Lacerte vs. ProSeries vs. Drake Tax vs. UltraTax CS: Which Professional Tax Software Fits Your Practice?

You are about to spend somewhere between $300 and $10,000 a year on the single tool your entire busy season depends on — and the wrong choice does not just cost money, it costs returns. Pick software that lacks the forms your clients need and you will hand-prepare stragglers in April. Pick enterprise-grade power for a 60-return solo practice and you will pay $100 per return for capacity you never touch. Every year the Journal of Accountancy asks the people who actually prepare returns for a fee what they use and how they rate it, and the 2026 survey — 1,808 AICPA members reflecting on the 2025 tax season — is the closest thing this industry has to an unbiased buyer's guide. Here is what it says about the four biggest names, and how to match one to your practice.

This guide compares Lacerte, ProSeries, Drake Tax, and UltraTax CS on price per return, form coverage, ease of use, and support ratings from the 2026 practitioner survey, then gives you a decision framework based on firm size and return mix.

What the 2026 Survey Actually Says​

The survey asked preparers to name their software from 13 listed products. Four brands dominate, all from just three vendors: Intuit makes Lacerte and ProSeries, Thomson Reuters makes UltraTax CS, and Drake Software makes Drake Tax. (A fourth vendor, Wolters Kluwer, fields the CCH line, which sits just outside this comparison.)

By share of preparers:

• UltraTax CS, 22.3% — the most-used professional package, and the only one with serious adoption at every firm size.
• Lacerte, 16.7% — gained nearly a full point from last year, swapping places with Drake.
• Drake Tax, 14.3% — down two points, but still the value leader by a wide margin.
• ProSeries, 11.0% — Intuit's other brand, concentrated among smaller firms.

By overall satisfaction (5-point scale), Drake Tax and Lacerte tied for the lead at 4.4. But the headline numbers hide the real story: each product wins a different category, and the category you care about depends entirely on your return volume, client complexity, and tolerance for busy-season support calls.

Price and Price Per Return: Do the Breakeven Math​

Price is the single biggest differentiator in the survey, and the responses are almost comically polarized. Drake Tax's price was named a top like by 86% of its users — the highest score for any trait of any product — while more than 80% of Lacerte and UltraTax CS users named price a top dislike. Only 10.6% of Drake users faulted its price.

Here is the published pricing landscape for the current season:

• Drake Tax Online starts at $299 for the first user plus $49.99 per return — the cheapest credible entry point among serious pro tools. The desktop line runs from $2,075 for unlimited 1040s (single user) to $2,695 for unlimited returns of all types.
• ProSeries starts at $539 per year for the pay-per-return license, with federal 1040s at $69 each under Intuit's tax-year 2026 price sheet ($61 per state, $99 per federal business return). Basic Unlimited is $1,119 for unlimited 1040s, and Professional unlimited tiers run roughly $2,100 to $2,600.
• Lacerte pay-per-return starts at a $599 license plus per-return charges, with unlimited tiers priced well above ProSeries. List prices for full unlimited Lacerte are quote-level for most configurations.
• UltraTax CS publishes no list price at all. Thomson Reuters quotes by user count, return volume, and states, and firms consistently report it as the most expensive of the four.

The decision that matters is pay-per-return versus unlimited, and it is pure arithmetic. Take ProSeries: the pay-per-return license costs $539 and Basic Unlimited costs $1,119, so the $580 gap divided by $69 per federal 1040 puts the breakeven at about 9 individual returns — past that, unlimited wins even before you count state returns. For Drake Tax Online versus desktop 1040 Unlimited, the gap is $2,075 minus $299, or $1,776, divided by $49.99 per return: about 36 returns. Below 36 returns, the cloud pay-per-return plan is cheaper; above it, you are overpaying for flexibility.

Run this math with your actual return count before every renewal. Practices grow into — and shrink out of — the right tier constantly, and the survey suggests most preparers pick a tier once and stop thinking about it.

Form Coverage: Who Has the Form When April Comes​

A cheap package that lacks the form you need is the most expensive package of all. The survey asked users directly whether their software contained every form they needed, and the answers draw a clear hierarchy:

• UltraTax CS: 92.1% said yes — the best in the survey. This is what you are paying for: multi-entity, multi-state, and specialist coverage that rarely leaves a gap.
• Drake Tax: 83.7% said yes — surprisingly strong for the value pick, even though only a third of its users named comprehensiveness a top strength. It covers more than its reputation suggests.
• ProSeries: 31.8% said it lacked forms they needed — the worst in the survey, and the product's clearest weakness. Only 40% of ProSeries users named form coverage a top like.

Lacerte sits in the upper tier on coverage — Intuit positions it as the step up from ProSeries precisely for firms outgrowing ProSeries's form library, with specialist forms like estate (706) and benefit plan (5500) coverage that ProSeries configurations often lack.

The practical takeaway: if your practice is 1040s plus a handful of straightforward S-corps and partnerships, Drake or ProSeries covers you. If you touch consolidated corporations, multi-state business returns, estates, or exempt organizations, the coverage gap is the reason Lacerte and UltraTax exist — and the survey's multistate complaint write-ins (dozens of them, the largest custom-complaint category) suggest state coverage deserves its own line item in your evaluation.

Ease of Use: Four-Way Tie at the Top, One Clear Laggard Elsewhere​

Ease of use produced the survey's most even result: Drake Tax, Lacerte, ProSeries, and ATX all scored 4.4 out of 5. (The laggard was CCH Axcess Tax at 3.6 — outside this comparison, but a useful calibration point for how bad "hard to use" can get.)

