Missouri Pornography Laws (2026): HB 1839 Age Verification

Pornography is legal for adults to privately view and possess in Missouri, and the state's obscenity law targets commercial promotion rather than personal use. What has changed for Missouri in 2026 is age verification: a requirement that has already been enforced for months through an Attorney General rule is about to become a fully codified statute with steep civil penalties.

Is Pornography Legal in Missouri?

Missouri's obscenity statute, Mo. Rev. Stat. Section 573.030 (promoting obscenity in the second degree), criminalizes promoting obscene material, or possessing it with the purpose to promote it, for pecuniary gain, knowing its content and character. It also reaches producing, presenting, directing, or participating in an obscene performance for pecuniary gain, and separately covers material that is "pornographic for minors." A first offense is a class A misdemeanor; a second or subsequent offense is a class E felony.

Because those subsections require a purpose to promote for pecuniary gain, private adult possession or viewing of obscene material without any commercial purpose is not itself a crime. Pecuniary gain is not an element everywhere in the chapter, though. Mo. Rev. Stat. Section 573.020 (promoting obscenity in the first degree) reaches wholesale promotion of obscene material, meaning distribution for resale or redistribution, with no pecuniary-gain element, and it is a class E felony outright. Section 573.030.1(5) likewise omits pecuniary gain where a person promotes, produces, presents, directs, or participates in a performance that is pornographic for minors by computer, electronic transfer, or internet and makes it available to a specific individual the defendant knows to be a minor.

18 U.S.C. Section 2257, the federal record-keeping requirement for producers of sexually explicit content, applies regardless of Missouri law and is not a state-created obligation.

Missouri's Age-Verification Law: A Rule That Predates the Statute

Missouri presents an unusual sequence: the substance of the age-verification requirement has already been enforced for months before the law that codifies it takes legal effect.

An Attorney General administrative rule, issued under the Missouri Merchandising Practices Act, has required covered adult websites to use reasonable age-verification methods since December 1, 2025. In July 2026, the legislature caught up: Governor Mike Kehoe signed HB 1839 (sponsored by Rep. Sherri Gallick, HCS for HBs 1839, 2921 and 3015) on July 9, 2026, amending Chapter 407 of the Missouri Merchandising Practices Act to put the requirement into statute. HB 1839 itself does not take legal effect until August 28, 2026, meaning the underlying AV requirement will have been operating in practice for roughly nine months before its own statutory effective date.

The law applies to any commercial website where at least 33.3% of the content is sexual material harmful to minors. Covered sites must verify a user's age before granting access and are barred from retaining the user's identifying information. Enforcement runs through the Missouri Attorney General in civil court, with penalties of up to $10,000 per day of noncompliance, $10,000 for each instance of improperly retained identification data, and up to an additional $250,000 if a minor is shown to have accessed restricted material.

No lawsuit against either the Attorney General's rule or HB 1839 had been filed as of this writing, despite formal objection letters sent by trade groups, including the Computer & Communications Industry Association, the Missouri Chamber of Commerce, the Free Speech Coalition, and NetChoice. Some platforms responded by exiting the market rather than complying: Pornhub blocked access to Missouri users entirely rather than build age verification for the state.

Child Sexual Abuse Material and Other Offenses Against Minors

Missouri criminalizes possession of child sexual abuse material under Mo. Rev. Stat. Section 573.037, which reaches knowing or reckless possession of material depicting a minor under 18, or obscene material portraying what appears to be a minor. The statute grades severity by the number and type of images. Possessing one still image is a class D felony. It becomes a class B felony if the person possesses more than twenty still images of child sexual abuse material, more than twenty obscene still images, any single motion picture, film, videotape, or other moving image, or has previously been found guilty under the section. A collection of twenty-five still photographs therefore carries the class B grade, not the class D grade that applies to a single image. Punishment applies separately to each item possessed, meaning a defendant found with multiple images or videos can face multiple, stacked counts.

Missouri has a separate legal framework for cases involving minors who create or share images of themselves or other minors. That process is addressed on the Missouri sexting laws page and is not duplicated here.

Nonconsensual Intimate Images (Revenge Porn)

Missouri's nonconsensual-disclosure law, known as Evan's Voice Act, is codified at Mo. Rev. Stat. Section 573.110 alongside Sections 573.112 and 573.114. It criminalizes intentionally disseminating an identifiable person's sexual image, obtained under circumstances where a reasonable person would know the image should remain private, with intent to harass, threaten, or coerce the depicted person, knowing or having reason to know they did not consent. The standard offense is a class D felony; it becomes a class C felony when the depicted person is a minor or a vulnerable person.

