Frequently asked questions

How much time does AI save on tax returns?

Typically 50-60% — simple 1040s from 60 to 25-30 min, complex business returns from 20 to 10-12 hours. Time savings include AI extraction verification.

Can AI extract data accurately from K-1s?

Yes — modern AI extraction handles standard K-1s well. Verify amounts before relying on extraction, especially for complex K-1s with unusual reporting.

Does AI replace CPA review of returns?

No. AI accelerates prep and flags issues; CPA reviews and signs every return. Circular 230 due diligence requires CPA accountability.

Which tax software has the best AI for return prep?

Roughly comparable across UltraTax, Drake, ProSeries, Lacerte, CCH Axcess. Choice based on firm scale and ecosystem rather than AI features alone.

Should I bill clients hourly for AI-assisted returns?

Many firms shifting to fixed fees for standard returns. Hourly for complex returns with honest reflection of AI compression. ABA Formal Opinion 512 logic applies — honest billing for AI-augmented work.
