5.8 Like-Kind Exchanges, Insurance Tax Rules & Coordinating Multi-Account Contributions
Key Takeaways
- After the Tax Cuts and Jobs Act, IRC §1031 like-kind exchange treatment is available only for real property held for productive use in a trade or business or for investment — machinery, artwork, collectibles, cryptocurrency, and partnership interests no longer qualify.
- The §1031 clock is jurisdictional and cannot be extended for convenience: replacement property must be identified in writing within 45 days of the relinquished-property closing and acquired within 180 days, with both periods running concurrently from the same date.
- Life insurance death benefits are excluded from gross income under IRC §101(a), but a transfer of a policy for valuable consideration destroys that exclusion above the buyer’s basis unless one of the narrow transfer-for-value exceptions applies.
- A policy failing the seven-pay test becomes a modified endowment contract, permanently converting loan and withdrawal taxation from favorable basis-first to LIFO income-first treatment plus a 10% penalty before age 59½ — and MEC status can never be undone.
- For 2026 the health savings account is the only triple-tax-advantaged vehicle in the Code, with $4,400 self-only and $8,750 family contribution limits, and a solo 401(k) generally beats a SEP IRA at moderate income because it permits an elective deferral on top of the employer contribution.
5.8 Like-Kind Exchanges, Insurance Tax Rules & Coordinating Multi-Account Contributions
This section closes three tax-planning topics that live on the official content outline but do not fit neatly into the portfolio, estate, or retirement chapters. Each is heavily tested because each has a hard rule that a well-meaning advisor can break irreversibly.
1. IRC §1031 Like-Kind Exchanges
What Still Qualifies
The Tax Cuts and Jobs Act narrowed §1031 permanently to real property held for productive use in a trade or business or for investment. Personal property exchanges — equipment, aircraft, artwork, collectibles, franchise licenses, and cryptocurrency — no longer qualify at all.
Within real property the "like-kind" standard is remarkably broad: raw land can be exchanged for an apartment building, a strip center for a medical office, a 30-year leasehold for a fee interest. What does not qualify:
- Property held primarily for sale (dealer inventory, a developer's spec homes)
- A personal residence (though §121 offers its own exclusion)
- Partnership interests — expressly excluded by §1031(a)(2), which is why a partner wanting out of a partnership-held property must first execute a "drop and swap" into tenancy-in-common interests, a maneuver with real substance-over-form risk
- Foreign real property exchanged for U.S. real property (U.S. and foreign real property are not like-kind to each other)
The Deadlines Are Absolute
| Deadline | Trigger | Rule |
|---|---|---|
| 45-day identification | Closing of the relinquished property | Written, signed, unambiguous identification delivered to the qualified intermediary |
| 180-day exchange | The same closing date | Replacement must close by the earlier of day 180 or the due date of the return including extensions |
Both clocks start on the same day and run concurrently — day 180 is not 180 days after day 45. Missing either deadline by a single day converts the entire transaction into a fully taxable sale, with no relief provision.
Identification Rules
The taxpayer may identify:
- Three-property rule: up to three properties of any value; or
- 200% rule: any number of properties whose aggregate fair market value does not exceed 200% of the relinquished property's value; or
- 95% rule: any number of properties of any value, provided the taxpayer actually acquires at least 95% of the aggregate identified value.
Boot, Basis, and the Qualified Intermediary
- Boot — cash received or net debt relief — is taxable to the extent of realized gain. A client who trades down in value or reduces mortgage debt recognizes gain on the difference.
- Basis carries over, reduced by boot received and increased by gain recognized and new cash invested. The deferred gain rides along in the low basis.
- Constructive receipt kills the exchange. The taxpayer may never touch the proceeds; a qualified intermediary must hold them under a written exchange agreement.
- Related-party exchanges under §1031(f) require both parties to hold for two years or the deferral is retroactively disallowed.
Swap till you drop. Because §1014 gives heirs a fair-market-value basis at death, a client can chain §1031 exchanges across decades, deferring gain repeatedly, and have the entire deferred gain erased at death. This is one of the few genuinely permanent tax eliminations available on the blueprint.
Delaware Statutory Trusts (DSTs) are the common landing spot for a client who wants §1031 deferral without management responsibility: a DST interest is treated as a direct real property interest under Rev. Rul. 2004-86, so it qualifies as replacement property, but the investor holds a passive, non-controlling, illiquid position.
