The federal estate tax system is separate from the income tax system and also differs from state-level estate and inheritance taxes. Estate planning can involve wills, trusts, beneficiary designations, lifetime gifts, and other arrangements designed to organize how assets are transferred.

The taxable estate generally starts with the value of property and financial interests included in the estate. Certain deductions, exclusions, and adjustments can affect the amount ultimately subject to federal estate tax.

Common estate-planning components include:

• Wills and testamentary documents

• Revocable and irrevocable trusts

• Beneficiary designations

• Lifetime gifts

• Charitable transfers

• Marital transfers

• Business interests

• Real estate

• Investment accounts

• Life insurance considerations

The rules can become complex when an estate includes substantial investments, businesses, real estate, trusts, or assets transferred during the individual's lifetime.

Importance

Understanding estate tax matters most for individuals and families whose assets may approach or exceed applicable federal or state thresholds. Estate planning can also matter for people who want to understand how property, investments, businesses, and other assets may pass to beneficiaries.

For 2026, the federal basic exclusion amount is $15 million per individual, following changes made by the One Big Beautiful Bill Act enacted in 2025. The IRS explains that the exclusion amount is indexed for inflation after 2026. (irs.gov)

The federal estate tax rate can reach 40% on the taxable estate above the applicable exclusion amount. However, the tax is not simply calculated by applying 40% to everything a person owned. The federal estate tax calculation involves determining the gross estate, applicable deductions, taxable gifts, credits, and other factors. (irs.gov)

Important estate-planning considerations include:

Estate planning is therefore broader than simply minimizing taxes. It can also involve administration, asset management, family objectives, charitable intentions, and succession planning.

Recent Updates

The most significant recent federal estate-tax development occurred in 2025, when the One Big Beautiful Bill Act changed the federal estate and gift tax exclusion.

The IRS states that the basic exclusion amount increased from $13.99 million in 2025 to $15 million in 2026. The annual exclusion for gifts also increased from $19,000 in 2025 to $19,000 in 2026, with the annual gift-tax exclusion generally indexed for inflation. (irs.gov)

The legislation also made the increased estate and gift tax exemption permanent rather than allowing the prior scheduled reduction to take effect after 2025. (congress.gov)

Another important concept is portability. Under applicable federal rules, a surviving spouse may potentially use the deceased spouse's unused exclusion amount if the required estate tax return is timely filed and the election is properly made.

The IRS also updated its estate and gift tax materials for the 2026 tax year, including the applicable exclusion amounts and filing information. (irs.gov)

These changes make current-year estate planning particularly important for families with substantial assets because federal thresholds and planning assumptions that applied several years ago may no longer be accurate.

Laws or Policies

Federal estate tax is administered by the Internal Revenue Service (IRS) under the Internal Revenue Code. Form 706, United States Estate (and Generation-Skipping Transfer) Tax Return, is generally used to report an estate subject to federal estate tax and for certain other purposes, including making a portability election. (irs.gov)

For estates of U.S. citizens or residents, Form 706 is generally required when the gross estate plus certain adjusted taxable gifts exceeds the applicable exclusion amount for the year of death, subject to the rules and exceptions in the instructions.

The federal gift tax system is connected to estate tax planning. Lifetime taxable gifts can affect the calculation of the unified estate and gift tax system, while the annual gift tax exclusion can allow qualifying gifts up to the annual exclusion amount without using the lifetime basic exclusion.

The generation-skipping transfer (GST) tax is another federal transfer tax that can apply to certain transfers benefiting people who are two or more generations below the transferor, such as grandchildren. GST planning can therefore become relevant in certain family trust and inheritance structures.

State laws are separate. Some states impose estate taxes, inheritance taxes, or both, and their thresholds can differ substantially from federal rules. A person can therefore have state-level estate-tax considerations even when federal estate tax does not apply.

Because estate-tax laws are detailed and can change, taxpayers should use current IRS guidance and qualified tax or legal professionals when making decisions involving significant assets.

Tools and Resources

Several official resources can help with estate-tax research and planning.

IRS Estate Tax resources: The IRS provides information about federal estate-tax rules, exclusion amounts, filing requirements, deductions, and related topics. (irs.gov)

Form 706: This is the principal federal estate tax return used for applicable estates. Its instructions explain valuation, deductions, credits, portability, and filing requirements. (irs.gov)

Gift tax resources: IRS materials explain annual gift exclusions, taxable gifts, Form 709, and how gift-tax rules interact with estate planning. (irs.gov)

Estate inventory worksheet: A structured inventory can organize real estate, bank accounts, investments, business interests, insurance policies, personal property, debts, and other relevant information.

Beneficiary review: Retirement accounts, insurance policies, and financial accounts should be reviewed periodically to ensure beneficiary information reflects the individual's intentions.

Useful planning records can include:

• Asset inventories

• Property valuations

• Trust documents

• Will and estate documents

• Beneficiary designations

• Gift records

• Business ownership records

• Insurance documentation

• Debt information

FAQs

What is the federal estate tax exemption for 2026?

For 2026, the federal basic exclusion amount is $15 million per individual. The amount is subject to applicable federal rules and future inflation adjustments. (irs.gov)

Does everyone have to pay federal estate tax?

No. Federal estate tax applies only when the applicable requirements are met. The calculation considers the gross estate, deductions, taxable gifts, exclusions, and other factors. Many estates do not owe federal estate tax.

What is the difference between estate tax and inheritance tax?

Estate tax is generally imposed on the transfer of property from a deceased person's estate, while an inheritance tax is generally imposed on the person receiving inherited property. Federal law has an estate tax, while certain states impose inheritance taxes.

How can a trust affect estate planning?

Different types of trusts have different legal and tax consequences. A revocable living trust, for example, is commonly used for estate administration and asset management, while certain irrevocable trusts can have different estate-tax implications. The effect depends on the trust terms and applicable law.

What is estate tax portability?

Portability can allow a surviving spouse to use certain unused federal estate-tax exclusion from a deceased spouse. The required estate tax return and election must generally be completed according to IRS requirements and deadlines. (irs.gov)

Conclusion

Estate tax planning involves understanding federal transfer-tax rules, applicable exemptions, asset ownership, lifetime gifts, trusts, beneficiary designations, and state-level requirements.

For 2026, the federal basic exclusion amount is $15 million per individual, making the current federal threshold substantially higher than in earlier years. The 2025 legislation that established the higher threshold also changed the long-term federal estate-planning landscape. (irs.gov)

However, estate planning should not focus solely on the federal exemption. State taxes, family circumstances, business interests, charitable goals, asset ownership, and potential changes in tax law can all affect an estate plan.

Keeping accurate asset records, reviewing beneficiary designations, understanding existing trusts, and maintaining current legal and tax documents can help families organize their financial affairs. For substantial or complex estates, individualized advice from qualified estate-planning attorneys and tax professionals is appropriate.
