The Permanent $15 Million Exemption: Succession Planning for the Small-Landlord Portfolio

The Cliff That Didn't Happen

For several years, estate planners worked against a deadline. The doubled federal estate tax exemption from the 2017 Tax Cuts and Jobs Act was scheduled to sunset at the end of 2025, dropping from $13.99 million per person to roughly half that — around $7 million — on January 1, 2026. Landlords with appreciating portfolios spent real money on rushed gifting strategies to beat the cliff.

The cliff never arrived. The One Big Beautiful Bill Act, signed July 4, 2025, permanently set the federal estate, gift, and generation-skipping transfer tax exemption at $15 million per individual — $30 million for a married couple using portability — effective January 1, 2026. The amount is indexed for inflation beginning in 2027, and unlike the TCJA provision it carries no sunset date. A future Congress could change it, but there is no scheduled reversion.

The practical consequence is blunt: per IRS data, fewer than 0.2 percent of estates owe any federal estate tax under current exemption levels. If your portfolio is worth a few million dollars, federal estate tax is not your problem and likely never will be. What the permanent exemption actually does is free small landlords to plan around the risks that genuinely apply to them — instead of the tax their attorney warned them about in 2024.

What Still Applies to You

Probate doesn't care about the exemption. A portfolio that passes through probate — multiple properties, multiple entities, a mortgage on each — is an administrative disaster for heirs regardless of tax. A revocable living trust that actually holds the LLC interests (not merely references them) keeps the transfer private, fast, and out of court. The trust is only as good as its funding: LLC membership interests must be assigned into it, and lenders' due-on-transfer provisions should be reviewed before any entity-level move.

The step-up in basis is the real tax event. Under Internal Revenue Code Section 1014, heirs who inherit appreciated property receive a stepped-up basis to fair market value at death. A building bought for $400,000 decades ago, worth $1.4 million today, passes to heirs with a $1.4 million basis — the lifetime of appreciation and all the accumulated depreciation recapture simply vanish. Heirs start depreciating from the new value.

Gifting the same building during your lifetime does the opposite: the recipient takes your carryover basis. If the goal is for the next generation to eventually sell, a lifetime gift of appreciated property can manufacture a six-figure capital gains bill that inheritance would have erased. This is the single most expensive mistake in family real estate transfers, and it has nothing to do with the estate tax.

How the portfolio is titled determines what survives. Real estate held in a standard LLC generally passes the step-up through to heirs via the membership interest. But entity elections matter: practitioners consistently warn that real estate parked in an S-corporation election — or a C-corporation — can forfeit the inside step-up on the property itself. If your CPA set up an S-election years ago for payroll-tax reasons on the management side, confirm which assets sit inside it. What was a clever structure in 2019 can be a basis trap in 2026.

State taxes didn't get the memo. The federal change has no bearing on the twelve states (plus the District of Columbia) that impose their own estate or inheritance taxes, most with far lower exemption thresholds. If you own property in one of those states, your plan must account for their rules separately.

The Question Nobody Puts in the Trust

Tax mechanics aside, the hardest succession problem for a small landlord is human: the next generation may not want the portfolio. A 5-to-20-unit operation is a part-time job disguised as an asset — tenant calls, turnovers, capex decisions, insurance renewals. Heirs who inherit buildings they can't or won't operate face three honest options:

Keep and professionalize. Hand the portfolio to a property manager and convert it into a managed income stream. This works when the numbers support management fees (typically 8–10 percent of rents) and the heirs are comfortable as passive owners. It fails when the portfolio was only profitable because the owner self-managed.

Sell with the step-up. The cleanest exit for uninterested heirs is often to sell shortly after inheriting, when the stepped-up basis makes the sale nearly tax-free. Document the date-of-death fair market value with an appraisal — that number is the foundation of everything that follows.

Transfer gradually, on purpose. Annual gifts within the $19,000-per-recipient exclusion (the 2026 figure) move LLC interests to the next generation slowly, without touching the lifetime exemption. Pair this with a buy-sell or operating agreement that sets valuation method, transfer restrictions, and what happens if a member wants out. The agreement is the document that prevents the family fight; the gifts are just the funding mechanism.

The Fourth-Quarter Checklist

With the exemption question settled, this is a good quarter to do the unglamorous work:

One: Confirm every entity's ownership records are current. Operating agreements, membership ledgers, and assignments should reflect reality today — not the reality of the year the LLC was formed.

Two: Review beneficiary designations and the trust. Bank accounts, insurance policies, retirement accounts — these pass outside the will and the trust. Stale designations from a decade ago are a routine source of litigation.

Three: Check the S-election question with your CPA. If any entity holding real estate carries an S-election, confirm the basis consequences before doing anything else.

Four: Get the date-of-death valuation process in writing. Heirs need an appraisal protocol they can execute under stress. Name the appraiser relationship now; don't leave it to be found later.

Five: Write the operating instructions. Which properties have mortgages with which lenders, where the insurance policies live, who the contractors are, what the renewal calendar looks like. A successor who can't find the insurance agent can't protect the portfolio.

Six: Talk to the heirs. The most sophisticated trust in the world fails if the beneficiaries learn about the portfolio at the reading of the will. Succession is a conversation first and a document set second.

None of this requires urgency — that was the old regime, the one with the deadline. The permanent exemption bought landlords the one thing rushed planning never allowed: time to do it properly.
