Pros, Cons & Risk Analysis

Content reviewed October 17, 2026 · Educational reference

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. Potential NIIT reduction — depends on gain character, activity, and household income. Some active-business gain is already outside NIIT; installment interest requires separate analysis.
3. Scheduled, insurer-funded income — reduces reliance on a conventional buyer note, while retaining assignment-company, insurer, and any fallback-buyer risks.
4. Payment design — product-permitted start dates, balloons, and stepped amounts; life-contingent payments are not offered by every SIS provider.
5. Broader asset coverage than §1031 — businesses, practices, land, not just real property.
6. Potential administrative simplicity — compare professional fees, consultant compensation, embedded pricing, and net quotes; insurer-paid compensation does not make the economics costless.
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. Restricted access — payment terms generally cannot be changed unilaterally; any preselected death-acceleration or other contractual provision needs separate tax review.
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. Recapture taxed up front — §1245 and actual §1250 ordinary recapture are current under §453(i); unrecaptured §1250 gain is different and can be deferred.
6. §453A interest charge — evaluate qualifying obligations by sale-year group, the $5 million threshold, the applicable percentage, and farming/personal-use exceptions.
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.

Suitability matrix

Compare the same economic inputs

Ask for the cash-sale baseline and each proposed schedule using the same sale price, basis, selling costs, tax assumptions, and time horizon. Separate guaranteed payments from any nonguaranteed illustrations. Show the present value of after-tax cash flows, not only total nominal dollars.

Run scenarios with higher tax rates, inflation, shorter life expectancy, and a need for unexpected cash. Ask which charges or compensation are included in the quoted economics, which professional fees are separate, and what rights are lost after funding.

Situations requiring a different starting point

Sellers needing most proceeds immediately, holding excluded property, or already in receipt of the proceeds may have little usable SIS deferral. Entity liquidation, related-party transactions, earnouts, and a high-recapture asset mix require additional work before quoting. Check statutory exclusions and alternatives first, including §121, §1202, §1031, and qualifying farmland §1062.
