Major League Soccer's Secondary Transfer Window officially begins today and runs through Thursday, Aug. 5
- Primary Transfer Window: Wednesday, March 10 – Tuesday, June 1, 2021
- Secondary Transfer Window: Wednesday, July 7 – Thursday, Aug. 5, 2021
The two transfer windows above are the periods in which MLS teams can officially register any new players who were previously under contract with clubs based outside MLS and for which an International Transfer Certificate (ITC) is required.
While deals may be agreed upon outside these windows, the transfer and receipt of an ITC are required in order to officially add a player to a roster, thus allowing him to be eligible for official competitions.
All in-season trades between MLS clubs must take place within these transfer windows.
