Tax Planning & Projection AI

Tax-planning strategy engines, projections and scenario tools, plus IRS transcript and resolution tools, with AI.

Eight tools, most of them with a posted price, that turn a client's 1040 into a plan the client can see the savings in. Holistiplan's OCR reads the return into a tax report for $749 a year on the Basic Tax tier; Tax Planner Pro, built by a CPA for solo CPAs and advisors, starts at $19 a month with Nova, its AI planning agent, on the $49 Max AI plan; TaxPlanIQ's jAIne flags strategies from bulk-uploaded returns at $397 a month; Instead's platform is free with AI agent credits from $30; and Intuit Tax Advisor comes at no additional cost with ProConnect Tax or Lacerte. CCH Axcess iQ predicts which clients a tax-law change affects and drafts the letter.

Two tools cover a narrower job well: TaxRock monitors clients' IRS accounts, decodes notices and lets Rocky, its AI assistant, explain what to do, priced per taxpayer for professionals; TaxTrex documents R&D credit claims for Swanson Reed review, free for accountants. Planning is seasonal, so each listing's note says what you get before year-end and what carries into the return.

Featured spot open. Put your tool at the top of this category for $149/month.
