Applying for an Employer Identification Number (EIN) is usually much simpler than opening a bank account, forming an LLC, or applying for a business license.
In fact, most businesses applying online do not upload a folder of legal documents to the IRS. What you primarily need is accurate information about the business, its legal structure, and the individual who controls it.
An EIN is a nine-digit federal tax identification number assigned by the IRS. It commonly looks like:
12-3456789
Businesses use an EIN for federal tax reporting, hiring employees, opening business bank accounts, applying for licenses, setting up payroll, and completing many financial or compliance processes.
As of 2026, the current IRS Form SS-4 is the December 2025 revision. IRS
Quick Answer: What Do You Need to Apply for an EIN?
For most U.S. businesses, have the following information ready before starting:
| EIN Application Requirement | What You Need |
|---|---|
| Legal business name | Exact name from formation documents |
| Trade name / DBA | If different from legal name |
| Entity type | LLC, corporation, partnership, sole proprietorship, etc. |
| Business mailing address | Address where IRS correspondence should be sent |
| Physical business address | If different from mailing address |
| State and county | Principal business location |
| Responsible party name | Person who ultimately owns or controls the entity |
| Responsible party SSN or ITIN | Usually required for the online application |
| LLC member count | If applying for an LLC |
| State of formation | For an LLC or other entity |
| Business start date | Month and year |
| Accounting year-end | Usually December for many businesses |
| Reason for applying | New business, employees, banking, entity change, etc. |
| Expected employees | Agricultural, household, and other employees |
| First wage payment date | If employees are involved |
| Principal business activity | What the business actually does |
| Products/services | Clear description |
| Previous EIN | If the entity has ever had one |
| Form SS-4 | Required when applying by mail or fax and useful for preparation |
For an online EIN application, the IRS generally verifies this information directly rather than asking you to upload articles of organization, operating agreements, passports, or other business documents. IRS
The Most Important Point: EIN Application “Documents” Are Mostly Information
Many people search for documents required for an EIN application expecting a checklist similar to a loan or immigration application.
That is not how the standard IRS EIN process works.
For a typical domestic business applying online, you generally do not upload:
- Articles of Organization
- Operating Agreement
- Certificate of Incorporation
- Driver’s license
- Passport
- Business bank statements
- Utility bills
- Business license
- Tax returns
You should still keep your formation documents beside you because the EIN application must match your legally registered business information.
The IRS specifically recommends forming a legal entity such as an LLC, corporation, or partnership with the state before applying for an EIN.
Documents You Should Have Beside You Before Applying
Even when the IRS does not require you to upload them, several documents can prevent mistakes.
| Document | Why It Helps |
|---|---|
| Articles of Organization | Confirms LLC legal name and formation date |
| Articles of Incorporation | Confirms corporation information |
| Certificate of Formation | Confirms state registration details |
| Partnership Agreement | Helps verify partnership structure and ownership |
| Operating Agreement | Helps identify LLC ownership and responsible party |
| DBA / Fictitious Name Registration | Confirms trade name |
| SSN or ITIN record | Helps enter responsible-party TIN correctly |
| Prior EIN notice | Important if the entity previously received an EIN |
| Trust agreement | Useful for trust EIN applications |
| Estate documents | Useful when applying for an estate |
Think of these as reference documents, not necessarily documents that must be submitted with every EIN application.
Legal Business Name: Get This Exactly Right
The legal business name on the EIN application should match the name under which your entity was legally formed.
For example, if your state formation document says:
Northstar Digital Solutions LLC
do not casually enter:
Northstar Digital
unless that is simply being listed separately as the trade name.
The IRS specifically instructs businesses to enter their names based on their registration or formation records.
Legal Name vs. DBA
These are not necessarily the same.
| Type | Example |
|---|---|
| Legal entity name | Blue Harbor Technologies LLC |
| Trade name / DBA | Blue Harbor |
| EIN belongs to | Blue Harbor Technologies LLC |
Your DBA does not replace the legal business name on the EIN application.
