Deductions & credits

Sorry, the 30% credit is only effective for heat pumps placed in service after 1/1/23. That credit is 30% of the cost plus installation up to $2000.

For property installed in 2022, you have to use the rules in place for 2022.  That's a 10% credit with a cap of $300 and a lifetime cap of $500, so if you claimed the same credit in the past for other energy saving improvements, your credit now might be further reduced.
