Real estate investors often use a 1031 exchange to defer capital gains tax on one sale at a time, but the strategy can also be part of a much longer arc: a lifetime of deferral followed by a wealth transfer to the next generation. This is the idea behind 1031 exchange estate planning, sometimes called “swap till you drop,” which pairs repeated exchanges during an investor’s life with the step-up in basis that heirs receive under Section 1014 when they inherit property. Used thoughtfully, and with the right professionals involved, this approach can help a family preserve wealth across generations while avoiding a large, one-time capital gains tax bill.
If you are thinking about how a 1031 exchange fits into your long-term estate plan, talk with Aspen Exchange before your next sale to make sure the transaction is structured correctly.
How “Swap Till You Drop” Works
The core idea is straightforward. Each time an investor sells appreciated real estate and completes a valid like-kind exchange, the capital gains tax on that appreciation is deferred, not eliminated, because the investor’s basis carries over into the replacement property. If the investor exchanges property repeatedly over the years, perhaps trading up in value, consolidating multiple properties, or diversifying into different markets or asset types, the deferred gain keeps growing along with the portfolio.
The strategy gets its nickname from what happens if the investor never sells for cash during their lifetime and instead continues exchanging, or simply holds the final replacement property, until death. Under Section 1014 of the Internal Revenue Code, property included in a decedent’s estate generally receives a basis adjustment to its fair market value as of the date of death (or an alternate valuation date, in certain circumstances). For heirs, this basis adjustment is often referred to as a “step-up,” because the property’s basis is typically adjusted upward to reflect its current market value after years of appreciation.
The practical result is that decades of deferred gain, gain that would have triggered a large tax bill if the property had simply been sold, can potentially be eliminated for income tax purposes when the property passes to heirs. The heirs’ basis becomes the stepped-up value, so if they later sell the property near that value, there may be little or no capital gains tax due on the appreciation that occurred during the original owner’s lifetime.
Why Investors Use Exchanges Instead of Just Holding Property
An investor does not need to exchange property to benefit from the step-up in basis at death; simply holding appreciated real estate until death can also produce a stepped-up basis for heirs. So why combine this with exchanging along the way? Investors generally use 1031 exchanges throughout their lifetime for reasons that go beyond the eventual step-up, including:
- Portfolio management. Exchanging allows an investor to move out of properties that require heavy management, are in declining markets, or no longer fit their goals, without triggering a tax bill that would shrink the capital available to reinvest.
- Consolidation or diversification. An investor might exchange several smaller properties into one larger, more efficiently managed asset, or spread proceeds from one large property into several smaller ones in different markets.
- Income and cash flow adjustments. As investors age, many look to exchange into property types that require less hands-on management, such as certain net-leased assets, while keeping their capital fully working.
- Preserving purchasing power. Because the full amount of proceeds (minus transaction costs) can roll into the next property rather than being reduced by a tax bill, the investor’s buying power for the replacement property is generally preserved.

How This Interacts With Estate Tax Exposure
The step-up in basis addresses income tax on capital gains, but it is a separate matter from federal estate tax, which applies to the value of a decedent’s overall taxable estate above the federal exemption amount. That exemption amount is set by statute and adjusted periodically, and it has been the subject of legislative change over the years, so investors should not assume a specific figure will remain in place. For estates that may approach or exceed the applicable federal exemption, or that are subject to a state estate or inheritance tax with a lower threshold, the value of real estate held until death (including property accumulated through years of exchanging) can itself become a planning consideration, separate from the income tax benefit of the step-up.
In other words, a family could successfully defer and then eliminate capital gains tax exposure through the swap till you drop approach, while still facing estate tax exposure on the value of that same real estate if the estate is large enough. This is exactly why estate tax planning and 1031 exchange planning are usually discussed together rather than treated as separate topics.
Tools that sometimes come up in these conversations, depending on a family’s specific goals and circumstances, include irrevocable trusts, family limited partnerships, gifting strategies during life, and charitable planning vehicles. Whether any of these fit a particular family depends entirely on individual circumstances and should be evaluated with an estate planning attorney, not assumed from general information.
Why Coordinating With an Estate Attorney Matters
A 1031 exchange is fundamentally a real estate and tax transaction, but when it is being used as part of a long-term estate strategy, the legal structure around ownership matters enormously. A few areas where coordination with an estate planning attorney (alongside a CPA and the qualified intermediary) becomes important include:
- How title is held. Whether property is held individually, in a revocable living trust, in an LLC, or in another entity affects both how future exchanges can be structured and how the property passes at death.
- Trust and entity documents. If real estate held for exchange purposes sits inside a trust or partnership, the underlying documents need to be reviewed to confirm they support the family’s long-term plan and do not inadvertently create complications for a future exchange.
- Basis tracking across multiple exchanges. Because basis carries forward through each exchange, keeping accurate records of the original basis and each subsequent exchange is essential so that the eventual step-up calculation, and any partial taxable gain along the way, can be determined accurately.
- Coordinating timing with the taxpayer’s overall estate plan. An attorney can help ensure that an exchange completed late in an investor’s life does not create administrative complications for the estate, and that beneficiaries understand how the property they are inheriting was acquired.
- Multiple owners or family members. When property is co-owned by family members, or when an exchange involves interests held by multiple parties, the legal structure needs particular care to keep everyone’s individual exchange eligibility intact.
Because the strategy touches income tax, estate tax, and real estate law simultaneously, no single advisor typically has the full picture alone. Coordinating a CPA, an estate planning attorney, and an experienced qualified intermediary gives a family the best chance of executing the strategy the way it was intended.
Frequently Asked Questions
Does the step-up in basis apply automatically to any property acquired through a 1031 exchange?
Generally, yes, real property included in a decedent’s estate can receive a basis adjustment to fair market value under Section 1014, regardless of whether that property was originally acquired through a 1031 exchange. The exchange history affects the carried-over basis prior to death, but the step-up rule itself applies to qualifying property in the estate.
Do heirs need to do anything special to receive the step-up in basis?
Heirs generally do not need to take a specific action to receive the basis adjustment, but proper documentation of the property’s fair market value as of the date of death (often through an appraisal) is typically important for accurately establishing the new basis for future tax reporting.
Can I still exchange property if I am elderly or have health concerns?
Age or health alone generally does not disqualify someone from completing a 1031 exchange, but the strict 45-day and 180-day deadlines still apply, so it is worth discussing timing and contingency planning with your advisors and family in advance.
What happens if I sell exchanged property for cash instead of passing it to heirs?
If you sell for cash during your lifetime instead of holding until death or completing another exchange, the previously deferred gain generally becomes taxable in the year of that sale, similar to any other property sale.
Does swap till you drop eliminate estate tax as well as capital gains tax?
No. The step-up in basis primarily addresses income tax on capital gains. Federal and, in some cases, state estate tax is a separate consideration based on the overall value of the estate and the applicable exemption amounts, and should be planned for separately with an estate attorney.
Should I involve my heirs in the planning process?
Many families choose to involve heirs, at least at a high level, so they understand the basis history of inherited property and know who to contact regarding past exchanges. This is a personal decision that your estate attorney can help you think through.
