Preheat oven to 400°F and line a large sheet pan with parchment paper.
In a skillet over medium heat, cook ground beef until browned, then drain excess fat and stir in taco seasoning with 1/4 cup water.
Spread half of the tortilla chips in an even layer on the prepared sheet pan.
Top with half of the seasoned meat, half of the cheese, half of the black beans, and half of the corn.
Add a second layer of chips and repeat with remaining meat, cheese, beans, and corn.
Scatter tomatoes, olives, and jalapeños over the top.
Bake for 12-15 minutes until cheese is melted and bubbly, then serve immediately with sour cream, salsa, and guacamole.
