Assigning clients to preparers works best as a January worksheet: score each client's return for complexity, estimate its hours, match it to a preparer whose experience fits, and keep last year's preparer when the fit still holds. Then total the hours per preparer, not the client count, and move clients until no one is overloaded.
Criteria for assigning clients to preparers
The criteria for assigning clients to preparers are return complexity, preparer experience, the client's history with the firm, and each preparer's total workload. Complexity and experience decide who can do a return well. History decides who already knows the client. Workload decides whether that person has room. A good assignment satisfies all four.
Complexity is the starting point because it limits who can take a return. A simple score works: 1 for a wage-and-interest return, 2 for itemized deductions or a small Schedule C, 3 for rentals or several K-1s, 4 for multi-state or foreign items, 5 for anything the firm sees only a few times a year. The score is a planning number, not a measure of the client. It answers one question: who on staff can prepare this without heavy review?
Experience is the matching half. Give each preparer a ceiling, the highest complexity score they handle on their own. A second-season preparer might have a ceiling of 3. A senior might have 5. A return above someone's ceiling can still go to them as a training assignment, but it should be marked that way and given extra review time.
History covers what the firm already knows. Which preparer did this client last year? Were there notes about missing documents, a difficult contact, or an unusual item? A client whose prior preparer has left the firm is a new client in every practical sense, and the worksheet should say so.
Workload comes last because it depends on the other three. Once each client has a suitable preparer, add up the hours. That total, compared with each person's available hours, shows where the plan breaks.
Edge cases: linked returns and shared households
Some clients bring more than one return. A household whose members own an S corporation, a family partnership and a rental LLC produces several returns that share facts. Assign the linked returns to the same preparer, or at least the same reviewer, so a figure that flows from one return to another is checked once by someone who sees both sides.
Households that split are the opposite case. Spouses who filed jointly last year and separately this year, or an adult child who now files alone, become two clients. Give each its own row on the worksheet, with its own complexity score and hours, and note who prepared the combined return last year. That person is still the best source of history, even if only one of the new returns stays with them.
Clients who arrive mid-season, through referrals or from another firm, need a row too. Leave a small reserve of unassigned hours on the worksheet for them, rather than squeezing them into whoever looks least busy in March.
A complexity score is easier to set when the firm knows what documents a return usually involves. The tax document checklists category lists the forms that typically come with each return type, which makes a client's score less of a guess.
Should the same preparer keep a client every year?
Keeping the same preparer for a client every year saves time and catches more, because that preparer remembers last year's documents, quirks and open questions. The risk is concentration: the client's knowledge lives in one head, the preparer may stop questioning old assumptions, and the firm is exposed when that person leaves or falls behind.
The gains are real. A returning preparer knows the client usually sends a brokerage statement in two parts, or that the rental property was sold in the fall. They spot a missing form faster because they remember it from last year. The client also tends to answer questions faster from a familiar name.
The risks build slowly. A preparer who has done the same return for six years may copy last year's treatment forward without checking whether anything changed. A partner reviewing that return may give it less attention for the same reason. And if every complex client sits with one senior, the firm's busiest weeks depend on that person staying healthy.
A balanced rule keeps continuity as the default and adds two checks:
- Rotate the reviewer, not the preparer. A fresh reviewer every few years brings new eyes without losing the preparer's memory of the client.
- Write history down. Notes on prior-year items, expected documents and client habits belong in the client file, not only in someone's memory. Then a reassignment costs hours instead of weeks.
Continuity questions are worth revisiting after each season. The tax season post-mortem is where a firm can ask which long-held assignments ran smoothly and which hid problems.
Balancing preparer assignments by hours, not client count
Balancing preparer assignments by hours means comparing the estimated hours of each preparer's clients with that person's available hours, instead of giving everyone the same number of clients. Forty simple returns and forty complex returns are very different seasons. Counting clients hides that difference. Counting hours shows it before the first document arrives.
Each client gets an hours estimate on the worksheet. The estimate can come from last year's time records for that client, or from a typical figure for its complexity score if the client is new. How to build those per-return estimates, and how to compare them with staff hours week by week, has its own section in the post on estimating hours per return for capacity planning.
