Outsourced preparation is sold two ways: a fixed fee per completed return, or a monthly rate for dedicated offshore staff. Neither is universally better — they map to different volume patterns — but you should walk into the conversation knowing the math for your firm.
Model 1: Fixed Fee Per Return
You pay a set price for each completed, review-ready return, tiered by complexity — a simple W-2 1040 at the low end; multi-state, K-1-heavy, or entity returns priced higher. Typical characteristics:
- Cost attaches to revenue: every fee you pay corresponds to a client invoice
- Zero off-season cost; capacity flexes with your actual volume
- Complexity tiers agreed up front, so December quoting is predictable
- Provider owns utilization risk and internal review before delivery
Best fit: the classic seasonal firm — heavy Feb–Apr and Sep–Oct volume, quiet summers.
Model 2: Dedicated Offshore Staff
You engage a named professional (or pod) full-time — effectively a remote employee at offshore economics, typically at a monthly rate a fraction of a US preparer's loaded cost. Characteristics:
- Fixed monthly cost regardless of volume — you own utilization
- Deep firm knowledge compounds: same person, your processes, year-round
- Handles mixed work: prep, bookkeeping, projections, extensions
- You direct the work day-to-day, like any staff member
Best fit: firms with genuine year-round workload or CAS practices.
The Math for a 1,000-Return Firm
Compare three scenarios for the same volume: an additional local hire (fully loaded $120K+, one preparer's seasonal output, turnover risk included); dedicated offshore staff (roughly a third of that cost, similar single-person throughput, you manage utilization); and per-return outsourcing (pay only per completed return — for most mixed books of 1040s and entities, total cost lands 40–60% below onshore preparation cost, with no idle months). Run your own numbers with last season's return mix; the pattern holds across most 500–5,000 return firms.
Hidden-Fee Traps to Check in Any Quote
- "Complexity re-rating" after preparation — insist tiers are defined by objective criteria up front
- Rush charges in peak season — the season is the engagement; peak turnaround belongs in the base SLA
- Onboarding or "setup" fees that repeat annually
- Hourly overflow clauses that quietly convert your fixed fee into a meter
The Hybrid Most Firms Reach
Year two often looks like: one dedicated staffer for year-round work, per-return capacity for the seasonal spike. GTPH offers both models on the same platform and prices per-return tiers in writing before the season — fixed means fixed.
