Before you work out which seats can move, find out which ones cannot. IRS Publication 3112 requires everyone listed as a Principal or Responsible Official on a firm's e-file application to be a United States citizen or an alien lawfully admitted for permanent residence.
That is one of the few parts of how to build an offshore accounting team that a rule settles for you. The rest is design, and most of it happens before anyone is hired: how many preparers your review chain can carry, which role you fill second, who the team reports to, and what has to be true before you add the next person.
How to Build an Offshore Accounting Team: The Short Answer
Build around your review capacity, then add seats in the order that keeps every file reviewable.
Six decisions, in this order, because each one narrows the one after it:
- Name the work. One work type, in one software, for one stretch of the year. A team is hired against a specification, so the scope gets written before the job description does.
- Measure what review costs you. Your own reviewer's hours per file set the ceiling on how many preparers you can carry, whoever employs them.
- Settle the compliance sequence. Client consent for disclosure outside the United States, your security diligence, and the contract all come before any client data moves, and none of them apply retroactively.
- Fill one seat. One named preparer, on real representative work, graded by the reviewer who would otherwise be fixing it in April.
- Pick the shape. Decide whether the team sits inside your client groups or in a shared pool while the choice is still cheap to make.
- Add each next role on a trigger. Every addition should answer a constraint you have measured, not a headcount you imagined.
Size the Team From Your Review Capacity, Not Your Backlog
The number of offshore preparers your firm can carry is set by one number you already own: the hours your reviewer spends per file. That review is the constraint is not news. Converting it into a seat count is the part firms skip, and it is the whole of this section.
So the sizing question is a ratio, not a rate. Work out how many files your reviewer can clear in a week at the review time offshore work actually costs you in its first season, then work backwards to the preparer hours those files consume.
``` Illustration, stated inputs only
Work type individual returns, one firm's own mix Offshore preparation time 6.0 hrs per return (your number, measured) Firm review time, in-house 0.8 hrs per return (your number, last season) Firm review time, offshore 1.5 hrs per return (your number, season one) Reviewer hours available 18 hrs per week (your number, after client work and calls) Usable preparer hours per seat 35 hrs per week (your number, after training, queries, leave)
Returns the reviewer clears 18 / 1.5 = 12.0 per week Preparer hours those need 12.0 x 6.0 = 72.0 per week Offshore seats that supports 72.0 / 35 = 2.1 seats
Now read it the other way, to see what a third seat costs Three seats produce 3 x 35 / 6.0 = 17.5 returns per week Review hours those would demand 17.5 x 1.5 = 26.3 hours per week Reviewer hours you actually have 18 = 8.3 hours short, every week
Notes on the inputs - Use your first-season review time, not your in-house time. The gap between the two is the ramp, and it closes over months, not weeks. - Usable preparer hours are lower than contracted hours. Training, query waits and leave all come out of the same block. - Every input here is yours. Nothing in this illustration is a benchmark, and a provider quoting one is quoting your job back at you. ```
Two things fall out of that arithmetic. The first is that the ceiling sits lower than it feels, and it is a ceiling on the arrangement rather than a target to hire toward, because until you have run a full cycle every input above is an estimate. The second is that the fastest way to raise the ceiling is not another preparer, it is anything that pulls your review time per file down: better workpapers, a written treatment list, or a second pair of eyes offshore before the file reaches you.
The Four Roles, and the Trigger for Adding Each
An offshore accounting team is usually four jobs, and a firm that hires them in the wrong order pays for it in reviewer hours. Fill each one when the constraint it answers is the one actually binding you.
The preparer. Builds the file: the reconciliations, the workpapers, the return, and a written list of open questions rather than assumptions. This seat decides which work types you can move at all, because anything that cannot be specified well enough for a preparer to follow is not offshore work yet. Add it first, and only for a work type you can describe in writing.
The independent checker. A maker-checker seat: the person who built the file is not the person who clears it. What decides this hire is the trigger, and it is specific. Your reviewer is sending files back for arithmetic, misclassification and missing support rather than for treatment questions. That is mechanical rework, it is the cheapest kind to catch offshore, and your reviewer's hour is the most expensive hour in the chain to spend on it.
The offshore senior. The first offshore hire you make for judgment rather than throughput. The trigger here is the content of your query list. When the questions coming back are about US treatment rather than about your firm's preferences, the team has outgrown a checker and needs a reviewer of its own. This is also the seat that decides whether the team can absorb a new client of a familiar type without a partner writing fresh instructions.
The team lead. Owns the queue, the schedule, the query list and the handovers. The trigger is your own calendar: when you spend more time allocating work and chasing status than reviewing output, the coordination job already exists and you are the one doing it. On a small team this is the offshore senior wearing a second hat, and it is worth saying which hours belong to which hat.
Pick a Shape: Embedded Seats or a Shared Pool
Two structures cover almost every firm, and they trade the same thing against each other: continuity against utilization.
