Best Tax Software for Tax Preparers in 2026: 9 Tools Compared

Drake Tax is the value story in professional tax software, and the pricing explains why. Drake Tax Online starts at $299.99 for the tax year, and the pay-per-return option is listed at $379.99, which gives a new practice a low-cost way in without an unlimited bundle it cannot fill. The desktop version covers individual and business returns, with e-filing, diagnostics, and multi-user access for a team.

The catch is feel. Drake is form-based, which experienced preparers often like for speed, but new staff may need more training than with a more guided interview style. Integration with outside practice tools is also weaker than some rivals. For a solo preparer or small firm that wants predictable cost and a complete return workflow, Drake is a strong first shortlist pick.

Lacerte is Intuit's professional desktop product for firms with complex, high-value returns. Its pay-per-return licence starts at $599 per year, with return charges on top, so the entry figure is not the full season cost. What you get for that is a deep forms library, input-based preparation, and diagnostics suited to multi-entity, multi-state, and pass-through work.

That depth suits a firm that already handles complex returns and has staff who know the product. A new solo practice may find the total cost and learning curve harder to justify than Drake or TaxSlayer Pro. Choose Lacerte when your return mix includes the specialist forms and complex cases that cheaper tools handle less well, and price the full return volume, not just the licence.

ProSeries is the other main Intuit desktop product, and it suits firms that focus on individual returns. Its pay-per-return licence starts at $539 per year, and it offers bundles for higher volume. Many preparers find its workflow easier to learn than Lacerte, which matters when a firm hires seasonal staff each spring and needs them productive quickly.

The limit is specialist coverage. ProSeries does not cover every form Lacerte does, so a firm with unusual returns should test its ten strangest cases before committing. Modular pricing can also add up once state returns and business entities are included. For a 1040-focused practice that wants Intuit depth without Lacerte cost, ProSeries is a sensible middle ground.

UltraTax CS is Thomson Reuters' professional tax product, and it fits best in a firm already using other CS Professional Suite tools such as practice management or document systems. It handles related entities, state allocation, and complex multi-state work, which is why many mid-size firms stay with it despite its cost and learning curve.

Pricing is quote-only, based on users, return volume, modules, and jurisdictions, so a firm cannot budget from a published entry price alone. That also means a quote comparison is essential. Shortlist UltraTax CS when your firm needs deep multi-state coverage and already runs Thomson Reuters tools, and expect a migration and training cost if you move to it from a simpler product.

CCH Axcess Tax is Wolters Kluwer's cloud tax platform, aimed at growing and multi-office CPA firms. Because it is cloud-based, staff in different offices can work on the same client data without desktop installs, and it connects with other Axcess products for documents, workflow, and firm management. Newer versions add AI-assisted features for review and research.

The pricing is quote-only and sold as packages after a consultation, so budgeting needs a direct quote. Tax is also separate from the document and workflow products, which can raise the total suite cost. Choose CCH Axcess Tax when cloud access and a single Axcess environment matter more than a low published entry price.

TaxAct Professional suits budget-focused practices that want a choice between paying per return and buying an unlimited bundle. Published comparisons list a 1040 bundle and a complete bundle at different price points for single and multi-user setups, with prices rising at set dates, so the current vendor price is the only reliable figure. That flexibility helps a firm match pricing to its actual volume.

The product is simpler than Lacerte or UltraTax CS, which is a strength for routine 1040 work and a limit for complex cases. Check that it covers the forms your clients need, especially for business and specialist returns, before switching. For a small practice that wants unlimited 1040 filing without enterprise cost, TaxAct Professional deserves a trial.

TaxSlayer Pro is built for seasonal and high-volume 1040 offices, and its pricing reflects that: the Classic package starts at $1,395 per year with unlimited 1040 filing included. For an office that files hundreds of individual returns in a short season, a flat unlimited price is easier to budget than per-return charges that climb with volume.

The entry price is higher than Drake Tax Online, so a low-volume practice may pay more for capacity it does not use. It is also less suited to complex enterprise work than UltraTax CS or CCH Axcess Tax. For a seasonal office with known high 1040 volume, TaxSlayer Pro offers predictability and a straightforward workflow.

ATX, also from Wolters Kluwer, suits sole practitioners and small firms that want a deep forms library at a published price. Its pay-per-return option is listed at $939 for six returns included, and higher bundles cover larger volumes. For a small firm that files a mix of individual and business returns, ATX gives more form depth than some budget tools.

The product feels older than cloud-first rivals, and the top bundles cost several thousand dollars per year, so the entry price is only part of the story. A solo preparer should trial the interface and confirm that the forms they need are in the package they intend to buy. For a small firm that values form coverage over a modern cloud interface, ATX is worth testing.

ProConnect Tax is Intuit's cloud tax product, and it suits firms that want browser-based preparation without desktop installs or hosting. It fits well with a QuickBooks Online client base, since client data can flow between systems, and some bundles include Intuit Sign for e-signatures. For a remote or multi-location team, cloud access is a real advantage over desktop-only tools.

Pricing is bundle-based, with essentials packages covering a set number of individual returns and one paid user, while business returns cost extra. That structure needs careful counting: a firm with many business returns may pay more than the headline bundle suggests. Choose ProConnect Tax when cloud access and the Intuit ecosystem matter most, and price your full return mix before committing.
