Activate when: preparing any return claiming EITC, CTC/ACTC/ODC, AOTC, or Head-of-Household status; onboarding a paid-preparer workflow; a reviewer says 'did we document due diligence?', 'are we 8867-covered?', 'EITC audit risk.'. Do NOT activate when: no refundable credit / HOH is claimed; the return is self-prepared with no paid preparer; the question is purely tax-law calculation (use a calc tool, not this).

Tax Prep — Refundable-Credit Due-Diligence (Form 8867)

Industry front door for checklist. This variant only adds domain triggers, a worked example, and industry packs. The reasoning engine is the parent checklist skill — run its Process. Nothing in the parent is modified or duplicated here. Not legal or tax advice. Guardrails reflect general IRS requirements; verify against the current Circular 230, Form 8867 instructions, and IRC §6695(g) before filing.

Activate when: preparing any return claiming EITC, CTC/ACTC/ODC, AOTC, or Head-of-Household status; onboarding a paid-preparer workflow; a reviewer says "did we document due diligence?", "are we 8867-covered?", "EITC audit risk." Do NOT activate when: no refundable credit / HOH is claimed; the return is self-prepared with no paid preparer; the question is purely tax-law calculation (use a calc tool, not this).

Why this variant

The parent checklist turns fuzzy "did we cover everything" into a verifiable gate. Paid-preparer due diligence under IRC §6695(g) is exactly that: a per-credit documented gate whose failure = $635/return (2024, indexed) penalty each. This maps the parent's gate discipline onto the four due-diligence requirements.

Domain inputs → parent's checklist gate

The four §6695(g) requirements become the checklist's items:

Completion & submission of Form 8867 for each covered credit.
Computation — worksheets/records showing each credit was computed correctly.
Knowledge — no info appears incorrect/inconsistent/incomplete; document questions asked.
Record retention — keep 8867, worksheets, and the docs relied on (3 years).

Worked example

Single filer, 2 qualifying children, Schedule C cash income near the EITC-max plateau. → Knowledge requirement triggers: document the reasonableness inquiry into cash receipts/expenses, residency of children (school/medical records seen), and relationship. Missing any = incomplete gate → do not file; return to intake.

Compliance anchors

IRC §6695(g) · Form 8867 & instructions · Circular 230 §10.22 (diligence) · Pub 4687 (paid preparer due diligence).

Packs

Solo preparer: minimum viable 8867 evidence folder per client.
Firm/season: reviewer sign-off gate before e-file release; sampling for QC.
Enterprise: tie gate to e-file blocker in software; log ruleId per return.

Red flags

Income sitting exactly at a credit's maximizing plateau.
Inconsistent dependents vs prior year with no life-event explanation.
Preparer "assumed" residency/relationship without any record.

Verification

8867 completed for every covered credit
Computation worksheets retained
Reasonableness inquiries documented (who/what/when)
Contemporaneous notes on any inconsistency resolved
Retention folder started (3-yr clock)
