Chapter 9

Pros, Cons & Risk Analysis

A balanced ledger: nine benefits, thirteen risks and limitations, and a suitability matrix.

Nine benefits

  1. Capital-gains deferral & bracket management — spreading gain can drop the seller from 20% to 15% or even 0%.
  2. NIIT avoidance or reduction — keeping annual MAGI under $200k/$250k can avoid the 3.8% tax.
  3. Guaranteed, insurer-backed income — no buyer-default risk.
  4. Flexible payment design — deferred starts, balloons, stepped or lifetime income.
  5. Broader asset coverage than §1031 — businesses, practices, land, not just real property.
  6. Simpler than CRTs/DSTs/QOFs — often at no out-of-pocket cost (the insurer pays the consultant).
  7. Lock in yield in a high-rate environment.
  8. Estate planning & income smoothing — coordinate with Social Security, manage IRMAA, pass remainder to heirs.
  9. No reinvestment requirement — exit the sector entirely and receive income.

Thirteen risks & limitations

  1. Irrevocability — once closed, the schedule cannot be changed or accelerated.
  2. Interest-rate / opportunity-cost risk — a locked-in rate may trail markets.
  3. Inflation risk on fixed nominal payments (absent an index-linked variant).
  4. Illiquidity — the structured portion can't be reached or pledged.
  5. Depreciation recapture taxed up front — §1245 as ordinary income in year 1; §1250 at 25%.
  6. §453A interest charge on deferred obligations above $5M at year-end.
  7. Interest component taxed as ordinary income — up to 37%, vs. 20% LTCG.
  8. Buyer cooperation required — disclosing a preference for SIS can cost negotiating leverage.
  9. Counterparty risk — insurer solvency; guaranty limits below most balances.
  10. Ineligible assets — inventory, dealer property, publicly traded securities, losses.
  11. Related-party limits — §453(e) two-year resale; §453(g).
  12. Complexity & coordination — the structure must align with the tax strategy from day one.
  13. Future tax-rate risk — deferral locks the timing, not the future rate.
