How to Write a Resignation Letter (with Templates and AI Generator)

A resignation letter is the most consequential one-page document of any job you ever leave. Get it right and you leave with your reputation intact, your final paycheck on time, and a manager who is still willing to vouch for you in a future reference call. Get it wrong and the next six weeks of your professional life become noticeably harder.

This guide walks through exactly what a resignation letter should say, what it should avoid, when to send it, and gives you three plug-and-play templates for different situations. At the end, you can use our AI resignation letter generator to produce a polished, situation-specific version in about 30 seconds.

What a Resignation Letter Is For

A resignation letter is a formal written notice to your employer that you are ending your employment relationship. Its job is short and specific:

1. State that you are resigning
2. State your last working day
3. Leave the relationship on neutral or positive terms

That is the entire purpose. It is not a place to air grievances, list achievements, or explain in detail why you are leaving. Those conversations belong in an exit interview or a separate document. The resignation letter itself should be short, professional, and impossible to misread.

The most common mistake people make is treating the letter as either a victory lap or a parting shot. Neither serves you. The person reading it is almost always going to be your manager, an HR generalist, and eventually a future hiring manager doing a reference check. Write for that audience, not for the colleague who frustrated you.

When to Send a Resignation Letter

The standard sequence is:

1. Verbal conversation first. Tell your manager directly, ideally in person or on a one-to-one video call. Do not send a letter cold.
2. Written letter immediately after. Within an hour or so of the verbal conversation, send a written letter. This creates the paper trail HR will need.
3. Two weeks of notice in most professional roles, though senior or specialised roles may carry longer contractual notice periods. Check your contract.

If you are leaving under genuinely hostile circumstances — harassment, illegal conduct, or a hostile work environment — different rules apply, and you should consult employment counsel before drafting anything.

What to Include

A complete resignation letter has exactly five elements:

1. Your Statement of Resignation

Open with a clear sentence stating that you are resigning. No buildup, no caveats. Example:

Please accept this letter as formal notice of my resignation from the role of Senior Product Designer at Acme Corp.

2. Your Effective Last Day

Be specific. Use a calendar date, not a relative phrase. "My last day will be Friday, 29 May 2026" is better than "my last day will be in two weeks."

3. A Brief, Neutral Reason (Optional)

You do not owe your employer a reason. If you choose to give one, keep it neutral and forward-looking. "I have accepted a role that aligns more closely with my long-term career goals" is plenty. Avoid criticising the company, your manager, or your colleagues.

4. An Offer to Help with the Transition

A one-sentence offer to help with handover is professional and costs you nothing. It also makes the rest of your notice period much smoother because your manager now sees you as collaborative rather than checked out.

5. A Closing Thank-You

Even if the job was difficult, find one genuine thing to thank the company for — the skills you learned, the colleagues you worked with, the opportunity to grow. This is the line that future reference calls will remember.

What to Leave Out

Don't include	Why
Complaints about colleagues or managers	They follow you in references. Save them for the exit interview.
A list of your achievements	This is not a performance review.
Demands or ultimatums	They will not be granted by letter.
Your new employer's name	Optional and rarely useful — it can complicate counter-offers.
Detailed explanation of why you are leaving	A neutral one-liner is enough.
Emotional language	Even justified anger reads poorly in a one-page letter.

Three Templates You Can Copy

Template 1 — Standard Two Weeks Notice

Dear [Manager's name],

Please accept this letter as formal notice of my resignation from the role of [job title] at [company name]. My last working day will be [date — typically two weeks from today].

I am grateful for the opportunities I have had at [company name], particularly [one specific thing — a project, a skill, a team]. I have learned a great deal during my time here and I appreciate everything the team has invested in me.

I would like to help make this transition as smooth as possible. Please let me know how I can support the handover during my remaining time, including documenting current projects and briefing colleagues on outstanding work.

Thank you again for the opportunity.

Sincerely, [Your name]

Template 2 — Short, Direct, No Reason Given

Dear [Manager's name],

I am writing to inform you that I am resigning from my position as [job title], effective [date].

Thank you for the opportunity to be part of [company name]. I am happy to help train my replacement or document my current responsibilities to ensure a smooth handover.

Best regards, [Your name]

Template 3 — Immediate Resignation (Rare, Use Carefully)

Immediate resignation is appropriate in narrow circumstances — health emergency, family crisis, or a hostile work environment. It usually waives the standard notice period and may affect final-paycheck entitlements depending on your contract.

Dear [Manager's name],

Due to [brief, neutral reason — e.g., an unforeseen family situation that requires my full attention], I am writing to resign from my position as [job title], effective immediately.

I apologise for the short notice and I am happy to remain available by email for any urgent questions during the handover.

Thank you for understanding.

Sincerely, [Your name]

If you are leaving because of legal or HR issues, consult counsel before sending any version of this template.

Common Questions

Should I email or print and hand it over?

Email is now the norm for most office roles. Send it from your work email to your manager, copying HR. Keep the email body short — the letter itself is the attachment or a longer message in the body, your call.

What if my manager asks me to stay?

This is called a counter-offer. Industry data suggests that most people who accept counter-offers leave within twelve months anyway, often because the original reasons for leaving were not actually about money. Think hard before reversing course.

How much detail about my new job should I share?

The minimum. "I have accepted another opportunity" is enough. You are under no obligation to name the new employer or your new salary. Sharing too much can complicate the offer, trigger non-solicit clauses, or invite negotiation you did not ask for.

What if I am on a Performance Improvement Plan (PIP)?

You can still resign — a PIP does not lock you in. In some jurisdictions a voluntary resignation while on a PIP may affect your eligibility for unemployment benefits, so check before deciding whether to resign or wait out the PIP. The letter itself should still be neutral and short.

Does the letter need to be long?

No. One page or shorter is the right length. Many of the strongest resignation letters are four or five sentences. Length signals over-explanation, which signals discomfort.

The 30-Second Version

Once you understand the structure, you can write a resignation letter in five minutes by hand. But if you want to skip the blank page entirely, CraftMyLetter's resignation letter generator walks you through five short questions — your role, your manager, your last day, your tone preference, and any optional context — and outputs a polished letter you can copy, edit, or download as a PDF.

The first letter is free. You can adjust the tone (warm, neutral, or formal), regenerate as many times as you like, and the AI will keep the same structural backbone — clear statement, specific date, handover offer, brief thanks — while adapting the language to your situation.

Final Thought

The strongest resignation letters share one quality: they sound like the person you would want to hire again. Keep that lens on every line. The job market is smaller than it feels — the colleague you part with politely today is the hiring manager who returns your call in three years.
