LEDES Ebilling Format Changes

I have been leading the Tax Accommodation Subcommittee for the LEDES Oversight Committee for the last year, spearheading changes to the global ebilling formats for two projects:
Project 1: Accommodating a greater number of cursor columns to the right of the decimal separator for the tax rate only. These proposed changes impact LEDES 98BI and XML Ebilling 2.0 and 2.1.
Project 2: New functionality to accommodate Tiered Taxes. The changes required are extensive and result in the creation of LEDES XML Ebilling 2.2. The proposed solution adds 2 new segments and 13 data elements to the file and significantly changes the invoice math statement.
You can access the proposed changes and feedback survey through https://ledes.org/proposed-standards-requiring-public-comment/, which page includes a link for providing public feedback on the proposed standards. The public comment period will remain open until 8 September, 2019.
