IRC §453 — The 100-Year-OldTax Code Most California CPAs Forget About

1926 — The Original Installment Sale Rule

In the early 1900s, American farmers faced a real problem: when they sold a tract of land for $50,000 but only collected $5,000 a year over 10 years, the IRS forced them to pay tax on the FULL $50K in Year 1 — long before they had the cash to pay it. The Revenue Act of 1926 fixed this by formally codifying the installment-sale method: tax is owed pro-rata, in the year each payment is actually received.

That core principle has been on the books for nearly 100 years.

1969 — The Charitable Remainder Trust (§664)

Congress added Internal Revenue Code §664 — the Charitable Remainder Trust. Codified the rules for trusts that sell appreciated assets tax-free and pay income to a non-charitable beneficiary, with the remainder going to charity. The CRT and the §453 installment sale are the two foundational structures California sellers still use for capital-gains tax planning.

1980s — Structured Settlements Industry Builds the Infrastructure

In response to large personal-injury awards, A-rated insurance carriers built the "structured settlement" industry — a third-party assignment company would take over the obligation to pay the injured party in installments, funded by an annuity from the carrier. This let plaintiffs collect tax-free §104(a)(2) damages over time instead of in one lump.

The same assignment infrastructure — carrier as third-party obligor — was the foundation for the modern Structured Installment Sale.

2005 — Rev. Proc. 2005-26: Modern SIS Validation

The IRS published Revenue Procedure 2005-26, confirming that the carrier-assignment structure used by structured-settlement specialists qualifies for installment-sale treatment under §453 for taxable sales (not just §104 personal-injury settlements). This was the official green light for "SIS" placement in commercial real-estate, business-sale, and farm-sale transactions.

2010s — SIS Expands to California Real Estate & Business Sales

As California capital-gains tax rates climbed (state top rate to 13.3% in 2012, plus the 1% Mental Health Services Tax above $1M from Prop 63 in 2004), high-net-worth California sellers began using SIS structures to spread the bite. Major A+ AM Best-rated annuity carriers and specialty indexed-annuity carriers built out commercial-sale-specific products to meet demand.

Why Your CPA May Have Never Mentioned It

Three reasons:

• Specialty placement.SIS requires a carrier-appointed structured-settlement broker — a tiny niche of ~200 specialists in the entire U.S. Most CPAs have never met one.
• No incentive for the CPA.A CPA earns nothing from recommending an SIS. They get paid to file your tax return — and a cash sale is the easier return to file.
• "Safe" = familiar.Escrow officers and closing attorneys default to lump-sum cash because that's what they've done 10,000 times. SIS requires explaining one extra document at closing.

The result: a 100-year-old, IRS-codified, court-tested structure that could save the average California seller $200K-$700K is recommended on fewer than 1% of taxable California real-estate sales. Not because it doesn't work. Because the existing advisory team rarely has the appointments to place it — or the fee structure to bother surfacing it.
