Relates to a business tax credit for purchase of data breach insurance

S 4427 creates a 25% tax credit for small businesses (those with fewer than 101 employees) that purchase qualified data breach insurance. This insurance must cover expenses related to data theft, loss, or unauthorized access, and businesses must comply with cybersecurity standards like the NIST framework or state-approved equivalents. The bill requires insurance premiums to be separately itemized in contracts and limits the credit to premiums paid in ordinary business operations. It applies to taxable years beginning after the law takes effect and expires after five years.
