Deferred Sales Trust (DST) — Complete Guide

Executive Summary

A Deferred Sales Trust (DST) is an estate and tax planning strategy that uses a trust combined with an installment sale under IRC §453 to defer capital gains tax on the sale of appreciated assets. Instead of selling an asset directly (triggering immediate capital gains), the asset owner transfers the property to a trust, which sells the asset and pays the original owner over time via an installment note — spreading the capital gains recognition over the life of the note.

Important Caveat: Deferred Sales Trusts exist in a gray area of tax law. Unlike SLATs, ILITs, and GRATs (which have explicit statutory authority), DSTs rely on the general installment sale rules of IRC §453 applied through a trust structure. They have drawn IRS scrutiny, and taxpayers should obtain qualified legal opinions before implementing a DST strategy.

What Is a Deferred Sales Trust?

A DST is essentially an installment sale to a trust — the asset owner sells their appreciated asset to an irrevocable trust in exchange for an installment note. The trust then sells the asset to the ultimate buyer. Because the original owner receives payments over time (rather than a lump sum), the capital gains tax is deferred and recognized proportionally with each installment payment.

Key Distinction: DSTs vs. Monetized Installment Sales

It is critical to distinguish legitimate Deferred Sales Trusts from abusive monetized installment sales, which the IRS has identified as a "transaction of interest" (Notice 2023-2) and included on its "Dirty Dozen" list of tax scams:

Legal Structure & Parties

Seller/Note Holder

The person who owns the appreciated asset. The seller:

• Transfers the asset to the trust
• Receives an installment note from the trust
• Recognizes capital gains proportionally as installment payments are received
• Cannot be the trustee or control the trust

Independent Trustee

The trustee of the DST is a critical role — they must be truly independent:

• Cannot be the seller, the seller's spouse, or any related party under IRC §267 or §318
• Should be a corporate trustee, professional fiduciary, or unrelated individual
• Must exercise independent judgment over trust investments and operations
• Must have genuine fiduciary duties (not merely a nominal role)

Buyer

The third party who ultimately purchases the appreciated asset from the trust at fair market value.

Installment Note

The promissory note issued by the trust to the seller. The note:

• Has a specified term (typically 10-30 years)
• Bears interest at no less than the Applicable Federal Rate (AFR) under IRC §7872
• May include provisions for early payment, balloon payments, or flexible payment schedules
• Must represent a genuine obligation (not a disguised sale or constructive receipt)

How It Works — Step by Step

Phase 1: Trust Formation and Asset Transfer

1. Create the DST — An irrevocable trust is formed with an independent trustee
2. Transfer the asset to the trust in exchange for an installment note
3. The installment sale is documented with proper note terms (AFR-compliant interest rate, payment schedule, maturity)

Phase 2: Asset Sale

1. The trust sells the asset to the third-party buyer at fair market value
2. The trust receives the full sale proceeds
3. Because the trust (not the seller) sells the asset, and the trust's basis in the asset equals the purchase price it "paid" (the installment note amount), the trust recognizes little or no gain on the sale

Phase 3: Investment and Installment Payments

1. The trust invests the proceeds — diversified portfolio, real estate, business ventures, etc.
2. The trust makes installment payments to the seller according to the note terms
3. Each installment payment has three components:

- Return of basis (tax-free)

- Capital gain (taxed at long-term capital gains rates)

- Interest income (taxed at ordinary income rates)

Phase 4: Tax Deferral

1. Capital gains are recognized proportionally with each installment payment — spread over the note term rather than all at once
2. The seller has effectively deferred the majority of the capital gains tax into future years

Tax Implications

IRC §453 — Installment Sale Rules

The DST strategy relies on the installment sale provisions of IRC §453, which allow taxpayers to defer gain recognition when they receive at least one payment after the year of sale. Key provisions:

• §453(a): Income from an installment sale is recognized in the year payments are received
• §453(b): An installment sale is any disposition where at least one payment is received after the close of the taxable year
• §453(d): Taxpayers may elect OUT of installment sale treatment (reporting all gain in year of sale)

Capital Gains Recognition

Each installment payment includes a proportional amount of capital gain, calculated as:

Example: $5 million asset with $1 million basis, 20-year note:

• Total gain: $4 million
• Gross profit percentage: $4M ÷ $5M = 80%
• Annual payment (principal only): $250,000
• Capital gain recognized: $250,000 × 80% = $200,000/year
• Tax at 23.8%: $47,600/year (vs. $952,000 all at once)

Interest Income (IRC §7872, §483)

The installment note must bear interest at no less than the Applicable Federal Rate (AFR):

• Short-term AFR: Notes with terms ≤ 3 years
• Mid-term AFR: Notes with terms > 3 years and ≤ 9 years
• Long-term AFR: Notes with terms > 9 years

Interest income is taxed at ordinary income rates (not capital gains rates).

IRC §453A — Interest Charge on Deferred Tax

For installment obligations with a face value exceeding $5 million, IRC §453A imposes an interest charge on the deferred tax liability. This provision is designed to prevent taxpayers from benefiting excessively from the time value of money on large deferred gains.

Depreciation Recapture (IRC §1250)

For depreciable real property, any gain attributable to depreciation recapture (unrecaptured §1250 gain) is taxed at 25% and must be recognized under the installment method's proportional rules.

