Best Tax Software for Small Firms and Solo Preparers (2026)

Drake is the suite we recommend most often to small practices, and the reason is the business model. One annual price covers federal and state packages and e-filing, with document storage and basic accounting tools included. Solo preparers with a small book can pay per return instead. For a practice where every subscription is felt, that predictability matters as much as any feature.

The software is quick and the support desk is the other pillar. Drake picks up during filing season with staff who know the product, which is worth a lot to a solo preparer with no IT department. The trade-offs are a plain interface that takes adjustment and thinner third-party integrations. For a book of individual returns and ordinary business entities, neither outweighs the value.

ProSeries is built for exactly the kind of practice this ranking covers. Preparers work on screens that look like the return, which makes training fast and mistakes easy to catch by eye. For a small office that keeps client books in QuickBooks, the Intuit connection is a daily convenience that Drake cannot fully match.

It ranks second because the value story is weaker. Pay-per-return pricing looks cheap at first and becomes expensive as volume rises, so a growing firm should do that math honestly against Drake's all-inclusive package. Firms that already live in the Intuit ecosystem, or that train new staff every season, will find the premium worth paying.

ATX is Wolters Kluwer's answer for small and mid-sized practices, and its core appeal is breadth in a forms-based package. Preparers work directly on the forms, and the library is large enough that unusual federal, state, and specialty filings rarely send you to another product. Its diagnostics help catch e-file rejects and overridden entries before they become problems.

It ranks below ProSeries because the day-to-day experience is less refined and there is no QuickBooks-style ecosystem pulling it together. Its packages are split by return type and volume, including a pay-per-return tier for low-volume preparers, which is flexible but takes care to price correctly. For a preparer who wants forms-based entry and broad coverage outside the Intuit world, it is a solid choice.

TaxAct Professional is the suite to look at when cost is the deciding factor. Pay-per-return pricing keeps the entry point low for a part-time or first-year preparer, and bundles cover firms with a predictable, modest return count. It handles individual returns and the common business entities, so a small practice is not boxed in on the basics.

The trade-off is the size of what surrounds it. Fewer professionals use TaxAct than Drake or ProSeries, so experienced hires and peer answers are harder to find, and integrations are limited. It also has less of a track record on complicated returns. For a low-volume practice with simple work, it is a sensible way to keep costs down.

TaxSlayer Pro serves a specific kind of small office very well: a preparer or storefront that files a high volume of individual returns in a compressed season. Bank product integration lets clients pay fees out of their refund, the Premium edition supports a paperless workflow with signature pads, and a web edition gives preparers access from any device.

That focus is also why it ranks fifth here. A small accounting firm with year-round bookkeeping clients and a mix of entity returns will find the suite's strengths aimed elsewhere, and its business return depth and workflow tools lag the leaders. For volume 1040 offices it deserves a close look. For most small CPA practices, the suites above fit better.
