The return is marked complete. Your reviewer opens it and finds an unexplained difference from last year, two missing workpapers, and a question about a partnership K-1 that nobody raised with the client. Now the return is back in the queue.
That is how a firm can outsource preparation and still end up doing much of the work twice.
Offshoring itself is hardly unusual. Of the more than 1,100 accounting firms in the AICPA’s 2023 National MAP Survey, about 25% reported using offshore workers, according to the Journal of Accountancy.
But adoption tells us little about execution. Tax preparation outsourcing works differently across firms and providers. Some problems come from weak provider skills. Others develop because the firm never agreed on how work would be assigned, checked, or returned.
Here are the assumptions worth questioning before another tax season makes those gaps expensive.
A tax manager sends a batch of Form 1040 returns to an offshore provider on Monday. On Thursday, the status report still says “in progress.” Which returns are waiting on documents? Has anyone started the more complicated files? Who is reviewing the drafts?
If the only way to find out is to email an account manager and wait for an answer, the firm has a visibility problem.
This is what people often mean by black-box outsourcing. Work goes out, and a finished file is expected to come back. Everything in between is difficult to see. When a return is late or needs correction, the domestic reviewer has to reconstruct what happened.
That doesn’t mean every project-based outsourcing arrangement is opaque. Nor does employing a dedicated offshore professional automatically create transparency. The difference is how responsibility and progress are recorded. The CPA firm needs access to that information while the return is moving, when there’s still time to act on it.
A manager should be able to answer a few basic questions without chasing people: who has the return, what is holding it up, who checked it, and what still needs a decision.
Return stage | Information the manager needs |
Assigned | Named preparer, scope, expected handoff |
Waiting on client | Missing documents or unanswered questions |
In review | Reviewer, comments, items sent for correction |
Ready for approval | Checks completed and issues still open |
Credfino’s Canopy workflow playbook offers a practical example. A request can move from “With the client” to “Needs Review,” then be marked “Completed” after someone checks the response. The operations manager assigns a preparer, and new questions uncovered during preparation are tracked as additional-information requests.
That record matters when someone else takes over the file. They can see what was requested, what came back, and whether the answer was checked.
A status label alone won’t fix weak work. But when tasks, questions, and review ownership are visible, a tax manager can intervene before a missed document turns into a last-minute filing problem.
A client uploads W-2s, a brokerage statement, and last year’s return. The offshore preparer starts working. Two days later, someone notices a partnership interest mentioned on the prior-year return but no current-year Schedule K-1.
Now the team has to ask the client for the missing form, reopen the workpapers, and revisit whatever calculations the new information affects. The reviewer may need to look at the file again too. If the missing document changes an earlier assumption, the notes and draft need updating as well.
It’s easy to blame the preparer for the delay. Sometimes the preparer should have spotted the gap sooner. But the assignment itself may have been released before anyone checked whether the source documents were complete.
The same issue can be harder to detect in business returns. Prior-year elections, shareholder basis records, ownership changes, or state apportionment details may not be obvious from the current-year upload.
In a reliable outsourced tax preparation process, someone owns that completeness check. The preparer also needs a way to flag missing information during preparation, with the question recorded against the return rather than lost in an email chain.
Credfino’s Canopy playbook describes both a final document check before assignment and an open-items request when new questions arise mid-preparation.
A return can move backward in the workflow. That’s normal. The operations team should know who is waiting for the answer and when the file can return to preparation, without restarting the entire handoff.
Suppose Provider A has the lowest per-return quote. Its drafts arrive on time, but the schedules are inconsistently labeled and the reviewer must repeatedly ask how amounts were calculated.
Provider B charges more. Its files include reconciled workpapers, explanations of unusual items, and a list of client questions that still need answers.
Which is cheaper for your firm?
The quote won’t settle it. You also have to consider the time your staff spends reviewing, correcting, coordinating, and sometimes preparing parts of the return again. Those hours matter most when your senior tax staff are already stretched. If a partner ends up resolving the same basic documentation problems across dozens of files, the initial price advantage can disappear quickly.
The Journal of Accountancy’s guidance on outsourcing and professional liability specifically recommends assessing how much direction, monitoring, and review an external provider will require.
That is why a fair comparison of tax preparation outsourcing cost starts with the work delivered, not only the number on an invoice.
Ask providers for a redacted, review-ready sample. Check the workpapers, notes, and error-correction process. Find out whether you will have the same preparer across recurring engagements or whether work moves between unfamiliar staff. Ask which corrections are included in the fee and who resolves questions when the original preparer isn’t available.
