If you have turned 18, you must be thrilled to enter a new and exciting phase of your life. To enjoy this phase, you have to be a responsible adult and use your newfound freedom in the right way. Here are some points you need to remember as a new adult.

  1. The first thing to keep in mind is that you are now legally responsible for every action of yours. If you violate a law, you will be liable to be tried as an adult and even land in jail.
  1. You will now have to pay taxes based on your income, state of residence, and other factors. You will also have to file tax returns every year dutifully.
  1. If you are a boy, you have to register with the National Selective Service within a month of turning 18. Failing to do so can incur you a fine of $250,000 or five years in prison (1).

Frequently Asked Questions

1. Why is turning 18 so essential?

The 18th birthday is an important milestone as it opens doors to many new responsibilities, privileges, and opportunities. The decisions you make after gaining this freedom play an essential role in determining the course of your life.

2. Why did 18 become the age of adulthood?

The age of 21 as an entry to adulthood was changed to 18 during the Vietnam war. Because 18 was considered a suitable age for men to be drafted into wars, many demanded 18 to be the right age for granting voting rights. Moreover, after the age of 21 was initially set, there were plenty of advancements in public education; therefore, most countries decided on 18 as the age of adulthood.

Turning 18 is certainly a moment to commemorate since you are now officially old enough to engage in many activities. From opening a bank account and buying a car to running for state office, the things you can do at 18 seem endless. However, this newfound freedom comes with many responsibilities. For example, you are now completely responsible for any legal document you sign and owe income taxes to the state. Therefore, finding the right balance between freedom and restraint is key to ensuring your first step into adulthood.
