Retention period requirements for preservation of records
Note: Highlighted words or sections indicate new or updated material from the last version of this guidance.
Below is a summary of the record-retention requirements for sales and use tax, federal and state income tax, and federal and state employment tax.
You’ve recently noticed that old files have taken up what little filing space you have left. Can you throw some of them away?
Record-keeping policies must be guided by the rule of reason and not by the statutes of limitations alone. Moreover, any external investigation by a law enforcement agency requires an employer to “freeze” all records that may in any way be associated with the investigation. The following are general guidelines that refer to the minimum record preservation times required by law.
Sales and Use Tax Records
Minimum Retention Period: Four Years
State, County, and City
If you hold a California seller’s permit, you are required to maintain business records to verify that you have properly paid tax. All records pertaining to transactions involving sales or use tax liability must be preserved for a period of no less than four years, unless you have written authorization to destroy them sooner. In addition, if you are being audited, all records for the period being audited until the audit is completed, or the case is resolved, should be retained.
Be mindful that if you have a point-of-sale system that overwrites data after a period of time less than four years, you should transfer, maintain, and have available, all data that would have been overwritten or otherwise removed from the system.
You want to keep all records required to determine your correct sales and use tax liability. These records usually include:
- the normal books of account that show your business income and expenses;
- all bills, receipts, invoices, job orders, purchase orders, contracts, cash register tapes or other documents of original entry supporting the entries in the books of account;
- all schedules or working papers used in preparation of your sales and use tax returns.
The documents you keep should be able to show the following:
- gross receipts from all business income, whether considered taxable or nontaxable, including sales (alcoholic beverages, soft drinks, food, etc.), leases, service charges and labor income;
- all deductions claimed in filing your sales and use tax returns with supporting documentation;
- total purchase price, including receipts, for all items you purchase for resale, lease or your own use.
NOTE: Failure to maintain accurate records may be considered evidence of negligence or intent to evade the tax and may result in penalties.
There may be additional requirements based on your city and county as well.
For further information regarding maintaining sales and use tax records, see Regulation 1698 in Article 18 of The Business Taxes Guide and Property Law Guide, which can be accessed through the California Department of Tax and Fee Administration website.
Income Tax Records
Minimum Retention Period: Six to Seven Years
Federal and State Employment Tax Records

Additionally, the records should indicate the total remuneration, including amounts withheld for any reason, paid to employees during this calendar year; the amount of such remuneration constituting wages subject to tax; the amount of contributions paid into each state unemployment fund; and the extent to which the employer is liable for the tax. If the total remuneration paid and the amount subject to the tax is not equal, the reason must be made a matter of record. In addition, the records must show the dates, in each calendar quarter, on which each employee performed services not in the course of the employer’s trade or business and the amount of cash remuneration paid at any time or such services performed.
- Federal Insurance Contributions Act (FICA): An employer must keep records that reflect the following information with respect to each employee: the name, address and account number of the employer; the total amount and date of each payment of remuneration and the period of services covered; daily and weekly hours; straight time and overtime hours and pay; annuity and pension payments; fringe benefits paid; tips; deductions and additions; the amount of each payment of remuneration that constitutes wages subject to tax; the amount of employee tax collected with respect to such payment, and, if collected at a time other than the time the payment was made, the date collected; if the total remuneration payment and the taxable amount of that payment are not equal, the reason; the details of each adjustment or settlement of taxes under the Act; and a copy of each statement furnished in explanation of any omission or error in a return or schedule required by regulation.

