent to violate tax laws and can result in imprisonment, while civil violations only impose financial penalties. The IRS decides whether to pursue criminal charges based on factors including amount, duration, and sophistication of violations.

Can I go to jail for not paying taxes?

Simply owing taxes isn't criminal, but willfully evading tax obligations through affirmative acts like hiding assets or filing false returns can result in imprisonment. The government must prove intentional evasion, not just inability to pay.

Should I talk to IRS agents who contact me?

Never speak with IRS Criminal Investigation agents without an attorney present, as anything you say can be used against you. According to IRS procedures, special agents must advise you of your rights before custodial interrogation.

What triggers criminal tax investigations?

Criminal investigations often begin from civil audits, information returns, whistleblower reports, or financial institution suspicious activity reports. Large unreported income, consistent patterns of non-compliance, or badges of fraud during civil examinations can trigger criminal referrals.

Can old tax problems lead to criminal charges?

Generally, criminal tax charges must be filed within six years of the violation, though some acts can extend this period. The Department of Justice Tax Division considers various factors, including the age of violations, when deciding whether to prosecute.
