At the moment of filing.
Just one small example if you are a company paying employer 401k contributions for tax year 2024, you have up until filing in 2025 to decide to make those contributions. This can be as late as October 15th 2025 if you file a legally allowed extension.
The March deadline mentioned probably falls in line with the normal April 15th deadline.
