One responsible party can receive only one EIN per day. This nationwide limit applies across all entity types and all EIN application methods. Filing for a second entity, switching from the online tool to fax or mail, or having a third-party designee submit an application does not create a stated exception to the limit.
The key is identifying the responsible party correctly. In general, that is the person who ultimately owns or controls the entity or exercises ultimate effective control over it. Because the daily limit follows that person—not merely the business name—an owner or controller organizing multiple entities should plan the EIN requests accordingly.
How the one-EIN-per-day limit works
The limit applies whether an EIN is requested online, by telephone, by fax, or by mail. Telephone EIN applications are available only to international applicants, but the same daily restriction applies to that method. Using two methods on the same day does not increase the number of EINs that one responsible party may receive.
The restriction concerns receiving EINs, not simply the number of forms someone prepares. If several new entities identify the same person as their responsible party, that person can receive only one EIN per day. The applicants should sequence the requests rather than attempting to submit them simultaneously through different channels.
This rule applies to all entity types. It therefore matters when one person controls several corporations or LLCs, participates in multiple new ventures, or is associated with several trusts or estates. The entity names and structures may differ, but the applicable person or special classification determines how the daily limit is counted.
Who counts as the responsible party?
For Form SS-4 applicants, the responsible party generally is the person who ultimately owns or controls the entity or who exercises ultimate effective control over it. Special classifications in the Form SS-4 instructions apply to trusts, estates, government entities, public companies, partnerships, and tax-exempt organizations.
Except for a government entity, the responsible party must be an individual rather than another entity. Applicants should therefore avoid listing a parent company, management company, LLC, or corporation in place of the controlling individual merely because that organization is involved in ownership or administration.
Partnerships can require particular care because several people may share ownership or management. The selected person should fit the responsible-party standard rather than simply being the person available to complete the application. For more context, see EIN for a Partnership: Responsible Party Rules Explained.
The same analysis applies regardless of the state in which an entity is organized. A state filing contact, registered agent, organizer, or form preparer is not automatically the responsible party for the federal EIN application. The controlling-person question is discussed further in Washington EIN Application: What Counts as a Responsible Party?.
Special rules for trusts and estates
Trusts and estates do not always fit the ordinary business-owner model. For a trust, the daily limit is applied to the grantor, owner, or trustor. This means that multiple trust EIN requests connected to the same applicable individual cannot be treated as unrelated merely because the trusts have different names or trustees.
For a decedent estate, the daily limit is applied to the decedent. For a bankruptcy estate, it is applied to the debtor. Executors, administrators, trustees, and other representatives should use the classification that applies to the estate rather than assuming the daily limit follows the person preparing the request.
Common scenarios and how to plan
| Scenario | How the limit applies | Practical approach |
|---|---|---|
| One person controls two new entities | The same responsible party can receive only one EIN per day, even though the entities are different. | Choose which entity’s request to complete first and handle the other on a later day. |
| Two entities have different responsible parties | The limit is measured per responsible party, but each application must identify its actual responsible party. | Confirm control separately for each entity; do not select a different person solely to avoid the limit. |
| An online request has already been made | Changing to fax, mail, or an eligible telephone application does not avoid the all-method limit. | Do not submit another same-day request for a different entity under the same responsible party. |
| Several trusts share the same grantor, owner, or trustor | The limit is applied to that grantor, owner, or trustor. | Sequence the trust EIN requests across separate days. |
| A representative prepares applications | Using a preparer or designee does not change who ultimately owns, controls, or effectively controls the entity. | Track requests by the actual responsible party, not by the person transmitting the form. |
| A decedent or bankruptcy estate needs an EIN | The limit is applied to the decedent for a decedent estate and to the debtor for a bankruptcy estate. | Organize the filing schedule using the applicable estate classification. |
A foreign owner may also need to work through responsible-party identification and application-method questions. The daily limit remains applicable across the available methods. Applicants dealing with foreign-owner identification can review Can a Foreign Owner Get an EIN Without an SSN? for additional context.
A practical process for multiple EIN requests
- List each entity separately. Record its exact legal identity and entity type so that applications are not confused with one another.
