Understanding Federal Estate Tax Basics

Federal estate tax is a tax applied to the transfer of property from a deceased person to their heirs. When someone passes away, the total value of everything they owned—their estate—may be subject to federal taxation. The federal government has set a threshold, called the exemption amount, below which most estates do not owe federal estate tax. As of 2024, this exemption is $13.61 million per person. This means an estate valued below this amount typically does not trigger federal estate tax obligations.

It is important to understand that federal estate tax is separate from income tax, property tax, and state estate taxes. Each operates under different rules and thresholds. Some states impose their own estate taxes with much lower exemption amounts than the federal level. For example, New York's state estate tax exemption is $6.94 million, meaning estates above that amount may owe state taxes even if they do not owe federal taxes.

The federal exemption amount is not permanent. Under current law, it is scheduled to drop to approximately $7 million per person (adjusted for inflation) on January 1, 2026. This sunset provision means families with substantial estates should understand how their situation may change. An estate worth $10 million might not owe federal taxes in 2024 but could face significant tax liability in 2026 if no planning steps are taken.

Federal estate tax rates, when applicable, are steep—currently at 40 percent of the amount exceeding the exemption. This means understanding the tax's basic mechanics is crucial for anyone with a substantial estate. An informational guide on federal estate tax can explain these foundational concepts, including how the government calculates estate value, what property is included, and how exemptions work.

Practical takeaway: Review the current federal exemption amount and compare it to your estimated net worth. This simple comparison reveals whether your estate might face federal tax obligations under current or future law.

What Property Is Included in Your Taxable Estate

The taxable estate includes far more than just a house and bank accounts. The Internal Revenue Service (IRS) includes most property owned at death, regardless of how title is held. This encompasses real estate, vehicles, bank accounts, retirement accounts, investment portfolios, business interests, life insurance proceeds, and personal property like jewelry and art collections. Many people are surprised to learn that life insurance death benefits—money paid to beneficiaries—count toward the taxable estate if the deceased owned the policy.

Property held jointly with others is included in full value if spouses own it together, though only half typically counts for the deceased spouse's estate. If two non-spouse co-owners hold property jointly, the entire value usually counts in the deceased owner's estate unless they can prove the other owner contributed to the purchase. Retirement accounts like 401(k)s and IRAs pass to named beneficiaries outside the probate process, but their value still counts in the taxable estate for federal tax purposes.

Some property is excluded from the taxable estate. Life insurance proceeds are exempt if owned by someone other than the deceased—for example, if adult children own a policy on a parent's life. Charitable donations made at death are deductible. Property passing to a surviving spouse through the "unlimited marital deduction" generally avoids federal estate tax, though the exemption still applies to the surviving spouse's own property later.

The valuation date matters significantly. Property is typically valued as of the date of death, though executors may elect to value it six months later if that value is lower. A house worth $500,000 at death, a brokerage account with $2 million, a vacation property worth $1.5 million, and retirement accounts totaling $1.2 million quickly accumulate to a $5.2 million estate—well above many people's expectations and closer to current federal exemption thresholds for larger estates or near the future $7 million threshold.

Practical takeaway: Create a detailed inventory of all property you own, including real estate, financial accounts, retirement funds, business interests, and life insurance policies. Include estimated current values. This inventory reveals the true size of your estate and whether federal tax planning may be relevant.

How the Federal Exemption Works and Recent Changes

The federal estate tax exemption is a fixed dollar amount that represents the threshold below which federal estate tax does not apply. Think of it as a tax-free allowance. Currently set at $13.61 million per individual, this exemption means a single person can pass $13.61 million to heirs without owing any federal estate tax. A married couple can combine their exemptions to $27.22 million, provided they use proper planning strategies.

The exemption has changed significantly over the past two decades. In 2001, it was just $675,000. The George W. Bush administration increased it gradually, reaching $3.5 million by 2009. The Obama administration established it at $5 million in 2010, adjusted for inflation each year. The Tax Cuts and Jobs Act of 2017 doubled the exemption, raising it to approximately $10 million per person (adjusted for inflation), where it has remained through 2024. This temporary increase was politically contentious and was always scheduled to expire.

The scheduled sunset on January 1, 2026, represents a dramatic change. Unless Congress acts, the exemption will drop to the 2009 level of approximately $7 million per person (adjusted for inflation). For a married couple, this means the combined exemption could drop from $27.22 million to roughly $14 million. Estates between the new and old thresholds would suddenly owe federal tax. An estate worth $20 million might owe no tax in 2024 but could face $5.2 million in federal taxes after 2025 (assuming 40 percent rates on the amount over the new exemption).

Some families with large estates have begun "exemption portability" planning and other strategies to lock in current exemption amounts before 2026. This involves filing gift tax returns and using exemptions strategically before the sunset occurs. Federal estate tax information guides explain how the exemption applies, recent changes, and the importance of understanding timing for anyone with substantial assets.

Practical takeaway: Mark January 1, 2026, on your calendar. If your estate is between $7 million and $13.61 million in value, consult with an estate planning attorney or financial professional about potential planning options before the exemption decreases, as current rules may change and planning decisions may become time-sensitive.

Who Actually Pays Federal Estate Tax Today

Despite widespread awareness of federal estate tax, relatively few estates actually owe it. According to IRS data, in 2022, only approximately 3,500 estates filed estate tax returns, and fewer than 2,500 paid any federal estate tax. This represents less than 0.1 percent of all estates. The high exemption amount means that the vast majority of Americans—even those with substantial assets—will never owe federal estate tax.

The estates that do pay federal tax tend to be quite large. The median estate that owes federal tax exceeds $25 million. These typically include significant business interests, real estate portfolios, investment accounts, and family business succession issues. High-net-worth individuals, business owners, and families with substantial accumulated wealth are the primary groups affected by current federal estate tax rules.

State estate taxes affect more people than federal taxes, however. Approximately 17 states and Washington D.C. impose estate or inheritance taxes with much lower exemptions. New York's exemption is $6.94 million, New Jersey's is $5.49 million, and Massachusetts has no exemption—estates of any size may owe state tax. For residents of these states, even moderate wealth can trigger state-level estate tax obligations. A business owner with a $10 million estate in New Jersey would owe no federal tax but could face significant New Jersey state estate taxes.

Understanding whether federal estate tax is likely to affect an estate involves calculating its total value and comparing it to current and projected exemption amounts. Families with estates below $13.61 million under current law may still benefit from understanding federal tax rules, particularly if they live in states with lower exemptions or if their estate is likely to grow substantially. An informational guide on federal estate tax provides data on how many estates are affected and the characteristics of those that are.

Practical takeaway: Research your state's estate tax rules. Even if federal estate tax is unlikely, state-level taxes could apply to
