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.
How Much Should My Arizona Estimated Payments Total?If you have to make estimated payments, your payments, when added to your Arizona withholding, must total either 90% of the tax due for 2013, or 100% of the tax due for 2012.
You can use your 2012 tax to figure the amount of payments that you must make during 2013 only if you were required to file and did file a 2012 Arizona income tax return.
When Should I Make My Arizona Estimated Payments?The State of Arizona says to make your payments in four equal installments. The due dates for these installments for a 2013 calendar year taxpayer are as follows:
Installment Due Date
First: April 15, 2013
Second: June 17, 2013 (because June 15th falls on a Saturday, you have until June 17, 2013 to make this payment)
Third: September 16, 2013 (Because September 15th falls on a Sunday, you have until September 16, 2013 to make this payment)
Fourth: January 15, 2014
Where Do I Find the Arizona Form to Make an Estimated Tax Payment?You can find tax forms, and the instructions, at the Arizona Department of Revenue website.
