Dear Solar Energy Credit,
Because I have not heard from you, I am thinking whether your question is how your credit can be taken from the Form 1065 to K-1, then, to your personal tax return of Form 1040. My basic advice is find a professional to do this. All credits have a lot of limitations. Since this is a partnership, the flow through effect is different on any and every partners. The Tax Master of the partnership needs to think through and talk through with everyone.
If you have five buildings, this is a relatively large business. If this is the first year in the business, to take on a solar penalty construction may or may not be the best investment for the first year. You need a professional to discuss with. There is another way to deal with these for you to discuss with your partners and your attorney and your accountant is to form a management company to manage this property for you all. Of course, this management company will have its own insurance, too.
Well, when you have a business of this size, the least worry should be how do I take a business credit on my 1040. All the alarms in my system come up when there are so many other issues involved.
Well, but I still want to address to your basic question. If that is your question. Where you will end up on the Form 1040 is Schedule E for Section 179 deduction. See Form 1065, sub form 8825 for rental income and expenses for partnership. https://www.irs.gov/pub/irs-pdf/f8825.pdf.
The form K-1 instruction for flowing through business credit to partners on K-1 is a good read, too. https://www.irs.gov/pub/irs-pdf/i1065sk1.pdf
Form 3468 of the Form 1040 is a good starting place to read and understand. https://www.irs.gov/pub/irs-pdf/i3468.pdf
The whole process on how the business credit flow through individual tax return is a big and significant one.
Go with these readings to start with. Feel free to follow up with me for more questions.
