Outsourced Tax Preparation Cost: Pricing Models Explained | HelloBooks How outsourced tax preparation cost is usually structured: per return, per hour, dedicated staff or retainer, plus Circular 230 fee rules for your clients.
Vendors quote in different units, which makes proposals hard to compare. Put every quote on the same basis, the cost per finished, reviewed return, before you decide.

Smarter accounting for growing businesses| Item | How it is billed | What to watch |
|---|---|---|
| Per return | A fee per return, often tiered by form and complexity | Who decides the tier, and what re-work costs |
| Per hour | Hours logged by the provider | Time records you can audit; caps per file |
| Dedicated staff | A monthly fee for named full-time people | Idle time out of season; replacement terms |
| Retainer plus overage | A base block of work and a rate above it | How overage is measured in peak weeks |

A cheap draft that needs an hour of review is not cheap. Track your reviewer’s time on outsourced returns for the first few weeks and add it to the vendor fee; that total is the real unit cost.
Your own fee is governed by Circular 230. Section 10.27(a) says a practitioner may not charge an unconscionable fee in connection with any matter before the IRS, and 10.27(b) generally bars contingent fees for services in connection with IRS matters, with listed exceptions.
Outsourcing does not change those rules. It changes your margin, which is why the unit-cost exercise above matters.
The cheapest outsourced hour is the one you no longer need. When client books are kept current in HelloBooks, the provider starts from reconciled figures instead of a stack of statements, and fewer returns fall into the expensive tiers.
