Real Estate in Estate Tax Planning 2026 — Valuation, Appraisals, and Tax-Saving Strategies
Real estate is often the largest asset in an American estate — and the most complicated to value, transfer, and plan around. A family home, rental properties, commercial buildings, or land held for decades can trigger significant estate tax exposure that many families don’t anticipate until it’s too late.
This guide focuses exclusively on the real estate dimension of estate tax planning. For a broader overview of inheritance and gift tax strategy, see the companion post.
The Federal Estate Tax Landscape in 2026 — What You Must Verify
The Tax Cuts and Jobs Act (TCJA) of 2017 doubled the federal estate tax exemption, pushing it to approximately $13.61 million per individual in 2025 (indexed for inflation). Under TCJA, this higher exemption was scheduled to sunset after December 31, 2025, potentially reverting to pre-TCJA levels of around $7 million per individual (adjusted for inflation).
What this means for 2026: Legislation passed in 2025 may have extended, modified, or permanently altered the exemption. This is a moving target that you must verify with a qualified estate planning attorney. The difference between a $7 million and $13+ million exemption has enormous implications for real estate-heavy estates.
Why it matters for real estate: Real estate values have appreciated dramatically in most US markets over the past decade. A family that bought a rental property portfolio 20 years ago for $2 million may now hold assets worth $8–15 million. At certain exemption levels, that portfolio can trigger estate tax. At higher exemption levels, it may not.
State Estate Taxes — The Hidden Threat for Real Estate Owners
Even if your estate falls below the federal threshold, multiple states impose their own estate taxes with significantly lower exemptions. If you own real estate, state estate tax is assessed where the property is located — not where you live.
| State | Exemption (approx.) | Top Rate | Notable Feature |
|---|---|---|---|
| Massachusetts | $2 million | 16% | No portability between spouses |
| Oregon | $1 million | 16% | One of the lowest exemptions |
| Washington | $2.193 million | 20% | Highest state rate |
| New York | ~$7.16 million | 16% | “Cliff effect” — full estate taxed if >105% of exemption |
| Minnesota | $3 million | 16% | Includes non-resident real estate |
| Illinois | $4 million | 16% | Non-residents taxed on IL real estate |
| Maryland | $5 million | 16% | Only state with both estate and inheritance tax |
The cliff effect in New York deserves special attention. If a New York estate exceeds the exemption by even $1, the entire estate is subject to tax — not just the excess. This makes values just above the NY threshold particularly punishing for real estate owners.
Practical implication: A California resident who inherited a Manhattan apartment worth $5 million could owe NY state estate tax even though California has no estate tax and the estate might be under the federal exemption.

Step-Up in Basis — The Most Powerful Real Estate Estate Planning Tool
No discussion of real estate estate planning is complete without understanding stepped-up basis under IRC §1014.
How It Works
When a beneficiary inherits real estate, the tax basis is stepped up (or down) to the property’s fair market value on the date of death. The decedent’s original purchase price and accumulated depreciation become irrelevant.
Example: Your parent purchased a rental property in 1990 for $150,000. Over 30 years, they took $120,000 in depreciation, reducing their adjusted basis to $30,000. The property is worth $1.1 million at death. You inherit it with a $1.1 million basis. If you sell it immediately for $1.1 million, you owe zero capital gains tax — and the depreciation recapture that would have been owed disappears entirely.
Alternate Valuation Date — When Values Fall After Death
Under IRC §2032, the executor can elect to value the entire estate 6 months after the date of death — but only if:
- The total gross estate value is lower at the alternate date, AND
- The estate tax liability is lower at the alternate date
Both conditions must be satisfied simultaneously. You cannot cherry-pick which assets to value at which date.
This election matters when real estate values declined after the death — potentially reducing both estate tax and establishing a lower basis for the heirs.
The 1031-to-Death Strategy
Many experienced real estate investors use 1031 like-kind exchanges throughout their lifetime to defer capital gains, then hold the final replacement property until death. At death:
- Capital gains tax on the deferred gain disappears permanently (via step-up)
- The property exits the estate at current fair market value
- Heirs can sell without capital gains tax
This combination — 1031 exchanges during life, step-up at death — is one of the most tax-efficient strategies for appreciating real estate. The estate tax exposure grows, but for estates under the federal exemption, this can be essentially a tax-free generational transfer of substantial wealth.
