Tax Planning Software for CPAs: How to Evaluate It

Every planning demo ends on a clean projection. The client's income, a few alternatives, a tidy savings figure. What the demo doesn't show is what happens on a Tuesday in April, when a preparer loads a messy return, the Reviewer asks where a number came from, and the plan has to land in the client file.

That gap is where tax planning software for CPAs actually gets chosen. The differences that matter to a firm with a recurring S-corp book sit in six places: how returns come in, whether data imports from your tax software, what the client receives, where the files go afterward, whether each figure traces to a source, and how the vendor charges.

This guide gives you a criteria table to copy into your own evaluation, then short, dated notes on six planning tools. It's written for owners, tax partners and Reviewers at growing firms with a recurring S-corp book.

Six criteria for evaluating tax planning software

Use one copy of this table per vendor. You'll fill the last two columns during the demo, while the vendor's screen is still in front of you.

Return intake

Intake decides how much preparer time each plan costs before any modeling starts. Some tools take a PDF upload, some take many returns at once, and some pull straight from the tax software. Ask what happens with a scanned return, a partial return or a return with state schedules, and how an extraction error shows up for the preparer to fix.

Tax-software import

A direct import removes rekeying, but only for the packages the vendor supports. List the tax software your firm files with first. Then check that package against the vendor's own supported list. Comparison articles go out of date.

Output

The output is what your client keeps and what your firm is judged on. Check whether it's a PDF plan, a slide deck or a memo, and whether it carries your firm's name. A strong plan reads like a planning memo where each recommendation traces to a source figure and a Reviewer sign-off.

Integrations

Once it's signed, the plan and its source files need a home. Ask where they go: your cloud storage, your CRM, your practice management tool. Take the answer from the vendor's own integrations page.

Evidence trail

This is the row most demos skip. For every figure in the plan, can your firm open the source document or published limit, see its as-of date, and see who reviewed it and when?

One might argue the projection is the product and the source file is overhead. In practice, the file is what the Reviewer signs and what your firm reopens when a client asks why a number changed. Here's a quick test. Say a plan recommends that an S-corp owner max out 401(k) deferrals. The plan should show the 2026 elective deferral limit of $24,500 and cite where it comes from (IRS, Notice 2025-67, as of 2026-09-23). If the software can't hold that citation next to the figure, your staff will keep it somewhere else, or nowhere.

It's the same discipline a firm applies to a Reasonable Compensation Study, covered in how to document reasonable compensation in workpapers.

Pricing model

Planning tools price by monthly tier, by seat, by client, or as part of a larger software package. Two questions matter more than the sticker: what's included at your volume, and what your firm keeps if it stops paying. A plan you delivered two years ago shouldn't leave your file when the subscription ends.

How six tax planning tools line up on the criteria

The notes below come from each vendor's own pages, accessed 2026-09-23, and give you a starting point for your own tax planning software comparison. They cover what each vendor says it does. They don't test how well it works in practice. Features and prices change, so confirm on the vendor page before you buy.

Instead (formerly Corvee)

The Corvee site states that "Corvee is now part of Instead." Instead lists document upload for intake, integrations with Google Drive, OneDrive and Box, e-file, and workpapers and memos as outputs. Sources: instead.com and Corvee integrations, accessed 2026-09-23.

Holistiplan

Holistiplan is built advisor-first. It takes returns by PDF upload with OCR, lists Redtail and Wealthbox CRM integrations, and offers an API that requires approval. Sources: Holistiplan integrations and Holistiplan API help, accessed 2026-09-23.

TaxPlanIQ

TaxPlanIQ supports bulk upload of up to 100 Form 1040 returns and produces a white-label ROI summary, slide deck and report. Its tiers are $397, $697 and $997 per month as published on 2026-09-23; check the vendor page. Source: TaxPlanIQ pricing, accessed 2026-09-23.

Intuit Tax Advisor

Intuit Tax Advisor imports directly from Lacerte and ProConnect, which Intuit describes as "no scanning," and produces a branded PDF plan. Source: Intuit Tax Advisor features, accessed 2026-09-23.

Where TracePrep fits

TracePrep ships one workflow today: the Reasonable Compensation Study. Each figure in a Study traces to its source, a Reviewer signs off on the conclusion, and the workpapers belong to the Firm.

TracePrep is building a tax-planning workflow on the same evidence discipline. It's in development, and this page doesn't describe features, screens or integrations for it. If you want to see the discipline it starts from, see how a Study is built.

Conclusion

Run every demo against the same six rows. Weigh the evidence trail as heavily as the projection, because the projection is what sells the plan and the trail is what your firm has to stand behind later. If you want the Study workflow in your firm now, Get started.
