I just did my 2014 taxes last night through Tax Act Online and I claimed an expense of $2,000 for improved insulation and $2,500 for replaced doors and windows on my house. I think those estimated figures are quite conservative because I probably spent more and did all the work myself so no labor costs (I am quite proficient at construction and do it as a useful hobby). Tax Act Online came up with a $500 energy credit based on those expenditures.
The problem is, I don't have any receipts so I wonder what can happen if I get audited. If so, I'd be more than happy to host an auditor to my home and show them the items installed, which all look so brand new. I will be happy to take them to the attic and show them the back paper of the fiberglass insulation I put in. However, there is no paperwork associated (purchase receipts or product documentation) because I try to minimize my record keeping (laziness/minimalism).
Considering that the amount is not that much, what are the chances I get audited and what should I do in case they demand receipts?
