The best tax software for professional tax preparer firms
Starting priceSee website (pay-per-return and unlimited module pricing)
Free planFree trial
Lacerte is Intuit's flagship professional product and the standard for firms that handle complicated returns at volume. Its diagnostics are the best in the industry at catching errors before filing, and the library of more than 5,700 forms covers virtually every entity type, from 1040s and 1120s to nonprofits and estates. Integration with QuickBooks pulls client bookkeeping data straight into the return, which matters when your clients run on QuickBooks.
Intuit sells Lacerte through pay-per-return and unlimited module pricing, with quotes required for the full picture. The honest catch is cost: G2 reviewers consistently call it expensive, with high-volume firms reporting five-figure annual bills, though they also say the time savings justify it above roughly 100 returns a year. If your practice lives in complex returns, Lacerte is the tool built for you.
What we like- Deepest diagnostics and complex-return handling
- 5,700+ forms
- QuickBooks integration
Watch out for- Among the most expensive options
- Pricing is opaque without a quote
Starting price$539 per year (pay-per-return)

ProSeries is Intuit's professional desktop product for small to mid-sized firms, and its forms-based design is the reason many preparers stick with it for decades. You see the actual tax form as you work, which makes data entry intuitive and review straightforward. The pay-per-return model starts at $539 a year plus per-return fees, while Basic 1040 packages start around $729 and Professional packages run $1,119 to $2,144 a year, so you can match the license to your volume.
The honest catch is Intuit's pricing trajectory: community reports of 40-54% renewal increases have made the second-year bill a surprise for some firms. Price the multi-year cost, not just the first year, before committing. For firms doing straightforward individual and small business returns, ProSeries remains a dependable workhorse.
What we like- Forms-based interface that is easy to learn
- Flexible pay-per-return or package pricing
- QuickBooks Online Accountant integration
Watch out for- Renewal price increases have annoyed long-time users
- Desktop-only without hosting

UltraTax CS is the compliance engine of Thomson Reuters' CS Professional Suite, and it is engineered for firms where a single client has a 1040, an S-corp, a partnership, and returns in five states. Enter data once and it flows across every related return, the multistate apportionment grid handles allocation on one screen, and integration with Accounting CS, Practice CS, and Checkpoint research keeps everything in one ecosystem. SurePrep and SafeSend integrations now automate document intake and e-signature delivery.
Pricing is custom based on users, return volume, and jurisdictions, so expect a sales conversation. The honest catch is that UltraTax's real power comes from the suite: without the other CS products, you are paying a premium for integration you are not using. Firms already committed to the Thomson Reuters ecosystem will get the most out of it.
What we like- Enter-once data sharing across returns
- Deepest CS Professional Suite integration
- Four-monitor multistate workflows
Watch out for- Quote-only pricing
- Full value requires other CS Suite products
Starting price$299.99 per year (Drake Tax Online)
Free planNo
Drake Tax is the software that working preparers recommend to each other when cost matters. The pay-per-return plan starts at $379.99 for 10 returns, Drake Tax Online starts at $299.99, and unlimited 1040 and Pro packages run $2,075 to $3,145 a year, all with every state included and unlimited support. For what it covers, it undercuts the premium products by thousands while handling federal, state, and business returns competently.
The honest catch is the interface, which looks like it belongs to an earlier decade and takes newcomers time to learn. But Drake's US-based support is consistently rated among the best in the industry, and free data conversion lowers switching costs. If you want maximum capability per dollar and can live with the look, this is the value pick.
What we like- Best price-to-capability ratio in the industry
- All 50 states included
- Legendary phone support
Watch out for- Interface looks dated
- Cloud option is newer than the desktop product
Starting price$1,395 per year (Pro Classic)
Free planFree trial
TaxSlayer Pro bundles everything a preparer needs into one price: unlimited returns, unlimited e-filing, all states, and unlimited support on every tier. Classic at $1,395 covers individual returns, Web at $1,595 adds browser access, and Premium at $1,695 adds the business suite with 1065s, 1120s, and 990s plus document management. The integrated bank products let clients deduct fees from their refunds, which is how many small practices get paid quickly.
The honest catch is platform: the desktop version is Windows-only, so Mac-based firms need the Web tier, and entity returns require Premium. But for firms that want one predictable annual price with no per-return meter running, TaxSlayer Pro's all-inclusive model is refreshingly simple.
What we like- Unlimited returns and e-filing on all tiers
- Integrated bank products and refund transfers
- TaxesToGo mobile app
Watch out for- Desktop version is Windows-only
- Business returns require the Premium tier
Starting pricePay per return
Free planFree trial
ProConnect Tax is Intuit's online professional product, and the pitch is simple: prepare returns from anywhere with nothing to download or maintain. It imports data from QuickBooks Online Accountant, offers pay-per-return pricing that fits seasonal and growing practices, and integrates with the broader Intuit Accountant Suite for firms standardizing on Intuit's ecosystem. Free trial access lets you test the workflow before buying returns.
The honest catch is arithmetic: per-return pricing is cheap at 30 returns and expensive at 300, so compare the pay-per-return total against an unlimited package before your first busy season. Cloud dependence is also real; if your internet is unreliable, a desktop product is safer. For modern, distributed practices that live in QuickBooks Online, ProConnect is the natural fit.
