You can claim as many exemptions as you want, but when its time to file your taxes, you may owe the government money. Too many exemptions will result in too much money coming out of your pay check. You may need this to live check to check during the year, but it will catch up to you. When you file, you will still owe that tax money. You can also claim 0 exemptions. When you file you will have paid too much and have money coming back to you.