Low cost isn’t proof of weak quality, just as a higher rate isn’t proof of expertise. What matters is how reliably the provider returns work your own team can use.
Your offshore team sends eight Form 1040 drafts on Friday. By Monday, your manager has reviewed only three. One return has unexplained differences in investment income, another is missing basis support, and a third has an unresolved question about estimated payments. Each needs a follow-up before the manager can approve it.
The preparation backlog is smaller. The review queue is growing.
This is a common planning mistake in tax preparation outsourcing: counting returns prepared without checking how much work remains after preparation. A draft may be technically complete in the software while still requiring substantial investigation by the person reviewing it.
That needs an answer before the first batch is assigned. Who checks the source documents against the return? Who reviews the calculations and tax positions? If the reviewer finds an error, does it go back to the original preparer, or does someone in the U.S. correct it to save time?
Either approach may work, but the process shouldn’t be improvised for every return.
A useful outsourced tax return review package includes the draft return, supporting workpapers, reconciliations, and a list of unresolved matters. The reviewer should be able to follow the preparer’s reasoning rather than recreate it.
Credfino’s six-eyes approach, for example, assigns preparation, checking, and senior review to three roles. The exact arrangement can differ by engagement, and the CPA firm must still oversee the work it delivers. As the Journal of Accountancy explains, outsourcing does not transfer the firm’s ultimate responsibility for client services.
The measure worth watching is reviewer effort per approved return, alongside the number of drafts completed. If the former keeps rising, additional preparation capacity may only move the bottleneck.
It’s tempting to divide the work by location: routine Form 1040s offshore, anything complicated in-house. That may be sensible when a firm is just starting. It becomes limiting if the rule never changes, regardless of the team’s experience.
A return’s form number tells you surprisingly little about how difficult it will be. One Form 1040 might contain only wages and interest. Another includes several Schedule K-1s, rental activities, basis limitations, and income from multiple states. Business returns vary just as widely.
The reverse mistake is equally risky. A provider says its team handles Forms 1065 and 1120-S, and the firm assumes every assigned preparer can work through complicated allocations or shareholder basis issues without support.
Before assigning complex work, ask about the individual offshore tax preparer’s experience with those issues. Who will review the return? Can the preparer explain how they would handle an unfamiliar tax position? What would trigger escalation to a senior professional?
Qualified offshore staff may be able to prepare or review complex returns. Others will need more training or a narrower scope. That’s a staffing decision, not a geographic one.
A simple, medium, and complex return-classification system helps here. Match the preparer and reviewer to the work, then broaden assignments when their performance supports it.
Imagine an offshore preparer finds a mismatch between the trial balance and the numbers supplied for an S corporation return. They send a question to the U.S. tax manager at the end of their shift. The manager sees it the next morning, but the message doesn’t say which adjustment was attempted or what decision is needed.
Another day passes while both sides clarify the question.
The time-zone gap mattered, but so did the handoff. A short message with the relevant workpaper, the discrepancy, and a proposed next step could have helped the manager respond without another round of emails.
For an offshore tax preparation team, agree on where questions belong, who can answer them, and which issues should be escalated rather than left until the next scheduled meeting. An open-items log inside the practice management system is more useful than scattering decisions across email and chat.
Overlapping working hours are helpful for discussions that require judgment. Routine updates can happen asynchronously. Both need clear ownership.
Communication skills should also be evaluated person by person. Ask a prospective preparer to explain a tax-workpaper issue or write a short client-information request. That reveals more about their ability to work with your firm than assumptions about a country or its time zone.
Questions need to reach the right person with enough context to move work forward.
A tax manager announces that Form 1040 preparation will move offshore next season. The partners have been discussing capacity for months. Associates are left wondering whether fewer preparation assignments will mean fewer chances to learn, or even fewer jobs.
Then the first outsourced drafts arrive with missing workpapers. Instead of getting time back, the domestic team is correcting them. It’s easy to see how resentment builds.
This is why offshore staffing for CPA firms needs a conversation with the people who will work alongside the new team. Explain which returns are moving, who will train the preparers, and how review comments will be handled. Invite your senior accountants to help define what a complete workpaper package should look like.
The Journal of Accountancy recommends involving onshore staff in shaping offshore roles and the way teams collaborate. That input matters because reviewers know which mistakes consume time and which client details are easily missed.
There’s a longer-term issue, too. Junior accountants learn to spot problems partly by preparing returns themselves. If all routine preparation disappears from their work, where will they build the judgment needed to review complicated returns later?