Responsible Party Information
One of the most important EIN requirements is identifying the responsible party.
The responsible party is generally the individual who ultimately owns, controls, or effectively controls the business and its funds or assets.
For example:
| Entity | Typical Responsible Party |
|---|---|
| Corporation | Principal officer |
| Partnership | General partner |
| LLC | Individual owner/member with ultimate control |
| Sole proprietorship | Owner |
| Trust | Grantor, owner, or trustor |
| Estate | Executor or administrator |
| Tax-exempt organization | Principal officer |
Except for certain government entities, the responsible party generally must be a real individual, not another company.
A registered agent, incorporation service, accountant, attorney, or nominee should not automatically be entered simply because that person helped form the company.
Do You Need an SSN to Get an EIN?
For the IRS online EIN application, the responsible party generally needs a:
Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN).
The IRS online system is currently intended for domestic organizations whose principal place of business is in the United States or U.S. territories and whose responsible party has an SSN or ITIN.
However, this does not mean every foreign owner must obtain an SSN before the business can ever receive an EIN.
Foreign applicants who cannot use the online system may use Form SS-4 and alternative IRS application methods.
EIN Application Without an SSN or ITIN
This issue is especially important for foreign founders.
The current Form SS-4 instructions state that when a responsible party does not have and is ineligible to obtain an SSN or ITIN, the applicant can enter “foreign” or “N/A” in the applicable responsible-party taxpayer identification field.
This option applies in the Form SS-4 process; it does not make the applicant eligible for the domestic online EIN application.
Example
A German entrepreneur owns a Wyoming LLC but:
- Lives in Germany
- Has no SSN
- Has no ITIN
- Is not eligible for an SSN
The EIN process may still be possible through the international/Form SS-4 procedure even though the owner cannot use the standard domestic online application.
Documents Required for EIN Application for an LLC
An LLC should generally be legally formed with its state before applying for an EIN.
Prepare:
| Information | Example |
|---|---|
| Legal LLC name | Summit Commerce LLC |
| Formation state | Delaware |
| Formation date | September 15, 2026 |
| Business address | U.S. principal location |
| Mailing address | If different |
| Number of members | 1, 2, 3, etc. |
| Responsible party | Controlling individual |
| SSN/ITIN | If using online application |
| Tax classification information | As applicable |
| Business activity | Online retail |
| Start date | September 2026 |
The IRS specifically warns that applying before the entity is legally formed can delay the EIN process.
Does a Single-Member LLC Need an EIN?
Not always for federal income tax purposes.
A domestic single-member LLC that:
- Has no employees,
- Is not subject to applicable excise taxes, and
- Has not elected corporate taxation
may generally use the owner’s taxpayer identification number for federal income-tax purposes because it is treated as a disregarded entity.
However, the IRS can still assign the LLC its own EIN if the owner wants one.
In practice, a separate EIN can also be useful when dealing with:
- Banks
- Payroll providers
- Vendors
- Business licenses
- Payment processors
- Business credit
- Privacy separation
A single-member LLC does need its own EIN in certain circumstances, including when it has employees or elects to be treated as a corporation or S corporation.
Documents Required for EIN Application for a Multi-Member LLC
A multi-member domestic LLC generally needs an EIN because the default federal classification is typically a partnership unless the LLC elects another eligible tax classification.
Have ready:
| Requirement | Information to Prepare |
|---|---|
| Legal LLC name | As registered with state |
| Formation state | State jurisdiction |
| Formation date | State-approved date |
| Member count | Total LLC members |
| Responsible party | Controlling individual |
| Responsible-party SSN/ITIN | When applicable |
| Principal address | Business location |
| Business activity | Specific description |
| Accounting year | Fiscal year-end |
You do not ordinarily enter every member’s SSN into the basic EIN application. The IRS wants the appropriate responsible party.
