Federal 1040 tax return amendment and repoting on 1040X (Amended Tax Return)

Tax payers may need to amend their previously filed tax returns if they find that they had errors on it.

Some of the common errors include:

  • Missing a 1099/Corrected 1099 reporting
  • Missing a W2/Corrected W2 reporting
  • Change of filing status from Single to Married fiing jointly.
  • Foreign tax credit carry back

Amending Tax Returns [1040X]

Use form 1040X, Amended U.S. Individual Income Tax Return, to correct errors or omissions that was submitted on a return. The correction may result in the tax payer receiving an additional refund or owing additional taxes.

For instance, if a tax payer discovered that he had failed to include in her income the $10,000 additional income he had won on a America Got Talent show, he should file Form 1040X for the same tax year to add the $10,000 value to his income.

A return may also be amended if a more advantageous way of preparing the return is available. For example: a tax payer might have originally filed Form 1040 using the standard deduction. When he found that he had not reported all of his income, he also discovered that itemizing deductions would reduce his tax liability. He may claim his itemized deductions on Form 1040X. He would additionally complete Schedule A and attached it to the amended return.

Tax payers must include with their amended 1040X return any form, schedule, or statement that changed or might have been required had the original return been filed using the current method.

Due Date for Amending Returns Using Filing Form 1040X

Generally, tax payers must file an amended return within three years of the date the original return was filed, or within two years of the date the original tax was paid, whichever is later. If a return is filed on or before the filing deadline, the IRS considers April 15 to be the filing date.

If the IRS granted the tax payer an extension, tax payers must file the amended return by the date they the return was filed during the extension period.  Alternatively, tax payers should use the April 15 date if they filed the return after the extension period expired.

Example: Thomas wants to amend his 2018 income tax return. The original return was due April 15, 2019.  Thomas filed his return April 2, 2019. Thomas must file his amended return no later than April 15, 2022.
