Any possibility of tax reform in Congress means the future becomes a bit hazy for some non-profits.

Some leaders fear the overhaul could lead to fewer charitable donations.

"There's like a ripple effect," said Salvation Army Major Karen Smullen.

"I guess we'll have to wait and see over time what happens," said Pivot Prevention and Health Services Executive Director Bill Bowman.

Charitable donations are considered tax deductible if one itemizes their deductions.  But with the proposed doubling of the standard deduction, many might choose to avoid that process. Non-profits worry that choice might convince some to stop donating.

For groups like the Salvation Army, those donations are essential.

"We can't live without them," said Smullen.

And it's no secret that tax breaks incentivize donors.

"It's gotta be like how it pans out for individual donors, whether they decide not to donate because they don't want to itemize," said Smullen.

Changes wouldn't affect all non-profits equally. Some are dependent on the government for funding.

"But if you look at the percentage of our funding, most of it is public sector funding, and most of it is state and federal funding," said Bowman.

As for the overall impact of tax reform on non-profits, nothing will be certain until the final vote is made.
