IRS Form 1040X (2018): Amended Tax Return

What IRS Form 1040X (2018) Is For

IRS Form 1040X (2018) allows taxpayers to amend a previously filed individual income tax return. You may need to file Form 1040X if you discover errors or omissions on your original tax return. Common reasons include:

  • Reporting additional income, such as wages, interest, or capital gains

  • Correcting deductions, credits, or exemptions that were missed or entered incorrectly

  • Changing your filing status or dependents

  • Responding to an IRS notice about a discrepancy or correction

Each tax year requires a separate Form 1040X. If you owe additional tax, you should pay it immediately to limit penalties and interest.

When You’d Use Form 1040X for 2018 (Late or Amended Filing)

Form 1040X for 2018 is filed when adjustments are needed on your original return. You can file this amendment after the IRS has processed your original return. The general time limit to file is three years from the original filing deadline or two years from the date you paid the tax, whichever is later.

For most taxpayers, the due date for refund claims for the 2018 tax year was April 15, 2022. After this date, the IRS limits refund eligibility unless you qualify for exceptions such as military or disability-related provisions. If you owe additional tax, you can still correct your return even after the refund period expires.

Key Rules Specific to 2018

The 2018 tax year introduced significant changes under the Tax Cuts and Jobs Act. Taxpayers should note the following updates when preparing an amended return:

  • The redesigned Form 1040 replaced Forms 1040A and 1040EZ.

  • Standard deductions increased, while many itemized deductions were limited in scope.

  • The Child Tax Credit was expanded, affecting taxable income calculations.

  • Business owners using Schedule C saw changes in allowable expense deductions.

  • Certain combat-injured veterans were given extended claim deadlines under the Combat-Injured Veterans Tax Fairness Act.

Amended returns for 2018 cannot be filed online. You must print and mail Form 1040X to the IRS address listed in the instructions.

Step-by-Step (High Level)

  1. Gather documents: Collect your original tax return, W-2s, 1099s, IRS notices, and other supporting documents.

  2. Complete Form 1040X: Enter original, changed, and corrected amounts across three columns (A, Column B, and C). Provide clear explanations for each change in Part III.

  3. Attach schedules: Include all revised or new schedules, such as Schedule C for business income or deductions, or capital gains forms.

  4. File by mail: 2018 amended returns cannot be electronically filed. Mail the completed form to the appropriate IRS address.

  5. Keep copies: Retain a copy of your amended return, proof of mailing, and payment records for your account.

Common Mistakes and How to Avoid Them

  • Filing before the original return is processed: File Form 1040X only after receiving confirmation that the IRS has processed your original return.

  • Some attachments are missing: Include all necessary forms, schedules, and supporting documentation.

  • Incomplete explanations: Clearly describe every amendment in Part III to help the IRS process your case efficiently.

  • Miscalculations: Check math carefully, especially in Column B, which reflects the net change.

  • Statute deadline errors: Remember the three-year limit for refund claims or the two-year limit from the date tax was paid.

  • Incorrect address: Mail the form to the address specified in the IRS instructions for amended returns.

What Happens After You File

Once submitted, an amended tax return typically takes 8 to 12 weeks to process. More complex amendments may require up to 16 weeks to process. You can check your amended return status using the “Where’s My Amended Return?” tool on the IRS website.

The tool shows three stages: Received, Adjusted, and Completed. If you owe additional tax, penalties, and interest accrue from the original due date. Payments can be made by check, money order, or through online payment options. Direct deposit is not available for 2018 amended returns.

FAQs

How long do I have to file an amended return for the 2018 tax year?

You generally have three years from the original filing deadline or two years from when you paid the tax, whichever is later. For most 2018 returns filed on time, the deadline was April 15, 2022. After that date, refunds are limited unless an exception applies.

Will I owe penalties and interest on an amended return?

If your amended return results in additional tax, you may owe penalties and interest from the original due date. Paying the balance promptly or setting up an installment agreement can reduce additional charges.

Can I get a transcript of my 2018 tax account?

