#### Formula
Recommended Retention Period = MAX(Regulatory Minimum, Business Need) + Litigation Hold Buffer + Sensitive Data Adder
- Regulatory Minimum — the legally mandated minimum retention period for the selected data type and jurisdiction (see matrix below).
- Business Need — the number of years the organisation operationally requires the data.
- MAX() — the longer of the two values above forms the base; you must never retain less than the legal minimum, but may retain longer for legitimate business purposes.
- Litigation Hold Buffer — 0 years (no risk), +2 years (possible dispute), or +5 years (active litigation) to protect against spoliation claims.
- Sensitive Data Adder — +2 years when the dataset contains special-category or sensitive personal data, reflecting heightened regulatory scrutiny and potential for extended claims.
Example: Financial records under GDPR with 3-year business need, possible litigation, no sensitive data: MAX(7, 3) + 2 + 0 = 9 years
#### Assumptions & References
- GDPR Art. 5(1)(e) — storage limitation principle; personal data must not be kept longer than necessary. Financial/HR records typically 6–7 years under EU member-state tax law.
- HIPAA 45 CFR §164.530(j) — covered entities must retain policies and documentation for 6 years from creation or last effective date.
- SOX Section 802 (18 U.S.C. §1519) — audit workpapers and related records: 7 years minimum.
- PCI-DSS Requirement 10.7 — audit log history retained for at least 12 months, with 3 months immediately available.
- CCPA / CPRA — no explicit retention periods mandated, but data minimisation principles apply; 2–4 years reflects common practice.
- UK Companies Act 2006 s.386–389 — accounting records: 3 years (private) or 6 years (public companies).
- PIPEDA / Canadian Privacy Act — personal information used to make a decision about an individual must be retained long enough to allow the individual to access it (typically 1–7 years depending on sector).
- Australian Privacy Act 1988 (APPs) — no universal minimum, but tax records 5 years, employment records 7 years under Fair Work Act 2009.
- Litigation hold buffers are based on typical statutes of limitations: 2–6 years for contract claims in most common-law jurisdictions.
- Sensitive data adder reflects GDPR Art. 9, HIPAA PHI rules, and the higher risk of regulatory investigation and individual claims associated with special-category data.
- Retention periods are measured from the end of the relationship or last transaction, not from data creation, unless otherwise specified by the regulation.