For California, payroll records should also be kept for at least four years. If you believe that you are not a subject employer or you have exempt employees, California requires you to maintain records of payments made to people who provide services to your business for at least eight years in case of an employment tax audit. Your records must provide a true and accurate account of all workers (employed, no longer employed, on a leave of absence, and independent contractors) and all payments made. Records must include the following information for each worker:
- Worker’s full name (first name, middle initial, and last name)
- Worker’s social Security number
- Date hired, rehired, or returned to work after a temporary layoff
- Last date services were performed
- Place of work

Fair Labor Standards Act and Equal Pay Act: Three Years, Two Years
Firms with sales of $500,000 or more, companies engaged in interstate commerce and public agency employees are subject to the provisions of the Fair Labor Standards Act (FLSA). Those with 15 or more employees are subject to the provisions of the California Equal Pay Act of 1963.
The FLSA requires that the following records be kept for three years from the date of the last entry:

Age Discrimination in Employment Act of 1967: Three Years
The Age Discrimination in Employment Act (ADEA) requires that employers of 20 or more workers keep for three years the following: time cards, payroll and other records for each of their employees that contain the employee’s name, address, date of birth, age, sex, occupation, rate of pay, hours worked each day and compensation earned each week, including straight-time earnings, weekly overtime earnings, deductions from or additions to wages, date of payment and the period covered by the payment.

Civil Rights Act of 1964 (Title VII), Federal Discrimination Law: One Year
Employers of 15 or more workers are subject to the provisions of the Civil Rights Act of 1964 (Title VII) and are required to “make and keep such records relevant to the determination of whether unlawful employment practices have been or are being committed.”
To comply with this general record retention requirement, any personnel or employment records, including forms submitted by applicants and other records having to do with hiring, promotion, demotion, transfer, layoff, or termination, as well as rates of pay or other terms of compensation, selection, job descriptions, retirement, pension and insurance plans, union agreements and contracts, seniority and merit system descriptions and training, should be retained.
When a person has filed a lawsuit against an employer, the employer is required to keep all relevant records regarding that individual that may either prove or disprove discrimination until the lawsuit has reached a final disposition.
For further information visit the U.S. Equal Employment Opportunity Commission (EEOC) website.
Immigration Reform and Control Act of 1986: Three Years
Under the Immigration Reform and Control Act of 1986 (IRCA), all employers are required to keep completed I-9 forms on file for every employee hired after November 6, 1986. These records must be retained for at least three years from the date of hire, or one year after termination, whichever is greater.
I-9 Forms and supporting documents should be kept in a location separate from the employee’s personnel file and be made available for USCIS inspection within three days of a request for lawful inspection. You face civil penalties for violating these record-keeping requirements, ranging from $110 to $1,100 for each infraction.