Available hours need the same care. A preparer who also handles bookkeeping clients, supervises a junior, or works part time in March has fewer season hours than the calendar suggests. Write each person's available hours on the worksheet next to their assigned total.
Example: an assignment worksheet
Everything in this worksheet is a fictional example. The firm, the preparers, the clients, the scores and the hours are invented to show the arithmetic.
| Client (example) | Complexity score | Est. hours (example) | Preparer | Prior-year preparer |
|---|---|---|---|---|
| Alder household | 2 | 3 | Priya | Priya |
| Brookfield household | 4 | 9 | Marcus | Marcus |
| Cedar Row LLC owners | 3 | 6 | Priya | Dana (left firm) |
| Dunmore household | 1 | 2 | Jo | none (new client) |
| Elm Street rentals | 3 | 7 | Marcus | Marcus |
| Fairview household | 5 | 12 | Marcus | Marcus |
The worksheet then totals each preparer's assigned hours against their available hours:
| Preparer | Complexity ceiling | Assigned hours (example) | Available hours (example) | Load |
|---|---|---|---|---|
| Marcus | 5 | 28 | 24 | 117% |
| Priya | 3 | 9 | 20 | 45% |
| Jo | 2 | 2 | 16 | 13% |
On client count, Marcus has three clients and Priya two, which looks fair. On hours, Marcus is over his available time and Jo is barely used. The fix in this example is to move the Elm Street rentals return (score 3, within Priya's ceiling) to Priya, bringing Marcus to 21 hours and Priya to 16. In a real worksheet the rows run to hundreds, but the move is the same: shift the returns that fit someone else's ceiling.
Reassigning clients to preparers mid-season
Reassigning clients to preparers mid-season means moving open returns from an overloaded or absent preparer to someone with capacity. It is worth doing when a preparer's queue is clearly longer than their remaining hours, or when someone leaves or falls ill. The cost is lost context, so the move needs a handoff note.
The signal to reassign usually shows up in the weekly status numbers before anyone complains. One preparer has many returns waiting for preparation while another has none. The work in progress report for tax firms lays out the counts by stage and preparer that make that imbalance visible each week.
Move returns that have not been started, if possible. A return with no work on it loses nothing when it moves. A half-prepared return loses the preparer's thinking, and the new preparer often redoes part of it.
A handoff note should cover:
- What is in. Which documents have arrived and which are still missing.
- What was done. Any work already entered, and where it stopped.
- Open questions. Anything asked of the client and not yet answered.
- Client contact. Who to call, and whether the client has been told about the change.
Tell the client. A short message that names the new preparer and says their documents and history moved with the file prevents the client from sending the next upload to the wrong person.
Keeping the document picture in one place makes the first item on that list easy. Schema CPA keeps each client's received and missing documents in one file, checked against last year, so the new preparer can see what is in and what is still owed. Review queues by preparer are part of the Practice plan. The pricing section lists what each plan includes.
What do new preparers get assigned first?
New preparers should be assigned first the returns with low complexity scores, a complete prior-year file, and a client who sends documents on time. Those returns teach the firm's process without stacking difficult technical work on top of it. A first-season preparer learns intake, workpapers and review notes before handling rentals or multiple K-1s.
The best first returns are ones a reviewer can check quickly. Wage-and-interest returns for returning clients, with last year's return in the file, give the new preparer a model to compare against. The reviewer can spend their time on habits and process rather than on technical corrections.
Raise the ceiling in steps. After a batch of score-1 returns go through review cleanly, add score-2 returns. Mark any return above the preparer's ceiling as a training assignment, with a named senior to ask and extra review time in the plan.
Avoid giving new preparers the leftovers. The clients nobody wants are often the ones with late documents, unclear history or difficult contacts. Those are hard returns for reasons unrelated to tax, and they teach a new person bad lessons about how the firm works.
Pair the first assignments with the same reviewer for the whole season. One reviewer sees the pattern in a new preparer's mistakes and can address it once, where three reviewers would each correct it separately.