2. Tax Rules Governing Insurance Strategies
Death Benefit and the Transfer-for-Value Trap
Death proceeds are excluded from gross income under IRC §101(a). But under §101(a)(2), if a policy is transferred for valuable consideration, the exclusion collapses to the transferee's basis plus subsequent premiums — the rest becomes ordinary income. Exceptions preserve the exclusion for transfers to:
- The insured
- A partner of the insured or a partnership in which the insured is a partner
- A corporation in which the insured is a shareholder or officer
Notably absent: transfers to a co-shareholder. This is why cross-purchase buy-sell agreements funded with life insurance create a transfer-for-value problem when an owner departs and the remaining owners buy the departing owner's policies — and why partnership or LLC structures are frequently used instead to fit within the partner exception.
Cash Value Taxation and the MEC Trap
Inside buildup is tax-deferred under §7702. Non-MEC policies allow basis-first withdrawals and generally tax-free policy loans.
A policy fails the seven-pay test of §7702A — becoming a modified endowment contract — when cumulative premiums in the first seven years exceed what would have paid the policy up in seven level annual premiums. Consequences:
- Distributions and loans are taxed LIFO — income first
- A 10% penalty applies before age 59½
- Status is permanent and infects all future exchanges: a §1035 exchange out of a MEC produces another MEC
Because a material change in benefits restarts the seven-pay period, over-funding a policy to maximize cash value is precisely how well-intentioned advisors create MECs.
Other Rules Worth Knowing
- §1035 exchanges permit tax-free exchange of life-to-life, life-to-annuity, and annuity-to-annuity — but never annuity-to-life.
- Non-qualified annuities distribute on a LIFO basis, and there is no step-up in basis at death — the gain is income in respect of a decedent.
- §2042 pulls death proceeds into the gross estate if the insured held incidents of ownership, which drives the ILIT planning in §9.5.
- Private placement life insurance (PPLI) wraps alternative investments inside a §7702-compliant policy, but requires investor-control compliance and adequate diversification under §817(h).
3. Coordinating Contributions Across Accounts (2026 Figures)
Health Savings Accounts — the Only Triple Play
| 2026 HSA Parameter | Self-Only | Family |
|---|---|---|
| Contribution limit | $4,400 | $8,750 |
| Catch-up (age 55+) | $1,000 | $1,000 per spouse |
| HDHP minimum deductible | $1,700 | $3,400 |
| HDHP out-of-pocket maximum | $8,500 | $17,000 |
Deductible going in, tax-free growth, tax-free qualified withdrawals — and no required minimum distributions. The advanced play is to fund the HSA, pay medical costs out of pocket, retain the receipts, and reimburse decades later, using the HSA as a stealth Roth.
Solo 401(k) vs. SEP IRA
Both allow an employer contribution of up to 25% of compensation (roughly 20% of net self-employment income). The decisive difference is that a solo 401(k) also permits a $24,500 elective deferral ($8,000 catch-up at 50+, $11,250 at ages 60–63). At $100,000 of net self-employment income a SEP produces roughly $20,000 of capacity; a solo 401(k) produces roughly $44,500. Only at very high income do the two converge at the §415(c) ceiling of $72,000.
The solo 401(k) carries a second advantage relevant to §12.2: it can accept a reverse rollover of pre-tax IRA balances, clearing the §408(d)(2) pro-rata rule and unlocking clean backdoor Roth contributions. A SEP IRA is itself an IRA and creates pro-rata contamination.
529 Plans
The five-year front-loading election under §529(c)(2)(B) permits $95,000 per donor per beneficiary in 2026 ($190,000 with gift splitting), removing the amount from the estate while retaining the donor's control over the account.
A Defensible Ordering for a High-Income Household
- Employer 401(k) to the full match — an immediate guaranteed return
- HSA to the limit, treated as a retirement account rather than a spending account
- Remaining elective deferral capacity to $24,500, weighing Roth against pre-tax on expected future bracket
- Backdoor Roth IRA — after clearing pre-tax IRA balances into the plan
- Mega-backdoor after-tax 401(k) contributions to the $72,000 §415(c) limit, if the plan permits
- Cash balance plan for the business owner with surplus profit (see §12.1)
- 529 funding, front-loaded when the estate benefit is wanted
- Taxable, tax-managed accounts — direct indexing and asset location per §5.3
A client closes on the sale of a relinquished commercial building on March 1 as part of an intended IRC §1031 exchange. She identifies suitable replacement property in writing on April 10. Her tax return, with extensions, is not due until October 15. By what date must the replacement property close in order to preserve the deferral?
Two equal shareholders of a closely held C-corporation fund a cross-purchase buy-sell agreement, each owning a $5,000,000 policy on the other. A third shareholder is admitted, and to restructure the arrangement the original shareholders sell their existing policies to one another for the cash surrender value. What is the federal income tax consequence when one insured later dies?
A 48-year-old business owner is deciding between a SEP IRA and a solo 401(k) for her consulting practice, which generates $100,000 of net self-employment income. She also plans to make backdoor Roth IRA contributions each year. Which plan should the advisor recommend and why?
