California businesses do not own the sales-and-use tax they collect; they act as trustees for the state. File or pay late, pocket the tax, or understate taxable sales and the California Department of Tax and Fee Administration (CDTFA) will unleash a cascade of civil and criminal tax penalties that can gut your working capital, pierce the corporate veil, and—in egregious cases—put you behind bars. Understanding those penalties and acting before the CDTFA decides your conduct was intentional is the first step in meaningful damage control.
California’s sales tax regulations are notoriously intricate, and failing to comply can lead to significant legal and financial fallout. Whether your small business is currently undergoing a sales tax audit, challenging a completed audit’s findings, or at risk of being targeted for a criminal tax investigation, it is essential to act promptly by consulting an experienced dual-licensed CDTFA Tax Attorney & CPA. A well‐crafted and timely response can make all the difference in reducing fines and preventing criminal tax prosecution.

The Civil Penalty Cascade
The CDTFA’s surcharge structure is cumulative—one misstep can trigger several add-ons, all of which accrue interest until paid:
- 10 % Late-Filing / Late-Payment Penalty – Slapped on the moment a return or payment is late.
- 6 % Late Pre-Payment Penalty – Quarterly filers that miss the mid-quarter pre-payment owe an extra six percent.
- 10 % EFT Penalty – Ordered to pay electronically but mail a check instead? Add another ten percent.
- 25 % Civil Fraud Penalty – Applied when any portion of a deficiency stems from fraud or an intent to evade. Note: if they have the evidence to assert this penalty, they have the evidence to criminally prosecute.
- 40 % “Collected-But-Not-Remitted” Penalty – When you knowingly keep tax you collected from customers, the state adds a punishing forty percent overlay.
- Collection-Cost Recovery Fee & Interest – Balances unpaid for 90 days draw a flat collection fee plus interest that compounds quarterly.
A retailer that files late, under-states sales, and pockets the tax can face penalties totaling 75 % of the tax due—before interest and fees begin to snowball.
CDTFA’s Collection Arsenal: Liens, Levies, and License Revocations
If you fail to resolve the balance, the CDTFA shifts from assessment to enforcement. Its powers are sweeping:
- Liens & Levies – Real estate, equipment, bank accounts, wages, and even state-tax refunds are fair game.
- Civil Warrants (“Till-Tap” and “Keeper” Warrants) – CDTFA agents, escorted by local law enforcement, can empty your cash register on the spot or station a keeper inside your business for up to ten days to seize every incoming dollar.
- Notice to Withhold (Form CDTFA-465) – Freezes a taxpayer’s assets in the hands of third parties. Anyone who releases assets without CDTFA consent becomes personally liable for the value transferred.
Loss of Liquor License
Failing to pay sales tax- or alcohol-beverage-tax liabilities can trigger an automatic suspension of your Department of Alcoholic Beverage Control (ABC) liquor license.
Three situations spark suspension:
- Sales tax or penalty debt tied to that license,
- Unpaid alcohol-beverage taxes, or
- A delinquency of three months or more in either category
Even the IRS can seize and sell a state liquor license to satisfy federal tax debts. Paying or entering a CDTFA approved installment agreement lifts the suspension and allows you to petition for reinstatement.
Loss of Contractor License
When ordinary levies, liens, and garnishments do not clear the balance, the CDTFA can ask the Contractors State License Board (CSLB) to deny or suspend a contractor’s license or pending application. The request is issued only after all other collection tools have been exhausted; compliance with an installment plan forestalls the suspension, and payment in full or plan approval obligates CDTFA to request reinstatement.
Revocation of Seller’s Permits and Other Licenses
Under Revenue & Taxation Code § 6070, CDTFA may revoke a seller’s permit—or any CDTFA-issued license—when returns are not filed, taxes remain unpaid, security is not posted, or records are refused. Taxpayers receive written notice and an opportunity to appear for a hearing; if they cure the violation before the hearing, revocation is cancelled. Ignore the notice, and the permit will be revoked sixty days later. Operating after revocation is a misdemeanor, and new permits can be denied while the liability remains.
