For accounting firms
AI for Accountants: Tax Season, Client Chasing and Notices
AI tools for accountants are most useful on the client-facing work around the numbers. That means chasing missing documents at tax season, drafting engagement letters, turning an IRS notice into a plain-English reply, and writing variance notes from a trial balance. You still sign off. Review, judgment and the return itself stay with your firm.

What it does
What can AI do for an accounting firm?
It can take most of the writing and chasing that surrounds each engagement. Karbon's 2026 report says 92% of accounting professionals already use AI in some form (Karbon, updated February 2026). For most small firms, the hours go to the jobs below.
Document chasing
- You ask
- “Who's still missing 1099s or K-1s from the list?”
- You get back
- A per-client list of what's outstanding, plus a polite reminder for each, ready to send
Engagement letters
- You ask
- “Renew last year's letters with the new fee schedule”
- You get back
- One letter per client, fees and scope filled in, flagged where scope changed
Tax-season status
- You ask
- “Send everyone a status update by Friday”
- You get back
- Short, client-specific emails: received, in review, waiting on you
IRS and state notices
- You ask
- “Client forwarded this notice, what does it say?”
- You get back
- A summary of what the notice claims, the deadline, the documents to pull and a draft reply for your review
Workpaper notes
- You ask
- “Explain the big swings in this trial balance vs last year”
- You get back
- Variance commentary by account, with the questions to ask the client
The firm-side version is different from an owner keeping their own books. That case is covered on owner-side bookkeeping.
Day one
What does that look like in a real week?
Three requests in a row on a Monday in March:
- Pull everyone on the 1040 list who hasn't uploaded a W-2 yet.
- Now write each of them a two-line reminder. Mention their preparer by name.
- And give me a one-page board of who's blocked on what, for Thursday's staff meeting.
You get back 23 drafts to approve and a one-page status board. Nothing goes out until you approve it. Next week you ask for the same thing in one sentence, because it remembers the list and how you phrase things. New clients go through the same flow at intake. See client onboarding for the engagement-to-first-upload sequence.
What should an accountant not hand to AI?
Hand off the drafting. Keep the judgment.
- The return and the opinion. Preparing, reviewing and signing stay with your licensed staff and your tax software (UltraTax, Drake, CCH, whatever you run). AI drafts the letter about the return. It does not prepare the return.
- Tax positions. Use AI summaries of a code section or notice as a starting point. Before advice goes to a client, a preparer checks it against the source.
- Client data without a plan. The IRS says Federal Trade Commission rules require professional tax preparers to "create and enact security plans to protect client data" (IRS). Write the AI tool you use into that plan. Upload only what the task needs.
- Bulk sends without a look. Keep every client email in review until the wording has proven itself.
How does Bento fit with QuickBooks, Xero and your tax software?
Bento sits beside the tools you already run. It doesn't replace them. It reads the exports you already pull from QuickBooks or Xero, the client list in a spreadsheet, and the documents clients send by email. From those it writes the reminders, letters, summaries and status boards above.
It works in Gmail, Slack, Notion and thousands of other apps. You choose, workflow by workflow, whether it drafts for your review or sends on its own.
It's one subscription for every kind of AI. The writing, the spreadsheet analysis, a client-friendly chart for an advisory meeting, even a short explainer video for your website. Each workspace is its own private cloud computer, so your client files stay together in one place.
Plans start at $20 a month, your whole team is included at no extra cost per person, and there's a 7-day free trial. See every plan.
It is not tax software, a practice-management system or a client portal. Keep those.
FAQ
Questions accountants ask first.
Is it safe to put client tax documents into AI?
It depends on the tool and your security plan. Use a tool where your files sit in your own private workspace, upload only what each task needs, and record the tool in the written security plan the FTC Safeguards Rule requires.
Can AI prepare a tax return?
Not in a way you should sign. AI is good at the work around the return: what's missing, what changed and what to tell the client. The return stays in your tax software under a preparer's review.
Can it read my QuickBooks or Xero data?
Yes, through exports you share or a connection with scoped permissions. Start read-only and in review mode, and widen it only once the output has held up through a month-end.
Will it help during busy season or only after?
Busy season is where it pays off most, because chasing and status emails grow with every client. Set it up in January on last year's client list, before the volume arrives.
It’s all in the box already.