Documents Required for EIN Application for a Corporation
A corporation generally needs an EIN.
Before applying, have your:
| Corporate Information | What to Prepare |
|---|---|
| Articles of Incorporation | For reference |
| Legal corporate name | Exact state-registered name |
| Incorporation state | Delaware, Texas, California, etc. |
| Incorporation date | Official formation date |
| Principal officer | Usually responsible party |
| Officer’s SSN/ITIN | For online application |
| Business address | Principal place of business |
| Expected employees | If applicable |
| Accounting year-end | Corporate tax year |
| Principal activity | Nature of business |
The EIN application itself does not replace your state incorporation process.
The proper sequence is generally:
Form corporation → obtain EIN → establish federal/business accounts and tax compliance.
EIN Application for an S Corporation
An EIN does not automatically make a corporation or LLC an S corporation.
An EIN identifies the business for federal tax purposes.
S corporation treatment requires a separate tax election when the entity qualifies.
For an LLC planning to elect S corporation status, the practical sequence commonly starts with:
Form LLC → obtain EIN → make the applicable S corporation election.
Do not select information on the EIN application merely because you plan to make a future tax election without understanding how the business is currently classified.
Documents Required for EIN Application for a Partnership
A partnership generally needs its own EIN.
Prepare:
- Partnership’s legal name
- Trade name, if applicable
- Business address
- Partnership start date
- General partner/responsible party
- Responsible party’s SSN or ITIN where required
- Principal business activity
- Accounting year-end
- Expected number of employees
- Previous EIN information, if applicable
A sole proprietor who later creates a partnership generally needs a new EIN because the legal/tax structure has changed.
Documents Required for EIN Application for a Sole Proprietor
A sole proprietor may not need an EIN in every situation.
An EIN is commonly required when the sole proprietor:
- Hires employees
- Has certain retirement plans
- Is subject to certain federal tax requirements
- Changes into another legal structure
A sole proprietor may also request an EIN for legitimate business or banking purposes even when federal law does not otherwise require one.
The information is relatively simple:
| Requirement | Details |
|---|---|
| Owner’s legal name | Individual’s legal name |
| Trade name | DBA if applicable |
| SSN/ITIN | Owner identification |
| Business address | Principal location |
| Business start date | Month/year |
| Principal activity | Type of business |
| Employees | Expected number if applicable |
Generally, one sole proprietor does not need a separate EIN for every DBA operated under the same sole proprietorship.
Documents Required for EIN Application for a Nonprofit
An organization generally should be legally formed before applying for its EIN.
Have ready:
| Nonprofit Information | Why It Matters |
|---|---|
| Legal organization name | EIN identity |
| Formation document | Confirms organization exists |
| State of formation | Required entity information |
| Formation date | EIN application |
| Principal officer | Responsible party |
| Officer SSN/ITIN | Typically needed for online application |
| Mailing address | IRS correspondence |
| Organization activity | Describes purpose |
| Fiscal year-end | Tax reporting |
An EIN does not grant federal tax-exempt status.
It is simply the organization’s federal taxpayer identification number.
A nonprofit seeking recognition under Section 501(c)(3) or another exempt classification generally completes the separate applicable exemption process after organization and EIN formation.
The IRS specifically advises tax-exempt organizations not to request an EIN until they are legally formed.
Documents Required for an Estate EIN
An estate may require an EIN when it becomes a separate tax-reporting entity after a person’s death.
Useful information includes:
| Information | Typical Requirement |
|---|---|
| Decedent’s legal name | Yes |
| Decedent’s SSN | Usually relevant |
| Date of death | Important |
| Estate legal name | Yes |
| Executor/administrator name | Responsible party |
| Executor information | Required |
| Mailing address | Estate correspondence |
| Accounting year | Needed for tax reporting |
An estate EIN is different from the deceased person’s Social Security number.