If a charge of discrimination is filed or the Equal Employment Opportunity Commission brings an action, an employer must save all personnel records related to the charge until it is resolved.
For further information visit the U.S. Equal Employment Opportunity Commission (EEOC) website.
Family and Medical Leave Act: Three Years
The Family Medical Leave Act (FMLA) and the California Family Rights Act (CFRA) contain similar provisions as to which employers are covered:
- FMLA: Private employers are covered by the FMLA if they have employed 50 or more employees within 75 miles of the workplace of the employee requesting FMLA leave for each working day during each of 20 or more calendar workweeks in the current or preceding calendar year.
- CFRA: As with the FMLA, an employer who directly employs 50 or more persons to perform services for a salary or wage is covered under the CFRA. In accordance with the FMLA, the coverage threshold is reached under the CFRA if an employer has employed 50 or more employees for each working day during each of 20 or more calendar workweeks in the current or preceding year. Also in conformity with the FMLA, the employees can be located anywhere in the U.S. or any territory or possession of the U.S. This means that an employer with only one employee in California can be a covered employer! (But no employees would be eligible for leave unless all were employed within a 75–mile radius).
Unlike the FMLA, the CFRA has no specific recordkeeping provision. However, the general recordkeeping requirements under the Fair Employment and Housing Act (FEHA) apply, including the requirement that employment records be kept for a period of at least two years (see below for FEHA recordkeeping requirements).
According to the FMLA, all employers should keep the following records for at least three years:
- name, address and occupation
- rate of pay, terms of compensation, daily and weekly hours worked per pay period and additions to and deductions from wages and total compensation paid
- dates of leave taken by eligible employees (the leave must be designated as FMLA leave)
- for FMLA leave taken for less than one day, the hours of leave taken
- copies of employee notices and documents describing employee benefits or policies and practices regarding paid and unpaid leave (copies may be kept in personnel file)
- records of premium payments for employee benefits
- records of any dispute regarding the designation of leave
- any employee handbooks and/or policies on employee leaves and benefits
- records and documents relating to medical certifications, re-certifications and medical histories of employees or their family members. Where the ADA applies, the records must be maintained in conformance with ADA confidentiality requirements.
- Such documents must be maintained as confidential medical records (i.e., kept in files separate from the employer’s ordinary personnel files).
- Exceptions: The confidential medical records (above) may be disclosed to the following persons: Supervisors and managers regarding necessary restrictions on work and necessary accommodations:
- First aid and safety personnel (e.g., where physical condition might require emergency medical treatment); and
- Government officials who are investigating compliance with FMLA or other laws on request.
- employee pay and benefits plan
- records of employee disputes.
For further information visit the U.S. Department of Labor website for FMLA and The California Department of Fair Employment and Housing website for CFRA.
Occupational Safety and Health Act: Five Years to 30 Years
The Occupational Safety and Health Act (OSHA) applies to any employer with at least 10 employees and requires an employer to keep a log of occupational deaths, injuries and illnesses (other than minor injuries requiring only first aid treatment) and a supplemental record of deaths, injuries and illnesses for at least five years. Additionally, an employer must maintain medical records and records of exposure to potentially toxic substances or harmful physical agents for each employee for at least 30 years after the employee has resigned or been terminated.
Employers in a specified low hazard retail, service, finance, insurance or real estate industry are generally exempt from maintaining OSHA injury and illness records. However, even otherwise exempt employers must maintain illness and injury records if requested to do so by OSHA or the Bureau of Labor Statistics. Moreover, workplace incidents resulting in a fatality or hospitalization of three or more employees must be reported to OSHA regardless of the size of the employer or number of persons employed.
Employers are required to maintain the following or equivalent forms:
- “Log of Work–Related Injuries and Illnesses” (OSHA Form 300);
- “Incident Report” for each recordable injury or illness (OSHA Form 301); and
- annual summary of such injuries (OSHA Form 300–A).
OSHA also requires employers to post a complete summary of all injuries and illnesses each year.
For further information visit osha.gov.
State Personnel Records: Four Years
Employers must maintain a copy of each employee’s personnel records for at least three years after termination of employment, but since wage and hour violations contain a four-year statute of limitations, the employer should retain the employee’s personnel records for at least four years after the employee leaves his employment.
Wages, Hours and Working Conditions: Four Years
Every employer shall keep accurate information with respect to each employee, including:
- full name, home address, occupation and social security number
- birth date, if under 18 years, and designation as a minor
- time records showing when the employee begins and ends each work period. Meal periods, split-shift intervals and total daily hours worked must also be recorded. Meal periods during which operations cease and authorized rest periods need not be recorded.
- total wages paid each payroll period, including value of board, lodging or other compensation actually furnished to the employee
- total hours worked in the payroll period and applicable rates of pay. This information shall be readily available to the employee upon reasonable request.
- qualified benefit plans, trust records, employee notices and sales and purchasing records
- records of additions to or deductions from wages, unemployment compensation contributions and wage rate tables.
- when a piece or incentive plan is in operation, piece rates or an explanation of the incentive plan formula must be provided to employees. An accurate production record shall be maintained by the employer.
All required records must be in English and in ink or other indelible form, properly dated, showing the month, day and year and should be kept on file by the employer for at least three years at the place of employment or at a central location within the state of California. An employee’s records should be available for inspection by the employee upon reasonable request.

