Two ways to fund LTC

How to Pay for Long-Term Care

70% of 65-year-olds need LTC. California memory care runs $8,500 to $14,000/month and is rising 3 to 5%/yr. Two ways to fund it: SIS monthly payments cover the bill directly, OR an asset-based LTC policy delivers a 3-5× LTC pool (with a death benefit if you never need care). Plus the "stack both" case.

Annuity mechanics · §453 vs §72

The SIS uses an annuity, but it's NOT a SPIA. Period-certain only (no lifetime guarantee), taxed under §453 gross-profit ratio (LTCG rates) not §72 exclusion ratio (ordinary income).

The "assignment company," explained

What is the Assignment Company?

The entity that legally takes on the buyer's payment obligation isn't a mysterious third party. It's usually an affiliate of the highly rated insurer that issues the annuity, and it is the company that owes you the payments. Covers assignment companies and their subsidiaries, why the structure exists (§453, §453B), how the corporate map looks, and how to verify any of them in 30 seconds on SEC/NAIC.

"Why not just take payments from the buyer?"

The most common SIS pushback: "If I'm OK getting paid over time, why bring an insurance carrier in?" 10 reasons it almost always goes wrong: buyer credit risk, divorce/death/bankruptcy interception, §453B prepayment trap, foreclosure costs, state-line enforcement issues, buyer-discount expectation. With the SIS contrast for each.

Lesser-known SIS benefits

12 benefits of SIS most people don't know

Asset protection from creditors (CCP §704.100), zero ongoing AUM fees (~$500K saved over 25 years), Social Security claiming flexibility, probate avoidance, NIIT cliff avoidance, IRMAA planning (both ways), state-tax arbitrage on post-move interest if you move to TX/NV/FL, DAF/charitable compatibility, no RMDs, and IRD/§691(c) inheritance treatment. These are the reasons CPAs who understand the structure keep recommending it.

📚 Get the free Seller's Guide to §453 + a fit-check

A plain-English guide for sellers on how a structured installment sale defers the tax when you sell a business, practice, or property. It covers the math, the alternatives, and how to tell if your deal fits.

Leave your details and the PDF downloads right away. Within one business day Hans will email a preliminary read on which structure fits your deal. No retainer. On a funded structure, the insurer pays a one-time commission of about 4% of the amount structured to the brokerage firm that places it (Hans’s share is about 2.4%; no trail). It is built into the annuity pricing, not a separate fee.