Documents Required for a Trust EIN
Whether a trust needs a separate EIN depends on the type of trust and tax treatment.
If an EIN is required, have available:
- Trust name
- Trust agreement
- Trust creation/funding date
- Grantor or responsible-party information
- Trustee contact information
- Mailing address
- Trust type
- Accounting information
- Existing taxpayer identification information
The responsible party for a trust is generally the grantor, owner, or trustor rather than someone who merely performs administrative services.
EIN Requirements for Foreign-Owned U.S. LLCs
Foreign-owned U.S. LLCs are one of the most searched EIN situations because their owners often do not have U.S. Social Security numbers.
Start with one important distinction:
The LLC’s location and the owner’s location are not necessarily the same.
A foreign national can own a U.S.-formed LLC.
For example:
Owner: India resident
Entity: Wyoming LLC
Owner SSN: None
Owner ITIN: None
The company may still need and obtain an EIN.
However, the standard domestic online EIN tool generally requires an eligible responsible party with an SSN or ITIN.
When the responsible party has no SSN or ITIN and is ineligible for one, Form SS-4 instructions allow the appropriate foreign/N/A entry, and an alternative application method may be necessary.
International Applicant EIN Checklist
For a foreign or international applicant, prepare:
| Information | What You Need |
|---|---|
| Form SS-4 | Completed accurately |
| U.S. entity legal name | Exact formation name |
| U.S. formation documents | Keep available for reference |
| State of formation | Required |
| Formation date | Required |
| Foreign owner name | Responsible party |
| SSN/ITIN | If owner has one |
| “Foreign” or N/A | Potentially appropriate if ineligible for SSN/ITIN |
| Foreign address | Enter accurately |
| U.S. mailing address | If applicable |
| Business activity | Clearly described |
| Application reason | New business, banking, tax requirement, etc. |
If the applicant’s principal place of business is outside the United States, the IRS currently allows international applicants to use designated telephone, fax, or mail EIN procedures rather than the domestic online application.
Form SS-4: What Information Does the IRS Actually Ask For?
Understanding Form SS-4 makes EIN preparation much easier.
The current form asks for information including:
| Form SS-4 Area | Information |
|---|---|
| Line 1 | Legal entity name |
| Line 2 | Trade name |
| Line 3 | Executor, administrator, trustee, or care-of name |
| Lines 4a–4b | Mailing address |
| Lines 5a–5b | Physical street address |
| Line 6 | County and state |
| Lines 7a–7b | Responsible party and taxpayer ID |
| Line 8 | LLC information |
| Line 9 | Entity type |
| Line 10 | Reason for applying |
| Line 11 | Business start/acquisition date |
| Line 12 | Closing month of accounting year |
| Line 13 | Expected employees |
| Line 14 | Certain employment-tax filing information |
| Line 15 | First date wages were paid |
| Line 16 | Principal business activity |
| Line 17 | Specific products/services |
| Line 18 | Previous EIN question |
The December 2025 Form SS-4 remains the current form shown by the IRS in 2026.
How to Describe Your Business Activity
Do not make the business description unnecessarily vague.
Too vague
Consulting
Better
Business management consulting for small retail companies
Too vague
E-commerce
Better
Online retail sale of consumer home and kitchen products
Too vague
Technology
Better
Software development and cloud-based subscription services
Your description should make it clear what the business actually sells or does.
Choosing the Correct Reason for Applying
Form SS-4 asks why you are requesting an EIN.
Common reasons include:
| Reason | Example |
|---|---|
| Started a new business | Newly formed LLC |
| Hired employees | Existing business hiring staff |
| Banking purpose | Bank requires EIN |
| Changed organization type | Sole proprietor becomes corporation |
| Purchased active business | Acquired operating company |
| Created trust | New trust requiring EIN |
| Created pension plan | Qualified plan |
| Other | Applicable special reason |
The reason should reflect the actual transaction.
