As if that weren’t enough, violent tragedies in Las Vegas and Sutherland Springs rocked the nation.

Of highest concern is doubling the standard deduction limit currently in place for taxpayers. According to IRS data, this would remove the tax incentive for an estimated $95 billion of annual charitable giving and reduce the number of itemizers from one-third of Americans to about five percent. This could reduce charitable giving by as much as$20 billion.
