Your annual charge is set by Commonwealth and City law and calculated by a formula that applies to all taxable properties, without regard to abatements, homestead exemptions and other exemptions provided by the City of Philadelphia. The following explains the CCD methodology to calculate the assessed charges for commercial and residential properties.
Practically, we calculated the adjustments as follows:
$  % of Total  
Aggregate Commercial Assessments  $10,647,801,144  89.97% 
Aggregate Residential Assessments  $1,186,704,650  10.03% 
Total  All Assessments  $11,834,505,794  100.00% 
Original  Increase/(Decrease) to Original  Revised Assessment Total 
% of Total as Revised  
Aggregate Commercial Assessments  $10,647,801,144  $594,979,360  $11,242,780,504  95.00% 
Aggregate Residential Assessments  $1,186,704,650  ($594,979,360)  $591,725,290  5.00% 
Total  $11,834,505,794  $0  $11,834,505,794  100.00% 
To determine the total assessed charge used, pursuant to the adjustments above, we have provided an example calculation as follows:
For a commercial property with an assessed value of $100,000,000: We take the certified assessed value provided by the OPA (in this example $100,000,000) and divided it by the Aggregate of the Commercial Assessments ($10,647,801,144) and multiplied this by the adjustment amount ($594,979,360). The result is $5,587,814.35. The calculation is as follows:
$100,000,000÷$10,647,801,144×$594,979,360 = $5,587,814.35
Assessment 
$100,000,000.00 

Adjustment 
$5,587,814.35 

Total  $105,587,814.35 
Based on this Assessment, CCD’s 2017 bill would be calculated as follows:
The assessed value of the property (as revised pursuant to HB1644) ($105,587,814.35), divided by the total assessed value of the CCD ($11,834,505,794) – equals a proportion that is then multiplied by our billing amount ($18,811,780). The result is the 2017 Charge ($167,839.26). The calculation is as follows:
$105,587,814.35÷$11,834,505,794×$18,811,760= $167,839.26
For a residential property the calculation is similar; however, there would be a reduction in the assessed value. Therefore, assuming a residential property with an assessed value of $500,000, the calculation is as follows:
We take the certified assessed value provided by the OPA (in this example $500,000) and divided it by the Aggregate of the Residential Assessments ($1,186,704,650) and multiplied this by the adjustment amount ($594,979,360). The result is a $250,685.53 reduction. The calculation is as follows:
$500,000 ÷$1,186,704,650 × ($594,979,360) = ($250,685.53)
Assessment 
$500,000.00 

Adjustment 
($250,685.53) 

Total  $249,314.47 
Based on this Assessment, CCD’s 2017 bill would be calculated as follows:
The assessed value of the property (as revised pursuant to HB1644) ($249,314.47), divided by the total assessed value of the CCD ($11,834,505,794) – equals a proportion that is then multiplied by our billing amount ($18,811,780). The result is the 2017 charge ($396.30). The calculation is as follows:
$249,314.47÷$11,834,505,794×$18,811,780= $396.30
Based on its responsibility to set values for all properties, the OPA calculated a market value for your property which was the basis for the assessment that we used to calculate your bill. If you have further questions as to how the OPA arrived at your assessment, please contact them directly at 215.686.4334.
Your charge is due no later than March 31, 2017. After this date, we may charge interest and penalties on the outstanding balance until your charge is paid. Charges to condominiums within the CCD are payable to the Condominium Association.
