AdvisorCal vs Holistiplan: tax planning tools compared

What Holistiplan actually does

Holistiplan's core product is a tax-return reader. You upload a client's PDF 1040, the software OCRs it, extracts every line, and produces a one-page tax planning report highlighting opportunities like Roth conversion room to the top of a bracket, IRMAA cliffs, charitable bunching, or capital gains harvesting space. It's used during client review meetings to make tax planning visual and concrete.

What AdvisorCal does in the same space

AdvisorCal includes forward-looking tax calculators that an anonymous prospect can use without uploading anything. The user types in projected income, filing status, deductions, and the calculator returns marginal and effective rates, IRMAA tier projections, Roth conversion break-evens, and so on. The output is for the user to see — and (with permission) for you to receive as a lead.

The order to add them

Most growth-stage advisors should add AdvisorCal first because it's cheap and works on prospects without any client relationship. Once you have enough clients with tax returns to analyze, add Holistiplan to deepen the planning conversation in reviews.

Where Holistiplan beats anything else

Reading an actual 1040 is genuinely hard, and Holistiplan does it well. If your practice is tax-focused and you're already doing tax planning meetings with retainer clients, nothing else surfaces opportunities from a real return as fast.

The new Nitrogen Tax Center wrinkle

As of late 2025, Nitrogen launched a Tax Center at $99/month (annual term, ~$1,188/year) that also ingests 1040 PDFs and runs tax planning. It's now Holistiplan's most direct head-to-head competitor on price and feature scope. Advisors already paying for Nitrogen Risk or Research Center may find the Tax Center add-on cheaper than a standalone Holistiplan subscription. Holistiplan still has the depth-of-feature advantage from having focused on this single problem since 2019.

Bottom line

These tools are not in competition — they're stacked. AdvisorCal at the top of funnel ($19.99/month, anonymous prospects on the website). Holistiplan in the back office (~$1,800/year, existing clients with real tax documents). Together they let a tax-focused advisor go from "stranger on Google" to "client with a written tax plan" without gaps.
