Tax Credit Eligibility FAQ

Any government loan considered "subsidized energy financing"- and most should be - is used to reduce the "basis" on which the credit is calculated before 2009. For the commercial credit, if the system was partly constructed before 2009, then there will be reduction in basis for the share of the cost incurred before 2009 that was financed with such a loan. For the residential credit, there is no reduction on account of such a loan for any system on which installation was completed after 2008. It does not matter if work started in 2008.
