Complete·5/22/26

Louisiana HB633 modifies deadlines, penalty calculations, and exceptions for estimated tax payments.

HB633 amends Louisiana's tax code to adjust deadlines for filing applications for estimated tax adjustments, changing the deadline from the 15th day of the fourth month to the 15th day of the fifth month. It also repeals certain penalty calculations for underpayments of estimated taxes, replacing them with a new method. The bill retains the exception for taxpayers who pay an estimated tax amount equal to 80% of the current year's tax. These changes apply to tax periods beginning on or after January 1, 2026.
