• Submit your 2022 county tax roll to DOR no later than March 15, 2023

2023 Assessment​ and Tax Roll XML Schema

• ​XML file/schema reminders
• Parcel numbers
• Provide formatted parcels numbers with punctuation (ex: "." and "-")
• See the DOR current parcel number formats for each county
• Use consistent parcel number formats to enable DOR's use of the XML rolls (ex: processing of Real Estate Transfer Returns, chargebacks, sharing of omitted taxes, Tax Incremental District (TID) processing)
• Tax Incremental District (TID) parcels
• Identify TID parcels within the XML
• "TypeTID" – see row 143 of the Excel schema documentation
• "TIDCode" – see row 144 of the Excel schema documentation​
  
• See the active TID report for a list of each active TID, the type and the code
• Parcels without a situs address
  • Schema has a specific field called NoPhysicalAddress and allows you to either:
    1. ​Select the NoPhysicalAddress option, or
    2. Provide a standard street, city, state, zip
  • ​Enter "unknown" if your system does not support either option
• ​One parcel with multiple addresses (ex: apartment building)
• Provide each street address for the parcel
• Do not combine as a range into one entry
• See the sample file "Re3030241.XML" in the "SampleReturns" folder within the zip file
• ​Filing process
  
• Submit one real estate XML and one personal property XML for each municipality
• Name each XML with its corresponding DOR Co-muni code – to improve the XML names and quickly identify which file belongs to a specific municipality
• Submit one real estate XML and one personal property XML for each municipality – to make the XML easier to locate when working together to troubleshoot issues
• Upload the county – send a zip file with all municipality XML included​
  • Send a single zipped file for each real estate XML and each personal property XML
    
  • Make sure the zipped file only contains xml files
    
    
  • ​Do not include internal folders in your zip file​
    
• ​Send DOR your public (redacted) data to maintain consistency with providing any data
  

Filing Assistance Updates

• Can submit real estate XML with one parcel (ex: counties with a split municipality and the XML has one real estate parcel in the XML)
• Acknowledgement emails now contain parcel numbers when an XML does not meet the schema requirements
• See our filing assistance document available our website​
