Advanced Estate Planning Strategies for Real Estate and Investment Portfolios

How real estate and investment portfolios are taxed at death

Two separate tax rules apply when you pass on real estate or a brokerage account: the step-up in basis and the federal estate tax. They work differently, and mixing them up leads to bad decisions.

The step-up in basis resets an asset's cost basis to its fair market value on the date of death. Cost basis is what you paid for something, plus improvements, minus any depreciation you already claimed. If your heir sells the asset soon after inheriting it, there is little or no taxable gain, because the gain is measured from the new, stepped-up value, not your original purchase price. This rule applies to nearly every capital asset, whether or not your estate owes any estate tax. The IRS covers the mechanics in Topic 703, and Publication 551 covers inherited property in more detail.

The federal estate tax is a separate, much rarer tax. It only applies once your total estate, including real estate and investments at current fair market value, exceeds the federal exemption. For 2026, that exemption is $15,000,000 per individual, so most households never owe federal estate tax even with a valuable property portfolio. The two rules interact at the top of the wealth range: an estate large enough to owe estate tax still gets the basis step-up on the assets that pass through it, so planning usually focuses on staying under the exemption while keeping the step-up wherever possible.

Estate tax exemptions by state

Most states do not have their own estate tax. As of 2026, twelve states plus Washington, DC still do, and their exemptions sit far below the federal $15,000,000 figure.

Oregon has the lowest threshold in the country, at $1,000,000. Massachusetts starts at $2,000,000, and Washington starts at roughly $3,000,000 (the exact figure resets slightly each July). Other states with their own estate tax include Illinois, Maryland, Vermont, Hawaii, Maine, New York, Minnesota, Rhode Island, and Connecticut, each with its own threshold and rate schedule. A separate group of states, including Kentucky, Maryland, Nebraska, New Jersey, and Pennsylvania, taxes beneficiaries directly through an inheritance tax instead of, or alongside, an estate tax.

This matters most for real estate investors, because property value is concentrated and hard to discount. A rental portfolio worth $2,500,000 clears Oregon's threshold with room to spare, even though it is nowhere near the federal exemption. If you own property in a state estate tax state, run the numbers with our estate tax calculator before assuming the federal exemption is the only number that matters. Domicile at death controls which state's rules apply, so some households relocate to a no-estate-tax state, like Florida or Texas, well before any transfer becomes urgent.

Transferring real estate: core strategies

Real estate is illiquid and hard to divide, so transferring it takes more planning than a brokerage account. A few core approaches cover most situations.

Outright gifting moves a property out of your estate right away, but the recipient inherits your original cost basis, not a stepped-up one, so a later sale can trigger a large capital gains bill. A sale to an irrevocable trust, instead of a gift, can freeze the property's value in your estate while shifting future appreciation to your heirs (more on this under the IDGT section below). Deed-based tools, like a transfer-on-death deed or, in a handful of states, a lady bird deed, move a single property outside probate at low cost; see our living trust vs lady bird deed comparison for how that stacks up against a full trust.

For a primary residence specifically, a Qualified Personal Residence Trust can remove the home from your estate at a discounted gift value. For a portfolio of rental or investment properties, a Family Limited Partnership or family LLC can consolidate ownership and pass minority interests to the next generation at a discount. Both are covered in detail below.

Qualified Personal Residence Trust (QPRT)

A Qualified Personal Residence Trust, or QPRT, moves your home or vacation house out of your taxable estate while letting you keep living there for a set number of years. You transfer the house into the trust and pick a term, commonly 10 to 15 years. During that term, you live in the home rent-free, exactly as before.

The tax benefit comes from how the gift is valued. Because you keep the right to live there for the term, the IRS values your gift at less than the home's full market value, using a formula tied to your age, the term length, and current interest rates. A bigger gap between the discounted gift value and the home's real value means a bigger tax win, which is why a QPRT works best for a grantor who is confident they will outlive the term.

