DST IRS Examination — What an Audit Actually Looks Like
If the IRS selects your Deferred Sales Trust for examination, here's what happens. This isn't theoretical — it's the standard playbook for trust-based deferral structures the IRS scrutinizes.
Buyer cash → Assignment Co. → A-rated carrier → You, on schedule
The §453 Structured Installment Sale audit playbook is materially different and substantially simpler. We'll cover both.
DST examination — typical sequence
1. Letter 2205-A: Notice of Examination
You receive a letter from your local IRS office (Examination Group) identifying the tax year(s) under examination. For DSTs, the trust's tax return (Form 1041) is typically examined alongside your individual return (Form 1040 with attached Form 6252 reporting your installment payments).
2. Information Document Request (IDR Form 4564)
The IRS issues IDRs requesting:
- Trust agreement and all amendments
- Trustee compensation history
- Trust bank statements and investment records
- Loan agreements (if any) between trust and seller or seller's family
- All correspondence with the DST promoter
- Original PSA / purchase and sale agreement
- Allocation schedule for §1245 / §1250 recapture
- Beneficiary information and distribution history
3. On-site or virtual examination
The IRS revenue agent reviews documents and interviews:
- The trustee (specific questions about independence)
- The seller (specific questions about ongoing control)
- The promoter (sometimes)
4. Substance-over-form analysis
The agent applies:
- Sham trust doctrine (was the trust a bona fide separate taxpayer?)
- Assignment of income (did seller effectively assign income to the trust?)
- Step transaction (collapse the seller-trust-buyer chain?)
- Economic substance (did the trust have non-tax business purpose?)
5. Outcome
- Sustained: trust collapsed, installment method voided, all gain accelerated to year of sale, plus interest from original sale date, plus possible accuracy penalty
- Settled: taxpayer agrees to partial recharacterization to avoid Tax Court litigation
- Closed without adjustment: rare for DSTs in current examination environment
DST examination timeline
Total exposure: 2-5 years of audit defense costs and uncertainty.
§453 Structured Installment Sale examination — different playbook
If the IRS examines your §453 SIS, the audit follows the standard installment-sale audit pattern:
Standard installment-sale IDR
- PSA / closing documents
- Form 6252 calculation backup (gross profit ratio, contract price)
- Annual payment received documentation
- Verification of assignment to qualified assignment company
- Carrier annuity contract
Standard analysis
Revenue agent verifies:
- Sale was a bona fide installment sale (yes)
- Gross profit ratio correctly calculated (verifiable arithmetic)
- Payments correctly reported each year (matches 1099 from carrier)
- Assignment company is a qualified party (regulated subsidiary of major carrier — yes by definition)
Outcome
Standard installment-sale audit — usually closes without adjustment because the §453 mechanic is straightforward and well-settled. Total time: typically 3-9 months.

Frequently asked
Q: How likely is my DST to be examined? A: Selection is partly random, partly based on filing characteristics. The IRS has been examining DSTs more frequently since approximately 2014. Specific selection rates are not public.
Q: If I already have a DST, what should I do? A: Talk to independent tax counsel (not your DST promoter) about your specific facts. Audit risk varies by structure.
Q: Does the §453 SIS have any audit complications? A: Standard installment-sale audits happen, but they're arithmetic exercises — no sham-trust theory, no assignment-of-income theory.