When a Routine Civil Sales Tax Audit Becomes Criminal
The CDTFA’s Investigations Bureau and local district attorneys prosecute willful non-compliance under the Sales and Use Tax Law and, where the facts warrant, under general theft and money-laundering statutes. Exposure includes:
- Misdemeanor Liability (RTC § 7153) – Any willful violation—failure to file, failure to pay, false statement, record destruction—can bring up to one year in county jail and a fine of $1,000 – $5,000 per count.
- Felony “Zapper” Offenses (RTC § 7153.6) – Possessing, installing, or selling automated sales-suppression devices (phantom-ware)] can draw fines up to $10,000 and restitution of all evaded tax, interest, and penalties.
- Grand-Theft-Style Prosecution – Diverting large sums of sales tax often morphs into felony theft, criminal tax evasion, or money-laundering charges, each carrying multi-year state-prison terms.
- Personal Liability for Owners & Managers (RTC § 6829 / Reg. 1702.5) – Once a business terminates, dissolves, or “goes dark,” the CDTFA may pursue officers, managers, members, or other “responsible persons” for every dollar of unpaid sales tax, interest, and penalties.
Recently, the CDTFA published updated guidance on the protocols and procedures for disputing, or “appealing,” CDTFA determinations. Although the agency provides clear instructions for taxpayers, handling an appeal without professional tax representation is not advisable given the legal and financial complexities involved. It is essential to seek experienced assistance, which is why consulting our experienced dual-licensed CDTFA Audit Attorneys & CPAs at the tax law offices of David W. Klasing is crucial prior to filing an appeal or petition for redetermination. Their specialized knowledge is key in navigating the complex legal framework, preventing potential increases in liabilities and penalties due to improper handling, and ensuring your case is effectively presented to maximize the likelihood of a favorable outcome.
Contact the Tax Law Offices of David W. Klasing If You are Worried About Sales Tax Penalties
At the tax law offices of David W. Klasing, our practice is laser focused on high risk civil and criminal tax controversies. Because we always keep a blend of civil and potentially criminal tax matters in play, the taxing authorities never know which strategy we will deploy. From the moment you engage us, our dual-licensed Criminal Tax Defense Attorneys & CPAs move to audit proof your records, often rebuilding or sanitizing sales tax data before the CDTFA ever sets foot onsite.
We identify the subtle “tells” that signal a looming criminal tax referral and neutralize them before they reach criminal tax investigations. Where penalties have already been proposed, we press for abatement or settlement, leveraging factors such as health crises, natural disasters, or reasonable reliance on professional advice. If the CDTFA tries to pierce the entity veil, we step in to shield owners and managers from personal liability under § 6829 and, when necessary, litigate before the California Office of Tax Appeals (OTA). Because sales-tax fraud often overlaps with federal income-tax evasion, we coordinate defenses on both fronts, ensuring a unified strategy. To date, not one of our Sales or Income Tax audit clients has been criminally prosecuted for tax crimes, even when the engagement began as a high risk eggshell or reverse eggshell audit.
Conversations with accountants lack the sanctuary of the attorney-client privilege. If the CDTFA (or a grand jury) issues a subpoena, your preparer must testify—even about the incriminating statements you thought were private. Only an attorney can cloak consulting CPAs under a Kovel agreement, keeping your disclosures confidential while harnessing the forensic muscle needed to rebut CDTFA assumptions, negotiate penalty abatement, or steer the case away from criminal tax prosecution.
California’s sales tax penalty regime is punitive, cumulative, and when the state believes you acted intentionally, can be life altering. If you have received a CDTFA notice, sense that a “routine” audit is morphing into a criminal tax investigation, or simply want proactive compliance advice, act now. Call the tax law offices of David W. Klasing at (800) 681-1295 or schedule online to secure a reduced-rate initial consultation. Protect your freedom, your livelihood, and your reputation before the CDTFA’s penalties multiply.
