There&#8217;s no separate form for correcting mistakes on Form 940.<\/p>\n<p>Employers have to refile Form 940 for the year the error occurred, check the\u00a0 &#8220;Amended&#8221; box, and enter the full amounts that should have appeared on the original return.<\/p>\n<p>The tax year on the form should always match the year being corrected, not the year the amendment is actually filed.<\/p>\n<h2>Importance of Amending Form 940 For Employers<\/h2>\n<p>An amended return allows an employer to correct FUTA information. Since Form 940 calculations build on one another, even a single wrong figure can ripple through the rest of the form. A correction can affect:<\/p>\n<ul>\n<li>The wage totals from which FUTA taxes are calculated, and payments exempt from FUTA tax<\/li>\n<li>Any adjustments tied to state unemployment tax credits or deposits<\/li>\n<li>The final balance due or overpayment that is shown on the return<\/li>\n<\/ul>\n<p>Catching and fixing these errors early can reduce additional penalties and interest. The IRS applies penalties and charges interest when returns are filed late, and taxes are paid late, so employers should correct underreported FUTA tax and pay any additional amount due as soon as possible.<\/p>\n<h2>What You Can Fix With an Amended Form 940<\/h2>\n<table>\n<tbody>\n<tr>\n<th>Error on Form 940<\/th>\n<th>What Needs To Be Corrected<\/th>\n<\/tr>\n<tr>\n<td>Total payments to employees were reported incorrectly<\/td>\n<td>FUTA wage calculations and total FUTA tax.<\/td>\n<\/tr>\n<tr>\n<td>FUTA wages were calculated incorrectly<\/td>\n<td>FUTA tax before adjustments.<\/td>\n<\/tr>\n<tr>\n<td>A state unemployment tax credit was reported incorrectly<\/td>\n<td>Total FUTA tax after adjustments.<\/td>\n<\/tr>\n<tr>\n<td>State unemployment tax was paid late, and the credit wasn&#8217;t claimed<\/td>\n<td>FUTA tax adjustment.<\/td>\n<\/tr>\n<tr>\n<td>The deposit amount was reported incorrectly<\/td>\n<td>Balance due or overpayment.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Note: An amended Form 940 isn&#8217;t the right form for every change. A business name change is done by writing to the IRS office where the employer filed the return, while an address or responsible party change is filed using Form 8822-B instead.<\/p>\n<h2>The Amended Form 940 Filing Process<\/h2>\n<table>\n<tbody>\n<tr>\n<th>Steps<\/th>\n<th>Required Action<\/th>\n<\/tr>\n<tr>\n<td>Pick the correct form<\/td>\n<td>Use the version of Form 940 for the specific tax year you are correcting.<\/td>\n<\/tr>\n<tr>\n<td>Mark the form as &#8220;Amended&#8221;<\/td>\n<td>Check Box a, &#8220;Amended,&#8221; at the top of page 1.<\/td>\n<\/tr>\n<tr>\n<td>Complete the full return<\/td>\n<td>Enter all the amounts that should have appeared on the original return, not just the difference.<\/td>\n<\/tr>\n<tr>\n<td>Explain the change<\/td>\n<td>Attach a written statement explaining to the IRS why the return is being amended.<\/td>\n<\/tr>\n<tr>\n<td>Check the bottom line<\/td>\n<td>Determine whether the correction results in a balance due or an overpayment.<\/td>\n<\/tr>\n<tr>\n<td>Sign it<\/td>\n<td>Have an authorized person sign the amended Form 940.<\/td>\n<\/tr>\n<tr>\n<td>File the amendment<\/td>\n<td>eFile or mail the paper version to the correct IRS address.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Note: Form 940 amendments use MeF, a different system from IRIS. MeF handles employment tax returns, while IRIS handles information returns such as Forms 1099.<\/p>\n<h2>What to Include in the Amendment Explanation?<\/h2>\n<p>An amended Form 940 needs a clear written explanation of why the return is being corrected. A clear explanation identifies the error, states what&#8217;s being corrected, and explains why, including whether any state unemployment tax adjustment is involved. Electronic filers attach this to the MeF submission; paper filers attach it to the physical return.<\/p>\n<h2>Paper or Electronic Filing for Your Amended FUTA Return<\/h2>\n<p>An amended Form 940 can be filed either electronically or on paper.<\/p>\n<p><strong>Electronic filing:<\/strong> MeF handles amended employment tax returns, including Form 940 amendments. You can submit the required explanation and corrected figures using compatible IRS-approved software or an authorized e-file provider.<\/p>\n<p><strong>Paper filing:<\/strong> An amendment can be mailed to the IRS address listed for returns \u201cWithout a payment,\u201d even if a payment is included. Make sure to confirm the IRS address before mailing, since the IRS mailing addresses can change.