Frequently asked

The questions firms ask before signing.

Frequently asked questions

  • What's a typical turnaround time during tax season?
    For business returns, we target 5 working days from complete PBC list to draft. Individual returns, 2–3 working days. We confirm a per-engagement SLA in the scoping call before any work begins.
  • Who actually reviews the return before it reaches my firm?
    Every return is self-reviewed by a US-trained reviewer on our team before it lands in your queue. We are not a data-entry shop — your review should be a final pass, not a reconstruction.
  • How do you handle data security?
    We work in a secure VDI with no local data download, SOC 2-aligned access controls, and SSO + MFA. ISO 27001 certification is in process. We sign your confidentiality agreement before any data exchange.
  • Which tax software do you support?
    UltraTax CS, Lacerte, Drake Tax, CCH ProSystem fx, and GoSystem Tax. We work in your firm’s environment — no vendor switching required.
  • Can you handle multi-state filings and nexus analysis?
    Yes — multi-state apportionment is part of our default scope. We document nexus positions and surface state-level surprises before they become notices.
  • What does the engagement cost?
    Pricing is per-return for tax work; we quote at the entity level after the scoping call. Fixed-fee pilots run on a single return before any term commitment.
