100 estate tax questions answered: essential facts for taxpayers and estate planning -

Estate tax is one of those subjects people tend to postpone until a lawyer mentions a deadline. By then, the family may be dealing with grief, paperwork, property valuations and a tax bill—all at once.

The good news is that most estates do not owe federal estate tax. The less comforting news is that estate planning still matters, particularly when a family owns a business, valuable property, investment accounts or assets in more than one country.

Below are 100 practical answers covering the federal estate tax, gift tax, trusts, probate, valuations and planning decisions. The rules can change, and state taxes may apply even when federal tax does not. Treat this as a reliable starting point, not a substitute for personalised legal or tax advice.

Federal estate tax basics

1. What is estate tax? It is a tax on the transfer of certain property after someone dies.
2. Who collects federal estate tax? The Internal Revenue Service collects it under the Internal Revenue Code.
3. Is estate tax the same as inheritance tax? No. Estate tax is charged to the estate; inheritance tax is generally charged to the beneficiary.
4. Do all estates pay federal estate tax? No. Only taxable estates exceeding the applicable federal exemption generally pay.
5. What is the federal estate tax rate? The top rate is 40%, applied progressively to taxable transfers.
6. What is the 2025 federal exemption? The basic exclusion amount is $13.99 million per person for deaths in 2025.
7. Is the exemption permanent? Not necessarily. Congress can change it, so long-term plans require periodic review.
8. Does the exemption cover lifetime gifts? Yes. Lifetime taxable gifts generally reduce the exemption available at death.
9. What is the unified credit? It is the tax credit that shelters transfers within the lifetime gift and estate tax exemption.
10. Does estate tax apply to the whole estate? It applies to the taxable estate, not automatically to every dollar owned.

What counts as part of an estate?

11. Is a home included? Yes, usually at its fair market value on the date of death.
12. Are bank accounts included? Yes, including individual and certain jointly owned accounts.
13. Are retirement accounts included? Yes. Traditional IRAs, 401(k)s and similar accounts are generally part of the gross estate.
14. Are life insurance proceeds included? They may be, especially when the deceased owned the policy or retained control.
15. Are business interests included? Yes. A private company interest must be valued, even if it is difficult to sell.
16. Are vehicles included? Yes, normally at their fair market value.
17. Are personal belongings included? Yes. Jewellery, art, collections and other valuable items count.
18. Are digital assets included? Potentially. Cryptocurrency, online accounts and digital royalties may have estate value.
19. Are debts deducted? Valid mortgages, loans, credit balances and other enforceable debts may reduce the taxable estate.
20. Are funeral expenses deductible? Often, yes, subject to federal rules and proper documentation.

Valuation and the tax calculation

21. How is property valued? Generally by fair market value: what a willing buyer would pay a willing seller.
22. What date is used? Usually the date of death.
23. Can an alternative valuation date be used? In certain cases, an executor may elect a date six months later.
24. Why does valuation matter? A higher value can increase estate tax; a lower value can trigger IRS scrutiny.
25. Is an appraisal always required? Not for every asset, but real estate, businesses, art and unusual property often need professional appraisals.
26. Can a family simply agree on a value? Family agreement does not replace defensible tax documentation.
27. What is a minority-interest discount? It reflects reduced marketability or control in a privately held business interest.
28. Are valuation discounts automatic? No. They require genuine economic support and careful documentation.
29. What happens if property is undervalued? The IRS may assess additional tax, interest and penalties.
30. Should beneficiaries keep valuation records? Yes. They may need them when calculating future capital gains.

Married couples and portability

31. Is property passing to a spouse usually taxed? Transfers to a qualifying US-citizen spouse generally qualify for the unlimited marital deduction.
32. Does that mean tax disappears? No. Tax may be deferred until the surviving spouse dies.
33. What is portability? It allows a surviving spouse to use certain unused exemption from the first spouse.
34. Is portability automatic? No. A timely federal estate tax return is generally required.
35. Which form requests portability? Form 706, United States Estate (and Generation-Skipping Transfer) Tax Return.
36. What is DSUE? It means deceased spousal unused exclusion—the unused exemption transferred to the survivor.
37. Can portability be claimed years later? Sometimes. IRS relief procedures may help, but relying on relief is risky.
38. Does portability work for non-US-citizen spouses? Usually not without a qualifying treaty or special planning structure.
39. Is a bypass trust still useful? It can be, particularly for asset protection, control, remarriage concerns or state tax planning.
40. Should every couple use the same plan? No. Wealth, citizenship, family dynamics and state residence all matter.

Gifts during your lifetime

41. What is a taxable gift? It is generally a transfer for less than full value during life.
42. What is the 2025 annual exclusion? An individual may give $19,000 per recipient in 2025 without using lifetime exemption.
43. Can spouses combine annual exclusions? Yes, with the correct election and reporting.
44. Can you give $19,000 to several people? Yes. The limit applies per recipient, not to all recipients collectively.
45. Are tuition payments gifts? Direct payments to a qualifying educational institution can be excluded.
46. Are medical payments gifts? Direct payments to the medical provider may qualify for an unlimited exclusion.
47. Are birthday presents taxable gifts? Potentially, if their value exceeds available exclusions and other exemptions.
48. Does paying someone’s mortgage count? Usually, unless a specific exclusion or full repayment applies.
49. Must every gift be reported? Not every gift. Taxable gifts and certain split gifts require Form 709.
50. Is a gift tax return the same as paying gift tax? No. Filing may simply document a gift that uses part of your lifetime exemption.

