Misleading advertising laws in the United States operate on three tracks. The Federal Trade Commission enforces the FTC Act against deceptive commercial claims and can impose civil penalties that, after inflation adjustments, exceed $53,000 per violation. Competitors harmed by a rival’s false ads can sue under the federal Lanham Act. And nearly every state has its own consumer protection statute that lets individual consumers file suit, often with double or triple damages and recovery of attorney fees. Which law applies, and who can use it, depends on who was harmed and how.
How the FTC Defines a Deceptive Ad
The FTC applies a two-part test. An ad is deceptive if it contains a statement, or omits information, likely to mislead a consumer acting reasonably under the circumstances, and the misleading element is material — meaning it would influence a decision to buy or use the product.1Federal Trade Commission. Advertising FAQs – A Guide for Small Business The Commission looks at the ad as a whole rather than parsing individual words. If the combined impression of images, text, and fine print would steer a reasonable person toward a purchase they otherwise wouldn’t make, the ad is deceptive.
Businesses also carry a substantiation burden. Before running any ad that makes an objective factual claim, the company must already possess evidence supporting it.2Federal Trade Commission. FTC Policy Statement Regarding Advertising Substantiation When an ad references a specific level of proof, such as “studies show” or “doctors recommend,” the company must hold at least that level of evidence. Health and safety claims face a higher bar, requiring competent and reliable scientific evidence from qualified professionals using accepted methods.3Federal Trade Commission. Advertising Substantiation Principles
The Two Federal Statutes
The FTC Act
The FTC Act is the primary federal tool against deceptive advertising. Under 15 U.S.C. § 45, unfair or deceptive acts or practices in or affecting commerce are unlawful, and the FTC is empowered to prevent them.4Office of the Law Revision Counsel. 15 USC 45 – Unfair Methods of Competition Unlawful; Prevention by Commission The Commission can investigate companies, issue cease-and-desist orders, pursue civil penalties, and prescribe rules defining specific deceptive practices.5Federal Trade Commission. Federal Trade Commission Act This authority covers advertising across every medium, from television to social media to product packaging. Individual consumers do not sue under the FTC Act; enforcement is the government’s job.
The Lanham Act
The Lanham Act, at 15 U.S.C. § 1125, creates a private right of action, but only for businesses. A company that misrepresents the nature, characteristics, qualities, or geographic origin of its own or another company’s products in commercial advertising can be sued by a competitor likely to be damaged.6Office of the Law Revision Counsel. 15 USC 1125 – False Designations of Origin, False Descriptions, and Dilution Forbidden Courts have consistently required an injury to a commercial interest in reputation or sales. A consumer who was misled has no claim under this statute and needs to look to state law.
Available relief under the Lanham Act includes injunctions to stop the false advertising, the competitor’s lost profits, disgorgement of the defendant’s profits in cases involving intentional deception, and attorney fees in exceptional circumstances.
State Consumer Protection Statutes
Every state has an unfair and deceptive acts and practices statute, often called a “Little FTC Act.” These laws are where individual consumers actually get remedies. Nearly all states allow consumers to file private suits under their UDAP statute, and about half authorize double or triple damages when the consumer wins. Most states also require the losing business to pay the consumer’s attorney fees, which removes a major barrier to bringing a smaller-dollar case.
State attorneys general have independent enforcement authority alongside consumer suits. They can investigate businesses, issue subpoenas, and file their own actions. State-level investigations often reach deceptive practices that fly under the federal radar because the business is small or operates in a single region. Available remedies include injunctions, restitution to harmed consumers, and voiding of contracts obtained through deception.
What These Laws Reach
Pricing Tricks and Hidden Fees
Inflated “original” prices are a longstanding target. When a retailer lists a product at $200, marks it to $99, and calls it a sale, but never actually sold the item at $200 for any meaningful period, the FTC treats that fictitious former price as deceptive. Bait-and-switch — advertising a low-priced item to draw customers in, then steering them to a pricier alternative — is separately prohibited.
A company doesn’t need to lie outright to run afoul of the rules. Omitting material information can be equally misleading. An ad promoting a “$29 monthly payment” while burying a 24.99% interest rate and mandatory service fees in the fine print creates a false impression of total cost. Drip pricing, where mandatory charges appear one at a time during checkout, is a variation the FTC has flagged: unavoidable fees should appear in the upfront advertised price, and failing to include them can violate the FTC Act.7Federal Trade Commission. Bringing Dark Patterns to Light
Dark Patterns and Subscription Traps
The FTC defines dark patterns as “design practices that trick or manipulate users into making choices they would not otherwise have made and that may cause harm.”7Federal Trade Commission. Bringing Dark Patterns to Light These include cancellation mazes for recurring charges, items sneaked into carts, manipulative free-trial enrollments, and pre-checked boxes authorizing data sharing or add-on purchases. The Commission treats them as violations of Section 5 when they meet the deceptive-or-unfair standard.
