- Allows portability of unused spousal exclusion.
What is Form 706?
Form 706 is the United States Estate (and Generation-Skipping Transfer) Tax Return filed by the executor of an estate when the decedent's gross estate exceeds the federal exemption threshold. This form reports the fair market value of all worldwide assets, including real estate, stocks, and businesses, to determine estate tax liability.
Filing Form 706 is mandatory for U.S. citizens or residents whose estate plus adjusted taxable gifts surpass the exclusion amount, allowing the IRS to assess the estate tax and generation-skipping transfer tax if applicable.
Key Characteristics
Form 706 captures essential information to calculate estate tax and ensure compliance. Key features include:
- Gross Estate Reporting: Includes all assets valued at fair market value on the date of death, such as real estate, investments, and digital assets.
- Filing Threshold: Required if the estate plus taxable gifts exceed the federal basic exclusion (e.g., $13.61 million in 2024).
- Executor Responsibility: The executor or appointed fiduciary must file the return within nine months of death.
- Portability Election: Allows surviving spouses to claim the deceased spouse's unused exclusion, even if no tax is due.
- Generation-Skipping Transfer Tax: Form 706 calculates GST tax liabilities when assets skip a generation.
How It Works
The executor evaluates all assets owned by the decedent at death, including investments, real estate, and business interests, by obtaining appraisals or market valuations. These values determine the gross estate, which forms the basis for tax calculation.
After reporting the gross estate, allowable deductions such as debts, expenses, and charitable contributions are subtracted. Credits and exemptions are then applied to compute the net estate tax due. Executors may also file an extension using Form 4768 but must pay any tax owed by the original deadline.
Examples and Use Cases
Form 706 applies in various estate planning and administration scenarios, including:
- Business Owners: Executors of estates holding significant interests in companies like Delta must appraise business value accurately for tax reporting.
- High-Net-Worth Individuals: Estates exceeding the exemption threshold, with diversified holdings including stocks, bonds, and real estate, require Form 706 to report assets comprehensively.
- Portability Elections: Spouses can file Form 706 to transfer unused estate tax exclusion amounts, facilitating future tax planning.
- Investment Portfolios: Estates including assets such as dividend stocks or bond ETFs may need to value these holdings precisely, linking to guides on best dividend stocks and best bond ETFs for valuation references.
Important Considerations
Filing Form 706 requires careful asset valuation and understanding of tax rules to avoid penalties. Executors should coordinate with appraisers and tax professionals to ensure accuracy, especially for complex holdings like businesses or intangible assets.
Keep in mind that while the form is due nine months after death, payment of any estate tax is also required by this deadline, even if an extension to file is granted. Understanding your ability to pay taxation can guide appropriate planning and cash flow management for estate settlement.
Final Words
Form 706 must be filed if the estate’s value exceeds the federal exemption or to elect portability for a surviving spouse, even when no tax is due. Review your estate’s valuation carefully and consult a tax professional to ensure timely and accurate filing.
Frequently Asked Questions
IRS Form 706 is the United States Estate (and Generation-Skipping Transfer) Tax Return, required to be filed by the executor of a U.S. citizen or resident's estate if the combined value of the decedent's worldwide gross estate and adjusted taxable gifts exceeds the federal estate tax exclusion amount, which is $13.61 million in 2024. Even if no tax is due, filing is mandatory once this threshold is met.
The executor of the estate, or any person legally liable for filing such as administrators or co-executors, must file Form 706 for estates of U.S. citizens or residents that meet the filing threshold. For nonresidents who are not U.S. citizens, Form 706-NA is used if U.S.-situs assets exceed $60,000.
Yes, estates below the filing threshold can voluntarily file Form 706 to elect portability of the deceased spouse’s unused exclusion (DSUE) to the surviving spouse. This election can be made up to five years after the date of death for qualifying estates under Revenue Procedure 2022-32.
The gross estate includes the fair market value of all assets owned at the date of death, such as real estate, stocks, bonds, businesses, bank accounts, investments, retirement accounts, life insurance, and digital assets. It also includes general powers of appointment and community property interests.
Form 706 allows for deductions such as marital and charitable deductions, debts, and estate administration expenses. It also includes credits like the unified credit against estate tax and foreign death tax credits, which help reduce the overall estate tax liability.
Before filing, the executor should obtain an estate EIN, gather date-of-death valuations or appraisals for assets like real estate and businesses, list lifetime gifts exceeding annual exclusions, review beneficiary designations, insurance policies, retirement accounts, and coordinate with the decedent’s final income tax return (Form 1040).
If multiple persons are liable, they can file one joint return or separate returns disclosing all known estate information. This ensures that all estate assets and tax responsibilities are properly reported and accounted for.
While Form 706 is a federal return, some states have their own estate tax filing requirements. For example, Minnesota requires filing Form M706 for estates valued over $3 million, so it’s important to check state-specific rules alongside federal obligations.
