To automate tax season, split each return into its stages and hand software only the repetitive ones: collecting client files, sorting them, checking them against last year and chasing what is missing. Keep judgment work, such as reviewing positions and signing, with a preparer. Start with document intake, because every later stage waits on it.
Which tax season stages can software automate today?
Software can take over most of the clerical stages of a tax season return: receiving client files, sorting pages by document type, comparing the folder with last year's, flagging what is missing, drafting reminders and moving figures into a spreadsheet. It can help with data entry and status tracking. It cannot decide how anything is reported on a return.
The useful way to think about automation is stage by stage, not product by product. A return in a firm passes through roughly eight stages between the engagement letter and the e-file acknowledgment. The post on the stages of a tax season workflow maps each one with its owner and its entry and exit conditions, so this section only scores them.
The table below is an example scoring for a small firm doing mostly individual returns. Your own scores will differ with your client mix and your current tools.
| Stage of the return | Can automate | Partly | Keep manual | First step to take |
|---|---|---|---|---|
| Engagement and organizer | Sending the same letter and organizer to every returning client | Tracking who has signed | Scoping a new or changed engagement | List returning clients and their prior-year forms |
| Document intake | Receiving files from one link per client, sorting pages by type | Give each client a single upload point | ||
| Completeness check | Comparing received forms with last year's, flagging duplicates | Asking about new income sources | Deciding when a file is complete enough to start | Build expected-items lists from last year's returns |
| Client follow-up | Drafting a list of what each client still owes | Choosing the tone for a slow client | Calling a client who has gone quiet | Set a weekly day for reminder drafts |
| Data entry | Moving figures from forms into a spreadsheet or import file | Checking those figures against the source page | Entering items that need interpretation | Pick the three forms you key in most often |
| Preparation | Prior-year carryovers and rollover of client data | Every reporting decision | Leave as it is | |
| Review | Sorting returns into a queue | The review itself and the notes it produces | Write down how the queue is ordered | |
| Signature and e-file | Status tracking and acknowledgment logging | Confirming every wage and distribution form is in hand | Keep a gate before transmission |
Read the table from left to right as a funnel. The first four rows are where software does the most, because the work is the same for every client: a W-2 is a W-2 whichever employer issued it. The last three rows are where software only supports a person, because each return raises its own questions.
Data entry sits in the middle. Reading a printed figure off a form is mechanical, but checking that the right figure went to the right line is not. The manual data entry cost formula shows how to put a number on that work for your own firm before deciding how much of it to hand over.
Tax season tasks that still need a preparer
Tax season tasks that need a preparer are the ones where the answer depends on facts and judgment rather than on reading a page: deciding how an item is reported, reviewing a return, answering a client's question, deciding a return is ready to file and signing it. Software can prepare the ground; it should not make the call.
Reporting decisions
Every return has a few items that do not fit a template. A client sold a rental, started a side business mid-year, or received a K-1 with codes the firm has not seen before. Software can surface the document and its figures. Choosing how they land on the return is the preparer's work, and no tool that only reads documents should be described as doing it.
Review and supervision
Review stays with people for a regulatory reason as well as a practical one. Treasury Circular 230 (Rev. 6-2014), section 10.22, says a practitioner is presumed to have exercised due diligence when relying on another person's work product only if the practitioner used reasonable care in engaging, supervising, training and evaluating that person. Section 10.36 asks those with principal authority over a firm's practice to take reasonable steps to make sure the firm has adequate procedures. Automated output is still work someone has to supervise. The IRS Circular 230 page for tax professionals describes who these rules apply to.
The gate before e-file
Transmission has a hard rule that automation should not skip: the IRS page on e-file providers and Forms W-2, W-2G and 1099-R bars authorized e-file providers from submitting a return before they receive all of those forms. A completeness check can tell a preparer which forms are in, but a person should confirm the gate, which the post on the stages of a tax season workflow writes into the e-file entry condition.
Client conversations
A client who has not answered three reminders is not a data problem. A short call usually gets further than a fourth message, and deciding when to make it is a judgment about that client.
Where should a firm start automating tax season first?
A firm should start automating tax season at document intake, the stage where client files arrive. Intake runs before every other stage, it is the same for every client, and its failures spread: a missing 1099 found during review sends the return back to the start. Fixing intake first shortens the wait at every stage after it.
