Each card below is an illustrative seller profile — not a past client of mine — showing what the SIS / CRT math looks like for that situation. The break-even yields (typically 7-11%) are what cash would need to earn guaranteed for the full term to match the structured path. No conservative investment pays that guaranteed.
The seller is at $200K current income — bracket compression is partial. But they're retiring in 3 years. A deferred-start SIS means zero gain recognition for 3 years (while still earning $200K). At age 65, payments start, income drops to $80K, and the bracket compression jumps to MAXIMUM.
This seller is 45 — well under 59½. SIS payments are §453 installment income, NOT §72(q) annuity income, so there's no 10% early-withdrawal penalty. A 20-year SIS pays them until age 65 with no penalty exposure. Cash-into-MYGA at age 45 would face the §72(q) penalty on any withdrawals.
The seller is 75. A 30-year structure runs to age 105 — beyond realistic life expectancy. 10 years aligns with the seller's planning horizon, generates higher monthly income, and preserves spousal continuation (period certain). For older sellers, shorter SIS structures with higher monthly income are often the better fit.
This seller mentioned wanting to support their hospital. A CRT funded with the property would eliminate the entire $1.04M capital gains tax bill AND generate a $500K-$700K charitable deduction (varies with age + payout rate), AND pay them lifetime income, AND leave the remainder to their hospital. Often beats SIS net economics for charitably-inclined high-income sellers — see the calculator's CRT scenario.
The §1250 recapture is recognized in Year 1 regardless of the SIS — it cannot be deferred. The seller takes ~$310K in cash at closing to pay the recapture tax (25% federal + 9.3% CA = $283K cash needed). The remaining $4,190,000 is structured. The deferrable gain ($3.3M) is what gets the bracket-compression benefit, spread over 25 years.
Premium structured cannot exceed $5M without triggering the §453A interest charge (annual interest on deferred tax above the threshold). The fix: take $3M as cash at closing, structure exactly $5M with the carrier. Cash carveout covers the §121-excluded portion's tax burden plus liquidity for the seller's next home purchase. The $5M structured premium gets all the bracket-compression benefits at zero §453A cost.