Yes, you can order a transcript at IRS.gov, call 800-908-9946, or submit Form 4506-T. The transcript includes income, withholding, and adjustments to your 2018 return. Reviewing it before filing helps avoid duplicate or incorrect entries.

Do I also need to amend my state tax return?

In most cases, yes. If your federal return changes, you may also need to amend your state tax return. Some states automatically update their records in response to federal changes, while others require a separate filing to update their records. Check your state’s tax agency for details.

What if the IRS made an error on my original return?

If the IRS corrected a simple mathematical or clerical mistake, you do not need to file Form 1040X. The IRS will send a notice explaining the change. If you disagree, respond directly to the notice instead of filing an amendment.

Frequently Asked Questions

IRS Form 1040X (2018): Amended Tax Return

What IRS Form 1040X (2018) Is For

IRS Form 1040X (2018) allows taxpayers to amend a previously filed individual income tax return. You may need to file Form 1040X if you discover errors or omissions on your original tax return. Common reasons include:

  • Reporting additional income, such as wages, interest, or capital gains

  • Correcting deductions, credits, or exemptions that were missed or entered incorrectly

  • Changing your filing status or dependents

  • Responding to an IRS notice about a discrepancy or correction

Each tax year requires a separate Form 1040X. If you owe additional tax, you should pay it immediately to limit penalties and interest.

When You’d Use Form 1040X for 2018 (Late or Amended Filing)

Form 1040X for 2018 is filed when adjustments are needed on your original return. You can file this amendment after the IRS has processed your original return. The general time limit to file is three years from the original filing deadline or two years from the date you paid the tax, whichever is later.

For most taxpayers, the due date for refund claims for the 2018 tax year was April 15, 2022. After this date, the IRS limits refund eligibility unless you qualify for exceptions such as military or disability-related provisions. If you owe additional tax, you can still correct your return even after the refund period expires.

Key Rules Specific to 2018

The 2018 tax year introduced significant changes under the Tax Cuts and Jobs Act. Taxpayers should note the following updates when preparing an amended return:

  • The redesigned Form 1040 replaced Forms 1040A and 1040EZ.

  • Standard deductions increased, while many itemized deductions were limited in scope.

  • The Child Tax Credit was expanded, affecting taxable income calculations.

  • Business owners using Schedule C saw changes in allowable expense deductions.

  • Certain combat-injured veterans were given extended claim deadlines under the Combat-Injured Veterans Tax Fairness Act.

Amended returns for 2018 cannot be filed online. You must print and mail Form 1040X to the IRS address listed in the instructions.

Step-by-Step (High Level)

  1. Gather documents: Collect your original tax return, W-2s, 1099s, IRS notices, and other supporting documents.

  2. Complete Form 1040X: Enter original, changed, and corrected amounts across three columns (A, Column B, and C). Provide clear explanations for each change in Part III.

  3. Attach schedules: Include all revised or new schedules, such as Schedule C for business income or deductions, or capital gains forms.

  4. File by mail: 2018 amended returns cannot be electronically filed. Mail the completed form to the appropriate IRS address.

  5. Keep copies: Retain a copy of your amended return, proof of mailing, and payment records for your account.

Common Mistakes and How to Avoid Them

  • Filing before the original return is processed: File Form 1040X only after receiving confirmation that the IRS has processed your original return.

  • Some attachments are missing: Include all necessary forms, schedules, and supporting documentation.

  • Incomplete explanations: Clearly describe every amendment in Part III to help the IRS process your case efficiently.

  • Miscalculations: Check math carefully, especially in Column B, which reflects the net change.

  • Statute deadline errors: Remember the three-year limit for refund claims or the two-year limit from the date tax was paid.

  • Incorrect address: Mail the form to the address specified in the IRS instructions for amended returns.

What Happens After You File

Once submitted, an amended tax return typically takes 8 to 12 weeks to process. More complex amendments may require up to 16 weeks to process. You can check your amended return status using the “Where’s My Amended Return?” tool on the IRS website.

The tool shows three stages: Received, Adjusted, and Completed. If you owe additional tax, penalties, and interest accrue from the original due date. Payments can be made by check, money order, or through online payment options. Direct deposit is not available for 2018 amended returns.
