Military pensions are earned benefits paid monthly for life once you meet service requirements, and the amount depends on your rank, years of service, and which military retirement system covers you
A military pension is not the same as Social Security or a civilian 401(k). It is a monthly payment that starts when you retire from active duty or the Reserve and continues for the rest of your life. The military operates two different pension systems depending on when you entered service: the High-3 system for those who joined before January 1, 2018, and the Blended Retirement System (BRS) for those who joined after. Both systems require you to serve a minimum number of years before you can draw a pension.
The pension is calculated using a formula that multiplies your base pay by your years of service and a percentage. For the High-3 system, the formula is 2.5% times your highest 36 months of base pay times your years of service. For the BRS, the calculation is similar but also includes a separate contribution account that works like a 401(k). Understanding which system covers you and how the math works will help you plan for retirement.
Key Takeaways
- Military pensions require a minimum of 20 years of active duty service (or equivalent time in the Reserve or National Guard) before you can receive monthly payments for life.
- The High-3 system uses your highest 36 months of base pay to calculate your pension; the BRS (for those who joined after 2018) adds a separate savings account that the military matches.
- Your pension is reduced if you receive a military disability rating from the VA, though you may be able to receive both under certain conditions through the Concurrent Retirement and Disability Pay (CRDP) program.
- Survivor Benefit Plan (SBP) is optional but allows you to continue payments to your spouse or children after your death, and you choose the coverage level when you retire.
- Military pensions are taxed as ordinary income on your federal and state tax returns, and some states do not tax military retirement income at all.
The High-3 System: How the calculation works
If you joined the military before January 1, 2018, you are covered by the High-3 system. Your pension is calculated by taking your highest 36 consecutive months of base pay (not including bonuses, housing allowance, or other special pay), multiplying it by 2.5%, and then multiplying that result by your total years of service.
For example, if your highest 36 months averaged $4,000 per month in base pay and you served 22 years, your calculation would be: $4,000 × 2.5% × 22 = $2,200 per month. You receive this amount for life, starting the month after you separate from active duty. If you served exactly 20 years, you receive 50% of your High-3 average. Each additional year adds 2.5% more.
The High-3 is straightforward but has no built-in savings component. Once you retire, the pension amount is fixed (though it increases annually with cost-of-living adjustments). You do not accumulate additional retirement savings through the military unless you contribute to the Thrift Savings Plan (TSP) on your own.
The Blended Retirement System: Active duty and matching contributions
Service members who joined on or after January 1, 2018, are enrolled in the Blended Retirement System (BRS). This system combines a smaller pension with a separate savings account that works similarly to a civilian 401(k). You contribute a percentage of your base pay to the BRS account, and the military matches a portion of that contribution.
The pension portion under BRS uses the same 2.5% formula as High-3, but it is calculated on your highest 36 months of base pay times your years of service. However, the multiplier starts at 2% for 20 years of service instead of 2.5%, meaning a 20-year career under BRS pays slightly less than High-3. The difference is made up by the savings account, which you can take with you if you leave before 20 years.
The military automatically contributes 1% of your base pay to your BRS account. If you contribute an additional 4% of your own pay, the military matches that 4%, for a total of 5% in matching contributions. This account grows with investment returns and belongs to you whether you stay for 20 years or leave earlier. When you retire, you can roll the BRS account into an IRA or keep it invested in the Thrift Savings Plan.
Minimum service requirements and vesting
You must complete at least 20 years of active duty service to receive a military pension. For the Reserve and National Guard, the calculation is different: you need 20 years of creditable service, which is based on retirement points rather than calendar years. A typical full-time Reserve or Guard member earns enough points in 20 calendar years, but part-time service takes longer.
There is no vesting period for military pensions the way there is in civilian jobs. Once you hit 20 years of service, you are may have access to to a pension. You do not have to stay longer to "earn" it. However, if you leave before 20 years, you receive nothing from the pension system under High-3. Under BRS, you keep your savings account contributions and military matches even if you leave early, but you do not receive the pension portion until you reach 20 years.
If you are medically discharged before 20 years due to a service-connected condition, you may receive a disability severance or disability retirement payment instead of a standard pension. This is handled through the VA disability system, not the pension system.
How disability ratings affect your pension
If you receive a VA disability rating after you retire, your military pension and disability compensation are normally not paid at the same time. The VA reduces your pension by the amount of your disability payment, a practice called offset. This means you do not receive both full amounts simultaneously.