That confidence is the catch. If you die before the term ends, the home's full value snaps back into your taxable estate, and you gain nothing beyond what a will would have done anyway. If you do outlive the term, ownership passes to your children or a trust for their benefit. If you want to keep living in the house after that, you now have to pay them fair-market rent. Skip the rent, and the IRS can treat the arrangement as if you never gave up the house at all, undoing the plan you paid an attorney to build.

Family Limited Partnership or LLC

A Family Limited Partnership (FLP) or family LLC is a legal entity that holds a family's real estate, business interests, or investments. Parents typically start as the general partner or manager, while children or trusts hold limited interests. It is a common tool for a family that owns several rental properties, a farm, or an operating business.

The tax benefit comes from valuation discounts. A minority interest in an FLP cannot be sold easily and carries no control over the entity, so appraisers value it below its proportional share of the underlying assets. Parents can gift or sell limited partnership interests to children at that discounted value, moving more wealth out of the estate for the same dollar of gift or estate tax exemption used.

The IRS scrutinizes FLPs closely, and the risk is real. If parents keep too much control, mix personal expenses with entity funds, or skip formalities like separate bank accounts and real partnership meetings, the IRS can argue the whole structure lacked a legitimate business purpose. Under IRC §2036, that argument can pull the full, undiscounted value of the assets back into the taxable estate, erasing the benefit and leaving a costly audit behind. An FLP only works when it is run like a real business, not a paperwork shortcut.

Transferring investment portfolios: core strategies

Brokerage and retirement accounts move differently than real estate, mostly because they are liquid and easy to divide. A few core approaches apply.

Transfer-on-death (TOD) and payable-on-death (POD) designations move an account directly to a named beneficiary outside of probate, at no cost, and should be the default for any account that does not need trust protections. For appreciated stock you plan to give away anyway, donating shares directly to a donor-advised fund or a charity avoids capital gains tax entirely and still earns a charitable deduction, which beats selling first and donating the cash.

For a concentrated stock position or a fast-growing portfolio you want to pass to family, two irrevocable trust structures do most of the work: a Grantor Retained Annuity Trust (GRAT) and an Intentionally Defective Grantor Trust (IDGT). Both let future growth pass to your heirs largely free of gift and estate tax, and both are explained in the next two sections. Diversifying a concentrated position before using either tool usually makes the numbers work better, since a single stock's volatility can undercut the strategy in a bad year.

Intentionally Defective Grantor Trust (IDGT)

An Intentionally Defective Grantor Trust, or IDGT, is an irrevocable trust built with a specific quirk on purpose. It is "defective" for income tax purposes, meaning you, the grantor, keep paying the income tax on the trust's earnings. It is fully effective for estate tax purposes, meaning the assets inside it are out of your taxable estate.

The usual way to fund an IDGT is a sale, not a gift. You sell an appreciating asset, like a portfolio of stock or a rental property, to the trust in exchange for a promissory note at a modest interest rate set by the IRS. Your estate keeps only the note's value, frozen at the sale date, while every dollar of growth above the note's interest rate builds up inside the trust for your heirs, outside your estate.

Paying the trust's income tax yourself is actually a bonus: it is not treated as an additional taxable gift, so it lets you shrink your own estate every year without using any exemption. The risk sits on the other side. If the trust's investments underperform the note's interest rate, you have given up an appreciating asset for a note that barely grew, and the strategy produces little or no benefit. You are also on the hook for the trust's income taxes for as long as the trust exists, which is a real ongoing cash drain most people underestimate going in.

Grantor Retained Annuity Trust (GRAT)

A Grantor Retained Annuity Trust, or GRAT, works like a bet against the IRS's own interest rate. You transfer assets into the trust and keep the right to fixed annuity payments back for a set term, often two to five years. Whatever is left in the trust when the term ends passes to your beneficiaries.

The IRS assumes the trust assets will grow at a set rate, called the Section 7520 rate (sometimes called the hurdle rate), published monthly. If the assets actually grow faster than that rate, the extra growth passes to your heirs with little or no gift tax owed. Many households use a "zeroed-out" GRAT, structured so the annuity payments equal almost the entire value transferred, which keeps the taxable gift close to zero from the start.

