If you are self-employed, or for some reason you don't have enough taxes withheld from your income (salary, investments, etc.) to cover the amount of taxes you'll owe to the State of Arizona for the year, you need to pay estimated taxes. If you don't, and you wait until you file your tax return next year to pay your taxes, you could be subject to penalties imposed by the State of Arizona. Don't forget that you might also have to pay estimated taxes to the IRS for your federal tax liability.