Do not choose “banking purposes” simply because you eventually plan to open a bank account if the actual reason is that you formed a new operating business.
Do You Need an Operating Agreement for an EIN?
Usually, no operating agreement is uploaded as part of the standard EIN application.
However, an LLC operating agreement can still be useful because it helps establish:
- Ownership
- Management structure
- Responsible party
- Member count
- Company authority
Keep it with your business records even if the IRS EIN application does not request a copy.
Do You Need Articles of Organization for an EIN?
For a standard online EIN application, you generally are not asked to upload the Articles of Organization.
But an LLC should be formed first.
Your Articles of Organization or Certificate of Formation help you correctly enter:
- Legal entity name
- State of formation
- Formation date
- Ownership structure
This is why the document should be beside you even when it is not electronically submitted.
Do You Need a Business License Before Applying for an EIN?
Usually not.
An EIN is a federal taxpayer identification number, while business licenses are generally issued separately by state or local authorities.
Depending on the business, the usual sequence may be:
Form entity → obtain EIN → register tax accounts → obtain applicable licenses → open banking/payroll systems.
Exact state and local requirements can differ.
Do You Need a Business Bank Account Before Getting an EIN?
No.
In many cases, the sequence is the opposite.
Banks frequently ask for the EIN when opening a business account.
Once issued, an EIN can generally be used immediately for many business purposes, including opening an account or applying for business licenses. Some IRS electronic systems can take up to approximately two weeks to recognize a newly issued EIN.
Applying for an EIN Online
For eligible U.S.-based businesses, online EIN application is normally the fastest option.
Current IRS eligibility generally requires:
| Requirement | Online Eligibility |
|---|---|
| Domestic organization | Yes |
| Principal business location in U.S./territory | Required |
| Responsible party | Must be identified |
| Responsible party SSN/ITIN | Required |
| Complete in one session | Yes |
| Save and return later | No |
| IRS application fee | $0 |
If the application is approved, the EIN can generally be issued immediately online. The IRS recommends saving or printing the EIN confirmation letter at that time.
How Much Does an EIN Cost?
The IRS does not charge a fee to issue an EIN.
If a website asks you to pay $50, $100, or another amount, that is likely a third-party service fee—not an IRS EIN fee.
Using a paid filing service is optional.
Applying directly through the IRS is free.
EIN Application by Fax
Businesses that cannot or do not use the online process may submit Form SS-4 by fax.
The form must be completed carefully because the IRS uses the information to establish the entity’s federal tax account.
Applicants should keep a copy of the completed Form SS-4 with their permanent business records.
EIN Application by Mail
Form SS-4 can also be submitted by mail.
This method generally takes considerably longer than an eligible online application.
IRS guidance recommends applying sufficiently early when the EIN will be needed for filing a tax return, making a federal tax deposit, or completing another deadline-sensitive transaction.
One EIN Per Responsible Party Per Day
The IRS limits EIN issuance to one EIN per responsible party per day.
The restriction applies across application methods, including:
- Online
- Telephone
- Fax
Submitting through a different method does not bypass the daily limit. IRS
This is particularly relevant to business-formation services creating multiple entities for the same owner.
Does Every New Business Need a New EIN?
No.
Whether a new EIN is needed depends on whether the underlying ownership or legal structure has changed.
For example, a new EIN can be required when a sole proprietorship:
Incorporates, or
Becomes a partnership.
Each separate corporation generally requires its own EIN.
A simple business name or address change does not automatically mean you should request another EIN.
Already Have an EIN? Do Not Automatically Apply Again
Before requesting a new EIN, check whether the same entity already received one.
This can happen when:
- A previous accountant applied
- A formation company applied
- The company was dormant
- Ownership changed
- The confirmation letter was lost
- The founder forgot an earlier application
Form SS-4 specifically asks whether the applicant has previously received an EIN.
Creating unnecessary duplicate EINs can complicate tax records.
