CFP Estate Planning Cheat Sheet (2026): Key Formulas, Rules, and Mnemonics

You're likely here because you know that Estate Planning (CFP8) on the CFP exam isn't just about memorizing rules; it's about understanding the intricate dance between gift taxes, estate taxes, and income tax basis. The biggest trap candidates fall into? Treating each concept in isolation. They'll nail the annual gift exclusion but completely miss how prior taxable gifts impact the unified credit available at death, leading to a drastically incorrect estate tax calculation.

Estate Planning (CFP8) on the CFP exam tests your ability to apply complex tax laws, gifting strategies, and wealth transfer mechanisms. It requires a deep understanding of how assets are titled, valued, and ultimately distributed, ensuring you can guide clients through minimizing transfer taxes while achieving their legacy goals.

Estate Planning at a Glance

CFP Board's Principal Knowledge Topic 8, Estate Planning, is a high-stakes section, typically accounting for 10-17% of the exam questions. This means you'll face a significant number of problems covering everything from basic wills to complex trust structures and sophisticated tax calculations.

The section tests your understanding across several key domains:

• Wills and Trusts: Differentiating types, identifying key provisions, and understanding their legal implications.
• Gifting Strategies: Annual exclusion, qualified transfers, split gifts, and how taxable gifts reduce the lifetime exemption.
• Estate Tax Calculation: Gross estate, deductions, prior taxable gifts, tentative tax, and unified credit application.
• Generation-Skipping Transfer (GST) Tax: Identifying GSTT events and understanding its application alongside gift and estate taxes.
• Property Titling: How various forms of ownership (e.g., JTWROS, Tenancy in Common, Tenancy by the Entirety) affect probate, basis, and transferability.
• Business Succession Planning: Buy-sell agreements, valuation methods, and strategies for transferring ownership.
• Post-Mortem Planning: Alternate valuation date, disclaimers, and elections.

You'll need to memorize specific thresholds (like annual exclusions and lifetime exemptions), key definitions (e.g., Crummey power, ascertainable standard), and the step-by-step process for calculating estate tax. However, the true path to success lies in understanding the why behind these rules and how they interact. For instance, knowing the annual gift exclusion is $18,000 (for 2024) isn't enough; you need to understand when it applies, who pays the tax if it doesn't, and how it doesn't reduce the donor's lifetime exemption.

Don't just collect facts. Focus on the decision-making framework and the practical implications for clients. For a solid foundation, make sure you're familiar with the general principles of financial planning covered in CFP2; these often underpin ethical and practical estate planning considerations.

Must-Know Formulas, Rules, and Frameworks

Estate planning is calculation-heavy. You must know the sequence and components of the unified transfer tax system cold.

Core Estate Tax Calculation Framework

Here's the essential roadmap for calculating federal estate tax:

• Calculate the Gross Estate: All assets owned or controlled by the decedent at death. This includes probate assets (e.g., solely owned real estate, bank accounts, personal property) and non-probate assets (e.g., JTWROS property, life insurance proceeds where decedent was owner, retirement accounts with named beneficiaries, property in revocable trusts).
• Trap Alert: Many candidates forget to include the full value of JTWROS property if the decedent provided all consideration, or only 50% if spouses.
• Determine the Adjusted Gross Estate (AGE):
• Gross Estate
• MINUS: Funeral and administrative expenses
• MINUS: Debts of the decedent
• MINUS: Outstanding medical expenses (if elected on estate return instead of final income tax return)
• MINUS: Casualty and theft losses
• Calculate the Taxable Estate:
• Adjusted Gross Estate
• MINUS: Marital Deduction (unlimited for transfers to U.S. citizen spouse)
• MINUS: Charitable Deduction (unlimited for qualified charities)
• MINUS: State Death Tax Deduction (if applicable)
• Add Adjusted Taxable Gifts (ATGs): These are taxable gifts made by the decedent after December 31, 1976. Remember, these are gifts that exceeded the annual exclusion at the time they were made and used up some of the donor's lifetime exemption.
• Crucial Point: ATGs are added back to the taxable estate to determine the total cumulative transfers, but not their value at death, only their value at the time of the gift.
• Calculate Tentative Estate Tax: Apply the unified transfer tax rates (up to 40% for 2024) to the sum of (Taxable Estate + Adjusted Taxable Gifts).
• Subtract Gift Taxes Payable: Subtract the gift taxes that would have been payable on the ATGs (if any) using the current unified rate schedule, not the rates at the time the gifts were made. This prevents double taxation.
• Subtract the Unified Credit: Apply the Basic Exclusion Amount (BEA) through the unified credit. For 2024, the BEA is $13.61 million, translating to a unified credit of $5,350,800. This credit is reduced by any unified credit previously used against lifetime taxable gifts.
• Subtract Other Credits: State death tax credit, foreign death tax credit, prior transfer tax credit.
• Result: Net Federal Estate Tax Payable.

