If everyone was a volunteer, some may know tax rules better than others. It may not have been a slight to you personally. It may even have been a learning curve for the volunteer. Someone else may have recently taken charge and insisted everyone be given a tax receipt.
We always just take the standard deduction. Itemizing and then keeping track of receipts and then have a senior moment (which occurs more often these days) and forgetting where we put them. Also, we have accumulated so much in the years that we have lived here, that I'm thinking of throwing out a lot of old receipts/paperwork. I wonder if it's okay to throw stuff out that is 10 plus years? Just how far back does the IRS go when they do an audit?
