Background for this topic.
Tax is a compulsory payment to a government, calculated under rules that may apply to individuals, businesses, property, transactions, or income. Tax administration depends on records such as identity details, bank-account information, income data, payroll records, and business financial information. Tax agencies, employers, financial institutions, and tax professionals may exchange or store this data through filing portals, application interfaces, email, and document-management systems.

Stolen credentials or altered taxpayer records can support fraudulent filings, redirected refunds, or unauthorized access to sensitive financial information; phishing and compromise of a preparer or employer can expose many records at once. Appropriate controls include strong authentication, least-privilege access, encryption, secure data exchange, tamper-evident audit logs, and retention limits consistent with privacy and legal obligations. Security teams should also monitor filing and account changes, verify unusual requests through trusted channels, and maintain procedures for investigating suspected fraud or unauthorized disclosure.
