What Happens if a Business Doesn’t Collect Sales Tax?

Sales tax compliance is a fundamental obligation for businesses selling taxable goods and services in states where they have nexus. You might wonder: what are the consequences when a business fails to register, collect, or remit sales tax correctly? These consequences can range from financial penalties and interest to audits, enforcement actions, and—in extreme cases—criminal charges. Understanding these outcomes helps businesses proactively manage compliance and mitigate risk.

This article walks you through what can happen if a business doesn’t collect sales tax and how to mitigate potential consequences.

Key Takeaways

• Sales tax is a trust tax. Businesses collect it on behalf of the state—not as revenue. Failure to remit is treated as a serious offense.
• Businesses are liable even if tax was not collected from customers. States can require payment out of pocket, plus penalties and interest.
• Penalties can stack quickly. Late filing, late payment, and audit-related penalties can significantly increase the total amount owed.
• Interest accrues from the original due date, compounding liabilities over time.
• Sales tax audit penalties are common when businesses fail to register, underreport taxable sales, or ignore filing requirements.
• Owners and officers may be personally liable, even if the business is an LLC or corporation.
• Proactive compliance—registering, collecting accurately, and filing on time—helps prevent audits, penalties, and enforcement actions, protecting operations and cash flow.

Why Sales Tax Matters

Revenue from sales tax is a major source of funding for public services such as education, transportation, law enforcement, and healthcare. According to the Tax Foundation, sales tax is the second-largest revenue source for U.S. states.

Businesses with nexus in a state are required to collect and remit sales tax from their customers, but that money should not be treated as revenue. Rather, it is a trust fund held on behalf of the state. States treat remittance obligations seriously and have broad powers to recoup unpaid taxes and enforce compliance.

Who is Liable for Not Collecting, Filing, and Remitting Sales Tax

Sales tax liability extends beyond the business itself. Because sales tax is a trust fund, failure to register, collect, or remit can create personal exposure for individuals responsible for the business’s finances and tax compliance.

Business Entity Liability

At a minimum, the business is directly responsible for collecting and remitting sales tax in every state where it has nexus. States can assess unpaid tax, interest, and penalties against the business even if tax was not collected from customers. For example, New York considers vendors trustees of sales tax funds, liable for taxes owed regardless of collection.

Responsible Persons

Many states hold certain individuals personally liable. This includes:

• Officers, directors, or managers with control over finances
• Individuals who authorize tax payments or sign returns
• Partners or LLC members in certain business structures

California defines responsible persons as anyone with control or supervision over sales tax filing or payment who fails to ensure taxes are remitted.

In partnerships, LLCs, and sole proprietorships, partners or owners may be personally liable by default. Some states extend this liability to all members of a pass-through entity, meaning personal assets could be used to satisfy unpaid sales tax obligations.

Consequences for Not Registering, Collecting, or Remitting Sales Tax

If a business neglects their sales tax responsibilities, the penalties can be vast. These are some common consequences businesses may face for not collecting or remitting sales tax.

Penalties on Late Filings, Late Payments, and Non-Filing

States impose structured penalties when returns are filed late or not at all:

• Late Filing Penalty: States assess a percentage of the unpaid tax for each month a return is filed late. For example, New York’s penalty for late filing starts at 10% of the tax due in the first month plus 1% per additional month, up to a maximum of 30%.
• Late Payment Penalty: Similar penalties apply when tax is not paid by the due date. For example, Georgia charges 5% of the tax due or $5 (whichever is greater) for late payments. Each additional month of nonpayment accrues the same interest.
• Missed Return Penalty: In states like Kentucky, businesses pay 2% of the total unpaid tax for each 30 days a return or payment is late, with additional collection fees that can reach 25%.

When a state sets both a penalty rate and a flat fee, it will typically collect the higher amount. For example, a $5 flat penalty on a $1,000 sales tax return might seem minimal, but if the alternative is 5% of $1,000, the penalty jumps significantly. Moreover, these penalties often stack, meaning late filing, late payments, and negligence can quickly compound the total amount owed.

Interest Accruals

Like penalties, interest accrues from the original due date until payment, increasing the total debt beyond the unpaid tax. Interest rates vary by state and may be adjusted quarterly or annually.

Some states, such as Utah and Arizona, base interest on the federal short-term rate plus an additional 2–3%. Other states set independent rates or offer discounted rates. For example, Colorado has both a regular and discounted rate, with the discounted rate applied when taxpayers pay prior to a notice of deficiency or within 30 days of such notice—typically 3% lower than the regular rate.

Interest is calculated on tax owed and, in many jurisdictions, continues to apply until the liability is fully satisfied.

Sales Tax Audit Penalties

Failing to collect or remit sales tax increases audit risk. States may initiate audits centered on past sales, invoices, and records to determine if:

• Taxes were incorrectly collected
• Returns were underreported
• Nexus existed without registration

During audits, jurisdictions can assess additional audit-related penalties, including negligence or fraud penalties on top of normal late-filing penalties.

Enforcement Actions: Liens, Levies, and Garnishments

When a business repeatedly fails to register, collect, file, or remit sales tax—even after receiving notices—state departments of revenue have powerful enforcement tools to satisfy outstanding tax liabilities. Beyond penalties and interest, these actions can directly impact business finances, assets, credit, and reputation.

Tax Liens

A tax lien is a legal claim that a state can file against a business’s real or personal property to secure payment of unpaid sales tax, interest, and penalties. Once recorded, a lien:

• Can prevent the sale or refinancing of property until the debt is resolved.
• May appear in public records, affecting creditworthiness and business reputation.
• Often remains in effect for years until the obligation is satisfied.

For example, California’s Board of Equalization and Franchise Tax Board may impose a state tax lien against your property for unpaid sales tax, and that lien extends to all real and personal property you own, including future acquisitions.

Levies and Garnishments

A levy permits a state to seize property or funds to satisfy sales tax debts. Examples include:

• Bank account levies, where the state directs financial institutions to turn over funds from your accounts.
• Seizure of business or personal property, which may then be sold at public auction to satisfy the tax debt.

States such as Michigan provide that once a tax debt becomes delinquent, the Department may levy assets—including bank accounts—to collect the amount owed.

In addition to levies, many states use garnishment to collect delinquent sales tax liabilities. This usually requires a legal process or judgment, after which the state directs an employer or financial institution to withhold wages or intercept funds owed to the taxpayer. The Missouri DOR notes that once a judgment exists, it can lead to wage or bank garnishments to collect unpaid tax debt.

Severe Cases (Criminal and Civil Penalties)

Sales tax noncompliance typically doesn’t lead to criminal consequences. However, if a business intentionally collects sales tax and refuses to remit it, states may escalate to criminal charges such as tax evasion, fraud, or theft of public funds. These can carry:

• Substantial fines
• Restitution
• Possible incarceration

Many states define willful non-remittance as a serious offense. For example, if a business willfully fails to collect or remit sales tax as required by law in New York, civil or criminal penalties may apply, even including jail time.

Mitigating Risk: Compliance and Remediation

Businesses can minimize exposure to penalties and enforcement by:

• Registering early and accurately in all states with nexus.
• Filing and paying on time to reduce penalties and maintain vendor discounts.
• Using Voluntary Disclosure Agreements (VDAs) to resolve past noncompliance, often reducing penalties and limiting audit exposure.
• Maintaining accurate records to support filings and audit defense.
• Consulting a sales tax professional to navigate state-specific rules and optimize compliance.
