geauxBIZ gives access to the Secretary of State, the Department of Revenue and the Louisiana Workforce Commission (shown on the site as Louisiana Works) in one place, so a business can file its LLC, register for a Louisiana tax account number and apply for an unemployment insurance account number together.
Getting an EIN or registering with the Secretary of State does not open a Louisiana withholding account. The Department of Revenue says to register for withholding on LaTAP only when you begin withholding Louisiana income tax from employees, because registering early can create filing requirements.
If you register on paper with Form R-16019 instead of online, the Louisiana Department of Revenue requires a copy of your IRS EIN letter, such as the CP 575 notice or Letter 147C, to be included with the application.
Louisiana businesses collect both state and parish or city sales taxes. Local sales tax account numbers come from the local taxing authorities, and the Department of Revenue's Parish E-File can submit the state and local sales tax returns together.
Also on the Louisiana list
- Register with the Louisiana Department of Revenue for a Louisiana Revenue Account Number, through geauxBIZ or LaTAP, for the state tax accounts the business needs. An LLC that makes taxable sales also needs a local sales tax account number from the parish collector.
- File the annual report with the Secretary of State through geauxBIZ on or before the anniversary date of the LLC's organization every year.

What is different about Louisiana
- A Louisiana LLC is formed by filing two documents together, the Articles of Organization and an Initial Report. The Initial Report gives the registered office and agents and must include a notarized affidavit of acknowledgment and acceptance signed by each registered agent; if the members or managers are not named in it, a supplementary report follows once they are chosen.
- Louisiana's constitution requires sales taxes levied by parishes, cities and other local governments to be collected by a single collector in each parish, not by the Department of Revenue. A Louisiana LLC that collects sales tax therefore holds a state account plus a local account number issued by the parish collector's office, and the Department of Revenue's Parish E-File system lets it file the state return and several parish returns from one site.
- geauxBIZ is run jointly by the Secretary of State, the Department of Revenue and the Louisiana Workforce Commission, so one online registration can form the LLC, register for a Louisiana tax account number and apply for an unemployment insurance account number. The Department of Revenue's paper application for a Revenue Account Number asks for both the EIN and the Louisiana charter number, tying the state tax account to the Secretary of State record.
Before you apply
The SS-4 must match the Louisiana Secretary of State filing; its charter number is a state index, not a tax ID.
Married couple as the only owners? Louisiana is a community property state, so the LLC can be treated as a disregarded entity rather than a partnership that files a return every year. The choice is made on the SS-4, and our application asks about it.
Louisiana EIN questions
How do I get an EIN number in Louisiana?
File IRS Form SS-4 after the Louisiana Secretary of State approves any formation filing; there is no Louisiana EIN application. geauxBIZ gives access to the Secretary of State, the Department of Revenue and the Louisiana Workforce Commission (shown on the site as Louisiana Works) in one place, so a business can file its LLC, register for a Louisiana tax account number and apply for an unemployment insurance account number together.
Is there a Louisiana EIN or state tax ID number?
No; only the IRS issues EINs (also called the FEIN or federal tax ID). Louisiana's own numbers are the charter number from the Louisiana Secretary of State, the Louisiana Revenue Account Number from the Louisiana Department of Revenue, the unemployment insurance account number (EAN) from the Louisiana Workforce Commission, and the sales tax account from the Louisiana Department of Revenue.
Is the Louisiana Revenue Account Number the same as my EIN?
No. The Louisiana Department of Revenue assigns it when you register as an employer in LaTAP, and it is 10 or 12 digits. It goes in W-2 box 15; the EIN goes in box b.
Where do I register for Louisiana unemployment insurance?
With the Louisiana Workforce Commission. It assigns an unemployment insurance account number (EAN), 7 digits, a separate number from the EIN.
Do I need a Louisiana sales tax account?
Only if you sell what Louisiana taxes. The Louisiana Department of Revenue issues it through LaTAP, and your returns are filed under its number, not the EIN.