Intake also hides time that nobody records. Files arrive by email, text message, portal download and paper drop-off. Someone has to open each one, work out what it is, rename it, file it in the right client folder and tick it off a list. None of that is preparation, and all of it has to happen before preparation can start.
The second place to start is the completeness check. Once documents arrive in one place, comparing them with last year's set is mechanical. If a client had a 1099-DIV from a brokerage last year and none has arrived this year, that is a line to chase. Doing it by hand means reading last year's return next to this year's folder. Doing it in software means the list is ready when the folder is.
Data entry can look like the obvious first thing to automate, but on its own it is the wrong first move. Extracting figures from a folder that is incomplete, unsorted and full of duplicates just moves the mess faster. The five ways to reduce data entry in accounting work post covers the options once intake is under control.
Schema CPA covers these first two stages: each client sends everything to one upload link, every page is classified by type, issuer and period, and the folder is checked against last year's return so missing and duplicate documents are flagged before anyone opens the return. The workflow section of the homepage walks through those steps, and the client document collection category covers intake methods in more depth.
A tax season automation rollout in three steps
A tax season automation rollout works best in three steps: test the new tool on a handful of real clients during the quiet months, extend it to all returning clients before the organizers go out, and only then connect later stages. Each step has an exit condition, so staff never run two half-finished systems at once.
Step 1: a small trial in the off-season
Choose five to ten returning clients with different document mixes: a wage earner, a household with a brokerage account, a client with rental property and a small business owner. Run last season's documents for those clients through the new tool and compare its output with what the firm already knows was in each folder. The trial ends when the team can say, for each client, what the tool caught and what it missed.
Step 2: all returning clients, before engagement letters go out
Load every returning client's expected-items list before the first reminder of the season. This is the step that changes the workload, so do it while there is still slack. The exit condition is that every returning client has one intake point and one list.
Step 3: connect the next stage
Only after intake is stable, decide whether to connect the next stage, such as moving extracted figures into the spreadsheet or import file your preparers use. One connection at a time keeps problems traceable. If something breaks in February, the team knows which change caused it.
What to tell staff
Seasonal staff need one page, not a training course. Say where client files now arrive, who owns each client's list, and what to do with a document the tool could not classify. Keep the old process documented for the first season in case a client insists on it.
Tracking which returns sit in which stage is a separate job from reading their documents. The guide to what tax workflow software should track covers that side, including how to trial a tracking tool with real returns.
Automating tax season mid-February: when not to switch
Switching tools in the middle of tax season is usually a mistake once most clients have started sending documents. By mid-February, staff are working from habit, client folders are half full in the old system, and a migration splits each client's file across two places. Wait unless the current process is failing outright.
Signs it is too late this season
A few conditions make a mid-season switch more expensive than the problem it solves:
- More than half of returning clients have already sent their first batch of documents to the old location.
- The only person who could learn the new tool is also the firm's main reviewer.
- The tool needs every client to change how they send files, and reminders are already out with the old instructions.
- Business returns are close to their own due date. IRS Publication 509 (2026), the tax calendar for calendar year 2026, says Forms 1065 and 1120-S are due on the 15th day of the 3rd month after the end of the tax year, and that a due date falling on a Saturday, Sunday or legal holiday moves to the next business day. For calendar-year tax year 2025 returns, that puts the deadline in mid-March 2026.
When a mid-season change is still worth it
Some changes are small enough to make at any time. A firm can start using a single upload link for new clients only, leaving returning clients where they are. It can start a duplicate check on folders that are already in. It can also use the rest of the season to collect examples of what went wrong, which makes the off-season trial in step one much sharper.
A worked example of the decision
This example is fictional. Larkspur Tax Group, a three-person firm, has 140 returning individual clients. On February 14, 2026, during the season for tax year 2025 returns, 85 of them have sent at least one batch to the firm's shared inbox. The firm is considering a new intake tool.
Moving 85 partly collected folders means re-sorting every file already received and resending instructions to 85 clients mid-season. Leaving them alone and pointing only the 55 clients who have not started at the new tool splits the firm into two systems for two months. Larkspur decides to wait, writes down every document it chased late this season, and runs the trial with ten of those clients in June.
When the firm is ready for that trial, the Free plan covers up to three clients, and Get started sends a sign-in link by email.
