What are Property Tax Deferrals?

Homeowners over 65 and individuals with disabilities have an option to defer payment of taxes on their homestead at a lower rate. Property tax deferrals allow qualified homeowners to pay taxes without penalty at any time, using 8% interest per annum rather than the standard 24% penalty and interest. Deferrals cannot be applied retroactively to delinquent taxes from past tax years, only to those currently due. In other words, any tax that is delinquent before the deferral period begins, is not eligible for the 8% interest per annum.

Homeowners and those who assist or care for them are advised that the deferred status changes immediately upon the sale or change or property ownership. On the 181st day after the deferred status changes, all standard penalty and interest charges for all years are due.

When can Over-65 or Disabled Persons pay their taxes?

Only taxpayers with an Over-65 or Disabled Person Exemption may pay current Collin County Property taxes on their homestead residence in four installments without penalty or interest:

  • ¼ of the payment by Jan. 31
  • ¼ by March 31
  • ¼ by May 31
  • ¼ by July 31

If an installment is missed, the full penalty will accrue.

When will a penalty be incurred if I do not pay my Collin County Property taxes on time?
