How to Write a Resignation Letter: Templates & Notice Rules (2026)

Related guide: Two Weeks’ Notice → — the short-form version of the same letter, and when it’s the right call.

What every resignation letter needs

A clear statement that you are resigning your position.
Your last working day, stated as a date — this is the single most important line.
A reason — only if you want to. One neutral sentence is plenty; you are never required to explain.
An offer to help transition — train a replacement, document open work.
A brief thank-you and your signature. Keep the whole thing to a few short paragraphs.

How much notice should you give?

In most U.S. jobs, employment is at-will, which means two weeks' notice is a widely expected professional courtesy rather than a legal requirement. But your situation can change that: an employment contract, a union agreement, or a company handbook may require a specific notice period, and senior or specialized roles often expect more than two weeks. Check your offer letter and handbook before you set a date — then give the notice your situation actually calls for.

Keep it short, professional, and un-burned

Whatever your reasons for leaving, the letter is not the place to air them. It becomes part of your personnel file, it's what a future reference desk reads, and a measured, gracious tone costs you nothing and protects everything. Save the candid feedback for an exit interview if you choose to give it — and keep the letter to the facts: you're resigning, here's your last day, here's how you'll help.

Common questions

Do I have to give a reason for resigning?
No. A resignation letter is valid with nothing more than a clear statement that you're leaving and your last day. If you choose to give a reason, one neutral sentence — “to pursue a new opportunity,” “for personal reasons” — is all anyone expects.

Is two weeks' notice legally required?
In most at-will U.S. jobs, no — it's a strong professional norm, not a law. The exception is when a contract, union agreement, or handbook sets a required notice period, so check yours before choosing a last day.

Can I resign by email or does it have to be a letter?
Either can work, but a signed letter (sent or attached to an email) is the cleaner record. However you deliver it, keep a dated copy for yourself — it's your proof of when and how you gave notice.
