How Property Tax Works

Tangipahoa Parish, Louisiana operates on an ad valorem property tax system that funds essential local services including parish government operations, public schools, fire protection, drainage districts, and other municipal services. Property taxes in Louisiana are assessed at fair market value and collected by the parish tax collector, with revenues distributed to various taxing authorities based on established millage rates.

The effective property tax rate in Tangipahoa Parish typically ranges from approximately 0.8% to 1.2% of assessed value, though this varies significantly by location within the parish due to different combinations of special taxing districts. Property owners may be subject to parish-wide levies, school district taxes, municipal taxes (if within city limits), fire district assessments, and various other special district levies depending on their property's location. Rates are set annually and can change based on budgetary needs and voter-approved bond issues.

Section 4

Supplemental Tax Bills

Supplemental taxes in Tangipahoa Parish are additional assessments that occur when there are changes to property ownership, new construction, or improvements made to existing properties outside of the regular assessment cycle. These taxes are calculated based on the pro-rated difference between the old and new assessed values for the remaining portion of the tax year.

Common triggers include property sales that result in reassessment at current market value, completion of new construction or major renovations, and addition of structures like pools, garages, or home additions. The supplemental tax is calculated by taking the difference in assessed value, applying the current millage rate, and pro-rating for the months remaining in the tax year. For example, if a $200,000 home improvement is completed in July and increases assessed value by $200,000, with a total millage rate of 100 mills, the supplemental tax would be approximately $1,000 ($200,000 × 0.10 × 6/12 months).

Escrow & Property Taxes

Most mortgage lenders in Tangipahoa Parish require property tax escrow accounts for borrowers with less than 20% down payment, though some lenders may require escrow regardless of down payment amount. The lender collects monthly payments equal to 1/12 of the estimated annual property tax bill and maintains these funds in a separate escrow account to pay taxes when due.

Property taxes in Tangipahoa Parish are typically paid in three installments: the first installment due September 1st, second installment due December 1st, and the final installment due March 1st of the following year. Lenders usually pay each installment when due using escrowed funds. Property owners should verify their annual escrow statement for accuracy and contact their lender immediately if there are discrepancies, as incorrect escrow calculations can result in shortages or overpayments. The lender is required to provide an annual escrow analysis showing projected payments and any surplus or shortage adjustments.
