Get an EIN for Your Louisiana LLC — Free at IRS.gov (2026)
Your EIN is your LLC's federal tax ID — required for banking, hiring, and registering with the Louisiana Department of Revenue. It's 100% free at IRS.gov and takes about 15 minutes. Here's the Louisiana-specific sequence, including the no-SSN path.
Apply for your EIN free at IRS.gov — never pay a third party. With an SSN or ITIN, the online application takes about 15 minutes and issues your EIN immediately. Without one, file Form SS-4 by fax (≈4+ business days) or mail (≈4+ weeks). Apply after your Louisiana Articles are approved so IRS records match your exact legal name and anniversary date. Then take the EIN to the Louisiana Department of Revenue (via geauxBIZ/LaTAP) to register for state taxes.

What an EIN Is (and Why Every Louisiana LLC Needs One)
An EIN (Employer Identification Number) is the nine-digit federal tax ID the IRS assigns your business — its Social Security number, in effect. You need one even if you'll never hire anyone:
- Open a business bank account — every bank requires the EIN letter alongside your certified Articles and operating agreement.
- Register with the Louisiana Department of Revenue — your LDR accounts (income withholding, sales tax) key off the EIN.
- File federal and state taxes — and parish sales tax registrations reference it too.
- Protect your SSN — hand clients your EIN on W-9s instead of your personal number.
Never pay for an EIN. The IRS charges nothing. Sites charging $50–$300 for "EIN filing" are reselling a free government form, often dressed up to look official. The only site you need is IRS.gov.

2 questions · your exact path, timeline, and Louisiana next step
The IRS online assistant runs Mon–Fri during posted hours and issues one EIN per responsible party per day. All methods are free.
The Online Application, Step by Step
Wait for full approval first
In Louisiana that means the Articles + Initial Report are approved and the agent acknowledgment is in — your legal name and anniversary date must be final.
Go to the IRS EIN Assistant
IRS.gov → "Apply for an Employer ID Number." Choose "Limited Liability Company," then Louisiana.
Enter members and responsible party
Member count sets your default tax classification (disregarded entity for one, partnership for two-plus). Community-property note: a husband-wife LLC in Louisiana may qualify to elect qualified-joint-venture-style disregarded treatment — ask your CPA which classification fits before answering.
Complete in one session
The application times out after 15 idle minutes and can't be saved. Keep your Articles in front of you.
Download the CP 575 immediately
Your confirmation letter appears once. Banks and the LDR will want it; replacing it means calling the IRS for Letter 147C.
No SSN? You Can Still Get an EIN
Non-US founders complete Form SS-4, write "Foreign" on line 7b, and submit by fax (~4+ business days) or mail (~4+ weeks). Line-by-line help in our guides to EINs without an SSN and foreign-owned LLCs. Foreign-owned single-member LLCs: don't forget Form 5472 — the penalty is $25,000 even at zero income.
After You Get Your EIN — the Louisiana Sequence
- Open your business bank account — CP 575, certified Articles, operating agreement.
- Register with the Louisiana Department of Revenue — through geauxBIZ or LaTAP, setting up income/withholding accounts and your state sales tax account if you sell taxable goods or services.
- Register with your parish collector(s) for local sales tax if applicable — Louisiana administers local sales tax at the parish level (see Step 7).
- Calendar your anniversary date for the $30 annual report.
Ahmad Adil's Take: the EIN itself is identical in all 50 states — free, 15 minutes, IRS.gov, done. What's different in Louisiana is what comes after: most states have one tax registration; Louisiana has the LDR plus parish-level sales tax collectors. Founders who stop at the EIN and skip the LDR/parish registrations discover the gap at their first sales tax deadline. Do the whole chain in one sitting — EIN, bank, LDR, parish — and you'll never think about it again.
