Most of the returns on your desk in March aren't really unfinished. They're ninety percent done, waiting on three things: a 1099 that never came, a K-1 from a partnership that files late, a signed e-file authorization the client keeps meaning to scan. The tax work is finished. The paperwork isn't.
So the file goes into a pile you've all started calling 'waiting on client,' and it sits there. You know roughly what's missing, but roughly isn't enough to file. Someone has to open the folder, remember what was outstanding, and send yet another email that the client reads at a stoplight and forgets by the next one.
By early April, that pile is the whole job. Your staff spends their days not preparing returns but re-reading half-finished ones to work out what's still missing, then writing one-off nags. That's the part worth fixing. Not the tax work, the chasing.
Why three missing documents cost a whole afternoon
A return stalled on one document isn't one problem. It's a problem you have to reconstruct every time you touch it. Open the file, read your own note from two weeks ago, check whether the K-1 showed up, confirm the client never sent the mortgage interest statement, then write the email. Do that across forty open returns and you've spent the afternoon remembering, not preparing.
The second cost is vaguer and worse. When you send a generic 'we still need a few things to finish your return,' the client has to do the remembering for you. Which things? They don't know. So they do nothing, or they resend what they've already sent, and the loop repeats.
What you want is a single place that always knows the exact state of every return: what's in, what's still out, who was asked last, and when. Build that once and the afternoon of re-reading mostly goes away.
Build a per-client checklist that tracks what's actually outstanding
Start with the list of documents each return needs, by client, not a generic template. A retired couple with a brokerage account, a rental, and Social Security has a different list than a dentist with a pass-through and a SEP. Last year's return is your best starting point: whatever showed up then probably shows up again.
For each client, the checklist should carry one row per expected document, with a few fields:
- What it is, named the way the client would recognize it ('1099 from Fidelity,' not 'brokerage income statement').
- Status: received, outstanding, or not applicable this year.
- Who's responsible, you or the client, since some documents you pull yourself.
- Date last requested, so nobody asks twice in three days or forgets for three weeks.
- A secure upload link tied to that client, so the reply has somewhere to land that isn't a crowded inbox.
The format matters less than the discipline. A shared spreadsheet works. Your tax software's client portal may already do most of it. The point is that anyone on staff can open one view and see, without re-reading the file, that the Santos return is waiting on exactly one K-1 and a signature.
Make the ask specific, every time
The difference between 'we need a few more documents' and 'we still need your mortgage interest statement, Form 1098 from your lender' is the difference between an email that gets ignored and one that gets acted on. Specific asks tell the client exactly what to find and where to look.
Name the document the way it arrives in their life. People don't think '1098.' They think 'the thing from the mortgage company.' So write both, and if you know the lender, name the lender.
- Instead of 'outstanding items,' write 'one document: your 1099-INT from Rockland Trust.'
- Instead of 'please upload your paperwork,' write 'upload your 1099-SA here, the HSA form showing what you withdrew for medical costs.'
- Instead of 'we need your signature,' write 'sign Form 8879, the one-page e-file authorization that lets us submit, link below.'
One request per missing item, each with the upload link right there, beats a wall of text listing everything. If three things are out, that can still be one message with three clearly separated asks. Clarity is the whole game.
Stage the reminders so they escalate on their own
Once the checklist knows what's outstanding and when you last asked, the reminders can send themselves on a schedule you set, and this is where a bit of automation earns its keep. You're not writing forty emails. You're writing three templates and letting the system drop in the specific missing item and the client's name.
- First nudge, friendly, about a week out: 'We're almost done with your return. We're waiting on one thing, [item]. Upload it here.'
- Second, a few days later, a little firmer: restate the item, note the deadline, offer to answer any questions.
- Third, as the date nears: make the consequence plain. 'To file by the 15th we need [item] by [date]. After that we'll file an extension.'
Each reminder pulls the specific outstanding item from the checklist, so the client never gets a vague 'still waiting' when you actually know it's the one 1099. When the document lands, you mark it received and the reminders for it stop. Nothing annoys a client faster than a nag for something they sent on Tuesday.
Figure this gives you back a real chunk of the season. If chasing documents eats an hour a day across your staff through March and early April, trimming most of that is weeks of hours you get to put back toward billable work.
Where the assistant helps, and where you still have to look
Be honest about the boundary here, because it's easy to oversell. Software is good at the mechanical parts: tracking status, remembering who was asked when, sending the specific reminder, giving the client a safe place to upload. That's most of the volume and nearly all of the tedium.
What software is not good at is deciding what's actually missing. That's judgment. A client sends a brokerage statement and the system marks the 1099 received, but you still have to notice it's missing the cost basis, or that there's a new account that wasn't there last year, or that the K-1 reports something that changes the rest of the return.
The same goes for the document that shouldn't be there at all, or the one figure that looks wrong. An assistant can tell you a form arrived. A human has to read it and decide whether it's right and complete. Let the tool run the chase, and keep the review where it belongs, with the preparer.
Worth setting up this week
You don't have to automate anything to start. The checklist is the part that pays off first, and you can build it by hand.
- Pick your ten most reliably-late clients and build a per-client checklist from last year's return. That's where the chasing concentrates.
- Rewrite your standard 'we need documents' email into specific, named asks, one item per line, each with an upload link.
- Draft the three staged reminder templates, friendly, firmer, deadline. Keep them short.
- Decide, in writing, what a human checks before a return is called complete, so nothing quietly files with a hole in it.
- If the manual version holds up this spring, that's when it's worth wiring it into your portal so the reminders send themselves.
If you'd rather not assemble it piece by piece, setting up exactly this kind of tracking for Massachusetts practices is what we do. Either way the win is the same: your staff stops re-reading half-finished returns, and the files start closing on their own.