<\/p>\n<h2>How an Amended Form 940 Affects FUTA Tax<\/h2>\n<p>Once the numbers are corrected, Form 940 recalculates the employer\u2019s FUTA tax position. Lines 12, 13, 14, and 15a of Form 940 show the new total FUTA tax, deposits, balance due, or overpayment.<\/p>\n<p>If more tax is owed, employers have to pay electronically. If there&#8217;s an overpayment, report it on line 15a, and use line 15b to apply it to next year&#8217;s return or request a refund.<\/p>\n<p>The IRS now issues Form 940 refunds by direct deposit, so routing and account numbers should be ready on lines 15c through 15e.<\/p>\n<h2>Amended Form 940 Rules for Aggregate Filers<\/h2>\n<p>Some filers, such as section 3504 agents and certified professional employer organizations (CPEOs), file a single aggregate Form 940 that combines FUTA information for several employer clients. An amended aggregate return requires Schedule R (Form 940), with corrected allocations that match the aggregate Form 940 totals.<\/p>\n<h2>How 1099Online Supports Amended Form 940 Filing<\/h2>\n<table>\n<tbody>\n<tr>\n<th>Feature<\/th>\n<th>How It Helps<\/th>\n<\/tr>\n<tr>\n<td>Online corrections with guided filing<\/td>\n<td>Prepares corrected Form 940 information using a guided filing workflow.<\/td>\n<\/tr>\n<tr>\n<td>Review before filing<\/td>\n<td>Built-in validations to help you review FUTA wages, adjustments, deposits, balance due, or overpayment before submission.<\/td>\n<\/tr>\n<tr>\n<td>Electronic filing<\/td>\n<td>Skips the paper-filing process and submits the amended Form 940 electronically.<\/td>\n<\/tr>\n<tr>\n<td>Free re-file on rejection<\/td>\n<td>Allows a rejected return to be corrected and refiled at no extra cost.<\/td>\n<\/tr>\n<tr>\n<td>Status tracking<\/td>\n<td>Tracks filing status and IRS acceptance after submission.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Common Mistakes to Avoid When Amending Form 940<\/h2>\n<p><strong>Using last year&#8217;s form-<\/strong> The IRS requires the form for the year being corrected.<\/p>\n<p><strong>Reporting only the difference-<\/strong> The full corrected amounts that should have appeared on the original return are required<\/p>\n<p><strong>Forgetting to check Box a-<\/strong> Without it, the IRS has no way of knowing it&#8217;s an amended return.<\/p>\n<p><strong>Skipping the written explanation-<\/strong> An explanation is required for Form 940 amendments<\/p>\n<p><strong>Mailing to the wrong address-<\/strong> Form 940 paper amendments should use the IRS address listed for returns \u201cWithout a payment\u201d<\/p>\n<p><strong>Leaving off Schedule R-<\/strong> This is required whenever an aggregate return is amended<\/p>\n<h2>FAQs<\/h2>\n<h5>1. Is there a Form 940-X for correcting Form 940?<strong><br \/>\n<\/strong><\/h5>\n<p>There isn&#8217;t a separate Form 940-X. Employers correct Form 940 by using the same form for the year in question and checking the \u201cAmended\u201d box.<\/p>\n<h5>2. Is there a deadline for filing an amended Form 940?<strong><br \/>\n<\/strong><\/h5>\n<p>The IRS doesn&#8217;t have a specific deadline for Form 940 amendments, and errors should be corrected as soon as they are found. However, claims for a FUTA tax credit or refund must be made within 3 years from when the return was filed or 2 years from when the tax was paid, whichever is later.<\/p>\n<h5>3. Do I enter only the difference when amending Form 940?<strong><br \/>\n<\/strong><\/h5>\n<p>No. Employers enter the full amounts that should have appeared on the original return.<\/p>\n<h5>4. Does an amended Form 940 require an explanation?<strong><br \/>\n<\/strong><\/h5>\n<p>Yes. An amended Form 940 requires an explanation of why the return is being corrected.<\/p>\n<h5>5. Where do I mail an amended Form 940?<strong><br \/>\n<\/strong><\/h5>\n<p>A paper amendment should be mailed to the IRS address listed for returns \u201cWithout a payment.\u201d<\/p>\n<h5>6. Can an amended Form 940 result in a refund?<strong><br \/>\n<\/strong><\/h5>\n<p>Yes. If the correction shows an overpayment, the employer can apply it to next year&#8217;s return or request a refund, which the IRS now issues by default via direct deposit.<\/p>\n<div class=\" box-css sub-sec\">\n<p><strong>File Your Amended Form 940 With 1099Online<\/strong><\/p>\n<p>Employers can file amended Form 940 returns through 1099Online and get them to the IRS accurately, without the paper-filing hassle.<\/p>\n<p><a class=\"btn rounded-btn\" href=\"https:\/\/app.1099online.com\/signup\" target=\"_blank\" rel=\"noopener\">eFile Amended Form 940<\/a><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Understanding an Amended Form 940 An amended Form 940 is used by employers to correct a mistake on a Form 940 that has already been filed with the IRS.