Key Thresholds and Rules (2024, subject to inflation adjustment for 2026)

• Annual Gift Tax Exclusion: $18,000 per donee per year. This allows you to transfer wealth without using your lifetime exemption or paying gift tax. Spouses can "gift split" to exclude $36,000 per donee per year.
• Basic Exclusion Amount (BEA) / Lifetime Gift & Estate Tax Exemption / GST Exemption: $13.61 million per individual. This is the amount of combined taxable gifts and taxable estate that can pass free of federal transfer tax.
• Generation-Skipping Transfer (GST) Tax: Applied in addition to gift or estate tax when transfers skip a generation (e.g., grandparent to grandchild). The GST exemption is also $13.61 million.
• Portability: The Deceased Spousal Unused Exclusion Amount (DSUEA) allows a surviving spouse to use any unused BEA of their deceased spouse. An estate tax return (Form 706) must be filed to elect portability, even if no tax is due.
• Qualified Transfers: Unlimited exclusion for direct payments of tuition or medical expenses to the educational institution or medical provider. This does not count against the annual gift exclusion.
• Marital Deduction: Unlimited for transfers to a U.S. citizen spouse.
• Charitable Deduction: Unlimited for transfers to qualified charities.

Basis Rules: The Income Tax Angle

Understanding basis is crucial for advising on asset transfers:

• Gifted Property: The donee generally takes the donor's adjusted basis (carryover basis). If the FMV at the time of the gift is less than the donor's basis, a "double basis rule" applies:
• For gain calculation: Donee uses donor's basis.
• For loss calculation: Donee uses FMV at the time of the gift.
• Inherited Property: The beneficiary receives a basis equal to the Fair Market Value (FMV) of the property on the date of the decedent's death (or the Alternate Valuation Date, if elected, which is 6 months after death). This is known as a step-up in basis.
• Trap Alert: The step-up in basis only applies to assets included in the decedent's gross estate. Assets gifted during life generally retain their carryover basis for the donee.

Example: Estate Tax Calculation with Prior Taxable Gifts

Let's look at Susan, a single individual who dies in 2026.

• Her Gross Estate is $15,000,000.
• Funeral and administrative expenses are $200,000.
• She made $1,000,000 in taxable gifts in 2010. These gifts used $1,000,000 of her lifetime exemption at that time, and no gift tax was paid due to the unified credit.
• Assume the 2026 Basic Exclusion Amount (BEA) is $14,000,000 (adjusted for inflation from 2024's $13.61M).

Step-by-Step Calculation:

