What it costs at your volume
StanfordTax publishes its price, so the math is simple. Soraban quotes an annual license priced by return count.
| Returns a year | StanfordTax Premium ($18/return) | Soraban |
|---|---|---|
| 100 | $1,800 | Below the 250-return package minimum |
| 250 | $4,500 | Quoted license + $1,000–$4,500 one-time setup |
| 500 | $9,000 | Quoted license + $1,000–$4,500 one-time setup |
| 1,000 | $18,000 | Quoted license + $1,000–$4,500 one-time setup |
StanfordTax charges only for binders you use, and unused credits never expire. Its Enterprise tier ($25+ per return) is for firms with 5,000+ clients and starts with $10,000+ of implementation. Soraban says onboarding takes about 30 days and that ROI is strongest for firms handling 500+ returns.
Security and your WISP
Soraban states SOC 2 Type II with annual third-party audits, encryption, multi-factor authentication and full audit trails. StanfordTax shows an AICPA SOC 2 badge on its homepage, and its security page describes encryption in transit and at rest and MFA or Google SSO for production access; it does not say whether the report is Type I or Type II, so ask for it. Either way, record the vendor in your WISP vendor file and settle 7216 consent before client documents flow through a new tool.
Before you sign
- Confirm the tool integrates with the tax software you file in.
- Ask for the SOC 2 report and data-retention terms (IRS Pub 4557), and plan for 7216 consent.
- Get per-return or credit definitions in writing. Several r/taxpros users report credit costs changing mid-contract.
FAQ
Is StanfordTax cheaper than Soraban?
For most small firms, yes, and it is the only one of the two with a published price: $18 per return with no minimums, plus a free plan for 5 returns. Soraban is quoted, starts at 250 returns and adds a one-time $1,000–$4,500 setup fee, but it also covers workpapers, data entry into four tax engines and signed delivery.
Does Soraban enter data into my tax software?
Yes. Soraban Connect exports extracted data into UltraTax, Lacerte, Drake and CCH Axcess, with ProConnect listed as coming soon. Soraban reports 99.9–100% extraction accuracy across four seasons (vendor figure).
Can I try StanfordTax for free?
Yes. The free plan covers up to 5 returns with unlimited firm users and no credit card. Karbon customers can get up to five free organizers through the integration.
Which works with Karbon?
Both. StanfordTax has a native integration that runs organizers inside the Karbon for Clients portal with single sign-on. Soraban syncs client data-collection progress into Karbon.
Is Soraban right for a small firm?
Soraban sells packages from 250 returns and says it fits best at 500+ returns a year. Below that, a per-return organizer such as StanfordTax is usually the lighter option.
