The Louisiana Department of Revenue collects sales tax on product and service transactions throughout the state of Louisiana. The way the system works is that a Louisiana business registers to get a sales tax certificate. The department then sends forms out to the businesses. Those businesses then collect the Louisiana sales tax from their customers and send it to the Department of Revenue.
Go to the Louisiana Secretary of State’s “Corporation Forms” page at sos.louisiana.gov/tabid/814/Default.aspx. Look through the list of forms to see if you need to do a Louisiana business registration with this office. Generally speaking, the following types of business entities must file with the Secretary of State: limited liability companies, corporations, partnerships and limited liability partnerships. If you register, you will have a Louisiana business name. File for your Louisiana sales tax permit (certificate) and other business tax and related filings using that registered business name.
See about EIN requirements. An EIN is a federal employer identification number, which is typically required for businesses with employees that earn wages and all nonprofits and certain other product sellers. To find out whether you need such a number, just go to the IRS.gov website and enter “EIN requirements” in the search box at the top of the page. Read the information to see if you need a number.
File to get a Louisiana sales tax certificate if you sell products and services in the state. See below on how to apply for this Louisiana sales tax account.
Open the “Sales Taxes” page on the Louisiana Department of Revenue website at revenue.louisiana.gov/sections/business/sales.aspx. On this page, you need to find two kinds of information: the current Louisiana sales tax rate and the kinds of transactions that are subject to Louisiana sales tax. While the standard rate is 4 percent, there are some exceptions.
Note that you may also have to pay local Louisiana sales taxes. See below for a registration form.
Get periodic Louisiana sales tax returns. Make sure you submit these returns by the 20th of the month following the month in which you collected the taxes. Some Louisiana businesses need to file monthly, while others file quarterly.
