Identifying missing returns from IRS transcripts
What you see
No TC 150 on the Account transcript for a tax year that should have been filed; Verification of Non-Filing (VNF) or explicit “no return filed” language; Wage & Income transcript shows third-party income (W-2, 1099) but no matching return module.
What it means for the case
The IRS has not posted a taxpayer-filed return for that period. Resolution programs — installment agreements, OIC, CNC — generally require filing compliance first (see IRS Form 656-B and Form 9465 instructions). Quoting implementation before returns are filed often creates fee disputes.
What to investigate next
- Pull Wage & Income (RTVUE) for every year missing TC 150 — reconstruct income before scoping prep fees.
- Check adjacent years: a single missing year often indicates a multi-year compliance gap.
- Confirm whether the client filed but the return has not posted (recent e-file) vs. truly unfiled.
- Sequence work: prepare/file originals before promising OIC, IA, or CNC outcomes.
What this does not tell you
Transcripts do not show whether a return is in the mail, rejected by e-file, or stuck in processing — only what the IRS has posted. Client testimony still needs verification.

Identifying a Substitute for Return (SFR) on transcripts
What you see
TC 150 with description referencing substitute return / IRS-prepared return; assessment date long after the original due date; TC 971 with Action Code 141 (ASFR posted); TC 290/300 assessments with no taxpayer return on file; single filing status or missing credits when the client is married; balance higher than client expects with no recollection of filing.
What it means for the case
The IRS assessed tax under IRC §6020(b) using third-party information — typically without deductions, credits, or accurate filing status. SFR modules often block “clean” resolution until a taxpayer-filed original return is prepared (not Form 1040-X) and processed through audit reconsideration (IRM 4.13). Strategy must separate SFR years from filed years.
What to investigate next
- Compare Wage & Income transcript to the SFR assessment — identify inflated income and missing expenses.
- Determine whether TC 599 (return secured) posted after the SFR — return may be in process.
- Scope original return preparation and audit reconsideration before quoting OIC or IA on SFR balances.
- Document which liabilities are SFR-driven vs. taxpayer-filed — fee and timeline differ materially.
What this does not tell you
Transcripts rarely print the words “Substitute for Return” in one obvious field. Pattern recognition across TC 150 timing, AC 141, and W&I mismatch is required — not a single code lookup.

CSED and collection statute information from transcripts
What you see
TC 150 (and TC 290/300) assessment dates; TC 599 (statute expiration / write-off in some contexts); TC 520 (bankruptcy/litigation hold); TC 694/480 (OIC pending); TC 971 with CDP-related action codes; IRS may print “CSED” on account transcripts for some periods.
What it means for the case
Each assessment starts a collection window (generally 10 years from assessment per IRC §6502, adjusted for tolling). Years nearing expiration change whether PPIA, wait-and-monitor, or OIC math favors the client. OIC pending tolls the statute; CNC generally does not.
What to investigate next
- Build a per-year CSED worksheet — base date plus documented tolling (OIC, bankruptcy, CDP, out-of-country).
- Compare shortest CSEDs to total balance — PPIA-to-expiration may beat OIC when RCP is low but time is short.
- Verify IRS-printed CSED against your worksheet; call Practitioner Priority Service when dates disagree.
- Flag years where collection may expire before a proposed IA would finish paying.
What this does not tell you
Not every tolling event is obvious on a single-year transcript. Cross-year OIC history, prior CDP, and bankruptcy discharges require a multi-year read. IRS.gov notes you may contact the IRS to verify CSED when transcript dates are unclear.

Penalties shown on IRS transcripts
What you see
TC 160/166 (failure-to-file penalty assessed); TC 276 (failure-to-pay); TC 270/271/276 combinations; TC 291/301 abatements reducing prior assessments; penalty lines in the balance breakdown on Account transcripts.
What it means for the case
Penalties can exceed the underlying tax. Abatement (FTA, reasonable cause, statutory exception) may be viable before or alongside IA/OIC — but transcript lines show what posted, not whether abatement will succeed.
What to investigate next
- Separate assessed tax, penalties, and interest per year — clients rarely understand the split.
- Check clean three-year history for First Time Abatement (IRM 20.1.1) before promising reasonable-cause work.
- Note whether penalties are still accruing (FTP) vs. fixed (FTF on assessed modules).
- Sequence: compliance → penalty review → program selection — not the reverse.
What this does not tell you
Transcripts do not contain reasonable-cause narrative, Form 843 arguments, or penalty abatement approval odds. They show whether penalties posted and whether abatement credits (TC 271/291) already hit the module.

Collection activity on transcripts — what to investigate next
What you see
TC 582 (NFTL filed); TC 668 (levy); TC 670 (payments); TC 470/530 (holds/CNC); TC 971 AC 641 (passport certification) or AC 643 (decertification); TC 971 AC 086 (IA established).
What it means for the case
Active enforcement (levy, imminent levy) changes urgency and sequencing — release or alternative collection arrangement often precedes long-term resolution design. Lien filing affects asset and OIC equity calculations even when no levy is active.
What to investigate next
- If TC 668 is present: confirm source (wage vs. bank), whether IA/CNC will release, and CDP rights.
- Map lien filing dates to asset events (sale, refinance) before advising on OIC or IA.
- Check passport certification (AC 641) when balance exceeds seriously-delinquent thresholds.
- Document collection posture in writing before the client meeting — surprises destroy trust.
What this does not tell you
Transcripts do not show every IRS collection decision in narrative form. Revenue Officer assignment, unposted notices, and pending levy sources may require PPS contact or notice review.

