• On July 14, 2022, Emerling-Gase Motorsports announced that they would expand to two full-time cars, with the No. 53, previously a part-time car, running full-time in 2023. One car would have one full-time driver with multiple drivers sharing the other car. On February 2, 2023, the team announced that the No. 53 car would be driven by team co-owners Joey Gase and Patrick Emerling (as well as previously announced part-time drivers Brad Perez and C. J. McLaughlin), making the No. 35 car the car that will have one full-time driver.
• On August 25, 2022, Front Row Motorsports announced that Zane Smith, who drives for the team full-time in the Truck Series, would run part-time for a Ford team in the Xfinity Series with entries being fielded in a collaboration with them (instead of FRM starting their own Xfinity Series team).
• On September 20, 2022, JD Motorsports announced that they would expand to three full-time Xfinity Series cars in 2023. The team downsized from four full-time cars to two in 2022.

• On November 5, 2022, Mike Harmon Racing announced that Gary Keller would join the team as a co-owner after having been a co-owner of JD Motorsports from 2012 to 2022.

On December 19, Brandon Kauffman, the team's PR & Marketing Assistant, teased on the NASCAR Reddit page that the team would field the No. 74 car again in 2023. In 2022, MHR only fielded that car in the season-opener at Daytona when it had run full-time for several years prior. On January 13, 2023, the team announced that they would be renaming to CHK Racing after the addition of another co-owner, Michael Clayton Sr, as well as to reflect Keller's new co-ownership of the team.

• On December 8, 2022, Joe Gibbs Racing announced that their No. 54 car would be renumbered to the No. 20 in 2023. JGR did not use that number in 2022 after downsizing from four full-time Xfinity Series cars to three and the No. 20 car was the car that closed down.
• On December 8, 2022, Sam Hunt Racing announced that they would expand to two full-time cars in 2023, with their No. 24 car now being fielded full-time after having been fielded part-time in 2021 and 2022.

• On March 3, 2023, Preston Pardus announced that he would return to driving for his own team in the Xfinity Series, which he last did in 2019. That year, the team used the No. 43, which is now taken by Alpha Prime Racing, so the team switched to the No. 50, a number that Pardus' father Dan used in the Cup Series in 1999 driving for Midwest Transit Racing. The first Xfinity Series race Preston and his team ran in 2023 was Circuit of the Americas.
• On March 7, 2023, Cup and Truck Series team Spire Motorsports announced that they would expand into the Xfinity Series in 2023, fielding the No. 77 car part-time for Carson Hocevar, who drives full-time in the Truck Series for Niece Motorsports.

Manufacturers

• On December 12, 2022, AM Racing announced it would switch from Chevrolet to Ford in 2023, with a technical alliance with Stewart-Haas Racing.

Sponsorship

• On November 1, 2022, JR Motorsports announced that Bass Pro Shops, which previously sponsored Noah Gragson's No. 9 car for the team, would switch their sponsorship to Josh Berry's No. 8 car in 2023 and would sponsor him in 11 races.

• On December 7, 2022, Jesse Iwuji Motorsports filed a lawsuit against their primary sponsor of the No. 34 car in 2022, Equity Prime Mortgage, for lack of payments to the team. This would be followed by EPM filing a counter-lawsuit against JIM for breach of contract. As a result of the loss of EPM as a sponsor, the team had to reduce their No. 34 car to a part-time schedule in 2023 and cancel plans to expand to a second car.