Embedded puts each offshore person inside one of your client-serving groups. They learn that group's clients, that partner's preferences and that book's recurring oddities, so query volume falls fast and quality on those files climbs. The cost is shape. That group's quiet weeks are the seat's quiet weeks, and the person is idle exactly when your other groups are drowning.
Pooled runs the work into one queue that any preparer can pick up. Utilization smooths out, cover is easy when someone is on leave, and the team scales without renegotiating who belongs to whom. The cost is that nobody accumulates client knowledge, so your documented procedures have to carry what people would otherwise remember. A pool without written treatments produces consistent output at a consistently mediocre level.
The tell is where your firm's knowledge actually lives. If it lives in relationships and partner habits, embed, and accept the utilization hit. If it lives in written procedure, pool, and spend the saving on keeping the procedures current.
A firm can also end up pooled by accident, with one offshore person absorbing overflow from everyone, and that arrangement gets the worst of both: no client knowledge, no smoothing, and a queue whose priority changes with whoever asked last. Choosing the shape deliberately at two or three seats is cheaper than sorting it out at six.
The Two Seats the IRS Puts a Status Test On
Some of your team's structure is not a preference. The e-file rules attach requirements to named individuals, and those requirements decide who can hold two specific seats.
Who Can Be Named, and Who May File
Everyone your firm lists as a Principal or Responsible Official must "Be a United States citizen or an alien lawfully admitted for permanent residence as described in 8 USC 1101(a)(20)", must "Be at least 18 years of age as of the date of application", and must meet applicable state and local licensing and/or bonding requirements for the preparation and collection of tax returns (IRS Publication 3112, IRS e-file Application and Participation).
Read the scope before you redraw the org chart. The requirement binds two named roles, Principal and Responsible Official, not everyone who works on a return. And it is a status test rather than a location one, because it asks what someone is rather than where they sit.
The filing step is fenced separately. "Providers may use only other Authorized IRS e-file Providers to perform IRS e-file activities, including origination and transmission of electronic submission" (IRS Publication 3112). Beginning the electronic submission of a return under your firm's number is not preparation, and the rule limits who you can route it through: an outside firm performing that step has to be an Authorized IRS e-file Provider itself.
Who Signs, and What Counts as Judgment
Two more lines decide what stays home, and both sit in the tax rules rather than the e-file ones. Section 301.7701-15(b)(1) defines the signing tax return preparer as the individual tax return preparer who has the primary responsibility for the overall substantive accuracy of the preparation of the return. And section 301.7216-2(d)(1) draws its line at "substantive determinations", which it defines as work involving "an analysis, interpretation, or application of the law". That line is written for disclosure to another preparer inside the United States, so read it as the definition of judgment rather than as the rule that governs an offshore team. Design the team so the responsibility and the judgment those two describe never drift offshore by default.
If You Build Your Own Overseas Entity
Firms that go further and employ the team directly run into the citizenship test head on, and the IRS has a documented path for it. A Provider may obtain an EFIN for a firm in "its business-related group" when that firm cannot get one because its Principals and/or Responsible Officials are not United States citizens or aliens lawfully admitted for permanent residence, and the Provider "is responsible for the business-related firm's adherence to IRS e-file rules, but is not responsible for the preparation of returns of the firm in its 'business-related group'" (IRS Publication 3112).
The Internal Revenue Manual describes the same route from the other side. "Companies located outside the United States, who do not have employees with Social Security Numbers and are not eligible to register for e-Services, must meet specific requirements to obtain an EFIN", and a foreign EFIN is "a special privilege" the IRS can ask the Provider to inactivate where it believes the overseas firm is not following the e-file rules (Internal Revenue Manual 3.42.10.18).
Read that responsibility split before you decide. Your US firm carries the overseas entity's adherence to the e-file rules, which is a supervision obligation you are volunteering for on top of running a foreign employer.
The Updates That Follow a Team Change
The maintenance duty is the part that catches growing teams. "Providers must submit updates within 30 days of a change of any information", the same publication names Principals, Responsible Officials and "removing individuals no longer associated with the firm" among the updates it expects, and "When adding a new person, you must resubmit the application for processing" (IRS Publication 3112). Restructuring a firm around a new offshore arrangement is exactly when those names change, so put the update on the same checklist as the org chart.
Nor is the citizenship test a one-time gate. The Internal Revenue Manual has an IRS unit running a match twice a year, in "May and December", to identify any Principal or Responsible Official without a valid citizenship indicator for participation in the e-file program (Internal Revenue Manual 3.42.10.14.7.12.1).
Design the Working Week Before You Fill the Seats
An offshore team's calendar is a design decision, and it is easier to set now than to renegotiate in March.
Start with the query loop, because that is what the overlap window is for. Fix one block of hours when your reviewer and the offshore team are both working, and protect it. A team that can get an answer the same day finishes files; a team that waits until tomorrow stacks up half-built work and calls it capacity.