• Gross Estate: $15,000,000
• Adjusted Gross Estate: $15,000,000 (Gross Estate) - $200,000 (Expenses) = $14,800,000
• Taxable Estate: $14,800,000 (No marital or charitable deductions in this example)
• Add Adjusted Taxable Gifts (ATGs): $1,000,000
• Total for Tentative Tax Calculation: $14,800,000 + $1,000,000 = $15,800,000
• Calculate Tentative Estate Tax: Using the 2024 unified tax rate schedule (max 40%), this amount would incur a tax. For simplicity, let's assume a flat 40% for amounts over the BEA for this example's total transfers.
• Taxable amount above BEA: $15,800,000 - $14,000,000 (2026 BEA) = $1,800,000
• Tentative Tax: $1,800,000 * 40% = $720,000 (This is a simplified example; actual calculation uses a progressive schedule and includes tax on the full $14M within the BEA, then applies the credit.)
• Subtract Gift Taxes Payable: Susan paid $0 gift tax in 2010 because her $1M gift was covered by her unified credit. So, $0 here.
• Subtract Unified Credit: Her full BEA is $14,000,000. The unified credit for this BEA is $5,488,000 (40% of $14,000,000, simplified).
• However, she used $1,000,000 of her BEA in 2010. So her remaining available BEA is $14,000,000 - $1,000,000 = $13,000,000.
• The unified credit she actually gets to apply against the tentative estate tax is based on her remaining BEA.
• Common Trap: Candidates might mistakenly apply the full unified credit against the tentative tax, forgetting that the ATGs already consumed part of it. The system handles this by calculating tax on the cumulative transfers and then subtracting the full unified credit, effectively only taxing the amount above the lifetime exemption.
• Let's re-run step 6 and 7 more precisely.
• Tax on $15,800,000 (using a simplified 40% for amounts over $1M, and standard rates below) - assume this results in $6,320,000 (hypothetical, using 40% flat for illustrative purposes).
• Subtract hypothetical gift taxes payable on $1,000,000 (if they were paid, $0 in this case).
• Subtract the full unified credit corresponding to the 2026 BEA ($14,000,000) = $5,488,000.
• Net Estate Tax Payable (simplified): $6,320,000 - $5,488,000 = $832,000.

This example highlights that the unified credit is a single, lifetime credit used against both gift and estate taxes. The ATGs increase the bracket for estate tax, but the total credit is still applied.

Common Traps and Test-Day Reminders

The CFP exam loves to test your ability to differentiate between similar-sounding concepts or to catch nuances in calculations.

• Gift Tax vs. Estate Tax Payer: Remember, the donor is primarily liable for gift tax, while the estate (or its beneficiaries) is liable for estate tax. This seems basic but can be a distractor in case studies asking about who bears the tax burden.
• Income Tax Basis vs. Estate Tax Value: This is a huge one.
• Trap: Assuming all assets get a step-up in basis at death.
• Reality: Only assets included in the decedent's gross estate receive a step-up (or step-down) to FMV at death. Assets that were gifted during life (and not included in the gross estate) retain their carryover basis to the donee. This is why gifting highly appreciated assets to a donee who then sells them can trigger significant capital gains, whereas holding them until death could avoid those gains for the heir.
• Revocable vs. Irrevocable Trusts:
• Revocable Trusts: Assets placed in a revocable trust are still considered part of the grantor's gross estate for estate tax purposes. They avoid probate but offer no estate tax advantages during the grantor's life.
• Irrevocable Trusts: If properly structured (grantor gives up control), assets are generally removed from the grantor's gross estate, providing potential estate tax savings. However, they are irrevocable!
• Property Titling and Probate:
• JTWROS (Joint Tenancy With Right Of Survivorship) & Tenancy by the Entirety: Avoid probate, pass directly to surviving owner(s). Only 50% included in gross estate for spouses, but 100% if tenants are not spouses and decedent contributed all consideration.
• Tenancy in Common: Does not avoid probate. Each co-owner's interest passes to their heirs via their will or intestacy.
• Community Property (in some states): Each spouse owns an undivided half interest. At death, both halves (the decedent's and the survivor's) receive a step-up in basis to FMV, offering a significant income tax advantage.
• The Crummey Power: This allows gifts to an irrevocable trust to qualify for the annual gift tax exclusion. Without it, gifts to a trust (which typically aren't "present interests") wouldn't qualify. The power must give the beneficiary a temporary right to withdraw the gifted amount.
• The "5 and 5" Rule: A power of appointment held by a beneficiary that lapses is taxable if it exceeds the greater of $5,000 or 5% of the trust's principal. Be mindful of this in questions involving powers of withdrawal.
• DSUEA Election: Remember, portability isn't automatic! The executor of the deceased spouse's estate must file a timely Form 706 (even if no estate tax is due) to elect portability of the DSUEA for the surviving spouse.

