You don't necessarily have to cut carbohydrates, but eating excessive carbs is not advisable.
So if you are a 180lb guy who works out a few days per week and has a sedentary job, somewhere around 200 grams will help fuel your bodily functions and your workouts without any excess being wasted and converted to fat.
Most bodybuilders consume around 50% of total calories from carbs whereas low carb advocates can consume as low as 10-15%.
Technically, carbs are not an essential nutrient so we don't need to eat them to survive.
As a general guideline, somewhere around 40-50% carbs, 25-30% protein, and 20-30% fat is a solid benchmark during a cutting program.