Real Estate Appraisal Requirements for Estate Tax
The IRS requires that real estate in a taxable estate be valued at fair market value under Treasury Regulation §20.2031-1(b): “the price at which the property would change hands between a willing buyer and a willing seller, neither being under any compulsion to buy or to sell and both having reasonable knowledge of relevant facts.”
Three Appraisal Methods
1. Sales Comparison Approach: Most commonly used for residential property. Compares the subject property to recent sales of comparable properties, adjusted for differences. For inherited homes in active markets, this is typically the primary method.
2. Income Capitalization Approach: Used for income-producing property (rentals, commercial real estate). The appraiser estimates net operating income and applies an appropriate capitalization rate. This method requires current rent rolls, vacancy rates, and market cap rates.
3. Cost Approach: Estimates land value plus the depreciated replacement cost of improvements. Typically used for special-use properties with few comparables.
Appraisal Timing and Documentation
- The appraisal must reflect value as of the date of death (or alternate valuation date)
- A qualified appraisal must be conducted by a qualified appraiser under Treasury Reg. §1.170A-17
- For non-cash charitable contributions of real estate, the appraisal must be made no earlier than 60 days before the contribution and no later than the return due date
Valuation disputes with the IRS on real estate are common. The IRS has its own appraisers and will challenge valuations it deems too low. Having a well-documented, defensible appraisal from a licensed MAI-designated appraiser is essential.
Scenario Analysis: Valuation Strategies for Different Property Types
Scenario 1: Family Home — Standard Inheritance
Facts: Parent purchased a home in 1985 for $120,000. Current fair market value: $950,000. One adult child inherits.
- Estate tax: Assume estate is under the applicable federal exemption — no federal estate tax.
- State estate tax: Depends on state. If Oregon (exemption $1M), this property alone could push the estate near the threshold.
- Capital gains on sale: Zero (step-up to $950,000).
- Basis for ongoing depreciation (if child rents it): $950,000 — fully refreshed for future depreciation deductions.
Tax planning takeaway: For estates under the federal exemption, the step-up in basis at death is often worth more than any gift-tax-motivated transfer strategy during life.
Scenario 2: Rental Portfolio — Income Tax vs. Estate Tax Trade-Off
Facts: Couple owns four rental properties with total FMV of $8 million. Adjusted cost basis (after depreciation): $1.2 million. Combined estate including other assets: $11 million.
At death of first spouse with proper portability election, the surviving spouse has $27M+ combined exemption (if TCJA-level exemptions remain). At second death, estate is $11M — likely under federal threshold but potentially subject to state tax.
Options analyzed:
- Hold until death: Both spouses die, heirs get $8M of property with stepped-up basis, eliminating $6.8M of built-in gain. If estate is under exemption, no estate tax.
- Gift during lifetime: Removes appreciation from estate but transfers the low basis — heirs face capital gains on eventual sale.
- Family Limited Partnership: FMV $8M, transfer partnership interests at 20–25% discount. Gift tax value of transferred interests is reduced to $6–6.4M. However, IRS scrutiny is significant.
Conclusion: For appreciated portfolios under the federal exemption, hold-until-death dominates gift strategies unless state estate tax creates urgent motivation to transfer.
Qualified Personal Residence Trust (QPRT) — Freezing the Home’s Value
A QPRT is an irrevocable trust under IRC §2702 that allows a homeowner to transfer a primary or vacation home to heirs at a significantly reduced gift tax value.
How the Discount Works
The grantor retains the right to live in the home for a fixed term (e.g., 10 years). The gift to heirs is only the remainder interest — the right to own the property after the term. Using IRS §7520 interest rates and actuarial tables, the IRS discounts the present value of that future gift.
In a low §7520 rate environment, QPRT discounts are larger. In higher rate environments, the discount is smaller.
Risk Analysis
| Outcome | Result |
|---|---|
| Grantor survives the term | Property passes to heirs at discounted value, outside estate — strategy succeeds |
| Grantor dies during term | Full FMV returned to estate — gift tax paid on creation was wasted |
| Grantor needs to continue living in home after term | Must pay fair market rent to heirs — creates additional planning complexity |
QPRTs work best for relatively healthy grantors with terms of 10+ years, high-value homes in appreciating markets, and situations where state estate tax creates urgency below the federal exemption.
