Federal Resignation Letter: Notice, Effective Date, and SF-50

A federal resignation letter needs three things to do its job: information that identifies you, a clear statement that you are resigning, and the specific date you want the resignation to take effect. Everything else in a federal resignation letter — what to include beyond those essentials, whether to give a reason, how much notice to offer — is either optional or a matter of workplace courtesy. Your right to resign is absolute under 5 CFR 715.202, and no agency can refuse the letter or force you to stay past your chosen date.¹

What to Include in the Letter

Keep the letter short and specific. Your HR office needs enough detail to process the separation without contacting you for follow-up questions after you’ve already left. Include:

Your full legal name, job title, grade or pay level, and the agency or component where you work.
A direct statement of intent. Write “I resign from my position,” not something that could be read as a request for transfer, detail, or retirement.
Your effective date, written as a specific calendar date. This drives every downstream calculation for pay, leave, and benefits.
The date you are submitting the letter and the name of the supervisor you are addressing.

Sign the letter and keep a dated copy for yourself. If you send it by email, keep the sent message and any read receipt or reply.

Whether to State a Reason

You can include a reason for leaving, but you are not required to. If you provide one, it goes on your SF-50 under remark code R19. If you don’t, the SF-50 notes that no reason was given under remark code S68.² Either way, the record shows a voluntary separation. If the reason is neutral — a new job, a move, family — stating it is fine. If it is a grievance, think carefully before putting it in writing on a document that becomes part of your permanent federal record.

Picking Your Effective Date

The regulation lets you choose any effective date you want.¹ A few practical points shape the smart choice.

Aligning the date with the last day of a pay period simplifies your final paycheck. Resign mid-period and you get a partial paycheck for the days worked, with your lump-sum annual leave payout processed as a separate payment later. Your FEHB coverage ends at the close of the pay period in which you separate no matter what day of that period your resignation lands, so an end-of-period date gets you the full value of your last premium.

Your unused annual leave is paid out as a lump sum after separation. The payment equals what you would have earned had you stayed employed for the length of your leave balance, and it is subject to federal, state, and Social Security tax withholding. Do not expect it quickly: OPM warns the leave audit can take several months, and the payment is issued separately from your final paycheck.³

Sick leave is different. It is not cashed out. If you return to federal service, your balance is recredited; if you eventually retire under FERS, remaining sick leave counts toward your annuity calculation.⁴ Burning it down before you resign forfeits both options.

How Much Notice to Give

Two weeks is the customary expectation, not a legal requirement. Your right to set your own effective date is not conditioned on any notice period.¹ Some agencies have internal policies or collective bargaining agreements that ask for longer notice; check before you submit. Failing to meet an internal expectation will not invalidate your resignation, but it can affect whether your supervisor is willing to serve as a reference later.

How to Submit the Letter

Give the letter to your immediate supervisor first. The supervisor then forwards it to the human resources office or personnel servicing center, which is the office that actually processes the separation and updates your Official Personnel Folder.² Some agencies accept email submission; others prefer a signed paper letter. Ask before sending.

Request written confirmation that HR received the resignation. Keep it with your copy of the letter. OPM’s own guidance recommends retaining a record of your resignation communication, and that record is what protects you if any dispute later arises about whether or when you resigned.⁵

What the SF-50 Will Show

Once HR processes the resignation, you receive a Standard Form 50 documenting the action. For a standard voluntary resignation, the nature of action code is 317.² Future employers, including other federal agencies, may review this form during background checks, so the coding matters.

Two special situations change what the SF-50 says:

Probationary employees. If you resign during a probationary period, the agency cannot place any adverse findings on your SF-50. That protection exists so agencies cannot tag new employees with negative records when they simply decide the job is not a fit.²

Resignation after a written notice of proposed adverse action. If you have received written notice of a proposed removal or other adverse action and then resign, the resignation still goes through, but remark code S31 will appear on the SF-50, noting that you “resigned after receiving written notice on [date] of proposal to separate for [reasons].” Without a written notice already issued, informal performance or conduct discussions do not trigger this remark. One further wrinkle: if a pending removal and your proposed resignation would take effect on the same date, the agency processes whichever action was submitted first, and a removal submitted first takes precedence over the resignation.²

If You Change Your Mind

You can ask to withdraw a resignation any time before its effective date, but the agency does not have to agree. Under 5 CFR 715.202(b), the agency may decline your withdrawal request for a valid reason, such as administrative disruption or having already committed to hiring a replacement. If it denies the request, it must give you the reason.¹

One thing the regulation explicitly prohibits: the agency cannot deny a withdrawal simply to avoid dealing with a pending adverse action against you. It needs a reason beyond preferring to let you leave.¹ Timing matters. The closer you are to the effective date, the stronger the agency’s case for disruption, so act early if you are reconsidering.

Before You Sign the Letter

A few obligations and choices are easier to address before you submit than after. None of them belong in the letter itself, but each one can catch a resigning employee off guard.

Service agreements. If you accepted a recruitment, relocation, or retention incentive tied to a service agreement, resigning before the agreed period ends will likely trigger a prorated repayment for the portion of the agreement you did not fulfill.⁶⁷ The agency can offset outstanding debts from your final salary and lump-sum leave payments.⁸

FERS contributions. If you have at least five years of creditable civilian service, you may be entitled to a deferred FERS annuity later — but only if you leave your retirement contributions in the system. Taking a refund of contributions permanently forfeits that annuity.⁹

FEHB coverage. Do not cancel your FEHB before separating. Letting it terminate through the separation process gives you a free 31-day extension of coverage; canceling first forfeits that extension.¹⁰

Post-employment restrictions. If you plan to work in lobbying, government affairs, or consulting involving your former agency, request an ethics opinion before your last day. Every former federal employee faces a permanent ban on representing outside parties before the government on specific matters they personally and substantially participated in, plus a two-year restriction on matters that were under their official responsibility during their last year of service. Senior officials face additional one- or two-year cooling-off periods on contacts with the former agency.¹¹

Reinstatement. If you might return to federal service, your reinstatement window depends on your status. Employees who completed the service requirement for career tenure, and veterans’ preference eligibles, have no time limit on reinstatement. Career-conditional employees who are not preference eligible must be reinstated within three years of separation.¹²

Handle these before the letter goes in, and the resignation itself becomes what it should be: a short, dated document that says who you are, that you are resigning, and when.
