Get an EIN for Your Maryland LLC — Free at IRS.gov (2026)
An EIN identifies your LLC for federal tax purposes. The IRS issues it free. Whether you need one and which application route you can use depend on tax classification, employment, business location and the responsible party’s taxpayer ID. Maryland registrations are separate activity-based checks.
Form your Maryland LLC first. Online eligibility requires a U.S.-formed entity, a U.S./territory principal place of business, the responsible party’s SSN or ITIN and proper applicant authority. Other applicants use the appropriate SS-4 or international route. The IRS fee is $0; optional assistance costs separately. Check state accounts based on your activities.

When Your Maryland LLC Needs an EIN
An EIN is a federal business tax ID. Partnerships, corporations and LLCs with employees or certain excise-tax obligations generally need one. A disregarded single-member LLC without employees or excise-tax liability may not need its own EIN for federal tax purposes; a bank or state requirement can still make one useful or necessary.
Check your bank’s documents for ownership and authority. Do not assume every bank needs the same paperwork. For a disregarded LLC’s Form W-9, generally use the owner’s name and SSN or EIN, not the LLC’s EIN.
The IRS charges $0. Optional paid assistance has a separate fee and is not required to use an eligible IRS application route.

This picker gives route guidance, not an IRS eligibility determination. Online also requires a U.S.-formed entity and the responsible party or an authorized representative; a third-party designee needs signed authorization. It collects no taxpayer-ID numbers.
The Online Application, Step by Step
- Form the LLC first and use its approved legal name.
- Check the IRS online eligibility and current operating hours. Have the required company information ready.
- Identify the individual who ultimately controls the LLC and its assets. A formation nominee is not the responsible party.
- Complete the application in one session. If approved, the EIN is issued online; save the assignment notice.
- Use only one application method per entity. The IRS limits applications to one EIN per responsible party per day.
Form SS-4 and International Routes
Without the responsible party’s SSN or ITIN, use the appropriate Form SS-4 route. Enter “foreign” or “N/A” on line 7b only when that person lacks and is ineligible to obtain an SSN or ITIN.
For a legal residence, principal business, office or agency in a state or DC: fax to 855-641-6935, or mail to IRS, Attn: EIN Operation, Cincinnati, OH 45999. Otherwise: fax to 855-215-1627 from inside the U.S. or 304-707-9471 from outside; mail to IRS, Attn: EIN International Operation, Cincinnati, OH 45999. Include a return fax number. IRS estimates generally about four business days by fax and four weeks by mail; delays are possible.
The international phone route is available only if there is no legal residence, principal place of business, principal office or agency in the U.S. or U.S. territories. The number is 267-941-1099, Monday–Friday, 6 a.m.–11 p.m. Eastern, and is not toll-free. An overseas principal business or foreign ownership alone does not establish that eligibility.
Current IRS Form SS-4 instructionsIRS international applicant guidanceForeign-owned U.S. disregarded entities should check Form 5472 and the associated pro forma Form 1120 rules when reportable related-party transactions occur. Zero revenue does not by itself remove reporting obligations. Failure to file a required Form 5472 can bring a $25,000 penalty.
IRS Form 5472 requirements and penaltiesAfter You Get Your EIN — the Maryland Sequence
- Prepare for a business bank account — ask the bank which IRS confirmation, approved Articles, identification, ownership and signing-authority documents it accepts. An operating agreement may be requested. An EIN alone does not guarantee approval.
- Check applicable Maryland tax accounts — use the Comptroller’s current registration guidance for your sales, services and payroll. Register for withholding if required when hiring and for sales/use tax when your activities require it. An EIN does not create these accounts; follow the official registration checks below.
- Check licensing for your activities and location — a trader’s license may apply when buying goods for resale, subject to exceptions. Check state, county and municipal requirements in Step 7; an EIN is not a license.
- Calendar April 15 for Form 1 — and review MarylandSaves eligibility while you are in setup mode so any future waiver qualification is handled on time.
Ahmad Adil’s Take: Form the LLC first, choose your eligible IRS route and save the confirmation. Bank appointments and state registrations have separate requirements and processing times; plan them without assuming the whole sequence finishes in one day.

After Your EIN: Maryland Registration Checks
An EIN identifies your business for federal tax purposes. It does not automatically establish state tax accounts, an employer account or a business license. Choose registrations for the activities and locations of your LLC.
Form the LLC first, then use the eligible IRS application route. The IRS issues EINs free. Optional filing help has a separate fee.

Use the official Maryland tax guidance below to identify the accounts required for your sales, services and payroll. Register for applicable accounts rather than assuming an EIN completes state registration.

Check covered employment and registration timing using the state employer guidance below. Complete unemployment-insurance registration when required. Some states combine applications; follow their instructions instead of submitting duplicate requests.
Maryland employer registration guidanceLicenses and other employer obligations
Check state and local licensing for your activities. If hiring, also check new-hire reporting, workers’ compensation and applicable leave programs. A tax or unemployment account does not automatically complete these obligations.
