A Quick Primer on Amended Returns
May 3, 2013
Now that the April 15th filing deadline has passed the last thing anyone probably wants to think about is their taxes. But what do you do when you realize after filing your taxes that you qualified for a credit you did not take? Or you receive a W-2 or 1099 you forgot to include on your return? If you made a mistake on your 2012 tax return you can fix any errors by filing an Amended Return. An Amended Return is filed using Form 1040X, which can be found here. Note that an Amended Return cannot be filed electronically. Amended Returns do not have to be filed because of mathematical errors you made on your return; the IRS will correct those for you. Also, you do not need to file an amended return if you forgot to attach a tax form to your return. So if you forgot to attach a W-2 to your tax return there is no need to file an amended return, but if you did not include the income from a W-2 on your return you will need to file an amended return. Make sure to include any schedules or forms changed by your Amended Return when you mail your 1040X. File a separate 1040X for each year’s return that you are amending. One last note: amending your federal return can affect your state tax liability. Missouri does not have a special form for filing an amended return. Taxpayers should use Form MO-1040 Individual Income Tax Long Form and indicate they are filing an Amended Return. Taxpayers should also include a copy of their Federal Amended Return and Form MO-A.
