How Louisiana taxes your income
Louisiana taxes income at a single rate of 3%. Because there is one rate, your state effective rate stays close to 3% as income rises once deductions are used up.
We subtract an estimated $12,875 (the state standard deduction plus any dollar-amount personal exemption) from your income before applying the Louisiana brackets.
Not modelled: personal tax credits, most income-based phase-outs, deductibility of federal tax where a state allows it, local income taxes (for example city or county taxes), and state payroll taxes such as disability or family-leave contributions.