Keep suitable preparation assignments, guided reviews, and technical discussions in the domestic training plan. Offshore support may free experienced staff for planning and client work, but that benefit shouldn’t come at the expense of developing the next generation of reviewers.
A staffing decision changes how the whole tax team works. Treat it that way.
A firm signs a contract with an offshore provider, sends over client documents, and assumes the provider has handled the compliance details.
But the provider’s contract doesn’t replace the CPA firm’s obligations.
Consider IRS Section 7216. For the typical arrangement in which a U.S. preparer gives tax return information to an overseas preparer, the firm must obtain applicable taxpayer consent before that disclosure. The Form 1040-series consent requirements are especially specific. A signed engagement letter isn’t automatically a compliant overseas disclosure consent.
For individual returns, Social Security number disclosure has additional restrictions, including masking requirements unless the applicable safeguard exception is satisfied. The IRS consent guidance explains these conditions.
The location of the server doesn’t settle the question, either. The Treasury regulations describe an offshore contractor viewing information stored on a U.S. server, without downloading or printing it. That still counts as disclosure outside the United States.
Security needs its own checks. Virtual desktops and restricted access can reduce exposure, but they don’t prove that a provider’s safeguards are adequate. Who authorizes access? Is multi-factor authentication enforced? Can staff copy data? What happens when someone leaves the team or a security incident occurs?
Under the FTC Safeguards Rule, covered firms must select and oversee service providers with appropriate protections, address safeguards in contracts, and reassess them over time.
For tax preparation outsourcing compliance, responsibility must be assigned explicitly. Decide who obtains and records consent, who approves system access, and who reviews security evidence before the first return is released offshore.
The mistake is believing a reputable provider makes those decisions unnecessary.
A CPA firm waits until March to bring in an offshore team and immediately sends over dozens of returns. The new preparers know U.S. tax software, but not the firm’s workpaper format, recurring client issues, or how its reviewers prefer questions documented.
By the time those differences show up, deadlines are close and nobody has much room to adjust.
Start with a pilot that your reviewers can handle closely.
Choose a limited set of returns with known complexity. Agree on what a review-ready package contains and have a named reviewer examine each draft. Record the issues that come back. Was an error technical, a missing document, or simply an instruction the preparer never received?
For an offshore tax preparation pilot, compare first-pass quality, review hours, open-item resolution, and end-to-end turnaround against your existing process. A fast draft that sits in corrections for three days isn’t a fast return.
Give the provider the results and see whether the same issues disappear in the next batch. If the work improves, expand gradually. If it doesn’t, revise the instructions, adjust staffing, or reconsider the arrangement.
You learn more from a small batch you can review properly than from a large one you barely have time to check.
A provider cannot fix a tax workflow your firm has never defined. But good procedures also need capable people and someone accountable when work goes wrong.
Before increasing offshore volume, look at what comes back. Are the workpapers usable? Are unanswered questions visible? Is reviewer effort improving from batch to batch?
Those answers tell you more than a count of completed drafts.
Credfino helps CPA firms build offshore tax teams around their software, review standards, and capacity needs. Let’s schedule a call and discuss with our team about your workflow.
Sometimes. The benefit comes from complete, review-ready files, not faster drafts. Compare hours spent reviewing and correcting similar returns prepared internally to see whether outsourcing tax preparation actually saves time.
The CPA firm remains accountable for its professional services. Agree who corrects errors, supervises outsourced work, and handles signing and filing responsibilities..
Yes, when offshore tax preparers have relevant U.S. tax experience and review support. Test their knowledge of partnership allocations, shareholder basis, and multistate filings instead of relying on a provider’s general assurances.
Generally, consent is required before a U.S. preparer discloses taxpayer return information to an overseas preparer. Form 1040-series returns have specific consent requirements, including additional rules for Social Security numbers.
Require named preparers and reviewers, return statuses, documented questions, and escalation rules. Your manager should know who owns a delayed file and what’s preventing progress without chasing updates.
It can if junior staff lose meaningful preparation experience. Preserve selected preparation assignments, guided reviews, and technical discussions so they still develop the judgment they’ll need when reviewing more complicated returns.
The best offshore accounting model for staff development is usually the one that lets good people stay close enough to the firm for learning to accumulate.
Dedicated and consistently assigned staffing generally gives that training the most room to grow.
Other models still have their place. The real question is whether what your firm teaches today will still make the team better tomorrow.