What we like- Fully cloud-based, no installs
- Integrates with Intuit Accountant Suite
- Automatic data import from QuickBooks
Watch out for- Pay-per-return costs scale with volume
- Requires reliable internet
Starting price$1,249 per year (ATX 1040)
Free planFree trial
ATX has earned its reputation as the easiest professional tax software to learn, which matters when you are training seasonal staff in December. The forms-based interface walks preparers through returns with minimal training, the library of more than 6,000 forms covers federal, state, and local returns, and small touches like the live refund meter help preparers catch issues as they enter data. The ATX 1040 package starts at $1,249 with higher tiers adding more capacity.
The honest catch is that the base 1040 package handles business returns on a pay-per-return basis, so firms with entity clients should price the higher packages. ATX is also firmly desktop-centric in a market moving to the cloud. For small firms that value simplicity over everything else, it remains one of the friendliest options.
What we like- Genuinely easy to learn
- 6,000+ form library
- Refund meter shows balance due live
Watch out for- Pay-per-return add-ons for business returns on the base package
- Desktop-centric
Starting price$2,814 per year (Tax Essentials 100, new customers)
Free planNo
CCH Axcess Tax is the cloud platform that most of the largest US firms run on, now packaged for smaller practices through Tax Essentials 100 at $2,814 for new customers with up to four tax professionals. Everything is cloud-native: real-time collaboration, actionable diagnostics, onscreen review, and integration across the CCH Axcess platform with AI-powered document ingestion that reduces manual entry. It scales from a four-person firm to a national practice without a platform change.
The honest catch is that this is enterprise software with enterprise pricing and sales complexity, and the discounted Essentials packages are available to new customers only. But if your firm plans to grow and wants to choose its tax platform once, Axcess Tax is the one built for the long run.
What we like- Fully cloud-native with real-time collaboration
- AI-enabled data ingestion
- Trusted by the largest US firms
Watch out for- Enterprise-grade pricing
- Essentials packages are new-customer only
How we chose
We evaluated these platforms using vendor pricing pages, product documentation, and FAQ pages current as of October 2026, cross-checked against reviews from preparers on G2, Capterra, Reddit, and the Journal of Accountancy's tax software surveys. We focused on form coverage, e-filing capability, pricing transparency, cloud versus desktop deployment, and fit for different firm sizes. We did not test the software hands-on, and professional tax pricing changes annually, so confirm current pricing with each vendor before tax season.
Match the software to your firm's size and season
The right choice depends mostly on return volume and complexity. Solo preparers and seasonal practices do best with pay-per-return models: ProConnect Tax, Drake's pay-per-return plan, or ProSeries pay-per-return keep your fixed costs near zero when volume is unpredictable. Firms filing a few hundred individual returns should compare unlimited 1040 packages from Drake, TaxSlayer Pro, and ProSeries side by side.
Firms with business entity clients, multistate returns, and staff need the premium tier: Lacerte, UltraTax CS, or CCH Axcess Tax. The license costs more, but the diagnostics, data sharing, and workflow tools save enough per return to pay for themselves. The expensive mistake is not the software price; it is paying for capability you never use or outgrowing a cheap platform mid-season.
Cloud versus desktop still matters
Tax software is mid-migration from desktop to cloud, and your choice affects daily life more than any feature list. ProConnect Tax and CCH Axcess Tax are cloud-native: work from anywhere, no server maintenance, automatic updates. Lacerte, ProSeries, UltraTax CS, Drake, ATX, and TaxSlayer Pro are desktop products at heart, with hosting options from the vendor or third parties like Rightworks.
Desktop still wins for offline reliability and speed on large returns, and some preparers simply work faster in the software they know. Cloud wins for distributed teams, multi-location firms, and anyone tired of maintaining a server. If you are switching platforms anyway, switching deployment models at the same time is worth considering, because the next decade of these products is clearly in the cloud.
Frequently asked questions
What is the best tax software for a new tax practice?
ProConnect Tax or Drake's pay-per-return plan are the best starts, since you pay only for the returns you actually file. Once you know your volume, compare unlimited packages from TaxSlayer Pro and Drake before your second season.
How much does professional tax software cost?
It ranges from $299.99 a year for Drake Tax Online to five figures annually for high-volume Lacerte or UltraTax CS deployments. Most small firms pay between $1,000 and $3,500 a year. Always price the second year, since renewal increases are common.
Is Lacerte or ProSeries better for a small firm?
ProSeries is the better fit for most small firms: it is cheaper, forms-based, and easier to learn. Lacerte is worth the premium only when you regularly handle complex returns, multi-entity clients, or high volume, where its diagnostics and automation pay for themselves.
Can I switch tax software without re-entering client data?
Most vendors offer free data conversion from competing products, including Intuit, Drake, and Wolters Kluwer. Conversion covers prior-year returns and client data, though some review and cleanup is usually needed. Start the migration in the fall, not January.
Do I need cloud tax software?
Not necessarily. Cloud software suits distributed teams and multi-location firms, while desktop software is faster offline and often cheaper. If you want desktop reliability with remote access, vendor hosting options for Lacerte, ProSeries, and UltraTax CS split the difference.
What is pay-per-return pricing?
You buy the license and pay a fee for each return you file instead of buying an unlimited package. It fits seasonal preparers and new firms with unpredictable volume. Once you file roughly 100 or more returns, an unlimited package usually costs less.
