1031 Exchange vs Selling and Buying Stocks: The After-Tax Math on Real Estate vs a Brokerage Account

The decision is whether the gain tax is paid now or kept working, because stock cannot receive exchange money

Section 1031(a)(1) defers gain only when real property is exchanged for real property of like kind. Since the 2017 amendments the section has covered nothing else, and Reg. section 1.1031(a)-3(a)(5) lists stock, bonds, notes and partnership interests as intangibles that are never real property, whatever state law says.

So the stock route is always a taxable sale followed by a purchase with what is left. That also covers real estate investment trust shares and real estate mutual funds: the underlying assets are buildings, but what you buy is stock.

The exchange route keeps every dollar of equity in real estate and carries your old basis into the new property under section 1031(d). Neither route is wrong. They price the same gain differently, and the rest of this page lays out the trade.

Worked model: a $1,000,000 rental sale leaves $866,189 for stocks and $1,000,000 for real estate

Hypothetical round numbers for a married couple filing jointly with $150,000 of other taxable income. They bought a rental for $600,000, claimed $200,000 of depreciation and sell with $1,000,000 of net proceeds and no mortgage. Brackets come from Rev. Proc. 2025-32; state tax is left out and would widen the gap.

The $133,811 is 22.3% of the gain. In the exchange it stays invested, and at any equal rate of return the real estate starts with 15.4% more capital than the brokerage account. Run your own numbers with your CPA; the four-layer method behind these figures is on how much tax you pay selling a rental without a 1031.

• Gain: $1,000,000 less $400,000 adjusted basis = $600,000, of which $200,000 is unrecaptured section 1250 gain and $400,000 is other long-term gain.
• Depreciation layer stacked from $150,000 to $350,000: $61,400 at 22% and $138,600 at 24% = $46,772.
• Capital gain layer from $350,000 to $750,000: $263,700 at 15% and $136,300 at 20% = $66,815.
• Net investment income tax: modified AGI of $782,200 exceeds $250,000 by $532,200; 3.8% of that is $20,224.
• Federal tax $133,811. Stock path starts with $866,189; exchange path starts with $1,000,000 of replacement property.

Income from each side is taxed differently: dividends get capital gain rates, rents get depreciation

Qualified dividend income is added to net capital gain by section 1(h)(11), so most dividends from domestic companies are taxed at 0%, 15% or 20% rather than ordinary rates. Interest and non-qualified dividends are ordinary income.

Rent is ordinary income, but it is reduced by depreciation: section 168(c) writes off residential rental buildings over 27.5 years and nonresidential buildings over 39. That deduction can shelter part or all of the cash a property throws off. In an exchange, though, the replacement starts from your carried-over basis, so the shelter is smaller than it would be on a fresh purchase.

Both streams count toward the 3.8% net investment income tax in section 1411, which reaches interest, dividends, rents and gains once modified AGI passes $250,000 joint or $200,000 single.

Leverage and diversification point in opposite directions, so decide which one you are paying for

Real estate is commonly bought with a mortgage, and an exchange that pays off a loan must replace that debt or add cash, or the shortfall becomes taxable boot; see whether to replace the mortgage or add cash. Stocks can be bought on margin, but Regulation T sets initial margin at 50% of market value for margin equity securities, and a falling market can force sales at the worst time.

Diversification runs the other way. A brokerage account can hold thousands of companies, trade any business day and be sold in pieces. A single rental is one tenant base, one roof and one local economy, and it sells whole. Owners who want the deferral without the concentration often split exchange proceeds across several Delaware Statutory Trust interests, each holding different buildings, accepting that DST interests are illiquid; see DST illiquidity and exits.

Exit tax drag is heavier on the real estate side unless you hold until death, where section 1014 favours the exchange

If both portfolios are eventually sold for cash, the real estate owner pays everything that was deferred: the original $600,000, any new gain, and depreciation taken on the replacement. The stock owner already paid the first round and owes tax only on growth above the $866,189 basis, with no depreciation layer at all.

Death changes the arithmetic. Section 1014(a)(1) gives heirs a basis equal to fair market value at the date of death for both stocks and real estate. The stock path already paid $133,811 that nobody gets back; the exchange path's deferred gain simply disappears. That is why owners who expect to hold for life usually exchange, which 1031 vs holding for step-up explores further.

Owners who need to spend the money within a few years face the opposite pull: deferral buys little when the tax comes due soon, and the stock account is easier to draw from.

How to choose, including the partial path where some cash goes to stocks and the rest stays deferred

Lean toward the exchange if you expect to hold until death, want income sheltered by depreciation and can accept illiquidity. Lean toward stocks if you need liquidity, want to be done with property risk, or are in a low-income year where much of the gain falls in the 0% and 15% bands.

You do not have to pick one. You can exchange part of the value and take the rest as cash, which is taxable boot up to your gain, as explained in what boot is in a 1031 exchange. Price both columns on sell and pay the tax vs a 1031 before the sale closes, because the choice disappears once proceeds reach your account.
