The Internal Revenue Service is being urged to modernize the process of filing amended tax returns to allow for corrections to original tax return filings and expand e-filing to include amended tax returns, according to a new report publicly released today by the Treasury Inspector General for Tax Administration (TIGTA).

At present, taxpayers file Form 1040X, Amended U.S. Individual Income Tax Return, to correct previously filed income tax returns. Claims filed on an amended tax return can relate to any item of income, loss, exclusion, deduction, or credit and may result in a tax refund. The IRS received more than four million amended tax returns in Fiscal Year (FY) 2012. TIGTA recommended that the Commissioner, Wage and Investment Division, revise Form 1040 to enable taxpayers to amend their original tax return using this form, expand e-filing to include amended tax returns, and conduct a review of the 44 amended tax returns TIGTA identified for which potentially erroneous refunds were issued to determine the proper tax liability.

The IRS agreed with two of TIGTA’s recommendations and disagreed with one recommendation. Although the IRS disagreed with revising Form 1040, the IRS plans to consider changing the format and appearance of Form 1040X. The IRS also plans to consider e-filing of amended tax returns based on available funding and resources.
