I'm with you now. I think you might be talking about the 2% rule. I know you cannot claim health care or work expenses, ect. unless they exceed 2% of your adjusted gross income. Charitable deductions are not held to that standard, same with your mortgage interest, taxes on personal property (ie car tabs) and property tax.
Do you do your own taxes? There are number of at home software packages that are great for helping you thru all sorts of tricky questions.
I am a nerd. I know. I worked for a year in a CPA's office. I have really bounced around since college. I was Creative Memories for 2 yrs. Then I was at Fingerhut for 4 yrs, had DD, then went to Wells Fargo for 2, left to work at the garden center, went back in the fall to work at CPA's office, left to work at garden center, then back to work at Select Comfort. I have more useless information stored in my head than I'd rather admit.
