Form 843 for Nonprofits: How to Request a Tax Refund or Penalty Abatement
Estimated reading time: 12 minute(s)
Most nonprofits know Form 990 by heart, but very few have heard of Form 843. That changes the moment your organization is hit with a penalty, interest charge, or fee that never should have been assessed. Form 843 is the form the IRS built for that situation, and knowing when it applies can save your organization real money. Form 843, Claim for Refund and Request for Abatement, is the form nonprofits use to ask the IRS to refund or remove certain taxes, penalties, interest, or fees assessed in error. It applies to items that don’t have a dedicated correction form of their own. Instead of writing a letter and hoping someone reads it, Form 843 gives the IRS a structured claim: what was assessed, why it was wrong, and what relief you’re asking for. For most nonprofits, it comes up after something has already gone sideways. Maybe you paid a penalty you later learned wasn’t owed, or an employee had too much Social Security tax withheld across two jobs. The organization can file Form 843 itself, usually through an officer with signing authority. An authorized representative acting under a valid Form 2848 power of attorney, a paid preparer, or the organization’s accountant can also file on its behalf. This is where organizations get tripped up. Form 843 can’t be used for income, estate, or gift tax refunds or abatements. It doesn’t cover FICA, RRTA, or income tax withholding refunds claimed by an employer, and it can’t amend a return you already filed.Employment tax corrections use Form 941-X, 943-X, 944-X, or 945-X, depending on the original return. Filing Form 843 for the wrong kind of claim only slows things down.What Is Form 843?