Within the tie, the texture differs:

• ProSeries earned the highest ease-of-use approval as a named like — nearly 80% of its users picked it, the best percentage for that aspect. Its forms-based interface is the gentlest on-ramp of the four.
• Drake Tax pairs its 4.4 ease rating with a standout 4.7 for handling on-the-fly updates — the mid-season IRS guidance patches every preparer dreads — well above the 4.3 all-product average. It also scored 4.7 for ease of updating and installation.
• Lacerte matches the 4.4 ease rating while serving more complex returns, which arguably makes its score the most impressive: it is easy to be usable when your returns are simple.
• UltraTax CS trails the other three slightly on ease but leads where power users feel it: it was the only product above the (dismal) average for importing data, at 3.5 versus 3.4, and led integration with other software at 3.4. Data import and integration are the survey's lowest-rated categories across the board — nobody is good at them, but UltraTax is least bad.

One honest caveat from the survey's write-ins: many preparers named familiarity itself — "I've used it for decades," "lots of muscle memory" — as their top like. Switching costs are real. Budget a full season of reduced speed when you change platforms, whatever the ratings say.

Support Ratings: Drake in a League of Its Own​

Close to three-quarters of survey respondents needed vendor support during the season, so support quality is not a footnote — it is a busy-season survival factor. And here the survey has an unambiguous winner:

• Drake Tax took the top ratings for both support quality (4.2) and ease of obtaining it (4.3). More than half of Drake users (56.4%) named customer support a top like — no other product came close. Its training also rated highest at 4.4.
• The other three cluster in the middle of the pack on support, with telephone remaining the principal support channel across all brands. Email and live chat usage, after years of growth, leveled off this year.

If you are a solo preparer with no IT staff and no senior preparer down the hall, this category should weigh heavily. A 4.2 support rating versus a middle-of-pack one is the difference between a 10-minute fix and a lost evening in mid-March.

Which One Fits Your Firm Size​

The survey cross-tabulates product choice against firm size, and the pattern is stark:

• Sole preparers: Drake Tax and ProSeries together claim close to half. Nearly half of Drake's own user base (46.5%) are sole practitioners, and 93.4% of Drake users said their software would suit a new practice — the highest in the survey. If you are hanging a shingle, start here.
• Small firms (2–10 preparers): Lacerte territory. This is where practices typically outgrow ProSeries's form library and Drake's sweet spot. Lacerte's tied-best 4.4 overall rating with deeper coverage is built for exactly this transition.
• Mid-size and large firms: UltraTax CS. It was used by more than 30% of respondents in the largest firms, with significant representation at every size. Multi-office, multi-state, multi-entity practices pay the premium for coverage and CS Suite integration.

A useful smell test: if more than 80% of a product's users complain about its price yet keep renewing — as with Lacerte and UltraTax — the product is delivering value its users cannot get elsewhere. The question is only whether you need that value yet.

Track Your Own Cost Per Return​

Whichever package you choose, the survey's pricing lesson applies to your own books: software is only cheap or expensive relative to the returns it produces. Book the annual license as a prepaid expense amortized across the season, then divide by returns filed to get your true cost per return — the number that tells you whether next year's tier change is justified.

A plain-text ledger makes this trivial to track year over year:

2026-01-15 * "Drake Software" "Drake Tax 1040 Unlimited - 2026 season"
  Assets:Prepaid:Tax-Software                          2075.00 USD
  Assets:Checking:Business                            -2075.00 USD
 
2026-04-30 * "Amortize tax software over busy season"
  Expenses:Professional:Tax-Software                   2075.00 USD
  Assets:Prepaid:Tax-Software                         -2075.00 USD

At 150 individual returns, that $2,075 license costs $13.83 per return — compare it against the $49.99 pay-per-return alternative ($7,498.50 for the same volume) and the unlimited tier pays for itself nearly four times over. Run the same division on your own numbers each May, when the season's return count is final and next year's renewal is still negotiable.

Common Mistakes When Choosing Tax Software​

Buying for the firm you want to be. The most expensive mistake is purchasing UltraTax-level coverage for a 1040 practice "because we're going to grow into business returns." Growth that has not happened yet should not pay enterprise prices. Start with the value tier and upgrade when your return mix — not your ambition — demands it.

Ignoring the state-return fine print. Multistate returns drew the survey's largest pile of custom complaints. Before you commit, verify exactly which states are included in your tier and what each additional state costs — ProSeries Basic Unlimited, for example, covers only four states, with the rest pay-per-return.

Comparing license prices instead of per-return costs. A $599 license that charges $100 per business return can easily exceed a $2,695 unlimited package by your fortieth return. Always multiply out your actual mix: individual federal, state, business federal, business state.

Underestimating the switching cost. The survey's "muscle memory" write-ins are a warning. Even a strictly better package costs you speed for a full season. Time a switch for the summer, run prior-year returns through the new system as training, and keep the old license through at least one extension season as a reference.

Skipping the AI question. The 2026 survey found 65% of respondents already using AI in tax research, and the share with no AI plans fell from 24.3% to 16% in a single year. Ask each vendor what AI-assisted review, research, and planning tools ship with — or cost extra on top of — the tiers you are comparing.

Your Next Step​

Pull your return counts from last season — individual, business, and state — and run the pay-per-return versus unlimited breakeven for two finalists, not four. Solos and new practices should compare Drake Tax against ProSeries; growing firms should compare Lacerte against Drake Tax Pro Unlimited; multi-state and multi-entity practices should get the UltraTax CS quote and compare it against Lacerte Unlimited. Price the exact tiers your volume justifies, confirm your states are included, and trial the winner on prior-year returns before busy season. The survey tells you what 1,808 preparers think — but your return mix is the only vote that counts.