- Identify the responsible party for each entity. Focus on the individual who ultimately owns or controls the entity or exercises ultimate effective control. Apply the special classification where a trust, estate, government entity, public company, partnership, or tax-exempt organization is involved.
- Group the requests by responsible party. If the same individual appears on several applications, those requests cannot all produce EINs on the same day.
- Place the requests in order. Decide which entity needs to be handled first, then schedule the remaining requests for later days without trying to rotate application methods.
- Use one application method for each entity. The IRS instructs applicants to use only one method for a particular entity so that it does not receive more than one EIN. Do not send a fax or mail application as a backup after submitting the same entity’s request another way.
- Keep an application log. Note the entity, responsible party, method used, and whether an EIN was received. This administrative record can help prevent an accidental duplicate request or a same-day conflict.
EINs are issued by the Internal Revenue Service. For eligible online applicants, the IRS online EIN tool provides approved EINs directly and does not charge a fee. That tool is limited to applicants whose principal place of business is in the United States or a U.S. territory. The availability of the online tool does not alter the one-EIN-per-responsible-party-per-day limit.
Problems that can disrupt an EIN plan
Treating each entity as a separate daily allowance
The allowance does not reset merely because the next application involves a different LLC, corporation, partnership, trust, or other entity. If the same responsible party is associated with the requests, only one EIN may be received by that responsible party that day.
Listing a nominee or preparer as the responsible party
The person completing or transmitting an application is not necessarily the person who ultimately owns or controls the entity. Assigning the role based on convenience can produce an inaccurate responsible-party entry. Determine the controlling individual before scheduling requests.
Submitting the same entity through multiple methods
A second submission is not a way to accelerate the first. The IRS directs applicants to choose only one application method for each entity to prevent that entity from receiving more than one EIN. Maintain a clear record of pending and completed submissions before anyone sends another application.
Applying ordinary business assumptions to trusts or estates
For daily-limit purposes, a trust request is associated with the grantor, owner, or trustor. A decedent estate is associated with the decedent, while a bankruptcy estate is associated with the debtor. Tracking only the trustee, executor, or representative may therefore lead to an incorrect filing schedule.
Decision checklist before requesting another EIN
- Have you identified the individual who ultimately owns, controls, or exercises ultimate effective control over each entity?
- Does a special classification for a trust, estate, government entity, public company, partnership, or tax-exempt organization affect the responsible-party entry?
- Has that responsible party already received an EIN today for any entity?
- If a trust is involved, have you checked the requests associated with the same grantor, owner, or trustor?
- If an estate is involved, are you applying the rule to the decedent or debtor, as appropriate?
- Has anyone already submitted an application for this particular entity by another method?
- Are you avoiding a duplicate application rather than treating another method as a backup?
- If using the IRS online tool, is the entity’s principal place of business in the United States or a U.S. territory?
If the same applicable responsible party has already received an EIN that day, the straightforward approach is to place the next entity later in the filing sequence. Correctly identifying the responsible party, separating entity records, and using one method per entity will make a multi-entity EIN plan easier to manage.
Frequently Asked Questions
Can one responsible party get two EINs in the same day for two different LLCs?
No. A responsible party can receive only one EIN per day across all entity types, so using two different LLCs does not create a separate daily allowance.
Can I use online filing for one EIN and fax for another on the same day?
Not to bypass the daily limit. The one-EIN-per-day restriction applies whether an EIN is requested online, by telephone, by fax, or by mail. Telephone applications are available only to international applicants.
Does hiring a third-party designee allow another EIN to be issued that day?
No stated exception allows a responsible party to receive another EIN that day merely because a third-party designee prepares or submits the request. The responsible party is generally the individual who ultimately owns, controls, or exercises ultimate effective control over the entity.
Whose daily EIN limit applies when several trusts share one grantor?
For a trust, the daily limit is applied to the grantor, owner, or trustor. If several trust requests are associated with the same applicable person, that person can receive only one EIN per day.
Whose limit applies to an estate EIN application?
For a decedent estate, the daily limit is applied to the decedent. For a bankruptcy estate, the limit is applied to the debtor.