Third-Party Designee: Can Someone Apply for You?
An authorized third party can assist with an EIN application.
However, that is different from identifying a nominee as the responsible party.
The real responsible party must still be disclosed.
For Form SS-4 applications, the third-party designee section can authorize someone to receive the EIN and answer questions related to the application.
Examples can include an:
- Accountant
- Attorney
- Tax professional
- Authorized formation representative
The third party should not substitute their own identity for the actual owner or controlling individual.
Common EIN Application Mistakes
Applying Before Your LLC or Corporation Is Formed
If you plan to create a state legal entity, complete the state formation first.
Otherwise, the name or formation information on the EIN may not match the legal entity.
Entering a Registered Agent as the Responsible Party
Your registered agent is not automatically the person who controls your business.
The responsible party generally must be the person with ultimate ownership or effective control.
Using the DBA as the Legal Name
Enter the actual entity name on the legal-name field and the trade name separately.
Typing the Wrong SSN or ITIN
A simple digit error can prevent electronic verification.
Applying for Multiple EINs
Do not request another EIN simply because you cannot locate an earlier confirmation notice.
First determine whether the entity already has a number.
Applying Through a Paid Website Without Realizing the IRS Is Free
Third-party services may charge for preparing the application. The federal EIN itself is free.
Selecting the Wrong Entity Type
LLC is a state legal structure, but an LLC may have different federal tax classifications.
Do not confuse legal entity type with federal tax treatment.
Using a Nominee Instead of the Actual Responsible Party
The IRS specifically prohibits nominees from being treated as the true responsible party.
A 5-Minute EIN Application Accuracy Check
Before clicking submit or sending Form SS-4, verify this information:
| Check | Confirm |
|---|---|
| Legal name | Matches formation document exactly |
| Trade name | Listed separately if applicable |
| Entity type | Correct |
| State formation | Correct jurisdiction |
| Formation/start date | Accurate |
| Mailing address | Complete |
| Physical address | Correct |
| Responsible party | Actual controlling person |
| SSN/ITIN | Accurate where required |
| LLC member count | Correct |
| Accounting year-end | Correct |
| Employee estimate | Reasonable |
| Business description | Specific |
| Previous EIN | Answered accurately |
A few minutes of verification is easier than correcting an EIN account after submission.
After You Receive Your EIN
Save the EIN confirmation permanently.
Businesses commonly need it when dealing with:
| Business Activity | EIN May Be Needed |
|---|---|
| Business bank account | Yes |
| Federal tax returns | Yes |
| Payroll | Yes |
| Business credit | Often |
| Licenses and permits | Often |
| Merchant processors | Sometimes |
| Vendor onboarding | Sometimes |
| Retirement plans | Often |
| Certain state registrations | Often |
Although a newly issued EIN can be used immediately for many business purposes, the IRS notes that some electronic systems may take up to two weeks to recognize it for functions such as electronic tax filing, electronic tax payments, and TIN matching.
What If Your Business Address or Responsible Party Changes Later?
You do not normally obtain a new EIN simply because the business moves or the responsible party changes.
The IRS uses Form 8822-B, Change of Address or Responsible Party – Business, to report applicable changes.
A change in responsible party must generally be reported to the IRS within 60 days. IRS
EIN Application Requirements by Business Type
| Applicant | Key Requirement |
|---|---|
| Sole proprietor | Owner information and SSN/ITIN |
| Single-member LLC | LLC details and responsible party |
| Multi-member LLC | LLC information, member count, responsible party |
| Corporation | Formation data and principal officer |
| Partnership | Partnership information and general partner |
| Nonprofit | Legally form organization before EIN |
| Estate | Decedent and executor information |
| Trust | Trust and responsible-party details |
| Foreign-owned U.S. business | Form SS-4 may be needed if online requirements aren’t met |
| Foreign entity | International EIN process may apply |
Frequently Asked Questions About EIN Application Documents
What documents are required to apply for an EIN?
