BLUF (Bottom Line Up Front)
Your state of residence (SOR) determines your state income tax for your entire military career - even when stationed in other states. Choose wrong (California, New York, Oregon) and pay 5-13% state tax for 20+ years. Choose right (Texas, Florida, Nevada, Washington, Tennessee) and pay $0 state tax forever. For an E-6 earning $50,000/year, that's $100,000-$130,000 in lifetime tax savings.
Change your SOR to a no-tax state at your first PCS opportunity. This is a one-time decision worth six figures.
Understanding State of Residence vs Duty Station
What is State of Residence (SOR)?
Your legal home state - where you file state taxes, register to vote, get driver's license, register vehicle, and claim domicile. This does NOT change when you PCS to other states.
What is Duty Station?
Where the military stations you temporarily. Could be anywhere. Changes every 2-4 years with PCS.
The Critical Difference
SCRA Protection: The Servicemembers Civil Relief Act protects you from being taxed by your duty station state. You ONLY pay state tax to your state of residence.
Example:
- SOR: Texas (no state income tax)
- Duty station: California (9.3-13.3% state tax)
- You pay: $0 state tax (SCRA protection)
Without SCRA (civilians):
- Live in California
- Earn $50,000
- Pay: $2,325-$6,650/year CA state tax
With SCRA (military):
- SOR: Texas
- Stationed in California
- Earn $50,000
- Pay: $0 state tax
This protection is the secret to military wealth building.

- State tax paid: $195,000+ (average 9.3% on career earnings)
- If had Texas SOR: $0 state tax
- Cost of wrong SOR decision: $195,000
How to Change Your State of Residence
Requirements to Establish New SOR
You must:
- Physically move there (get PCS orders to state, or declare it as home when joining)
- Get driver's license in new state (within 30 days of PCS)
- Register to vote in new state
- Register vehicle (if required by state)
- Update DEERS/finance (change SOR in military systems within 30 days)
- File state tax return as part-year resident (year of change)
Critical: Update SOR in myPay within 30 days of PCS to new state.
Step-by-Step Process (Example: Changing from CA to TX)
Background:
- E-5, currently stationed in California (4 years)
- SOR still California from pre-military
- Paying $1,920/year CA state tax
- Getting PCS orders to Fort Hood, Texas
Timeline:
30 Days Before PCS:
- Research Texas residency requirements
- Plan to change SOR upon arrival
Week 1 at Fort Hood:
- Visit DMV, get Texas driver's license (surrender CA license)
- Cost: $25
Week 2:
- Register to vote in Texas (online, free)
- Register vehicle in Texas (if required)
- Cost: $50-100 vehicle registration
Week 2:
- Log into myPay → Personal Information → State of Residence
- Change from California to Texas
- CRITICAL: Do this within 30 days of PCS
Week 3:
- Verify next LES shows TX as state (no state tax withheld)
- If still shows CA, call finance office immediately
Tax Time (Next Year):
- File California part-year resident return (Jan 1 - PCS date)
- File Texas return (none required - TX has no income tax)
- IRS Form 1040 (federal) as normal
Ongoing:
- Maintain TX residency for entire career (even when PCS elsewhere)
- Renew TX driver's license when stationed in other states (by mail or online)
- Never change SOR unless PCSing to better no-tax state
Common Mistakes When Changing SOR
Mistake #1: Not updating myPay
- Symptom: State tax still withheld on LES
- Fix: Update SOR in myPay, call finance, file amended return
Mistake #2: Changing SOR to duty station automatically
- Wrong: Every PCS, update SOR to new state
- Right: Keep no-tax SOR for entire career
- Impact: Paying state tax unnecessarily
Mistake #3: Not filing part-year resident returns
- When you change SOR mid-year, must file:
- Old state: part-year return (Jan 1 - move date)
- New state: part-year return (move date - Dec 31)
- Skipping = penalties, interest, tax problems
Mistake #4: Spouse has different SOR
- MSRRA allows spouse to claim your SOR
- But they must elect it (not automatic)
- File married filing jointly with your (no-tax) SOR
- Spouse working in duty station state = protected by MSRRA
Real-World Examples
Example 1: E-6, 20-Year Career
Scenario A: California SOR (Wrong)
- Career earnings: $1.1M (average $55K/year × 20 years)
- CA state tax: 6-9.3% average = ~$82,500 over 20 years
- Retirement: CA taxes military pension too
- Lifetime cost: $82,500 + ongoing pension taxation
Scenario B: Texas SOR (Right)
- Career earnings: $1.1M
- TX state tax: $0
- Retirement: TX doesn't tax military pension
- Lifetime savings: $82,500+ compared to CA
- Opportunity cost: $82,500 invested at 7% = $175,000 at retirement
Decision: Change SOR to Texas at first PCS = $175,000 richer at retirement
Example 2: O-4, 24-Year Career
Scenario A: New York SOR (Wrong)
- Career earnings: $2.1M (average $87,500/year × 24 years)
- NY state tax: 5-6.85% average = ~$126,000 over 24 years
- Retirement: $5,500/mo pension × 5.85% = $322/mo = $3,864/year × 25 years = $96,600
- Lifetime cost: $222,600 in state taxes
Scenario B: Florida SOR (Right)
- Career earnings: $2.1M
- FL state tax: $0
- Retirement: FL doesn't tax pension
- Lifetime savings: $222,600 compared to NY
- Opportunity cost: $222,600 invested at 7% = $567,000
Decision: Changing SOR from NY to FL = half a million dollars in wealth difference
Example 3: Dual-Military Couple
Situation:
- Both E-5, both from California originally
- PCS to Fort Bragg, North Carolina together
- Combined income: $110,000/year
Strategy:
- Both change SOR to North Carolina (no income tax)
- Alternative: Both change to Texas or Florida when next PCS there
- Spouse working in NC: protected by MSRRA (claim military SOR)
Savings:
- CA state tax on $110K: $6,380/year
- NC state tax: $0 (no income tax)
- Annual savings: $6,380
- 20-year career: $127,600 saved
Double Impact:
- Servicemember 1: saves $63,800
- Servicemember 2: saves $63,800
- Combined: $127,600 + compound growth = $320,000+
Special Situations
Deployed to Combat Zone
- SOR still applies (file state return from deployed location)
- CZTE (Combat Zone Tax Exclusion) makes federal income tax-free
- State tax: depends on SOR
- TX/FL/NV SOR: $0 state tax
- CA SOR: still owe CA state tax on combat zone pay (painful!)
- One more reason to have no-tax SOR
OCONUS Assignment (Germany, Japan, Korea)
- SOR doesn't change (you're overseas, not in another state)
- Keep your no-tax SOR
- File state return from overseas (most states accept APO address)
- Spouse working under SOFA: may be tax-exempt (country-specific)
Spouse Working in Different State (MSRRA)
Military Spouse Residency Relief Act (MSRRA):
- Spouse can claim servicemember's SOR
- Even if spouse works in different state
- Protects spouse from being taxed by duty station state
Example:
- Servicemember SOR: Texas (no tax)
- Stationed: California
- Spouse works in California, earns $55,000
- Without MSRRA: Owes $2,558 CA state tax
- With MSRRA: Claims TX SOR, owes $0 state tax
- Savings: $2,558/year = $51,160 over 20 years
Retirement Location
- SOR affects military pension taxation
- No-tax states: pension tax-free
- High-tax states: lose 5-10% of pension to state tax
- O-5 pension $6,000/mo, CA SOR: $558/mo state tax = $6,696/year × 25 years = $167,400
- O-5 pension $6,000/mo, TX SOR: $0 state tax = $0 lifetime
- Retirement location decision: $167,400 difference

