Federal Income Tax Deduction

Louisiana is one of the few states that allows taxpayers to deduct their federal income tax payments from their state taxable income. This can significantly reduce your Louisiana tax liability.

Note: This calculator provides a simplified estimate and does not fully implement the federal income tax deduction, which would require a more complex calculation.

Parish Taxes

Louisiana does not have local income taxes imposed by parishes (counties). However, parishes do levy sales and property taxes that can vary widely.

Federal Income Tax

Your federal income tax is calculated based on federal tax brackets, your filing status, deductions (standard or itemized), and allowances claimed on your W-4 form. Pre-tax deductions like 401(k) or HSA contributions reduce your federal taxable income.

FICA Taxes (Social Security & Medicare)

FICA taxes fund Social Security and Medicare. These are typically withheld by employers.

• Social Security: 6.2% on income up to the annual limit ($168,600 for 2024).
• Medicare: 1.45% on all income. An additional 0.9% Medicare tax applies to income above certain thresholds ($200,000 for Single, $250,000 for MFJ).