However, certain service members can receive both their full pension and their full VA disability payment through the Concurrent Retirement and Disability Pay (CRDP) program. CRDP is available to retirees with a 50% or higher VA disability rating, or those with a 20% or higher rating who have at least 20 years of service. You must request CRDP; it does not happen automatically. The VA handles CRDP requests, and approval can take several months.
There is also the Concurrent Retirement and Disability Pay for Former Spouses (CRDP-FS) program for those with a 50% or higher rating who are no longer on active duty but receive military retirement pay. Understanding which program you may have access to for requires reviewing your specific discharge paperwork and VA rating.
Survivor Benefit Plan and what happens after you die
When you retire, you must decide whether to enroll in the Survivor Benefit Plan (SBP). This is optional, but it is an important decision because you cannot change it later without specific circumstances. SBP allows your spouse, children, or other beneficiaries to continue receiving a portion of your pension after your death.
You choose your coverage level when you retire. You can cover your full pension amount, a reduced amount, or opt out entirely. If you opt out and later want to enroll, you generally cannot do so unless you remarry or have a significant life event. The cost of SBP is deducted from your monthly pension payment. For example, if you elect to cover your spouse at the full amount, your monthly pension is reduced by roughly 6.5% to 10% depending on your age and your spouse's age at retirement.
If you die without SBP coverage, your pension stops. Your family receives no ongoing payments. If you have SBP coverage for your spouse, they receive a percentage of your pension for life (usually 55% of what you were receiving). If you cover your children, they receive payments until they reach age 22 (or 23 if enrolled full-time in college). SBP is a trade-off: you pay less each month if you opt out, but your family has no income from your pension if you die.
Taxes on military pension income
Military pension payments are taxed as ordinary income on your federal tax return. You must report your annual pension on Form 1040, and federal income tax is withheld from your monthly payment unless you request otherwise. You can adjust your withholding through the Defense Finance and Accounting Service (DFAS) if you want to pay more or less tax each month.
State tax treatment varies significantly. Some states, including Florida, Texas, and South Carolina, do not tax military retirement income at all. Other states tax it as regular income. A few states offer partial exemptions or deductions for military retirees. If you move to a different state after retirement, your tax liability may change. It is worth reviewing your state's tax rules before you relocate.
If you receive both a military pension and VA disability compensation, only the pension portion is subject to income tax. VA disability payments are not taxable. This is one reason why CRDP can be financially significant: you receive the full disability amount tax-free while also keeping your full pension.
Cost-of-living adjustments and pension increases
Military pensions increase annually with a cost-of-living adjustment (COLA). This adjustment is tied to the Consumer Price Index and is applied each January. COLA protects your purchasing power over time, so your pension does not stay frozen at the amount you received the month you retired.
The COLA is automatic and applies to all military retirees, regardless of which system you are under. It also applies to SBP payments and to any survivor benefits paid to your family. The exact percentage varies year to year based on inflation. In recent years, COLA increases have ranged from less than 1% to over 8%, depending on the inflation rate.
Frequently Asked Questions
Can I receive my military pension while still working?
Yes. Once you retire from the military with 20 or more years of service, you can work for a civilian employer, the federal government, or another military branch and still receive your full pension. There is no earnings limit or age requirement that affects your pension payment. Some retirees work part-time or full-time while drawing their pension.
What happens to my pension if I get divorced?
Your ex-spouse may be may have access to to a portion of your military pension depending on your state's divorce laws and the length of your marriage. The military does not decide this; your divorce decree does. The court order is sent to DFAS, which then splits your pension payment accordingly. The portion paid to your ex-spouse is taxed as their income, not yours.
Can I take my military pension as a lump sum instead of monthly payments?
No. Military pensions are paid only as monthly annuities for life. You cannot receive a lump sum or cash-out option. However, under the BRS system, your savings account can be withdrawn as a lump sum or rolled into an IRA when you retire. The pension portion itself must be taken as monthly payments.
What if I die before I reach retirement age?
If you die on active duty before completing 20 years of service, your family does not receive a military pension. However, they may receive a death gratuity (a one-time payment) and survivor benefits through the military's survivor assistance program. These are separate from the pension system and are handled by your branch's personnel office.
Does my military pension count as income for Social Security?
Your military pension does not affect your Social Security benefits directly. However, if you receive a military pension and also worked in jobs covered by Social Security, your Social Security payment may be reduced under the Government Pension Offset (GPO) or Windfall Elimination Provision (WEP) rules. These rules apply only if you also receive a government pension based on work you did not pay Social Security taxes on.
