Impact Analysis

Personal Impact

The bill does not directly target small business owners, but by strengthening whistleblower protections and incentives, it could increase the number of tips about tax noncompliance. Small businesses that comply with tax laws benefit from a more level playing field, while those engaged in underreporting could face greater scrutiny.
