File Louisiana State Income Taxes
With variable income tax rates ranging between 2% and 4%, Louisiana has lower rates than most other states in the U.S. Their annual tax revenue is close to $9 billion, which is in the median range for the country.
Louisiana tax returns must be e-filed or mailed by May 15. Extension requests must also be postmarked by this date, and the final deadline for an extended return is November 15.
Taxpayers who need more time to file can visit the Louisiana Department of Revenue's site to file electronically. Any tax due that is unpaid after May 15 will be subject to penalty fees. To file an electronic payment with the extension request, use the electronic Form R-2868V.

If You do not File Louisiana Taxes on Time
Taxpayers who do not file a return on time will be charged a late fee of 5% of the tax for each 30 days it remains unpaid. If taxpayers file on time but do not pay the amount they owe in full by May 15, they will be charged 0.5% of the amount owed for each month it remains unpaid.
Estimated Tax Payments
Taxpayers who do not have enough money taken from their income or are self-employed may have to pay quarterly estimated taxes. Use Form IT-540ES to create vouchers for mailing payments. Taxpayers may also pay online or mail vouchers with payments to
