How Long Does It Take to Get an EIN?
Typical EIN Processing Times (By Application Method)
How long it takes to get an EIN (Employer Identification Number) depends mainly on how you apply and whether the information matches IRS validation checks. In most cases, the fastest option is applying online, while mailed and faxed submissions take longer due to manual handling and processing queues.
Online EIN Application
- Typical time: Often issued immediately after completing the online application.
- When you receive it: On-screen confirmation at the end of the session, with the ability to save/print the EIN confirmation notice.
- Best for: Applicants who can complete identity and entity validation during the session and have all required details ready.
Fax EIN Application
- Typical time: Usually several business days to a few weeks, depending on processing volume and whether the submission is complete.
- When you receive it: Returned by fax (if a fax number is provided) or by mail.
- Best for: Applicants who cannot use the online system or need to submit via a signed paper form.
Mail EIN Application
- Typical time: Often several weeks.
- When you receive it: By mail only.
- Best for: Applicants who prefer paper filing and can accommodate longer timelines.
Phone EIN Application (Limited Use)
- Typical time: Can be same-day for certain international applicants when eligible.
- When you receive it: Provided during the call, followed by written confirmation.
- Best for: Applicants without a U.S. principal business location or without a Social Security Number/ITIN when permitted.
What “Getting an EIN” Really Means
An EIN is considered “received” when it is assigned and you have the EIN confirmation (often called the EIN assignment notice). Many banks, payroll providers, and state agencies accept the EIN as soon as it is assigned, but they may still require the confirmation notice for onboarding.
Factors That Can Slow Down EIN Issuance
Even when applying online, EIN issuance can be delayed or blocked if the IRS system cannot validate key details or if the submission triggers a manual review. Common causes include:
- Mismatched responsible party information (name/SSN/ITIN not matching IRS records).
- Entity type confusion (selecting the wrong structure for an LLC, corporation, partnership, or nonprofit).
- Inconsistent business start date or an unusual “reason for applying” selection that doesn’t fit the entity.
- Prior EIN history (for example, attempting to obtain a new EIN when a prior EIN should be reused).
- System availability (the online system may be unavailable during maintenance windows).
How to Prepare So You Get an EIN Faster
Having your information ready before you begin reduces errors and rework. Prepare the following items:
- Legal name of the entity (exactly as formed/registered)
- Trade name/DBA (if applicable)
- Entity type and state of formation
- Responsible party name and taxpayer identification number
- Business address and mailing address
- Business start date and principal activity
- Reason for applying (new business, hiring employees, banking requirements, etc.)
If you’re planning to submit an application through an online intake workflow, you can use an online EIN request form to organize details before submission.
When You’ll Need the EIN (Timing Considerations)
Even if you receive an EIN quickly, your overall setup timeline may depend on what you need to do next. Common situations where timing matters include:
- Opening a business bank account: Many banks require the EIN confirmation notice and formation documents.
- Running payroll: Payroll providers and tax registrations may require the EIN to be active in their systems before the first pay run.
- Applying for state tax accounts: Some state registrations can be started quickly once the EIN is assigned. For example, businesses operating in Oklahoma may also need an Oklahoma sales tax number depending on what they sell.
- Vendor onboarding and 1099/W-9 workflows: Some partners request the EIN before contracting or issuing payments.
Is an EIN Available Immediately After You Form an LLC or Corporation?
Formation and EIN issuance are separate steps. You can often apply for an EIN shortly after forming the entity, but the best timing depends on:
- Whether your state formation has been accepted and the legal name is finalized
- Whether you have a responsible party with a valid taxpayer identification number
- Whether you need the EIN under the entity’s exact legal name (recommended for banking and tax consistency)
What to Do If You Need an EIN Urgently
- Use the online method when eligible: This is typically the fastest route to immediate issuance.
- Double-check responsible party details: Small mismatches can force a manual process.
- Keep a clean copy of your confirmation: Save the EIN assignment notice for banks, payroll, and state registrations.
- Avoid unnecessary duplicate requests: If an EIN already exists for the entity, a second request can create confusion and delays.
FAQ: How Long Does It Take to Get an EIN?
1) Can I get an EIN the same day?
Yes. If you apply online and the submission validates successfully, the EIN is commonly issued immediately during the same session.
2) How long does it take to get an EIN if I apply by mail?
Mail submissions typically take several weeks because they must be received, opened, routed, and processed manually before the EIN is assigned and mailed back.
3) How long does it take to get an EIN if I apply by fax?
Fax applications often take several business days to a few weeks, depending on processing volume and whether the form is complete and readable.
4) If I receive my EIN online, is it active immediately for banking and payroll?
The EIN is assigned immediately, but some banks and providers may require the printed confirmation notice and may take additional time to complete their own verification and onboarding steps.
5) Why would an online EIN application not issue instantly?
Instant issuance can fail when the system cannot validate responsible party details, the entity selection doesn’t match the facts, or the application triggers a manual review due to inconsistencies.
6) Do I need to wait for my state to approve my LLC before applying for an EIN?
It’s best to apply once the entity name and structure are finalized. This helps ensure the EIN is tied to the correct legal name and reduces issues when opening accounts or registering for taxes.
7) Can I apply for an EIN before I hire employees?
Yes. Many businesses obtain an EIN early for banking, vendor setup, or to prepare for payroll and tax registrations before the first hire.
8) How long after getting an EIN can I register for state tax accounts?
Many state registrations can be started as soon as the EIN is assigned, but the overall timeline depends on the state’s processing time and the type of tax account being opened.
9) What information causes the most EIN delays?
The most common delay triggers are responsible party name/ID mismatches, incorrect entity type selection (especially for LLCs), and incomplete or inconsistent addresses and start dates.
10) If I lost my EIN confirmation, does that change how long it takes to use my EIN?
Losing the confirmation doesn’t change the EIN assignment date, but it can slow down banking or onboarding if a third party requires the notice. Replacing documentation can add time to your setup process.