Trusts, wills and probate

51. Does a will avoid estate tax? No. A will directs distribution; it does not automatically reduce tax.
52. Does a trust avoid estate tax? Not automatically. Ownership and retained control determine the tax treatment.
53. What is a revocable living trust? A trust you can generally change or cancel during your lifetime.
54. Does a revocable trust remove assets from your taxable estate? Usually not, because you retain control.
55. What is an irrevocable trust? A trust that generally limits your ability to reclaim or alter transferred assets.
56. Can an irrevocable trust reduce estate tax? Potentially, if properly structured and funded.
57. What is probate? It is the court-supervised process for validating a will and transferring certain assets.
58. Does probate create estate tax? No. Probate and estate tax are separate issues.
59. Can beneficiary designations avoid probate? Often, yes. They do not necessarily avoid estate taxation.
60. What is the biggest trust mistake? Creating a trust but never transferring assets into it—the paperwork equivalent of buying a gym membership and never going.

Life insurance and retirement accounts

61. Does life insurance pass tax-free? Beneficiaries often receive proceeds free of income tax, but estate tax treatment is different.
62. Why might insurance be included in the estate? Ownership, policy control and incidents of ownership can bring proceeds into the gross estate.
63. What is an irrevocable life insurance trust? A specialised trust designed, when correctly administered, to keep insurance outside the insured’s taxable estate.
64. Are retirement accounts taxed at death? They may create income tax for beneficiaries and may also be included in the estate.
65. What is the SECURE Act impact? Many non-spouse beneficiaries must withdraw inherited retirement funds within a limited period, often 10 years.
66. Can a spouse roll over an inherited IRA? Generally, a surviving spouse has rollover options unavailable to many other beneficiaries.
67. Should children inherit a traditional IRA directly? Not always. Tax brackets, timing and estate goals should be reviewed.
68. Are Roth IRAs included in the estate? Yes, although qualified distributions are generally income-tax-free.
69. Do beneficiary forms override a will? Usually, yes. The latest valid designation normally controls.
70. What is the practical lesson? Review beneficiary forms after marriage, divorce, births, deaths and major financial changes.

State estate and inheritance taxes

71. Do states impose estate tax? Yes. Several states and the District of Columbia impose their own estate taxes.
72. Are state exemptions identical to the federal exemption? No. They can be dramatically lower.
73. What is an inheritance tax? It is a state tax based largely on who receives the property.
74. Which states impose inheritance tax? States such as Pennsylvania, Maryland, Kentucky, New Jersey and Nebraska have inheritance taxes, with important exceptions.
75. Can moving states reduce tax? Sometimes, but domicile is based on facts—not just a new driving licence.
76. Can owning property create state filing obligations? Yes, especially real estate located in another state.
77. Does a vacation home matter? It can create estate, probate and state filing issues.
78. Do states recognise portability? Some do, some limit it and some do not.
79. Are state rules updated regularly? Yes. Exemptions, rates and filing thresholds can change.
80. What should multi-state families do? Ask counsel to map assets, residence, property location and beneficiary residence.

Non-US citizens and international families

81. Are non-US citizens subject to US estate tax? They may be, particularly on US-situs assets.
82. Is the exemption the same for nonresident noncitizens? No. The standard federal threshold can be as low as $60,000 of US-situs assets.
83. What are US-situs assets? They can include US real estate, US shares and certain business interests.
84. Can a tax treaty help? Yes. Treaties may modify exemptions, classifications or filing obligations.
85. Is a foreign bank account US-situs property? Usually not merely because a US person owns it, but reporting rules may still apply.
86. Are foreign estates always outside US tax? No. Citizenship, residence, asset location and treaty rules must be analysed.
87. Can a noncitizen spouse receive assets tax-free? Not always. A qualified domestic trust, or QDOT, may be needed.
88. What is a QDOT? It is a trust that can preserve marital deduction treatment for a qualifying noncitizen spouse.
89. Does foreign property need valuation? Yes. Its value and location can affect reporting and tax calculations.
90. What is the safest international strategy? Coordinate US advisers with qualified counsel in every relevant country.

Filing, payment and practical planning

91. Who files Form 706? The executor or personal representative generally files it.
92. When is Form 706 due? Generally nine months after death.
93. Can the filing deadline be extended? A six-month filing extension is generally available with Form 4768.
94. Does an extension delay payment? Usually not. Interest may apply to unpaid tax after the original due date.
95. What if the estate lacks cash? Options may include asset sales, borrowing, life insurance or eligible instalment payment rules.
96. Can a closely held business pay in instalments? Section 6166 may allow qualifying estates to spread payments over time.
97. What is the basis of inherited property? It is generally adjusted to fair market value at death, often called a step-up in basis.
98. Does a step-up eliminate all capital gains? No. It resets basis but does not erase gains after the valuation date.
99. What documents should families organise now? Wills, trusts, deeds, account statements, insurance, business records and beneficiary forms.
100. What is the most useful first step? Build a complete asset list, identify ownership and beneficiaries, then obtain advice before transferring anything.

A practical estate-planning checklist

Start with the facts rather than the fashionable solution. List every asset, its owner, approximate value, location and beneficiary. Then identify debts, insurance, business interests and previous lifetime gifts.

Next, check whether your plan works in the state where you live and in any state where you own property. A federal exemption that looks generous on paper does not automatically solve a state-level tax problem.

Finally, review the plan after major events: marriage, divorce, a new child, inheritance, business sale, relocation or a serious change in wealth. Estate planning is not a document you sign once and file beside the spare batteries. It is a system that needs maintenance.

The objective is straightforward: ensure the right people receive the right assets, at the right time, with as little avoidable tax, delay and conflict as possible.