Discrimination in Employment on Basis of Sex: Two Years
Pursuant to California’s Equal Pay Act, California Labor Code Section 1197.5(d), “every employer shall maintain records of the wages and wage rates, job classifications and other terms and conditions of employment of the persons employed by the employer. All of the records shall be kept on file for a period of two years.”
Workers’ Compensation Benefits: Two Years to Five Years
In California, employers should retain the following documents for work place injuries: date-stamped copy of claim forms, report of occupational injury or illness, letter of denial of benefits to employee, all reports to the Division of Workers’ Compensation, records of benefits paid, estimate of future benefits, applications to the Workers’ Compensation Appeals Board, Orders & Awards of Workers’ Compensation Appeals Board, and all notices sent to the injured employee.
Employers should keep all of the above documents for at least five years after the date of injury, whether the claim is still active or closed. For all closed workers’ compensation claims, the employer should keep the above documents for at least two years from the date the claim closed. For open claims, the employer should keep the listed records for five years from the date of injury or last date for benefit payment, whichever is later.
All claim files shall be maintained at least until the latest of the following dates:
- five years from the date of injury
- one year from the date compensation was last provided
- all compensation due or which may be due has been paid
- if an audit has been conducted within the time specified in (a)(1), until the findings of an audit of the file have become final.
Open and closed claim files may be maintained in whole or in part in an electronic or other non-paper storage medium.
Healthy Workplaces Healthy Families Act of 2014: Three Years
The Healthy Workplaces, Healthy Families Act of 2014 is California’s new sick leave law that took effect January 1, 2015. The law makes any employee who works in California for 30 or more days on or after January 1, 2015 eligible for paid sick leave. An employer must keep records documenting the hours worked and paid sick days accrued and used by an employee for at least three years. Employers must also allow the Labor Commissioner access to these records. If an employer does not maintain adequate records pursuant to this act it will be presumed that the employee is entitled to the maximum number of hours accruable under this article, unless the employer can show otherwise by clear and convincing evidence.
For further information visit The California Department of Industrial Relations website.
Fair Chance Act (“Ban the Box”): Three Years
The Fair Chance Act went into effect on January 1, 2018 and is a California law that generally prohibits employers of more than 5 employees from inquiring into criminal backgrounds of applicants until after a conditional offer of employment is made. Employers cannot conduct any “direct or indirect” activity to gather criminal history from or about any applicant using any form of communication, including on application forms, interviews or Criminal History Reports. Employers must retain job applications and related information for three years.
For further information visit The California Department of Fair Employment and Housing website.
It is advisable for employers to permanently retain the following records:
- employment applications
- job offer letters
- records of pay changes since date of hire
- benefits or beneficiary designation or changes
- benefit request forms
- performance evaluations
- policy receipts with employee’s signature
- all employee training logs
- leaves of absence taken
- notice of union membership and dues deduction
- education records
- termination records and reasons therefor
- exit interviews
- awards to employees.
The following documents should be kept for at least five years:
- records complimenting an employee’s performance
- disciplinary action
- requests for transfer
- records of leave of absence taken.
The following records should also be kept:
- records regarding property issued to an employee (for the duration of the employment)
- verification of an employee’s references (three years)
- verification of employment provided to subsequent prospective employers (three years following termination)
- wage attachments/garnishment notices (six years)
- notices of union membership, dues check-off (four years).
The records and documents discussed under the relevant laws are not intended to be an all-inclusive list of documents an employer should keep. If there are documents not listed here that may be relevant to an employee, the employer should retain those documents as necessary. Additionally, the wages, taxes, medical leave, etc. laws discussed above require that an employer keep identical documents for different time periods. Therefore, remember that even though one law may only require you to retain a document for one year, another law may require you to keep that same document for four years. Further, if there is any investigation by a government agency, you must keep all records related to that investigation until the investigation is complete.
The CRA advises employers to seek the assistance of legal counsel or an accountant before destroying any employee documents.
Note that government contractors are subject to additional record keeping requirements not covered in this Industry Insight. When record-keeping requirements overlap, the longest requirement prevails. Because most retention periods are four years or less, and because the longest statute of limitations in California is generally four years, employers may be advised to retain all records at least that long.
