The problem

Tax prep is 70% data entry.

Every CPA knows the breakdown. The actual tax expertise — the planning, the deduction analysis, the client advisory — is maybe 30% of the hours on an average return. The other 70%? Pulling numbers from W-2s, transcribing 1099s, categorizing business expenses, double-checking prior-year comparisons.

The work is important. It has to be accurate. And it's being done by people you're paying $50–120/hour to do data entry.

An AI agent can extract, categorize, and validate source documents — and your CPAs spend their billable hours doing CPA work.

The playbook

The six-step tax prep workflow, step by step.

Each step shows what the agent does autonomously and what your team sees on their end. Human approval gates are marked.

01

Agent parses and categorizes everything

Client uploads documents
Agent does

W-2s, 1099s, K-1s, brokerage statements, receipts, bank statements — extracted line-by-line with document provenance.

Your team sees

Extraction shows in the prep workspace with confidence scores.

02

Agent flags anomalies and mismatches

Approval gate Validation pass
Agent does

Compares current-year data to prior-year. Flags missing forms, unusual variances, and potential deduction categories.

Your team sees

Flags appear in the CPA review queue with context and suggested follow-ups.

03

Agent surfaces candidates the CPA should consider

Deduction and credit scan
Agent does

Scans expenses for business deduction categories. Cross-references life events and income changes with credit eligibility.

Your team sees

Ranked list of deduction opportunities for CPA judgment.

04

Your CPA makes the calls

Approval gate CPA review session
Agent does

Reviews flagged items, validates deductions, makes judgment calls on grey areas. Agent updates the return in real-time as decisions are made.

Your team sees

What used to take 3–4 hours now takes 45 minutes of focused review.

05

Agent drafts targeted client follow-ups

Client Q&A on open items
Agent does

For any missing info, the agent drafts a specific question email. CPA reviews and sends.

Your team sees

Clients get one clean email, not five back-and-forths.

06

Agent packages the return for CPA signoff

Approval gate Final assembly and filing prep
Agent does

All schedules assembled, supporting docs linked, review memo drafted.

Your team sees

CPA does final review and e-files. Audit trail logged.
