Vice President Kamala Harris on Wednesday will unveil a new proposal to provide small businesses with a $50,000 tax deduction for startup expenses, ten times the current $5,000 allowable deduction, according to a Harris campaign official who was granted anonymity to share details of a proposal that is not yet public. Harris will roll out the new plan at a presidential campaign event in New Hampshire on Wednesday, part of her broader kick-off of the post-Labor Day two-month sprint to Election Day. Under the proposal, new small businesses could spread the deduction out over several years, or delay claiming the $50,000 tax deduction until the company turned a profit. The Internal Revenue Service
