For the State Program, yes. As long as the project is still ongoing it may be Phased at any time before the project has been completed. A Phasing Plan must be submitted for review and approval as soon as possible.
For the Federal Program, no. In order to use the 60-month measuring period for a Phased project, the taxpayer must choose to Phase the project from the beginning. This means that a Phasing Plan, showing what work will be completed during each phase of the project, must be submitted before work begins. For some projects, it may be a good idea to submit a Phasing Plan at the start of the project, even if there is a possibility the project can be completed within two years. This will “hold open” the 60-month time period but does not obligate the taxpayer to take that long to complete the project.
See the “Project Phasing” document for more information.
