Small non-profit day care org has no accounting statements/records.The org is now preparing financial statements for last year for first time even though it has been in business for many years.Some fixed assets e.g. photocopier bought in 2011 has receipt but other fixed assets e.g. bldg have no receipt/record and others have an approximate yr of purchase(2006) but there is no actual receipt. How do I value the items and from what period do I start? i.e. historical cost or FMV. And do I calculate depreciation from before 2012 or not. Very uncertain how to proceed.

Has the organization ever filed an annual information return (Form 990) with the IRS? If yes, then the value of fixed asets are included. But since you stated that no accounting has ever been done I'm guessing the answer is no. Be aware that filing form 990 is required, so having not filed one previously may raise some issues with the IRS, but nothing you can do about that now except to start following the correct procedures. I would suggest that for this first filing use FMV as best you can, and start booking depreciation going forward.
