Louisiana‘s tax system ranks 40th overall on the 2025 State Tax Competitiveness Index. Louisiana’s tax code is a national outlier, with one of the most complicated sales tax regimes and a long list of unusual and uncompetitive taxes and tax provisions, like inventory taxes and a capital stock (franchise) tax. Individual taxpayers are subject to three tax brackets and a competitive top marginal rate of 4.25 percent. However, the individual income tax code is not indexed for inflation, which means Louisiana taxpayers are subject to bracket creep (i.e., when inflation pushes a taxpayer from a lower bracket to a higher one when nominal income rises, but due to inflation, real income does not, or may even decline). Moreover, unlike other states with an individual income tax, Louisiana does not currently recognize S corporation status, requiring these entities to file taxes as C corporations rather than enjoying the pass-through status accorded to them in other states.
Businesses are subject to a franchise tax on their net worth (or accumulated wealth), which penalizes investment and is imposed regardless of profitability. Louisiana does not cap maximum payments for these taxes, making an already uncompetitive tax even more detrimental. Louisiana also taxes business inventory, which, like the capital stock tax, is imposed regardless of business profitability. These taxes are nonneutral, disproportionately affecting those businesses with larger inventories and causing taxpayers to make inefficient timing and location decisions with their inventory.
Like the state’s individual tax code, the corporate tax rates are not indexed for inflation.
Perhaps most notably, Louisiana is highly unusual in lacking central collections and administration of its sales tax. The state has made progress with an alternative remote sellers regime, but parishes’ and other jurisdictions’ ability to define their own tax bases and to administer the taxes separately from the state imposes high compliance costs.
Thirty-nine states will begin 2025 with notable tax changes, including nine states cutting individual income taxes. Recent years have seen a wave of significant tax reforms, and the changes scheduled for 2025 show that these efforts have not let up.
Tax avoidance is a natural consequence of tax policy. Policymakers should consider the unintended consequences, both to public health and public coffers, of the excise taxes and regulatory regimes for cigarettes and other nicotine products.
Many policies, such as minimum wage levels, tax brackets, and means-tested public benefit income thresholds, are denominated in nominal dollars, even though a dollar in one region may go much further than a dollar in another. Lawmakers should keep that reality in mind as they make changes to tax and economic policies.
