DST Depreciation Explained: How Pass-Through Deductions Improve Your Retirement Income

One of the most powerful — and least discussed — benefits of DST investing is the ongoing depreciation deduction that passes through to investors each year. For retiring real estate investors accustomed to direct ownership, this is a familiar concept. For those new to DSTs, it’s often a genuine surprise: the same tax shelter that made direct real estate ownership so attractive continues to work for you in a DST — without requiring you to manage a single tenant or call a single plumber.

This article explains how depreciation works inside a DST, how it flows through to your personal tax return, and how to think about its practical impact on your retirement income picture.

The Basic Concept: Depreciation in Real Estate

The IRS allows real estate investors to deduct a portion of a property’s cost each year as a “depreciation” expense — even if the property isn’t actually declining in value. It’s a recognition that physical assets wear out over time, and the tax code allows owners to account for this wear and tear.

For residential rental property, the IRS allows depreciation over 27.5 years. For commercial property, the period is 39 years. This means:

• A $2.75 million residential property can be depreciated at $100,000 per year
• A $3.9 million commercial property can be depreciated at $100,000 per year

This annual deduction reduces the property owner’s taxable income — even if the property is generating positive cash flow. It’s the primary reason rental real estate has historically been one of the most tax-efficient income-producing assets available.

How Depreciation Works in a DST

When you invest in a DST, you don’t own the property directly — you own a fractional beneficial interest in the trust. But the IRS treats your beneficial interest as direct ownership of real property for tax purposes (that’s the core of Revenue Ruling 2004-86). This means you receive your proportional share of the DST’s depreciation deductions on your personal tax return each year.

Example:

A DST owns a multifamily apartment complex purchased for $40 million. The building itself (excluding land) is valued at $30 million, which is depreciated over 27.5 years.

Annual depreciation on the building: $30,000,000 ÷ 27.5 = $1,090,909/year

If you own 2% of the DST, your share of annual depreciation is: $1,090,909 × 2% = $21,818/year

This $21,818 depreciation deduction appears on your Schedule K-1 each year. It reduces your taxable income — potentially sheltering a significant portion of your DST cash distributions from current taxation.

How Depreciation Interacts With DST Distributions

The practical impact of this on your retirement income is significant. Let’s walk through the math.

Scenario:

• You invest $600,000 in a DST targeting a 5.2% cash-on-cash return
• Annual cash distributions: $31,200
• Your proportional share of DST depreciation: $18,000/year

Without the depreciation shield:

• Taxable income: $31,200
• At 24% marginal rate: $7,488 in federal income tax
• Net after-tax cash: $23,712
• After-tax yield: ~3.95%

With the depreciation shield:

• Gross distributions: $31,200
• Less depreciation deduction: $18,000
• Net taxable income: $13,200
• At 24% marginal rate: $3,168 in federal income tax
• Net after-tax cash: $28,032
• After-tax yield: ~4.67%

The depreciation deduction improves your after-tax yield by nearly 0.72 percentage points — the equivalent of earning a meaningfully higher return on a fully taxable investment. Over 10 years of holding a $600,000 DST, that difference adds up to over $43,000 in additional after-tax income.

Cost Segregation: The Accelerated Depreciation Opportunity

Standard depreciation schedules use straight-line depreciation over 27.5 or 39 years. Many DST sponsors go further by engaging a cost segregation study on the property they acquire.

A cost segregation study reclassifies portions of the property into shorter depreciation categories:

• Personal property (appliances, carpeting, fixtures): 5-year or 7-year depreciation
• Land improvements (parking lots, sidewalks, landscaping): 15-year depreciation
• Building structure: Standard 27.5 or 39 years

By accelerating depreciation on these shorter-lived components, the sponsor can dramatically increase the depreciation deduction in the early years of the holding period — which flows through to investors as larger depreciation offsets in years 1 through 5.

Example impact of cost segregation:

On a $40 million multifamily acquisition, a cost segregation study might reclassify $8 million of the purchase price into 5-year and 15-year categories. In year one:

• Standard 27.5-year depreciation on the remaining $22 million: $800,000
• Accelerated depreciation on the $8 million of reclassified assets: $1,600,000+ (depending on bonus depreciation rules)
• Total year-one depreciation: $2,400,000+ vs. $1,090,909 without cost segregation

The front-loading of depreciation is most valuable in the early years of ownership — which is when you want maximum tax shelter on your distributions.

Bonus depreciation: Federal tax law has allowed “bonus depreciation” — an immediate first-year deduction of 100% of eligible property costs — at various levels over recent years. The rules have changed (and will continue to change) under various legislative cycles. DST sponsors who use cost segregation effectively take advantage of current bonus depreciation rules to maximize the pass-through benefit to investors.

Ask your DST advisor whether a specific offering has undergone a cost segregation study, and whether the projected depreciation pass-throughs in the K-1 are based on cost segregation or straight-line depreciation.