Family Limited Partnerships — Valuation Discounts on Real Estate
An FLP holding real estate can apply minority interest and lack of marketability discounts to reduce the gift or estate tax value of real estate transferred to family members. Typical discounts range from 15% to 35%.
IRS Scrutiny and Court Requirements
The IRS and courts have consistently challenged FLPs that lack economic substance. To withstand scrutiny:
- The FLP must have a legitimate non-tax business purpose (asset management, liability protection, centralized management)
- Proper formalities must be maintained (separate books, meetings, actual management activity)
- The decedent must not have retained control inconsistent with a limited partnership interest
- Assets should not be commingled with personal funds
IRS Rev. Rul. 93-12 confirmed that minority discounts apply to family transfers — but only when the structure has substance.
Scenario 3: FLP with Real Estate Portfolio
Facts: A parent owns real estate worth $6 million (FMV). Transfers 60% limited partnership interests to adult children via gift and sale, retaining 40% general partnership interest.
- Without FLP: Transferring $3.6M of real estate FMV triggers gift tax on $3.6M
- With FLP: 60% LP interest value, after 25% discount = $2.7M gift tax value
- Tax savings on transfer: ~$900,000 of reduced gift tax base
- Estate tax savings at death on remaining 40%: Additional discount on the GP interest further reduces taxable estate
These figures are illustrative. Discount percentages are fact-specific and must be supported by an independent qualified appraisal.
Portability — Protecting the Unused Exemption of the First Spouse to Die
One of the most underutilized estate planning tools for married real estate owners is portability under IRC §2010(c). When the first spouse dies, the executor can elect to transfer the unused federal estate tax exemption to the surviving spouse.
Why this matters for real estate: If a couple owns $10 million of real estate and the first spouse dies with a $5M estate, the unused $8.61M exemption (at TCJA levels) can be ported to the survivor. The survivor then has a combined ~$22M+ exemption — sufficient to cover the remaining $5M estate without any federal estate tax.
Critical requirement: Portability must be elected on a timely filed estate tax return (Form 706), even if no tax is owed. Many families lose portability because they don’t file a return when no tax is due, assuming it isn’t necessary.
Checklist — Real Estate Estate Tax Planning for 2026
Use this framework as a starting point before your next estate planning meeting:
- Determine current FMV of all real estate holdings using qualified appraisals
- Identify states where you own property — check each state’s estate/inheritance tax rules
- Confirm the current federal estate tax exemption and whether TCJA extensions apply
- File Form 706 to elect portability if a spouse recently died
- Review whether appreciated property should be held until death vs. transferred now
- Evaluate QPRT for primary or vacation residence if estate exceeds exemption
- Assess FLP structure for rental portfolios — ensure documentation and substance
- Verify life insurance is held in ILIT for liquidity to pay estate taxes
- Review community property classification if you live in or have moved from a community property state
- Update property deeds, beneficiary designations, and trust titles annually
Working With Professionals — Who You Need on Your Team
Real estate estate planning requires a coordinated team:
- Estate planning attorney: Drafts trusts (QPRT, ILIT, FLP documents), wills, powers of attorney
- CPA or tax advisor: Handles income tax implications, depreciation recapture, 1031 exchange planning
- Real estate appraiser (MAI-designated): Provides defensible FMV appraisals for IRS purposes
- Financial advisor: Coordinates life insurance and investment assets with estate plan
The cost of this team is typically a small fraction of the estate tax savings achieved through proper planning. For estates with real estate approaching the exemption threshold, professional guidance is not optional.

What is the federal estate tax exemption for 2026?
The federal estate tax exemption was approximately $13.61 million per individual ($27.22 million per married couple with portability) under TCJA. However, TCJA provisions were set to sunset after 2025. Legislation passed in 2025 may have altered this — you must verify current figures with a qualified estate attorney, as the exemption amount directly drives whether your estate owes federal tax.
Which states have their own estate taxes with lower exemption thresholds?
As of 2026, states including Massachusetts, Oregon, Washington, Minnesota, Illinois, and Maryland impose state estate taxes with exemptions far below the federal level — sometimes as low as $1 million. New York has a 'cliff effect' where exceeding the exemption by even $1 causes the full taxable estate to be subject to state tax. If you own property in these states, state tax may apply even when federal tax does not.
