The MacGregors can claim a Residential Clean Energy Credit of $7,200 for installing solar panels costing $24,000. After claiming the credit, the adjusted basis in their home becomes $507,200, as $7,200 is subtracted from the original basis of $500,000.
The Residential Clean Energy Credit allows the MacGregors to claim 30% of the cost of solar panels.
In this case, the credit is calculated as 30% of $24,000, resulting in a credit of $7,200. Therefore, option a is correct.
To find the adjusted basis, the credit is subtracted from the original basis. The adjusted basis is the original basis minus the credit.
In this scenario, the adjusted basis is $500,000 (original basis) minus $7,200 (credit), resulting in $492,800.
Therefore, option a accurately represents the situation where the credit is $7,200, and the adjusted basis in their home is $507,200 after claiming the Residential Clean Energy Credit.
