Sections 45L and 179D Extended Retroactively for 2017 Projects

February 9, 2020


Early morning February, 9th the Bipartisan Budget Act was Passed providing a One-year retroactive active extension of §179D and §45L energy tax incentive provisions.

This will allow projects placed in service in 2017 to be certified for qualifying energy tax incentives. Though the original expectation was that a 2-year extension would be passed, members of the House Ways and Means committee were reluctant to pass a longer-term bill and are planning on holding hearings later this year to examine which extenders could be removed from a future longer-term package.

The retroactive passage of 179D and 45L together with the tax reform package passed in December of 2017, provide great opportunity to maximize the value of the incentives for your 2017 Tax filing. We are ready to serve you and get your projects started immediately, and we recommend getting any opportunities reviewed and started as soon a possible.
