Tax Fraud & Evasion Defense Lawyers
Under investigation by the Arizona Department of Revenue or the IRS, or charged with tax fraud or evasion (A.R.S. § 42-1127)? These cases turn on willfulness, the State or the government must prove you intended to evade, not that you made a mistake or relied on a preparer. An audit can quietly become a criminal case. Do not talk to a revenue agent or sign anything before you speak with a defense lawyer.

What Is Tax Fraud and Tax Evasion in Arizona?
Quick answer: Criminal tax violations under A.R.S. § 42-1127 include willfully failing to file, filing a false return, or attempting to evade a tax, most are Class 5 felonies, and conduct by a return preparer or involving larger schemes can rise higher. Collected-but-unremitted transaction privilege (sales) tax is held in trust and can be charged as theft (A.R.S. § 13-1802). The same conduct is often charged as fraudulent schemes (A.R.S. § 13-2310), a Class 2 felony, and federally under 26 U.S.C. § 7201 (evasion) or § 7206 (false returns). The decisive element is willfulness, an honest mistake, a good-faith position, or reasonable reliance on an accountant is a defense.

If you’ve been charged with tax fraud in Arizona, you probably have urgent questions about what you’re facing and what comes next. Here are straight answers to the questions people ask most, with a plain-English breakdown of the law under A.R.S. § 42-1127, the penalties, and the defenses that matter most.
Is tax fraud a felony in Arizona?
Yes. Criminal tax violations under A.R.S. § 42-1127 — willful failure to file, filing a false return, or evasion — are generally Class 5 felonies. The same conduct is frequently also charged as fraudulent schemes (A.R.S. § 13-2310), a Class 2 felony, which carries much higher exposure than the tax statute itself.
How much prison time does tax fraud carry in Arizona?
A standalone Class 5 tax crime under A.R.S. § 42-1127 carries roughly 6 months to 2.5 years for a first offense and is often probation-eligible. Trust-fund theft of unremitted sales tax or a stacked fraudulent-schemes count can raise the range to about 3 to 12.5 years, and federal evasion under 26 U.S.C. § 7201 adds up to 5 years per count.
What is the difference between tax fraud and an honest mistake?
Willfulness. Tax crimes require a voluntary, intentional violation of a known legal duty, so an honest mistake, a misunderstanding of the law, or negligence is not a crime — it is a civil matter. Good-faith reliance on a qualified accountant or preparer, with full disclosure, also negates willfulness and is one of the strongest defenses.
Can you go to jail for not paying sales tax in Arizona?
Potentially. Transaction privilege (sales) tax you collect is held in trust for the State, so collecting it but not remitting it can be charged as theft under A.R.S. § 13-1802, graded by the dollar amount up to a Class 2 felony. Establishing the true unremitted amount and any good-faith dispute is central, and paying it back is powerful mitigation.
Can paying the tax make a tax fraud case go away?
Sometimes. Full payment of the tax, penalties, interest, and restitution is the single most effective mitigation in a tax case, because the State and the IRS care about collection. Presented early alongside a willfulness defense, a credible payment can support a civil resolution instead of a criminal charge, especially for a first-time case.
Will a tax fraud conviction affect my professional license?
Likely. A tax-fraud felony is a crime of dishonesty that can trigger discipline for CPAs, real estate agents, and finance professionals, and a TPT case can threaten a business’s license. A conviction also brings a permanent record, civil fraud penalties and interest, loss of civil and firearm rights, and immigration consequences for non-citizens.
How the Charge Sets the Tax-Crime Exposure
Arizona tax crimes are usually Class 5 felonies, but trust-fund theft and fraudulent-schemes counts charged alongside them carry far higher exposure.
| Statute | Conduct | Class / Penalty | First-Offense Range* |
|---|---|---|---|
| A.R.S. § 42-1127 | False return / failure to file / evasion | Class 5 Felony | 6 mo – 2.5 years |
| A.R.S. § 13-1802 | Unremitted TPT (trust-fund theft) | Class 6–2 | By dollar amount |
| A.R.S. § 13-2310 | Tax scheme to defraud | Class 2 Felony | 3 – 12.5 years |
| 26 U.S.C. § 7201 | Federal tax evasion | Felony | Up to 5 yrs/count |
| 26 U.S.C. § 7206 | Federal false return | Felony | Up to 3 yrs/count |
*State ranges are for a first offense and vary with priors and aggravators. Federal sentences are driven by the tax loss under the Sentencing Guidelines.
What the State Must Prove for Tax Fraud
To convict you of Tax Fraud under A.R.S. § 42-1127, the prosecutor must prove every one of these elements beyond a reasonable doubt. If even one fails, the charge fails.
- 1A tax was due and owing. There was an actual tax obligation, sometimes itself disputable on the merits.
- 2An affirmative act or omission. You filed a false return, failed to file, or took a step to evade or conceal.
- 3Willfulness. You acted willfully, a voluntary, intentional violation of a known duty, the decisive, most-contested element.
- 4Intent to evade or defraud. The act was done to evade tax or obtain a benefit, not by mistake or good-faith error.
Examples of Conduct Charged as Tax Fraud
- Underreporting income or inflating deductions on a return
- Failing to file returns over multiple years with income earned
- Collecting sales tax (TPT) from customers but not remitting it
- Claiming false or inflated refunds
- Keeping two sets of books or hiding income in undisclosed accounts
What Sentence Could You Actually Face?
Standalone Arizona tax crimes are probation-available Class 5 felonies, but trust-fund theft, fraudulent-schemes counts, and parallel federal charges can push exposure to over a decade. Paying the tax, penalties, and restitution remains a powerful tool.

