Employment documents every employee should preserve and why they matter

An appointment letter may feel important on the day an employee joins, while a salary slip may appear relevant only until the next month. In reality, these records can become critical years later, when changing jobs, correcting provident fund records, filing a tax return, establishing gratuity eligibility or resolving a dispute over salary and service.Employees should therefore maintain a personal employment archive throughout their working life. It should cover not only documents received at joining and exit, but also statutory declarations, nominations and social-security records created during employment.1. Appointment letter and subsequent employment termsThe appointment letter is the starting point of the employment relationship. It ordinarily records the employee’s designation, date of joining, place of work, compensation, probation, notice period and other conditions of employment.Employees should preserve:The signed appointment or employment letterThe detailed compensation annexureDocuments confirming probation completion or employment confirmationLetters recording promotion, transfer or change in designationRevised compensation lettersAmendments to employment termsRelevant policy acknowledgementsWhy does this matter? An employee’s original terms may subsequently change several times. Preserving only the latest letter may make it difficult to establish the complete employment history.Appointment letters are also increasingly recognised as an important statutory employment record. For example, the notified Uttar Pradesh Occupational Safety, Health and Working Conditions Rules, 2026 require an appointment letter containing prescribed particulars, including the employee code, date of joining, wages, nature of duties and applicable EPFO and ESIC benefits.2. Salary or wage slips and supporting payment recordsEvery monthly salary or wage slip should be downloaded and stored outside the employer’s portal. It usually provides a month-by-month record of basic pay, allowances, attendance or paid days, overtime, statutory contributions, tax deductions and net payment.The wage-slip requirement is not merely an HR practice. Applicable wage rules may require employers to issue wage slips electronically or otherwise on or before payment of wages.The precise format may depend on the appropriate government and the rules applicable to the establishment.Employees should periodically compare the slip with:The amount credited to their bank accountTheir agreed salary structureEPF and ESI contribution recordsTax deducted and reflected in tax recordsOvertime, incentives, bonuses and authorised deductionsA salary slip can help establish both earnings and statutory deductions. However, a bank statement shows only the amount credited; it does not explain how that amount was calculated. Both records should therefore be preserved.3. PF Form 11, UAN and provident fund recordsAn employee joining an establishment covered by the Employees’ Provident Funds framework is generally asked to complete Form 11. It captures, among other things, whether the person was previously a member of EPF or EPS and, where applicable, the existing Universal Account Number, previous PF account details and KYC information.Employees should retain:A copy or acknowledgement of Form 11Their UAN and member IDs linked to itUAN activation details, without sharing or recording passwords insecurelyAadhaar, PAN and bank-account linkage statusAnnual or periodic EPF passbooksTransfer-claim acknowledgementsJoint declarations or correction requestsScheme certificates or pension-related records, where applicableClaim applications and settlement communicationsThe official EPFO portal provides access to the member passbook and claim status. EPFO also permits members to file and update electronic nominations during service.Employees should review their EPF passbook after joining a new employer and periodically thereafter. A mismatch in name, date of birth, date of joining, date of exit or previous employment details may otherwise remain unnoticed.Importantly, an EPF nomination is separate from a gratuity nomination. Updating one should not be assumed to update the other.4. ESI insurance number, e-Pehchan card and family detailsEmployees covered under the Employees’ State Insurance Scheme should preserve their insurace or IP number, e-Pehchan card and the registration particulars of eligible family members.The e-Pehchan framework supports identification of the insured person and registered family members for access to services.Relevant records include:Temporary identity certificate, where issuedESI insurance or IP numbere-Pehchan cardUpdated family particularsMedical or benefit-related certificatesClaim applications, approvals and payment recordsAccident or employment-injury documents, where relevantEmployees should not rely exclusively on continuing access to the employer’s HR portal after separation.5. Form 16 and annual tax recordsForm 16 is an important annual tax document for a salaried employee. Employees should preserve Form 16 issued by every employer during a financial year, particularly if they change jobs.They should also retain:Form 12BB and supporting declarations submitted to the employerProof of tax-saving investments and eligible deductionsRent