Peter - I volunteer in the AARP Foundation Tax-Aide program and tell my clients to keep a simple notebook log sheet for each category writing in the date, description, amount, and mileage if applicable for qualified medical expenses. I tell them to total each category before coming in and be sure to have all the supporting data in the event of an IRS audit.
I myself use an Excel spreadsheet for each category of itemized deductions and it totals everything for me. I just have to remember the make all the entries. Tom D.
