Reassessment Update:  

  • Delaware County will be mailing on July 1st a new letter with property Reassessment values to all parcel owners.
  • Parcel owners will be able to schedule a Formal Appeal of the new Reassessment value until Sept 1st only.
  • Formal Appeals are free and will be held July to October. Residents will receive final results and values based on appeals on or about November 15.


  • Delaware County commenced the notification process for property reassessment on February 14th with weekly mailings to municipalities over a rolling 4-week period.
  • Municipalities are segmented into 1 of 4 zones with Radnor in Zone 4 and notifications scheduled for a March 6th mailing.
  • Below is a sample of the notification you will receive – it is a Notice of Tentative Assessment Change.
  • The new value assigned to your property is intended to be the Fair Market Value as of July 1, 2019.  In a letter you will receive from the county there will be specific instructions and a phone number to call if you disagree with the tentative assessment. (10 Business Days)
  • The County is providing a limited window of time to schedule an informal review to challenge the tentative assessment.
  • Final assessments are expected to be released in July and a formal hearing request would have to be made if a property owner disagrees with the final assessed value.
  • The impact on your property tax bill(s) will be effective beginning January 1, 2021.

Tax Impact:

IMPORTANT – your property tax bill in 2021 will be based upon the new millage rates as established by the respective taxing jurisdictions:

  • County
  • Township
  • School District

The purpose of the reassessment is to distribute the property tax burden among properties based on current fair market value.  The reassessment cannot legally be used by any of the above taxing jurisdictions to generate more tax revenue.  Do not apply the current tax rate to your new assessment as the result will be inaccurate.  The new millage rate will be determined independently by each of the taxing jurisdictions for the 2021 year.


  • At January 1, 2020 the assessed value of all taxable residential and commercial property in Radnor Township was $3,224,795,616 and the millage rate for the Township is 4.4082.  The Radnor Township cumulative property taxes to be collected this year to help fund Township services is calculated as follows: 

( $3,224,795,616 / 1000 ) x 4.4082 = $14,215,544

  • Let’s assume, that after reassessment, the combined values of all taxable residential and commercial property in Radnor Township increased by 100% ($3,224,795,616 x 2) or a value of $6,449,591,232.

Real estate taxes for the Township in 2021 would NOT BE: 

( $6,449,591,232 / 1000 ) x 4.4082 = $28,431,088

Rather, the Township, and all taxing jurisdictions, must by law, adjust the millage rate to reflect a revenue neutral result.  In the example, since it was assumed that property values doubled (100% increase), then the millage rate must be reduced in half.

Real estate taxes billed in 2021 for the Township would be as follows: 

( $6,449,591,232 / 1000 ) x 2.2041 (4.4082 / 2) = $ 14,215,544

PLEASE NOTE – while the Township millage is adjusted based on the overall average increase in assessed values, each individual’s newly assessed property values may be above or below the average.  As such, those property owners may see an increase or decrease in taxes based on their specific assessment.

As a reminder, the County wide property reassessment project is a Delaware County project.  Please see their website for further information at:

  • There is a link titled “Tax Reassessment” on the homepage of the above site which will direct you to the website below which provides detailed information on the reassessment project.
  • Should you wish to schedule an informal review, there is a limited, 10 day window beginning with the date on the letter. Please call Tyler Technologies (888-773-7056) between 8:30am - 4:30pm once your letter has been received. Please do not call before as Tyler Technologies will not be able to address these calls prior to letter distribution.
