Search "tax outsourcing for CPA firms" and you'll find software platforms with preparer networks, offshore staffing agencies, large BPO houses, and specialized preparation firms — all describing themselves identically. These twelve questions cut through the positioning. Ask them on the first call and take notes.
Capability
- 1. Who exactly prepares my returns? Named, dedicated team you can meet — or an anonymous pool? Continuity is where quality compounds.
- 2. What is their US tax training path? EA/CPA-track professionals with structured US tax education, or generalists learning on your clients?
- 3. Which return types are a specialization? If you need 1065s with special allocations or 990s, ask for that team specifically — and sample workpapers.
- 4. Which software do you work in daily? UltraTax, Drake, Lacerte, ProConnect, CCH Axcess — in your environment, not export-import gymnastics.
Security & Compliance
- 5. Walk me through your data environment. The answer should include: no local downloads, monitored sessions, device controls, encryption, access revocation.
- 6. Show me your audit evidence. SOC 2-type report scoped to the preparation environment; alignment with IRS Pub 4557 and GLBA.
- 7. How do you handle Section 7216? A documented consent workflow you can inspect — not "that's your problem" and not "don't worry about it."
Operations
- 8. What does your internal review look like before I see a return? Preparer self-review plus senior offshore review should be standard; ask what their review checklist contains.
- 9. What turnaround do you commit to — in writing? Overnight-to-48-hours for standard returns in season is the mature-provider norm.
- 10. How do you handle peak scaling? If February volume triples, whose problem is it? Listen for bench planning, not bravado.
Commercials
- 11. How is pricing structured? Fixed fee per return, scaled by complexity, quoted before the season — or an hourly meter you can't forecast? Ask what's not included.
- 12. What does month one look like? A pilot batch, workpaper-convention setup, and review-loop tuning — a provider without an onboarding methodology is planning to improvise on your clients.
Scoring What You Hear
Disqualify on security vagueness or 7216 hand-waving immediately. Among the rest, weigh continuity of team, entity-return depth, and pricing transparency most heavily — those three predict year-two satisfaction better than any demo.
GTPH answers all twelve in writing during evaluation — named Centers of Excellence, audited environments, a 7216 consent kit, committed turnarounds, and fixed per-return pricing — because a partner you'll trust with a season should welcome the hard questions.