The catch is mortality risk. If you die before the GRAT term ends, the trust assets, or at least the portion needed to support the remaining annuity payments, are pulled back into your taxable estate, and the strategy provides no benefit. Because of that risk, many families use a series of short, rolling GRATs rather than one long one, so a single badly timed term does not undo the whole plan. A GRAT has little downside beyond legal fees and lost time if it fails, but it has no upside if you do not outlive the term.

Irrevocable Life Insurance Trust (ILIT)

An Irrevocable Life Insurance Trust, or ILIT, is an irrevocable trust that owns a life insurance policy on your life instead of you owning it directly. Because the trust, not you, owns the policy, the death benefit is paid to the trust outside your taxable estate, even though the payout can still be many times the premiums paid in.

An ILIT works best for households whose estate is cash-poor relative to its value, commonly a family with a large real estate portfolio and not much liquid cash. The trust's tax-free death benefit can pay estate taxes or buy out an illiquid asset like a family business, without forcing a fire sale of property to raise cash.

The non-obvious risk is timing. If you transfer an existing policy you already own into the ILIT, the IRS applies a three-year lookback rule under IRC §2035(a): if you die within three years of the transfer, the policy's full value is pulled back into your taxable estate anyway. The fix is simple but easy to miss: have the trustee apply for and own a brand-new policy from day one, rather than transferring an old one, which sidesteps the lookback rule entirely. You also need to follow specific notice rules, often called Crummey notices, each time you gift premium money into the trust, or the gifts may not qualify for the annual exclusion.

The role of the stepped-up basis in planning decisions

Every strategy above involves a tradeoff between two benefits: moving an asset out of your taxable estate now, or leaving it in your estate so your heirs get the stepped-up basis later. You often cannot get both, so the choice deserves its own numbers.

Here is a real example. Say you bought a rental property years ago for $400,000, and it is now worth $2,400,000. Gain over that time: $2,000,000.

If you gift the property to your child today, your child's cost basis is your original $400,000, not the current value. If your child sells it soon after for $2,400,000, the taxable gain is $2,000,000. At the combined federal long-term capital gains rate of 20% plus the 3.8% net investment income tax, the tax bill is roughly $476,000 ($2,000,000 times 23.8%).

If you instead hold the property until you die and your child inherits it, the cost basis resets to the $2,400,000 fair market value at your death. If your child then sells it right away for the same $2,400,000, the taxable gain is $0, and the tax bill is $0.

That is a real, verifiable $476,000 difference in this example, driven entirely by timing. It ignores two real-world complications: depreciation recapture on rental property can add tax to a lifetime sale, and some states also tax capital gains on top of the federal rate. It also assumes your estate stays under the estate tax exemption, since an estate above the exemption pays 40% on the excess regardless of the basis rule. That is why gifting appreciated real estate or stock during life usually makes sense only for an asset you expect to keep growing fast, or one you want out of your estate for a state tax reason, or a gift to someone in a much lower tax bracket, not as a blanket rule.

How a financial advisor and estate planning attorney can help

None of the strategies above are DIY projects. Every one requires an attorney to draft the trust or entity documents precisely enough to survive IRS scrutiny, and most also require a coordinated financial plan to make the numbers work.

An estate planning attorney drafts the legal documents: the trust language, the FLP partnership agreement, the deed transfers, and the gift tax returns (Form 709) that report each transfer to the IRS. For anything above the basics, a specialist in trusts and estates matters more than a generalist, since small drafting errors, like a retained right or a missing formality, can undo an otherwise sound plan.

A financial advisor plays a different role: choosing which specific assets to put into which vehicle, checking whether a GRAT's assumed growth rate is realistic, and managing the trust's investments once it is funded. For a GRAT or an IDGT, the advisor's growth assumptions largely decide whether the strategy succeeds. A CPA rounds out the team, since irrevocable trusts file their own tax returns and gift tax returns carry their own filing rules.

Expect to pay more for this team than for the basics covered in our first-time estate planning guide. Attorney fees for a single irrevocable trust commonly run $2,500 to $10,000 or more, and an FLP or a multi-trust plan can run higher. That cost is usually small next to the tax it saves for an estate large enough to need these tools in the first place.
