How much does AI tax review software cost?

How much does AI tax review software cost?

AI tax review software is priced one of three ways. Usage-based tools charge per return, with published rates mostly between $20 and $45 and volume discounts below that. Some vendors carry per-user pricing over from traditional tax software. And platform vendors, Filed among them, charge one flat monthly fee for the whole firm, set by the size of the taxpayer book, with review, prep, and planning all included and no per-return, seat, or overage charges.

That is the number people search for. The more useful question is what each model actually costs your firm across a full season, and where the quotes hide the difference. That is the rest of this article.

How is AI tax review software priced?

Three models cover the market: per return, per user, and a flat platform fee.

Per-return pricing. You pay for each return the software touches. Published rates in the AI tax category cluster between $20 and $45 per return, a band independent pricing surveys keep confirming, sliding down at volume and sometimes carrying minimum commitments. Simple 1040s sit at the low end; entity returns, where they are supported at all, cost more. The catch shows up in March: every return you push through the tool is a new line on the bill, so the cost peaks exactly when you are busiest, and the meter makes teams selective about which returns get the good treatment.

Per-user pricing. Carried over from conventional tax software, which runs roughly $1,200 to $1,800 per user per year at mid-size firms; enterprise AI tools on this model quote in the range of $160 to $180 per user per month. Per-seat pricing punishes firms with large seasonal teams, which is exactly who needs review help, so the model is fading in this category.

Flat platform fee. One monthly fee covers the whole firm: every user, every return, prep and review and planning together. The fee is set by capacity, meaning the number of taxpayers in your book, and it does not move during the season. This is how Filed prices. Unlimited users, unlimited usage within your capacity, individuals and business entities both included, and the rate holds for the contract year rather than metering up in March.

What counts as a taxpayer in a pricing quote?

A taxpayer is any entity that files a return, and it is the unit most quotes are built on: an individual 1040, a partnership 1065, an 1120 or 1120-S, a 990. One client can easily be three taxpayers, a personal return plus two entities, so firms almost always have more taxpayers than clients. A quote scoped to clients and a quote scoped to taxpayers can differ by half, and the difference surfaces after you have signed. Filed scopes to taxpayers, and business entities are included rather than billed as a premium add-on.

Why is review usually bundled with prep?

Because good review runs on the same machinery as prep. To check a return against the client's source documents, the software has to read those documents, which is the expensive capability either way. Once a vendor has built it, splitting review into a separate SKU mostly creates billing complexity, so standalone review pricing is rare.

There is a second reason the flat-fee version of bundling matters for review specifically. Review only protects your book if it runs on your whole book. When each check costs money, firms ration it and the marginal return gets skipped. A flat platform fee removes the decision: at Filed, every taxpayer gets the full review layer on every return, because running it costs nothing extra.

What makes the price higher or lower?

Four inputs drive almost every quote in this category.

Taxpayer volume. The main lever in every model. Per-return tools discount at volume; platform fees scale with the size of the book. Either way, know your real taxpayer count, entities included, before you take a quote.

Entity mix. Some tools charge business returns at a multiple of the 1040 rate, or do not support them at all. Ask specifically. Filed covers 1040, 1065, 1120, 1120-S, 1041, and 990 work under the same fee.

Integration depth. Software that reviews returns from your existing tax system with no integration project is cheaper to start with. Published setup fees in the category run $2,000 to $15,000 where they exist; Filed Reviewer needs none, and firms typically run their first reviews within a day.

Timing and terms. Launch-window and first-year discounts are common across the category, and renewal pricing is where quotes differ most. Whatever number closes the deal, get year two in writing before you sign year one, and ask whether the rate is fixed for the term or can be repriced mid-year. Filed locks the monthly rate for the full contract year, with no mid-year repricing and no seat audits.

What hidden costs should you plan for?

Three, mostly: training time, switching timing, and definition gaps. Training is real even when it is free; plan for your reviewers to spend a few sessions learning to work from a flagged action list instead of a cold binder. Mid-season switching costs are real too, which is why most firms start in the off-season or on extensions. And on per-return contracts, overage rates on volume commitments deserve a line in the agreement, not a verbal answer. Flat-fee contracts avoid the overage question entirely; the thing to check instead is what happens when your starts to take in considerably more taxpayers, which at Filed is a resize at renewal rather than a surprise invoice.

Is AI tax review software worth the cost?

For most firms past a few hundred taxpayers, yes, and the math is short because review software pays for itself out of reviewer time. A fully loaded senior reviewer costs most firms $60 to $80 an hour, consistent with federal wage data for accountants and auditors once benefits and overhead are added. Firms using Filed save an average of 42 minutes per return across prep and review, which is $42 to $56 of loaded time per return. A firm with 2,000 taxpayers is recovering something on the order of $84,000 to $112,000 in reviewer capacity per season. Firms also report a 64% reduction in review cycles, which is capacity you keep instead of hiring for.

Run it against your own numbers: taxpayers per season, times minutes your reviewers spend per return today, times loaded hourly cost. That figure is your current annual spend on review. Any quote should be judged against it, not against zero.

What should you ask a vendor before signing?

Five questions surface most of the surprises.

  1. What does my whole firm cost at my actual taxpayer count? Not list price, and not per-client. Your book, entities included, all seats, year one and year two.
  2. How are business returns counted? Included in the same fee, billed at a multiple, or unsupported changes the comparison entirely.
  3. Can the price move mid-season? Overages, seat audits, and usage true-ups all mean yes. Get the answer in writing.
  4. Is there an implementation fee, and is it refundable? A money-back guarantee that excludes setup costs is a smaller guarantee than it sounds. Filed's covers the fees paid, with a written opt-out window and no negotiation.
  5. What do I stop paying for? The honest ROI conversation includes the seasonal staffing or outsourcing spend the software replaces.

Frequently asked questions

How much does Filed cost?

Filed charges one flat monthly platform fee for the whole firm, scoped to the number of taxpayers in your book. It covers unlimited users, prep, review, and planning, with individuals and business entities included and no per-return or overage charges, and the rate is fixed for the contract year. Every engagement carries a money-back guarantee. The number itself depends on your taxpayer count, so it comes from a short scoping conversation rather than a rate card.

What does per-return pricing typically cost?

Published AI tax tool rates mostly fall between $20 and $45 per return, discounting into the $30s and below at volume. Compare the season total at your volume against a flat fee before assuming per-return is cheaper; at a few thousand returns it usually is not.

Can you buy AI review without buying prep?

Rarely. Most vendors, Filed included, sell one contract covering both, because the underlying document-reading work is shared. Be cautious with pricing that itemizes them; the modules have a way of adding up.

Is there a minimum firm size for AI tax review software?

Often, yes. Filed's platform starts at firms with around 500 taxpayers a year, because the cross-book intelligence that justifies a platform fee needs a book of that size to pay off. Smaller practices are generally better served by per-return tools until their volume grows.

How do you get a real number for your firm?

Count your taxpayers, entities included, and price both models against that number. Filed Reviewer is part of one flat platform fee for the whole firm, backed by a money-back guarantee, and a scoping conversation takes 15 minutes. For the prep side of the cost picture, see the complete guide to AI tax preparation costs.