- When you retire, consider moving back (no pension tax)
If You're in High-Tax State
- Plan to change at next PCS:
- Best: PCS to TX, FL, NV, WA, TN
- Acceptable: PCS to any of the 20+ states that exempt military retirement
- Change SOR immediately upon arrival
If You're Joining the Military
- Declare no-tax state as SOR immediately:
- TX, FL, NV, WA, TN, WY, AK, SD, NH
- Even if you've never lived there
- First duty station sets SOR (choose wisely)
If You Can't PCS to No-Tax State Soon
- Wait for opportunity:

Common Questions
Q: I'm from California originally. Can I change SOR to Texas even though I've never lived there?
A: YES. Military members can establish SOR in any state they're stationed. PCS to Texas? You can make it your SOR immediately. You don't need prior residency.
Q: Does changing SOR affect my leave address (where I spend vacation)?
A: No. SOR = legal domicile for taxes. You can take leave anywhere.
Q: My spouse is from New York. Do we have to have the same SOR?
A: No. Spouse can claim your (no-tax) SOR via MSRRA. File married filing jointly using your SOR.
Q: I'm retiring soon and want to move back to California. Should I change SOR?
A: NO. Keep no-tax SOR (TX, FL) even if physically living in CA. CA cannot tax your military pension if your SOR is elsewhere. This is legal and common.
Q: What if I'm in a high-tax state and never PCS to a no-tax state?
A: Request PCS to no-tax state. Texas has Fort Hood, Fort Bliss, Fort Sam Houston, Fort Cavazos, JB San Antonio. Florida has multiple bases. Even 1 PCS to change SOR = $100K+ lifetime savings (worth requesting).
Q: Do I lose any benefits by changing SOR?
A: No. Federal benefits (VA, GI Bill, TRICARE) are not affected. State-specific benefits (if any) might change, but rare.
Q: My home state is [high-tax state]. Won't I have to change back when I separate?
A: No. You can keep no-tax SOR after separation and retire anywhere. Your SOR is where you claim domicile, not necessarily where you physically live (check state domicile rules, but most servicemembers can maintain TX/FL SOR for life).
