How Can You Correct Schedule H?: Household Employer Taxes (2026 IRS Guide)

This guide covers “How Can You Correct Schedule H?” within household employer taxes. The following material presents the IRS treatment of this topic, including the qualifications, exceptions, and examples in the source section. Read the rules alongside the facts of your own situation before deciding what to report, deduct, or document.

Adapted from Publication 926 (2026), Household Employer’s Tax Guide, published by the Internal Revenue Service. This guide retains the source edition’s years, amounts, deadlines, and examples. It is guidance for that edition, not a statement that the same figures apply to every tax year.

How Can You Correct Schedule H?

If you discover that you made an error on a Schedule H (Form 1040), the forms used to correct the error depend on whether the Schedule H was attached to another form or whether it was filed by itself.

Schedule H attached to another form.

If you discover an error on a Schedule H that you previously filed with Form 1040, 1040-SR, or 1040-NR, file Form 1040-X, Amended U.S. Individual Income Tax Return, and attach a corrected Schedule H. If you discover an error on a Schedule H that you previously filed with Form 1040-SS, file a new Form 1040-SS and attach a corrected Schedule H. If you discover an error on a Schedule H that you previously filed with Form 1041, file an “Amended” Form 1041 and attach a corrected Schedule H.

Schedule H filed by itself.

If you discover an error on a Schedule H that you filed as a stand-alone return, file another stand-alone Schedule H with the corrected information. In the top margin of your corrected Schedule H, write (in bold letters) “CORRECTED” followed by the date you discovered the error. In addition, explain the reason for your correction and the date the error was discovered in a statement attached to the corrected Schedule H. If you have an overpayment, also write “ADJUSTED” or “REFUND” in the top margin, depending on whether you want to adjust your overpayment or claim a refund. (See Overpayment of tax, later.)

When to file.

File a corrected Schedule H when you discover an error on a previously filed Schedule H. If you’re correcting an underpayment, file a corrected Schedule H no later than the due date of your next tax return (generally, April 15 of the following calendar year) after you discover the error. If you’re correcting an overpayment, file a corrected Schedule H within the refund period of limitations (generally, 3 years from the date your original form was filed or within 2 years from the date you paid the tax, whichever is later).

Underpayment of tax.

You must pay any underpayment of social security and Medicare taxes by the time you file the corrected Schedule H. Generally, by filing on time and paying by the time you file the return, you won’t be charged interest (and won’t be subject to failure-to-pay or estimated tax penalties) on the balance due. However, underreported FUTA taxes will be subject to interest.

Overpayment of tax.

You may either adjust or claim a refund of an overpayment of social security and Medicare taxes on a previously filed Schedule H. However, if you’re correcting an overpayment and are filing the corrected Schedule H within 90 days of the expiration of the period of limitations, you can only claim a refund of the overpayment.

Adjust the overpayment.

If the corrected Schedule H is filed with a Form 1040-X or an amended Form 1041, adjust your return by indicating on line 23 of the Form 1040-X or on line 30a of the Form 1041 that you would like the overpayment applied to your estimated taxes on Form 1040, 1040-SR, 1040-SS, 1040-NR, or 1041 for the year in which you’re filing the corrected Schedule H. If the corrected Schedule H is filed as a stand-alone return, adjust your return by writing “ADJUSTED” in the top margin (in bold letters). If you adjust your return, you won’t receive interest on your overpayment. If the corrected Schedule H will be filed within 90 days of the expiration of the refund period of limitations, you may not adjust the return and must claim a refund for the overpayment. You may not adjust your return to correct overpayments of FUTA tax.

Claim for refund process.

If the corrected Schedule H is filed with a Form 1040-X or an amended Form 1041, claim a refund by indicating that you would like the overpayment refunded to you on Form 1040-X, line 22, or Form 1041, line 30b. If the corrected Schedule H is filed as a stand-alone return, claim a refund by writing “REFUND” in the top margin (in bold letters). You will receive interest on any overpayment refunded, unless the overpayment is for FUTA tax because you were entitled to increased credits for state contributions.

Required repayment or consent.

If you previously overreported social security and Medicare taxes, you may adjust your overpayment only after you’ve repaid or reimbursed your employees the amount of the overcollection of employee tax. You reimburse your employees by applying the overwithheld amount against taxes to be withheld on future wages. You may claim a refund for the overpayment only after you’ve repaid or reimbursed your employees the amount of the overcollection or you’ve obtained consents from your employees to file the claim for refund for the employee tax. Include a statement that you repaid or reimbursed your employees, or obtained their written consents in the case of a claim for refund, in Part II of Form 1040-X or in a statement attached to the amended Form 1041 or the stand-alone corrected Schedule H.

Filing required for Forms W-2 or Forms W-2c.

Whether you previously underreported tax or overreported tax, you will generally be required to file Form W-2, or their territorial equivalents (if none was previously filed), or Form W-2c to reflect the changes reported on your corrected Schedule H.

Additional Medicare Tax.

Generally, you may not correct an error in Additional Medicare Tax withholding for wages paid to employees in a prior year unless it is an administrative error. An administrative error occurs if the amount you entered on Schedule H isn’t the amount you actually withheld. For example, if the Additional Medicare Tax actually withheld was incorrectly reported on Schedule H due to a mathematical or transposition error, this would be an administrative error. If a prior year error was a nonadministrative error, you may correct only the wages subject to Additional Medicare Tax withholding.

Any underwithheld Additional Medicare Tax must be recovered from employees on or before the last day of the calendar year in which the underwithholding occurred. Any excess Additional Medicare Tax withholding must be repaid or reimbursed to employees before the end of the calendar year in which it was withheld.

Additional information.

For more information about correcting errors on a previously filed Schedule H, see Form 944-X: Which process should you use? on page 6 of Form 944-X, and the Instructions for Form 944-X (substitute “Schedule H” for “Form 944-X”).
