Capital Gains Tax on Rental Property: What Retirees Must Know

Selling a rental property you’ve owned for years — or decades — can generate a tax bill that surprises even financially sophisticated investors. The combination of federal capital gains tax, depreciation recapture, the Net Investment Income Tax, and state income tax can together consume 30% to 45% of your total gain, depending on your income level and where you live.

For retirees on fixed incomes who have counted on their real estate equity as a cornerstone of their retirement security, that tax bill can feel devastating — or at least deeply unfair. You built that equity over years of work, maintenance, and management. The government is entitled to a substantial share of it simply because you want to stop being a landlord?

The answer, unfortunately, is yes — unless you plan strategically. This article explains exactly how capital gains taxation works on rental property sales, what depreciation recapture is and why it matters, how state taxes amplify the federal burden, and what planning options exist to reduce, defer, or in some cases eliminate the tax.

Understanding What You’re Actually Taxed On

The first step in understanding your tax liability is calculating your taxable gain — which is not simply the difference between your sale price and what you paid for the property. The IRS uses adjusted cost basis, which accounts for the depreciation deductions you’ve taken (or should have taken) over your ownership period.

Step 1: Calculate Your Adjusted Cost Basis

Your original cost basis is generally what you paid for the property, plus certain closing costs and capital improvements you made during ownership.

From that figure, you subtract the accumulated depreciation you’ve claimed on the property. For residential rental property, the IRS requires depreciation over 27.5 years using the straight-line method. For commercial property, the period is 39 years.

Example:

• You purchased a rental property in 2005 for $300,000
• You made $50,000 in capital improvements over the years
• Your original adjusted basis: $350,000
• You’ve owned and depreciated the property for 21 years at $300,000 ÷ 27.5 = $10,909/year (on the structure — land is not depreciated)
• Total depreciation claimed: 21 × $10,909 = approximately $229,000
• Your current adjusted basis: $350,000 − $229,000 = $121,000

Step 2: Calculate Your Total Gain

If you’re selling that property for $900,000:

• Sale price: $900,000
• Adjusted basis: $121,000
• Total gain: $779,000

But this $779,000 gain is not all taxed the same way. It’s divided into two components with different tax rates:

The Two Components of Your Gain

Component 1: Long-Term Capital Gain

The portion of your gain attributable to actual price appreciation — what the property is worth today vs. your original purchase price plus improvements — is taxed as long-term capital gain (assuming you’ve owned it longer than one year, which most retiring investors have).

Federal long-term capital gains tax rates for 2025:

• 0% — for taxable income up to $47,025 (single) or $94,050 (married filing jointly)
• 15% — for most middle and upper-middle income taxpayers
• 20% — for taxable income above $518,900 (single) or $583,750 (married filing jointly)

Most retirees selling appreciated real estate will pay the 20% rate on this portion of their gain, particularly if the sale significantly increases their income for that year.

In our example: $779,000 total gain − $229,000 depreciation recapture = $550,000 subject to capital gains rates.

Component 2: Depreciation Recapture

When you’ve been deducting depreciation from your rental income each year — reducing your taxable income — the IRS wants that benefit back when you sell. This is called Section 1250 depreciation recapture, and it’s taxed at a maximum rate of 25% federally, regardless of your marginal income tax bracket.

Recapture applies to the accumulated depreciation you’ve claimed (or should have claimed — the IRS calculates recapture based on allowable depreciation, not just what was taken). In our example, that’s the $229,000 in accumulated depreciation.

In our example: $229,000 subject to depreciation recapture at 25% = $57,250 in federal recapture tax.

The Net Investment Income Tax (NIIT)

If your modified adjusted gross income (MAGI) exceeds $200,000 (single) or $250,000 (married filing jointly), an additional 3.8% Net Investment Income Tax applies to the lesser of your net investment income or the amount by which your MAGI exceeds the threshold.

For most retirees selling a highly appreciated property, the year of sale will push income well above these thresholds. The NIIT applies to both the capital gain component and, in most cases, the depreciation recapture as well.

In our example, assuming MAGI exceeds the threshold: $779,000 × 3.8% = approximately $29,600 in additional NIIT.

State Capital Gains Taxes

Federal taxes are only part of the picture. Most states tax capital gains as ordinary income, adding another layer of liability:

• California: 13.3% (maximum) — the highest in the nation
• New York: 10.9% (state) plus city tax in NYC
• New Jersey: 10.75%
• Oregon: 9.9%
• Minnesota: 9.85%
• Massachusetts: 5% (flat rate, but 8.5% for some gains)
• Texas, Florida, Nevada, Washington, Wyoming: No state income tax — a significant advantage for property owners in those states

For a California resident in our example, state taxes alone could add another $103,000+ to the bill. Many retirees from high-tax states have relocated specifically to reduce this exposure — though selling property still held in a high-tax state may trigger that state’s tax regardless of where you currently reside.

