SC Estate Tax Exemption Now $15M: What Families Need to Know

What Happened

Congress permanently raised the federal estate and gift tax exemption to $15,000,00026 USC 2001(c), 2010; P.L. 119-21 §70106Verified Jul 13, 2026View source per individual, effective January 1, 2026. For married couples, the combined exemption reaches $30,000,00026 USC 2001(c), 2010; P.L. 119-21 §70106Verified Jul 13, 2026View source. The change came through the One Big Beautiful Bill Act, signed into law in July 2025.

For years, estate planning attorneys across South Carolina and the rest of the country warned clients about a looming deadline. The Tax Cuts and Jobs Act of 2017 had temporarily doubled the federal exemption, but that increase carried a built-in expiration date at the end of 2025. Families with substantial assets spent years restructuring plans to avoid a projected drop back to roughly half the current level. That countdown ended when Congress acted to make the higher exemption permanent, with future adjustments tied to inflation.

The change affects how families approach federal estate tax planning going forward. At $15,000,00026 USC 2001(c), 2010; P.L. 119-21 §70106Verified Jul 13, 2026View source per person, the overwhelming majority of South Carolina households sit well below the threshold, even when accounting for a home that appreciated significantly, a retirement account built over decades, or a small business. South Carolina imposes no state estate tax and no inheritance tax, so residents face only the federal levy if their taxable estate exceeds the exemption at death. The planning question has shifted from how to get under a falling threshold to whether existing documents still accomplish what their creators intended under the new numbers.

What It Means

The permanent exemption increase removes a pressing concern for most South Carolina families, but it introduces a different kind of planning risk. Many estate plans drafted before 2026 contain formula clauses that direct assets up to a specific dollar amount to one set of beneficiaries, with the remainder passing elsewhere. When the exemption was lower, those formulas produced predictable results. Now that the number has nearly doubled, the same language can redirect far more wealth than the document's creator ever intended. A surviving spouse, children from a prior relationship, or a charitable remainder could each receive a very different share than the plan originally contemplated.

Portability remains one of the most consequential planning tools for married couples, and one of the most commonly overlooked. When the first spouse dies, the executor can elect to preserve the deceased spouse's unused exemption for the surviving spouse's benefit. At current levels, that election can protect up to $15,000,00026 USC 2001(c), 2010; P.L. 119-21 §70106Verified Jul 13, 2026View source in additional assets from federal estate tax when the second spouse dies. The election requires filing a federal estate tax return within nine months of death, with possible extensions, even when no tax is owed. Missing that deadline can permanently eliminate a benefit that costs nothing to claim. Families who lost a spouse in recent years and never filed the return may have lost this protection without realizing it.

Annual gifting continues to offer a straightforward path for transferring wealth across generations. In 2026, an individual can give up to $19,00026 USC § 2503(b); Rev. Proc. 2025-32 § 4.42Verified Jul 13, 2026View source per recipient without filing a gift tax return or drawing on the lifetime exemption. Married couples can combine exclusions to give $38,000 per recipient. Gifts within the annual exclusion also remove future growth from the taxable estate. Larger gifts draw on the same $15,000,00026 USC 2001(c), 2010; P.L. 119-21 §70106Verified Jul 13, 2026View source lifetime exemption that applies at death, since the gift and estate tax systems share a unified structure. For families with estates approaching the threshold, the timing and structure of larger gifts carries real consequences. Because South Carolina levies no state-level gift or estate tax, families here face only federal rules when evaluating gifting strategies. Readers exploring how estate values are calculated can review the Glossary of Basic Estate Planning Terms for a plain-language breakdown of gross estate, net estate, and taxable estate concepts.

Irrevocable trusts serve purposes that extend well beyond federal estate tax reduction. An irrevocable trust removes assets from the grantor's taxable estate because the grantor surrenders direct ownership and control. Depending on the structure, those assets can gain protection from creditors, support a beneficiary's long-term care without affecting Medicaid eligibility, or provide liquidity for illiquid assets like closely held businesses or appreciated real estate. Irrevocable life insurance trusts, known as ILITs, allow a trust rather than the insured to own a life insurance policy. When properly structured, this arrangement removes the death benefit from the insured's taxable estate and makes proceeds available for estate costs or business obligations without forcing the sale of family assets. The tradeoff is permanence: once established, an irrevocable trust cannot be easily undone. A revocable living trust, by contrast, keeps assets in the taxable estate because the grantor retains control, but it still delivers meaningful benefits: probate avoidance, privacy, and continuity of management during incapacity.

Charitable giving strategies offer a dual benefit for families with causes they support. Assets passing to a qualifying nonprofit organization are excluded from the taxable estate. A Charitable Remainder Trust allows a donor to transfer appreciated assets into a trust, receive an income stream during life, and direct the remainder to charity at death. This structure can help families holding concentrated positions in real estate or low-basis stock diversify without triggering an immediate capital gains tax event.

Code Ann. § 12-6-1150 (44% net capital gain deduction)Verified Jul 13, 2026View source from state tax, which affects how families here calculate the net cost of selling appreciated assets outside a charitable structure. A Donor-Advised Fund offers a simpler alternative: a donor contributes assets, claims an immediate deduction, and recommends grants to charities over time without the administrative requirements of a formal trust.

Context from SimplyTrust

The permanent exemption increase gives most South Carolina families more breathing room at the federal level, but it does not eliminate the value of a careful document review. Plans drafted before 2026 may contain language that now produces unintended results. Married couples face real deadlines around portability that exist regardless of where the exemption sits. And families with irrevocable trusts, ILITs, or formula-based distributions benefit from confirming that existing structures still align with current goals. The What Is Probate? guide explains how assets move through the estate settlement process and why document structure matters at every stage.