Mnemonics and Memory Aids

Estate planning terms can be overwhelming. Here are some techniques and specific mnemonics to help them stick:

General Mnemonic Strategies

• Acronyms: Create short, memorable words from the first letter of a list of items.
• Visualizations: Imagine the concept in a vivid, even absurd, way.
• Rhymes/Jingles: Simple rhymes can make complex rules easier to recall.
• Flashcards: Convert key formulas, definitions, and thresholds into physical or digital flashcards. VoraPrep's adaptive learning engine helps you target weak areas, which is perfect for identifying what to put on flashcards.

Estate Planning Mnemonics

• D.E.A.D. (Valid Will Requirements):
• Donative intent: The testator intends the document to be their will.
• Executed properly: Signed by testator, witnessed (usually 2-3 disinterested witnesses), and sometimes notarized.
• Age 18 or older: Testator must be of legal age.
• Disposition of property: Specifies how assets are distributed.
• Bonus "S" for Sound Mind: Legal capacity/Sound mind is also critical.
• TTIP (Joint Tenancy with Right of Survivorship - JTWROS): Four unities required for JTWROS:
• Time: Interests acquired at the same time.
• Title: Interests acquired by the same instrument.
• Interest: All tenants have equal undivided interests.
• Possession: All tenants have equal rights to possess the property.
• Why this matters: If any unity is broken, the tenancy reverts to tenancy in common, losing the right of survivorship!
• A.B.C. (Charitable Remainder Trusts):
• Annuity Trust (CRAT): Pays a fixed dollar amount annually. No additional contributions allowed.
• B unitrust (CRUT): Pays a fixed percentage of the trust's assets, revalued annually. Additional contributions allowed.
• Charitable Lead Trust (CLT): The charity gets the income interest first, then the non-charitable beneficiary gets the remainder. (Opposite of CRAT/CRUT).
• GRATs, GRUTs, GRITs (Grantor Retained Trusts): These are all types of grantor retained trusts where the grantor retains an interest.
• GRAT (Grantor Retained Annuity Trust): Grantor retains the right to receive a fixed annuity payment for a term of years.
• GRUT (Grantor Retained Unitrust): Grantor retains the right to receive a fixed percentage of the trust's assets, revalued annually, for a term of years.
• GRIT (Grantor Retained Income Trust): Grantor retains the right to receive income from the trust for a term of years. (Less common now due to changes in law for non-family beneficiaries).
• Purpose: To transfer future appreciation of assets to beneficiaries at a reduced gift tax value, as the grantor's retained interest reduces the value of the gift.

What's worth memorizing? Focus on dollar thresholds, percentages, specific dates (like 1976 for ATGs), and the precise steps of tax calculations. For everything else, aim for conceptual understanding.

Frequently asked questions

What are the most important topics in CFP Estate Planning (CFP8)?

The most important topics include the federal gift and estate tax calculation framework, basis rules (especially step-up vs. carryover), various forms of property titling, and the different types and uses of wills and trusts. Understanding how these concepts interact is key.

What is the 2026 annual gift tax exclusion?

While the official 2026 figure is subject to inflation adjustments, the 2024 annual gift tax exclusion is $18,000 per donee. This allows individuals to give away this amount annually without incurring gift tax or using their lifetime exemption.

How does the unified credit work for estate and gift taxes?

The unified credit is a single, lifetime credit that applies to both taxable gifts made during life and the taxable estate at death. It effectively covers transfers up to the Basic Exclusion Amount (BEA), which is $13.61 million per individual for 2024 (adjusted for inflation each year). Any portion of the BEA used for lifetime taxable gifts reduces the amount available at death.

What is portability in estate planning?

Portability allows the unused federal estate tax exclusion amount of a deceased spouse (DSUEA) to be transferred to their surviving spouse. To elect portability, the executor of the deceased spouse's estate must file a timely Form 706 (U.S. Estate (and Generation-Skipping Transfer) Tax Return), even if no estate tax is due.
