Insulation Tax Credit question.......

Now this is going to sound bad.....but I am doing my first job where the homeowner asked about and is requesting all information needed for filing for tax credit.

I put a roof on this house and a long story short it only has about 3" of blown in fiberglass insulation in the attic.....I gave them a price to install another 12" or so. They can get 30% of the cost of insulation materials only on tax credit.

To get the tax credit the customer needs Manufacturer's Certification Statement..which I have. They also need a "sales receipt"...and this is where I have questions.

Am I suppose to provide them with an actual receipt from where I buy the materials, my cost.....or is the invoice/receipt I give them from my company ok? My invoices seperate materials and labor...so the IRS and customer would know what they paid me in labor and what was materials. This would just be so much easier then trying to get an actual receipt from my material supplier....since they just invoice me once a month for all jobs in that month. You guys follow me or did I confuse the hell out of you?

Thanks! Randy

You need to provide them with the invoice for the entire job. Labor, materials everything. This is the amount it cost to have the services completed and this is the amount they can recieve a percentage of credit for. I have done this many times over the past couple of years and this is the proper way to do it.