The law also creates a private civil cause of action. A successful plaintiff can recover the greater of $10,000 or actual damages, plus attorney's fees, and the statute specifically provides that humiliation or embarrassment alone is an adequate showing of damages, with no physical manifestation required. The law exempts disclosures made for lawful criminal investigations, reporting unlawful conduct, and other legitimate public purposes.

This state remedy is separate from the federal Take It Down Act, which requires platforms to remove nonconsensual intimate imagery, including AI-generated deepfakes, once notified. For platform-level removal steps and a state comparison, see Revenge Porn Laws by State.

Public Indecency

Missouri addresses public sexual conduct through Mo. Rev. Stat. Section 566.093 (sexual misconduct, first degree), effective since January 1, 2017. The statute covers exposing one's genitals under circumstances the person knows are likely to cause affront or alarm, engaging in sexual contact in the presence of a third person likely to be affronted or alarmed, and having sexual intercourse or deviate sexual intercourse in a public place before a third person. A base offense is a class B misdemeanor; it becomes a class A misdemeanor if the person has a prior conviction under the same chapter, or an equivalent out-of-state conviction.

Adult Businesses in Missouri

Missouri regulates sexually oriented businesses directly at the state level, unlike many neighboring states that leave the subject entirely to local ordinances. Mo. Rev. Stat. Section 573.531 bars establishing such a business within 1,000 feet, measured in a straight line, of a primary or secondary school, house of worship, state-licensed day care, public library, public park, residence, or another sexually oriented business. The statute also bars anyone under 18 from the premises, prohibits alcohol on site, requires semi-nude employees to keep at least six feet of distance from patrons and eighteen inches from the floor, bars touching between employees and patrons, and requires the business to close between midnight and 6 a.m.

Two related sections add a narrow local-option structure for adult cabarets, and the narrowness matters: each subsection of Section 573.507 and of Section 573.503 applies only to "any city not within a county and any county," which in Missouri means St. Louis City and county governments. An ordinary municipality such as Kansas City, Springfield, or Columbia cannot act under these two sections at all. Where they do apply, Section 573.507 authorizes, but does not itself impose, a minimum age for admission into an adult cabaret, a requirement that security personnel be present, random drug testing of cabaret employees, and a ban on live public nudity within ten feet of an observer; Section 573.503 allows background checks on cabaret employees for certain prostitution, drug, money-laundering, tax-evasion, and gambling convictions. None of these requirements apply unless the city or county has separately adopted them. Separately, Section 573.540 confirms that the sexually-oriented-business provisions do not preempt local regulation, so any political subdivision may enact ordinances that are the same as or stricter than state law as long as they are not inconsistent with it.

Penalties at a Glance

Practical Risks Beyond the Statute

Criminal exposure under Missouri law is not the only consideration. Employer device and internet-use policies can make viewing adult content on a work computer or network grounds for termination, independent of whether any statute was violated. Federal obligations layer on top of state law: 18 U.S.C. Section 2257 imposes record-keeping duties on producers of sexually explicit content regardless of Missouri's rules, and the federal Take It Down Act creates its own platform takedown obligations for nonconsensual intimate imagery. Anyone facing a specific legal question in this area should consult an attorney for advice specific to their situation.

Frequently Asked Questions

Is pornography legal in Missouri?

Yes, for private adult viewing and possession. Missouri's second-degree obscenity statute, Mo. Rev. Stat. Section 573.030, reaches promoting obscene material, or possessing it with the purpose to promote it, for pecuniary gain, so there is no crime for privately viewing or possessing such material without a commercial purpose. Other offenses in the same chapter do not turn on pecuniary gain at all: Section 573.020 makes wholesale promotion of obscene material a class E felony outright, and Section 573.030.1(5) reaches making a performance pornographic for minors available online to a specific individual the defendant knows is a minor.

Does Missouri require age verification for porn sites?

Yes. An Attorney General rule under the Missouri Merchandising Practices Act has required reasonable age verification on qualifying sites since December 1, 2025. HB 1839, signed July 9, 2026, codifies and expands that requirement into statute effective August 28, 2026.

Has Missouri's age-verification law been challenged in court?

No lawsuit against the Attorney General's rule or against HB 1839 had been filed as of this writing, despite objection letters from trade groups including the Free Speech Coalition and NetChoice. Some sites, including Pornhub, chose to block access to Missouri users rather than comply.

What is the penalty for possessing child sexual abuse material in Missouri?

Under Mo. Rev. Stat. Section 573.037, possessing one still image is a class D felony.