The Tax-Exempt Return-of-Capital Concept

There’s a related concept worth understanding: return of capital (ROC) on K-1s.

When your depreciation deductions exceed your taxable income from a DST, the excess creates a negative taxable income balance for tax purposes. This doesn’t mean you get a check from the IRS — it means that portion of your distribution is treated as a return of capital rather than ordinary income.

Return of capital is not taxed when received. Instead, it reduces your cost basis in the DST interest. When you eventually sell (or when the DST exits), your basis is lower — meaning a larger portion of your exit proceeds will be taxable at that time.

In practice, for investors using the step-up-at-death strategy, this basis reduction may be irrelevant: if your heirs receive the DST at a stepped-up basis at your death, the accumulated return of capital never becomes a tax event.

For investors who will eventually sell or exchange, the basis reduction means the depreciation shelter is a tax deferral (just like the 1031 exchange itself) — not a permanent elimination of tax liability.

Passive Activity Rules: An Important Limitation

Depreciation deductions from DSTs are passive losses — they can only be used to offset passive income. They generally cannot be used to offset wages, pension income, Social Security, or investment income (dividends and interest).

What this means in practice:

• DST depreciation deductions directly offset your DST distributions (which are also passive income) — this is the primary benefit and works fully.
• If your DST depreciation exceeds your DST distribution income, the excess is a suspended passive loss — it carries forward to future years and can be used when the DST exits (at which point all suspended passive losses become usable against the gain).

For most investors, the depreciation roughly matches or exceeds the distributions in the early years, effectively sheltering most or all of the distributions from current taxation. The specific ratio depends on the property type, leverage level, cost segregation status, and DST purchase price.

How to Read Your K-1 for Depreciation Information

Each year, you’ll receive a Schedule K-1 from the DST. The relevant lines for depreciation analysis:

• Box 2: Net rental real estate income (this is your share of the property’s taxable income before depreciation)
• Box 2 again, potentially negative: If depreciation exceeds income, this may show as a loss (suspended)
• Box 19 (Distributions): What was actually paid to you in cash
• Supplemental schedules: Most DSTs include detailed supplemental K-1 information showing the depreciation component separately

Compare Box 19 (cash you received) to the taxable income reported. The difference is the depreciation and other deduction effect. If you received $30,000 in distributions but only $12,000 is reported as taxable income, depreciation has sheltered $18,000 of your cash.

Your CPA should review your K-1 annually and explain the depreciation picture for your specific DST.

Depreciation Recapture at Exit: The Bill That Comes Due

The tax shelter from depreciation is not free. The deductions you’ve taken over the holding period reduce your cost basis. When the DST eventually exits (or when you sell your interest), the IRS “recaptures” the benefit of those deductions — taxing them at a 25% federal recapture rate.

This recapture is in addition to any capital gains tax on appreciation. It’s one of the significant components of the tax bill that builds up in a non-exchanged exit.

The recapture is why the 1031 exchange is so powerful: when you exchange out of a DST into a new replacement property, you defer the recapture along with the capital gains — carrying the basis reduction forward and continuing the tax deferral cycle.

For the step-up-at-death strategy, the stepped-up basis eliminates accumulated recapture just as it eliminates capital gains — again, another reason to consider the holding-at-death strategy for investors who can afford to keep the capital deployed.

Practical Implications for Retirement Income Planning

Understanding depreciation changes how you should compare DST income to other income sources. Here’s a framework:

When comparing DST distributions to bond interest: Bond interest is fully taxable as ordinary income. DST distributions are partially sheltered by depreciation. A 5.2% DST yield is often effectively superior to a 5.5% bond yield on an after-tax basis — especially for investors in the 22–32% marginal rate range.

When comparing to REIT dividends: REIT dividends include a “qualified business income deduction” component (up to 20% of REIT ordinary dividends may be deductible), but no direct depreciation pass-through. DSTs’ direct depreciation pass-through may provide a better shelter than REITs’ QBI deduction, depending on specific circumstances.

When comparing to direct rental income: Direct rental income also benefits from depreciation, but direct ownership adds active management obligations. A DST investor gets the depreciation benefit passively — which is the primary appeal for retiring landlords who want to eliminate the work but keep the tax efficiency.

The Bottom Line

DST depreciation pass-throughs are a real, meaningful financial benefit — not a footnote in a prospectus. For retiring investors comparing passive income options, the after-tax yield of DST distributions (net of depreciation shelter) is often materially superior to fully taxable alternatives at equivalent gross yields.

Understanding this benefit helps you make better decisions: evaluate DSTs on after-tax return, not just headline CoC yield. Ask sponsors about cost segregation. Work with a CPA who understands K-1 real estate income — not just W-2s and brokerage accounts.

The depreciation benefit is part of why retiring real estate investors who understand the full picture often find DSTs to be one of the most compelling income investments available to them in retirement. The tax code rewards real estate ownership — and DSTs let you capture that reward without the landlord work you’ve earned the right to leave behind.