Comparison with IRC §1031 Exchanges

When DSTs Are Superior to 1031 Exchanges

1. Sale of a business: 1031 does not apply to business assets (goodwill, personal property) post-TCJA
2. Sale of stock: 1031 specifically excludes stocks, bonds, and securities
3. Failed 1031 timing: When the 45/180-day deadlines cannot be met
4. Desire to diversify: When the seller wants investment diversification rather than another real property
5. Cryptocurrency: 1031 does not apply to crypto (excluded from "real property" definition)

Suitable Assets

IRS Scrutiny & Legal Risk

IRS Enforcement Posture

The IRS has increased scrutiny of installment sale trust arrangements in recent years:

• Notice 2023-2: The IRS identified certain monetized installment sale transactions as "transactions of interest" requiring disclosure (Form 8886)
• IRS Dirty Dozen: Monetized installment sales appeared on the IRS's annual list of tax scams
• Economic Substance Doctrine (Gregory v. Helvering, 293 U.S. 465 (1935)): Transactions lacking economic substance beyond tax avoidance may be disregarded

Key Legal Doctrines

How to Minimize IRS Risk

1. Obtain a qualified legal opinion from a recognized tax attorney (not the promoter's attorney)
2. Use a truly independent trustee with no connection to the seller
3. Demonstrate economic substance — the trust should have genuine investment activities
4. Document business purpose — reasons beyond tax deferral (diversification, estate planning, etc.)
5. Ensure the trust, not the seller, negotiates the sale — the trust should be the actual seller
6. File Form 8886 if the transaction is identified as a "transaction of interest"
7. Avoid monetized installment sale features — do NOT allow the seller to borrow against the installment note or receive the economic equivalent of the full proceeds

The Independent Trustee Requirement

Why Independence Matters

The trustee's independence is the linchpin of the entire DST structure. If the IRS can demonstrate that the seller controls the trustee (directly or indirectly), the installment sale treatment collapses:

• The seller would be treated as having constructive receipt of the full sale proceeds
• The entire capital gain would be recognized immediately
• Penalties and interest would apply

Who Qualifies as Independent?

• ✅ Corporate trust company (bank trust department, independent trust company)
• ✅ Unrelated professional fiduciary (attorney, CPA, financial advisor with no other relationship to seller)
• ❌ Seller's spouse or family member
• ❌ Seller's business partner or employee
• ❌ Entity controlled by the seller (directly or through attribution under IRC §267/§318)
• ❌ Promoter-affiliated entity (trustee companies owned or controlled by the DST promoter)

Investment of Trust Proceeds

After the trust sells the asset, the proceeds must be invested and managed by the independent trustee:

Investment Considerations

• Diversification: The trust should maintain a prudent, diversified investment portfolio
• Income generation: The trust must generate sufficient returns to make installment payments (principal + interest)
• Risk management: The trustee has fiduciary duties to manage risk appropriately
• Liquidity: Sufficient liquidity must be maintained to meet installment payment obligations

Common Investment Strategies

• Diversified equity/bond portfolio
• Commercial real estate (different from the sold property — achieves the diversification the seller sought)
• Private lending or structured notes
• Alternative investments (with appropriate due diligence)

Formation Requirements

Essential Steps

1. Engage qualified legal counsel — a tax attorney experienced in installment sale trusts (NOT the promoter's attorney)
2. Obtain a legal opinion letter — confirming the transaction qualifies for installment sale treatment under IRC §453
3. Draft the trust instrument — establishing the DST with an independent trustee
4. Execute the installment note — terms compliant with IRC §7872 (AFR interest rate), specified maturity, payment schedule
5. Transfer the asset to the trust with proper documentation
6. The trust sells the asset — the trust should be the actual seller on all sale documents
7. The trust invests the proceeds — under the trustee's independent management
8. File appropriate tax returns — Form 1041 for the trust; seller reports installment income on Form 6252
9. File Form 8886 if required under applicable IRS notices

Documentation Requirements

• Trust agreement
• Installment promissory note (with AFR-compliant terms)
• Third-party appraisal of the asset
• Legal opinion letter from independent tax counsel
• Sale documentation showing the trust as seller
• Trust investment policy statement
• Annual trustee reports

Estate Planning Integration

Death of the Note Holder

If the installment note holder (seller) dies before the note is fully paid:

• The remaining installment note is included in the seller's gross estate at fair market value
• The beneficiaries receive a stepped-up basis in the note under IRC §1014
• This means future installment payments received by the beneficiaries may have reduced or eliminated capital gains recognition (since the basis is stepped up to FMV)

Estate Planning Benefit: The DST provides a built-in estate planning advantage — if the note holder dies during the note term, the remaining gain may be effectively eliminated through basis step-up.

Integration with Other Trust Strategies

• DST + Dynasty Trust: Installment payments can be gifted to a dynasty trust (using annual exclusion or lifetime exemption)
• DST + SLAT: Installment income can fund SLAT contributions
• DST + ILIT: Installment income can fund life insurance premiums in an ILIT
• DST + Charitable Planning: Installment note can be structured with charitable remainder

Sample Provision Language

⚠️ DISCLAIMER: The following language is provided for educational and illustrative purposes only.

Installment Note Terms

Trustee Independence Clause

Common Pitfalls & Compliance

1. Constructive Receipt

The seller having access to or control over the sale proceeds before installment payments are made. Solution: Ensure complete seller separation from trust proceeds.

2. Inadequate Trustee Independence

Using a trustee who is related to or controlled by the seller. Solution: Use a truly independent corporate trustee.

3. Economic Substance Challenges

A DST with no purpose other than tax avoidance. Solution: Document legitimate business reasons (diversification, estate planning, risk management).

4. Below-AFR Interest Rate

Setting the installment note interest below the Applicable Federal Rate. Solution: Use the AFR rate applicable to the note term; document the rate source.

5. Failing to File Form 8886

Not disclosing the transaction if required under IRS notices. Solution: Review applicable IRS notices and file Form 8886 if the transaction qualifies as a "transaction of interest."

6. Promoter Reliance Without Independent Counsel

Relying solely on the DST promoter's legal analysis. Solution: Obtain an independent legal opinion from a qualified tax attorney who is not affiliated with the promoter.
