The One Rule Above Any Audit Tool: Never Touch Client Funds

A corporate and multi-state tax advisory practice has one control that outranks everything else it might document: the firm never touches a client's refund. That's a professional conduct line under rules like IRS Circular 230, not a close management setting, and getting it wrong is a problem no software fixes, so check the current requirements with a tax attorney or your CPA.

With that boundary clear, FloQast and AuditBoard for corporate & multi-state tax advisory apply to the firm's own busy-season billing and control discipline, which is where the real reconciliation work sits.

Why Refund Handling Isn't a Reconciliation Problem

Preparers are prohibited from endorsing or depositing a client's refund check, and refund advance or bank product arrangements, where they exist, run through a separate, regulated banking relationship, not the firm's own operating account. If a firm's own bank account ever touches client refund money directly, that's a Circular 230 and, depending on the state, a licensing issue to resolve with a compliance attorney immediately, not a control to document and monitor going forward.

Once that boundary is confirmed clean, the firm's own financial reconciliations, revenue, WIP, security spend, are what FloQast or AuditBoard actually apply to.

Why Busy Season Revenue Recognition Gets Messy

Tax preparation revenue swings hard around filing deadlines, and firms that bill flat fees per return versus firms billing hourly for complex multi-state or advisory work need different recognition treatment. A flat-fee return is typically recognized when the work is substantially complete, while advisory hours recognize as worked, and mixing the two into one undifferentiated revenue number makes it hard to tell which service line is actually profitable.

Reconciling WIP and unbilled fees against actual hours or returns completed, every month, not just at the two annual filing deadlines, is close-process work, and it's exactly the kind of repeatable check close management software handles well during a season when staff bandwidth for anything beyond client work is thin.

The Security Six and What It Actually Requires

The IRS's Security Six is a set of recommended baseline controls, and the FTC Safeguards Rule, which covers tax preparers, requires a Written Information Security Plan that documents controls protecting client tax data, such as access controls, encryption, multi-factor authentication, and an incident response plan. That's a data security control framework, separate from financial statement controls, and it's a real, enforceable requirement for any firm that e-files returns.

While neither FloQast nor AuditBoard is built specifically for WISP compliance, a GRC platform can be a reasonable place to document and test the plan's required controls on a schedule once a firm is large enough that an IT consultant alone can't track it, since the underlying discipline, mapped requirements, tested and evidenced, is the same pattern either way.

A Worked Example: A Multi-State Engagement Billed Too Early

Picture a corporate client's multi-state nexus study that gets invoiced in full at project kickoff, before the state-by-state analysis work is actually complete, because cash flow during a slow month made the early invoice appealing. If the engagement stalls or scope changes partway through, the firm has recognized revenue for work it hasn't delivered, and unwinding that at year end is far messier than recognizing it correctly as the work progressed.

A reconciliation that ties recognized revenue to actual work completed, not invoice timing, catches this the same month it happens, protecting both the firm's own numbers and its standing if a client or reviewer ever questions the billing.

Sequencing the Decision

Confirm refund-handling and WISP compliance are airtight first, since those carry professional and regulatory risk no accounting software addresses. From there, if busy-season WIP and revenue recognition are the source of the most internal confusion, close management software is the higher-value fix, since it's the discipline protecting the firm's own numbers through the most volatile months of the year.

A formal GRC platform becomes worth it mainly once the firm is large enough to need documented, tested evidence across multiple compliance obligations at once, WISP, engagement quality, and financial controls, rather than tracking each informally.

Work through the priorities in this order:

  1. Confirm the firm never endorses, deposits or otherwise handles a client's refund, and resolve any exception with a compliance attorney immediately.
  2. Verify the Written Information Security Plan is current and covers access controls, encryption, multi-factor authentication and incident response.
  3. Monitor the firm's EFIN for unauthorized use, and require multi-factor authentication on tax preparation software before filing season starts.
  4. Separate flat-fee return revenue from hourly advisory revenue so each service line is recognized under its own timing.
  5. Move to close management software once busy-season WIP and revenue recognition cause the most internal confusion.

E-File Security Extends Beyond the Written Plan Itself

The IRS's e-file requirements go beyond having a written plan on file: firms are expected to monitor their EFIN for unauthorized use, since a compromised EFIN can be used to file fraudulent returns under the firm's own credentials, and to require multi-factor authentication on tax preparation software, since phishing attempts targeting preparers spike predictably every filing season.

Build a short recurring checklist, EFIN activity review, multi-factor authentication enforcement, staff phishing awareness, into the same cadence as the firm's other close and compliance tasks, rather than treating data security as a one-time setup task completed once and never revisited.

Executive Capability Standard

What Good Looks Like

A tax practice's operations are in good shape when refund handling never touches the firm's own accounts, the WISP's required controls are documented and tested on a schedule, and WIP and billed revenue tie to actual work completed every month, not just at the two annual filing deadlines.

Building The Capability (5-Stage Skill Ladder)

1. Learn:Confirm with a compliance attorney that no part of the firm's process ever touches client refund funds directly.
2. Do Manually:Document the firm's Written Information Security Plan against the IRS's required elements and note any gap.
3. Delegate:Assign someone other than the preparer on an engagement to review WIP and billed revenue against actual work completed each month.
4. Automate:Deploy FloQast to standardize busy-season WIP and revenue reconciliations, then add AuditBoard once the firm needs to test and evidence WISP and financial controls together.
5. Buy:Engage an IT security consultant to build or audit the firm's WISP before the next filing season, not during it.

Frequently Asked Questions

Can our firm ever deposit a client's refund into our own account?

No. Preparers are prohibited from endorsing or depositing a client's refund check under IRS ethics rules. If this has happened, even unintentionally, treat it as a compliance issue to resolve with an attorney immediately, not a process to adjust going forward.

What is a Written Information Security Plan, and does our firm need one?

A WISP is a documented data security plan required of any tax preparer who e-files returns, covering access controls, encryption, and incident response for client tax data. It's a real legal requirement for tax preparers under the FTC Safeguards Rule, and the IRS backs it with Publications 4557 and 5708, so it's separate from financial statement controls or SOX.

Should flat-fee and hourly advisory work be reconciled together?

Keep them separate. Flat-fee returns typically recognize when substantially complete, while hourly advisory work recognizes as worked, and combining them into one reconciliation obscures which service line is actually profitable during and after busy season.
