In 2020 the LEDES Oversight Committee ratified the LEDES XML Ebilling Ver. 2.2 format as an update to LEDES XML Ebilling 2.1. In addition to incorporating other changes, XML 2.2 adds functionality to support Tiered Taxes, as has been seen with a Withholding Tax in Japan.
The 2.2.1 versions included a new schema for how rates are entered, allowing for the submission of rates in the timekeepers’ home currency when an invoice is presented in a different currency. With this new schema, law firms only need to receive rate approval in the timekeepers’ home currency instead of for each various permutation of this value when currency conversion rates change. Law Firms should confirm with their client vendor that this update has been released on the Client’s platform before using this new Rate schema. his newest version, ratified in March 2023, includes minor revisions as well as a rethinking of how rates are submitted. Law Firms should confirm with their client vendor that this update has been released on the Client’s platform before using the new Rate schema.
The format documentation has been updated 3 times since the original release. This newest version, authorized by the Board in April 2026, corrects a math error in the 2.21x versions that had Clients Funds applied twice in the invoice total.
