Federal Tax Credits in effect through 2021

EDIT: 12/2015

In December 2015, the Consolidated Appropriations Act extended the 30% credit for residential solar to the end of 2019.  It then steps down over two years and expires completely at the end of 2021.

  • 30% for systems placed in service by 12/31/2019
  • 26% for systems placed in service after 12/31/2019 and before 01/01/2021
  • 22% for systems placed in service after 12/31/2020 and before 01/01/2022
  • There is no maximum credit for systems placed in service after 2008.
  • Systems must be placed in service on or after January 1, 2006, and on or before December 31, 2021.
  • The home served by the system does not have to be the taxpayer’s principal residence.

RVs and the Solar Federal Tax Credit

** Every individual's tax situation is different. Please consult a tax professional to make sure your situation is applicable. The following is for educational purposes only and does not constitute legal advice.

The law permitting the federal tax credit is 26 USC Section 25D. It says:

(2) Qualified solar electric property expenditure
The term “qualified solar electric property expenditure” means an expenditure for property which uses solar energy to generate electricity for use in a dwelling unit located in the United States and used as a residence by the taxpayer.

And the IRS definition of "dwelling unit":

A dwelling unit includes a house, apartment, condominium, mobile home, boat, vacation home, or similar property. It also includes all structures or other property belonging to the dwelling unit. A dwelling unit has basic living accommodations, such as sleeping space, a toilet, and cooking facilities.

Finally, is an RV considered a mobile home? For that we look to this US Tax Court memo 2014-160 on Jackon & Jackson v. Commissioner, page 14:

This Court has previously held that a motor home qualifies as a dwelling unit within the meaning of section 280A(f)(1)(A). See, e.g., Haberkorn v. Commissioner, 75 T.C. 259, 260 (1980); Dunford v. Commissioner, T.C. Memo. 2013-189, at *23-*24; Perry v. Commissioner, T.C. Memo. 1996-194, slip op. at 14.

Although we use the more modern term throughout this opinion, an RV and a motor home are one and the same thing. Petitioners and counsel used the two terms interchangeably at trial. Accordingly, petitioners’ RV is a dwelling unit for purposes of section 280A.

Solar Tax Credit History

The Emergency Economic Stabilization Act of 2008, which was signed into law on October 1, 2008, was a boon to the renewable energy market. Not only was the 30% commercial solar investment tax credit extended through 2016, but the same tax credit was also extended to residential installations.

Under this legislation the previous $2,000 cap for residential solar installations was eliminated. As of January 1, 2009, the purchase of a residential solar electric system makes you eligible for a tax credit equal to 30% of the cost of your solar system, including installation. See full information on how you may use the tax credit.
