Estate Tax Planning Basics — What Every Family Needs to Know Before It's Too Late

The estate tax isn't about death. It's about timing. And most families get the timing wrong — usually because they wait until the wrong moment to start planning, or assume the exemption is high enough that it won't ever matter to them.

Here's the problem: the rules are changing. The current federal estate tax exemption of $13.61 million per person — or $27.22 million for a married couple — is set to be cut roughly in half when the Tax Cuts and Jobs Act provisions sunset. Unless Congress acts, that happens automatically at the end of 2025. That means a couple with $15 million in combined assets could go from owing zero in estate taxes to owing millions. Not because their wealth changed. Because the law did.

Understanding the basics now gives you options. Waiting until later takes most of them away.

How the Federal Estate Tax Actually Works

The federal estate tax applies to the total value of everything you own at death — real estate, business interests, investment accounts, retirement accounts, life insurance proceeds (if the policy is in your name), farm and ranch land, everything. The value above your exemption is taxed at a top rate of 40%.

So if you're a single individual with $16 million in assets and die in 2026 under the reduced exemption of roughly $7 million, roughly $9 million would be subject to estate tax. At 40%, that's a $3.6 million bill — due within nine months of death, largely in cash.

For farmers, ranchers, and business owners, this is especially brutal because most of your wealth is illiquid. You can't write a check out of a section of pasture.

Portability — The Tool Most Couples Don't Use

When one spouse dies, their unused estate tax exemption doesn't have to disappear. The surviving spouse can "port" the deceased spouse's remaining exemption to their own estate — effectively stacking both exemptions. This is called the portability election, and it must be claimed by filing a timely estate tax return (Form 706) within nine months of death, even if no estate tax is owed.

Skipping this step is one of the most common — and most expensive — estate planning mistakes. A couple where the first spouse dies with $5 million in assets and a $13.61M exemption has $8.61M of unused exemption. Without the portability election, that's gone. With it, the surviving spouse has $22+ million of combined coverage.

Basic Estate Tax Planning Steps Every Family Should Take

You don't need to be wealthy to need a plan. But the higher your net worth, the more urgently these steps matter:

• Get a current estate valuation. You can't plan around a number you don't know. This means appraising real estate, business interests, and investment accounts — not guessing.
• Use the annual gift tax exclusion. In 2026, you can give up to $18,000 per recipient per year completely tax-free. A couple can give $36,000 per year to each child. Over 10 years, that's real money moved out of your taxable estate.
• Consider irrevocable life insurance trusts (ILITs). Life insurance proceeds paid to your estate are counted in your taxable estate. A properly structured ILIT keeps those proceeds out of the estate while still providing liquidity to pay any taxes owed.
• Review beneficiary designations. Assets like IRAs, 401(k)s, and life insurance pass outside of your will. Outdated beneficiary designations can blow up the best estate plan.
• Talk to an estate planning attorney and your CPA now — before 2025 expires. The strategies available before the sunset are different from what's available after.

Why Landowners and Business Owners Face a Unique Challenge

Ranch land, farmland, and business interests create a specific estate planning problem: the value is high, but the cash isn't there. A 1,500-acre operation in the Texas Panhandle might appraise at $5–10 million, but that doesn't mean the family has $2–4 million liquid to pay an estate tax bill.

There are tools designed for this — Section 6166 installment payments for closely held businesses, special use valuation under Section 2032A for qualifying farm and ranch land, and strategic life insurance policies that provide estate liquidity. But none of them work if you haven't set them up in advance.

Consult a qualified estate planning attorney and CPA for strategies specific to your situation. The laws and thresholds shift frequently, and what's correct today may be different by the time you need to act.