The Complete Tax Picture: A Worked Example

Let’s put the whole calculation together for our example investor — selling a rental property for $900,000 with a $121,000 adjusted basis:

Tax Component	Taxable Amount	Rate	Tax Owed
Long-term capital gains (federal)	$550,000	20%	$110,000
Depreciation recapture (federal)	$229,000	25%	$57,250
Net Investment Income Tax	$779,000	3.8%	$29,600
State capital gains (CA example)	$779,000	13.3%	$103,600
Total estimated tax			$300,450

That’s a $300,000+ tax bill on a $900,000 sale — roughly 33% of the gross sale price, and nearly 39% of the actual gain. For an investor who reinvests only $599,550 after taxes, the compound wealth impact of this tax event — compared to a tax-deferred strategy — is enormous.

Why Deferral Is So Powerful

The argument for deferring capital gains isn’t just about avoiding a large tax payment today. It’s about what that deferred amount can do in an income-generating investment over time.

Consider the difference between:

Scenario A: Taxable Sale

• Sale proceeds: $900,000
• Tax paid immediately: $300,450 (federal only, for simplicity)
• Amount available to invest: $599,550
• Invested at 5% annually for 10 years: $976,500

Scenario B: 1031 Exchange into DST

• Sale proceeds: $900,000
• Tax deferred: $0 paid now
• Amount available to invest: $900,000
• Invested at 5% annually for 10 years: $1,465,700
• Tax owed at end of 10 years: approximately $300,000 (potentially more due to additional DST appreciation)
• After-tax wealth: approximately $1,165,700

The difference: approximately $189,000 in additional wealth — simply from keeping the tax-deferred money invested rather than paying it to the IRS immediately. And this calculation doesn’t account for the stepped-up basis at death, which could eliminate the deferred tax entirely for heirs.

Tax Planning Strategies for Retiring Property Owners

1. The 1031 Exchange into a DST

The most widely used strategy for retiring real estate investors. By exchanging your property into a Delaware Statutory Trust (DST), you defer all federal and state capital gains taxes, depreciation recapture, and the NIIT. Your full equity continues working in a passive, income-generating investment. See our guide on [What Is a DST 1031 Exchange?] for a detailed explanation.

2. Installment Sale

Rather than receiving all proceeds at closing, you can structure the sale to receive payments over time — spreading the gain across multiple tax years. This can keep you in a lower tax bracket each year and avoid triggering the highest capital gains rates. However, installment sales require the buyer to finance the purchase from you (essentially making you the lender), which introduces credit risk and limits your flexibility.

3. Opportunity Zone Investment

Proceeds from a property sale can be invested into a Qualified Opportunity Zone Fund within 180 days to defer capital gains. The rules differ from a 1031 exchange — you pay tax on the original gain after a few years and invest only the gain, not the full proceeds. Opportunity Zone investments also carry risks related to the quality of the underlying investment. Consult a tax advisor for current rules.

4. Charitable Remainder Trust (CRT)

For investors with charitable intent, a CRT can be an effective structure. You transfer the property into the trust, the trust sells it without recognizing capital gains, and you receive an income stream for life (or a term of years). At your death, the remaining trust assets pass to charity. This eliminates the tax burden but permanently removes the asset from your estate.

5. Hold Until Death — Stepped-Up Basis

If you don’t need the liquidity and are not burdened by management, continuing to hold the property until death may allow your heirs to receive the asset at a stepped-up cost basis equal to fair market value at death — potentially eliminating the deferred capital gains tax entirely. This strategy works particularly well with DST investments, where there’s no active management required: you hold the DST interests, collect income, and your heirs inherit them with a stepped-up basis.

What the Tax Numbers Mean for Your Planning

Understanding your capital gains tax exposure is not a reason to panic — it’s a reason to plan. The tax consequences of selling a highly appreciated rental property can be managed, deferred, or in some cases eliminated with the right strategy. But that strategy must be put in place before the sale closes, not after.

If you’re considering selling investment real estate within the next one to three years, now is the time to:

• Calculate your approximate adjusted cost basis and embedded gain
• Understand your federal and state tax exposure
• Evaluate whether a 1031 exchange, installment sale, or other strategy is appropriate for your situation
• Engage a tax advisor who specializes in real estate transactions — general CPAs may not be familiar with the full range of options

The investors who preserve the most wealth are not the ones who got the highest sale price — they’re the ones who kept the most of what they received.
