How to Write an Experience Letter: 2026 Guide

If you are an HR manager or business owner wondering how to write an experience letter for an outgoing employee, the good news is that the format is straightforward and the legal requirements are minimal. This guide walks you through every line of a clean, compliant experience letter so your company looks professional and your former employee has a document that holds up during background checks.

What is an Experience Letter?

An experience letter, also called a work experience certificate, is a formal document issued by an employer on company letterhead, confirming the period of employment, the job title held, and usually a short line about conduct. It is used by the former employee to prove their employment history during job applications, visa processing, university admissions, and background verification checks.

In India, nearly every white-collar and professional job application asks for experience letters from all previous employers, which is why issuing them promptly is an important part of the offboarding process.

How to Write an Experience Letter: Step by Step

Here are the steps a professionally drafted experience letter follows.

1. Start with the company letterhead

Use your official letterhead with the registered name, address, CIN, and logo. If you are a newer company without printed letterhead, build a clean PDF header with the same elements.

2. Add a reference number and date

A reference number (e.g., HR/EXP/2026/0047) lets your HR team retrieve the letter later, and the issue date must be on or after the employee's last working day.

3. Use "To Whom It May Concern" as the recipient

This is the most common opening in India because experience letters are shown to multiple unknown future readers. Skip addressing it to a specific person.

4. State the employee's full legal name

Use the name exactly as it appears on your payroll records and on the employee's Aadhaar or PAN, because background verification teams cross-check spellings.

5. Mention the employment period

Write out the exact joining date and last working day in "date month year" format (e.g., 14 June 2022 to 31 March 2026). Do not leave the dates as "three years".

6. State the final designation

Mention the role the employee held on their last working day. If the employee was promoted during their tenure, you can add a sentence noting the progression.

7. Add one or two lines about responsibilities or conduct

Keep this short and neutral. Words like "diligent", "sincere", and "hardworking" are safe. Avoid numeric achievements unless they are verifiable and already publicly shared.

8. Close with good wishes

A line like "We wish him the very best in his future endeavours" is standard.

9. Sign with name, designation, and contact

The signing authority should be the HR head, the founder, or a director. Include a contact line so a background verification team can reach out.

This is to certify that Ms. Shruti Agarwal was a full-time employee of Helix Data Solutions Private Limited from 7 August 2020 to 31 March 2026. Her last designation at the time of leaving was Senior Analyst in the Client Insights team.

During her tenure, Shruti was responsible for building recurring client dashboards, managing data quality for three enterprise accounts, and mentoring two junior analysts. We found her to be diligent, detail-oriented, and a collaborative team member.

She has been relieved from her duties after serving the notice period and completing all handover formalities. We wish her the very best in her future endeavours.

Tone and Language Tips

The experience letter should sound neutral and professional. Avoid words that sound like a sales pitch ("phenomenal", "world-class", "rockstar"). Avoid words that sound like criticism ("average", "satisfactory", "acceptable"). Stick with grounded, neutral praise. This keeps the letter credible and protects both the employee and the company.

Legal Points to Keep in Mind

There is no specific Indian statute that mandates the exact format of an experience letter, but the Shops and Establishments Acts of most Indian states require employers to issue some form of service certificate when an employee leaves. If the exit was involuntary or contested, consult your legal team before writing subjective commentary. A plain date and designation certificate is safer in such cases.

A digitally signed experience letter carries the same weight as a physical one under Section 3A of the Information Technology Act, 2000. Aadhaar OTP based eSign is specifically recognised as a valid signing technique under the IT (Electronic Signature) Rules, 2015.

Frequently Asked Questions

How long should an experience letter be?

One page is ideal. Background verification teams prefer short, fact-focused letters.

Should I mention the employee's salary?

No. Salary belongs in a separate salary certificate if the employee specifically requests one. Keeping salary out of the experience letter protects privacy.

Can I issue an experience letter to an employee who left years ago?

Yes. Indian employers routinely issue duplicate or delayed experience letters. Ask for the employee's ID and dates of employment, pull the record, and issue the letter on current letterhead.

Can a startup founder sign the experience letter?

Yes. For small companies, the founder or director is often the signing authority.

Is an eSigned experience letter accepted during background verification?

Yes. Major Indian background verification agencies accept Aadhaar eSigned experience letters because the signature is verifiable through the signing service.
