Louisiana Made Real Progress on Taxes. Then There's the Sales Tax.

Louisiana's tax reform story over the last two years is one worth telling. The 2024 special session produced genuine, structural change: a flat 3% individual income tax, a reduced corporate rate of 5.5%, the elimination of the corporate franchise tax, and permanent full expensing — making Louisiana one of only three states in the country to fully decouple from federal phasedown rules on business investment. The Tax Foundation took notice. Louisiana jumped six spots in its State Tax Competitiveness Index, landing at 31st overall. For a state that has spent decades near the bottom of every business climate ranking, that is meaningful movement.

But buried in that same report is a number that every business owner in Louisiana already knows in their bones: the state still ranks 50th in the nation on sales taxes. Dead last.

That distinction is not just an accounting inconvenience. It is a structural drag on competitiveness that the income tax reforms, as significant as they were, cannot fully offset.

The Problem Is the System, Not Just the Rate

Louisiana carries the highest average combined state and local sales tax rate in the country at 10.11%. That alone would be notable. But the more fundamental issue is how those taxes are collected.

While virtually every other state runs sales tax collection through a centralized, state-level system, Louisiana operates through a parish-by-parish patchwork. Each of the state's 64 parishes maintains its own forms, rules, deadlines, and collectors. For a business operating across multiple parishes — or a national company evaluating whether to locate operations here — that means multiplying compliance costs that competitors in Texas, Florida, or Tennessee simply do not face.

The Tax Foundation put it plainly in its 2026 assessment: Louisiana is "highly unusual in lacking central collections and administration of its sales tax." That is a diplomatic way of saying that Louisiana is asking its businesses to carry a burden no other state imposes to the same degree.

Progress Has Been Made — and Stalled

To be fair, Louisiana has not been standing still. Legislators have tried before: in 2021, both chambers unanimously passed a constitutional amendment to create a centralized sales tax commission. Voters narrowly rejected it, 52-48, in a low-turnout election after some local officials raised concerns about local control.

The Legislature subsequently created the Louisiana Uniform Local Sales Tax Board, and in early 2026 rolled out a Combined State and Local Sales Tax Return designed to simplify compliance. That was a step forward. But the rollout also illustrated the limits of a halfway measure. The system launch was delayed from its January target. Early users reported system errors significant enough that tax practitioners were advising clients to file ahead of deadline to avoid penalties. Seven parishes still do not permit use of the combined return portal. And critically, payments must still be remitted separately to each individual taxing authority.

Louisiana now has a combined filing form with separate parish payments. That is better than what came before. It is not a solution.

HB 620 and the November Ballot

The cleaner fix is HB 620, a constitutional amendment moving through the current legislative session that would authorize the Legislature to establish a centralized collection system for all state and local sales and use taxes. Because the Louisiana Constitution currently grants local governments authority to collect their own taxes, a constitutional change is required before any full solution is possible.

If passed by two-thirds of both chambers, the amendment would go before voters in November. Importantly, the reform does not redirect a single dollar of local tax revenue — local governments would still receive everything they are owed. The only thing that changes is how the money moves.

For the business community, the case is straightforward. Centralized collection reduces compliance costs, levels the playing field with out-of-state competitors, and sends a signal to site selectors and investors that Louisiana is serious about being a place where businesses can operate without unnecessary friction.

The Broader Picture

Louisiana's overall tax reform trajectory is real and should be acknowledged. The state has done more in two years than it did in the previous two decades to position itself competitively. Personal income has grown faster than inflation since late 2022. U-Haul's 2025 Growth Index showed Louisiana climbing 13 spots in the ranking of states attracting new residents — a tangible signal that the reforms are having an effect.

But the Southern competition is not standing still. Mississippi is phasing its income tax toward zero. Arkansas has been cutting rates consistently. Georgia dropped its flat rate again this year. Tennessee has no income tax and a relatively streamlined tax administration.

Louisiana does not need to be perfect. It needs to be competitive. Finishing last in the nation on sales tax administration, in a region full of states actively courting the same investment dollars, is a problem that policy momentum and good intentions cannot paper over.

The income tax work was the right call. Fixing the sales tax system is the next one.
