Most businesses today collect far more information than they actually need and keep it for much longer than they should. In the past, this was just seen as a minor storage problem.
Today, however, keeping too much data for an indefinite period has turned into a serious legal liability. Privacy laws have expanded across the United States. Your storage habits are now a central part of your legal compliance strategy.
Why Keeping Too Much Data Can Create Legal Risks
From a legal standpoint, any data you keep is data that can be stolen in a breach, taken by a court subpoena, or inspected during a government investigation. If you keep information longer than you have a business or legal reason for, you are creating a massive risk.
Most modern U.S. privacy laws now follow a simple rule:
- only collect what you need,
- keep it only as long as necessary,
- and delete it immediately once its purpose is served.
According to IBM’s 2023 report, companies that kept excessive data saw breach costs that were 16% higher than those with strict data rules.
This is because having more data makes a hack much bigger and attracts more attention from government regulators who look for excessive collection.
How Federal Laws Set Minimum Data Retention Periods
Federal laws usually set minimum retention periods. These are the shortest amounts of time you are legally allowed to keep specific records.
Businesses Must Keep Tax And Employee Records
For tax records, the IRS generally requires businesses to keep files for at least 3 years. Although this can jump to 7 years for certain types of debt or losses.
For employment records, the Equal Employment Opportunity Commission (EEOC) requires you to keep personnel files for 1 year. Workplace injury records under OSHA must be kept for 5 years following the year they cover.
Health And Financial Records Must Be Retained
In the healthcare world, HIPAA requires specific documents like policies and training records to be kept for at least 6 years. Finally, the financial industry, regulated by the SEC and FINRA, must keep records for between 3 and 6 years. It also depends on the specific type of document and its relevance to consumer transactions.
How State Privacy Laws Limit How Long Data Can Be Kept
While federal laws set the floor, state privacy laws often set the ceiling. These laws focus on maximum retention periods. They state that businesses must delete personal info once the reason for collecting it is over.
The California CPRA explicitly requires businesses to:
- Disclose in their privacy notice how long each category of personal information is retained
- Retain personal information only as long as reasonably necessary for the disclosed purpose
- Delete personal information that exceeds the disclosed or necessary retention period
How Businesses Balance Federal Retention Rules With State Privacy Limits
This creates a difficult balancing act for many companies. You must keep some records for years to satisfy federal rules, but you must delete personal data to follow state privacy laws.
Managing this requires a system that can tell the difference between a regulated business record and basic customer data. You need to build schedules that satisfy the federal minimum requirements. At the same time, you should apply strict deletion dates to personal information that is no longer needed
Data retention is now a mix of legal duty and risk management. You cannot store everything forever. You need a documented, technically enforced program that follows federal minimums and state maximums. This protects your business from both lawsuits and expensive data breaches. It is the best way to manage your current legal exposure.
If your business needs help reviewing its data retention practices, consult with an experienced legal professional.
