The short version

  • Only TaxAct has a free tier, so it costs nothing to try first.
  • Each has a real cost: Causal causal was acquired by Lucanet on 31 October 2024 and the independent brand has been retired in favour of Lucanet xP&A, so the roadmap, support and pricing you buy are Lucanet’s and not the ones the product built its reputation on.; TaxAct free edition available only to approximately 40% of filers
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Causal

  • Causal was acquired by Lucanet on 31 October 2024 and the independent brand has been retired in favour of Lucanet xP&A, so the roadmap, support and pricing you buy are Lucanet’s and not the ones the product built its reputation on.
  • Self-serve pricing is gone: the old causal.app pricing page now redirects to a Lucanet solution page, so what was a transparent product you could sign up for is an enterprise sales conversation with no published rate.
  • The variable-based model is a genuine departure from spreadsheet thinking, so an accountant fluent in Excel must relearn how to express a model, and the team members who could previously all edit the forecast often cannot at first.
  • Deep Excel compatibility is limited by design; complex existing workbooks with macros, circular references or heavy lookups do not import cleanly and have to be rebuilt, which turns a tool evaluation into a modelling project.
  • Consolidation, statutory reporting and multi-entity currency handling are weaker than in dedicated corporate performance management suites, so a group with several legal entities usually needs Lucanet’s other modules alongside it, raising the real cost well past the planning tool alone.

TaxAct

  • Free edition available only to approximately 40% of filers
  • Pricing excludes separate state filing fees
  • Xpert Full Service pricing available on request only

Answered from the vendors’ own pages

The product does, as Lucanet xP&A. The independent Causal brand and self-serve offering have been retired following the October 2024 acquisition.

TaxAct offers a free edition for approximately 40% of filers, Deluxe at $59.99, Premier at $99.99, and Self-Employed at $109.99 per tax year.

Causal: What does it cost now?

Nothing is published. The former pricing page redirects to Lucanet, and the product is quoted as part of the Lucanet CFO Solution Platform.

TaxAct: Is TaxAct truly free for eligible filers?

Yes, TaxAct's Free Edition is available at no cost for W-2 employees, students, and filers meeting basic income and deduction requirements.

Source
Causal: Can I import my existing Excel model?

Simple workbooks import. Models with macros, circular references or heavy lookup chains have to be rebuilt around named variables, which is the real migration cost.

TaxAct: What is the difference between Premier and Deluxe plans?

Premier adds support for investment income, capital gains, cryptocurrency, rental properties, and home sale reporting compared to Deluxe.

Source
Causal: Is it a replacement for a consolidation tool?

No. It plans and forecasts. Statutory consolidation and multi-entity reporting sit in Lucanet’s other modules.
