I What a duty station actually is
Your official duty station is the location recorded on your SF-50 as the place you are officially assigned to work. Three things it is not:
- Not your home address. Where you live is irrelevant to locality.
- Not necessarily where you sit today. A teleworking employee whose SF-50 records an office has that office as their duty station.
- Not your agency's headquarters, unless that is what the record says.
A duty station change is a pay action — which means it is negotiable before it happens, documented when it happens, and difficult to revisit afterward.
If you have never looked at this field, look now. It is on your most recent SF-50, and reading them generally is covered in Topic 12.
II Everything it controls
| What it determines | Why it matters |
|---|---|
| Your locality pay area | 17.06% to 46.34% in 2026 — the single largest variable |
| Your payable rate | Same grade and step, potentially tens of thousands apart |
| Geographic conversion on promotion | Which schedule your old grade and step are re-priced against |
| Relocation entitlements | Whether a move is authorized and reimbursable |
| Travel and per diem | What counts as official travel versus a commute |
| Your High-3 | Locality is basic pay, so it feeds the annuity computation |
That last row is the one people discover too late. Locality pay is part of basic pay, and basic pay is what the High-3 average salary is built from. A duty station change late in a career reaches your annuity for the rest of your life.
III Geographic conversion
When your duty station moves to a location where different pay schedules apply, the agency must first convert you to the new location's schedule based on your position of record before the change, and only then apply any other pay action.
The order is mandatory, and on a promotion it works in your favor.
Why the sequence matters on a promotion
A GS-12 Step 5 in a Rest of U.S. duty station is promoted to GS-13 in the Washington-Baltimore area.
Geographic conversion runs first: the agency prices that GS-12 Step 5 at the Washington-Baltimore rate. Only then is the two-step promotion rule applied, computed from the higher converted figure.
"Different pay schedules apply" has a specific meaning: the change would cause you to gain or lose coverage under a locality rate schedule or a special rate schedule if you stayed in the same position of record. A move within the same locality area does not trigger it.
If your promotion involves a locality change, ask HR directly: "was geographic conversion applied before the two-step rule?" The answer should be immediate. Getting the order wrong understates your new rate, and that error then propagates into every future promotion computed from it. The full promotion mechanics are in Topic 39.
IV Moving up, moving down
Your grade and step do not change when your duty station does. The percentage applied to them does, and the effect runs both ways.
| Move | Effect on a GS-13 Step 5 |
|---|---|
| Rest of U.S. → Washington-Baltimore | +$17,400 per year |
| Rest of U.S. → San Jose–San Francisco | +$30,200 per year |
| Washington-Baltimore → Rest of U.S. | −$17,400 per year |
| Within the same locality area | No change |
There is no automatic protection against a decrease. Pay retention provisions exist in limited circumstances involving certain management actions, but they are narrow, they do not apply to voluntary moves, and they should never be assumed.
If a duty station change would lower your pay, ask specifically whether any pay retention applies to your situation and get the answer in writing. Do not infer it from the fact that the change was not your idea, and do not assume a hardship argument creates an entitlement. Locality mechanics generally are in Topic 02.
V Remote work as a pay action
This is where duty station changes most often catch people, because the arrangement is presented as a schedule question.
| Arrangement | Duty station | Locality |
|---|---|---|
| Telework — some days from home, office remains official | Unchanged | Unchanged |
| Approved fully remote — duty station changed to home | Changed | Changes to home area rate |
Reporting at the office at least twice per pay period has generally been the standard for keeping an office duty station.
Before agreeing to any remote arrangement, ask for confirmation of what your official duty station will be and what locality percentage will apply. Those two facts determine whether this is a flexibility or a pay cut. A GS-13 Step 5 moving from Washington-Baltimore to a Rest of U.S. home location loses roughly $17,400 a year — permanently, and it carries into the High-3. Telework specifics are in Topic 21.

