How Old Do You Have to Be to Buy Alcohol in Texas?

You have to be 21 years old to buy alcohol in Texas. There is no lower age and no workaround, not even if a parent, spouse, or guardian is standing at the register with you. Texas Alcoholic Beverage Code Section 106.02 makes it a criminal offense for anyone under 21 to purchase or attempt to purchase any alcoholic beverage, and the penalties climb sharply with each repeat.

The 21 floor comes from the federal National Minimum Drinking Age Act of 1984, which conditions a portion of highway funding on states adopting that minimum.¹ Every state complies, Texas included.²

What Happens If a Minor Tries to Buy Alcohol

Section 106.071 of the Alcoholic Beverage Code sets a single schedule of punishments for all minor alcohol offenses: purchase, attempt to purchase, possession, consumption, and using a fake ID all count toward the same tally. Prior deferred dispositions count as convictions for enhancement purposes, so a quiet case from last year still raises the stakes on the next one.

First Offense

A first violation is a Class C misdemeanor with a maximum fine of $500. The court must also order 8 to 12 hours of community service tied to alcohol education or prevention, suspend the minor’s driver’s license for 30 days (or deny issuance if they don’t yet have one), and require completion of an alcohol awareness program.³⁴

Second Offense

Still a Class C misdemeanor, but the community service grows to 20 to 40 hours and the license suspension doubles to 60 days. The alcohol awareness program can be ordered again at the court’s discretion.³

Third or Subsequent Offense

At the third offense, the picture changes. For minors who are not children under the Family Code, the fine range jumps to $250 to $2,000, jail time of up to 180 days becomes available, and the license suspension stretches to 180 days. The minor also loses eligibility for deferred disposition, which is the mechanism that normally keeps a conviction off the record.³ Two prior citations, including things that felt minor at the time, strip that option away on the third.

What About Buying With a Parent There?

Texas does carve out a family exception, but only for possession and consumption, never for purchase. A person under 21 may legally possess alcohol while in the visible presence of an adult parent, guardian, spouse, or an adult to whom a court has granted custody.⁵ Consumption has a slightly narrower list and works as an affirmative defense if the minor drank in the visible presence of an adult parent, guardian, or spouse.⁶

“Visible presence” is literal. The supervising adult has to be able to see the minor the whole time the minor has or is drinking the alcohol. Another room doesn’t count. And the exception does not stretch to buying: the qualifying adult must be the person who actually makes the purchase. A 20-year-old handing cash to the cashier is still committing a crime whether or not a parent is next to them.

Fake IDs and False Age Claims

Presenting a fake or altered ID, or just verbally claiming to be 21 or older in order to buy alcohol, is a separate offense under Section 106.07. It carries the same escalating structure: Class C misdemeanor for a first or second offense, with the harsher third-tier penalties kicking in on a subsequent violation.³ Because fake ID offenses and underage purchase offenses count under the same punishment statute, a minor caught once with a fake ID and once buying alcohol already carries two strikes toward the enhanced third-offense penalties.

Adults Who Buy for Minors

The adult on the other side of the transaction faces far steeper consequences than the minor. Under Section 106.06, buying alcohol for or giving alcohol to someone under 21 is a Class A misdemeanor, punishable by up to a year in jail and a fine of up to $4,000. If the minor then causes serious bodily injury or death to someone because of that alcohol, the charge becomes a state jail felony.⁷

The exceptions match the possession and consumption rules: a parent, guardian, spouse, or court-appointed custodian may provide alcohol to their minor as long as that adult is visibly present throughout. Civil exposure can follow too. An adult who knowingly serves alcohol to someone else’s minor child can be sued for damages under Section 2.02 of the Alcoholic Beverage Code.⁷

Calling 911 Does Not Trigger a Citation

Two safe harbors override the normal underage rules, and they matter.

A minor who calls 911 or requests emergency medical help for a possible alcohol overdose, their own or someone else’s, is protected from prosecution for underage drinking. The minor has to be the first person to request help and, if the emergency involves someone else, has to stay on the scene and cooperate with medical and law enforcement personnel.⁶

A parallel protection applies to sexual assault. A minor who reports a sexual assault, or is the victim of a reported assault, cannot be prosecuted for alcohol possession or consumption that was happening at the time, whether the report goes to a health care provider, law enforcement, or a Title IX coordinator.⁵

Driving With Any Alcohol at All Under 21

The 0.08 percent BAC limit that applies to adult drivers does not apply to drivers under 21 in Texas. Any detectable amount of alcohol in a minor’s system while operating a motor vehicle or watercraft is a separate criminal offense: Driving Under the Influence of Alcohol by a Minor.⁸

License suspensions for a confirmed detectable amount of alcohol:

First offense: 60 days
Second offense: 120 days
Third or subsequent offense: 180 days

Refusing a breath or blood test carries its own penalties: a 180-day suspension for a first refusal and a two-year suspension for any subsequent refusal.⁸

If a minor’s BAC actually hits 0.08 percent or higher, they can be charged as an adult with DWI. A first adult DWI is a Class B misdemeanor with a fine up to $2,000 and 72 hours to 180 days in jail. A second becomes a Class A misdemeanor, and a third is a third-degree felony with a potential prison sentence of two to ten years.⁸