How does the step-up in basis work for inherited real estate?
When you inherit real estate, your cost basis is generally stepped up to the fair market value on the date of death (or alternate valuation date, if elected). This means if your parent bought a property for $200,000 and it's worth $800,000 at death, your basis is $800,000 — not $200,000. You can sell the property immediately with little or no capital gains tax. This is one of the most powerful tax benefits of holding appreciated property until death.
What is a Qualified Personal Residence Trust (QPRT) and how does it save estate taxes?
A QPRT transfers your home into an irrevocable trust while you retain the right to live there for a fixed term (e.g., 10-15 years). The gift to your heirs is discounted because they don't take possession immediately — the IRS calculates the present value of the future interest. If you survive the trust term, the home passes to beneficiaries at the discounted value, out of your taxable estate. The risk: if you die during the trust term, the full value returns to your estate.
Can a Family Limited Partnership reduce estate tax on real estate?
Yes, FLPs are a legitimate strategy to apply valuation discounts — typically 15–35% — to real estate holdings transferred to family members. Discounts are justified by lack of control and lack of marketability of the partnership interests. The IRS scrutinizes FLPs heavily, and courts have disallowed discounts where the partnership lacked economic substance. Proper structure and documentation are essential.
Does a 1031 exchange eliminate estate tax on real estate?
A 1031 exchange defers capital gains tax during your lifetime — it does not reduce estate tax. The full fair market value of the replacement property is included in your taxable estate at death. However, the step-up in basis at death effectively eliminates the deferred capital gain from the 1031 exchange, so heirs can sell the inherited property without capital gains tax. This combination makes 1031-to-death a powerful long-term strategy.
What appraisal is required for estate tax purposes on real estate?
IRC §7520 and Treasury Regulation §20.2031-1(b) require that real estate be valued at its fair market value — the price a willing buyer would pay a willing seller, neither under compulsion. For estate tax, this typically requires a qualified appraisal from a licensed appraiser using recognized methods: sales comparison, income capitalization, or cost approach. The appraisal must meet IRS requirements under Treasury Reg. §1.170A-17 to be relied upon.
How does the alternate valuation date work for estate tax?
Under IRC §2032, the executor can elect to value the estate as of 6 months after the date of death if both the total estate value and the estate tax liability decrease. This can benefit estates where real estate values declined after death. Both conditions must be satisfied — you cannot use the alternate date selectively on just one asset.
What is the difference between estate tax and inheritance tax?
Estate tax is levied on the decedent's estate before distribution. Inheritance tax is levied on the beneficiary receiving assets. The federal government imposes estate tax; there is no federal inheritance tax. Some states (Iowa, Kentucky, Maryland, Nebraska, New Jersey, Pennsylvania) impose inheritance tax. Maryland is the only state with both. Real estate is subject to estate or inheritance tax in the state where the property is physically located, regardless of where the deceased lived.
Can life insurance proceeds help pay estate taxes on real estate that is hard to sell?
Yes — holding life insurance in an Irrevocable Life Insurance Trust (ILIT) keeps the proceeds out of the taxable estate while providing liquidity to pay estate taxes. This avoids forced sale of real estate to cover tax bills. The ILIT must be structured correctly — the decedent cannot own the policy outright. Many estate planners combine ILITs with real estate-heavy estates specifically for this liquidity purpose.
What are the most common estate tax mistakes for real estate owners?
The most common mistakes are: (1) failing to update property appraisals before death, (2) overlooking state estate or inheritance taxes, (3) assuming 1031 exchanges eliminate estate tax, (4) failing to document FLP economic substance, (5) letting QPRT terms expire without proper planning, (6) not using portability to preserve the deceased spouse's unused exemption, and (7) ignoring real estate in community property states which can affect basis step-up rules.
How does real estate in community property states affect estate tax planning?
In community property states (California, Texas, Arizona, Nevada, Washington, Idaho, Louisiana, New Mexico, Wisconsin), both spouses receive a full step-up in basis on community property at the death of either spouse — not just the decedent's half. This means a couple who jointly owned property bought for $400,000 worth $1.2 million gets a full step-up to $1.2 million in the surviving spouse's hands. This dramatically reduces capital gains tax exposure.
