Client Portal Pilot

Branded intake links where clients upload W-2s, 1099s and K-1s from any device, no logins required.

Auto-Draft Intake & Workpapers

Client intake is auto-drafted, then every document is read, classified, and bookmarked into a clean workpaper, grouped by form type and issuer.

Firm Analytics

See every return's status and your firm's throughput at a glance. Nothing slips through the cracks.

E-Signatures Pilot

The 8879 goes out for e-sign; the signed form lands back in your workflow automatically.

1,100hrs

Our workpaper-prep automation is already saving clients 1,100 hours every busy season, the equivalent of 27 weeks of full-time labor returned to the firm.

Coming soon, beta spots are limited

The tax engine is coming. Built by people who've filed thousands of returns.

Built to feel familiar from the first login, so your preparers keep their muscle memory.

Documents flow in. Everything gets flagged automatically.

The moment a client uploads, their documents go straight into the filing system. Every field that needs your attention is flagged. You're not hunting for anything.

Open APIs, so you never have to worry about UltraTax closing down source data entry again.

Built open from day one. Any tool in your stack can connect. No more being held hostage to a vendor's decisions about what data you can access.

Up-front pricing, so you won't get a bill in year 4 at double what you paid in year 1.

Fixed pricing based on number of returns. No surprises, no "platform fees" that appear after you've migrated everything. What you pay today is what you pay.

The claim

Tax firms can file 1040s in 30 minutes. A human reviews every line.

We're not replacing CPAs. We're replacing the three hours of manual data entry between getting documents and reviewing a return. Every field is sourced from a document. Every position is explained. Every return is reviewed by a human before it's filed.

What happens when you use it

CPA firms across the US saved thousands of hours this tax season.

Twelve-person firm. Intake was all email. Missing documents found the week of deadline. They were about to hire two part-time admin workers.

One season on Luca IQ later, nothing in their tax setup changed. Admin prep down 57%. Senior staff doing tax work again. The part-time hires never happened.