⚠ Paying the Tax Changes the Case
In tax cases, full payment of the tax, penalties, and interest, plus restitution, is often the single most effective mitigation, and sometimes the difference between a criminal charge and a civil resolution. The State and the IRS care about collection. A credible payment plan presented early, with the willfulness defense, can keep a first-time case out of prison, and sometimes out of court.
How We Fight Arizona Tax Fraud Cases
Every case has weak points. These are the defenses we look at first.
Attacking Willfulness & Intent
No Willfulness. Tax crimes require an intentional violation of a known duty. An honest mistake, a misunderstanding of the law, or negligence is not willful, and is not a crime.
Reliance on a Professional. Good-faith reliance on an accountant or tax preparer, with full disclosure, negates willfulness.
A Good-Faith Position. A reasonable, good-faith tax position, even if ultimately wrong, is a civil dispute, not criminal fraud.
It’s a Civil Matter. Many cases belong in the civil audit and collection process, not a criminal courtroom; we work to keep them there.
Attacking the Evidence & Process
Disputing the Tax Loss. The State’s loss figure is frequently inflated. Our forensic accountant re-computes the true liability, which drives both charging and sentencing.
Statements in the Audit. Statements obtained without proper warnings, or beyond the civil scope, can be challenged.
Unlawful Search of Records. Books, devices, and accounts seized without proper process can be suppressed.
Statute of Limitations. Older tax years may fall outside the limitations period and cannot be charged.
The Experts We Bring to the Table
The State builds financial-crime cases with investigators, forensic auditors, and data analysts. We answer with the same caliber of specialists.
Forensic Accountants
Following the Money
Independently trace transactions, audit the State’s spreadsheets, and expose double-counting, missing context, and innocent explanations.
Certified Fraud Examiners
Intent & Scheme Analysis
Evaluate whether the conduct actually fits the charge or is an ordinary business dispute, and where the intent evidence falls short.
Computer Forensics Experts
Devices & Accounts
Examine the digital evidence, emails, logins, and IP data, and challenge whether it really proves who acted.
Financial & Data Analysts
Records & Patterns
Reconstruct the financial record from bank and accounting data and test the assumptions behind the State’s loss calculations.
Tax & Regulatory Experts
Compliance & Reporting
Explain industry practice, reporting rules, and tax treatment that the State has mischaracterized as a crime.
Valuation & Restitution Experts
Loss & Restitution
Establish the true loss amount, often far lower than alleged, which drives both the felony class and any restitution.

Arizona Tax Fraud FAQs
Quick answers to the questions we hear most about tax fraud charges, penalties, and defenses in Arizona.
Is tax fraud a felony in Arizona?
Yes. Criminal tax violations under A.R.S. 42-1127, willful failure to file, false returns, or evasion, are generally Class 5 felonies. The same conduct is often also charged as fraudulent schemes (A.R.S. 13-2310), a Class 2 felony.
What is the difference between tax fraud and a mistake?
Willfulness. Tax crimes require a voluntary, intentional violation of a known legal duty. An honest mistake, a misunderstanding, or negligence is not a crime, it is a civil matter. Proving the absence of willfulness is the core defense.
Can I go to jail for not paying sales tax?
Potentially. Sales tax (TPT) you collect is held in trust for the State, so collecting it but not remitting it can be charged as theft (A.R.S. 13-1802), graded by amount up to a Class 2 felony. Paying it back is powerful mitigation.
When does a tax audit become criminal?
Usually when an auditor shifts from verifying numbers to probing intent, or refers the case to ADOR’s criminal unit or IRS-CI. If that happens, stop talking and get counsel, statements from the civil phase build the criminal case.
Can the State and the IRS both charge me?
Yes. Arizona (ADOR) and the federal government (IRS-CI) can pursue parallel cases for the same conduct. Federal evasion (26 U.S.C. 7201) carries up to five years per count. We assess and coordinate both fronts.
Is relying on my accountant a defense?
Often, yes. Good-faith reliance on a qualified preparer or accountant, with full and honest disclosure, negates the willfulness element. We document that reliance to defeat the intent the State must prove.
Can paying the tax make the case go away?
Sometimes. Full payment of the tax, penalties, interest, and restitution is the strongest mitigation in a tax case and can support a civil resolution instead of a criminal charge, especially for a first-time case. Earlier is better.
What is the penalty for federal tax evasion?
Federal tax evasion under 26 U.S.C. 7201 carries up to five years in prison per count plus heavy fines, with the sentence driven by the tax loss under the Sentencing Guidelines. Filing a false return (7206) carries up to three years.
Will a tax conviction affect my professional license?
Likely. A tax-fraud conviction is a crime of dishonesty that can trigger discipline for CPAs, real estate agents, and finance professionals, and can threaten a business’s TPT license. Protecting your record is often as important as avoiding jail.
How far back can they charge me?
It depends on the statute and whether conduct was ongoing. Older tax years may fall outside the limitations period and cannot be charged, which can be a complete defense to part of a case.
Will I get a real attorney or a junior associate?
At many large firms the name on the door is a marketing figurehead and your case goes to a rotating associate. At Tamou Law Group your defense is handled by a full team of experienced attorneys, not associates, including founding attorney Michael Tamou. Call 623-321-4699, 24/7.
