Taxes, withholding, smoking rules, and age limits that can affect your trip
All gambling winnings are taxable in Maryland for residents and nonresidents.
For larger wins, Maryland requires state income-tax withholding—lottery and certain pari-mutuel proceeds over $5,000 trigger automatic withholding at 9.5% for residents (8.75% for nonresidents), in addition to federal rules; you still must report smaller wins on your return even if nothing was withheld.
Separately, Maryland casinos are non-smoking indoors, though properties may designate outdoor or separate areas for smoking.
Finally, you must be 21+ to play in Maryland casinos (and 18+ for pari-mutuel racing). Knowing these rules ahead of time helps you avoid surprises at the cage—or on your tax return.
Timeline of casinos in Maryland
Maryland casino gaming has an interesting history that is quite unique. Back in 1943, slot machines were deregulated, and this led to a thriving nightlife and gambling scene in and around Annapolis. At the time, the area was known as “Little Vegas” to people in the know.
In the 1960s, the good times came to an end for people who enjoyed the activity when regulations were reinstated and enforced. Predictably, tourism dropped off precipitously, and the nightclubs fell by the wayside.
A prolonged period of dormancy ensued, but there was a seismic shift in 2008 when a new law was passed that allowed for legal slot machines at licensed venues. Hollywood Casino Perryville became the first gaming venue to open under the new regulatory parameters in 2010.
Slots were the only game in town at first, but in 2012, the legislature approved the addition of table games and other forms of casino gaming. Now, Marylanders have the freedom to play all casino games whenever they choose to do so.
