Registration Requirements in Louisiana
Louisiana requires new businesses to register with the Louisiana Secretary of State, Louisiana Department of Revenue, and the Louisiana Workforce Commission. Louisiana has created a website for businesses to fulfill all their registration requirements. See the following link for more information.
S Corporation Tax
Louisiana does not recognize the federal S election. Therefore, S corporations in Louisiana must file and pay the states corporate income tax. The corporate tax for S corps is taken as a ratio of non-Louisiana residents vs. Louisiana residents. If all shareholders are Louisiana residents, S corporations will not owe corporate income tax. Each individual shareholder must pay state tax on his or her share of income.
Louisiana corporation income tax is based on marginal tax rates as follows:
S Corporations file annual returns on Form CIFT-620 Louisiana Corporation Income Tax
LLCs and partnerships are not required to pay Louisiana corporate franchise tax and corporate income tax. Instead, business income is split between LLC members and partnership partners, and who then pay state taxes on the amounts allocated to them. If all members of a partnership are natural Louisiana citizens, a Partnership return is not required to be filed. Partnerships with non residents will be required to file Form IT-565 - Partnership Return of Income
Corporate Franchise Tax
Louisiana corporation franchise tax is a net worth tax essentially imposed for the privilege of doing business in Louisiana. The basic breakdown is as follows:
- $1.50 for each $1,000 or major fraction thereof up to $300,000 of capital used in Louisiana; and
- $3.00 for each $1,000 or major fraction thereof in excess of $300,000 of capital used in Louisiana.
Partnerships engaging in business in Louisiana that have nonresident partners must file a composite partnership return. The only partnerships that are exempt from this have one of the following:
- All nonresident partners are corporations, partnerships, or tax exempt trusts; or
- All nonresident individual partners have a valid agreement on file with the Department of Revenue.
The composite return must be filed electronically and a tax rate of 6% is assessed on the total distributive shares for nonresident partners.

If your business was formed or is located in another state, but generates income in Louisiana, it may be subject to Louisiana taxes. The rules for taxation of multistate businesses, including what constitutes nexus with a state for the purpose of various taxes, are complicated. If you run such a business, you should consult with a tax professional.