Filing compliance before IRS resolution options
What you see
Mix of filed (TC 150), SFR (TC 150 + ASFR indicators), and unfiled modules; missing estimated tax payment history on open years; business modules with employment tax deposit gaps (separate MFT).
What it means for the case
IRS processability rules require filed returns (and current estimates/deposits) before OIC consideration (Form 656-B). Form 9465 similarly denies IA when required returns are unfiled. Compliance work is not optional “prep” — it is the gate to every major program.
What to investigate next
- List every module: filed / SFR / unfiled / in process — before discussing program fit.
- Confirm current-year estimated payments and business deposits if self-employed or employer.
- Price compliance (prep + filing) separately from resolution implementation when years are open.
- Re-pull transcripts after filing posts — strategy changes when TC 150 replaces SFR assessments.
What this does not tell you
Transcripts do not prove the client will stay compliant after engagement. Post-resolution compliance terms (especially OIC five-year rule) require intake and monitoring beyond the transcript read.

Transcripts before evaluating an installment agreement
What you see
Total balance by year; TC 971 AC 086 if IA already established; prior IA default indicators; CSED dates vs. proposed payment horizon; TC 668 if levy is active.
What it means for the case
Streamlined IA (balances under IRS thresholds) may need little disclosure, but multi-year debt with short CSEDs may favor PPIA — pay what disposable income allows until statutes expire. Active levy usually requires establishing IA or CNC to release.
What to investigate next
- Sum balances and compare to streamlined IA thresholds (verify current IRS guidance).
- Calculate whether full-pay IA completes before each year’s CSED; if not, model PPIA.
- Check for open exams (TC 420) — balance may still move.
- Confirm filing compliance on all modules included in the IA request.
What this does not tell you
Disposable income and allowable expenses live on Form 433 — transcripts show liabilities and posting history, not whether the client can afford the payment.

Transcripts before evaluating an Offer in Compromise
What you see
Open TC 420/424 (exam); TC 694/480 (prior or pending OIC); TC 520 (bankruptcy); compliance gaps; assessed balances and penalty composition; CSED timeline vs. OIC investigation length (often 12–24 months).
What it means for the case
OIC is processability + RCP math. Transcripts answer the first half: Is the case structurally eligible? Is an exam open? Is compliance current? Will OIC tolling help or hurt given CSED? RCP still requires 433-level financials.
What to investigate next
- Clear exam and compliance blockers before scoping OIC fees.
- Model CSED tolling if OIC is rejected — a failed OIC on a near-expiration year can be costly.
- Compare total RCP estimate (once intake is done) to balance — if RCP ≥ balance, IA may be the honest answer.
- Read prior OIC history on transcript before re-filing.
What this does not tell you
Asset equity, household expenses, and future income are not on Account transcripts. IRS OIC Pre-Qualifier uses financial inputs transcripts cannot supply.

What balances across tax periods mean for resolution planning
What you see
Different assessed amounts, penalty ratios, and CSED dates per year; some years at TC 599 (uncollectible by statute) while others remain open; mixed SFR and filed modules.
What it means for the case
Resolution is rarely one program for all years. PPIA may zero out short-CSED years while longer modules pay down; OIC must include all eligible liabilities; penalty-heavy years may be better abatement candidates than high-tax years.
What to investigate next
- Build a year-by-year matrix: assessed tax | penalties | interest | CSED | filing status | enforcement flags.
- Rank years by strategic priority (levy year first, expiring CSED second, etc.).
- Avoid quoting a single monthly payment before the matrix exists — clients hear certainty you do not yet have.
- Tie the matrix to a written Strategy report the client can keep.
What this does not tell you
Transcripts do not tell you which program the client will accept emotionally or which fees the firm should charge — only what the IRS has posted and what programs are structurally available.

What IRS transcripts tell you about resolving a tax case
What you see
The full multi-year Account and Wage & Income picture: assessments, compliance posture, enforcement, statutes, and payment history.
What it means for the case
Transcripts answer: What does the IRS know? What is enforced? What time is left? They do not alone answer: What should we do? — that requires financial profile, client circumstances, and professional judgment — but they constrain the option set.
What to investigate next
- Complete the transcript read (compliance → CSED → enforcement → penalties).
- Gather 433-grade financials and client facts transcripts cannot show.
- Rank programs (IA, PPIA, CNC, OIC, penalty relief, compliance prep) with rationale tied to evidence.
- Document findings in Discovery, then Strategy — so the file survives staff turnover and fee disputes.
What this does not tell you
Transcripts are Tier IRS evidence — authoritative for balances and posting history, not for ability-to-pay (Tier 433) or client story (Tier client narrative). Keep tiers separate so contradictions surface.
