Form 706

Form 706 is a critical IRS document officially titled “United States Estate (and Generation-Skipping Transfer) Tax Return.” It serves to report the assets and calculate federal estate taxes levied on the transfer of wealth from a deceased individual to heirs or beneficiaries. Since federal estate tax applies only when an estate exceeds a set exemption amount, Form 706 is mostly filed for larger estates, though rules require filing in certain other scenarios.

Purpose and Scope of Form 706

The form captures the total gross estate’s value, including cash, real estate, stocks, business holdings, and sometimes life insurance proceeds if payable to the estate, to determine if estate taxes apply. It also accounts for debts, funeral expenses, and deductible transfers to identify the taxable estate portion. Additionally, Form 706 incorporates reporting for generation-skipping transfer (GST) taxes, which target transfers skipping a generation, such as assets passing from grandparents directly to grandchildren.

Filing Requirements and Deadlines

Executors, administrators, or personal representatives must file Form 706 within nine months following the date of the decedent’s death. If more time is needed, a six-month extension can be requested, though any estimated tax owed should be paid to avoid penalties. Filing deadlines and requirements are rigorously enforced by the IRS, with penalties for late submission and nonpayment of taxes.

The crucial filing trigger is whether the deceased person’s gross estate combined with adjusted taxable gifts exceeds the federal estate tax exemption. For example, the exemption amount was $12.92 million in 2023 but routinely adjusts annually for inflation. Even if no estate tax is owed, filing might still be necessary, particularly to elect portability of the unused estate tax exemption for a surviving spouse.

Key Aspects of the Estate Valuation

The valuation of the estate includes all assets owned by the decedent at death, such as:

• Real estate properties
• Bank accounts and cash
• Stocks, bonds, and investment funds
• Business interests including partnerships and corporations
• Life insurance policies payable to the estate

Debts, mortgages, funeral costs, and certain transfers can reduce the taxable estate value. Proper valuation is critical and often involves appraisals or professional assessments.

Importance of Portability Election

One important option available when filing Form 706 is electing portability. This allows the surviving spouse to use any unused federal estate tax exemption from the deceased spouse’s estate. Portability must be elected on Form 706; it is not automatic. To learn more, see our detailed article on What is Portability of the Estate Tax Exemption?.

Real-World Example

Consider an estate worth $12 million including a home, stocks, and retirement accounts. The 2023 exemption threshold was $12.92 million, so no tax might be owed. However, filing Form 706 can still be required, especially if the estate plans to elect portability or has made previous taxable gifts.

Common Misconceptions and Mistakes

• Only the super-wealthy file Form 706: Exemption thresholds change, so some estates must file even if no tax is owed.
• Portability is automatic: Executors must file Form 706 to claim this benefit.
• Deadline negligence: Missing the nine-month filing deadline without an extension can lead to significant penalties.

Tips for Filing Form 706

• Begin collecting and organizing estate documents promptly after death.
• Work closely with estate attorneys or CPAs experienced in estate and tax laws.
• Request a timely extension if additional time is needed to prepare, and estimate taxes to avoid penalties.

Filing Method and State Taxes

Currently, Form 706 must be filed by paper mail to the IRS; electronic filing is not available. Federal estate tax is separate from state estate or inheritance taxes. Each state administers its own forms and rules, so estate administrators should check requirements in their state.