VII Relocation entitlements
Whether a physical move is reimbursable turns on a single distinction: is the move in the interest of the government, or for your own convenience?
| Type of move | Relocation entitlement |
|---|---|
| Management-directed transfer, government interest | Generally supports authorization |
| You applied for and accepted a position elsewhere | Frequently treated as your own benefit; may carry none |
| Approved remote work at your request | Generally none |
| New appointment from outside government | Varies; may be authorized for hard-to-fill positions |
The determination is recorded in your travel authorization, not inferred from circumstances. Potential entitlements can include household goods shipment, temporary quarters, house-hunting travel, real estate transaction expenses, and a relocation income tax allowance — but only where authorized.
"Is relocation authorized for this position, and at what level?" is a question with a factual answer that someone can give you before you accept. Asking after you have accepted converts it from a negotiation into a request. A relocation incentive is a separate authority from relocation expenses, and both are worth asking about — see Topic 20 and Topic 15.
VIII When the agency initiates it
Agencies do direct reassignments and relocations, and a management-directed change is meaningfully different from a voluntary one.
- Relocation entitlements are more likely to be authorized where the move serves the government's interest.
- Procedural rights may attach depending on the circumstances, particularly for an involuntary geographic reassignment.
- Declining a directed reassignment can have consequences, up to separation in some circumstances.
- Bargaining unit employees may have negotiated protections — check with your representative, and confirm your current bargaining unit status first, since it may have changed. See Workplace Topic 06.
If a directed change would materially reduce your pay or require an actual move, that is worth a conversation with your union representative or your own counsel before you respond in writing. Options for representation are in Workplace Topic 45.
IX The High-3 consequence
Locality pay is part of basic pay, and basic pay is what your High-3 average salary is computed from. That makes a duty station change near retirement a decision with a very long tail.
The same move, two different times
A GS-13 Step 5 takes an approved remote arrangement out of Washington-Baltimore to a Rest of U.S. location, losing about $17,400 a year.
Fifteen years from retirement: the salary reduction is real, but the High-3 is computed from the final three years and will reflect wherever they are working then.
Two years from retirement: the reduction lands squarely inside the High-3 window. At 30 years of service and the 1.1 percent multiplier, roughly $17,400 off the average costs about $5,700 per year of annuity — for life.
The reverse is equally true and less often used: a move into a higher-locality duty station in your final three years is one of the most effective High-3 levers available. See Topic 35.
X The five things to confirm
Every one of these is a factual question your HR office can answer before you commit, and every one is harder to revisit afterward.
- What will my official duty station be? The exact location that will appear on the SF-50.
- What locality percentage applies there? Not the area name — the number.
- What will my payable rate be? The actual annual figure, not a percentage change.
- Is relocation authorized, and at what level? Recorded in the travel authorization.
- What is the effective date? It determines when the pay change begins and which pay period it lands in.
If a promotion is involved, add a sixth: will geographic conversion be applied before the two-step rule?
Email is enough. A short message confirming your understanding of these five points, sent before you accept, creates a dated record and gives the other person a chance to correct anything you have wrong. That is ordinary professional practice, not an adversarial move — and if the answer later turns out different from what you were told, you have the exchange. See Workplace Topic 44.
XI The change nobody tells you about
Not every duty station change arrives as an offer. The field can be updated administratively during a reorganization, an office consolidation, a lease change, or a systems migration — and nobody is obligated to draw your attention to it.
Situations worth a check afterward:
- Your office relocated, even a short distance — locality boundaries can run between adjacent counties.
- Your component was reorganized or realigned under a different office.
- You were reassigned without a physical move.
- Your agency consolidated facilities or closed a location.
- You signed a telework or remote agreement of any kind.
Read the duty station field on every SF-50 you receive. It takes seconds. If it changed and you did not expect it, ask in writing immediately — a pay error caught in the same pay period is an administrative correction, while the same error found two years later is a claim.
XII The playbook
| Situation | What to do |
|---|---|
| Offered remote work | Confirm the duty station and locality in writing before agreeing. |
| Promotion involving a locality change | Confirm geographic conversion runs before the two-step rule. |
| Move would reduce your pay | Ask specifically whether pay retention applies. Never assume it. |
| Applying to a position elsewhere | Ask whether relocation is authorized, at the offer stage. |
| Management directs a reassignment | Different entitlement rules apply. Talk to your representative before responding. |
| Within three years of retirement | The change lands in your High-3. Model the annuity effect, not just the salary. |
| Office moved or reorganized | Check your SF-50 duty station field afterward. |
| Duty station changed unexpectedly | Raise it in writing in the same pay period. |
Before you agree to anything
- Find the duty station field on your current SF-50 and confirm which locality area it maps to.
