If you forgot a deduction or missed a credit that would have increased your refund we can file an amended tax return to get you that money that’s rightfully yours. We can also correct your filing status, the number of dependents you claim, increase or decrease your gross income that you reported on your original tax return.
If your original return reports the correct information but includes math errors, there is no need to file an amendment. The IRS regularly checks returns to ensure mathematical accuracy. In the event it finds a math error, your return is automatically recalculated. The IRS will notify you in writing of any recalculation and its effect on your tax bill or refund.
Limitations to Amend
You have a limited amount of time to file an amended tax return; otherwise, the IRS will not accept it. This must be done within three years from the date you filed your original return or within two years from the date you paid the tax, whichever is later. For example, if you file your 2012 tax return on March 15, 2013, then you have until April 15, 2016 to get your amended tax return to the IRS.
As a result, you have no obligation to file an amended tax return after the relevant limitation period even if the correction would increase the amount of tax you owe. However, the IRS will not issue a refund check for an amended return you file after the limitation period.
