Re: itemized sales tax deduction
You are allowed to take a standard sales tax deduction, and add to that any big ticket items. A sales receipt showing the sales tax of the big ticket items should suffice. Keep it with your records, just like a charitable donation slip or business expense receipts. The forms, when I last looked at them, just had a 'total' box. But you will need to explain it with records if asked to do so.
Be fearful when others are greedy, and greedy when others are fearful. Just another form of "buy low, sell high" for those who have trouble with things. This rule is not universal. Do not buy a 1973 Pinto because everyone else is afraid of it.
