Louisiana does have a state income tax
Louisiana charges a state income tax on wages, business income, and other earnings. The tax rate depends on your income level — Louisiana uses a progressive system with multiple brackets, meaning higher earners pay a higher percentage. Unlike some states that have no income tax at all, Louisiana residents cannot avoid this tax by straightforward living in the state.
The state also taxes capital gains, retirement income, and certain other sources of money. However, Louisiana offers some deductions and exemptions that can lower your taxable income, which means you may not pay tax on every dollar you earn.
Key Takeaways
- Louisiana has five income tax brackets ranging from 2% to 5.75%, with the rate you pay depending on how much you earn.
- You must file a Louisiana state tax return if you earned income in the state, even if you do not owe federal tax.
- Louisiana allows deductions for federal income tax paid, mortgage interest, and charitable donations, which can reduce the amount you owe.
- Retirees may exclude some or all of their retirement income from state tax if they meet age and income requirements.
- The Louisiana Department of Revenue handles state tax collection and can answer questions about your specific situation.
Louisiana's income tax brackets and rates
Louisiana's income tax system has five tax brackets. The lowest rate is 2% on the first portion of your income, and the highest is 5.75% on income above a certain threshold. The exact dollar amounts where each bracket begins change each year based on inflation adjustments.
For example, a single filer in 2024 pays 2% on income up to roughly $12,500, then 4% on income between $12,500 and $50,000, then higher rates as income increases. A married couple filing jointly has higher income thresholds before moving into each bracket. The brackets are adjusted annually, so the exact numbers shift from year to year.
Your filing status — single, married filing jointly, married filing separately, or head of household — determines which bracket applies to your income. You can find the current year's brackets on the Louisiana Department of Revenue website or on your tax forms.
Who has to file a Louisiana state return
You must file a Louisiana state tax return if you earned income in Louisiana and your income exceeds the filing threshold for your situation. The threshold depends on your age, filing status, and type of income. Even if you do not owe federal tax, you may still owe Louisiana tax.
If you worked in Louisiana but live in another state, you generally still owe Louisiana tax on the income you earned there. Some people who work across state lines can claim a credit on their Louisiana return for taxes paid to another state, which prevents you from being taxed twice on the same income.
Self-employed people, business owners, and freelancers must file if their net business income exceeds the threshold. If you received a W-2 from an employer, your employer likely withheld Louisiana tax from your paychecks, but you still need to file to report all your income and claim any deductions you are may have access to to.
Deductions and exemptions that lower your Louisiana tax bill
Louisiana allows you to deduct federal income tax you paid during the year, which is one of the largest deductions available. You can also deduct mortgage interest, property taxes, charitable donations, and certain other expenses if you itemize rather than take the standard deduction.
Retirement income receives special treatment in Louisiana. If you are 59½ or older, you may exclude some or all of your retirement income from state tax, depending on the source and your total income. This includes distributions from IRAs, 401(k)s, pensions, and annuities. The amount you can exclude phases out as your income rises, so higher earners may not receive the full benefit.
Military retirement pay is also exempt from Louisiana state tax, regardless of your age. If you are a veteran receiving military pension payments, you do not report that income on your Louisiana return.
How to file your Louisiana state tax return
You can file your Louisiana return on paper by mailing Form IT-540 (the individual income tax return) to the Louisiana Department of Revenue, or you can file electronically through the state's online system or through tax software that supports Louisiana returns.
The filing important date is typically April 15 of the year following the tax year, the same as the federal important date. If you cannot file by that date, you can request an extension, which gives you until October 15 to file without penalty — though any tax you owe is still due by April 15.
If you use tax software like TurboTax, H&R Block, or TaxAct, those programs can file your Louisiana return electronically at the same time you file federal. If you use a tax professional or CPA, they can file for you. The Louisiana Department of Revenue website lists approved software providers and tax preparers.
What happens if you do not file or pay
If you owe Louisiana tax and do not file or pay, the state charges penalties and interest. The failure-to-file penalty is typically 5% of the unpaid tax per month, up to 25%. The failure-to-pay penalty is 0.5% per month. Interest accrues daily on any unpaid balance.
If you owe a significant amount, the Louisiana Department of Revenue can place a lien on your property, garnish your wages, or intercept your state or federal refunds to collect the debt. The longer you wait, the larger the total amount owed becomes.
If you cannot pay the full amount, you can contact the Louisiana Department of Revenue to discuss a payment plan. The state may also offer an offer in compromise in some cases, which allows you to settle for less than the full amount owed if you can show financial hardship.
Louisiana tax credits you may not know about
Beyond deductions, Louisiana offers tax credits that directly reduce the amount of tax you owe. A credit is more valuable than a deduction because it reduces your tax dollar-for-dollar rather than just reducing your taxable income.
The Earned Income Tax Credit (EITC) is available to low- and moderate-income workers. Louisiana's version of this credit is based on the federal EITC, so if you claim it on your federal return, you can also claim it on your Louisiana return. The credit amount depends on your income and number of dependents.
Other credits include the Child and Dependent Care Credit, the Education Credit, and the Residential Energy Credit for certain home improvements. You can find a complete list of available credits in the Louisiana tax instruction booklet or on the Department of Revenue website.
Frequently Asked Questions
Does Louisiana tax Social Security benefits?
No. Louisiana does not tax Social Security benefits, even if they are your only income. However, other retirement income like pensions and IRA distributions may be taxable unless you meet the age and income requirements for the retirement income exclusion.
What if I moved to Louisiana partway through the year?
You owe Louisiana tax only on income you earned while you were a resident. If you moved in June, you report only the income from June through December on your Louisiana return. You may also owe tax to the state you moved from on income earned there earlier in the year.
Can I claim my spouse as a dependent on my Louisiana return?
No. You cannot claim your spouse as a dependent on any tax return, federal or state. You can only claim dependents who are children, grandchildren, parents, or other may have access to relatives.
Is there a penalty for filing late if I do not owe tax?
If you do not owe Louisiana tax, there is no penalty for filing late. However, if you are owed a refund, filing late delays when you receive it. The state does not pay interest on refunds, so filing sooner gets your money back faster.
Where do I send my Louisiana tax return if I file by mail?
Mail your return to the Louisiana Department of Revenue at the address listed in the tax instruction booklet. The address depends on whether you are enclosing a payment. Do not send your return to the federal IRS address — it must go to the Louisiana office.
