All low and no cost measures must be implemented before the end of the performance period to earn this credit. If you’re running out of time, consider extending the length of the performance period for this credit, and for other credits as necessary, so that all prerequisites and credits end within the same 30-day window. By strategically selecting some credits to have a longer performance period, you may be able to avoid having to collect documentation for all data-intensive credits while still meeting the 30-day rule.
