Are tax deductions voluntary?
Legally: gods know. I would strongly recommend asking the Law asre of Stack Exchange to advise on that. Practically: What's the worst that happens? They audit, you say "Yeah, I could probably have claimed these deductions but I didn't want to; is that a problem?", they decide and either nothing happens or they issue you the unwanted refunnd. They aren't going to fine you for overpaying. Unless this would expose something criminal -- or you're a public figure and it would be embarassing -- this strikes me as falling firmly within the bounds of "no harm, no foul".