Then decide what the offshore day has to produce while your office is closed. The right output is a finished file plus a written query list, not a file stalled on the first question. That standard is worth writing into the procedures rather than hoping for, because it is the difference between a night of work and a night of waiting.
Blackout dates come next. Your team's public holidays are set by another country's calendar, and its leave entitlements are set by another country's employment rules, so neither will line up with your peak by accident. Ask for the leave plan in writing before the season, name the weeks nobody takes leave, and agree what cover looks like when someone does.
What "Built" Looks Like, and How You Know
A team is built when the work stops depending on you to move, and when your review hours per file have settled at a number you would sign up for again. Four signals say you are there, and none of them are a rate card.
The first is training that no longer routes through your office. When the second offshore person is brought up to speed by the first, on your procedures, without a partner running the sessions, the knowledge has moved from your head into the team.
The second is the shape of the query list. Early queries are about your firm, where a file lives, what you call a workpaper, which template to use. Later queries are about the client. When the questions are judgment questions you would also have asked, the specification has landed.
The third is a familiar new client absorbed without new instructions. If a new engagement of a type you already send starts cleanly on the existing procedures, the team owns the work type rather than the individual files.
The fourth is a rolloff that does not hurt. When somebody leaves and their replacement is productive inside the notice period, the work was held by the procedure rather than by the person, which is the difference between a team and a good individual. This is the signal you can buy in advance: agree the notice period at contract stage, and agree that the person leaving overlaps with the person arriving on live files. Continuity built into the contract survives a resignation; continuity assumed does not.
When Not to Build a Team
Building a team is the wrong move more often than the phrase suggests, and the honest signals are easy to check before you spend anything.
Your reviewer has no slack. If the review chain is already the bottleneck, more prepared files lengthen the queue rather than clearing it. That is a reviewer problem, and it has to be solved before a preparation seat helps.
The work is not written down. A team executes a specification. If your treatments live in one senior person's memory, the ramp will consume exactly the time you were trying to save, and the gaps will show up as inconsistency rather than obvious error.
The volume is small or one-off. A team is a fixed structure. Work that arrives once, or in quantities a single contractor could absorb, does not justify the coordination that a team costs.
Your clients will not consent. Consent for disclosure outside the United States is a real veto, and a book where a meaningful share of clients decline has decided the scope of any offshore model for you.
Nobody at your firm will own it. The compliance sequence, the procedures and the review standard all need a named owner. Unowned, they become the thing you discover was missing in the middle of your busiest week.
Questions Firms Ask
What Is an Offshore Accountant?
An accountant or tax preparer who works on your firm's files from another country, on your software and your procedures, under your review. The word describes where the person sits, not who employs them, and your own employee in an overseas office is offshore in the sense that matters to the disclosure rules.
How Do You Manage an Offshore Accounting Team?
Through the queue and the query list rather than through supervision. Agree what a finished file looks like, fix the overlap hours when questions get answered, and hold a short weekly review of rework and open queries with the offshore senior rather than with each preparer. The better the specification, the less management the team needs, which makes written procedures a management tool as much as a compliance one.
How Many People Should an Offshore Accounting Team Start With?
One. The ceiling is your review capacity, and until you have measured what offshore work costs your reviewer per file for a full cycle, every seat past the first is a guess. The second seat is a decision you make with data from the first, not before it.
Can Our Offshore Team File Returns for Us?
Preparation can move. The e-file activities themselves, including origination and transmission, may only be routed through an Authorized IRS e-file Provider, and the individuals named as Principal or Responsible Official on your application have to meet the citizenship, age and licensing tests the IRS sets.
Do We Need Our Own Entity Overseas?
Only if you want to employ the team directly and are prepared to run a foreign employer. Standing up an entity, payroll and statutory filings in another country is a commitment made before you know the model works, which is why placing people through a provider is the cheaper way to be wrong about a first team.
Start With One Seat and a Named Reviewer
Building an offshore accounting team looks like a hiring problem and behaves like a sequencing one. The compliance steps have to be finished before data moves, the review capacity has to be measured before seats are added, and the shape of the team has to be chosen while it is still small enough to change.
So start narrow. Name one work type, price your reviewer's time on it, settle the consents and the contract, put one preparer on real representative work, and add the next role only when a constraint you have measured says to. Built that way, the team is still small when you find out what you got wrong. Built to a headcount target, you find out in March, when the ceiling turns out to have been review all along.
If that sequence describes a decision you are about to make, don't trust us, test us. Accountably places trained offshore accountants and tax preparers inside US CPA and EA firms, ramped on your software and SOPs in about 3 to 4 weeks, and since 2022 that has meant 30+ placements across 20+ US firms. The low-risk way in is a Free 40-Hour Proof Pilot, a fixed block of your own representative work put through full multi-layer review so your reviewer grades real output first, and if a placement is not a fit in the first 30 days we replace them free.