Most domestic online EIN applicants do not upload supporting documents. You primarily need your legal business name, entity type, business address, formation details, responsible-party information, SSN or ITIN, business start date, employee information, and business activity.
Keep formation documents available so the information entered matches the entity’s legal records.
Do I need my LLC documents to apply for an EIN?
You should form the LLC first and keep the formation documents available for reference. The standard IRS online EIN process generally does not require you to upload the Articles of Organization.
Do I need an operating agreement to get an EIN?
Usually not. An operating agreement can help verify ownership and management, but it is not normally uploaded during a routine EIN application.
Can I apply for an EIN without an SSN?
It can be possible in certain foreign-applicant situations. The standard online EIN application generally requires the responsible party’s SSN or ITIN. Form SS-4 instructions provide procedures for responsible parties who do not have and are ineligible for an SSN or ITIN. IRS
Can a foreigner get an EIN?
Yes. Foreign individuals and foreign-owned businesses can obtain EINs when they qualify or need one. Applicants who cannot use the domestic online system may need to use the IRS international application process.
Do I need an ITIN before getting an EIN?
Not universally. A responsible party generally needs an SSN or ITIN to use the domestic online EIN application. Certain foreign responsible parties who do not have and are ineligible for either can follow Form SS-4 instructions instead.
Does an LLC automatically come with an EIN?
No.
State LLC formation and federal EIN issuance are separate processes.
Form the LLC with the state first, then obtain its EIN when needed.
Is an EIN the same as an SSN?
No.
An SSN identifies an individual for Social Security and tax purposes.
An EIN generally identifies a business or other entity for federal tax and reporting purposes.
Is an EIN the same as an ITIN?
No.
An ITIN is an Individual Taxpayer Identification Number used by certain individuals who need a U.S. taxpayer identification number but are not eligible for an SSN.
An EIN identifies a business or other eligible entity.
Does an EIN expire?
An EIN generally remains associated with the entity to which it was assigned. You should not apply for a replacement EIN simply because the business has been inactive.
Certain structural or ownership changes can require a new EIN.
How long does it take to get an EIN online?
Eligible applicants can generally receive an EIN immediately after the IRS successfully validates the online application.
How much does an EIN application cost?
The IRS charges $0 to obtain an EIN directly.
Private companies may charge service fees to prepare or submit an application, but those are not government EIN fees.
Can I use my EIN immediately?
Generally, yes, for many business purposes. Some IRS electronic functions can take up to approximately two weeks before the new EIN is recognized.
Can my accountant apply for my EIN?
An appropriately authorized third-party designee can assist with the EIN application. However, your accountant should not be falsely identified as the business’s responsible party unless that person actually meets the responsible-party definition.
Do I need an EIN to open a business bank account?
Many banks require an EIN for corporations, partnerships, and LLC business accounts. Requirements can differ by financial institution and entity type.
Can I get more than one EIN in one day?
The IRS currently limits issuance to one EIN per responsible party per day, regardless of the application method.
Documents Required for EIN Application: Final Checklist
The most important thing to understand is that an EIN application usually requires accurate business information rather than a large package of uploaded documents.
Before applying in 2026 or 2027, make sure you have your legal entity information, formation records, business address, responsible-party details, taxpayer identification information, start date, employee information, and business activity ready.
For an LLC or corporation, form the entity with the state first.
For a domestic online application, the responsible party generally needs an SSN or ITIN.
For a foreign owner who does not have and is not eligible for either, the current Form SS-4 instructions provide a separate path that may allow “foreign” or “N/A” in the responsible-party taxpayer identification field.
And remember one detail that can save both time and money:
The IRS EIN application itself is free.
The current federal EIN process in 2026 uses the December 2025 revision of Form SS-4, so businesses applying in 2027 should confirm that they are using the latest IRS version before submitting a paper, fax, or international application.
