How to write a formal resignation letter

People resign for many reasons: a better role, a move, school, or a job that is hurting their well-being. Whatever the motivation, most employers still expect a formal resignation letter so the departure is official for managers and HR.

Leaving well matters as much as leaving at all. A short, professional letter protects your reputation, documents your last day, and sets the tone for your notice period — even when emotions are mixed.

This guide covers why the letter exists, what to include (and skip), how to write each section, copyable examples, and how to deliver notice.

What is the purpose of a formal resignation letter?

Resigning means you no longer wish to stay employed in that role. Most employers want that decision in a professional document — printed or meant to be printed — that states your intent and your last day.

These are the main reasons a formal letter of resignation is expected:

• It creates a written record that you gave notice in line with the employer's notice policy — often at least two weeks — and is usually kept in your HR file.
• It may matter later if dates or notice periods are disputed.
• It helps other managers and teammates learn officially, instead of through rumors.
• It sets the tone for your remaining time and for any future relationship with the company.

Is the formal resignation letter enough?

Best practice is to tell your manager you are resigning before you hand over the formal letter. That conversation lets them ask practical questions and keeps the relationship more open.

Following up in writing makes the decision official for the reasons above. Your manager should not be blindsided by an unexpected email if you have already spoken. Some employers also schedule an exit interview after the letter is on file.

What to include in your formal resignation letter

Operations need clear facts before and after you leave. Keep the letter short and factual.

What your formal resignation letter should include

• A brief statement of gratitude. Leaving on a good note helps you, coworkers, and your manager. Keep it short — no gushing essays.
• One or two “helpful handoff” lines. Without overpromising, say you will finish what you can, update teammates on open work, and (if true) help recruit or train a temporary or permanent replacement.

Writing a formal letter of resignation

A short resignation letter should not take long. Include the essentials and little else. Typical sections:

• Greeting
• Introduction
• Reason for leaving (optional)
• Statement of gratitude
• Offer to help smooth the transition
• Conclusion
• Sign-off

Greeting

Address the person who should receive notice: your manager, a department head, or HR, depending on size and policy. Use Dear (First Name) or Dear Mr./Ms. Surname as fits the culture.

Introduction

State your resignation clearly. Include language such as “Please accept this letter of resignation,” plus your title, company name, and last working day. Those details are obvious to the recipient but matter for a formal record.

Dear Brian,

Please accept this letter of resignation as formal notice of my intention to leave my role as a project manager in the JCT Ltd New York office. My last day will be January 4, 2023.

You may add a neutral reason if it is not critical of the employer. Example:

As discussed, I have decided to return to education and will be starting my BSc in Engineering in early 2023.

Showing gratitude in a professional resignation letter

Keep the letter professional. If you were treated unfairly, the resignation letter is not the place to litigate it — that belongs in a calm conversation or exit interview. When the experience was largely positive, a short thank-you is appropriate:

I have enjoyed my time at JCT Ltd and have met colleagues who became lasting friends. This is a company that values its people, and it has been a pleasure to work here.

Offer to help smooth the transition

Add practical help you can actually deliver:

I have an outstanding project that will be completed by December 28. I am also happy to train a new team member if needed.

Conclusion

Close on a forward-looking note:

I wish you and the rest of the JCT team continued success, and I look forward to staying in touch.

Signing off your resignation letter

Choose a sign-off that matches workplace culture: “Sincerely,” “Best,” or “Thanks,” followed by your name.

Copy and edit the sample below with your details. For a polished layout, draft in a cover letter template and replace the body text with your resignation wording.

Dear Jan,

Please accept this letter of resignation as formal notice of my intention to resign from my position as account manager at Best Group, in the Boston head office. My last day will be June 3, 2023.

As mentioned in our earlier conversation, my spouse has accepted a promotion in Seattle, and we decided the relocation would be right for our family.

I want to thank you for the chance to grow in a role that was both interesting and rewarding. I learned a great deal from my manager and colleagues, who were consistently supportive. I am grateful for the positive experiences I had at Best Group.

During the next two weeks, I will finish as many projects as possible and bring other teammates up to speed on open tasks. Please let me know if I can help recruit or train a successor, or support the transition in any other way.

Thanks again, and best wishes for the future.

Sincerely,
John

The letter stays formal and ends positively. That approach makes a future return or reference far more likely than a bitter exit.

Top tips for dealing with resignation

• End on a high note. Keep language positive and professional even when the job was hard. A clean exit is always better than a scorched-earth one.
• Prepare for a mixed reaction. Some managers wish you well; others take the news poorly. Stay calm and professional either way.
• Support next steps. Be ready to document work, train coverage, and finish priority tasks during your notice period.

How to send your resignation letter

When possible, deliver notice in person (or on a video call) and follow with email so there is a digital trail. If you work remotely, email your manager and copy HR as your policy requires — after you have spoken first. A surprise resignation email alone rarely looks professional.

Set the letter up with a clear opening, a brief middle, and a courteous close. Stay positive, offer realistic transition help, and expect that not every manager will celebrate your news. Pair a clean exit with an updated MakeResume resume so your next applications are ready.
