Business, Professional & Occupational Licenses

BPOL taxes are levied by the Parish and the three municipalities located in the parish. These taxes are generally based on a percentage of annual gross sales and vary by the type of establishment. Most of the municipalities utilize a minimum base fee of $50 for businesses that generate minimal gross receipts. After the base fee, there are sliding scales for each type of establishment (i.e., retail, wholesale, etc.). At present, the maximum scheduled rate for any establishment in Ascension Parish is .39% (gross receipts X .0039) which applies to commission brokerage firms. The current minimum applicable rate in the Parish is .02% (gross receipts X .0002) which is applicable to lending institutions. Manufacturers in Ascension Parish are exempt from BPOL taxes.

Assessment and Reassessment

Commercial property is allowed to reach a base value of 20% of orignial value while the floor for industrial property is 30%. The Parish is required by Louisiana law to undertake reassessment every four (4) years.

Rollback Taxes are often employed by other areas to collect a higher rate of taxes for a defined “lookback period” of several years when a change in land use occurs in which the new use results in a higher assessment rate. For example, some communities utilize rollbacks when a piece of property converts from an agricultural to a commercial or industrial use.
