Understanding Property Tax Types & Due Dates

Property taxes may follow different billing timelines depending on the type of property. The chart below provides a general overview to help you understand what to expect.

Real Property

(Land & Buildings)

  • Bills Mailed: October
  • 1st Half Due: November 30
  • 2nd Half Due: May 31

This is the most common property tax schedule for homeowners.

Mobile Homes

  • Bills Mailed: April
  • Due Dates: May & November

Mobile homes are processed later in the year, so billing occurs in spring.

Personal Property

  • Billing: Varies
  • Due Dates: May & November (in most cases)

Business-related property may follow different rules depending on classification.

How Property Taxes Work

Property taxes move through several county and state offices before bills are mailed and payments are collected. This process spans more than one calendar year, so the tax year and payment dates do not always fall in the same year.