receipts and landlord particulars submitted for HRA purposesForm 26AS and Annual Information StatementFiled income-tax returns and acknowledgementsTax-demand, refund or rectification communicationsThe Income Tax Department maintains a dedicated Form 16 resource and separate guidance for returns applicable to salaried individuals.Form 16 should not be viewed as an infallible record. Employees should reconcile salary and TDS information with Form 26AS and the Annual Information Statement before filing their return.6. Statutory nomination formsNomination forms often receive less attention than salary documents, although their importance is greatest when an employee is not available to clarify their wishes.Employees should preserve acknowledged copies of all applicable nominations, including:EPF and EPS nominationGratuity nominationESI family or dependant particularsEmployer group life and accident insurance nominationsSuperannuation or pension-fund nominationNPS nomination, where applicableWage, maternity-benefit or other statutory nomination forms prescribed under the applicable rulesUnder the Social Security (Central) Rules, 2026 , Form III is the prescribed nomination form. The same form will be used for a fresh nomination and modification of an existing nomination.A nomination should be reviewed following marriage, divorce, birth or adoption of a child, death of a nominee or any significant change in family circumstances. Employees should obtain an employer acknowledgement or retain the electronic confirmation. A form that was submitted but cannot later be traced may create avoidable difficulty.7. Leave, maternity and workplace-benefit recordsEmployees should retain significant leave and benefit records, particularly where they affect continuity of service or payment. These may include:Maternity leave application and approvalMedical certificates and fitness documentsAdoption, commissioning-mother or childcare-related approvals, where applicableLong-service, sabbatical or unpaid-leave approvalsEmployment-injury and disability-related recordsApproved work-from-home or remote-working arrangements where these change employment conditionsSensitive medical records should be stored securely and shared only where required.8. Resignation, acceptance and exit documentsAn employee should preserve both the resignation submitted and the employer’s response. A verbal resignation or an unrecorded discussion may not satisfactorily establish the agreed last working day.The exit file should include:Resignation email or signed letterEmployer’s acceptanceAgreed last working dayNotice-period waiver, recovery or buyout communicationHandover and no-dues acknowledgementsRelieving letterService certificate or experience letterFull-and-final settlement statementGratuity calculation and payment communication, where applicableLeave-encashment and bonus detailsFinal salary slip and bank-credit proofPF exit-date and transfer recordsA service certificate, experience letter and relieving letter may serve different purposes. The service or experience document generally records the period and nature of employment, while the relieving letter confirms that the employee has been released from service.Employees should check that the dates, designation and employer’s legal name are accurate.Practical exampleRiya changes employment after seven years. Four years later, she finds that her date of exit from the earlier employment was incorrectly recorded in her PF account. Her old HR portal is no longer accessible.Because she retained her appointment letter, salary slips, resignation acceptance, relieving letter, PF member details and full-and-final settlement, she has a coherent record of when her employment began and ended. Without these documents, resolving the discrepancy could be considerably harder.Build one secure employment archiveEmployees should create separate folders for each employer and organise records under joining, payroll, tax, social security, nominations, benefits and exit. Important documents should be downloaded before the last working day and retained in a secure personal location, with an encrypted backup.The practical rule is simple: preserve any document that establishes who employed you, on what terms, for what period, how much you were paid, what statutory deductions were made, which benefits covered you and who was nominated to receive them. A few minutes spent maintaining these records can protect years of employment, tax and social-security history.Employee document health checkAt least once a year, employees should verify:Are all appointment, increment and promotion letters available?Have salary slips and Form 16 been downloaded?Do salary deductions reconcile with EPF, ESI and tax records?Are UAN, KYC, bank and family details correct?Are all benefit nominations current and acknowledged?Are records from previous employers still accessible?Are employment documents stored securely outside the employer’s systems?Following an exit, have the service certificate, final settlement and statutory benefit records been collected?A well-maintained employment archive is not paperwork for its own sake. It is a personal record of an employee’s earnings, service, rights and financial security.(The author, Puneet Gupta is Partner, People Advisory Services Tax at EY India)You use AI every day.
