Form Overview

IRS Form 3491 - 3491

IRS Form 3491 is the Employee Retention Credit (ERC) Allocation form. It is used by employers who have multiple related entities and need to divide the credit among them for a tax year.

The form records the total ERC amount, the allocation percentages or dollar amounts for each entity, and the identifying information for each entity.

Quick Facts

Employers with two or more related entities that claim the ERC for the same calendar year.
The form records the total ERC amount, the allocation percentages or dollar amounts for each entity, and the identifying information for each entity.
File the allocation with the original ERC‑claiming return (usually the employer’s Form 941‑X or the original 941) for the year the credit was earned.
Attach Form 3491 to the appropriate employment‑tax return and mail to the IRS address listed in the form’s instructions for that return.
Incorrect allocations cause mismatched credit amounts, trigger IRS notices, and can delay refunds or lead to penalties.

Complete the identification section for each entity and enter the allocated dollar amount. 4. Attach the completed Form 3491 to the original filing and retain a copy for your records.

Common confusion points

Allocation vs. separate claims

→ Confirm only one total credit is allocated

Percentage rounding

Small rounding differences can cause totals to miss 100%

→ Adjust one entity’s amount to balance

Signature authority

Unclear who can sign

→ Use an officer listed on the entity’s Form 1120 or 1065

Mailing address

Different addresses for Form 941 vs. 941‑X

→ Follow the address in the specific return’s instructions

Amended credit amount

Changing the total ERC after filing

→ File a new Form 941‑X and attach an updated Form 3491
