How can I determine if I owe taxes from my W2 form?

To determine if you owe taxes based on your W-2 form, compare the total amount of taxes withheld from your wages to the amount of tax you owe based on your income. If the withheld amount is less than what you owe, you may need to pay additional taxes. If the withheld amount is more, you may be eligible for a tax refund.
