Last month, U.S. Sen. Cory Gardner introduced legislation to create tax deductible savings accounts for small businesses.

“Having grown up in a family-owned business, I’ve seen firsthand how difficult it can be to run a small business, make payroll, build capital, and comply with a complex regulatory system,” he said in a statement.

Gardner and U.S. Sen. Gary Peters, D-Mich., pointed to statistics from the U.S. Small Business Administration showing that small businesses — officially, those with fewer than 500 employees — encapsulate 47.5% of private sector workers. As of 2015, only 20% of those businesses had paid employees.

A 2017 version of the bill introduced in the House of Representatives denoted that small business savings accounts would be treated identically to individual retirement plans, in which there could be a maximum annual contribution of $10,000, but disbursements would generally not count as gross income.

A 2015 report from the SBA noted that 36.8% of responding businesses described access to capital as the top impediment to their growth. Other barriers mentioned were the prevalence of student debt, which prevented people from becoming entrepreneurs due to financial obligations, as well as a need for greater government spending on research and development.

More recently, the NFIB Research Foundation found that the cost of health insurance was a “critical issue” for more than half of small business respondents.
