Why this is the year for accounting firms let AI handle personal tax data-gathering: smoother, shorter, stress-free, and without hiring your way through every busy season.

Every January, the same problem resurfaces: your team spends weeks chasing clients for information that should have taken days to collect. Documents arrive incomplete, questions get answered out of order, and someone on your team has to read every reply to work out what’s still missing. The usual fix has been to throw more people at it; more seasonal staff, more overtime, more hours spent chasing rather than advising. In 2026, that’s no longer the only option.

The real cost of manual data-gathering

Chasing clients for personal tax information isn’t just slow; it’s expensive in ways that don’t show up as a single line item. Partners and seniors lose hours every week to email back-and-forth. Inconsistent chasing means some clients get missed until the deadline is uncomfortably close. And because the workload spikes so sharply in January, firms often end up hiring to cover a few weeks of pressure rather than a genuine, year-round need.

None of that is a resourcing failure. It’s what happens when a fundamentally manual process is asked to scale.

What AI changes

Glasscubes‘ Personal Tax AI Workflow takes the manual chasing out of the equation. Instead of your team tracking who’s replied, who hasn’t, and what’s still missing, the AI does it, directly with the client, at the point they’re already engaged.

Triage Questions ask every client the same five short, consistent questions during submission, ensuring they’ve properly considered what’s changed for them this year, so nothing depends on a staff member remembering to ask. Gap Analysis compares this year’s submission against last year’s to flag what’s missing or inconsistent, and can run quietly in the background or engage the client directly through the AI chat. Used together, on a request with an Aide-Mémoire attached, they deliver a complete submission- gathered, checked, and flagged before it ever reaches your desk. Firms using Glasscubes typically see a 40% increase in client response rates and save 2+ hours per request; time that used to go on chasing.

Coming soon: from gathered information to a working paper

The next step is already in early access: Personal Tax Working Papers. Once a request is complete, this turns the client’s documents and responses into a structured working paper; each figure is linked back to its source document, with a confidence score and reasoning, ready for your team to mark verified or correct with a click. You can add extra forms manually where needed, and the finished working paper downloads as a PDF.

This is the part that answers the “hiring” problem directly. Instead of a team member manually transcribing figures from PDFs and spreadsheets into a working paper, the AI does the first pass; your team’s job shifts from data entry to review and sign-off, exactly the higher-value work advisers are trained for. 

Change fatigue is real – but so is the pace of AI

Accounting firms haven’t had a quiet few years. Making Tax Digital, shifting reporting requirements, and a steady stream of new software have left plenty of teams feeling like they’re always adjusting to something. Adding “one more AI tool” can understandably land as fatigue rather than opportunity.

But AI itself isn’t standing still, and the case for using it is only getting stronger. That’s what makes this a leadership decision, not just a technology one: trusting that AI is advancing quickly enough to be worth adopting now, and setting that expectation for the team rather than leaving adoption to chance. Firms that treat it as optional, or leave it to a handful of early adopters to dabble with, will find themselves catching up later. Firms whose leadership pushes their teams to embrace it now will be the ones setting the pace.

What this means for your busy season

Put together, the shift is simple: less of your team’s time goes into gathering and re-keying information, and more of it goes into reviewing and advising. That’s a shorter, smoother season for your staff, a faster, less repetitive experience for your clients, and a busy season that scales without a proportional scramble to hire.
