The SBP vs life insurance question — the classic "should I take the DFAS annuity or buy term to replace it?" — has been argued to death on product features (inflation adjustment, guaranteed continuation, remarriage rules). But most side-by-sides skip the single largest structural difference between the two products: their tax treatment.
SBP payments are fully taxable as ordinary income to the surviving spouse. Life insurance death benefits are entirely tax-free. That gap can be worth 15–25% of the annuity amount, and it changes the honest answer to the comparison.
SBP tax treatment
The Survivor Benefit Plan pays a monthly annuity to the retiree's beneficiary — typically the spouse — equal to 55% of the covered base amount (usually the retiree's monthly retired pay). SBP payments are reported to the beneficiary on Form 1099-R and are taxable as ordinary income at the beneficiary's federal (and, where applicable, state) marginal rate.
SBP premiums paid during the retiree's lifetime come out of retirement pay pre-tax — reducing the retiree's taxable income by the premium amount. So SBP is tax-advantaged going in, taxed on the way out.
Life insurance tax treatment
Under 26 U.S.C. § 101(a), "gross income does not include amounts received... under a life insurance contract, if such amounts are paid by reason of the death of the insured." Death benefits are 100% tax-free to the beneficiary — no federal tax, no state tax.
Premiums, by contrast, are paid with after-tax dollars — no deduction. Life insurance is taxed going in (indirectly, since premiums come from taxed dollars), tax-free on the way out.
A concrete example
Retiree elects full SBP coverage on $5,000/month retirement pay. Beneficiary receives $2,750/month annuity ($5,000 × 55%) on the retiree's death.
- SBP: $2,750/month gross → assuming a 22% federal marginal rate and no state tax → ~$2,145/month net.
- Equivalent tax-free income needed: $2,145/month, or ~$25,740/year tax-free.
- A $500,000 term life policy at 4% withdrawal yields ~$20,000/year in perpetuity — not enough to replace SBP's post-tax value, even without inflation adjustment.
- To match SBP's inflation-adjusted post-tax payout for a 30-year retirement, the retiree would need roughly $650,000–$750,000 of term/perm insurance — often more than a healthy 40-something can affordably buy.
When SBP still wins despite the tax
- Inflation protection. SBP is COLA-adjusted; a fixed insurance benefit erodes at 2-3% inflation.
- Guaranteed for life. Term insurance ends at policy expiration; SBP continues for the beneficiary's lifetime (subject to remarriage rules).
- No underwriting. SBP has no medical exam; a retiree in poor health can still enroll.
- Government backing. SBP is backed by the U.S. Treasury; insurance is only as strong as the insurer's credit rating.
FAQs
Are life insurance CASH VALUES tax-free too?
Cash-value withdrawals up to basis (total premiums paid) are tax-free. Withdrawals above basis are taxed as ordinary income. Death benefit remains tax-free.
What about VGLI or a private term policy from SGLI conversion?
Same tax rule as any life insurance: death benefit tax-free.
Does SBP get taxed differently for former-spouse SBP?
No — former-spouse SBP annuity is taxable to the ex-spouse the same way as spouse SBP.
