Tax - 2023 & 2024 Regulatory Events

2023 and 2024 Regulatory Events in U.S. Tax - Explore bill, regulatory changes, and agency updates from 2023 and 2024.



As industries are headed into another year of keeping up with legislative and regulatory developments ahead, Regology compiled an overview of the events that took place in the field of taxation during 2023 to demonstrate their magnitude. This overview also contains an overview of the law proposals submitted in 2024 to date.

All events were all captured on the Regology platform, highlighting the level of automation and convenience available today to identify the events that are discussed here, with 8,388 events relating to 2023. The 8,083 events from 2023 are a part of the 707,834 events that Regology tracked across the US in 2023.

Overview of Events - 2023

Regology’s dedicated tax law library consists of laws and regulations relevant to taxation and organized by type of tax. We used several of its components for this overview and they generated 8,388 alerts for the year 2023. The alerts range across the legislative and executive branches and include:

  1. Proposed law changes (Bills)
  2. Changes to compiled statutes and regulations (Regulatory Changes)

The below show the breakdown of these alerts across the various types.


Across the United States, 5,498 bills were identified that include one or more references to sections of the compiled statutes within the selection of Regology’s tax law library. A total of 1,046 bills made it into law, whereas 4,058 of them did not advance to the next house of the legislature. 316 bills have passed the initial chamber and 47 bills have passed both, leaving the remaining 31 awaiting signature. 

The below contain an overview of these metrics. For this overview, we have left out the bills that have died in 2023.

Regulatory Changes

Across the United States, 2,585 change events were recorded that amended the compiled statutes (1,298) and regulations (1,287). The figure below depicts where these changes happened across the United States.

A single regulatory change can have an impact on multiple regulatory topics. The table below shows all the regulatory topics within Regology’s tax law library used for our analysis that were impacted by legal and regulatory changes. A total of 13,836 occurred in 2023, as shown in the table below.

2024 Update - Bills

To give an insight into how much activity we have already seen in 2024, the following overviews provide an insight into the 2,000+ bills that have already been introduced this year. 

  • Overview of Bills that have not advanced to the next house of the legislature (first figure below)
  • Overview of Bills that have advanced to the next house of the legislature and beyond (second figure below)


To demonstrate the pace of legislative and regulatory change, Regology exported the 2023 metrics for some of its industry and topic-based law libraries into a digestible overview. We invite you to view any of our other industry/topic-focused publications we release over time. Our analysis provides an insight into the depth and breadth of our capabilities that are used by our customers to keep up with the constant pace of legislative and regulatory change. Complying with laws requires an agile approach that is capable of identifying and responding to changing requirements in a continuous manner.


This overview assessment of legislative and regulatory events corresponds to the events identified by the Regology platform in 2023 regarding the field of taxation. For a closer look into any of the events that this overview comprises, we note that these are all available on the Regology platform.

The metrics presented in this report were, for the most part, derived automatically from the content that is continuously updated on the Regology platform. It includes several of Regology’s AI-based regulatory intelligence technologies to identify change events within—and across—publicly available law publications relevant to taxation. 

To avoid overstating the numbers of impacted clauses, we counted the codification of changes as a single event, and we presented the numbers for the U.S. Federal Government in a manner comparable to those for the States. For example, the rule changes published in the Federal Register were omitted from our count and are picked up at the federal and state levels within the compiled regulations. 

Finally, as the connected collection of legislative and regulatory materials housed on the Regology platform continues to be further enhanced, new capabilities and metrics will soon be introduced to further build out our analyses.
