Quick answer

The best tax planning software depends on how your firm works. Corvee and TaxPlanIQ are built for firms that sell tax planning as an advisory service. Holistiplan is popular with financial advisors who review 1040s. Intuit Tax Advisor, Planner CS, CCH ProSystem fx Planning and Drake Tax Planner work alongside their makers' tax prep software. Bloomberg Tax Income Tax Planner handles deep multiyear individual projections.

Key takeaways
  • Start with the tax software you already use. Built-in planners are often the cheapest, fastest place to start.
  • If you sell planning as its own service, look at Corvee and TaxPlanIQ for strategy libraries and client-ready deliverables.
  • Only TaxPlanIQ and Holistiplan publish prices. For the rest, get a written quote.
  • Software won't sell the plan for you. Your offer, your clients and your follow-through matter more.

Planners built into your tax software

If you already prep returns in one of these, start here. The data is already in the system, so there's less typing and less to go wrong.

IIntuit Tax Advisor

Works inside ProConnect Tax and Lacerte. Generates strategies from your returns, offers a strategy library or your own, and builds client reports that quantify savings. Since January 1, 2025 it requires a license per user.

TPlanner CS

Thomson Reuters planning software, updated through the year. Multi-year planning with carry-forwards, resident and nonresident state projections, comparative reports, letters and a Result Finder for what-if testing.

CCCH ProSystem fx Planning

Wolters Kluwer's 1040 planning tool with a spreadsheet-style view for comparing scenarios. Imports base-year amounts from CCH Axcess Tax or ProSystem fx Tax and prints client letters.

DDrake Tax Planner

Built into Drake Tax. Compares scenarios to the current return for 1040, 1120, 1120-S and 1065 returns. It's federal only, and scenarios don't carry over from year to year.

How to choose tax planning software

Decide what you're selling

A standalone plan, planning inside a monthly retainer, or advice to wealth management clients? Each one points to a different group of tools.

Start with your tax software

Check whether your current prep software already includes a planner. You may already be paying for one.

Match your clients

Business owners with several entities need multi-entity planning. Retirees and advisory clients need Roth and withdrawal scenarios.

Demo with a real return

Bring an anonymized return with an S corporation and a rental. Time how long it takes to get to a plan you'd actually send.

Test the mid-year update

Change the income and see how easy it is to refresh the plan. Planning only works if you keep it current.

Get pricing in writing

Ask about seats, plan limits, contract length and data export if you leave.

Software doesn't sell the plan. Your offer does.

We work with accounting firms every day, and we've seen it over and over. Firms buy great software, then struggle to sell planning because the offer isn't clear and the right clients aren't finding them.

Questions people ask

What is the best tax planning software for CPAs?

It depends on your firm. Corvee and TaxPlanIQ suit firms that sell planning as an advisory service. If you already use ProConnect, Lacerte, UltraTax, CCH or Drake, start with the planner built into that software. Bloomberg Tax Income Tax Planner is strong for deep multiyear projections.

How much does tax planning software cost?

As of November 2026, TaxPlanIQ starts at $397 a month and Holistiplan starts at $749 a year for 30 households. Corvee, Intuit Tax Advisor, Planner CS, Bloomberg Tax and CCH don't publish prices, so you'll need a quote. Drake Tax Planner is built into Drake Tax.

Is Corvee still available?

Yes. Corvee joined the Instead brand in April 2026. Existing customers kept the same login, data and pricing at instead.com/corvee.

Is Holistiplan for CPAs or financial advisors?

Holistiplan is aimed mainly at financial advisors, but it also has a section for tax professionals and CPAs. It's strongest for reviewing individual returns and finding planning opportunities.

Do I need tax planning software to offer tax planning?

No, but it helps. Software speeds up projections and makes savings easy to show. Many firms start with the planner in their tax prep software and upgrade once planning becomes a big part of their revenue.
