Energy tax credits are still available in 2011 with changes made from 2010. If you're confused about what you can claim, let us help you.
2010 Energy Tax Credits: 30% of product cost up to $1,500.00
2011 Energy Tax Credits: 10% of product cost up to $500.00
Also note, that any energy tax credit taken in 2010 or before will count against the $500 limit you can claim in 2011. So, if you claimed $200 in energy tax credits in 2010, you are now only able to claim up to $300 in 2011.