- Get the new duty station, locality percentage, and resulting payable rate in writing before agreeing.
- Ask whether relocation expenses are authorized and at what level — it is recorded in the travel authorization.
- Confirm the effective date and which pay period the change lands in.
- If a promotion is involved, confirm geographic conversion will run before the two-step rule.
- If pay would decrease, ask specifically whether any pay retention applies. Do not assume it does.
- If you are within three years of retirement, model the High-3 effect rather than only the salary change.
- For a management-directed reassignment, check your bargaining unit status and talk to a representative first.
- Check your SF-50 after any office move, reorganization, or consolidation — the field can change quietly.
- Raise any unexpected change in writing in the same pay period, while it is still a correction rather than a claim.
Frequently asked questions
It is the location recorded on your SF-50 as the place where you are officially assigned to work, and it is the field that determines your locality pay area. It is not necessarily where you physically sit on a given day, and it is not your home address. An employee who teleworks three days a week from home but whose SF-50 records an office location has that office as their duty station. Because a single field drives your locality rate, your relocation entitlements, and part of your eventual annuity, it is worth knowing exactly what yours says.
When your duty station moves to a location where different pay schedules apply, the agency must first convert your existing grade and step to the pay schedule for the new location, based on your position of record before the change, and only then apply any other pay action. On a promotion that also involves a move, this matters a great deal: your old grade and step are re-priced at the new location first, and the two-step promotion rule is computed from that converted figure rather than from your old duty station's rate. The ordering is mandatory and it works in your favor.
Generally yes, if the change is to your official duty station. Locality follows the duty station, so moving from a 33.94 percent area to a 17.06 percent area reduces payable pay substantially — on a GS-13 Step 5 that is roughly $17,400 a year. Your grade and step do not change; the percentage applied to them does. In limited circumstances involving certain management actions, pay retention provisions can apply, but they are narrow and should never be assumed. Ask specifically before agreeing to anything.
It can, and that is the whole financial question. If an approved fully remote arrangement changes your recorded duty station to your home location, your locality changes to that area's rate. Ordinary telework, where your official duty station remains the office, does not change your locality — reporting at the office at least twice per pay period has generally been the standard for keeping an office duty station. Get the treatment stated in writing before agreeing, because this is processed as a pay action rather than as a schedule change.
It depends heavily on whether the move is in the government's interest or for your own convenience. A management-directed transfer in the interest of the government generally supports relocation authorization, while a move you requested is frequently treated as being for your own benefit and may carry no entitlement at all. The distinction is recorded in your travel authorization, not inferred from circumstances, so the operative question at the offer stage is whether relocation is authorized in writing — asking afterward is much harder.
Locality pay is part of basic pay, and basic pay is what your High-3 average salary is computed from. A move to a higher-locality duty station in your final three years raises the average that multiplies every year of service in the FERS formula, and a move to a lower one lowers it. That makes a late-career locality move one of the more effective levers available — and makes an approved remote conversion out of a high-locality area within three years of retirement an expensive decision that reaches well beyond the salary reduction itself.
Agencies do direct reassignments and relocations, and a management-directed change is not the same as a voluntary one — different rules on relocation entitlement apply, and depending on the circumstances an involuntary geographic reassignment may carry procedural rights. Separately, a duty station field can be changed administratively during a reorganization or office consolidation without anyone drawing your attention to it. That is why the practical advice is to check your SF-50 after any organizational change, not only after a move you initiated.
Five things, in writing: what the new official duty station will be, what locality percentage applies there, what your resulting payable rate will be, whether relocation expenses are authorized and at what level, and the effective date. If a promotion is involved, also confirm that geographic conversion will be applied before the two-step rule. Every one of these is a factual question your HR office can answer before you commit, and every one of them is significantly harder to revisit after the action has been processed.