The FTC’s negative option rule, which took effect in January 2025, directly targets subscription traps. Sellers must provide a cancellation method at least as simple as the sign-up method.8Federal Register. Negative Option Rule Online sign-up means online cancellation. The rule bars penalties for canceling and prohibits pitching additional products during cancellation unless the consumer agrees to hear the offer. Sellers must disclose all material terms before collecting billing information and obtain express informed consent before charging.
Influencer and Endorsement Disclosures
The FTC’s Endorsement Guides, revised in 2023 and found at 16 CFR Part 255, apply advertising law to social media influencers and online reviews. When an endorser has a material connection to the brand — payment, free products, a family or business relationship, or even the possibility of being paid — that connection must be disclosed clearly and conspicuously.9eCFR. 16 CFR Part 255 – Guides Concerning Use of Endorsements and Testimonials in Advertising In interactive media the disclosure should be “unavoidable.” A buried hashtag or a vague “thanks to Brand X” at the end of a long caption doesn’t meet the standard, and a video endorsement needs a spoken disclosure, not just text in the description. Both the influencer and the brand can face enforcement.10Federal Trade Commission. Endorsements, Influencers, and Reviews
Environmental Claims
The FTC’s Green Guides at 16 CFR Part 260 set rules for terms like “recyclable,” “compostable,” “biodegradable,” and carbon offset claims.11Federal Trade Commission. Green Guides Each term carries specific evidentiary and disclosure requirements — for example, an unqualified “biodegradable” claim requires scientific evidence that the product will completely decompose within one year after customary disposal.12Federal Trade Commission. Part 260 – Guides for the Use of Environmental Marketing Claims The Guides were last updated in 2012 and the FTC has been reviewing them, seeking public comment as recently as 2023. Terms not specifically addressed, like “plastic-free” or “climate positive,” still fall under the general principle that any environmental claim must be truthful, substantiated, and not misleading.
Comparative Advertising
The FTC encourages truthful comparisons that name competitors and compare products on measurable attributes or price.13Federal Trade Commission. Statement of Policy Regarding Comparative Advertising Disparaging a competitor’s product is permitted so long as the statements are truthful and non-deceptive. Trouble comes when the comparison cherry-picks data, uses outdated test results, or fails to clearly identify the basis of the comparison. A 2019 speed test used to claim superiority in 2026 would likely be deceptive.
Penalties
The base statutory penalty under the FTC Act is $10,000 per violation.4Office of the Law Revision Counsel. 15 USC 45 – Unfair Methods of Competition Unlawful; Prevention by Commission That figure is adjusted annually for inflation and stands at $53,088 per violation as of 2025.14Federal Trade Commission. FTC Publishes Inflation-Adjusted Civil Penalty Amounts for 2025 Each separate violation counts as its own offense, and each day a company continues to violate an order counts as a new violation. A nationwide campaign running for weeks can generate penalties in the millions.
The FTC also uses its Penalty Offense Authority under Section 5(m)(1)(B). Through this program, the Commission sends companies formal notices listing conduct that prior FTC administrative decisions have found deceptive. Companies that receive a notice and then engage in the listed conduct face civil penalties of up to $50,120 per violation.15Federal Trade Commission. Notices of Penalty Offenses When stopping an ad isn’t enough to undo the damage, the FTC can order corrective advertising, requiring the company to spend its own advertising dollars correcting the false impression it created.16Federal Trade Commission. Federal Trade Commission Advertising Enforcement
One important limit: in 2021 the Supreme Court held in AMG Capital Management v. FTC that Section 13(b) of the FTC Act does not authorize the Commission to seek monetary relief like restitution or disgorgement, only injunctive relief.17Supreme Court of the United States. AMG Capital Management LLC v. FTC The FTC can still pursue money through other statutory provisions, but the ruling closed what had been the agency’s most-used route to recovering money for defrauded consumers. That gap is part of why state UDAP suits and private actions matter more than they did a decade ago.
What a Misled Consumer Can Do
Three paths are available, and they can be pursued in parallel.
- File a complaint with the FTC at ReportFraud.ftc.gov. The Commission won’t resolve an individual case, but complaints go into the Consumer Sentinel database shared with more than 2,000 law enforcement partners, and enough complaints about the same company can trigger an investigation.18Federal Trade Commission. ReportFraud.ftc.gov
- Contact the state attorney general. State AG offices investigate deceptive advertising and can seek restitution on behalf of affected consumers, and they are often the most effective route against businesses operating in one state or region.
- File a private lawsuit under the state UDAP statute. Depending on the state, actual damages may be doubled or tripled, and attorney fees are typically recoverable, which makes it feasible to bring modest-dollar cases.
What generally is not available to a consumer is a federal Lanham Act suit. That statute is reserved for competitors who suffer commercial injury from a rival’s false claims.6Office of the Law Revision Counsel. 15 USC 1125 – False Designations of Origin, False Descriptions, and Dilution Forbidden A business watching a competitor make false claims can seek an injunction, lost profits, and disgorgement in cases of willful deception. For everyone else, state consumer protection law is the way in.
